Embodiment 1

[0015] Such as figure 1 As shown, it includes a cylindrical filter cylinder 1 and a partition 2 in the box.

[0016] Such as image 3 As shown, the filter cylinder 1 is composed of an inner metal mesh 3 , an outer metal mesh 4 and a filter material 5 filled between the inner metal mesh 3 and the outer metal 4 . Such as figure 2 , image 3 As shown, the upper end of the filter cylinder 1 is equipped with an annular upper fixed cover 6, and the lower end of the filter cylinder 1 is equipped with a circular lower fixed cover 7 that closes the lower end surface of the cylinder.

[0017] Such as Figure 4 , Figure 5 As shown, the annular surface of the upper fixed cover 6 contains an annular top plane 8 and an inner annular facade 9 bent along the inner and outer edges of the annular top plane 8, an outer annular elevation 10. A sealing ring 11 is fixedly connected to the circular top plane 8 . Three hook plates 12 protruding in parallel above the circular top plane 8 are ...

Abstract

The invention relates to a hook-typed air filter cartridge device which is characterized by comprising a filter cartridge and a box inner diaphragm, wherein, the upper end of the filter cartridge is close to a vent of the box inner diaphragm; an internal annular vertical face is fixedly connected with at least two hook-plates which are separated from each other and parallelly protrude above an annular top surface; the periphery of the vent of the box inner diaphragm is provided with gaps which are matched with the hook-plates; when the hook-plates are pushed into the gaps, the bottom line of the hook-plates are parallel to the upper surface of the box inner diaphragm; and a sealing ring is attached to the lower surface of the box inner diaphragm. The hook-typed air filter cartridge device has the advantages that: (1) installing and dismantling of the air filter cartridge are very simple and convenient; (2) the interference to the air circulation after purification is prevented; and (3) the direct short-distance mutual compassions between an upper fixing cover of the filter cartridge and the box inner diaphragm is realized and the sealing effect of the sealing ring between the upper fixing cover and the box inner diaphragm is enhanced.

Description

technical field [0001] The invention relates to a hook-type air filter cylinder device, which belongs to the technical field of air filter devices. Background technique [0002] The air filter cartridge is an important part of various air filter equipment, and it is generally installed in the casing of the air filter equipment. The common installation structure of the existing air filter cartridge in the box is that a partition is set in the box to divide the box into two closed chambers (inlet chamber and air outlet chamber), and the air filter cartridge is located in the air inlet chamber. A long screw is installed in the center of the air filter cartridge, one end of the long screw passes through the bottom cover of the air filter cartridge, and the air filter cartridge is fastened to the partition by tightening the nuts at both ends of the long screw rod; the top cover of the air filter cartridge A sealing ring is arranged to seal the space between the top cover and the...
