Description

本発明は塗装ブースに配設される塗料ミスト捕集装置に関するものである。 The present invention relates to a paint mist collecting device arranged in a coating booth.

例えば文献１に開示されているように、塗装ブースから吸引した排気を水と共にベンチュリーに導き、ベンチュリーで霧化した水の微粒子で排気中に含まれる塗料ミストを捕捉する湿式の塗料ミスト捕集装置が従来から広く使用されている。
湿式の塗料ミスト捕集装置に対し、板部材に排気を衝突させて塗料ミストを捕捉する乾式の塗料ミスト捕集装置が近年使用されるようになった。乾式の塗料ミスト捕集装置は、循環水ポンプの駆動電力を必要としない点で、従来の湿式塗料ミスト捕集装置に比べて省エネを実現できるという利点がある。
特許文献２は、多数の開口が形成された板部材を複雑に折り曲げて形成した乾式の塗料ミスト捕集装置を開示している。 For example, as disclosed in Document 1, a wet paint mist collecting device that guides exhaust gas sucked from a coating booth together with water to a venturi and collects paint mist contained in the exhaust gas with fine particles of water atomized by the venturi. Has been widely used.
In contrast to a wet type paint mist collecting device, a dry type paint mist collecting device has recently been used, in which exhaust gas is collided with a plate member to catch the paint mist. The dry type paint mist collecting device has an advantage that energy saving can be realized as compared with the conventional wet type paint mist collecting device in that it does not require driving power for the circulating water pump.
Patent Document 2 discloses a dry paint mist collecting device which is formed by complicatedly bending a plate member having a large number of openings.

特許文献２の複雑に折り曲げて形成する乾式の塗料ミスト捕集装置には、折り曲げの手順や方向を間違えると所期の形状が得られないという問題がある。また、対向する板部材の開口が正対しているので、塗装ブース排気と板部材との衝突回数が少なく塗料ミスト捕集効率が悪いという問題もある。
本発明は板部材で構成された乾式の塗料ミスト捕集装置であって、複雑な折り曲げ工程を経ることなく構成された、且つ塗料ミスト捕集効率の高い、塗料ミスト捕集装置を提供することを目的とする。 The dry paint mist collecting device of Patent Document 2 that is formed by bending in a complicated manner has a problem that the desired shape cannot be obtained if the bending procedure and direction are incorrect. Further, since the openings of the plate members facing each other face each other, there is a problem that the number of collisions between the exhaust of the coating booth and the plate member is small and the paint mist collecting efficiency is poor.
The present invention provides a dry paint mist collecting device composed of a plate member, which is configured without a complicated bending step and has a high paint mist collecting efficiency. With the goal.

上記課題を解決するために、本発明においては、複数の細長開口と前記各細長開口を間に挟んで周縁から前記細長開口の長手方向延在長の途中まで延在する複数のスリットとが形成された複数の第１横板と、複数の細長開口と前記各細長開口を間に挟んで周縁から前記細長開口の長手方向延在長の途中まで延在する複数のスリットとが形成された複数の第２横板と、複数の細長開口と前記各細長開口を間に挟んで周縁から前記細長開口の長手方向延在長の途中まで延在する複数のスリットとが形成された複数の縦板とを備え、第１横板と第２横板とが隙間を隔てて交互に配設されて横板集合体を形成し、横板集合体内において第２横板の隣接する細長開口の間の部位が第１横板の細長開口に対峙すると共に第２横板の細長開口が第１横板の隣接する細長開口の間の部位に対峙し、複数の縦板が隙間を隔てて配設されて縦板集合体を形成し、縦板集合体が自身のスリットを横板集合体のスリットに整列させて横板集合体に差し込まれ、横板集合体と縦板集合体とが協働して格子構造体を形成し、格子構造体内に屈曲した空気通路が形成され、前記格子構造体が横板の細長開口に対峙する開口が形成された箱体に収納されていることを特徴とする塗料ミスト捕集装置を提供する。
開口とスリットとが形成された複数の横板で構成された横板集合体に、開口とスリットとが形成された複数の縦板で構成された縦板集合体が、互いのスリットを整列させて差し込まれた塗料ミスト捕集装置は、複雑な折り曲げ工程を経ることなく構成されている。
格子構造体内に屈曲した空気通路が形成されているので、塗装ブース排気は屈曲した空気通路を通過する。この結果、塗装ブース排気と横板、縦板との衝突回数が増加し、塗料ミスト捕集効率が向上する。 In order to solve the above-mentioned problems, in the present invention, a plurality of elongated openings and a plurality of slits extending from the peripheral edge to the middle of the longitudinal extension length of the elongated openings with the respective elongated openings sandwiched therebetween are formed. A plurality of first lateral plates, and a plurality of slits extending from the peripheral edge to the middle of the lengthwise extending length of the elongated openings with the plurality of elongated openings and each of the elongated openings sandwiched therebetween. And a plurality of vertical plates having a plurality of elongated openings and a plurality of slits extending from the peripheral edge to the middle of the lengthwise extending length of the elongated openings with the elongated openings interposed therebetween. And a first horizontal plate and a second horizontal plate are alternately arranged with a gap therebetween to form a horizontal plate assembly, and between the adjacent elongated openings of the second horizontal plate in the horizontal plate assembly. The portion faces the elongated opening of the first horizontal plate, the elongated opening of the second horizontal plate faces the portion between the adjacent elongated openings of the first horizontal plate, and a plurality of vertical plates are arranged with a gap therebetween. To form a vertical plate assembly, the vertical plate assembly aligns its slit with the slits of the horizontal plate assembly and is inserted into the horizontal plate assembly, and the horizontal plate assembly and the vertical plate assembly cooperate with each other. Forming a lattice structure, a bent air passage is formed in the lattice structure, and the lattice structure is housed in a box body having an opening facing the elongated opening of the horizontal plate. A paint mist collecting device is provided.
A horizontal plate assembly composed of a plurality of horizontal plates in which openings and slits are formed, a vertical plate assembly composed of a plurality of vertical plates in which openings and slits are formed, aligning the slits of each other. The paint mist collecting device that is inserted as described above is configured without a complicated bending process.
Since the curved air passage is formed in the lattice structure, the paint booth exhaust gas passes through the curved air passage. As a result, the number of collisions between the exhaust of the coating booth and the horizontal and vertical plates increases, and the paint mist collection efficiency improves.

