A paint mist purification device for a paint spraying room

Abstract

The present invention discloses a paint mist purification device for a spray booth, comprising an arc-shaped bracket, a box body and two symmetrically arranged bottom plates, and the present invention relates to the technical field of environmental protection equipment. The paint mist purification device for a spray booth adopts the arrangement of an arc-shaped bracket to install the purification device on the bracket, thereby reducing the occupied area and moving the position of the purification device. The purification device can be controlled to move according to the position of the spray painting, thereby improving the absorption effect of the paint mist and reducing the diffusion of the paint mist in the operation workshop. When the purification device is moving, it is divided into two situations: (1) During the spray painting period: the return air fan at the bottom of the box body blows up the sinking paint mist so that more of it is adsorbed on the surface of the industrial product, thereby reducing the waste of paint; (2) When the spray painting is stopped: at this time, the return air fan stops operating, and the suction fan inside the box body starts working to absorb the paint mist floating in the air into the box body for purification, thereby improving the environmental quality of the operation workshop.

Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to paint mist purification equipment for a paint spraying room. Background Art

[0002] The painting process is a commonly used appearance coating process in the production process of industrial products. Generally, operators are required to perform manual spraying to ensure that the spraying is uniform and there are no dead angles. Nowadays, the paint used for spraying is still mainly solvents. The organic solvents on the surface of the paint film and in the paint mist - benzene, toluene, and xylene - directly evaporate into the workshop air. At the same time, tiny paint mist droplets form dust after the solvent evaporates, which is also dissipated in the workshop air. Triphenyl is a highly toxic solvent and is emitted into the workshop air during operation. After workers inhale it through the respiratory tract, it can cause acute and chronic poisoning, mainly causing damage to the central nervous system and hematopoietic system. Short-term inhalation of high concentrations of benzene vapor can cause aplastic anemia; frequent inhalation of low concentrations of benzene vapor can also cause neurological symptoms such as nausea, vomiting, and confusion, and a few can also cause neurasthenia syndrome.

[0003] The water-based paint mist generated during spraying will adhere to other objects or the human body, quickly forming bright spots, affecting the appearance and causing waste of materials. The existing adsorption purification technology will cause a large amount of paint mist that should be sprayed on the outer wall of the industrial product to be absorbed and purified, resulting in paint waste. In addition, the existing purification equipment generally adopts vertical purification equipment. During the spraying process, due to the different spraying parts, the amount of paint mist that can be absorbed by the purification equipment is also different. When the spraying part is far away from the purification equipment, the purification equipment needs to be moved, which is inconvenient to operate. Summary of the invention

The movement of the box will also drive the internal centrifugal blades to rotate, and the paint in the paint mist is thrown onto the inner wall of the box through the centrifugal effect, causing it to slide down into the interior of the recovery box. After being filtered by the honeycomb zeolite, honeycomb activated carbon and filter cotton inside the exhaust pipe, the gas is discharged into the air, achieving energy saving, environmental protection, low energy consumption and zero emissions.
