Problems solved by technology

[0002] Today's bag filter is a dry dust filter, which is suitable for collecting fine, dry, non-fibrous dust; because the current bag will accumulate dust after a period of time, and the bag will be blocked due to excessive dust. The bag needs to be disassembled and cleaned in time. The whole process is cumbersome and increases the labor intensity of the staff. Moreover, the airtightness of the current bag filter is not strong, and sometimes it will cause secondary pollution to the filtered air; there is also the current bag dust collector. The vibration and noise of the device is relatively large, and the bag is easy to be damaged during work

Embodiment 1

[0027] like figure 1 As shown, a bag filter includes a chassis 1, a cover body 2 and a frame 3, the chassis 1 is arranged on the frame 3, the cover body 2 is arranged on the chassis 1, and the middle part of the chassis 1 is provided with a positioning groove, and the positioning groove A filter partition 11 is provided inside, and a through hole is provided on the filter partition 11, and a first metal mesh 12 corresponding to the through hole and whose radius gradually decreases from bottom to top is provided on the filter partition 11. The net 12 is provided with a second metal net 13, and a cloth bag 14 is arranged between the first metal net 12 and the second metal net 13, so that the dust-removing surface of the cloth bag 14 faces the ground, and the dust on the cloth bag 14 is subjected to gravity and accumulates in the cleaning area. On the ash port 18, the amount of dust accumulated on the cloth bag 14 is reduced, and the cloth bag 14 is set between the first metal me...

Embodiment 2

[0038] like figure 2 As shown, a bag dust collector, compared with Embodiment 1, differs in that the lower part of the electric valve 19 is connected with a dust basket 110, and the frame 3 is provided with an exhaust device corresponding to the dust basket 110 31. There is a manual sealing valve 111 on the intake pipe 17. When cleaning the dust inside the bag filter, the manual sealing valve 111 seals the intake pipe 17, opens the electric valve 19 and the exhaust device 31, and collects the dust in the dust basket 110 Among them, while reducing the labor intensity of the workers, the part of the dust accumulated in the cloth bag 14 is also cleaned, and the rest are the same as in Embodiment 1, and are not particularly limited here, and all belong to the protection scope of the present invention. Its production process is also the same as in Example 1, and will not be repeated here.

Abstract

The invention relates to an air purifying device, in particular to a bag type dust collector. The bag type dust collector comprises a machine box, a cover and a rack. The machine box is arranged on the rack, the cover is arranged on the machine box, a positioning groove is formed in the middle of the machine box, and a filtering partition plate is arranged in the positioning plate. The filtering partition plate is provided with a through hole and a first metal net corresponding to the through hole, and the radius of the first metal net gradually becomes smaller from bottom to top. A second metal net is arranged on the first metal net, and a bag is arranged between the first metal net and the second metal net. The cover is provided with a first guide plate and an exhaust pipe, wherein the first guide plate corresponds to the bag. The machine box is provided with a sealing door corresponding to the filtering partition plate and the second metal net. An air inlet pipe is arranged on the side wall, below the filtering partition plate, of the machine box. The bottom of the machine box is conical. A dust removing opening is formed in the middle of a bottom plate of the machine box and provided with a power-driven valve, and the side wall of the machine box is a hollow plate. The sealing performance is high, the amount of accumulated dust on the bag is reduced, the bag is prevented from being damaged during working, and noise is lowered.

Description

technical field [0001] The invention relates to air purification equipment, in particular to a bag filter. Background technique [0002] Today's bag filter is a dry dust filter, which is suitable for collecting fine, dry, non-fibrous dust; because the current bag will accumulate dust after a period of time, and the bag will be blocked due to excessive dust. The bag needs to be disassembled and cleaned in time. The whole process is cumbersome and increases the labor intensity of the staff. Moreover, the airtightness of the current bag filter is not strong, and sometimes it will cause secondary pollution to the filtered air; there is also the current bag dust collector. The vibration and noise of the device is relatively large, and the bag is easily damaged during work. Contents of the invention [0003] In order to solve the above technical problems, we propose a bag filter, the purpose of which is to enhance the sealing performance, reduce the amount of dust accumulated o...