本発明の好ましい態様においては、第１横板と第２横板との間隔が、横板集合体の一方の端面から他方の端面に向けて減少している。
横板集合体の前記一方の端面から他方の端面へ向けて塗装ブースの排気が流れるように塗料ミスト捕集装置を配設すると、横板集合体と縦板集合体とで形成される屈曲した空気通路の上流部で多量の塗料ミストが捕集され、下流へ行くに従って捕集されるミストの量は減少する。捕集された塗料ミストは隣接する第１横板と第２横板との間の空間に溜まるので、第１横板と第２横板との間隔は、横板集合体の一方の端面から他方の端面に向けて減少させるのが合理的である。
本発明の好ましい態様においては、箱体内に且つ横板集合体の他方の端面に隣接してフィルターが配設されている。
格子構造体に加えてフィルターを配設することにより、塗料ミスト捕集効率が向上する。
本発明の好ましい態様においては、縦板集合体は横板の細長開口の一方の端部側から横板集合体に差し込まれる第１部分と、横板の細長開口の他方の端部側から横板集合体に差し込まれる第２部分とで構成されている。
縦板集合体を、横板の細長開口の一方の端部側から横板集合体に差し込まれる第１部分と、横板の細長開口の他方の端部側から横板集合体に差し込まれる第２部分とに分けることにより、差し込む際の摺動抵抗が減少し、格子構造体の組み付け作業が容易になる。
本発明の好ましい態様においては、横板集合体と縦板集合体とが協働して形成する格子構造体は、折り畳み可能である。
縦板集合体が横板集合体に差し込まれた格子構造体は、接着等の固着部がないので、容易に折り畳むことができ、また折り畳んだ状態から立体構造に容易に復元できる。折り畳むことにより、塗料ミスト捕集装置の搬送が容易になる。
本発明の好ましい態様においては、第１横板と第２横板と縦板と箱体とは板紙で形成されている。
ボール紙、厚紙、ダンボール紙等の板紙で構成した塗料ミスト捕集装置は軽いので搬送が容易であり、また使用後の処理が容易である。 In a preferred aspect of the present invention, the distance between the first horizontal plate and the second horizontal plate decreases from one end surface of the horizontal plate assembly toward the other end surface.
When the paint mist collecting device is arranged so that the exhaust air of the coating booth flows from the one end surface of the horizontal plate assembly toward the other end surface, the bent plate formed by the horizontal plate assembly and the vertical plate assembly is bent. A large amount of paint mist is collected in the upstream part of the air passage, and the amount of collected mist decreases as it goes downstream. Since the collected paint mist collects in the space between the adjacent first horizontal plate and second horizontal plate, the distance between the first horizontal plate and the second horizontal plate is set from one end face of the horizontal plate assembly. It is rational to decrease toward the other end face.
In a preferred aspect of the present invention, the filter is arranged inside the box and adjacent to the other end surface of the lateral plate assembly.
By disposing the filter in addition to the lattice structure, the paint mist collecting efficiency is improved.
In a preferred embodiment of the present invention, the vertical plate assembly comprises a first portion inserted into the horizontal plate assembly from one end side of the elongated opening of the horizontal plate and a horizontal portion from the other end side of the elongated opening of the horizontal plate. And a second portion to be inserted into the plate assembly.
The vertical plate assembly is inserted into the horizontal plate assembly from one end side of the elongated opening of the horizontal plate, and the first part is inserted into the horizontal plate assembly from the other end side of the elongated opening of the horizontal plate. By dividing into two parts, the sliding resistance at the time of insertion is reduced, and the assembling work of the lattice structure becomes easy.
In a preferred embodiment of the present invention, the lattice structure formed by the horizontal plate assembly and the vertical plate assembly in cooperation is foldable.
The lattice structure in which the vertical plate assembly is inserted into the horizontal plate assembly does not have a fixed portion such as an adhesive, and thus can be easily folded and can be easily restored from the folded state to a three-dimensional structure. Folding facilitates transport of the paint mist collecting device.
In a preferred aspect of the present invention, the first horizontal plate, the second horizontal plate, the vertical plate, and the box body are made of paperboard.
The paint mist collecting device made of paperboard such as cardboard, cardboard, cardboard, etc., is light in weight, so that it can be easily transported and processed after use.

