Description

A kind of bag-type dusting paint spray booth

Technical field

The utility model relates to a kind of paint mist purifying means, specifically is a kind of bag-type dusting paint spray booth.

Background technology

Existing paint spray booth is divided into wet type spray chamber and dry spray booth by the processing mode to coating cloud, wet type spray chamber is that moisture film or water smoke are set in clean-up stage, by making the waste gas that contains coating cloud by moisture film or water smoke and coating cloud is washed and will be got off, the problem that this paint spray booth exists is that purification efficiency is not high, and can cause secondary water to pollute.Dry spray booth is provided with filter courses such as glass fibre or filter paper in clean-up stage, coating cloud in the waste gas is held back also and air separation through filter course by making the waste gas that contains coating cloud, the shortcoming of this paint spray booth is that filtering material can only use once, can not reuse, because the wet paint mist sticks on the filter course and can't separate, can only treat saturated then together throwing away, therefore simultaneously with filter course, can produce a large amount of solid waste, and because the frequent filtering layer of changing makes also workman's workload increase.。

Summary of the invention

The purpose of this utility model is to provide a kind of purification efficiency height, do not produce secondary water pollutes and solid waste, and power saving, saving of labor's bag-type dusting paint spray booth.

The purpose of this utility model reaches by following technical measures: this bag-type dusting paint spray booth comprises housing and wind collection scoop, comprise the section of spraying paint and clean-up stage in the housing, wind collection scoop is fixed on an end of housing clean-up stage, between housing section of spraying paint and clean-up stage, also be provided with the dryer section that can make coating cloud become the lacquer ash, be fixed with several rows of vertical skeleton in the housing clean-up stage, be set with filter bag on the skeleton, the adjacent dryer section one end sealing of skeleton, adjacent wind collection scoop one end does not seal; Side at housing also is equipped with gas bag in addition, gas bag links to each other with air compressor by compressed air hose, also be connected with appendix on the gas bag simultaneously, the radical of appendix is identical with row's number of skeleton, before pulse valve being installed on the every appendix and stretching to a sparerib shelf, be processed with on the appendix over against the skeleton pore of blind end port not.

In the above-mentioned solution, skeleton also can not installed venturi winding-up pipe in the blind end port.

The course of work of the present utility model is: workpiece sprays paint in the section of spraying paint, coating cloud enters dryer section by the section of spraying paint, after the drying section, the wet paint mist of viscosity becomes noncohesive dried lacquer ash, under the effect of air exhauster, the waste gas that contains the dried lacquer ash passes through filter bag, its dried lacquer is adsorbed on the filter bag, cleaned air passes is then extracted out from wind collection scoop through the skeleton openend, after work a period of time, pulse valve is opened under the effect of control panel, compressed air enters appendix from gas bag, again the aperture on appendix from skeleton not the blind end port blow into, the dried lacquer ash that is adsorbed on the filter bag is blown off in housing, than the time filter bag totally can continue again as before to use, and the workman only needs the lacquer ash in a period of time cleaning housing to get final product.

The utility model is compared with dry spray booth with wet type spray chamber has following effect respectively:

(1) compare with wet type spray chamber and have: a, purification efficiency height, purification efficiency are higher than wet method efficient greater than 99.99%; B, no secondary water pollute and produce; C, need not use water pump, economize on electricity.

(2) compare with dry spray booth and have; A, filtering layer are reusable, and be therefore cost-saved, and also can not produce a large amount of solid waste; B, can remove the work of frequent replacing filtering layer from, thereby reduce working strength of workers, increase work efficiency.

Below in conjunction with drawings and Examples the utility model is described in further detail:
