[0002] The filter cartridge is a cylindrical element used for filtering. It is generally divided into filter cartridges used to filter gas media and filter liquid media. At the same time, in order to increase the filtering area, the corresponding pleated filter cartridge is generally used;

[0003] However, the existing dust filter cartridges are not able to block and limit the dust inside the filter cartridges when in use, so the dust inside the filter cartridges is easy to escape. At the same time, when using the filter cartridges, most of them use a cleaning structure to clean the filter cartridges, but since the cleaning structure cannot be disassembled and replaced, the filter cartridges cannot be cleaned regularly when the cleaning structure is damaged, which reduces the working efficiency of the filter cartridges. To this end, we provide a multi-purpose pleated dust filter cartridge to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-6 The utility model is a multi-purpose pleated dust filter cartridge. The conical cylinder 5 is located inside the pleated filter cartridge 1 to block and limit the objects inside the pleated filter cartridge 1 to prevent dust from escaping from the hanging ring 501. At the same time, the movement of the telescopic rod 304 can facilitate the disassembly and replacement of the dust removal half ring 2.

[0030] Specifically, a pleated filter cartridge 1; a top plate 3 is arranged directly above the pleated filter cartridge 1, a shelf opening 307 is opened in the middle of the upper surface of the top plate 3, a conical cylinder 5 is arranged inside the pleated filter cartridge 1, a hanging ring 501 located inside the shelf opening 307 is fixed to the upper end of the conical cylinder 5, two symmetrically arranged dust removal semi-rings 2 are sleeved on the circumference of the pleated filter cartridge 1, and a limit rod 301 is fixed at the lower end of the top plate 3 corresponding to the position of the dust removal semi-ring 2, and the dust removal semi-ring 2 passes The sliding hole 202 provided on the upper end surface is slidably sleeved on the limit rod 301, and the lower end of the limit rod 301 is provided with a retraction hole 302. A bottom plate 4 is provided just below the pleated filter cartridge 1, and a positioning rod 401 is fixed at the position of the upper surface of the bottom plate 4 corresponding to the limit rod 301. A telescopic rod 304 connected to the upper end surface of the positioning rod 401 is provided inside the retraction hole 302, and a cleaning plate 201 matching the side surface of the pleated filter cartridge 1 is fixed to the inner side of the dust removal half ring 2.

[0031] The operation process of this embodiment is as follows: through the arrangement and use of the above structure, after the top plate 3 and the bottom plate 4 are installed at the upper and lower end positions of the pleated filter cartridge 1, the conical cylinder 5 can be arranged at the position of the shelf opening 307, so that the hanging ring 501 is located at the position of the shelf opening 307, and then when in use, the air to be dusted can enter from the position of the hanging ring 501, so that the air to be dusted can fall from the position of the conical cylinder 5 into the pleated filter cartridge 1, so that the conical cylinder 5 can block and limit the objects inside the pleated filter cartridge 1, preventing dust from falling from the hanging ring 501. The ring 501 is out of position. When the dust removal half ring 2 needs to be disassembled and replaced, the two dust removal half rings 2 can be disassembled, and the telescopic rod 304 is moved upward to make it disengaged from the positioning rod 401, so that the dust removal half ring 2 can be disengaged from the position between the positioning rod 401 and the telescopic rod 304, and the dust removal half ring 2 can be replaced. At the same time, when the dust removal half ring 2 is used, the dust removal half ring 2 can be directly moved up and down, and then the dust removal half ring 2 will drive the cleaning plate 201 to clean the dirt on the surrounding side of the pleated filter cartridge 1. Specific embodiment 2

[0033] See also Figure 3 , 5 6. Based on the specific embodiment 1, the outer screw ring 601 is screwed into the inner position of the inner screw hole 308, so that the assembly ring 6 can limit the hanging ring 501, so that the conical tube 5 can be stably located in the inner position of the pleated filter tube 1.

[0034] Specifically, a concave ring opening 502 is provided on the upper part of the peripheral side of the hanging ring 501, and an assembly ring 6 is rotatably sleeved inside the concave ring opening 502. An inner threaded opening 308 is provided on the upper end surface of the top plate 3 outside the resting opening 307, and an outer threaded ring 601 spirally connected to the inner threaded opening 308 is fixed on the peripheral side of the assembly ring 6. Mounting rings 101 are fixed on the upper and lower ends of the pleated filter cartridge 1, and an assembly rod 102 is fixed on the other end surface of the mounting ring 101 opposite to the pleated filter cartridge 1, and the assembly rod 102 is respectively bolted to the adjacent top plate 3 and bottom plate 4.

[0035] The operation process of this embodiment is as follows: when it is necessary to disassemble the conical tube 5, the assembly ring 6 can be directly rotated, so that the assembly ring 6 can drive the outer screw ring 601 to be screwed out from the internal position of the inner screw mouth 308, and then the assembly ring 6 will no longer limit the hanging ring 501. At this time, the hanging ring 501 is taken out from the inside of the shelf mouth 307, and the conical tube 5 can be replaced. At the same time, when the outer screw ring 601 is screwed into the internal position of the inner screw mouth 308, the outer screw ring 601 will drive the assembly ring 6 to move to the internal position of the concave ring mouth 502, so that the assembly ring 6 abuts against the hanging ring 501 and limits it. Specific embodiment three

[0037] See also Figure 2 , 4 6. Based on the specific embodiment 1, the spring 306 pushes the telescopic rod 304 so that the telescopic rod 304 is in the retraction hole 302 and does not move up and down at will.

[0038] Specifically, connecting plates 203 are fixed to both ends of the dust removal half ring 2, and two adjacent connecting plates 203 are connected by bolts. A spring 306 is fixed to the other end of the telescopic rod 304 opposite to the positioning rod 401, and the other end of the spring 306 is fixed to the inner end surface of the retraction hole 302. Two symmetrically arranged adjustment openings 303 are provided on the circumferential side of the limit rod 301, and an adjustment block 305 that slides inside the adjustment opening 303 is fixed to the circumferential side of the telescopic rod 304 inside the retraction hole 302.

[0039] The operation process of this embodiment is as follows: when the telescopic rod 304 is moved to the internal position of the retraction hole, the telescopic rod 304 will compress the spring 306. At the same time, in order to facilitate the movement of the telescopic rod 304, the adjustment block 305 can be directly controlled to slide along the position of the adjustment port 303, and then the adjustment block 305 will directly drive the telescopic rod 304 to move. When the adjustment block 305 is released, the telescopic rod 304 will automatically slide down and push the telescopic rod 304 through the spring 306, so that the telescopic rod 304 can be stably connected with the positioning rod 401.
