The internal support mechanism comprises a center rod 3, a support tube 4, a flexible sheet 5, a thrust bearing 6, a return spring 7, a push plate 8 and a spiral push tube 9. The center rod 3 is cooperatively installed inside the filter cartridge body 1, multiple groups of flexible sheets 5 are installed at the top of the support tube 4, the push plate 8 is installed at the other end of the multiple groups of flexible sheets 5, and the inner wall of the spiral push tube 9 is threadedly connected to the center rod 3. A thrust bearing 6 is provided between the push plate 8 and the spiral push tube 9, and a reset bearing is installed between the push plate 8 and the support tube 4. The quick clamping mechanism includes a clamping tube 10, a clamping rod 11, a locking groove 12 and a locking frame 13. The clamping rod 11 is movably extended into the interior of the clamping tube 10, and the locking groove 12 is arranged on the side of the clamping rod 11. The locking frame 13 is transversely penetrated and movably arranged on the side wall of the clamping tube 10, and one end of the locking frame 13 can be extended into the locking groove 12 to fix the clamping rod 11.

[0031] In this embodiment, the center rod 3 is installed inside the filter cartridge body 1, providing the main supporting structure. Multiple groups of flexible sheets 5 are installed on the top of the support tube 4 to stabilize the filter material and prevent it from excessive movement or deformation during the filtration process. The other end of the flexible sheet 5 is connected to the push plate 8, and the push plate 8 is moved by the adjustment of the spiral push tube 9. The push plate 8 compresses the flexible sheet 5 through the cooperation of the thrust bearing 6, and then the flexible sheet 5 is stretched open to stabilize the inside of the filter cartridge to adapt to different pressure and load conditions. The return spring 7 is installed between the push plate 8 and the support tube 4 to restore the push plate 8 to the initial position after the dust removal load is reduced to maintain the structural stability of the filter cartridge. The clamping rod 11 movably extends into the interior of the clamping tube 10. When the filter cartridge needs to be replaced or maintained, this design allows for quick clamping or unlocking of the filter cartridge, simplifying the operation process. The locking groove 12 is arranged on the side of the clamping rod 11, and the locking frame 13 is transversely penetrated and arranged on the side wall of the clamping tube 10. One end of the locking frame 13 can extend into the locking groove 12, that is, the locking movement is pulled by the clamping auxiliary mechanism, so that the locking frame 13 fixes the locking groove 12 position of the clamping rod 11, thereby ensuring the stability of the filter cartridge during operation.

[0032] The clamping auxiliary mechanism includes an adjustment tube 14, a movable inclined groove 15, a lateral block 16 and a moving groove 17. The lateral block 16 is installed on the side of the locking frame 13. The adjustment tube 14 is installed on the outer wall of the clamping tube 10 in cooperation with the directional rotation, and the moving groove 17 is arranged inside the adjustment tube 14, and the locking frame 13 moves relative to the adjustment tube 14 in the moving groove 17.

[0033] In this embodiment, the adjustment tube 14 is directional and rotatably mounted on the outer wall of the clamping tube 10, and the moving groove 17 is arranged inside the adjustment tube 14. The rotation of the adjustment tube 14 causes the lateral block 16 to move along the moving inclined groove 15. This movement pushes or pulls the locking frame 13 through the lateral block 16, thereby realizing the rapid movement of the locking frame 13, thereby quickly unlocking or locking the filter cartridge. The lateral block 16 is mounted on the side of the locking frame 13 and cooperates with the moving groove 17 in the adjustment tube 14. This configuration allows the lateral block 16 to push the locking frame 13 along the moving inclined groove 15 to perform a rapid locking or unlocking action under the rotation operation of the adjustment tube 14.

[0034] See also Figure 1-6 As a supplementary implementation method of a filter cartridge for a filter cartridge type dust collector for the internal support mechanism, the quick clamping mechanism and the clamping auxiliary mechanism: the top end surface of the adjustment tube 14 is provided with a top block 18, the guide rail is installed on the side of the clamping tube 10, and the inner side surface of the top block 18 is rotatably installed in cooperation with the guide rail, and lateral mounting frames 19 are provided on both sides of the mounting plate 2, and lateral plates 20 are provided on both sides of the top of the filter cartridge, and the mounting plate 2 is arranged and installed in the position to be installed inside the dust collector, and one end of the clamping rod 11 can extend into the lateral plate 20. A fixing plate 21 is provided at the bottom of the clamping tube 10, and the fixing plate 21 is fixedly mounted on the top end surface of the lateral mounting frame 19, a first locking tube 22 is provided at the top of the filter cartridge body 1, a second locking tube 23 is provided on the inner side surface of the mounting plate 2, and the first locking tube 22 can be rotationally locked with the second locking tube 23, a guide block 24 is provided on the side of the clamping rod 11, and a guide groove 25 is provided on the inner side surface of the clamping tube 10, a fixing frame 26 is provided at the bottom of the filter cartridge body 1, and one end of the support tube 4 and the center tube are mounted on the fixing frame 26.

[0035] More specifically, the fixing frame 26 and the lateral mounting frame 19 provide additional stability to ensure that the filter cartridge remains fixed inside the dust collector and will not shift due to vibration or operational errors. The interlocking design of the first locking tube 22 and the second locking tube 23 further ensures the stability of the filter cartridge during operation and prevents structural loosening due to vibration or pressure changes.

[0036] In summary, when the overall equipment is in use or running: when the operation of the internal support mechanism is required, the center rod 3 is installed inside the filter cartridge body 1, providing the main support structure, and multiple groups of flexible sheets 5 are installed on the top of the support tube 4 to stabilize the filter material and prevent it from excessive movement or deformation during the filtration process. The other end of the flexible sheet 5 is connected to the push plate 8, and the push plate 8 is moved by the adjustment of the spiral push tube 9. The push plate 8 compresses the flexible sheet 5 through the cooperation of the thrust bearing 6, and then the flexible sheet 5 is stretched open to stabilize the inside of the filter cartridge to adapt to different pressure and load conditions. The return spring 7 is installed between the push plate 8 and the support tube 4, and is used to restore the push plate 8 to the initial position after the dust removal load is reduced, so as to maintain the structural stability of the filter cartridge.

[0037] When the quick clamping mechanism is required to be operated, the clamping rod 11 is movable and extends into the interior of the clamping tube 10. When the filter cartridge needs to be replaced or maintained, this design allows for quick clamping or unlocking of the filter cartridge, simplifying the operation process. The locking groove 12 is arranged on the side of the clamping rod 11, and the locking frame 13 is arranged transversely through the side wall of the clamping tube 10. One end of the locking frame 13 can be extended into the locking groove 12, that is, the locking movement is pulled by the clamping auxiliary mechanism, so that the locking frame 13 fixes the locking groove 12 position of the clamping rod 11, ensuring the stability of the filter cartridge during operation.

[0038] When the operation of the clamping auxiliary mechanism is required, the adjustment tube 14 is directional and rotated to be installed on the outer wall of the clamping tube 10, and the moving groove 17 is arranged inside the adjustment tube 14. The rotation of the adjustment tube 14 causes the lateral block 16 to move along the moving inclined groove 15. This movement pushes or pulls the locking frame 13 through the lateral block 16, thereby realizing the rapid movement of the locking frame 13, thereby quickly unlocking or locking the filter cartridge. The lateral block 16 is installed on the side of the locking frame 13 and cooperates with the moving groove 17 in the adjustment tube 14. This configuration allows the lateral block 16 to push the locking frame 13 along the moving inclined groove 15 to perform a rapid locking or unlocking action under the rotation operation of the adjustment tube 14.

[0039] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
