Description
Technical Field
The present invention relates to a paint mist collecting device disposed in a spray booth.
Background

The paint mist collecting device is formed by a plurality of vertical plates with openings and slits, the slits of the vertical plates are matched with the slits of the horizontal plates, and the paint mist collecting device is formed by a plurality of horizontal plates with the openings and slits inserted into the vertical plates.
Since a curved air passage is formed in the lattice structure, the spray booth exhaust gas passes through the curved air passage. As a result, the number of collisions between the spray booth exhaust gas and the cross plate and vertical plates increases, and the paint mist collection efficiency improves.
In a preferred embodiment of the present invention, the paint mist collecting device includes a plurality of first cross plates having a plurality of elongated openings and a plurality of slits extending from a peripheral edge to a longitudinal extension of the elongated openings, a plurality of second cross plates having a plurality of elongated openings and a plurality of slits extending from a peripheral edge to a longitudinal extension of the elongated openings, and a plurality of longitudinal plates having a plurality of elongated openings and a plurality of slits extending from a peripheral edge to a longitudinal extension of the elongated openings, wherein the first cross plates and the second cross plates are alternately arranged with gaps therebetween to form a cross plate aggregate, a portion between adjacent elongated openings of the second cross plates is opposed to the elongated openings of the first cross plates, and a portion between the elongated openings of the second cross plates and adjacent elongated openings of the first cross plates is opposed to each other, the plurality of longitudinal plates are arranged with gaps therebetween to form a longitudinal plate aggregate, and the slits are aligned with the longitudinal plate aggregate, and the cross plates are stacked together to form a grid aggregate, and the air passage is formed in the cross plate aggregate.

If the paint mist collecting means is arranged such that the exhaust gas of the spray booth flows from one end surface of the cross plate aggregate opposite to the inlet opening toward the other end surface of the cross plate aggregate opposite to the outlet opening, a large amount of paint mist is collected at an upstream portion of the curved air passage formed by the cross plate aggregate and the vertical plate aggregate, and the amount of collected mist decreases as it goes downstream. Since the trapped paint mist is accumulated in the space between the adjacent first and second cross plates, it is reasonable to decrease the interval between the first and second cross plates from one end surface of the cross plate assembly facing the inlet opening to the other end surface facing the outlet opening.
In a preferred embodiment of the present invention, a filter is disposed in the case adjacent to the other end surface of the cross plate assembly facing the outlet opening.
In addition to the lattice structure, a filter is disposed, and the paint mist collection efficiency is improved.
In a preferred embodiment of the present invention, the vertical plate aggregate is constituted by a first portion into which the horizontal plate aggregate is inserted from one end side of the elongated opening of the horizontal plate, and a second portion into which the horizontal plate aggregate is inserted from the other end side of the elongated opening of the horizontal plate.
By dividing the vertical plate aggregate into a first portion into which the horizontal plate aggregate is inserted from one end side of the elongated opening of the horizontal plate and a second portion into which the horizontal plate aggregate is inserted from the other end side of the elongated opening of the horizontal plate, sliding resistance at the time of insertion is reduced, and assembling operation of the lattice structure is facilitated.
In a preferred embodiment of the present invention, the lattice structure formed by the plurality of transverse plates and the plurality of longitudinal plates in cooperation with each other is foldable.
The lattice structure in which the plurality of vertical plates are inserted with the plurality of horizontal plates has no fastening portion such as adhesion, and therefore can be easily folded, and can be easily restored to a three-dimensional structure from a folded state. By folding, the paint mist collecting device is easily transported.
In a preferred form of the invention, the cross plates, the longitudinal plates and the box are formed from cardboard.
The paint mist collecting device made of cardboard such as cardboard, thick paper, corrugated paper, etc. is light, and thus is easy to transport and easy to handle after use.
In a preferred embodiment of the present invention, the surface of the cross plate facing the inlet opening, the two surfaces of the vertical plate, and the inner surface of the case are subjected to surface treatment for improving the efficiency of capturing paint mist.
The surface of the cross plate facing the inlet opening, the two surfaces of the vertical plate, and the inner surface of the case are subjected to surface treatment for improving the paint mist collecting efficiency, so that the paint mist collecting efficiency is improved.

