The outer periphery of the vertical rod 13 is in sliding contact with the reserved hole on the moving plate 17. The moving plate 17 is elastically connected to the baffle 16 through a first spring 18. The first spring 18 is sleeved on the vertical rod 13, one end of the first spring 18 is fixedly connected to the bottom of the baffle 16, and the other end of the first spring 18 is fixedly connected to the top of the moving plate 17. The moving plate 17 is provided with a plurality of second through holes 19 evenly distributed in a circular pattern. In this embodiment, the first through holes 12 and the second through holes 19 are each provided with four, and the first through holes 12 and the second through holes 19 are staggered. The movable plate 17 can fit with one side of the circular plate 11 and seal the first through hole 12 and the second through hole 19. The cavity between the piston plate 14 and the circular plate 11 is filled with a plurality of small balls, which are not shown in the figure. A vertical cylinder 20 with an opening at the top is provided in the cleaning chamber 8. The vertical cylinder 20 is installed on the vertical pipe 10. The vertical cylinder 20 is coaxially arranged with the vertical pipe 10. A plurality of second strip filter holes 21 evenly distributed in a circumferential manner are provided on the vertical cylinder 20. An electric push rod 22 is fixedly installed on the tank body 1. The electric push rod 22 is fixedly connected to the baffle 16. The fixed end of the electric push rod 22 is fixedly installed in the reserved hole at the top of the tank body 1. The movable end of the electric push rod 22 is fixedly connected to the baffle 16. The present invention has a simple structure and an ingenious design. The filter holes are formed by the gaps between the squeezed small balls, and the sewage can be filtered. When the filtered material needs to be cleaned, the small balls are no longer squeezed, so that the small balls are sparsely distributed and immersed in water, thereby achieving the effect of flushing and cleaning, facilitating the treatment of the filtered material, meeting actual needs, and being suitable for promotion.When using the present invention, the electric push rod 22 is shortened to put the small ball in a squeezed state. At this time, the bottom surface of the piston plate 14 is lower than the lower end of the first strip filter hole 15, and the top surface of the piston plate 14 is higher than the lower end of the first strip filter hole 15. Then, sewage is passed from the water inlet 2 into the water inlet chamber 6, and the water enters the upper part of the vertical pipe 10 and passes through the second through hole 19 and the first through hole 12 in sequence. Enter between the circular plate 11 and the piston plate 14, at this time, the small ball is squeezed by the piston plate 14 and the circular plate 11, and the gap between the small balls is small, thereby forming a filter hole. , the sewage is filtered, and the filtered water enters the filter chamber 7 through the first strip filter hole 15, and then is discharged from the water outlet 3. When the filtered material needs to be cleaned, the cleaning liquid is introduced into the cleaning chamber 8 through the water inlet pipe 9, and then the electric push rod 22 is controlled to extend, and the electric push rod 22 drives the baffle 16, the first spring 18, the moving plate 17, the vertical rod 13, and the piston plate 14 to move downward until the moving plate 17 contacts the circular plate 11. During this process, the top surface of the piston plate 14 is always higher than the lower end of the first strip filter hole 15 to ensure that the inlet The sewage entering between the small balls can be completely filtered and flow into the filter chamber 7 through the first strip filter hole 15. When the movable plate 17 contacts the circular plate 11, the first through hole 12 and the second through hole 19 are closed, and the sewage cannot enter the gap between the small balls. The first spring 18 is compressed. As the electric push rod 22 extends, the piston plate 14 moves downward continuously. When the top surface of the piston plate 14 is flush with the lower end of the first strip filter hole 15, the sewage filtered between the small balls has completely flowed into the filter chamber 7. At the same time, the first spring 18 is continuously compressed, and the movable plate 1 The tighter 7 is pressed, the better the sealing effect. After the piston plate 14 moves, the balls are no longer squeezed, and the balls are sparsely distributed. The electric push rod 22 extends, so that the piston plate 14 drives the balls to move into the cleaning chamber 8 and immerse them below the cleaning liquid level 100, so that the water cleans the balls. After cleaning, the filtered matter is discharged from the outside of the vertical cylinder 20 through the second strip filter hole 21. After cleaning, the electric push rod 22 is shortened to drive the piston plate 14 to reset, and the balls can be squeezed again. When the cleaning waste liquid needs to be cleaned, the valve on the sewage pipe 4 can be opened.

[0018] Specifically, if Figure 1 , Figure 2 As shown, the tank body 1 described in this embodiment is fixedly mounted on the base 24 through a plurality of supporting legs 23. The tank body 1 is supported by the supporting legs 23 and the base 24 for convenient use.

