Description

A water curtain spray booth

technical field

The invention relates to the technical field of environmental protection equipment, in particular to a water curtain type paint spraying room.

Background technique

Water curtain spray booths are widely used in heavy industry machinery, automobile industry, aerospace industry, machine tool manufacturers, motor manufacturing, water pump equipment factories, furniture and other industries to paint the whole machine or parts.

The water curtain spray booth uses the circulating water in the spray booth to bring out the residual paint gas in the air, which can avoid the high concentration of paint gas in the spray booth, which will affect the product quality and endanger the health of the sprayer. However, because the circulating water dissolves the paint After a long period of use, the effect of dissolving paint will be reduced. At this time, the paint gas will easily leak out, resulting in unstable pumping effect. Therefore, it is necessary to stop work and change the water, which not only affects the production of the factory, but also increases the treatment of waste water. load and cost. Therefore, there is an urgent need for those skilled in the art to develop a water curtain spray booth.

In order to achieve the above purpose of the invention, the technical solution provided by the present invention is as follows: a water curtain spray booth, which includes an operation workshop, a water curtain spray booth, an activated carbon waste gas purifier, an exhaust static pressure box, an explosion-proof exhaust fan, and an air volume control valve. and exhaust pipes, the water curtain painting room is set in the operation workshop, and the water curtain painting room is provided with a water curtain board, a water tank and a water retaining plate, the water curtain board is used to generate a water curtain, and the water tank A paint mist coagulant is added inside, the water curtain plate is arranged above the water tank, a water blocking plate is arranged above the water curtain plate, an activated carbon waste gas purifier is arranged on the upper end of the water curtain paint spraying room, and the activated carbon waste gas is arranged The purifier is connected with the exhaust static pressure box, at least two explosion-proof lighting lamps are arranged at the top of the operation workshop, and the exhaust static pressure box is connected with the explosion-proof exhaust fan through an external exhaust connection pipe. One end of the explosion-proof exhaust fan is provided with an exhaust duct, and an air volume regulating valve is arranged at the connection between the explosion-proof exhaust fan and the exhaust duct.

Preferably, the angle formed between the water blocking plate and the horizontal plane is 30-45 degrees.

Preferably, the model of the paint mist coagulant is YQ-602A and/or YQ-602B.

Based on the above technical solutions, the present invention has the following technical advantages compared with the prior art:

The invention adopts a water curtain type spray booth, which has reasonable structure design and good environmental protection effect. The paint mist coagulant can be used to remove the dissolved paint in the water tank. Cleaning is carried out so that the water quality is stable and the waste water treatment load can be greatly reduced.

Detailed ways

The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, a water curtain spray booth includes an operation workshop 1, a water curtain spray booth 2, an activated carbon waste gas purifier 3, an exhaust static pressure box 4, an explosion-proof exhaust fan 5, an air volume control valve 6 and a discharge The air duct 7, the water curtain spray booth 2 is set in the operation workshop 1, and the water curtain spray booth 2 is provided with a water curtain board 2-1, a water tank 2-2 and a water blocking plate 2-3. The curtain plate 2-1 is used to generate a water curtain, the water tank 2-2 is filled with paint mist coagulant, the water curtain plate 2-1 is arranged above the water tank 2-2, and the water curtain plate 2 -1 A water baffle 2-3 is arranged above, an activated carbon waste gas purifier 3 is arranged on the upper end of the water curtain spray booth 2, and the activated carbon waste gas purifier 3 is connected with the exhaust static pressure box 4, and the operation workshop 1 The top is provided with at least two explosion-proof lighting lamps 8, the exhaust static pressure box 4 is connected with the explosion-proof exhaust fan 5 through an external exhaust connection pipe 9, and one end of the explosion-proof exhaust fan 5 is provided with an exhaust duct 7. , an air volume regulating valve 6 is provided at the connection between the explosion-proof exhaust fan 5 and the exhaust duct 7 .

The angle formed by the water blocking plate 2-3 and the horizontal plane is 30-45 degrees. The model of the paint mist coagulant is YQ-602A and/or YQ-602B.

Under the negative pressure of the explosion-proof exhaust fan 5, the airflow containing paint mist first hits the water curtain formed by the water curtain plate 2-1, and the paint mist is washed into the water tank 2-2. Under the action of the water curtain plate 2-1, a high-speed descending water curtain barrier is formed, and part of the paint mist is washed into the water tank 2-2 when it passes through the water curtain barrier, and then the air enters the water curtain plate 2-1. In the rear air-water channel 10, the air rises under the negative pressure of the explosion-proof exhaust fan 5, passes through the water baffles 2-3 and the activated carbon waste gas purifier 3 and is discharged to the outside.