塗料ミスト捕集装置１の作動と作用効果とを説明する。
図示しない塗装ブースの排気が、一方の開口５ａを通って箱体５へ流入し、更に図１に白抜き矢印で示す排気流を形成して格子構造体４に流入し、図７に示すように、横板集合体２’、第1縦板集合体３’、第２縦板集合体３”を構成する板紙間の隙間と開口２ａ_１、２ｂ_１、３ａ_１、３ｂ_１とが形成する屈曲した空気通路を通過し、他方の開口５ｂを通って箱体５から流出する。前記屈曲した空気通路を通過する際に、横板２ａ、２ｂの開口２ａ_１、２ｂ_１に挟まれた部位や、縦板３ａ、３ｂの開口３ａ_１、３ｂ_１に挟まれた部位に塗装ブースの排気が衝突し、前記部位に塗料ミストが付着して、塗料ミストが捕集される。塗料ミストが除去された塗装ブースの排気が塗料ミスト捕集装置１から排出される。
塗料ミスト捕集装置１においては、開口２ａ_１、２ｂ_１とスリット２ａ_２、２ｂ_２とが形成された横板２ａ、２ｂに開口３ａ_１、３ｂ_１とスリット３ａ_２、３ｂ_２とが形成された縦板３ａ、３ｂを、互いのスリットを整列させて差し込むことにより、複雑な折り曲げ工程を経ることなく塗料ミスト捕集装置が構成されている。
塗装ブース排気が屈曲した空気通路を通過するので、塗装ブース排気と横板２ａ、２ｂ、縦板３ａ、３ｂとの衝突回数が増加し、塗料ミスト捕集効率が向上している。
開口２ａ_１、２ｂ_１、３ａ_１、３ｂ_１を細長開口としたので、小開口を整列して複数設ける場合に比べて横板２ａ、２ｂ、縦板３ａ、３ｂの構成が簡素化されると共に、空気抵抗が低減してミスト捕集効率が向上している。 The operation and effect of the paint mist collecting device 1 will be described.
Exhaust gas from a paint booth (not shown) flows into the box body 5 through one opening 5a, further forms an exhaust flow indicated by a white arrow in FIG. 1 and flows into the lattice structure 4, and as shown in FIG. And the openings 2a ₁ , 2b ₁ , 3a ₁ , 3b ₁ are formed between the paperboards that form the horizontal plate assembly 2′, the first vertical plate assembly 3′, and the second vertical plate assembly 3″. It passes through the curved air passage and flows out from the box body 5 through the other opening 5b. A portion sandwiched between the openings 2a ₁ and 2b ₁ of the horizontal plates 2a and 2b when passing through the curved air passage. Alternatively, the exhaust gas of the coating booth collides with the portion sandwiched between the openings 3a ₁ and 3b ₁ of the vertical plates 3a and 3b, and the paint mist adheres to the portion and the paint mist is collected. The exhaust air of the coating booth is discharged from the paint mist collecting device 1.
In the paint mist collecting device 1, openings 3a ₁ , 3b ₁ and slits 3a ₂ , 3b ₂ are formed in the horizontal plates 2a, 2b having openings 2a ₁ , 2b ₁ and slits 2a ₂ , 2b _2. By inserting the vertical plates 3a and 3b with their slits aligned, the paint mist collecting device is configured without a complicated bending process.
Since the coating booth exhaust passes through the curved air passage, the number of collisions between the coating booth exhaust and the horizontal plates 2a, 2b and the vertical plates 3a, 3b is increased, and the paint mist collecting efficiency is improved.
Since the openings 2a ₁ , 2b _1, 3a ₁ , 3b ₁ are elongated openings, the configurations of the horizontal plates 2a, 2b and the vertical plates 3a, 3b are simplified as compared with the case where a plurality of small openings are aligned and provided. , Air resistance is reduced and mist collection efficiency is improved.

