When the industrial filter cartridge is used, it will also filter gases with a certain temperature. If it is in a high temperature environment for a long time, the surface of the filter cartridge will gradually become brittle or deformed, affecting its service life. Summary of the Invention

[0004] The problem to be solved by the present invention is that after long-term use, a lot of dirt adheres to the surface of the industrial filter cartridge, and the machine needs to be stopped to remove the filter cartridge for cleaning the dirt, which affects the working efficiency.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a high-temperature resistant industrial dust removal filter cartridge, comprising a filter cartridge, a reinforcement ring is provided on the surface of the filter cartridge, a top cover is provided on the top of the filter cartridge, a bottom plate is provided on the bottom of the filter cartridge, the interior of the filter cartridge is hollow, a metal frame is provided inside the filter cartridge, a plurality of cooling holes are pierced through the interior of the metal frame in a surrounding array, the interior of the cooling holes is conical, a top plate is provided on the top of the surface of the filter cartridge, a cleaning structure is provided on the bottom of the top plate, and a rotating structure is provided on the surface of the filter cartridge;

[0006] The cleaning structure includes four movable rods, two of which are fixed and the other two are movable.

[0007] The rotating structure includes an outer shell, which is split into upper and lower parts. The inner part of the outer shell is rotatably connected to a rotating seat. The outer wall of the outer shell is fixedly connected to the connecting block. An impeller is provided at the bottom of the rotating seat. The angle of the impeller is inclined. An impact rod is provided at the bottom of the rotating seat. A raised anti-sliding block is provided at the top of the rotating seat.

[0008] Preferably, a sleeve is provided at the bottom of the two movable rods, the bottom of the sleeve is fixedly connected to the top of the base plate, a limiting groove is opened on one side of the sleeve, one side of the limiting groove passes through a limiting block, and one side of the limiting block is fixedly connected to the bottom of the surface of the movable rod.

[0009] Preferably, the top of the movable rod passes through the top plate and extends to the outside of the top plate. A movable ring is provided on the top of the movable rod, and a movable groove is provided in the middle of the movable ring.

[0010] Preferably, the inner wall diameter of the movable groove is larger than the outer wall diameter of the top cover, and fixing screws are passed through the front and back of the movable ring, wherein the two movable rods are fixedly connected to the bottom of the movable ring.

[0011] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0012] (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. The impeller ensures rotation while the gap is large and 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, it can be controlled to move the movable rod upward. 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.

[0013] (2) The metal frame inside the filter cartridge has also been 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, avoiding 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

The interior of the cooling holes 12 is conical, a top plate 9 is provided on the top of the surface of the filter cartridge 5, a cleaning structure 3 is provided on the bottom of the top plate 9, and a rotating structure 6 is provided on the surface of the filter cartridge 5;

[0029] The cleaning structure 3 includes four movable rods 301, two of which are fixed and the other two are movable. The surfaces of the movable rods 301 are provided with rotating blocks 305 from top to bottom, the interior of the rotating blocks 305 is provided with a torque spring 307, and one side of the rotating blocks 305 is provided with an impact block 303. The surface of the movable rods 301 is provided with a plurality of connecting blocks 302 from top to bottom, two of which are fixed with connecting blocks 306 on the surface, and the bottom of the connecting blocks 306 is provided with a rubber block 304;

[0030] The rotating structure 6 includes an outer shell 602, which is split into upper and lower parts. The inner part of the outer shell 602 is rotatably connected to a rotating seat 604. The outer wall of the outer shell 602 is fixedly connected to the connecting block 302. An impeller 601 is provided at the bottom of the rotating seat 604. 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.

[0031] 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 the limiting block 10. One side of the limiting block 10 is fixedly connected to the bottom of the surface of the movable rod 301.

[0032] 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.

[0033] The inner wall diameter of the movable groove is larger than the outer wall diameter of the top cover 1 . Fixing screws 7 are passed through the front and back of the movable ring 2 , wherein the two movable rods 301 are fixedly connected to the bottom of the movable ring 2 .

[0034] 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 movable ring 2 to be in a locked state. The rubber block 304 will squeeze 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 movable ring 2 outward. , the moving ring 2 drives two of the movable rods 301 to move outward along the connecting block 302. When the movable rod 301 moves up, it drives the rubber block 304 to move upward. After the rubber block 304 detaches 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 movable rod 301 outward for a distance. At this time The impact block 303 that is in close contact with the surface of the filter cartridge 5 will drive the rotating block 305 to rotate with the rotating connection point with the movable rod 301 as the center of the circle, and will compress the torque spring 307 during the rotation. When the impact rod 603 is separated 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 rebound force 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 its surface, thereby performing a basic Clean, and when it is not needed in the future, restore the movable ring 2 to its original position to re-fix the impeller 601. 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 hole 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 blown to the other side can also cool the filter cartridge 5 body, further increasing the service life of the filter cartridge 5.

The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
