[0002] Since their introduction, dust collectors have been widely used and improved both domestically and internationally, achieving significant progress in both dust-laden gas purification performance and equipment structure. Currently, top-mounted cartridge dust collectors are mostly screw-fastened, with some featuring an angled insertion. This requires a large space above the dust collector, and is typically installed outdoors. To protect against rain and snow, this requires the construction of a building, which increases equipment costs. Furthermore, dust collectors with a large number of cartridges require screw-fastening, significantly increasing labor costs. There's also the risk of screws or nuts falling into the dust collector, damaging the conveying equipment below. Indoor installations are limited by height, presenting significant limitations. While angled insertion requires no space above the dust collector, dust accumulated on the upper surface of the cartridge cannot be cleaned with compressed air backwashing, requiring manual cleaning, a time-consuming and labor-intensive process.

[0003] For the above-mentioned several existing filter cartridge structures, the filter cartridge is usually fastened with screws during installation, which increases labor costs. At the same time, there is a risk that screws or nuts may fall into the interior of the filter cartridge, causing damage to the conveying equipment below the filter cartridge. Therefore, a bottom-mounted filter cartridge clamping mechanism is urgently needed. Utility Model Content

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Reference Figures 1 to 4 The utility model provides a bottom-mounted filter cartridge pressing mechanism for pressing a filter cartridge 500 onto a frame 600. The filter cartridge 500 includes a tray 5001 and a cartridge body 5002. The tray 5001 is provided with a snap-fit ​​groove 50011 for sleeve-mounting the cartridge body 5002. The pressing mechanism includes at least two sets of pressing components 1.

[0037] At least two groups of the pressing assemblies 1 are arranged at intervals on the frame 600; the pressing assembly 1 includes a support frame 11 and a crimping member 12, the support frame 11 is arranged on the frame 600, and the crimping member 12 is arranged on the support frame 11 for crimping the filter cartridge 500 to the frame 600.

[0038] When the barrel body 5002 is sleeved in the engaging groove 50011 , the crimping member 12 has a first state in which the tray 5001 is crimped to the frame 600 and a second state in which the tray 5001 is released from the crimping to the frame 600 .

[0039] The bottom-mounted filter cartridge clamping mechanism provided by the present invention is provided with components such as the support frame 11 and the crimping piece 12. In actual application, the cartridge body 5002 is first sleeved on the clamping groove 50011, and then the crimping piece 12 is adjusted to the first state, so that the crimping piece 12 can crimp the tray 5001 to the frame 600, and the cartridge body 5002 can be stably clamped in the set space. When the cartridge body 5002 needs to be removed for cleaning, the crimping piece 12 can be adjusted to the second state, so that the crimping piece 12 can release the crimping of the tray 5001, and then the cartridge body 5002 can be taken out of the clamping groove 5001 for cleaning. By providing the above-mentioned structure, the present invention can stably and quickly install or disassemble the cartridge body 5002, and does not adopt screw fastening method, which can reduce labor costs and no screws or nuts will fall into the interior of the filter cartridge 500, so that the lower conveying equipment of the filter cartridge 500 is safe.

[0040] Among them, when the cylinder body 5002 is sleeved on the clamping groove 50011, the clamping groove 50011 can limit the downward movement of the cylinder body 5002. When the crimping part 12 crimps the tray 5001 to the frame 600, the tray 5001 and the frame 600 can limit the upward movement of the cylinder body 5002. Therefore, through the cooperation of the tray 5001 and the clamping assembly 1, the cylinder body 5002 can be stably clamped in the set space.

[0041] Special note: Bottom-mounted filter cartridge 500‌ refers to an installation method in which the filter cartridge 500 is installed upwards from the bottom of the mounting plate and then fixed to the mounting plate.‌

[0042] In order to stably clamp the barrel body 5002, the crimping member 12 includes a rotating member 121 and a pressing cam 122. The rotating member 121 is rotated to the support frame 11, and the pressing cam 122 is located on the outside of the rotating member 121. The rotating member 121 is used to drive the pressing cam 122 to rotate and press the tray 5001 to the frame 600, so that the crimping member 12 can switch between the first state and the second state. Each rotating member 121 is sequentially rotated to at least two of the support frames 11. Each rotating member 121 is sequentially rotated to three of the support frames 11. By providing the rotating member 121 and the pressing cam 122, the rotating member 121 is rotated to drive the pressing cam 122 to rotate and press the tray 5001 to the frame 600, so that the crimping member 12 can switch between the first state and the second state, thereby stably clamping the barrel body 5002.

[0043] To facilitate rotation of the rotating members 121, each rotating member 121 has a screwing end 1211 extending outward from the support frame 11 through which it passes, and a screwing nut 2 is provided at the end of the screwing end 1211. In practice, the rotating member 121 is rotated with a torque wrench to drive the pressing cam 122 to rotate and press the tray 5001 against the frame 600, allowing the pressing member 12 to switch between the first and second positions, thereby stably clamping the barrel body 5002.

[0044] To ensure stable engagement of the barrel body 5002, a stopper plate 3 is fixed to the side wall of the support frame 11 near the screwing end 1211. The screwing end 1211 is rotatably mounted on the stopper plate 3, and the stopper plate 3 is used to limit the axial travel of the corresponding rotating member 121. This design reduces the axial travel of the rotating member 121, prevents the rotating member 121 from deviating too far in the axial direction, and ensures stable engagement of the barrel body 5002.

[0045] In order to further stably clamp the barrel body 5002, each of the crimping members 12 includes a plurality of clamping cams 122, which are sequentially arranged on the outer side of the rotating member 121 along the axial direction of the corresponding rotating member 121. This design results in more crimping points on the tray 5001, making the crimping surface 1221 larger. When one of the clamping cams 122 fails, the other clamping cams 122 can still crimp the tray 5001 to the frame 600, thereby further stably clamping the barrel body 5002. As a preferred embodiment, the plurality of clamping cams 122 are sequentially arranged at equal intervals on the outer side of the rotating member 121 along the axial direction of the corresponding rotating member 121. As another preferred embodiment, the plurality of clamping cams 122 are sequentially arranged at non-equal intervals on the outer side of the rotating member 121 along the axial direction of the corresponding rotating member 121.

[0046] To facilitate switching the working state of the crimping member 12, the pressing cam 122 includes a curved crimping surface 1221 and a flat locking surface 1222. The crimping surface 1221 and the locking surface 1222 are smoothly connected. When the crimping member 12 switches from the second state to the first state, the crimping surface 1221 is used to roll and crimp the tray 5001, and the locking surface 1222 is used to crimp the tray 5001 to the frame 600. This design allows the crimping member 12 to switch between the first and second states more smoothly, facilitating practical use.

[0047] Working principle: first, the cylinder body 5002 is placed on the clamping groove 50011, and then the crimping part 12 is adjusted to the first state, so that the crimping part 12 can crimp the tray 5001 to the frame 600, and can stably clamp the cylinder body 5002 in the set space. When the cylinder body 5002 needs to be removed for cleaning, the crimping part 12 can be adjusted to the second state, so that the crimping part 12 can release the crimping of the tray 5001, and then the cylinder body 5002 can be taken out of the clamping groove 50011 for cleaning.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