In the present invention, there is provided a paint mist collecting device, wherein a plurality of openings and a plurality of vertical plates sandwiching the openings and extending from the peripheral edge are formed, a plurality of horizontal plates sandwiching the openings and extending from the peripheral edge are inserted with the respective slits being matched with the slits of the horizontal plates, the plurality of vertical plates cooperate with the plurality of horizontal plates to form a lattice structure, a curved air passage is formed in the lattice structure, the lattice structure is accommodated in a case, an outlet opening is formed in one of a pair of wall surfaces of the case facing the openings of the horizontal plates, an inlet opening is formed in one of a pair of wall surfaces of the case facing the lattice shape of the lattice structure, and the inlet opening is disposed in proximity to the other of the pair of wall surfaces of the case facing the openings of the horizontal plates.
In the case where the paint mist collecting device is disposed in the straight-line advancing portion of the spray booth exhaust path, it is reasonable to form the inlet opening and the outlet opening in the wall surfaces of the case body that face each other. However, it is difficult to provide a paint mist collecting device having an inlet opening and an outlet opening on the wall surfaces of the case facing each other in a curved portion of the spray booth exhaust path to perform the intended function.
The paint mist collecting device according to the present invention has an inlet opening and an outlet opening that are orthogonal to each other, and therefore can be provided in a curved portion of an exhaust path of a spray booth to perform a desired function.
In a preferred embodiment of the present invention, the lattice structure is not opposed to the inlet opening, and the vertical plate extending from the lattice structure is opposed to the inlet opening.
If the lattice structure is opposed to the inlet opening, the spray booth exhaust gas flowing into the lattice structure through the inlet opening toward the lattice shape collides with the spray booth exhaust gas flowing in parallel with the lattice shape in the lattice structure toward the outlet opening, and the airflow in the lattice structure is disturbed, and there is a possibility that the paint mist collecting efficiency is lowered. Therefore, it is desirable that the lattice structure is not opposed to the inlet opening. On the other hand, in order to position the lattice structure in the case, it is desirable that the vertical plate extends from one of a pair of wall surfaces of the case facing the opening of the horizontal plate up to the other. If the vertical plate is extended from the lattice structure, the vertical plate can be extended from one of the pair of wall surfaces of the case facing the opening of the horizontal plate up to the other. In this case, the extension of the longitudinal plate becomes opposite to the inlet opening.
In a preferred embodiment of the present invention, the lattice structure and the vertical plate extending from the lattice structure face the inlet opening.
If the vertical plate is extended from the lattice structure, the extension portion becomes not lattice structure, and thus strength is lowered. If the cross plate is disposed in the vertical plate extension, the lattice structure having the curved air passage formed therein is expanded, and the strength of the vertical plate extension can be prevented from decreasing. As a result, a part of the lattice structure faces the inlet opening, but when the extension of the vertical plate increases in size according to the size of the inlet opening, it may be necessary to dispose the horizontal plate on the extension of the vertical plate.
In a preferred embodiment of the present invention, no opening is formed in the extension portion of the vertical plate extending from the lattice structure.
Since the extension portion of the vertical plate is not formed in the lattice structure having the curved air passage formed therein, the opening is not necessary.
In the present invention, there is provided a paint mist collecting device, characterized in that a plurality of openings and a plurality of vertical plates sandwiching the openings and extending from the peripheral edge are formed, a plurality of openings and a plurality of horizontal plates sandwiching the openings and extending from the peripheral edge are formed by fitting the slits of the vertical plates and the slits of the horizontal plates, the plurality of vertical plates cooperate with the plurality of horizontal plates to form a lattice structure, a curved air passage is formed in the lattice structure, the lattice structure is accommodated in a case, an outlet opening is formed in one of a pair of wall surfaces of the case opposing the openings of the horizontal plates, an inlet opening is formed in the other of a pair of wall surfaces of the case opposing the openings of the horizontal plates, a hollow cover is mounted to an end of the case where the inlet opening is formed, and an inlet opening communicating with the inlet opening of the case is formed in a side surface of the cover.
In the above-described paint mist collecting device, the spray booth exhaust gas flows into the lattice structure through the inlet opening of the lid body and the inlet opening of the tank body. The inlet opening of the cover body is orthogonal to the outlet opening of the case body, so that the paint mist collecting device can be provided at a curved portion of the exhaust path of the spray booth.

