[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a reusable filter bag, comprising an installation ring 1 and a filter bag 2. The installation ring 1 has an internal sliding connection to a sealing mechanism, and a cleaning mechanism is fixedly connected to its bottom end. The installation ring 1 is the basic structure of the entire device, providing installation positions for other components. The internal sliding connection structure is used to install the sealing mechanism, and its bottom end is fixed to the cleaning mechanism. Through cooperation with other components, the normal installation, sealing, and cleaning functions of the filter bag 2 are ensured. The filter bag 2 has an internal filter layer 22 made of polyester needle-punched felt, which effectively filters impurities. A cleaning layer 23 made of fiberglass mesh is fixedly connected to the inner wall of the filter layer 22. Working in conjunction with the filter layer 22, the cleaning layer 23 better removes accumulated dust from the filter bag 2, extending its service life. Installation blocks 21 are fixedly connected to both the front and rear sides of the installation ring 1. The installation blocks 21 are used for the installation of the entire device, providing positions for connection to external equipment or structures.

[0034] The sealing mechanism includes two receiving plates 5, whose outer walls are slidably connected to the inner wall of the mounting ring 1. Each receiving plate 5 has a locking block 6 fixedly connected to a nearby side. The receiving plates 5 serve to connect and transmit force in the sealing mechanism, stably moving the locking blocks 6. Fixing plates 3 are fixedly connected to the top left and right sides of the filter bag 2, connecting the filter bag 2 to the sealing mechanism and ensuring its stable fixation within the mounting ring 1. This is a crucial connection structure for installing and fixing the filter bag 2. A square frame block 4 is fixedly connected to the top of the fixing plate 3, and the outer wall of the locking block 6 engages with the inner wall of the square frame block 4. The bottom left and right sides of the mounting ring 1 also have locking blocks. The top inner wall of the snap-fit ​​groove is fixedly connected to a sealing gasket 12. The outer wall of the square block 4 is slidably connected to the inner wall of the snap-fit ​​groove. When the filter bag 2 is installed, the square block 4 enters the snap-fit ​​groove and squeezes the snap-fit ​​block 6. When it is fully inserted into the snap-fit ​​groove and squeezes the sealing gasket 12, it provides conditions for the snap-fit ​​block 6 to reset and engage, thereby completing the installation and fixing of the filter bag 2. The top side of the square block 4 contacts the bottom side of the sealing gasket 12 to increase the sealing performance. Sliding cylinders 7 are fixedly connected to the far sides of the two receiving plates 5. Circular grooves are opened on both the left and right sides of the interior of the mounting ring 1. The outer wall of the sliding cylinder 7 is slidably connected to the inner wall of the circular groove, providing guidance and support for the movement of the snap-fit ​​block 6. A circular plate 8 is slidably connected to the inner wall of the sliding cylinder 7. A transmission rod 9 is fixedly connected to the opposite side of each circular plate 8. When the filter bag 2 is disassembled, the transmission rod 9 rotates, causing the circular plate 8 to move to both sides. The movement of the circular plate 8 causes the slide cylinder 7 to move, which in turn causes the locking block 6 to release the locking of the opposite frame block 4. It is an important transmission component in the disassembly process. The external threads of the two transmission rods 9 are connected to the left and right sides inside the mounting ring 1. The transmission rods 9 are fitted with return springs 10. The adjacent sides of the two return springs 10 are fixedly connected to the opposite sides of the two slide cylinders 7. The opposite sides of the two return springs 10 are fixedly connected to the inner walls of the opposite sides of the two circular grooves. When the filter bag 2 is installed, the locking block 6 moves and squeezes the return spring 10. When the frame block 4 enters the locking groove... Afterwards, the return spring 10 uses the pressure generated by compression to reset and engage the locking block 6, providing power for the reset of the locking block 6. Rotating plates 11 are fixedly connected to the far sides of the two transmission rods 9, and the near sides of the two rotating plates 11 are in contact with the left and right sides of the mounting ring 1. When the filter bag 2 is disassembled, the rotating plates 11 rotate and drive the transmission rods 9 to rotate. Due to the threaded connection, the circular plate 8 moves, thereby realizing the movement of the locking block 6. It is a key component for power transmission when disassembling the filter bag 2. A sealing ring 13 is fixedly connected to the top of the filter bag 2. The top side of the sealing ring 13 is in contact with the bottom side of the mounting ring 1 to increase the sealing performance and prevent gas from leaking from the connection between the filter bag 2 and the mounting ring 1 during the filtration process.

