Thickener feeding well diluting device

The invention provides a thickener feeding well diluting device which comprises a feeding groove and a thickener upper clear liquid area which are communicated through the diluting device, a feeding port is formed in one end of the feeding groove, the diluting device comprises a shell, a turbine and a propeller, the turbine and the propeller are fixedly connected, the turbine is arranged at the position, close to the feeding port, in the feeding groove, and the propeller is arranged in the feeding groove. The propeller is arranged in a clear liquid area on the thickener. The turbine is fully utilized to capture energy from flowing ore pulp and rotate, then the propeller is driven to rotate, the propeller pumps clear liquid on the thickener into the feeding groove to be mixed with the ore pulp for dilution, the technology that an existing active dilution device needs to be driven by external energy is avoided, in addition, the rotating speed of the turbine is in positive correlation with the incoming material