Detailed Description
As shown in fig. 1, a dry paint mist collecting device 1 according to an embodiment of the present invention includes: a lattice structure 4 composed of three first transverse plates 2a, three second transverse plates 2b, and ten longitudinal plates 3; and a case 5 formed with an inlet opening 5a and an outlet opening 5b at opposite sides. The lattice structure 4 is housed in the case 5 to form the paint mist collecting device 1.
As shown in fig. 2, the first cross plate 2a is formed of a rectangular cardboard such as cardboard, thick paper, or corrugated paper, and is formed with five elongated openings 2a1 extending in parallel at predetermined intervals, and a plurality of slits 2a2 which sandwich the elongated openings 2a1 and extend from a peripheral edge on one end side in the longitudinal direction of the elongated openings 2a1 and a peripheral edge on the other end side in the longitudinal direction to a middle of the length of the elongated openings 2a1 extending in the longitudinal direction.
As shown in fig. 3, the second cross plate 2b is formed of a rectangular cardboard such as cardboard, thick paper, or corrugated paper, and is formed with four elongated openings 2b12 extending in parallel with a predetermined interval therebetween, and a plurality of slits 2b22 which sandwich the elongated openings 2b1 and extend from a peripheral edge on one end side in the longitudinal direction of the elongated openings 2b1 and a peripheral edge on the other end side in the longitudinal direction thereof to a middle of the length of the elongated openings 2b1 extending in the longitudinal direction.
As can be seen from fig. 1, the first cross plates 2a and the second cross plates 2b are alternately arranged with a gap therebetween to form a cross plate assembly 2'. As shown in fig. 4, in the diaphragm assembly 2', a portion between adjacent elongated openings 2b1 of the second diaphragm 2b is opposed to the elongated opening 2a1 of the first diaphragm 2a, and the elongated opening 2b1 of the second diaphragm 2b is opposed to a portion between adjacent elongated openings 2a1 of the first diaphragm 2 a. When the openings 2a1, 2b1 are seen from the front, the slit 2a2 overlaps with the slit 2b2 as shown in fig. 4.
As shown in fig. 5, the vertical plate 3 is composed of a first portion 3a and a second portion 3b, the first portion 3a is formed of a rectangular cardboard such as cardboard, thick paper, corrugated paper, etc., and five elongated openings 3a extending in parallel with a predetermined interval are formed 1 And an elongated opening 3a 1 Sandwiched and from the elongated opening 3a 1 Extends from the periphery of one end side in the longitudinal direction up to the elongated opening 3a 1 A plurality of slits 3a extending in the longitudinal direction 2 The second portion 3b is formed of a rectangular cardboard such as cardboard, thick paper, corrugated paper, or the like, and is formed with five elongated openings 3b extending in parallel with a predetermined interval therebetween 1 And an elongated opening 3b 1 Sandwiched and from the elongated opening 3b 1 Extends from the periphery of one end side in the longitudinal direction up to the elongated opening 3b 1 A plurality of slits 3b extending in the longitudinal direction 2 . The first portion 3a and the second portion 3b are formed in a symmetrical shape. As shown in fig. 1 and 6, the first portion 3a and the second portion 3b are formed by abutting the peripheral edges of the one end side against each other to form a vertical plate 3.
As can be seen from fig. 1, the first portions 3a of the ten vertical plates 3 are arranged with a gap therebetween to form a first vertical plate aggregate 3', and the second portions 3b of the ten vertical plates 3 are arranged with a gap therebetween to form a second vertical plate aggregate 3".
As shown in fig. 1, the first vertical plate aggregate 3' has its own slit 3a 2 Slit 2a of cross plate assembly 2 2 、2b 2 Aligned from the elongated opening 2a 1 、2b 1 The transverse plate assembly 2 'is inserted into the periphery of one end side in the length direction, and the second longitudinal plate assembly 3' has its own slit 3b 2 Slit 2a of cross plate assembly 2 2 、2b 2 Aligned from the elongated opening 2a 1 、2b 1 The other end side peripheral edge of the transverse plate assembly 2' is inserted, and the transverse plate assembly 2', the first vertical plate assembly 3' and the second vertical plate assembly 3″ cooperate to form a lattice structure 4 composed of three first transverse plates 2a, three second transverse plates 2b and ten vertical plates 3. In the lattice structure 4, the gaps and openings 2a between the boards constituting the cross board assemblies 2', the first vertical board assemblies 3', and the second vertical board assemblies 3″ pass through 1 、2b 1 、3a 1 、3b 1 A curved air passage is formed.
