[0032] The box cover plate 2 is provided with a hole in the middle, the connecting rod 3 passes through the hole of the box cover plate 2, the box cover plate 2 and the connecting rod 3 are provided with a shaft seal seat 4 in the middle, the shaft seal seat 4 can prevent the liquid or gas in the box body 1 from leaking to the external environment, and the normal operation of the device is maintained.

[0033] One end of the connecting rod 3 is movably connected with the pressing plate 9, the pressing plate 9 is provided with a hole in the upper center, and the other end of the connecting rod 3 is fixedly connected with the air cylinder 5.

[0034] The upper part of the perforated plate 8 is hinged to the baffle plate 13, and the lower part of the perforated plate 8 is fixedly connected to the baffle plate 13. The plane of the perforated plate 8 forms an angle of 3-5° with the vertical direction. The plane of the perforated plate 8 has perforations with diameters increasing sequentially from bottom to top. The diameter of the perforations at the bottom of the perforated plate 8 is slightly smaller than the diameter of the material being cleaned. When the cleaning machine drains liquid, the internal liquid flows out through the perforations on the perforated plate 8, while the solid material is blocked by the perforations and remains inside the cleaning machine.

[0035] A guide rod 10 is horizontally installed at the upper center of the perforated plate 8. A limiting device is installed at the right end of the guide rod 10. When the pressure plate 9 moves to the left, the upper center opening of the pressure plate 9 passes through the guide rod 10 to guide and make the perforated plate 8 fit with the pressure plate 9. When the pressure plate 9 moves to the right, the limiting device at the right end of the guide rod 10 limits the pressure plate 9.

[0036] A cylinder bracket 6 is installed at the lower end of cylinder 5, and the left end of cylinder bracket 6 is fixedly connected to the housing cover plate 2.

[0037] A backwashing device 11 is installed at the upper end of the housing 1. Liquid or gas can be added into the backwashing device 11 and sprayed out under pressure to achieve backwashing of the blockage material in the opening of the orifice plate 8.

The outlet of the backwashing device 11 is located at the upper end of the middle interlayer between the perforated plate 8 and the baffle plate 14; one end of the connecting rod 3 is connected to the pressure plate 9 through a universal joint 12. Other structures are the same as in Embodiment 1.

[0043] The working principle of this utility model is as follows:

[0044] When the cleaning machine starts to clean the material, the cylinder 5 pushes the connecting rod 3 to move, the connecting rod 3 drives the pressing plate 9 to move close to the hole plate 8, preventing the material or liquid in the cleaning machine from flowing out through the hole plate 8; after the cleaning machine finishes cleaning, the cylinder 5 drives the pressing plate 9 to move, the liquid in the cleaning machine flows out through the hole plate 8, and the solid material in the cleaning machine is accumulated at the bottom of the hole plate 8 under the action of gravity, and the hole diameter at the bottom of the hole plate 8 is small, so the solid material is not easy to flow out with the liquid; after the liquid in the cleaning machine flows out, the liquid outlet valve 7 is closed, the backwashing device 11 sequentially introduces high-pressure gas and high-pressure liquid into the box body 1, and the plane of the hole plate 8 is at a certain angle with the vertical direction, which is helpful for the backwashing process to use the gravity to make the solid particles more easily carried away, and makes all the holes keep unobstructed.

[0045] Each of the embodiments in the specification is described in a related manner, and the same and similar parts between the embodiments can be referred to each other, and each embodiment focuses on the difference from other embodiments.
