It uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter in water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank;

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. In the utility model, at least one scraper is fixed to the main rotating column along the tangential direction. When the main rotating column rotates, the scraper can be driven to rotate. When the scraper rotates, the sludge deposited inside the bucket portion can be pushed to enter the lower mud port. Since the diameter of the main rotating column of the scraper has a certain angle, the sludge is subjected to not only the tangential force but also the centripetal force, so the sludge can be better pushed into the lower mud port.
[0014] 2. The utility model is provided with an auxiliary power assembly. When the motor is working, it can drive the power-assisting gear to rotate. When the power-assisting gear rotates, it can move on the large gear ring, thereby driving the entire scraper blade to move. The scraper blade can be driven by the auxiliary gear on the one hand and by the main rotating column on the other hand, thereby reducing the stress on the main motor and extending the life of the main motor.

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.
[0020] See also Figure 1 As shown, in the embodiment of the utility model, a water pollution control sedimentation tank comprises a sedimentation tank body 1, a lower mud opening 12 is provided at the lower part of the sedimentation tank body 1, preferably the lower part of the sedimentation tank body 1 is set as a bucket-shaped part 11, and the lower mud opening 12 is arranged at the middle part of the bottom surface of the bucket-shaped part 11, so that the silt sunk in the sedimentation tank body can enter the lower mud opening 12 through the bucket-shaped part 11;
[0021] Combination Figure 1 and Figure 2 As shown, a vertical main rotating column 4 is provided in the middle of the sedimentation tank body 1, and at least one scraper 3 is fixed on the main rotating column 4 along the tangential direction (in this embodiment, the lower surface of the scraper 3 is provided with an inclined portion 32 that matches the bucket-shaped portion 11). When the main rotating column 4 rotates, the scraper 3 can be driven to rotate. When the scraper 3 rotates, the sludge deposited inside the bucket-shaped portion 1 can be pushed to enter the lower mud port 12. Since the scraper 3 and the diameter of the main rotating column 4 have a certain angle, it can better push the sludge into the lower mud port 12. Preferably, a main motor 6 for driving the main rotating column 4 to rotate is installed below the sedimentation tank body 1;

The power-assisting gear 5 is engaged with the large gear ring 2, and can drive the power-assisting gear 5 to rotate when the motor is working. When the power-assisting gear 5 rotates, it can move on the large gear ring 2, thereby driving the entire scraper blade 3 to move, and then the scraper blade 3 can be driven by the auxiliary gear 5 on the one hand, and by the main rotating column 4 on the other hand.
[0023] The working principle and use process of the utility model: when using the device, the main motor 6 can drive the main rotating column 4 to rotate, thereby driving the scraper 3 to rotate. At the same time, the motor can drive the power-assisting gear 5 to rotate when working.
