Background technology
Spraying process often produces substantial amounts of waste gas in the course of processing, and containing substantial amounts of coating particles in waste gas, it not only can
Suck and human body affects the healthy of operator, and can be deposited in processing instrument and auxiliary equipment and cause instrument to damage
Wound.Existing technology there is also by the way of exhaust fan, detach the waste gas produced in spraying process, but due to spraying
Coating viscosities big, cured strength is high, is difficult to clear up when therefore adhering on fan blade, so of the prior art
Blower fan generally requires and carries out cleaning frequently and safeguard blade, and cleaning difficulty is big simultaneously, and directly changes the cost mistake of fan blade
Height, is unfavorable for the popularization of manufacturing enterprise.
Summary of the invention
The technical problem to be solved is: provide the gas recovery method of a kind of spraying coating line, and its waste gas recovery is effective,
Frequency of maintenance and maintenance cost are low.
The technical solution used in the present invention is: provide the gas recovery method of a kind of spraying coating line, and it includes
Step 1, by the nozzle on spraying coating line towards the import position of front chamber, make the waste gas that nozzle spraying workpiece produces
Enter front chamber；
The blower fan that step 2, unlatching connect with rear chamber, for detaching the air in rear chamber, the bottom of described rear chamber sets
There is tank, the horizontally extending bottom to front chamber of tank, it is provided with dividing plate between front chamber and rear chamber, under dividing plate
Leaving gap between horizontal plane in portion and tank, the air in front chamber enters rear chamber through described gap；
Step 3, open water pump, make the sewage in tank be circulated with water treatment system.
Blower fan in described step 2 drives the air-flow in air main to flow towards the one end away from blower fan, and rear chamber is by a connection
Trachea connects with the mid portion of air main, connects trachea and is obliquely installed with air main, and connects trachea away from the one of air main
End is positioned at nearly blower fan side.
Opening the spray nozzle in rear chamber, the air in rear chamber circulates from the bottom up, and the vaporific steam that spray nozzle produces is from upper
Down spray.
Being provided with water screen generator in front chamber, the current that water screen generator produces flow from top to bottom along the inwall of front chamber,
And converge in tank.
Opening the second blower fan, the high pressure draught that the second blower fan produces sprays in front chamber from the import position of front chamber
Penetrate, be used for driving waste gas to enter front chamber.
Tank is arranged over stirring rod, stirs the bottom of rod and contacts with the water surface in tank, when stirring rod and rotating, stirs rod
With the greasy dirt on the water surface in dynamic water tank from front chamber position towards rear chamber's position flowing.
After using above structure, the gas recovery method of the spraying coating line of the present invention compared with prior art has the advantage that head
First, the blade of blower fan being not easy be infected with coating, therefore service life is long, and maintenance cost is low, and secondly, waste gas is at utmost
Be deposited on the water surface, therefore recovering effect is good.

Detailed description of the invention
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
The present invention provides the gas recovery method of a kind of spraying coating line, and it includes
Step 1, by the nozzle on spraying coating line towards import 1.1 position of front chamber 1, make nozzle spraying workpiece produce
Waste gas enter front chamber 1；
The blower fan 3 that step 2, unlatching connect with rear chamber 2, for detaching the air in rear chamber 2, described rear chamber 2
Bottom be provided with tank 4, the horizontally extending bottom to front chamber 1 of tank 4, between front chamber 1 and rear chamber 2
Being provided with dividing plate 5, leave gap 6 between the horizontal plane in the bottom of dividing plate 5 and tank 4, the air in front chamber 1 is through institute
State gap 6 and enter rear chamber 2；
Step 3, open water pump, make the sewage in tank 4 be circulated with water treatment system.
Above-mentioned waste gas refers to the coating particles of the discarded mist formed after nozzle spraying workpiece in spraying process.
Blower fan 3 in described step 2 drives the air-flow in air main 7 to flow towards the one end away from blower fan 3, and rear chamber 2 leads to
Cross a connection trachea 8 to connect with the mid portion of air main 7, connect trachea 8 and be obliquely installed with air main 7, and connect gas
Pipe 8 is positioned at nearly blower fan 3 side away from one end of air main 7.When producing swiftly flowing air-flow in air main 7,