The lattice structure 4 is housed in a case 5 formed of cardboard such as cardboard, thick paper, corrugated paper, or the like, and constitutes the paint mist collecting device 1. The inlet opening 5a and the outlet opening 5b formed in the opposite side surfaces of the case 5 are respectively opposed to the elongated openings 2a1 and 2b1 of the lattice structure 4.
The surfaces of the first and second cross plates 2a, 2b facing the inlet opening 5a, the two surfaces of the vertical plate 3, and the inner surface of the case 5 are subjected to surface treatment for improving the paint mist collecting efficiency. Specifically, the surface roughness increasing treatment is performed by attaching a low internal density sheet such as a nonwoven fabric or a bulky paper including a cotton paper, or by applying an anti-slip coating material or a foaming coating material, roughening using a needle, sandpaper or a grinding machine, roughening using sandblasting, or the like.
Dry nonwoven fabrics, particularly air-laid (air-laid) nonwoven fabrics, are preferred because they are low internal density sheets that contain many voids that trap coating mist.
The operation and effects of the paint mist collecting device 1 will be described.
The paint mist collecting device 1 is disposed in a straight line advancing portion of the spray booth exhaust path.
The exhaust gas of the not-shown spray booth flows into the case 5 through the inlet opening 5a, and further flows into the lattice structure 4 as an exhaust gas flow shown by a blank arrow in fig. 1, and as shown in fig. 7, flows out of the case 5 through the outlet opening 5b through a curved air passage formed by gaps between the boards constituting the horizontal board assembly 2', the first vertical board assembly 3', and the second vertical board assembly 3″ and the openings 2a1, 2b1, 3a1, 3b 1. When passing through the curved air passage, the exhaust gas from the spray booth collides with the portions sandwiched between the openings 2a1 and 2b1 of the cross plates 2a and 2b or the portions sandwiched between the openings 3a1 and 3b1 of the vertical plates 3a and 3b, and the paint mist adheres to the portions and is trapped. The exhaust gas of the spray booth from which the paint mist is removed flows out from the paint mist collecting device 1.
In the paint mist collecting device 1, the slits are aligned with each other, and the vertical plates 3a and 3b having the openings 3a1 and 3b1 and the slits 3a2 and 3b2 are inserted into the horizontal plates 2a and 2b having the openings 2a1 and 2b1 and the slits 2a2 and 2b2, so that the paint mist collecting device is formed without a complicated bending process.
Since the spray booth exhaust gas passes through the curved air passage, the number of collisions between the spray booth exhaust gas and the cross plates 2a, 2b and the vertical plates 3a, 3b increases, and the paint mist collection efficiency increases.
Since the openings 2a1, 2b1, 3a1, 3b1 are elongated, the structure of the cross plates 2a, 2b and the vertical plates 3a, 3b is simplified, the air resistance is reduced, and the mist collection efficiency is improved, as compared with the case where a plurality of small openings are provided in alignment.
As shown in fig. 1, the interval between the first and second cross plates 2a, 2b decreases from one end face of the cross plate aggregate 2' opposite to the inlet opening 5a of the case 5 toward the other end face opposite to the outlet opening 5b of the case 5, more specifically, from the upstream side toward the downstream side with respect to the spray booth exhaust flow shown by the blank arrow in fig. 1. If the paint mist collecting device 1 is arranged such that the exhaust gas of the spray booth flows from the one end face toward the other end face of the cross plate aggregate 2', a large amount of paint mist is collected at the upstream portion of the curved air passage formed by the cross plate aggregate 2', the first vertical plate aggregate 3', and the second vertical plate aggregate 3″ and the amount of mist collected as it goes downstream decreases. Since the trapped paint mist is accumulated in the space between the adjacent first and second cross plates 2a, 2b, it is reasonable to decrease the interval between the first and second cross plates 2a, 2b from one end face to the other end face of the cross plate aggregate 2'.
Since the vertical plate assembly formed of ten vertical plates 3 is divided into the first portion 3' inserted into the horizontal plate assembly 2' from one end side of the elongated openings 2a1, 2b1 of the horizontal plates and the second portion 3″ inserted into the horizontal plate assembly 2' from the other end side of the elongated openings 2a1, 2b1 of the horizontal plates, the sliding resistance at the time of insertion is reduced, and the assembling operation of the lattice structure 4 is facilitated.
