Dry type paint mist capturing system and dry type spraying room

Abstract

The invention provides a dry type paint mist capturing system and a dry type spraying room, the dry-type paint mist capturing system comprises a paint mist capturing unit for paint mist separation anda spraying device arranged at a windward opening of the paint mist capturing unit, an upper plate and a lower plate are arranged at the windward opening of the paint mist capturing unit, and a gap isformed between the upper plate and the lower plate. To-be-filtered airflow containing paint particles penetrates through the gap, enters the paint mist capturing unit and is filtered through a filter, and the spraying device comprises a powder spraying opening used for directionally spraying powder, a vibrator used for driving the lower plate to vibrate and a drainage plate used for receiving thepowder; and a plurality of through holes are formed in the lower plate, powder sprayed out of the powder spraying opening falls on the lower plate, and under the vibration effect of the vibrator, thepowder falling on the lower plate penetrates through the through holes and falls to the drainage plate to be collected. Through the system, the phenomena of caking and blocking of the powder and paint can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of spray paint mist filtration, and in particular relates to a dry paint mist capture system which can effectively reduce the agglomeration and clogging of powder and paint; in addition, it also relates to a dry spray booth. Background technique [0002] According to the way of paint mist collection, spray booths can be divided into wet spray booths and dry spray booths; wet spray booths can be divided into Venturi type, water cyclone (power tube type), water curtain type, etc. to capture paint with water. Fog spray booths, dry spray booths can be divided into traditional filter cotton dry spray booths, lime powder dry spray booths and new dry carton spray booths. In the current automotive coating industry, 2K varnishes are widely used due to their good performance. However, due to their high viscosity and easy curing, 2K varnishes pose challenges to the dry spray booth technology that uses lime powder to ca...

AI Technical Summary

Problems solved by technology

[0004] 1. The service life of the filter is low - the paint mist solidifies on the surface of the filter and adheres firmly;

[0005] 2. The amount of lime powder is relatively large;

[0006] 3. The 2K varnish mist solidifies and agglomerates in the filter system of the dry spray booth, which makes it difficult to clean and clean, and the maintenance cost remains high;

[0007] 4. Lime powder is agglomerated, and the failure rate of equipment remains high. Long-term shutdown affects production efficiency
