Description

Dust exhausting device for dry dust remover

Technical Field

The utility model belongs to the technical field of mine dry dust removal equipment, and particularly relates to a dust exhaust device for a dry dust remover.

Background

The dust removing equipment is more than indispensible equipment in the mine beneficiation process, and the working principle is as follows: the dust-containing gas enters the filtering chamber from the lower open flange, coarser particles directly fall into the surface of the bag, and the clean gas is purified to the clean gas chamber through the bag opening and is discharged into the atmosphere by the fan. The coarser particles of the bag table are collected in a dust collecting chamber and enter one or two screw conveyor return belts through a discharge valve. However, the discharging mode is easy to bet on the pipeline, and when dust suddenly increases, the screw conveyor is in overload operation, so that the motor is burnt out. The dust can also cause secondary dust emission when falling into the belt. In addition, the mine crushing process flow needs three-section crushing and one-section screening production lines, and a plurality of devices are required to be distributed to ensure that the workshop environment reaches the standard. The scattered arrangement of a plurality of dust collectors is difficult to convey dust collected by the dust collectors, and the currently adopted dry conveying method has the defects of short conveying distance, rapid equipment abrasion, multiple accident points, low operation rate, incapability of continuous production and the like. Therefore, there is a need for a discharge device for a dry dust collector that utilizes a water dust discharge system to achieve safe and effective dust discharge.
