A kind of interference bed sorting machine

Abstract

The invention relates to the technical field of coal mine sorting equipment, and discloses a disturbing bed sorting machine, comprising a sorting machine, an overflow collecting tank, a feeding well, a disturbing plate, a discharging valve, a feeding channel, a water inlet channel, an overflow Orifices, actuators, connecting lines, density detectors, density detectors, supporting legs, water bearings, hollow shafts, impellers, rotary screens, caps and supporting devices, and the overflow collection tank is fixedly installed on the top of the sorting machine outside. Compared with the prior art, through the arrangement of the interference plate and the chute at the bottom of the sorter, when the water from the water inlet channel enters the sorter, an upward rotating water flow is generated, and when it meets the coarse coal slime, it can Carry it and rotate it to increase the hovering time of the coarse slime, improve the separation effect of the concentrate, and the tailings can be better concentrated in the middle, thereby reducing the discharge time of the tailings and reducing the interference bed in the separator Unstable time, improve the separation efficiency of coarse slime.

Description

technical field [0001] The invention relates to the technical field of coal mine separation equipment, in particular to an interference bed separation machine. Background technique [0002] Interference bed separator is a coarse slime separation equipment that uses the principle of interference settlement to achieve material separation. It uses the interference bed with a certain density formed by the rising water flow at the bottom of the tank and the descending material to interfere with the settlement, so as to realize the separation of coarse particle materials according to density. , as attached figure 1 As shown, the coarse coal slime is added to the separator from the feeding channel, and at the same time, a water flow with a certain pressure is introduced from the water inlet channel. The rising water flow meets the coarse coal slime in the middle of the separator, and interferes with settlement. An interfering bed with a certain density is formed. When the system r...

Problems solved by technology

[0003] After the coarse coal slime enters the separator from the feed port, it reaches the simplified body through the feed well. During the descent process, the lateral distribution of the coarse slime is uneven, so that when the disturbed bed reaches a stable state, the bed thickness varies. The bed density distribution is not uniform and the bed stability is poor, resulting in a large deviation between the actual separation density and the set separation density, which in turn leads to large fluctuations in the ash content of the separator concentrate, and at the same time causes the materials at the bottom to accumulate on one side, resulting in discharge Valve discharge is not normal, often requires manual discharge and parking, and the detection data of the density detector is inaccurate, making the discharge valve open for too long, resulting in a part of the concentrate flowing out, resulting in losses
