[0036] The second motor 23 is started to drive the first screw 22 to rotate, and the lifting block 21 is driven to rise through the first screw 22, thereby driving the lifting plate 9 to rise. The rising lifting plate 9 drives the sealing ring 3, the mesh plate 4 and the filter screen 5 to rise through the rotating rod 10, thereby driving the sediment to rise and separate from the liquid.

[0037] Working principle: After the waste liquid and the precipitant are put into the sedimentation barrel 1, the first motor 11 is started to drive the rotating rod 10 to rotate, and the rotating rotating rod 10 drives the scraper 12 and the stirring blade 13 to rotate, so as to stir and mix the waste liquid and the precipitant. After the precipitation is formed, the second motor 23 is started to drive the first screw 22 to rotate, and the lifting block 21 is driven to rise through the first screw 22, thereby driving the lifting plate 9 to rise. The rising lifting plate 9 drives the sealing ring 3, the mesh plate 4 and the filter screen 5 to rise through the rotating rod 10, and drives the precipitation to rise through the mesh plate 4 and the filter screen 5, so that the sealing ring 3, the mesh plate 4 and the filter screen 5 are driven to rise. The sealing ring 3 is located on the upper side of the reflux pipe 16, so that the sediment is separated from the liquid. The water in the sediment passes through the filter screen 5 and the mesh plate 4 and flows into the liquid at the bottom of the sedimentation barrel 1. The water in the sediment can also flow into the liquid at the bottom of the sedimentation barrel 1 through the water trough 14, the water filter hole 15 and the reflux pipe 16 arranged on the side.
