Abstract

A recovering filter for dust or powder spray device comprises a filtering chamber (1), filter elements (2) and an intake chamber (3), wherein, the filter elements (2) are arranged inside the filtering chamber (1); the top of the filtering chamber (1) is provided with a plurality of inlet openings (4), the directions of which are the same as the axial directions of the filter elements (2); the upside of the filtering chamber (1) is provided with an intake chamber (3) which is communicated with the filtering chamber (1) through the inlet openings (4); the intake chamber (3) causes the airflow to blow off part of the dust or powder adsorbed on the exterior of the filter elements (2) from top to bottom, which is beneficial for the falling of the dust or powder when the filter elements work; the running direction of the airflow is downwards, the dust or powder falling to the inside of the filtering elements is less, thereby prolonging the service life of the filter elements (2); the intake chamber (3) is arranged on the top and is provided with a plurality of inlet openings, so that the airflow around the filter elements is blew downwards to the inside of the filtering chamber with better filtering effect; the arrangement of air dividing baffles of air channels makes the wind rate entering each air channel controllable, so that the wind rate of each filter element and the work load of filtering are the same.

Description

The recovery filter of dust or powder spray coating device

1, technical field:

The utility model relates to the recovery filter of dust or powder spray coating device.

2, background technology:

At present, it is that dust contained in the air or powder filter are come out that the recovery filter of dust or powder spray coating device mainly acts on, play the effect that economizes in raw materials and purify air, in existing dust or powder spray coating device, the air intake that reclaims filter element is the periphery that faces filter core, it is the periphery of vertical filter core, as Fig. 1, Fig. 2 institute formula, its advantage is simple in structure, shortcoming is that dust or the powder in the air-flow flings filter core, causes that than being easier to the filtration object is that dust or powder are poured filter element filtering material internal layer, and is not easy to be cleared, thereby stop up the filter core flow area, reduce the service life of filter core.In addition, for filter core, vertically its surperficial air-flow directly blows to and be unfavorable for that filter core blows out and make it to fall filtering object when reverse impulse or blowback cleaning, because the exhausting direction of filter core itself is the periphery of vertical filter core.In addition, the air quantity that each filter core flow through according to apart from the distance of air inlet, towards the area of air intake air-flow, and the air inlet position different and different, make separately workload and service life different or differ far away, cumbersome during replacing.

3, summary of the invention:

The purpose of this utility model provides the recovery filter of dust or powder spray coating device, it is by changing the position and the direction of air inlet, thereby the axis of pitch that makes airflow direction and filter core in the same way, and airflow direction is from top to bottom, blow dust or powder that a part is adsorbed on the filter core outer surface off, its operating efficiency in the service life of prolongation filter core, is improved in the whereabouts of dust or powder when being beneficial to the filter core cleaning.

The utility model is achieved by the following technical solution: it comprises filter chamber, filter core and inlet air plenum, filter core is installed in the inside, filter chamber, the top of filter chamber is provided with a plurality of air inlets, the direction of air inlet and the axis direction of filter core are in the same way, be provided with inlet air plenum on the filter chamber, inlet air plenum is communicated with the filter chamber by air inlet.

Above-mentioned described air inlet one side is provided with the branch windshield plate of holding up.

The utility model compared with prior art has following advantage: 1) change the position and the direction of air inlet, make air-flow from top to bottom will blow dust or the powder that a part is adsorbed on the filter core outer surface off, the whereabouts of dust or powder when being beneficial to the filter core cleaning; Simultaneously because the traffic direction of air-flow is downward, the exhausting direction of filter core is a level, air-flow is much smaller can be more identical with filter core exhausting direction than airflow direction the time to the impulsive force of filter core, therefore dust or powder are fallen into the fewer of material for core inside, therefore can prolong the service life of filter core, improve its operating efficiency; 2) inlet air plenum is located at the top and has a plurality of air inlets to make air-flow blow into the filter chamber downwards around filter core, and filter effect is better; Increase the air channel and divide windshield plate, make that the air quantity that enters each air channel is controlled, with reach each filter core intake and workload when filtering roughly the same.

5, the specific embodiment:

As shown in Figure 3, Figure 4, the utility model comprises filter chamber (1), filter core (2) and inlet air plenum (3), filter core (2) is installed in the inside, filter chamber (1), the top of filter chamber (1) is provided with a plurality of air inlets (4), the axis direction of the direction of air inlet (4) and filter core (2) in the same way, be provided with inlet air plenum (3) on filter chamber (1), inlet air plenum (3) is communicated with filter chamber (1) by air inlet (4).Air inlet (4) one sides are provided with the branch windshield plate of holding up (5).

Claims

1, the recovery filter of dust or powder spray coating device, comprise filter chamber (1), filter core (2) and inlet air plenum (3), filter core (2) is installed in the inside, filter chamber (1), the top that it is characterized in that filter chamber (1) is provided with a plurality of air inlets (4), the axis direction of the direction of air inlet (4) and filter core (2) in the same way, be provided with inlet air plenum (3) on filter chamber (1), inlet air plenum (3) is communicated with filter chamber (1) by air inlet (4).
