Mine coal dressing separating device

The invention discloses a mine coal dressing separating device, and relates to the technical field of centrifugal devices. The mine coal dressing separating device comprises an electric motor, a cyclone pump, a first section hydrocyclone and a second section hydrocyclone. The electric motor is connected with the cyclone pump through a coupler. A pump head of the cyclone pump is fixedly connected with the first section hydrocyclone. A shell on the pump head and the first section hydrocyclone are designed as a whole. A discharging opening of the pump directly enters the first section hydrocyclone. A large number of middle wear-resistant pipelines, elbows, valves and the like used in a traditional connecting way of the pump and the first section hydrocyclone are saved, and the costs of production, manufacturing and maintenance of equipment are reduced greatly; the lift of the pump is shortened, so that the shaft power of the pump is reduced greatly, and the energy-saving effect is obvious; and the mine coal dres
