[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2 As shown, the sedimentation tank for water purification system includes a tank body 1, a water inlet pipe 2 at the upper left position of the tank body 1, a drainage pipe 3 at the lower right position of the tank body 1, a first sewage outlet 4 on the left and right sides of the bottom of the tank body 1, and a screw conveyor 5 connected to the first sewage outlet 4. The screw conveyor 5 is used to discharge sludge and debris. A second sewage outlet 6 is provided at the upper left position of the tank body 1. The second sewage outlet 6 is used to discharge floating debris and oil. A sewage trough 7 connected to the second sewage outlet 6 is provided on the left side of the tank body 1. The sewage trough 7 is used to store, collect and discharge debris and oil. A sewage pipe 8 is installed at the water outlet of the sewage trough 7. The sewage pipe 8 is connected to the screw conveyor 5. A scraper 9 is provided in the middle of the inner cavity of the tank body 1. The bottom of the scraper 9 can scrape off the sludge at the bottom of the inner cavity of the tank body 1, and the top can scrape off floating objects. The scraper 9 is provided with a water trough 10, and threaded rods 11 are symmetrically arranged on the front and back positions above the inner cavity of the pool body 1. The threaded rods 11 are meshed with the scraper 9 for transmission. A motor 12 connected to the threaded rods 11 for transmission is also installed on the right side of the pool body 1.

[0022] Furthermore, the drain trough 7 is tilted, and one end of the drain trough 7 close to the tank body 1 is higher than the other end, so as to facilitate the discharge of floating oil and debris.

[0023] Furthermore, a switch valve 13 is installed on the sewage pipe 8 .

[0024] Furthermore, guide rods 14 are symmetrically arranged at the lower part of the inner cavity of the tank body 1, and the scraper 9 is slidably connected to the guide rods 14.

[0025] Working principle: sewage enters the inner cavity of the tank body 1 through the sewage pipe 3. Floating objects are blocked by the scraper 9 and are concentrated on the left side of the scraper 9. When the motor 12 drives the scraper to move toward the side of the sewage trough 7, the water level on the left side of the scraper 9 rises slightly. At the same time, under the action of the water trough 10, the water level rises not too high. During the movement of the scraper 9, on the one hand, it can push floating debris and oil on the liquid surface into the sewage trough 7, and the floating debris and oil enter the screw conveyor 5 through the sewage trough 7 and the sewage pipe 8. On the other hand, the sludge on the left side of the inner cavity of the tank body 1 is pushed into the first sewage outlet 5 under the action of the scraper 9. When the motor 12 drives the scraper 9 in reverse to move toward the other side, it can push the sludge on the other side of the inner cavity of the tank body 1 into the other sewage outlet 5, and the floating debris, oil and sludge are discharged through the screw conveyor 5.
