[0014] (1) The filter cartridge is provided with a rotating structure and a cleaning structure, which can be used in conjunction with each other to allow the filter cartridge to filter the gas while allowing the gas to drive the impeller to rotate, and the impact block is lifted by the impact rod and then the surface of the filter cartridge is knocked by the rebound of the impact block, so that the dirt on the surface of the filter cartridge falls off and the service life of the filter cartridge is extended. The rotation of the impeller is driven by the incoming gas and does not require an additional power source, which is more energy-saving and environmentally friendly. While the impeller ensures rotation, the large gap will not hinder the normal use of the filter cartridge. When the filter cartridge does not need to be cleaned in the early stage, the rotating seat can be fixed by the rubber block on the movable rod. The fixed impeller is in a stationary state. When it is used later, the movable rod can be controlled to move up. The operation is simple and convenient. It can be directly controlled manually without turning on the machine, and there is no need to stop the machine to affect normal operation;

[0015] (2) The metal frame inside the filter cartridge is also improved. The mesh inside the metal frame is adjusted to a conical through hole. When encountering a high hot air flow during industrial dust removal, the conical mesh increases the flow rate when passing through the metal frame to assist in cooling it to a certain extent, thereby preventing the filter cartridge from being used under high-temperature airflow for a long time. During later maintenance, the metal frame can be replaced by removing the top and bottom plates of the filter cartridge. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The cleaning structure 3 includes four movable rods 301, two of which are fixed and the other two are movable. Rotating blocks 305 are provided on the surface of the movable rods 301 from top to bottom, and torque springs 307 are provided inside the rotating blocks 305. An impact block 303 is provided on one side of the rotating block 305.

[0032] A plurality of connecting blocks 302 are arranged on the surface of the movable rod 301 from top to bottom, wherein connecting blocks 306 are fixedly arranged on the surfaces of two movable rods 301 , and a rubber block 304 is arranged at the bottom of the connecting block 306 .

[0033] A sleeve 11 is provided at the bottom of the two movable rods 301, and the bottom of the sleeve 11 is fixedly connected to the top of the base plate 4. A limiting groove is provided on one side of the sleeve 11, and one side of the limiting groove passes through a limiting block 10. One side of the limiting block 10 is fixedly connected to the bottom of the surface of the movable rod 301.

[0034] The top of the movable rod 301 passes through the top plate 9 and extends to the outside of the top plate 9. A movable ring 2 is provided on the top of the movable rod 301, and a movable groove is provided in the middle of the movable ring 2.

[0035] The inner wall diameter of the movable groove is larger than the outer wall diameter of the top cover 1 . Fixing screws 7 penetrate the front and back sides of the movable ring 2 , wherein the two movable rods 301 are fixedly connected to the bottom of the movable ring 2 .

[0036] The rotating structure 6 includes a shell 602 , which is split into upper and lower parts. The inside of the shell 602 is rotatably connected to a rotating seat 604 , and the outer wall of the shell 602 is fixedly connected to the connecting block 302 .

[0037] An impeller 601 is provided at the bottom of the rotating seat 604 , and the angle of the impeller 601 is inclined. An impact rod 603 is provided at the bottom of the rotating seat 604 , and a raised anti-sliding block is provided at the top of the rotating seat 604 .

[0038] The working principle and use process of the present invention are as follows: when using, the user installs the filter cartridge 5 into the device that needs to filter the gas. After putting it in, the top plate 9 and the bottom plate 4 bear the force. When the filter cartridge 5 is used for a short time, the surface is relatively clean. The two movable rods 301 cooperate with the moving ring 2 to be in a locked state. The rubber block 304 squeezes the top of the rotating seat 604 to keep the impeller 601 in a stationary state. The filter cartridge 5 performs normal filtering operations. When the impurities on the surface of the filter cartridge 5 need to be cleaned after long-term use, the fixing screws 7 can be loosened to pull the moving ring 2 outward. , the moving ring 2 drives two of the moving rods 301 to move outward along the connecting block 302. When the moving rod 301 moves up, it drives the rubber block 304 to move upward. After the rubber block 304 is separated from the top of the rotating seat 604, the impeller 601 will rotate as the gas enters. The impeller 601 will drive the rotating seat 604 to rotate along the shell 602, and the impact rod 603 at the bottom of the rotating seat 604 will also rotate synchronously. When the impact rod 603 rotates, it will push the impact block 303 on the moving rod 301 outward for a distance. At this time The impact block 303 which is in close contact with the surface of the filter cartridge 5 will drive the rotating block 305 to rotate with the rotating connection with the movable rod 301 as the center, and will compress the torque spring 307 during the rotation. When the impact rod 603 is detached from the impact block 303, the torque spring 307 will control the impact block 303 to quickly return to the initial position through its own resilience and impact the surface of the filter cartridge 5. The force caused by the impact will not damage the body of the filter cartridge 5, and the vibration generated can shake off the dust and dirt attached to the surface, thereby performing a basic Clean, and restore the movable ring 2 to its original position when it is not needed in the future, so that the impeller 601 can be re-fixed. The whole operation can also be completed when the machine is running, which will not affect the normal operating efficiency. When the gas with a certain amount of heat passes through the filter cartridge 5, it will pass through the metal frame 13 after filtration. The conical cooling holes 12 set on the metal frame 13 will increase the flow rate of the gas, thereby reducing part of the heat and the gas with increased flow rate can be blown on the other side to cool the filter cartridge 5 body, thereby further increasing the service life of the filter cartridge 5.
