Mine dust removing device

Abstract

The invention discloses a mine dust removing device which is suitable for installing at various tunnels, convenient for cleaning a filter screen and carrying, and good in sealing performance. The minedust removing device comprises a box body and the filter screen positioned inside the box body, wherein the box body consists of a front box body and a rear box body which are matched with each otherin a movable way; the end of the front box body is provided with a filter screen frame, the filter screen is arranged inside the filter screen frame, and the bottom of the filter screen frame is provided with a water draining hole; and water sprayers are arranged at the front and the rear of the filter screen, and the vertex angles of the front box body and the rear box body are in circular arc shapes. By adopting the structure that the front and the rear box bodies are matched with each other in a movable way, the filter screen can be very conveniently disassembled and cleaned; meanwhile, asthe water sprayers are arranged at the front and the rear of the filter screen, the times for cleaning the filter screen can be reduced; and the vertex angles of the front box body and the rear box body are in circular arc shapes, so that the problem of extrusion and occupation between the vertex angles and a vent pipe of the tunnel and the like can be solved. Furthermore, the device is applicable to various tunnels.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device used in underground coal mines. Background technique [0002] At present, the dust-reducing facilities of the tunneling working face of large and medium-sized coal mines are mainly completed by the internal and external spraying device of the cutting head of the roadheader, but the dust removal effect of the spraying device is not ideal, and a large amount of coal dust still pollutes the entire working face The nozzles of spraying devices are often blocked by coal dust. In this regard, many coal mines now use special dust removal equipment on the underground excavation face to further improve the working environment, protect the health of workers, and achieve the purpose of safe and efficient production. The dust removal equipment imported from abroad by individual large coal mines costs more than RMB 1.6 million. However, the KTCS-500LB mining ventilation and wet ...

AI Technical Summary

Problems solved by technology

The KTCS-500LB mining ventilation wet frequency conversion dust removal system independently developed and produced by domestic manufacturers on the basis of introducing foreign technology also costs more than 1.2 million yuan

Such a high equipment cost is unacceptable to most coal mines

In addition, there are some defects in the above two kinds of dust collectors: the top of their box is at right angles

Since the underground ventilation pipes and some electric wires are installed at the two top corners of the underground roadway according to the technical requirements, when using the dust removal equipment, the top corners are likely to occupy space with the underground ventilation pipes, which may lead to dust removal in severe cases. The equipment cannot be used normally in the roadway, and the section layout of the coal mine roadway must be changed to meet the installation needs of the dust removal equipment, which will increase the workload of the workers to change the section layout; their box body is a whole, and the heavy box body must require several workers Lifting at the same time can be installed; the filter inside the box needs to be cleaned regularly, because there is no special cleaning device for the filter in the box, the filter must be taken out before cleaning, which increases the labor intensity of the workers; the maintenance door is set in the box The cover is opened on both sides or on the top, and the seal is solved by simply sticking a seal. When the box shell or door panel is slightly bumped and deformed, the seal is often deformed or destroyed, resulting in dust leakage. Reduced dust collection efficiency
