[0026] To facilitate understanding of this invention, a more comprehensive description of the invention will be provided below with reference to specific embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Reference Figure 1 , Figure 2 This embodiment proposes a cartridge dust collector, which includes a housing 1, multiple cartridges 2, multiple end caps 3, and multiple brackets 5.

[0029] The bottom of the housing 1 is provided with support legs 19. The interior of the housing 1 is divided into a filter chamber 11 and a clean chamber 12 by a partition 4. Multiple retaining rings 41 are integrally formed on the side of the partition 4 facing the filter chamber 11, and through holes 42 are opened through the partition 4 within each retaining ring 41. A dust hopper 16 is provided on the housing 1 at the bottom of the filter chamber 11. The housing 1 has an air inlet 17 communicating with the filter chamber 11 and an air outlet 18 communicating with the clean chamber 12. Multiple retaining rings 13 are installed on the outer side wall of the housing 1 opposite to the partition 4. Multiple buckles 15 are circumferentially provided on the outer periphery of each retaining ring 13 and are rotatably mounted on the housing 1. Through holes 14 are opened through the housing 1 within each retaining ring 13 and are coaxial with the multiple through holes 42.

[0030] Multiple filter cartridges 2 are horizontally arranged inside the filter chamber 11, combined with Figure 3 A sealing ring 21 is provided at one end of the filter cartridge 2 near the partition plate 4. Multiple filter cartridges 2 are respectively inserted into multiple retaining rings 41 at their ends near the partition plate 4, with the outer circumferential surface of the filter cartridge 2 fitting against the inner circumferential surface of the retaining ring 41. The outer diameter of the filter cartridge 2 is larger than the diameter of the through hole 41, and a sealing ring 22 is provided at the end of the filter cartridge 2 away from the partition plate 4. Multiple filter cartridges 2 at their ends away from the partition plate 4 extend into multiple retaining rings 13. Of course, in other embodiments, the filter cartridge 2 can also be inclined within the filter chamber 11, which can be reasonably selected according to the actual situation.

[0031] Multiple end caps 3 are respectively provided in a one-to-one correspondence with multiple retaining rings 13, and the end caps 3 are placed over the corresponding retaining rings 13. Figure 4 Multiple clips 15 on the retaining ring 13 secure the end cap 3 to achieve a sealed connection between the end cap 3 and the retaining ring 13. Each end cap 3 is equipped with a sealing element 6, which, in conjunction with... Figure 5In this embodiment, the sealing element 6 includes a cylinder 61 and a sealing plate 62. The cylinder 61 is installed outside the end cover 3, and the sealing plate 62 is located inside the end cover 3. The piston rod 612 of the cylinder 61 passes through the end cover 3 and connects to the sealing plate 62. The cylinder 61 is connected to the high-pressure gas in the plant. The solenoid valve 611 of the cylinder 61 can change the air intake direction, thereby causing the telescopic rod of the cylinder 61 to extend or retract. The extension and retraction of the telescopic rod of the cylinder 61 can drive the sealing plate 62 to move inside the end cover 3. When the piston rod 612 of the cylinder 61 extends outward, it drives the sealing plate 62 to move towards the filter cartridge 2 to press against the filter cartridge 2, so that the other end of the filter cartridge 2 is pressed against the retaining ring 41, thus achieving the sealing of both ends of the filter cartridge 2. The high-pressure gas required by the cylinder 61 is generally available in industrial plants, and there are no high requirements for the type and purity of the high-pressure gas. It only needs to be non-toxic and non-corrosive, which is easy to obtain and has good universality.

[0032] To support the filter cartridge 2, multiple brackets 5 are horizontally arranged within the filter chamber 11, with each bracket 5 positioned below a different filter cartridge 2 to support it. In this embodiment, each bracket 5 includes two horizontally spaced support rods, with both ends of the rods connected to the partition plate 4 and the side wall of the housing 1, respectively. The distance between the two support rods is appropriately set according to the size of the filter cartridge 2. The connection between the two ends of the support rods to the partition plate 4 and the side wall of the housing 1 prevents deformation of the partition plate. In other embodiments, the bracket 5 can also be directly configured as an arc-shaped structure adapted to the filter cartridge 2, with the arc-shaped opening of the bracket 5 facing upwards. With the above structural configuration, when installing the filter cartridge 2, it is inserted into the filter chamber 11 through the second through hole 14. The filter cartridge 2 is supported by the bracket 5 and slides along the bracket 5 to engage with the second retaining ring 13.

[0033] In this embodiment of the filter cartridge dust collector, when installing each filter cartridge 2, the end cover 3 is first removed from the retaining ring 13, and the filter cartridge 2 is inserted into the filter chamber 11 through the through hole 14. The filter cartridge 2 is pushed so that it moves along the corresponding bracket 5 until it is inserted into the corresponding retaining ring 41 and contacts the partition 4. Then, the end cover 3 is clamped and fixed on the corresponding retaining ring 13 by rotating the multiple buckles 15 on the outer periphery of the retaining ring 13. The piston rod 612 of the cylinder 61 extends so that the sealing plate 62 abuts against the end of the filter cartridge 2, and also makes the other end of the filter cartridge 2 abut against the partition 4 for sealing, thus achieving a seal at both ends of the filter cartridge 2. The sealing performance is high, and the installation steps of the filter cartridge 2 are simplified.

[0034] In this embodiment, the cartridge dust collector is connected to an externally installed fan system through the air inlet 17 to introduce the dust-laden gas to be filtered into the filter chamber 11. After being filtered by the filter cartridge 2, the air enters the clean room 12 and is finally discharged from the air outlet 18. The dust hopper 16 is used to collect the filtered impurities.

[0035] When the filter cartridge dust collector of this embodiment needs to be replaced or cleaned after a period of use, simply retract the piston rod 612 of the cylinder 61 to move the sealing plate 62 away from the filter cartridge 2, and loosen the end cover 3 by rotating the multiple buckles 15. Then, remove the end cover 3 and take out the filter cartridge 2. This makes it easy to disassemble the filter cartridge 2, saves time and effort, is easy for workers to operate, is convenient for inspection and maintenance, and has low operation and maintenance costs.
