Problems solved by technology

The simple pressure type only has simple spraying and dilution functions, and cannot remove dust, so the scope of pollution is large
The simple suction dust collector can remove part of the dust, but it is only due to the short suction distance due to simple suction, which affects the dust collection and dust removal effect; wide-ranging negative impact

Embodiment Construction

[0012] The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

[0013] Implementation example

[0014] As shown in the figure, the present invention includes an upper cylinder (2), a lower cylinder (3) is arranged below the upper cylinder (2), the upper cylinder (2) and the lower cylinder (3) and the roadway (6) of the excavation working face, and the A range of blowing out and suction is formed between the working face ends (7), so the pollution is only in this range, which is very small.

[0015] The working principle of the present invention is as follows:

[0016] The purpose of the present invention is to use the air flow field of the upper and lower chambers to concentrate the dust in the smallest range and collect and remove it. The upper chamber is equipped with a pull-out dust collector (1), and the lower chamber (3) is equipped with a blower blown out by a press-in fan, so that the jet flow in the lower chamber f...

Abstract

The invention discloses a dust isolation and collection method for a fully mechanized excavation face, which comprises an upper drum (2) and a lower drum (3), wherein the lower drum (3) is arranged below the upper drum (2), the upper drum is connected with an upper cavity bell mouth (4), the lower drum is connected with a lower cavity bell mouth (5), a withdrawable dust remover (1) is arranged in the upper drum (2), the upper cavity bell mouth (4) forms a negative pressure zone, a press-in type ventilator (11) is arranged in the lower drum (3), and the lower cavity bell mouth (5) forms a positive pressure zone. Due to the adoption of the structure, the dust isolation and collection method can greatly reduce the scope of pollution in use. Meanwhile, a dust-tight rectangular air curtain is also formed, thereby improving the effectiveness of dust isolation and collection and reducing the chance of suffering from pneumoconiosis of workers.

Description

technical field [0001] The invention relates to a dust isolation and dust collection method, in particular to a dust isolation and dust collection method for fully mechanized excavation working faces in coal mines. Background technique [0002] At present, a simple dust collector is generally used for dust removal in the excavation work of the coal mine fully mechanized excavation face, and the commonly used one is generally a simple pull-out structure, which sucks the dust-containing airflow into the dust collector. The simple pressure type only has simple spraying and dilution functions, and cannot remove dust, so the scope of pollution is large. The simple suction dust collector can remove part of the dust, but it is only due to the short suction distance due to simple suction, which affects the dust collection and dust removal effect; Wide range of negative effects. Contents of the invention [0003] The purpose of the present invention is to provide a dust-separatio...
