Description

Technical Field

[0001] This utility model relates to the field of workshop air purification technology, and in particular to an air purification device for a woodworking spray painting workshop. Background Technology

[0002] In the paint spraying workshop, spray guns are mostly used for spraying. A large amount of paint mist is generated during the spraying process. In order to avoid the paint mist from affecting the product, the production line usually absorbs the paint mist by using water curtain suction. However, water curtain suction has certain limitations. Therefore, we use the method of "demisting + activated carbon adsorption" to treat the air in order to improve the purification effect.

[0003] In existing devices, after the gas in the workshop enters the purification device, a lot of dust tends to adhere to the top of the filter screen, requiring staff to clean the filter screen regularly. Furthermore, it is inconvenient to disassemble and replace the activated carbon inside the air purification device. Utility Model Content

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an air purification device for a woodworking spray painting workshop, including an air purification box for the spray painting workshop, a control box fixedly installed on the top of the air purification box for the spray painting workshop, and a woodworking spray painting workshop air purification component arranged above the air purification box for the spray painting workshop and the control box.

The activated carbon storage box is located inside the air purification box of the spray painting workshop. The mounting plate is fixedly installed on the bottom plate of the activated carbon storage box. The fixing bolts are threadedly installed inside the activated carbon storage box and the air purification box of the spray painting workshop. The motor is fixedly installed on one inner wall of the control box. The bidirectional lead screw is fixedly installed at the output end of the motor and is rotatably installed on the front and rear sides of the inner side of the control box.

[0006] As a further improvement to the above solution, a water storage tank is fixedly installed on the top of the control box, multiple air intake pipes are fixedly installed on the left and right sides of the paint spraying workshop air purification box, a water flow guide pipe is fixedly installed between one side of the air intake pipes, a filter screen is fixedly installed on the inner side of the air intake pipes, an air outlet frame is fixedly installed at the bottom of the paint spraying workshop air purification box, a fan is fixedly installed on the inner side of the air outlet frame, and an air intake screen reverse flushing assembly is provided above the control box and the water storage tank.
