[0024] The outer wall of the sedimentation box 1 is installed with a pumping reciprocating pump 2, which includes a guide pipe 201, a pumping pipe 202, a lifting rod 203 and a fixed sleeve 204. The discharge end of the pumping reciprocating pump 2 is connected with the guide pipe 201, and the feed end of the pumping reciprocating pump 2 is connected with the pumping pipe 202. The slots of the guide pipe 201 and the pumping pipe 202 are arranged on both sides of the vertical end of the partition plate 8. The outer wall of the pumping pipe 202 is sleeved with a fixed sleeve 204, and the bottom of the fixed sleeve 204 is installed with a lifting rod 203; the upper end of the outer wall of the sedimentation box 1 is connected to A solvent addition nozzle 3 is provided, and a cleaning discharge nozzle 4 is connected to one side of the lower end of the outer wall of the sedimentation box 1; a feed slot 6 is provided on the top of the sedimentation box 1, and the feed slot 6 and the sliding filter plate 5 are matched with each other in the upper and lower positions; a discharge slot 7 is provided on the outer wall of the end of the sedimentation box 1 away from the partition plate 8; a horizontal sliding structure is formed between the sedimentation box 1 and the sliding filter plate 5, and the sedimentation box 1 and the sliding filter plate 5 are interlocked with each other; a rotation connection is formed between the sedimentation box 1 and the movable baffle 101, and the vertical height of the movable baffle 101 and the partition plate 8 are matched with each other;

[0025] The internal diversion structure is adopted to filter and separate the washing water. The impurities will be transported to the solid tank outside the partition plate 8. The treated washing water will pass through the sliding filter plate 5 and enter the sedimentation tank. After sedimentation, the extraction pipe 202 with adjustable extraction height is used to collect the sediment and the filtered impurities in a centralized manner, which can better avoid the large particle impurities from affecting the sediment extraction effect and improve the separation efficiency.

[0026] Through the horizontal pushing structure, the slag discharge push rod 901 will push the slag discharge push plate 902 to move horizontally. Through the cooperation of the upper protrusion of the slag discharge push plate 902 and the position of the limit block 102, the movable baffle 101 in the solid tank area can be pushed open, causing the movable baffle 101 to rotate counterclockwise, thereby pushing the filtered impurities into the solid tank for centralized collection, realizing the cleaning treatment of the surface of the sliding filter plate 5, and ensuring the smoothness of subsequent filtration;

[0028] Working principle: For this type of washing water filtering and sedimentation device, the washing water to be treated is first injected through the top feed slot 6, so that the washing water passes through the bottom sliding filter plate 5, so that the washing water is subjected to particle filtration and separation. After the filtration is completed, the filtered washing water will accumulate in the bottom space of the sliding filter plate 5, and some auxiliary sedimentation agents will be added through the outer solvent adding nozzle 3, so that the filtered washing water will undergo sedimentation. While the sedimentation operation is in progress, the slag discharge component 9 can be controlled to push the slag discharge push plate 902 on one side to move horizontally through the driving of the slag discharge push rod 901, so as to scrape the surface of the sliding filter plate 5 and push the filtered residue to the end of the movable baffle 101. When pushing, the protrusion on the top of the slag discharge push plate 902 will squeeze the limit block 102 on the movable baffle 101, causing the movable baffle 101 to rotate, so that the filtered residue is pushed and falls into the space separated by the inner wall of the sedimentation box 1 and the outer wall of the partition plate 8;

[0029] When the sedimentation operation is completed, the pumping reciprocating pump 2 on one side is controlled to start, and the sediment after sedimentation is extracted, so that the sediment is transported from the end of the pumping pipe 202 to the end of the guide pipe 201, so as to complete the centralized collection of the filtered residue and the sediment. After that, the remaining filtered water can be transported and processed through the cleaning discharge pipe 4, and the solid impurities can be centrally processed through the discharge slot 7;

[0030] The sliding filter plate 5 at the top can also be maintained by sliding, and filter plates with different filter apertures can be replaced according to different needs to better meet filtering needs.
