Forced dilution system of thickener

The invention provides a forced dilution system of a thickener. The forced dilution system comprises the thickener, water pumping equipment and an electric hoist arranged above the water pumping equipment; an electric control signal of the electric hoist is connected to an automatic control system of a filling station; and a video monitoring system used for monitoring the height of the electric hoist is arranged on the top of the thickener, the automatic control system remotely controls the electric hoist according to video information collected by the video monitoring system so as to control the water pumping equipment, and then the water pumping equipment is controlled to pump out the clear water in the thickener so as to forcibly dilute the tailing mortar of a dressing plant. According to the forced dilution system of the thickener provided by the invention, the settling and concentrating efficiency of tailings is greatly improved; and the device has the advantages of simple and reasonable structure, conve
