[0035] 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.

[0036] This utility model provides an anti-clogging filter element, such as Figures 1 to 6 As shown.

[0037] Example 1:

[0038] An anti-clogging filter element includes a housing 1, which is composed of a shell 101 and an end cap 102. A support leg is fixedly installed at the lower end of the shell 101. Multiple air inlet pipes 2 are provided on the side of the shell 101. The end cap 102 is installed at the top of the shell 101 and is provided with an air outlet pipe 3. A valve is provided inside the air outlet pipe 3. The shell 101 and the end cap 102 are connected by bolts.

[0039] A cylindrical filter element body 4 is coaxially mounted inside the outer casing 1. A sealing ring 5 is fixedly connected to the upper end of the filter element body 4. The sealing ring 5 can make the filter element body 4 and the outer casing 1 more stably connected together. A cleaning component is installed inside the filter element body 4.

[0040] The cleaning assembly includes a backflush rod 6, which is driven by a motor 7 to rotate around the axis of the filter element body 4. The backflush rod 6 is connected to an external air pump through a backflush pipe, which includes a main pipe 10 and a branch pipe 11. The main pipe 10 is connected to the backflush rod 6 through the branch pipe 11. The lower end of the main pipe 10 passes through the outer shell 1 and is rotatably sealed with the outer shell 1. The lower end of the main pipe 10 is rotatably sealed with a connecting pipe installed on the outer shell 1. The connecting pipe is connected to an external air pump. A driven gear 12 is fixedly sleeved on one side of the main pipe 10 at the lower end of the outer shell 1. The driven gear 12 meshes with the driving gear 13 on the motor shaft of the motor 7. The motor 7 is installed on the outer shell 1. When the motor 7 is started, its motor shaft can drive the main pipe 10 to rotate through the driving gear 13 and the driven gear 12, thereby driving the backflush rod 6 to rotate around the axis of the filter element body 4. During the rotation of the backflush rod 6, the filter element body 4 can be backflushed.

[0041] Example 2:

[0042] Based on Example 1, in order to improve the cleaning effect on the filter element body 4, a squeezing part is installed between the backwash rod 6 and the filter element body 4. The squeezing part can drive the filter element body 4 to vibrate continuously during the rotation of the backwash rod 6, so that the impurities on the filter element body 4 can be better removed.

[0043] The extrusion section includes an active block 8, with a wedge-shaped surface on the side of the active block 8 facing its rotation direction. Multiple fixed blocks 9 adapted to the active block 8 are distributed circumferentially on the inner wall of the filter body 4. The side of the fixed blocks 9 facing the active block 8 is also a wedge-shaped surface, and the wedge-shaped surface on the fixed blocks 9 is adapted to the wedge-shaped surface on the active block 8.

[0044] When the motor 7 drives the recoil rod 6 to rotate, the active block 8 will continuously squeeze the wedge-shaped surfaces of different fixed blocks 9. When the active block 8 squeezes the fixed block 9, the sealing ring 5 is squeezed and undergoes elastic deformation, and the filter element body 4 will move downward. When the active block 8 passes the current fixed block 9, the filter element body 4 will move downward under the elastic force of the sealing ring 5, so that the filter element body 4 can continuously vibrate axially, so that the impurities on the filter element body 4 can be better removed.

[0045] An annular collection groove 14 is provided on the outer periphery of the filter element body 4 and on the bottom side wall of the outer shell 1, which can collect the impurities that are peeled off from the filter element body 4 and discharge them in a concentrated manner.

[0046] In order to make the filter body 4 vibrate more stably, the number of backflush rods 6 is set to be multiple. At this time, the number of branch pipes 11 is matched with the number of backflush rods 6, and multiple branch pipes 11 are connected to a main pipe 10.

[0047] Example 3:

[0048] The bottom side wall of the collection tank 14 is provided with an outlet, and the inside of the outlet is provided with a sealing plug 15. The bottom side wall of the collection tank 14 is set as an inclined surface, and the position where the collection tank 14 communicates with the outlet is the lowest point of this inclined surface. During the cleaning process of the filter element body 4, the filter element body 4 will cause the outer shell 1 to vibrate continuously during the vibration process, so that the impurities located inside the collection tank 14 can move better towards the outlet and be discharged through the outlet.

[0049] When using:

[0050] 1. Close the valve inside the vent pipe 3 and open the sealing plug 15.

[0051] 2. Start the external air pump to pump gas into the main pipe 10.

[0052] 3. Start the motor 7 to drive the backwash rod 6 to rotate, and perform backwashing on the filter element body 4.

[0053] 4. During backwashing, impurities that fall off the filter element body 4 will enter the collection tank 14 and be discharged through the outlet.

[0054] 5. After cleaning, turn off the external air pump and motor. 7. Open the valve inside the air outlet pipe 3 and insert the sealing plug 15 into the outlet.

[0055] 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.
