Large dry-type paint spray booth with two-vertical-side-face air suction function

Abstract

The invention discloses a large dry-type paint spray booth with the two-vertical-side-face air suction function. The large dry-type paint spray booth comprises a paint spray booth insulation chamber body, a pressure equalizing air feeding chamber, a left air suction vertical face, a right air suction vertical face, a left side paint mist filter screen, a right side paint mist filter screen, a left pneumatic reversing valve and a right pneumatic reversing valve. The left air suction vertical face and the right air suction vertical face are arranged on the left side and the right side of the inner wall of the paint spray booth insulation chamber body respectively. The left side paint mist filter screen and the right side paint mist filter screen are arranged on the outer surfaces of the left air suction vertical face and the right air suction vertical face respectively. The left pneumatic reversing valve and the right pneumatic reversing valve are arranged at the tops of the left air suction vertical face and the right air suction vertical face respectively. In this way, the air suction vertical faces are arranged on both sides of the paint spray booth insulation chamber body, the air suction vertical faces are manually controlled to be switched through the pneumatic reversing valves, an operator can stand in the opposite position of the suck-out face of paint mist all the time, the use performance of the large dry-type paint spray booth is achieved, and the safety and the physical health of the operator are guaranteed.

Description

technical field [0001] The invention relates to the field of painting and spraying equipment for large-scale components such as steel structures and machine tools, and in particular to a large-scale dry paint spraying room with ventilation on two side facades. Background technique [0002] At present, for the same type of painting equipment, the suction of oversprayed paint mist is almost always exhausted from the trench or unilaterally ventilated and filtered. Trench ventilation design requires a deep trench. Excavating the trench in the completed workshop will cost a long time and take a long time, and the second is high cost. Most of them will use one-side facade ventilation to suck out the paint mist that has been sprayed. [0003] The workpieces sprayed in large dry spray booths are relatively large. If a spray booth with one side facade is used, people will always stand between the workpiece and the draft facade when spraying one side, which is unavoidable. The operat...

Problems solved by technology

Trench ventilation design requires a deep trench. Excavating the trench in the completed workshop will cost a long time and the construction time will be long. Second, the cost will be high. Most of them will use one-side vertical ventilation to suck out the paint mist that has been sprayed.

[0003] The workpieces sprayed in large dry spray booths are relatively large. If a spray booth with one side facade is used, people will always stand between the workpiece and the draft facade when spraying one side, which is unavoidable. The operator will be sprayed by paint mist and inhale harmful solvent-containing waste gas in severe cases