図１に示すように、第１横板２ａと第２横板２ｂとの間隔は、横板集合体２’の一方の端面から他方の端面に向けて、より具体的には図１に白抜き矢印で示す塗装ブース排気の流れに関して上流側から下流側へ向けて、減少している。横板集合体２’の前記一方の端面から他方の端面へ向けて塗装ブースの排気が流れるように塗料ミスト捕集装置１を配設すると、横板集合体２’と第１縦板集合体３’と第２縦板集合体３”とで形成される屈曲した空気通路の上流部で多量の塗料ミストが捕集され、下流へ行くに従って捕集されるミストの量は減少する。捕集された塗料ミストは隣接する第１横板２ａと第２横板２ｂとの間の空間に溜まるので、第１横板２ａと第２横板２ｂとの間隔は、横板集合体２’の一方の端面から他方の端面に向けて減少させるのが合理的である。
１０枚の縦板３で形成される縦板集合体を、横板の細長開口２ａ_１、２ｂ_１の一方の端部側から横板集合体２’に差し込まれる第１部分３’と、横板の細長開口２ａ_１、２ｂ_１の他方の端部側から横板集合体２’に差し込まれる第２部分３”とに分けたので、差し込む際の摺動抵抗が減少し、格子構造４体の組み付け作業が容易になっている。
第１部分３’と第２部分３”とで構成される縦板集合体が横板集合体２’に差し込まれた格子構造体４は、接着等の固着部がないので、図８（a）、（b）に示すように、容易に折り畳むことができ、また折り畳んだ状態から立体構造に容易に復元できる。格子構造体４と箱体５とを折り畳むことにより、塗料ミスト捕集装置１の搬送が容易になる。
ボール紙、厚紙、ダンボール紙等の板紙で構成した塗料ミスト捕集装置１は軽いので搬送が容易であり、また使用後の処理が容易である。
図９に示すような、適当な板状のフィルター６を、箱体５内に且つ横板集合体２’の塗装ブース排気流に関して下流側端面を形成する横板２ｂに隣接して、配設しても良い。
格子構造体に加えてフィルター６を配設することにより、塗料ミスト捕集効率が向上する。 As shown in FIG. 1, the distance between the first horizontal plate 2a and the second horizontal plate 2b is from the one end face of the horizontal plate assembly 2'to the other end face, more specifically, in FIG. With respect to the flow of the paint booth exhaust indicated by the hollow arrow, it decreases from the upstream side to the downstream side. When the paint mist collecting device 1 is arranged so that the exhaust air from the coating booth flows from the one end face of the horizontal plate assembly 2'to the other end face, the horizontal plate assembly 2'and the first vertical plate assembly A large amount of paint mist is collected in the upstream part of the curved air passage formed by 3'and the second vertical plate assembly 3'', and the amount of mist collected decreases as it goes downstream. The paint mist thus collected accumulates in the space between the adjacent first horizontal plate 2a and second horizontal plate 2b, so that the distance between the first horizontal plate 2a and the second horizontal plate 2b is equal to that of the horizontal plate assembly 2'. It is rational to decrease from one end face to the other end face.
A vertical plate assembly formed by ten vertical plates 3 is inserted into the horizontal plate assembly 2'from _one end side of the elongated openings 2a ₁ and 2b ₁ of the horizontal plate, and a horizontal portion Since the other side of the elongated openings 2a ₁ and 2b ₁ of the plate is divided into the second portion 3″ to be inserted into the lateral plate assembly 2′, the sliding resistance at the time of insertion is reduced, and the lattice structure 4 body is formed. Assembly work is easy.
Since the lattice structure 4 in which the vertical plate assembly composed of the first portion 3′ and the second portion 3″ is inserted into the horizontal plate assembly 2′ does not have a fixed portion such as an adhesive, FIG. ) And (b), it can be easily folded, and can be easily restored to a three-dimensional structure from the folded state by folding the lattice structure 4 and the box body 5. Is easy to carry.
The paint mist collecting device 1 made of paperboard such as cardboard, cardboard, cardboard, etc. is light and therefore easy to transport and easy to process after use.
A suitable plate-shaped filter 6 as shown in FIG. 9 is disposed inside the box 5 and adjacent to the horizontal plate 2b forming the downstream end face with respect to the exhaust flow of the coating booth of the horizontal plate assembly 2'. You may do it.
By disposing the filter 6 in addition to the lattice structure, the paint mist collecting efficiency is improved.
