Water curtain spray booth

Abstract

The invention discloses a water curtain type paint spraying room. The water curtain type paint spraying room is characterized that the paint spraying room is divided into a spraying chamber and a gas-liquid recycling chamber through a vertical partition plate, three overflow grooves are formed on the top of the paint spraying room, inclined water curtain plates are arranged at a overflow opening of each overflow groove, three water curtain plates are parallel to one another, the bottom of the paint spraying room is provided with a water containing tank, a gas and liquid circulating channel isreserved between the lower end of the vertical partition plate and a bottom plate of the water containing tank, a spraying workbench and a paint spraying gun are arranged in the spraying chamber, a gas-water separator and an exhaust fan are arranged in the gas-liquid recycling chamber, the spraying chamber is provided with an air inlet, and air flow sent by the air inlet sequentially passes through three water curtains and then passes through the gas and liquid circulating channel at the lower end of the vertical partition plate and sent into the gas-liquid recycling chamber, and then is discharged outwards through the exhaust fan after being separated by the gas-water separator. The water curtain type paint spraying room has the advantages that paint mist diffused in air can be fully fused with water, and the paint mist purification efficiency is improved.

Description

technical field [0001] The invention relates to spraying technology, in particular to a water curtain type spray booth. Background technique [0002] In the field of industrial painting (such as the painting of automobile bodies, auto parts, household appliances, etc.), painting operations must be carried out in a clean environment equipped with air-conditioning and air supply devices, usually with a dedicated spray booth. In order to reduce the dispersion of paint mist, wet spray booths with water curtain devices have been well applied. [0003] In the existing water curtain spraying device, a water tank is provided on the top of the cavity, and a water curtain plate is provided in the cavity. The top of the water curtain plate is connected to the water tank. chamber; the top of the paint mist treatment chamber is provided with an exhaust outlet connected with it, and the top of the spray chamber is provided with a constant pressure chamber connected with it. The workpiece...
