Coarse coal slime sorting machine

Abstract

The invention belongs to the field of coal mine mechanical equipment and particularly relates to a coarse coal slime sorting machine, which comprises an electric actuating mechanism. The electric actuating mechanism is sequentially connected with an adjustable feeding device and a cyclone interference device of a pipe structure. The cyclone interference device is arranged in a water tank and comprises a plurality of arc-shaped plates. A movable casing can be in close contact with the arc-shaped pates on the cyclone interference device during field installation to guarantee materials to fully flow along the direction of the arc-shaped plates. The cyclone interference device in the coarse coal slime sorting machine enables the materials to forcibly form rotational flow under the effect of the arc-shaped plates on the cyclone interference device to enable the materials to be evenly scattered, so that the sorting effect can be improved by approximate 10 percent. The coarse coal slime sorting machine can still reach a better scattering effect under the situation that the materials flow naturally, the feeding pressure is not required to be increased and the construction cost and the production process cost are reduced.

Description

(1) Technical field [0001] The invention belongs to the field of mechanical equipment for coal mines, and in particular relates to a coarse coal slime separator. (2) Background technology [0002] Coarse slime separator is a kind of floating-sink type separation under the influence of turbulent flow interference from the water tank at the bottom of the cylinder, which sprays out a rising water flow with a certain pressure, which forms a turbulent flow in the cylinder with the material flowing into the feeding device. The material is injected into the barrel from the inlet of the feeding device, and forms a swirling flow under the action of the feeding well, and at the same time, the rising water flows through the turbulence valve hole of the turbulence plate of the pressure water tank and is evenly sprayed into the barrel at a certain pressure and flow rate. In the body, the material forms a bed of suspended particles with different densities under the action of the jet ...

AI Technical Summary

Problems solved by technology

If the feeding pressure is insufficient, the material cannot be formed into a swirling flow to disperse evenly, resulting in the phenomenon of partial accumulation of the material, which affects the separation effect.

And increasing the feeding pressure will inevitably increase the process cost
