[0019] 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.

[0020] Example: Figures 1-6As shown, this utility model provides a filter element for a dust collector with replaceable filter paper, including a limiting mechanism 1. An annular filter paper 2 is detachably sleeved on the limiting mechanism 1. The limiting mechanism 1 includes a lower cover 11, with a mesh barrel 12 fixedly inserted into the inner side of the lower cover 11. An upper cover 13 is detachably sleeved on the top of the mesh barrel 12. Gear rings 14 for cooperation are fixedly installed on the inner walls of both the upper cover 13 and the lower cover 11, and rubber toothed rings 15 are fixedly installed on the outer wall of the gear rings 14. The lower cover... Both the inner sides of the cover 11 and the top cover 13 are fixedly installed with rubber toothed rings 16 that cooperate with rubber toothed rings 15. The annular filter paper 2 can be movably sleeved on the outside of the mesh barrel 12, and both ends of the annular filter paper 2 can be slidably sleeved on the outside of the rubber toothed rings 15. The ends of the annular filter paper 2 can be in close contact with the rubber toothed rings 16. The upper end of the mesh barrel 12 is slidably inserted with symmetrically arranged insert rods 17, and the opposite ends of the insert rods 17 are fixedly connected with pull plates 18. Springs 19 are fixedly installed on both opposite sides of the mesh barrel 12, and the ends of the springs 19 are fixedly connected to the mesh barrel 12. Symmetrically distributed insertion holes are provided on the inner wall of the top cover 13, and the insertion rods 17 can be slidably inserted into the insertion holes. Symmetrically arranged insertion blocks 111 are integrally formed on the inner bottom of the top cover 13, and the insertion blocks 111 are staggered with the insertion holes. The insertion blocks 111 can be slidably inserted into the top of the mesh barrel 12. Symmetrically distributed slots 112 are provided at the top of the mesh barrel 12, and the insertion blocks 111... 11 can be slidably inserted into slot 112. The cooperation between the insert 111 and slot 112 ensures the precise and stable engagement of the top cover 13 and the mesh barrel 12. The upper end of the mesh barrel 12 is provided with symmetrically arranged sliding holes 113, and the insert rod 17 is slidably inserted into the sliding holes 113. The opposite sides of the pull plate 18 are fixedly installed with levers 114, and the outer wall of the lever 114 is covered with a layer of anti-slip texture. The anti-slip texture can increase friction and facilitate operation.

[0021] By adopting the above technical solution, after the dust removal equipment has been used for a period of time, the user can remove the filter element and move the two levers 114 in opposite directions, thereby driving the two pull plates 18 to move in opposite directions, which in turn drives the two insertion rods 17 to move in opposite directions and stretches the corresponding springs 19. When the insertion rods 17 are completely separated from the corresponding insertion holes, the levers 114 are stopped and the top cover 13 is completely separated from the corresponding mesh barrel 12. Then, the used annular filter paper 2 is removed from the corresponding mesh barrel 12, and another new annular filter paper 2 is placed on the corresponding mesh barrel 12. After that, the new annular filter paper 2 is removed from the mesh barrel 12. The bottom end of the filter paper 2 is fitted over the corresponding toothed ring 14 and the rubber toothed ring 15, and its end is fitted with the corresponding rubber toothed ring 16. Then, the insert block 111 on the top cover 13 is inserted into the corresponding slot 112, and the top end of the new annular filter paper 2 is fitted over the corresponding toothed ring 14 and the rubber toothed ring 15. Then, the lever 114 is turned again and the insert block 111 is slid to the other end of the corresponding slot 112. At this time, the lever 114 is released again, and then the insert rod 17 will be inserted into the corresponding insertion hole. At this time, the other end of the new annular filter paper 2 will be tightly fitted with the corresponding rubber toothed ring 16.

[0022] The inner side of the limiting mechanism 1 is provided with a cleaning mechanism 3 for use. The cleaning mechanism 3 includes a rotating rod 31, which is rotatably inserted into the middle of the lower cover 11. A frame brush 32 that is used to cooperate with the inner wall of the mesh barrel 12 is fixedly sleeved on the outer side of the rotating rod 31. A rotating hole 110 is opened through the middle of the lower cover 11, and the rotating rod 31 is rotatably inserted into the rotating hole 110. The setting of the rotating hole 110 provides a guarantee for the stable rotation of the rotating rod 31. A handwheel 33 is fixedly installed at the bottom end of the rotating rod 31, and a rocker arm 34 is rotatably inserted into the handwheel 33.

[0023] By adopting the above technical solution, the rocker arm 34 can be turned before installing the new annular filter paper 2, which can drive the handwheel 33 to rotate, which in turn can drive the rotating rod 31 to rotate, and further drive the frame brush 32 to rotate, thereby making it easy to clean the impurities attached to the inner wall of the mesh barrel 12.

[0024] Working principle: After the dust removal equipment has been used for a period of time, the user can remove the filter element and move the two levers 114 in opposite directions, which will drive the two pull plates 18 to move in opposite directions, thereby driving the two insertion rods 17 to move in opposite directions and stretching the corresponding springs 19. When the insertion rods 17 are completely separated from the corresponding insertion holes, stop moving the levers 114 and completely separate the top cover 13 from the corresponding mesh barrel 12. Then, remove the used annular filter paper 2 from the corresponding mesh barrel 12, and then put another new annular filter paper 2 on the corresponding mesh barrel 12. After that, put the new annular filter paper 2 on the corresponding mesh barrel 12. The bottom end is fitted onto the outside of the corresponding toothed ring 14 and the rubber toothed ring 15, and its end is fitted with the corresponding rubber toothed ring 16. Then, the insert block 111 on the top cover 13 is inserted into the corresponding slot 112 and the top end of the corresponding new annular filter paper 2 is fitted onto the outside of the corresponding toothed ring 14 and the rubber toothed ring 15. Then, the lever 114 is turned again and the insert block 111 is slid to the other end of the corresponding slot 112. At this time, the lever 114 is released again, and then the insert rod 17 will be inserted into the corresponding insertion hole. At this time, the other end of the corresponding new annular filter paper 2 will be tightly fitted with the corresponding rubber toothed ring 16.

[0025] In addition, before installing the new annular filter paper 2, the rocker arm 34 can be turned, which can drive the handwheel 33 to rotate, which in turn can drive the rotating rod 31 to rotate, which can further drive the frame brush 32 to rotate, so as to easily clean the impurities attached to the inner wall of the mesh barrel 12, and after cleaning, the cleaned impurities can be discharged.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