[0035] Reference Figure 1 , Figure 2 and Figure 4The dust removal mechanism includes multiple vertical plates 14, the tops of which are fixedly connected to the bottom of the mounting ring 1. Multiple support rings 15 are fixedly connected to the outside of the multiple vertical plates 14. The multiple vertical plates 14 provide a fixed position for the support rings 15, serving as support and connection, and connecting the mounting ring 1 to other components in the dust removal mechanism. The support rings 15 prevent the filter bag 2 from collapsing during use. Multiple air jet holes 16 are opened inside the support rings 15. The air jet holes 16 are used to blow air onto the inner wall of the filter bag 2 to achieve back-blowing dust removal. The outer wall of the support rings 15 is fixedly connected to an anti-wear layer 17. The anti-wear layer 17 is made of PTFE impregnated glass fiber cloth. The outer wall of the multiple anti-wear layers 17 is in contact with the inner wall of the filter bag 2, which can reduce the friction between the support rings 15 and the filter bag 2, prevent the filter bag 2 from being worn, protect the filter bag 2, and at the same time ensure the supporting function of the support rings 15 for the filter bag 2. Multiple vertical plates 14 are fixedly connected to adjacent sides of air supply pipes 18. The top of multiple air supply pipes 18 is fixedly connected to an annular pipe 19. The outer wall of the annular pipe 19 is fixedly connected to the inner wall of the mounting ring 1. The top of the annular pipe 19 is fixedly connected to an air inlet pipe 20, which is used to supply airflow to the annular pipe 19 to provide an air source for the entire dust removal process. The annular pipe 19 plays the role of collecting and distributing airflow, distributing the airflow entering from the air inlet pipe 20 to multiple air supply pipes 18. The air supply pipe 18 delivers the airflow in the annular pipe 19 to the jet hole 16 in the support ring 15, which is the channel for airflow transmission, ensuring that the airflow can accurately reach the jet hole 16 during backflushing dust removal.

[0036] Working principle: When installing filter bag 2, by attaching the sealing ring 13 on filter bag 2 to the bottom side of the mounting ring 1, the fixing plates 3 on both sides of filter bag 2 will drive the square frame block 4 to move into the snap-fit ​​groove. During this process, the square frame block 4 will squeeze the snap-fit ​​block 6, causing it to move to both sides. The moving snap-fit ​​block 6 will drive the receiving plate 5 and the slide cylinder 7 to move and squeeze the return spring 10. When the square frame block 4 is fully inserted into the snap-fit ​​groove and squeezes the sealing gasket 12, the snap-fit ​​block 6 will lose the squeezing of the square frame block 4 and will be reset by the pressure generated by the compression of the return spring 10 and will snap into place with the square frame block 12. The internal locking mechanism of block 4 completes the installation of filter bag 2. The sealing ring 13 and sealing gasket 12 are used to increase the sealing performance. When filter bag 2 needs to be removed for replacement or cleaning, the rotating plate 11 is rotated to drive the transmission rod 9 to rotate. Since the transmission rod 9 and the mounting ring 1 are threadedly connected, the rotation of the transmission rod 9 drives the circular plate 8 to rotate and move to both sides. This movement of the circular plate 8 drives the sliding cylinder 7 to move to both sides. Finally, the locking block 6 releases the locking limit of the opposite frame block 4, completing the disassembly of filter bag 2.

[0037] The vertical plate 14 and the support ring 15 provide stable support for the filter bag 2. The anti-wear layer 17 on the outside of the support ring 15 can reduce friction on the filter bag 2. By delivering airflow into the air inlet pipe 20, the airflow enters multiple air delivery pipes 18 through the annular pipe 19. Finally, the airflow blows air onto the inner wall of the filter bag 2 through the jet hole 16 to achieve back-blowing and dust removal, cleaning the dust accumulated on the filter bag 2. At the same time, in conjunction with the functions of the filter layer 22 and the cleaning layer 23, the overall service life of the filter bag 2 is increased.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
