The filter disc 4 produces too much obstruction; the dust collecting sleeve 5 is provided with bristles 6 connected to the bottom of the filter disc 4; the dust collecting sleeve 5 is provided with dust collecting holes, and the dust collecting sleeve 5 is conductively connected with the dust collecting box 7 arranged outside the tank body 1, and the dust collecting box 7 is provided with a dust suction fan 8, and a protective mesh cover is provided at the dust suction fan 8 to ensure that the adsorbed dust and impurities are trapped in the dust collecting box 7. A door panel is hinged on one side of the dust collecting box 7 so that it can be opened regularly to clean the dust inside; in order to improve the convenience of cleaning, the dust collecting box 7 can be arranged under the tank body 1, and the dust collecting box 7 and the dust collecting sleeve 5 are conductively connected by a pipe; the specific selection can be made according to the matching of actual working conditions. When cleaning work is required, the motor 3 drives the driving gear to rotate, and the driving gear meshes with the end face toothed disc 2 to rotate, and at the same time drives the filter disc 4 to rotate. The filter disc 4 rotates and contacts and rubs with the bristles 6 below. Since the gas usually moves from bottom to top, the dust and impurities adsorbed on the bottom surface of the filter disc 4 are removed, and under the suction force of the dust suction fan 8, the removed dust is sucked into the dust collection box 7 for temporary storage. The whole process does not require disassembly of the equipment, which greatly improves the convenience of cleaning the filter disc 4.

[0024] Furthermore, in the present embodiment, a receiving groove 9 is provided at the top end of the dust collecting sleeve 5 along its length direction, the bristles 6 are arranged in the middle of the receiving groove 9 along the length direction of the receiving groove 9, and the dust collecting hole is arranged in the receiving groove 9; the bristles 6 are arranged in the middle of the receiving groove 9 to ensure that dust falls into the receiving groove 9 during the cleaning process; in addition, the dust collecting sleeve 5 is preferably arranged as a cylindrical structure to facilitate the movement of gas along the curved surface of the dust collecting sleeve 5, thereby playing a role in guiding the gas to be filtered.

[0025] Furthermore, a mounting ring 10 is provided inside the tank body 1, the end face toothed disc 2 is rotatably provided on the mounting ring 10, and the dust collecting sleeve 5 is provided on the mounting ring 10; the end face toothed disc 2 can be rotatably provided on the mounting ring 10 through a bearing, or can be provided in other ways; as in the present embodiment, a convex edge 11 is provided inside the mounting ring 10 along its circumferential direction, and an annular movable groove 12 is provided on the convex edge 11, and a ball is movably provided at the bottom of the end face toothed disc 2, and the end face toothed disc 2 can be movably located in the movable groove 12 through the ball; in order to ensure the stability of the end face toothed disc 2, a guide rod can be provided on its side wall, and a guide groove is provided on the side of the mounting ring 10, so that the end face toothed disc 2 can be guided and limited to ensure the stability of the end face toothed disc 2. Among them, the top surface of the convex edge 11 is lower than the top surface of the mounting ring 10, and a threaded hole can be set on the side of the mounting ring 10 on the upper part of the convex edge 11, which is used to fix the mounting ring 10 to the inner wall of the tank body 1; in addition, an annular protective cover 13 is detachably provided on the top of the mounting ring 10 by bolts, and the protective cover 13 is used to limit the position of the gear. A groove 14 is opened through the protective cover 13 at a position opposite to the gear, so that the driving gear can engage with the end face toothed disc 2 through the groove 14; wherein the ring width of the protective cover 13 is equal to the sum of the ring width of the mounting ring 10 and the ring width of the end face toothed disc 2, so as to ensure that the end face toothed disc 2 is protected while avoiding blocking the filter disc 4.

[0026] In the present embodiment, by controlling the rotation of the filter disc 4, the regular conversion of different filtering positions on the filter disc 4 can be realized. When the airflow is uneven, each filtering surface can be rotated to a different position for filtering to ensure the filtering effect. In addition, in the present embodiment, only the end face tooth disc 2 needs to be controlled to drive the filter disc 4 to rotate in a circle without requiring high precision. Therefore, if the diameter of the tank body 1 is large, the mounting ring 10, the end face tooth disc 2 and the filter disc 4 can be set as a split structure.

[0027] Furthermore, the filter disc 4 of the present embodiment is provided with a plurality of mounting holes at intervals, and a filter cartridge 15 is arranged in the mounting hole. Filter fillers can be added to the filter cartridge 15, so that while the bottom thereof is utilized to filter dust, the fillers inside the filter cartridge 15 can also be utilized to filter and remove other components in the gas; the bottom of the filter cartridge 15 is a mesh structure, and is flush with the bottom surface of the filter disc 4, so as to facilitate cleaning of the bottom thereof, and the top end of the filter cartridge 15 protrudes from the top surface of the filter disc 4, and the protruding portion is a mesh structure to increase the area for gas outflow.

[0028] An annular positioning groove is provided on the inner wall of the mounting hole, and a mounting groove is provided on the filter disc 4, which is in communication with the inside of the positioning groove. The positioning groove and the mounting groove are not shown in the figure; a positioning block 16 is provided on the filter cartridge 15, and the positioning block 16 can be inserted into the positioning groove through the mounting groove. Then, the positioning block 16 and the mounting groove can be misaligned by rotating the filter cartridge 15, so as to realize the rapid installation of the filter cartridge 15, facilitate the subsequent targeted maintenance and replacement of the filter cartridge 15, and avoid the cost waste caused by the need to replace all of them when the filter cartridge 15 is integrated. In addition, a sealing ring 17 is provided on the filter cartridge 15 above the positioning block 16, and the diameter of the sealing ring 17 is greater than the sum of the diameter of the mounting hole and the length of the mounting groove, so as to seal the mounting hole; in this embodiment, the filter cartridge 15 is preferably set as a split structure, and the split parts are connected by threads to facilitate disassembly for the replacement of the filler. In this embodiment, the filter cartridge 15 is a two-piece structure, the bottom of which is a mesh structure for filtering the gas in and out, the part located in the mounting hole is a sealing structure, and the part protruding from the mounting hole is a mesh structure; wherein the sealing ring 17 is integrated with the sealing section below the filter cartridge 15, and the sealing section is detachably connected to the mesh section above by threads.

[0029] When the utility model is in use, the mounting ring 10 is first mounted on the inner wall of the tank body 1, and then the end face toothed disc 2 and the filter disc 4 are mounted. After working for a period of time, the machine can be briefly stopped or the gas flow rate can be reduced. The motor 3 is started to drive the driving gear to engage the end face toothed disc 2 for transmission. At this time, the filter disc 4 will rotate synchronously. As the filter disc 4 rotates, it will contact and rub with the bristles 6 at the lower end to realize the cleaning operation of the dust at the bottom thereof. At this time, the dust swept by the dust suction fan 8 is sucked into the dust collecting box 7 for centralized temporary storage. The structure is simple and the operation is easy. The difficulty of cleaning the filter disc 4 is greatly reduced, and the work efficiency is guaranteed.
