Industrial dust grading filtration system for paint spraying environment

Abstract

An industrial dust grading filtration system for a paint spraying environment comprises a first frame device (1), a preliminary filtering device (2), a water purification device (3), a first pipe device (4), a second frame device (5), a first filtering device (6), a second filtering device (7), a recycling device (8) and a third filtering device (9). The first frame device (1) comprises a first frame body (11), a first pipe (12), a first fan (15), a first valve (16), a first cross rod (13) and a first support (14). The preliminary filtering device (2) comprises a first baffle (21), a first sponge layer (22) and a first filter screen (23). The water purification device comprises a first transverse plate, a first sponge block, a first spring, a third filter screen and a second sponge block. The industrial dust grading filtration system can thoroughly and effectively filter out and purify dust of sprayed paint, discharged gas is free of pollution and environmentally friendly, and the environment can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an industrial dust classification filter system used in a painting environment. Background technique [0002] At present, in some daily painting operations, a fan is often installed next to it, so that the paint mist or dust generated during the painting process can be directly discharged into the outdoor air. This behavior of random discharge seriously pollutes the environment. And it has a certain impact on people's health, and affects the quality of life of nearby residents. [0003] Chinese patent document CN204684882U discloses a hydrocyclone type paint dust environmental protection treatment equipment, including a purifier housing, a circulating water pool, and a high-pressure axial flow fan. The purifier housing is provided with a dust filter chamber and a filter channel communicating with the circulating water pool. One and filter channel two, the top of...

Problems solved by technology

However, when there is a lot of spray paint dust, part of the dust may still remain after being filtered through channel 1 and channel 2, and it is prone to clogging after being filtered through the bag filter and activated carbon layer, thereby affecting its filtration efficiency and effect. In serious cases, it will even cause damage to it and shorten its service life; at the same time, the water in the circulating pool needs to be recycled. After a period of use, the impurities in the pool will increase, which will affect its purification effect; and the impurities will be deposited in the bag filter. It cannot be effectively removed when it is on the activated carbon layer, making it easy for impurities to accumulate on the filter
