[0020] Step 3: After cleaning, the electromagnet is de-energized, the stretched first spring moves the outer cover seat upward, the stretched second spring moves the inner cover seat downward, the first motor works to realize the rotation of the hollow shaft and the first support plate, and the second support plate is rotated synchronously through the polygonal shaft, thereby moving the outer cover seat and the inner cover seat to different positions of the filter element for cleaning and impurity removal.
[0021] The beneficial effects of this invention are: the outer cover and the inner cover are attracted by electromagnets and permanent magnets to form a closed cleaning space, which, combined with the adjustable spray seat, can clean the filter element. High-pressure filtrate is delivered to the spray seat through the hollow shaft to backwash the filter element pores. With the help of the drain pipe to remove impurities in real time, maintenance can be carried out without stopping the machine.
[0022] The multi-axis drive drives the outer and inner covers to rotate synchronously via the first motor, thereby moving the outer and inner covers to different positions on the filter element. The spray nozzle moves axially along the first slide rail inside the outer cover, enabling the cleaning of the filter element at any position in all directions. Attached Figure Description

Combined with the axial locking of the pressure frame 9 and the pressure ring 7, it ensures no leakage under high pressure conditions.
[0036] A blockage-clearing mechanism 10 is installed inside the cylinder 1. The blockage-clearing mechanism 10 includes a first support plate 14 and a second support plate 17 that rotate synchronously. The first support plate 14 is located outside the filter element 6, and the second support plate 17 is located inside the filter element 6. The blockage-clearing mechanism 10 also includes a transmission box 11 installed outside the cylinder 1. A first motor 12 and a hollow shaft 13 are installed on the transmission box 11. Rotary teeth are installed on the output end of the first motor 12 and on the hollow shaft 13, and the two rotating teeth mesh with each other. The end of the hollow shaft 13 is located inside the cylinder 1 and is connected to the first support plate. The filter element 6 is connected to the first support plate 14, which has a shaft hole 18. A bearing 15 is provided at the end of the filter element 6. A polygonal shaft 16 is installed through the bearing 15 and is connected to the shaft hole 18. The polygonal shaft 16 is connected to the second support plate 17. During the assembly and disassembly of the filter element 6, the polygonal shaft 16 and the first support plate 14 are separated. A first rotating ring 31 is installed at the end of the top plate 19 and is rotatably connected to the fixed flange 3. A second rotating ring 32 is installed at the end of the bottom plate 23 and rotates with the filter element 6. The first support plate 14 is equipped with a top plate 19.

The first movable block 21 is connected to the outer cover seat 22, and the bottom curvature of the outer cover seat 22 is the same as the curvature of the outer wall of the filter element 6. A slide seat 34 is slidably installed inside the outer cover seat 22, and a spray seat 35 is installed on the slide seat 34. A bottom plate 23 is equipped with a second supporting plate 17. A second adjusting seat 24 is symmetrically arranged on the bottom plate 23. A first movable block 21 is elastically installed inside the second adjusting seat 24. Two adjusting blocks 25 are connected to the inner cover seat 26, and the top side curvature of the inner cover seat 26 is the same as the inner wall curvature of the filter element 6. A first spring 27 is installed in the first adjusting seat 20 and is connected to the first movable block 21.

