Description

Technical Field

[0001] The utility model belongs to the technical field of paint spraying rooms, in particular to an air circulation purification device for a paint spraying room. Background Art

[0002] A spray paint room, as the name implies, is a room where the filtered spray paint objects are sprayed and colored. It is also called a paint baking room. A spray paint room is a device that provides a special environment for painting operations. It can meet the requirements of painting operations on temperature, humidity, light intensity, air cleanliness, etc. It can limit and treat the paint mist and organic waste gas generated during the spray painting operation before discharging. It is an environmentally friendly painting equipment.

[0003] At present, most of the paint spraying rooms process the paint mist through the water curtain cabinet. The air containing the paint mist is passed through the water curtain by the curtain exhaust fan to remove the paint mist in the paint spraying room. However, the fan in the water curtain cabinet in the paint spraying room has limited ability to absorb the paint mist, resulting in poor suction force for the paint mist far away from the water curtain cabinet. In order to absorb the paint mist as much as possible, the workpiece needs to be moved to a position close to the water curtain cabinet for painting. When the water curtain cabinet is far away from the entrance of the paint spraying room, the distance that the workpiece needs to be moved will also increase, causing some unnecessary physical effort and affecting the efficiency of painting.

[0004] In summary, the utility model therefore provides an air circulation purification device for a paint spraying room to solve the above problems. Utility Model Content

In the process of the paint mist passing through the treatment box 16, the clean water stored in the treatment box 16 is sucked and pumped into the water delivery main pipe 18 by the water pump 23. After the clean water enters each water delivery branch pipe 19 in the water delivery main pipe 18, it is sprayed out from each spray head 20. The sprayed clean water drives the paint mist in the exhaust gas to settle, thereby realizing the purification of the paint mist in the exhaust gas.
