[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a sedimentation device for treating fluorine-containing wastewater includes a sedimentation tank 1, a support seat 2 is provided at the bottom of the sedimentation tank 1, a cleaning plate 6 is provided in the sedimentation tank 1, two guide rods 7 are slidably inserted on the cleaning plate 6, both ends of the guide rod 7 are fixedly connected to the two inner walls of the sedimentation tank 1, an adjusting screw 8 is provided between the two guide rods 7, the adjusting screw 8 passes through the cleaning plate 6 and is connected to the cleaning plate 6 by threaded fitting, both ends of the adjusting screw 8 are rotatably connected to the two inner walls of the sedimentation tank 1, a motor 9 is fixedly connected to the outer wall of the sedimentation tank 1, and the output shaft of the motor 9 is fixedly connected to the center of the shaft end of the adjusting screw 8.

[0017] Among them, a plurality of sedimentation tanks 11 are opened at the bottom of the sedimentation tank 1, and the plurality of sedimentation tanks 11 are distributed at equal intervals. The cross-section of the sedimentation tank 11 is an isosceles trapezoidal structure and the opening size decreases from top to bottom. A discharge port 10 extending to the bottom of the sedimentation tank 1 is opened at the bottom of the sedimentation tank 1. A baffle plate 4 is arranged in the discharge port 10. One end of the baffle plate 4 slides through the side wall of the sedimentation tank 1 and extends to the outside of the sedimentation tank 1. A fixed vertical plate 5 is fixedly connected to the upper side of the protruding end of the baffle plate 4.

[0018] When in use, the suspended matter and solid particles settled in the wastewater can be collected through the settling tank 11, so that the suspended matter and solid particles slide along the inclined surface of the settling tank 11 to the discharge port 10, which is convenient for the subsequent cleaning of the settled suspended matter and solid particles. The opening and closing of the discharge port 10 can be controlled by the set baffle plate 4, and the set fixed vertical plate 5 can facilitate the staff to hold the protruding end of the baffle plate 4, thereby facilitating the staff to move the baffle plate 4.
