Dust removal device for mine

Abstract

The invention discloses a dust removal device for a mine. The dust removal device comprises a foam pipe, a dust removal box, a driving wheel, a water outlet, a water pump, a connecting pipe, a water tank, a spray nozzle, a conveying belt, a driven wheel, an air pipe, a draught fan, a metal filtering net, a foam generator, a water saving tank, a first motor, an air sucking hood, a cyclone shaft, acyclone dust removal chamber, a dust removal port, a collecting box, filtering holes, a second motor, a scraping plate, a soil receiving box and a soil outlet. The dust removal device has the beneficial effects that through the rotating dust removal chamber, large particle dust is collected, then foam is generated through the foam generator, and thus under the effect of foam bodies, the dust is gathered into large particles from small particles and finally settles to form soil with broken foam dropping liquid together; and through the conveying belt, the wet soil is conveyed into the soil receiving box, the soil is effectively prevented from adhering to the inner wall of the dust removal box, the filtering holes are formed in the surface of the conveying belt so that water in the soil canbe filtered to be recovered into the water saving tank, and water resource waste can be effectively avoided.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device for mines, belonging to the technical field of mining equipment. Background technique [0002] Mine dust is mainly composed of ore particles and other powders, and is divided into dry dust and wet dust in state. During mining and subsequent processing and production, dust generation is mainly concentrated in the drilling and blasting process, crushing, screening and belt transmission, transportation, and reloading processes. A complete mine processing production line needs to go through processes such as crushing, screening, grinding, transportation, and aggregates. Each process, accompanied by the fragmentation and movement of ore, will gradually separate fine particles, resulting in more and more Much dust. [0003] There are many types of dust with different properties. Generally speaking, the smaller the particle size of the dust, the less likely it is to sett...

AI Technical Summary

Problems solved by technology

Generally speaking, the smaller the particle size of the dust, the less likely it is to settle in the air, and it is difficult to capture it. With the flow of air, it will cause long-term and large-scale pollution, and it is easy to be inhaled into the deep part of the respiratory tract with the air, and the harm to the human body is also greater.

In addition, dust will also lead to the reduction of product quality and machine working accuracy, which will affect production and cause economic losses. For some combustible mine dust, there may even be explosive hazards.

[0004] Since most of the existing dust removal devices use water curtain dust removal devices, not only the dust removal efficiency is low, but there is still a large amount of dust in the gas after the water curtain dust removal, and continuous spraying is required, resulting in a lot of energy waste
