[0002] The wastewater generated in the asphalt production process is not only turbid and smelly, but also contains a lot of harmful substances, including a large amount of SS and COD, and a large amount of phosphorus-containing sludge. The existing sludge and oil-water separation device consists of a sedimentation tank, which places a certain amount of solid and liquid in the tank. After standing for a period of time, the oil and water are pumped out through a pumping pipe. However, part of the oil and water in the static solid and liquid will accumulate in the sludge, reducing the separation efficiency.

[0021] A circular hole 12 is provided on the left side of the top of the box body 1, and a water pump 8 is fixedly installed on the outer left wall of the box body 1. The input end of the water pump 8 is fixedly connected to one end of an L-shaped tube 9, and the other end of the L-shaped tube 9 is fixedly connected to a bellows 10. A standpipe 11 is fixedly installed at the bottom end of the bellows 10, and the bottom end of the standpipe 11 extends into the box body 1 through the circular hole 12;

[0022] When the oil and water in the sludge in the box 1 are turned out, the height of the sludge will drop, and the riser 11 can be moved downward through the variable length characteristic of the bellows 10 so that its bottom end extends into the oil and water.

[0023] A positioning member 13 is provided in the circular hole 12 .

[0024] Specifically, a mounting hole is provided on the left side wall of the box body 1, and an observation window 14 is fixedly installed on the inner side wall of the mounting hole.

[0026] Specifically, the top and the bottom of the transverse plate 7 are both provided with a tapered surface 15 .

[0027] Due to the arrangement of the conical surface 15, when the transverse plate 7 moves up and down, the top and bottom of the transverse plate 7 can be easily inserted into the sludge.

[0028] Specifically, the positioning member 13 includes a spring 16, and a square groove 18 is provided at the right end of the inner wall of the circular hole 12. The right end of the spring 16 is fixedly mounted on the inner right wall of the square groove 18, and a square plate 17 is fixedly mounted on the left end of the spring 16.

[0034] Working principle: Figure 2 In the process, solid and liquid are injected into the box body 1 through the feed pipe 2. After standing for a period of time, oil and water gather on the top of the sludge. The oil and water on the top of the sludge are pumped out by the water pump 8, and then the horizontal plate 7 is controlled by the hydraulic cylinder 4 to move up and down to turn the sludge, so that the oil and water accumulated in the sludge gather on the top of the sludge. At this time, the height of the sludge will drop, and then the vertical plate 20 is moved to the right to make the square plate 17 separate from the vertical pipe 11, and then the vertical pipe 11 is moved downward to make the bottom end of the vertical pipe 11 inserted into the oil and water.
