Description

Adjustable dry type spraying room lime powder and stirring device

Technical field

The utility model relates to paint spraying apparatus technical fields, fill in particular to a kind of adjustable dry type spraying room lime powder and stirring It sets.

Background technique

Dry type spraying room is as new technology more popular in recent years, relative to traditional wet paint spray booth, in energy consumption and There is significant advantage in terms of the generation of pollution sources.One of dry type spraying room is adsorbed in paint spray booth using lime powder as carrier Over-sprayed paint fog, pulverized limestone is purged into material bin mixing chamber by pressure-air, and over-sprayed paint fog is transported to by exhaust system It is mixed in hopper mixing chamber and with pulverized limestone, fixed mixture and air is then separated by leaf filter again, it is generated Spent lime can be used for cement manufacture, be effectively reduced the generation of waste water and dregs.But the dosage of pulverized limestone it is excessively high and it is high at This private filter updating maintenance expense becomes the new problem for restricting its application, and the deposition for reducing paint slag can make to paint slag in stone Ashes surface is uniformly distributed, and is effectively reduced pulverized limestone dosage and is extended the service life of filter.

Utility model content

The purpose of this utility model seeks to overcome above-mentioned the shortcomings of the prior art, provides a kind of mixed with over-sprayed paint fog Close adjustable spray room lime powder and stirring device that is uniform, preventing coating cloud from agglomerating.

To achieve the above object, the utility model provides a kind of adjustable dry type spraying room lime powder and stirring device, including material Struggle against mixing chamber, and feed inlet and compressed-air atomizer are equipped at the top of the hopper mixing chamber, and hopper mixing chamber bottom is equipped with Material mouth, it is characterised in that: further include shaft and blade, the both ends of the shaft and hopper mixing chamber side wall are rotatablely connected, the leaf Piece is detachably connected with shaft, is staggered certain angle between the adjacent blades in sagittal plane.

Further, the blade bottom two sides are equipped with convex block, and the convex block is removable by positioning pin and blade mounting base Unload connection.

Further, the blade mounting base is U-shaped board, and the U-shaped board two sides are provided with bolt hole, the U-shaped board with turn Axis engages and is bolted to connection.

Further, the blade is symmetrical with the midpoint of shaft, and multiple blades are distributed in shaft midpoint two sides Group, the blade group are made of adjacent three blades, and the angle in the blade group between adjacent blades is respectively 120 °, 90 °.

The beneficial effects of the utility model are: increasing a shaft with blade at the middle part of hopper mixing chamber, by outer Driving device drive shaft band movable vane piece in portion rotates, the angle on sagittal plane between adjacent blades be respectively 120 °, 90 ° and 150 °, blade forms the turbulent air flow irregularly flowed when rotating, so that pulverized limestone mixes more uniform with over-sprayed paint fog, prevents Over-sprayed paint fog agglomerates because the pulverized limestone of absorption is less, extends the service life of filter.

Detailed description of the invention

Fig. 1 is lime powder and stirring apparatus structure main view.

Fig. 2 is blade and rotating shaft connecting structure side view.

Fig. 3 is single blade structural schematic diagram.

Each part numbers are as follows in figure: hopper mixing chamber 1, feed inlet 11, compressed-air atomizer 12, discharge port 13, shaft 2, bearing 3, blade group 4, blade mounting base 5, bolt hole 51, blade 40, convex block 41, positioning pin 42.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing, convenient for more clearly understanding that this is practical new Type, but they do not constitute the utility model and limit.

As shown in Figures 1 to 3, a kind of adjustable dry type spraying room lime powder and stirring device, including hopper mixing chamber 1, hopper are mixed It closes and is equipped with feed inlet 11 and compressed-air atomizer 12 at the top of room 1, it further includes shaft 2 that 1 bottom of hopper mixing chamber, which is equipped with discharge port 13, With blade 40,2 both ends of shaft are fixedly connected with 3 inner ring of bearing, and 3 outer ring of bearing is fixedly connected with 1 side wall of hopper mixing chamber, blade 40 two sides of the bottom are equipped with convex block 41, and convex block 41 is detachably connected by positioning pin 42 with blade mounting base 5, blade 4 and shaft 2 it Between angle can be adjusted by positioning pin 42, blade mounting base 5 be U-shaped board, U-shaped board two sides are provided with bolt hole 51, U-shaped board Engage with shaft 2, blade mounting base 5 is bolted to connection with shaft 2.

In above-mentioned technical proposal, blade 40 is symmetrical with the midpoint of shaft 2, the nearest leaf 40 in 2 midpoint two sides of shaft it Between angle be 0 °, 2 midpoint two sides of shaft are respectively equipped with two blade groups 4, and each blade group 4 is by three adjacent 40 structures of blade At, the angle in blade group 4 between adjacent blades 40 is 120 °, 90 °, in this way since left end, first blade and second A leaf angle is 120, and second blade and third leaf angle are 90, and third blade is with the quaterfoil angle 150, it repeats according to this.

Current hopper mixing chamber 1 pressure-air that only pneumatically nozzle spray 12 goes out will be flowed into from feed inlet 11 Pulverized limestone dispels each space of hopper mixing chamber 1, and since high pressure draught velocity flow profile is uneven, pulverized limestone is in hopper mixing chamber Distribution in 1 is also uneven, paints slag agglomeration easy to form.Increase agitating device on this basis, is turned by external motor driving Axis 2 is rotated with movable vane piece 40, simultaneously because the structure distribution of blade 40 is irregular, the pulverized limestone flowed into is mixed in hopper It closes in room 1 and forms turbulent flow, pulverized limestone is more evenly distributed in each space of hopper mixing chamber 1, so that over-sprayed paint fog Pulverized limestone is equably adsorbed, the viscosity of over-sprayed paint fog is reduced, is not easy to agglomerate because of viscosity between coating cloud particle, has served as painting Mist can not be swum in hopper mixing chamber 1 after absorbing enough pulverized limestones because particle becomes larger, and just fall to hopper mixing The bottom of room 1, and be discharged from discharge port 13.
