Flow guide type tapered sedimentation tank

The utility model relates to a flow guide type tapered sedimentation tank. A ring-shaped clarified liquid overflow weir opening is arranged at the top end of the wall of a tank body, a sludge discharging opening controlled by a valve is arranged at the tapered bottom of the tank body, a liquid inlet pipe fixed by a liquid inlet pipe bracket is stretched in the center of the tank body, and a liquid guide cylinder which covers a liquid outlet is directly arranged on the inner tapered surface of the tank body. A flow guide plate arranged at the outlet position of the liquid inlet pipe can guide suspending liquid which flows out from the liquid outlet and is to be separated to the inner wall of the liquid guide cylinder. A simple and effective flow guide device is arranged in the tank body, and the wavy flow guide plate which works matching with the liquid inlet pipe is arranged at a central liquid inlet pipe orifice, so as to make sure that circulating liquid can be completely clarified in the working process, t
