Coal dressing separator

Abstract

The invention discloses a coal dressing separator, and relates to the technical field of a centrifuge, comprising a motor, a torque flow pump, a first-stage swirler and a second-stage swirler, wherein the motor is connected with the torque flow pump by a shaft coupler, the head of the torque flow pump is fixedly connected with the first-stage swirler, a housing on the head of the torque flow pump and the first-stage swirler are designed into a whole, and a material outlet of the pump directly enters into the first-stage swirler, so that the massive middle wear-resistant pipes, elbows, valves and the like in the conventional connection mode between the pump and the first-stage swirler can be saved, and the production, manufacture and maintenance cost of the equipment can be greatly reduced; the lift of the pump can be shortened, so that the shaft power of the pump can be greatly reduced, and the energy saving effect is obvious; and the evenly-mixed raw material can directly enter into the first-stage swirler at the same speed due to the device, so that the raw coal dressing effect can be improved. Furthermore, the separator is smaller in volume, and more compact in structure, and a pipeline between the torque flow pump and the first-stage swirler is better in air impermeability and high in safety since the used pipeline is shorter.

Description

Technical field [0001] The invention relates to the technical field of centrifugal devices, in particular to a coal preparation separation device. Background technique [0002] Traditional coal separation equipment includes electric motor, cyclone pump, one-stage cyclone and two-stage cyclone, such as figure 2 As shown, the electric motor is connected with the swirl pump through a coupling to provide power for the swirl pump. The swirl pump is sealed to the raw coal inlet of a section of the cyclone through a long intermediate wear-resistant pipeline, and is carried out in the coal separation device. During the separation process of raw coal and coal gangue, the intermediate wear-resistant pipe needs to withstand greater pressure and friction, the intermediate wear-resistant pipe is easily damaged, and the price of the intermediate wear-resistant pipe is generally very expensive, thereby increasing the manufacturing of the device Costs and maintenance costs. Summary of the inven...

[0002] The traditional coal preparation and separation device includes a motor, a swirl pump, a first-stage cyclone and a second-stage cyclone, such as figure 2 As shown, the motor is connected to the swirl pump through a coupling to provide power for the swirl pump. The swirl pump is sealed and connected to the raw coal inlet of a swirler through a long section of intermediate wear-resistant pipeline. During the separation process of raw coal and coal gangue, the intermediate wear-resistant pipeline needs to bear relatively large pressure and friction force, the intermediate wear-resistant pipeline is easy to be damaged, and the price of the intermediate wear-resistant pipeline is generally very expensive, thereby increasing the manufacturing cost of the device.
