Description

Technical Field

[0001] This application belongs to the technical field of filter cartridges, and specifically relates to a dust removal filter cartridge that is easy to replace. Background Art

[0002] Dust collection and filtration is a means for various industries to often involve purposes such as recycling raw materials and purifying air. Conventional dust collection filters usually include upper and lower end caps, and filter materials are arranged between the upper end cap and the lower end cap. For example, in the pulse dust removal used in down-the-hole drills, the air with dust enters from the outside of the filter material, and the filtered air is discharged from the middle of the filter. After the filter material is used for a period of time, a large amount of dust will be adsorbed on the surface of the filter material. When the dust accumulates to a certain extent, it will cause the air flow to be unable to move, resulting in a blockage situation;

[0003] After retrieving the patent document of CN 219072434 U, a dust removal filter cartridge with multi-stage filtration is disclosed, which includes a filter medium, an upper end cap installed at the top of the filter medium, and a lower end cap installed at the bottom of the filter medium. An annular embedding groove is opened in a week on the inner wall of the upper end cap. A connecting cover is connected to the lower end cap by internal threads. A first filter screen is fixedly connected at the inner opening of the connecting cover. A second filter screen is sleeved outside the first filter screen. The first filter screen and the second filter screen are connected by a connecting rod. An embedding ring is fixedly connected to the top of the second filter screen, and the embedding ring is inserted into the embedding groove. This utility model can completely filter the dust in the gas through the structure composed of the filter medium, the first filter screen and the second filter screen, making the dust removal effect of the dust removal filter cartridge better.

[0004] However, through the exploration of the inventor of this application, it is found that this technical solution still has at least the following defects:

[0005] When the filter cartridge is filtering, a large amount of dust will adhere to its surface. After long-term use, the filter cartridge needs to be disassembled and cleaned or replaced. In this structure, the filter screen cannot be replaced separately. When disassembling, it needs to be completely removed, which is time-consuming and also a waste of materials. Content of the Utility Model

[0006] The purpose of this application is to provide a dust removal filter cartridge that is easy to replace in order to solve the above-mentioned problems.

[0007] The technical solution adopted in this application is as follows: A dust removal filter cartridge that is easy to replace includes a retention mechanism. A filter cartridge mechanism is arranged inside the retention mechanism, and a lower detachable mechanism is arranged at the lower end of the filter cartridge mechanism; the retention mechanism includes an upper fixing ring. A connecting reinforcement plate is fixedly connected to the rear end inside the upper fixing ring. A plurality of first threaded nails are arranged at the front end of the connecting reinforcement plate. A lower fixing ring is fixedly connected to the lower side of the rear end of the first threaded nail. The first threaded nail and the lower fixing ring are threadedly fixed through the intersection with the upper fixing ring.

[0008] By adopting the above technical solution, the retention mechanism is fixed. After fixation, the filter cartridge clamped by the upper support plate and the limiting ring, as well as the threaded ring, are clamped by the upper fixing ring and the reinforcing threaded nails. After clamping, the filter cartridge mechanism is retained through the connecting threaded holes and the reinforcing threaded nails. After retention, the dust outlet hopper is connected through the threaded connection between the connecting ring and the threaded ring. By driving the connecting ring to rotate through the grasping handle, the dust outlet hopper can be removed separately, so that the filter cartridge mechanism can be disassembled and installed separately.

[0009] In a preferred embodiment, the filter cartridge mechanism includes an upper support plate. A filter cartridge is fixedly connected to the lower end of the upper support plate. A limiting ring is arranged on the upper side of the outer end of the filter cartridge. The upper support plate and the limiting ring are snap-connected to the upper fixing ring.

[0010] By adopting the above technical solution, after connecting the limiting ring and the filter cartridge first, then the filter cartridge inside the upper support plate and the limiting ring is snap-connected to the upper fixing ring to connect the filter cartridge.

[0011] In a preferred embodiment, a threaded ring is fixedly connected to the lower end of the filter cartridge. The threaded ring is snap-connected to the lower fixing ring. A reinforcing threaded nail is arranged at the front end of the lower fixing ring. A connecting threaded hole adapted to the reinforcing threaded nail is opened at the front end of the threaded ring.

[0012] By adopting the above technical solution, after the threaded ring is snapped into the inside of the lower fixing ring, the threaded ring is rotated and then the threaded ring and the filter cartridge above the threaded ring are reinforced through the reinforcing threaded nail and the connecting threaded hole.

[0013] In a preferred embodiment, the lower detachable mechanism includes a connecting ring. A dust outlet hopper is fixedly connected to the lower end of the connecting ring. A plurality of handles are fixedly connected to the outer end of the connecting ring.

[0014] By adopting the above technical solution, the protrusion of the handle facilitates twisting the connecting ring to drive the connecting ring to screw in and out.

[0015] In a preferred embodiment, the connecting ring is threadedly connected to the outer end of the threaded ring, and the filter cartridge is snap-connected to the limiting ring.

[0016] By adopting the above technical solution, the threaded connection between the connecting ring and the threaded ring facilitates the disassembly of the connecting ring.

[0017] In a preferred embodiment, a support fixing ring is arranged at the hinge joint between the limiting ring and the filter cartridge. A clamping interface is arranged on the support fixing ring. A clamping block is arranged on the inner ring of the limiting ring. The upper end of the clamping interface is in an open shape, and the lower end of the clamping block is an open strip.

[0018] By adopting the above technical solution, the clamping block and the clamping interface can fix and disassemble the filter cartridge and the limiting ring.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are as follows:

[0020] In this application, the retention mechanism is fixed. After fixing, the filter cartridge and the threaded ring clamped by the upper support plate and the limiting ring are clamped by the upper fixing ring and the reinforcing screw. After clamping, the filter cartridge mechanism is retained through the connecting threaded hole and the reinforcing screw. After retention, the dust outlet hopper is connected through the threaded connection between the connecting ring and the threaded ring. At the same time, when it is necessary to disassemble and replace the filter cartridge, by grasping the handle and driving the connecting ring to rotate, the dust outlet hopper can be taken off separately, so that the filter cartridge mechanism can be disassembled and installed separately. Through the cooperation of the above structures, it is convenient to replace the filter screen separately. BRIEF DESCRIPTION OF THE DRAWINGS