[0019] Specifically, Figure 1As shown, a coaxial spring rod 30 is fixedly installed in the vertical cylinder 20 described in this embodiment. The spring rod 30 is a spring telescopic rod whose movable end can only be telescopically changed relative to the fixed end. A spur gear 31 is fixedly installed on one end of the spring rod 30, and the other end of the spring rod 30 extends to the outside of the tank body 1 and is rotatably connected to the reserved hole on the tank body 1. The movable end of the spring rod 30 is fixedly connected to the spur gear 31, the upper end of the fixed end of the spring rod 30 is fixedly connected to the reserved hole on the vertical cylinder 20, and the lower end is rotatably connected to the inner wall of the reserved hole at the bottom of the tank body 1 through a sealed bearing, a tooth groove 32 that can mesh with the spur gear 31 is provided on the piston plate 14, and a coaxial bevel gear ring 33 is fixedly installed on the spring rod 30. A bevel gear 34 is meshed on one side, and the bevel gear 34 is fixedly installed and connected to the output shaft of the motor 35. The output shaft of the motor 35 is coaxially arranged with the bevel gear 34. The motor 35 is fixedly installed on the tank body 1. The vertical cylinder 20 is rotatably connected to the vertical pipe 10 through a sealed bearing. The bottom end of the vertical pipe 10 is fixedly connected to the inner ring of the sealed bearing, and the outer ring of the sealed bearing is fixedly connected to the upper end of the vertical cylinder 20. The piston plate 14 is rotatably installed on the vertical rod 13 through a sealed bearing. A groove is provided on the piston plate 14. The outer periphery of the vertical rod 13 is fixedly connected to the inner ring of the sealed bearing, and the outer ring of the sealed bearing is fixedly connected to the inner wall of the groove. The top of the sealed bearing is flush with the top of the piston plate 14 to avoid affecting the gap between the balls. The extension of the electric push rod 22 drives the vertical rod 13 and the piston plate 14 to move downward, so that the tooth groove 32 is meshed with the spur gear 31, and the electric push rod 22 continues to extend, so that the ball is located in the water, and the spring rod 30 is compressed. At this time, the motor 35 is energized, and the rotation of the motor 35 drives the bevel gear 34 to rotate, thereby driving the bevel gear ring 33, the spring rod 30, the vertical cylinder 20, and the piston plate 14 to rotate together, thereby driving the small ball to rotate, so that the small ball moves in the water, increasing the cleaning effect of the water flow on the small ball, and facilitating use; when the electric push rod 22 is shortened, the piston plate 14 drives the small ball to emerge from the water, and the spur gear 31 is still meshed with the tooth groove 32. At this time, the spring rod 30 drives the vertical cylinder 20 and the small ball to rotate, and the centrifugal action generated by the rotation can throw the water and filtered matter on the small ball out of the second strip filter hole 21, further improving the cleaning effect.

[0020] Further, such as Figure 1 As shown, the spring rod 30 and the spur gear 31 in this embodiment are elastically connected via a second spring 40, the second spring 40 is sleeved on the movable end of the spring rod 30, one end of the second spring 40 is fixedly connected to the fixed end of the spring rod 30, and the other end of the second spring 40 is fixedly connected to the spur gear 31. The second spring 40 increases the stability of the spring rod 30 when it is extended and retracted, and is conducive to the resetting of the spring rod 30, so that it is easy to use.

[0021] Furthermore, Figure 1As shown, a plurality of sealing plugs 50 are fixedly installed on the movable plate 17 corresponding to the first through holes 12 in this embodiment, and the sealing plugs 50 can seal the corresponding first through holes 12. When there are large particles of filtered matter between the circular plate 11 and the movable plate 17, so that the movable plate 17 cannot fit with the circular plate 11, the sealing plugs 50 will still be inserted into the first through holes 12, thereby sealing the first through holes 12 to prevent the entry of sewage.

[0022] Furthermore, Figure 1 , Figure 2 As shown, the bottom of the tank body 1 of this embodiment is provided with a sewage outlet 60, and a sealing cover 61 is provided in the sewage outlet 60. The outer periphery of the sealing cover 61 is connected to the inner wall of the sewage outlet 60 through a threaded connection. By removing the sealing cover 61, it is more convenient to discharge the sludge from the sewage outlet 60. After cleaning, the sealing cover 61 can be screwed on again.

[0023] Furthermore, Figure 1 As shown, in this embodiment, the first strip filter hole 15 is a short filter hole, and the bottom surface of the piston plate 14 is not higher than the bottom of the first strip filter hole 15. The first strip filter hole 15 is a short filter hole to prevent the first strip filter hole 15 from being too long when the ball is pressed, so that the sewage flows out directly from the upper part of the first strip filter hole 15; the bottom surface of the piston plate 14 is not higher than the bottom of the first strip filter hole 15 to ensure that the sewage does not flow into the vertical cylinder 20 during filtration.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
