AI Technical Summary

Technical Problem

Paint residue and mist generated during the spray painting process result in poor environmental quality inside the spray booth, posing a significant health hazard to workers. Furthermore, paint waste is substantial, and existing adsorbents cannot completely absorb the residue, making paint residue disposal difficult.

Method used

A partition is installed in the spray booth to separate the spraying space from the operator space. A blower and a suction fan guide the paint mist to the collection box, and the paint residue falls directly into the collection box.

Description

Technical Field

[0001] This utility model relates to the field of paint booth technology, specifically to a paint booth with air filtration. Background Technology

[0002] The surfaces of some equipment casings or components require painting to protect them. Spray painting booths are crucial for painting and drying. During the painting process, especially when done manually, paint residue and large amounts of paint mist are inevitably generated, resulting in poor environmental quality within the spray painting booth and posing health risks to workers. Paint mist and residue falling to the ground pollute the surface, and discharge through water tanks generates significant wastewater, wasting resources.

[0003] In existing technologies, absorbent material is placed on the inner wall of the spray booth to filter the paint mist and prevent it from contaminating the inner wall of the spray booth. However, once the absorbent material absorbs the paint mist, the paint cannot be reused, which will result in waste of paint. In addition, the absorbent material will not completely absorb the paint mist and paint residue, and some paint residue will still fall to the ground. The treatment of paint residue on the ground is still troublesome, and the working environment for operators is still very poor. Utility Model Content