The surfaces of the first and second cross plates 2a and 2b facing the inlet opening 5a, the two surfaces of the vertical plate 3, and the inner surface of the case 5 are subjected to an adsorption force increasing treatment by adhesion of a low internal density sheet such as a nonwoven fabric or a bulky paper including a cotton paper, or a surface roughness increasing treatment by application of an anti-slip paint or a foaming paint, roughening by a needle, a sand paper or a grinding machine, roughening by sand blasting, or the like, whereby the paint mist collecting efficiency is improved.
The lattice structure 4 in which the vertical plate aggregate composed of the first portion 3 'and the second portion 3″ is inserted into the horizontal plate aggregate 2' has no fastening portion such as adhesion, and therefore can be easily folded as shown in fig. 8 (a) and (b), and can be easily restored to a three-dimensional structure from the folded state. By folding the lattice structure 4 and the case 5, the paint mist collecting device 1 can be easily transported.
The paint mist collecting device 1 made of cardboard such as cardboard, thick paper, corrugated paper, etc. is light, and thus is easy to transport and easy to handle after use.
An appropriate plate filter 6 as shown in fig. 9 may be disposed in the case 5 adjacent to the cross plate 2b forming the downstream end face with respect to the spray booth exhaust flow of the cross plate aggregate 2'.
The filter 6 is disposed in addition to the lattice structure, and the paint mist collecting efficiency is improved.
In the case where the paint mist collecting device 1 is disposed in the straight-line advancing portion of the spray booth exhaust path, it is reasonable that the inlet opening 5a and the outlet opening 5b are formed in the wall surfaces of the case 5 that face each other. However, it is difficult to provide the paint mist collecting device 1, in which the inlet opening 5a and the outlet opening 5b are formed in the wall surfaces of the case 5 facing each other, at the curved portion of the spray booth exhaust path so as to perform the intended function.
As shown in fig. 10 and 11, if the paint mist collecting device 1 includes the inlet opening 5a and the outlet opening 5b orthogonal to each other, it can be provided in a curved portion of the spray booth exhaust path to perform a desired function.
In the embodiment shown in fig. 10, the inlet opening 5a is formed in one of the pair of wall surfaces of the case 5 opposed to the opening of the cross plate, specifically, the outlet opening 5b is formed in the wall surface opposed to the opening of the second cross plate 2b, and the inlet opening 5a is disposed close to the other of the pair of wall surfaces of the case 5 opposed to the opening of the cross plate, specifically, the wall surface opposed to the opening of the first cross plate 2a, in one of the pair of wall surfaces of the case 5 opposed to the lattice shape of the lattice structure 4.
If the lattice structure 4 is opposed to the inlet opening 5a, the spray booth exhaust gas flowing into the lattice structure 4 through the inlet opening 5a toward the lattice shape collides with the spray booth exhaust gas flowing in parallel with the lattice shape in the lattice structure toward the outlet opening 5b, and the airflow in the lattice structure 4 is disturbed, and there is a possibility that the paint mist collecting efficiency is lowered. Therefore, it is desirable that the lattice structure 4 is not opposed to the inlet opening 5 a. On the other hand, in order to position the lattice structure 4 in the case 5, it is desirable that the vertical plate 3 extends from one of the pair of wall surfaces of the case 5 opposed to the transverse plate of the lattice structure 4, specifically, the wall surface formed with the outlet opening 5b, to the other of the pair of wall surfaces of the case 5 opposed to the transverse plate of the lattice structure 4, specifically, the wall surface opposed to the first transverse plate 2 a. If the vertical plate 3 is extended from the lattice structure 4, the vertical plate 3 can be extended from one of the pair of wall surfaces of the case facing the transverse plate of the lattice structure 4 to the other. In this case, as shown in fig. 10 (b), the extension portion 3c of the vertical plate shown by the one-dot chain line becomes opposed to the inlet opening 5a shown by the three-dot chain line.
Since the extension portion 3c of the vertical plate is not formed in the lattice structure 4 having the curved air passage formed therein, an opening is not necessary. Thus, the extension 3c serves as a plate body without an opening.
The operation and effects of the paint mist collecting device 1 shown in fig. 10 will be described.
The paint mist collecting device 1 is disposed at a curved portion of the exhaust path of the spray booth.
