Mobile mining face dust remover

Abstract

The invention relates to a mobile mining face dust remover. The mobile mining face dust remover is characterized by comprising a dust cover body, multiple turning plate type dust discharging hoppers arranged on the upper portion of the dust cover body, turning plate type dust discharging valves arranged between the corresponding turning plate type dust discharging hoppers and the dust cover body, and dust guide passages which are arranged on the upper portions of the corresponding turning plate type dust discharging hoppers and communicated with the corresponding turning plate type dust discharging hoppers and axial flow fans and energy reducing stoppers which are arranged in the dust guide passages; the end, close to the mining face, of each dust guide passage is opened, the other end of the dust guide passage is provided with a filter screen, multiple dust sucking mouths are formed in the side walls and the tops of the dust guide passages in the length direction of the passages, the axial flow fans are fixed at the ends close to the corresponding filter screens, the energy reducing stoppers are each shaped like a plate and are arranged on the two sides inside the corresponding dust guide passages in a staggered mode, and oblique included angles are arranged between the energy reducing stoppers and the side walls of the dust guide passages. According to the mobile mining face dust remover, the dust raising problem in the mining and mine loading and unloading processes is thoroughly solved, the structure is simple, and use is reliable.

Description

technical field [0001] The invention relates to a dust collector used in mining and loading and unloading of power generation, mining, steel, cement, coal, flour, ports and other industries to collect large-scale dust, which can replace the bag dust collector, especially a mobile mining surface dust collector. Background technique [0002] At present, in order to solve the problem of dust on the mining face, water spraying and dust reduction methods are generally used at home and abroad, such as water spraying and dust reduction on the mining face of coal mines, but there are the following problems: the use of water spraying to reduce dust can only reduce a small part of coal dust. Water dust reduction is to let the coal dust absorb water and increase the weight of the coal dust to make it self-falling. However, because there is kerosene on the coal dust, the time for the coal dust to absorb water mist is lagging behind, and the amount of coal dust produced by the excavator ...

Problems solved by technology

[0002] At present, in order to solve the problem of dust on the mining face, water spraying and dust reduction methods are generally used at home and abroad, such as water spraying and dust reduction on the mining face of coal mines, but there are the following problems: the use of water spraying to reduce dust can only reduce a small part of coal dust. Water dust reduction is to let the coal dust absorb water and increase the weight of the coal dust to make it self-falling. However, because there is kerosene on the coal dust, the time for the coal dust to absorb water mist is lagging behind, and the amount of coal dust produced by the excavator is continuous, so in coal mines Dust accumulation will occur on the mining surface

At present, although various mining areas have strengthened labor protection for underground workers, such mining environment will still cause a large number of workers to develop silicosis, which seriously affects the work quality of underground workers and even threatens their lives.

At the same time, the excessively high dust concentration has also brought hidden dangers to production safety. Many mine disasters occur either due to dust explosions causing gas explosions, or gas explosions causing dust explosions

In order to solve the above problems, it is also said that the bag filter can be used instead of water spraying to reduce dust. Although the bag filter can be used underground in theory, the concentration of flour dust in underground mining is too high, which requires a large filter area of ​​the bag filter, and the underground space is limited. In addition, the mining face is mobile. With the progress of the mining face, goafs and subsidence collapse areas are formed in the earliest mining areas. Even if there is space to install the bag filter, the bag filter It is very difficult to move, so the bag filter cannot be used underground
