Dry paint spraying chamber capable of separating paint from mist

Abstract

The invention discloses a dry paint spraying chamber capable of separating paint from mist. The dry paint spraying chamber comprises a frame mechanism, an air supply and exhaust mechanism and a filtering mechanism, wherein the frame mechanism comprises pressure equalizing chambers, paint spraying chambers and dry filtering chambers; two paint spraying chambers and two dry filtering chambers are arranged; two groups of paint spraying chambers and the dry filtering chambers are symmetrically arranged on the left side and the right side of a proceeding channel respectively; the paint spraying chambers and the dry filtering chambers are respectively located on two sides of the proceeding channel; a movable suspension mechanism is mounted at the top of the proceeding channel and drives a workpiece to enter and exit from a chamber body; two pressure equalizing chambers are respectively mounted above the paint spraying chambers; the air supply and exhaust mechanism comprises an air supply device, an air exhaust device and a ventilation pipe; the filtering mechanism comprises a paper box filtering device and a filtering bag filtering device; the paper box filtering device is close to the proceeding channel and can enter through a replacement door; and paper boxes and filtering bags are replaced by a replacement channel. The dry paint spraying chamber capable of separating paint from mist is simple in structure, small in wind pressure and wind resistance, small in coating loss, low in cost, high in coating efficiency and free of wastewater treatment.

Description

technical field [0001] The invention belongs to the field of spray booths, in particular to a dry paint mist separation spray booth. Background technique [0002] At present, most of the spray booths in the industry use water curtain devices to remove paint mist. The structural feature is that the inner wall of the front of the room is made into a smooth running water board, and the water pump overflows the top of the board to form a waterfall on the board surface. Status of the water curtain. When spraying paint, when the paint mist collides with the water curtain, it will be absorbed by the water and rush to the lower sink to accumulate. Therefore, the wall of the spray booth is not easy to be polluted, and the effect of dealing with paint mist is good. It can be seen that the characteristics of the water curtain spray booth: (1) suitable for coating spraying with low decorative requirements; (2) suitable for continuous and intermittent spraying of small and medium-sized...

AI Technical Summary

Problems solved by technology

[0008] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a dry paint mist separation spray booth, which solves the difficulty of wastewater treatment in the existing water curtain spray booth, and the cost and maintenance of the spray booth for continuous vehicle spraying. The cost is high and the space occupied is large. For small batches and small and medium-sized workpieces, the cost is difficult to cover.
