A kind of cascade water-spinning spray chamber
Technical field
The invention belongs to coating equipment technical field, be specifically related to a kind of paint spray booth that there is cascade water and revolve.
Background technology
When spraying paint process to workpiece, have the spray of part paint less than on workpiece, paint can fill the air in indoor, if do not processed this part paint, can permeate in air, contaminated environment, damages the healthy of workman of spraying paint.
Processing mode at present for pollution of spraying paint digs a hollow place in spray booth underground, and will be harmful to outside paint discharge chamber by vent passages, this mode can cause severe contamination to environment.
Being restricted to certain region by water curtain by spraying paint in addition, then passing through to filter, this method compares and is difficult to hold in practical operation, and removal efficiency is not high.
Summary of the invention
The object of the present invention is to provide a kind of cascade water-spinning spray chamber.This paint spray booth can be efficient, the coating cloud produced in the removal painting process of environmental protection.
A kind of cascade water-spinning spray chamber, primary filter cotton 3 is set between dynamic pressure case 1 and plenum chamber 2, sub-high efficiency filter floor 4 is set between plenum chamber 2 and spraying operation room 11, spraying operation room 11 is provided with spraying workpiece 5, the sidewall of spraying operation room 11 is provided with the first water curtain 6, and spraying workpiece 5 bottom is provided with tank 7, and the bottom periphery of tank 7 is provided with the second water curtain 8, the bottom of tank 7 is provided with water spigot 12, and water spigot 12 is connected with exhaust blower 9 by air draft passage 10.
The material of described first water curtain 6 and the second water curtain 8 is stainless steel.
Described primary filter cotton is synthetic fibers filter cotton, non-woven fabrics filter cotton.
Flocculant is added with in the water of described tank 7.
Described flocculant is the material composition of following portions by weight: polyacrylamide 30-40 part, aluminum sodium sulfate 25-40 part, sodium carbonate 10-30 part, sodium metaaluminate 1-5 part and plant polyphenol 1-5 part.
Described plant polyphenol is vine polyphenol, apple polyphenol or Tea Polyphenols.
The stage casing of described air draft passage 10 is provided with water fender 13.
Beneficial effect of the present invention: cascade water-spinning spray chamber of the present invention can be efficient, the coating cloud produced in the removal painting process of environmental protection.Be provided with the effect that primarily efficient filter wool plays current-sharing air between dynamic pressure room and plenum chamber, between plenum chamber and paint spraying room, be provided with sub-high efficiency filter floor, ensure the cleanliness factor entering indoor air, make the air-flow sent here in operation room simultaneously evenly.Be added with efficient flocculant in the water of tank, make paint drop onto with regard to phase inter coagulation in water, the water of the useless paint of band flows to circulating water pool and recycles, the air being removed coating cloud by exhaust blower through exhaust duct discharged to outside factory building.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Embodiment 1
A kind of cascade water-spinning spray chamber, as shown in Figure 1, primary filter cotton 3 is set between dynamic pressure case 1 and plenum chamber 2, arrange sub-high efficiency filter floor 4 between plenum chamber 2 and spraying operation room 11, spraying operation room 11 is provided with spraying workpiece 5, and the sidewall of spraying operation room 11 is provided with the first water curtain 6, spraying workpiece 5 bottom is provided with tank 7, the bottom periphery of tank 7 is provided with the second water curtain 8, and the bottom of tank 7 is provided with water spigot 12, and water spigot 12 is connected with exhaust blower 9 by air draft passage 10.
The material of the first water curtain 6 and the second water curtain 8 is stainless steel.Primary filter cotton is synthetic fibers filter cotton, non-woven fabrics filter cotton.
Described sub-high efficiency filter layer is filled with synthetic fibers filter cotton.
The stage casing of described air draft passage 10 is provided with water fender 13.
Flocculant is added with in the water of tank 7.Flocculant is the material composition of following portions by weight: polyacrylamide 30-40 part, aluminum sodium sulfate 25-40 part, sodium carbonate 10-30 part, sodium metaaluminate 1-5 part and plant polyphenol 1-5 part.Plant polyphenol is vine polyphenol, apple polyphenol or Tea Polyphenols.
The draft type of this paint spray booth is top side face air-supply, bottom drawing.The process of its coating cloud be utilize the curtain shape water layer of side flow to collect and take away coating cloud more logical bottom water spigot make water fogging after rinse air, purification coating cloud.Be provided with the effect that primarily efficient filter wool plays current-sharing air between dynamic pressure room and plenum chamber, between plenum chamber and paint spraying room, be provided with sub-high efficiency filter floor, ensure the cleanliness factor entering indoor air, make the air-flow sent here in operation room simultaneously evenly.
One tank is arranged at the bottom of water-spinning spray chamber, and water is evacuated to tank by pump, water along trough rim overflow, and along base plate flow into equably middle part water spigot in.Under the action of the forces of the wind, mix, by soluble in water for the coating cloud particle in gas with the gas of coating cloud and water.Be added with flocculating agent in water, make paint drop onto with regard to phase inter coagulation in water, the water of the useless paint of band flows to circulating water pool and recycles, the air being removed coating cloud by exhaust blower through exhaust duct discharged to outside factory building.