The exhaust gas of the not-shown spray booth flows into the case 5 through the inlet opening 5a as indicated by the blank arrow in fig. 10 (a), and in the exhaust flow path between the adjacent vertical plate extensions 3c, the streamline is bent by 90 degrees as indicated by the blank arrow in fig. 1 (a), the exhaust gas flow toward the first horizontal plate 2a is formed to flow into the lattice structure 4, and as indicated by fig. 7, the curved air passage formed by the gaps between the cardboard plates constituting the horizontal plate aggregate 2', the first vertical plate aggregate 3', the second vertical plate aggregate 3″ and the openings 2a1, 2b1, 3a1, 3b1 proceeds straight as indicated by the blank arrow in fig. 10 (a), and flows out of the case 5 through the outlet opening 5b. When passing through the curved air passage, the exhaust gas from the spray booth collides with the portions sandwiched between the openings 2a1 and 2b1 of the cross plates 2a and 2b or the portions sandwiched between the openings 3a1 and 3b1 of the vertical plates 3a and 3b, and the paint mist adheres to the portions and is trapped. The exhaust gas of the spray booth from which the paint mist is removed is discharged from the paint mist collecting device 1.
The paint mist collecting device 1 does not need the driving power of the circulating water pump, and therefore can achieve energy saving as compared with the conventional wet paint mist collecting device.
In the paint mist collecting device 1, the slits are aligned with each other, and the vertical plates 3a and 3b having the openings 3a1 and 3b1 and the slits 3a2 and 3b2 are inserted into the horizontal plates 2a and 2b having the openings 2a1 and 2b1 and the slits 2a2 and 2b2, so that the paint mist collecting device is formed without a complicated bending process.
Since the spray booth exhaust gas passes through the curved air passage, the number of collisions between the spray booth exhaust gas and the cross plates 2a, 2b and the vertical plates 3a, 3b increases, and the paint mist collection efficiency increases.
The paint mist collecting device 1 includes an inlet opening 5a and an outlet opening 5b that are orthogonal to each other, and thus can be provided in a curved portion of the spray booth exhaust path.
If the vertical plate 3 is extended from the lattice structure 4, the aggregate of the extension portions 3c does not form a lattice structure, and the strength is lowered. As shown in fig. 11 (b), the second cross plate 2b shown by the two-dot chain line is arranged in the aggregate of the vertical plate extension portions 3c shown by the one-dot chain line, and the lattice structure 4 having the curved air passage formed therein is expanded, so that the strength of the aggregate of the vertical plate extension portions 3c can be prevented from being lowered. As a result, as shown in fig. 11 (b), a part of the lattice structure 4 faces the inlet opening 5a shown by the three-dot chain line, but when the extension of the vertical plate 3 is increased in size according to the size of the inlet opening 5a, a need may arise to dispose the horizontal plate on the aggregate of the vertical plate extension 3 c. In this case, the opening is formed in the vertical plate extension portion 3c included in the expanded portion of the lattice structure 4, but the vertical plate extension portion 3c extending from the expanded lattice structure 4 is not formed in the lattice structure 4 in which the curved air passage is formed, and thus the opening is not required.
The lattice structure 4 shown in fig. 1 (a) may be accommodated in the case 5 shown in fig. 1 (b) in which the inlet opening 5a and the outlet opening 5b are formed in the pair of opposed wall surfaces, and as shown in fig. 12, the hollow cover 7 may be attached to the end of the case 5 in which the inlet opening 5a is formed, and the inlet opening 7a communicating with the inlet opening 5a of the case 5 may be formed in the side surface of the cover 7.
In the paint mist collecting device 1 having the above-described configuration, as shown by the blank arrow in fig. 12, the spray booth exhaust gas flows into the lattice structure 4 through the opening 7a of the lid body 7 and the inlet opening 5a of the case 5, flows through the curved air passage in the lattice structure 4, and flows out of the case 5 through the outlet opening 5b. The inlet opening 7a of the cover 7 is orthogonal to the outlet opening 5b of the case 5, so that the paint mist collecting device 1 having the above-described configuration can be provided in a curved portion of the spray booth exhaust path.
By fitting the cover 7 to the outside of the end portion of the case 5 where the inlet opening 5a is formed, the cover 7 can be easily attached to the case 5.
The embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments. For example, the number of blocks or aspect ratio of the transverse plates and the longitudinal plates constituting the lattice structure 4 is not limited to the case of the above embodiment.