An electromagnet 28 is embedded in the bottom side of the outer cover seat 22, and a permanent magnet 30 is embedded in the top side of the inner cover seat 26. Sealing gaskets are provided on the bottom side of the outer cover seat 22 and the top side of the inner cover seat 26.
[0037] The first motor 12 drives the hollow shaft 13 to rotate through meshing gears, which in turn drives the first support plate 14 to rotate synchronously. The polygonal shaft 16 is not fixedly connected to the first support plate 14 through the shaft hole 18, and transmits the rotational motion to the second support plate 17 to realize the synchronous cleaning action of the inner and outer sides of the filter element 6. When the electromagnet 28 is energized, it attracts the permanent magnet 30. The outer cover 22 and the inner cover 26 clamp the filter element 6 to form a closed chamber. The spring is compressed to ensure that the sealing gasket fits tightly. When the electromagnet 28 is de-energized, the spring rebounds, causing the unclogging mechanism 10 to disengage from the filter element 6. The first motor 12 drives the first support plate 14 and the second support plate 17 to rotate, moving the unclogging mechanism 10 to the next filter element 6 segment.
[0038] The inner cover 26 has a first slide rail 33 inside, which is slidably mounted to the slide block 34. A second slide rail 36 is provided inside the inner cover 26, and several sliders 37 are slidably mounted on the second slide rail 36. Connecting pipes 38 connect adjacent sliders 37 and between sliders 37 and the slide block 34. A fixing pipe 39 is installed on the top plate 19, and the fixing pipe 39 is connected to the hollow shaft 13 and the connecting pipe 38. Rope pulleys 41 are installed inside both ends of the inner cover 26, and two rope pulleys... The wheels 41 are driven by a transmission rope 42, which drives the slide 34 to move. One of the wheels 41 is driven by a second motor 40. The second motor 40 drives the wheel 41 to rotate, and the transmission rope 42 drives the slide 34 to move along the first slide rail 33 to adjust the position of the spray seat 35. When the slide 34 moves, the connecting pipe 38 pulls the slider 37 to move along the second slide rail 36, realizing the connection between the hollow shaft 13, the fixed pipe 39 and the connecting pipe 38.
[0039] A wire is installed inside the hollow shaft 13, and the wire is electrically connected to the power supply, the electromagnet 28 and the second motor 40 respectively.
[0040] The inner cover 26 is connected to a drain pipe 43, and a first connector 44 is installed at the end of the drain pipe 43. A second connector 45 connected to the first connector 44 is installed on the cylinder cover 2, and the second connector 45 is connected to the waste pipe 46 to achieve a plug-in connection. When disassembling the filter element 6, the first connector 44 and the second connector 45 are separated.
[0041] Working principle: The filter element 6 is installed inside the cylinder 1. The pressure ring 7 is acted upon by the pressure frame 9, and the filter element 6 is then installed on the movable flange 4. The medium inlet valve is opened, and the medium enters the cylinder 1. The exhaust port is slowly opened to expel air until the medium flows out steadily. The exhaust port is then closed. The medium is filtered by the filter element 6 and discharged from the discharge pipe. The drain port is opened periodically to discharge impurities. The filter element 6 is cleaned by the unclogging mechanism 10. The electromagnet 28 is energized and attracted to the permanent magnet 30. At this time, the outer cover 22 covers the outside of the filter element 6, and the inner cover 26 covers the inside of the filter element 6, forming an unclogging space between the outer cover 22 and the inner cover 26. The medium in the unclogging space is discharged through the drain pipe 43 and the impurity discharge pipe 46 by the liquid pump. At the same time, the second motor 40 drives the rope wheel 41 to rotate, and the slide 34 moves along the first slide rail 33 through the transmission rope 42, thus cleaning the position of the spray seat 35. Adjustment is performed, and as the slide block 34 moves, the connecting pipe 38 pulls the slider 37 to move along the second slide rail 36. The pressurized pump sprays the filtered medium through the hollow shaft 13, the fixed pipe 39, and the connecting pipe 38, and sprays it out from the spray seat 35 to clean the filter element 6. The cleaned impurities and medium are discharged again through the drain pipe 43 and the waste pipe 46. After cleaning, the electromagnet 28 is de-energized, the stretched first spring 27 drives the outer cover seat 22 to move upward, and the stretched second spring 29 drives the inner cover seat 26 to move downward. The first motor 12 works to realize the rotation of the hollow shaft 13 and the first support plate 14. The hollow shaft 13 rotates in a reciprocating motion, that is, the cleaning process rotates clockwise once and then counterclockwise once. The second support plate 17 is rotated synchronously through the polygonal shaft 16, thereby moving the outer cover seat 22 and the inner cover seat 26 to different positions of the filter element 6 for cleaning and waste removal.
[0042] The outer cover 22 and the inner cover 26 are attracted by the electromagnet 28 and the permanent magnet 30 to form a closed cleaning space. Combined with the adjustable spray seat 35, the filter element 6 is cleaned. The high-pressure filter liquid is delivered to the spray seat 35 through the hollow shaft 13 to backwash the pores of the filter element 6. With the help of the drain pipe 43, impurities are discharged in real time, so that maintenance can be carried out without stopping the machine.
[0043] The polygonal shaft 16 drives the outer cover 22 and the inner cover 26 to rotate synchronously through the first motor 12, thereby moving the outer cover 22 and the inner cover 26 to different positions of the filter element 6. The spray seat 35 moves axially along the first slide rail 33 inside the outer cover 22, realizing the cleaning work of the filter element 6 at any position in all directions.
[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
