Waste gas filtering device for automobile coating workshop

Abstract

The invention discloses a waste gas filtering device for an automobile coating workshop, relates to the technical field of waste gas filtering, and aims to solve the problems that as a filter element is directly connected with a ventilation opening in an existing coating workshop, the service life of the filter element is influenced due to the fact that the filter element is possibly blocked by impurities, and time is wasted and the production efficiency is influenced when the filter element is replaced. The waste gas filtering device comprises a filter box, wherein the front portion of the filter box is fixedly connected with a group of air suction cylinders, a group of ash filtering cylinders are connected in the air suction cylinder in an engaged manner, a group of driven impellers are rotationally connected into the air suction cylinder, the front portion of the air suction cylinder is rotationally connected with a group of connecting rings, and four groups of waste gas filter elements are connected into the filter box in a sliding manner. According to the invention, the waste gas filter element is fixed through the filter element lock pin to realize quick replacement, so that the working efficiency is improved; and the driven impeller drives the rear ash removal brush to rotate to realize ash removal, so that the problems of blockage and the like caused by the fact that impurities such as dust and waste gas pass through the waste gas filter element together are prevented, and the service life of the waste gas filter element is prolonged.

Description

technical field [0001] The invention relates to the technical field of exhaust gas filtration, in particular to an exhaust gas filtering device for an automobile painting workshop. Background technique [0002] The coating production line is a full-line workpiece conveying system that uses a combination of aerial suspension and ground skids for mechanized conveying. For the automobile painting workshop, in order to improve the production efficiency of automobile painting, because the materials used in the painting are volatile, most of the painting waste gas also includes ethyl acetate, butanone, isopropanol, ethers, etc. Therefore, the coating production line needs to be kept sealed, and the waste is collected through the ventilation holes of the painting workshop, and the purified gas can only be discharged after the exhaust gas is purified. [0003] For example, the Chinese invention patent with application number: CN201910690792.2, which relates to the field of air puri...

Problems solved by technology

[0005] The purpose of the present invention is to provide an exhaust gas filter device for automobile painting workshops to solve the problem that the existing painting workshops usually directly connect the filter element with the air vent to collect the generated exhaust gas, and filter some components of the exhaust gas before Harmful substances are neutralized through chemical reactions, and there are many other impurities in the painting workshop. If they pass directly through the filter element, the impurities may block the filter element and affect the service life of the filter element; at the same time, the filter element is generally a one-piece structure, and it is time-consuming to replace it. , resulting in more troublesome replacement of the filter element, which affects work efficiency and production efficiency; at the same time, when the production speed is low, the exhaust gas flow rate is slow, and the untreated exhaust gas may appear backflow phenomenon, which affects the exhaust gas treatment work.
