Problems solved by technology

[0003] The traditional paint mist filter module has two structures, one is a labyrinth baffle structure, which separates the paint mist through the action of centrifugal force, the advantage is that it is not easy to block, the disadvantage is that the wind resistance is large, and the separation efficiency for small particle size particles is low
One is a porous material structure, which works through collision and adsorption. The advantage is small wind resistance and high separation efficiency for small particle size particles. The disadvantage is that it is easy to clog after a period of use.

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] Such as Figure 1-11 As shown, the filter module used to separate the overspray paint mist in the airflow of the present invention includes: a filter structure 10, a housing 20; the filter structure 10 is divided into two areas, according to the order in which the air flow 30 passes through, first through the baffle area 11 , and then pass through the multi-layer filter area 12; the baffle area 11 has a good filtering effect on the large-size paint mist 40 particles in the airflow 30, and has a poor filtering effect on the small-size paint mist 40 particles with a diameter of about 10 μm, and the baffle area 11 The unique structure is not easy to block, has a large paint capac...

Abstract

The invention discloses a filtering module for separating over-spray paint mist in airflow. The filtering module comprises a filtering structure mounted in a shell, an air inlet is formed in one end of the shell, an air outlet formed in opposite other end, and the filtering structure sequentially forms a baffling area and a multilayer filtering area from the air inlet to the air outlet; the baffling area comprises at least two layers and is formed by arranging a plurality of baffling plates with U-shaped opening structures in parallel, the baffle plates on the same layer are spaced by a certain distance to form a baffling air channel, the positions of every two adjacent layers of baffle plates are staggered, the direction of each U-shaped opening is opposite to the advancing direction of air flow, and the space in each U-shaped opening is a paint storage chamber and is used for changing the advancing direction of the entering air flow to make paint mist particles directly collide withthe baffle plates and be captured in the paint storage chamber; and the multilayer filtering area is formed by folding a plurality of layers of sheet-shaped or strip-shaped filtering materials which are attached together in an S-shaped mode, and the multilayer filtering area comprises a coarse filtering layer, a fine filtering layer and a supporting layer according to the airflow passing sequenceand is used for enabling airflow flowing out of the baffling area to flow through, be filtered and then be discharged. The filtering module is good in filtering efficiency.

Description

technical field [0001] The invention relates to the technical field of filter modules, in particular to a filter module used for separating overspray paint mist in air flow. Background technique [0002] During the spraying process, if the paint is atomized and sprayed with a spray gun or an atomizer, a part of the atomized paint mist particles will adhere to the target workpiece, and the remaining paint mist particles will float into the nearby air and The airflow in the spray booth is directed to the treatment device. One of the treatment devices is a dry paint mist treatment system with replaceable filter modules. The airflow containing paint mist is guided and passed through the filter modules. The filter modules separate and absorb most of the paint mist particles. When the filter module is saturated, the saturated module can be taken out and replaced with a new one. [0003] The traditional paint mist filter module has two structures, one is a labyrinth baffle struct...
