Problems solved by technology

However, the dust removal effect of traditional dust removal methods is poor. For example, spraying water not only has a weak ability to capture respirable dust, consumes a lot of water resources, but also causes secondary pollution to the working environment; foam dust removal agents are more expensive, and later investment is larger , and the foam will obstruct the driver's sight while covering the dust source, affecting the driver's work; ventilation and dust removal can only allow the dust to diffuse to the back of the roadway with the wind direction, and cannot essentially eliminate the dust source
At present, as people pay more attention to their own health, dry filter dust collectors are widely recognized for their high-efficiency dust removal advantages. Large size makes it difficult for dry filter dust collectors to be conveniently used

Example Embodiment

[0018] The present invention will be further described in detail below in conjunction with the drawings.

[0019] Such as figure 1 As shown, a tunneling surface dry dust removal system with a follow-up air drum bracket includes a tunneling machine 1, a transfer machine 2, a moving frame 3, a belt conveyor 4, a dry filter dust collector 5, an exhaust fan 6, a suction The dust cover 7 and the negative pressure air cylinder 8 are fixedly connected to the transfer machine 2 at the tail of the roadheader 1; the transfer machine 2 is slidably installed above the tail of the belt conveyor 4. The tail is installed on the movable frame 3, the dry filter dust collector 5 and the draw-out fan 6 are installed on the movable frame 3 through the bracket, and the draw-out fan 6 is connected to the dry filter dust collector 5 and the negative pressure air duct 8 in turn. And vacuum hood 7,

[0020] The dust removal system further includes a support bracket 9, a suspension slide 10, and a suspensi...

Abstract

A heading face dry dust removing system with a follow-up air duct support comprises a heading machine (1), a reversed loader (2), a movable rack (3), a belt conveyor (4), a dry filter dust remover (5), an extraction type fan (6), a dust suction hood (7), a negative pressure air duct (8), a support rack (9), a suspension slideway (10) and a suspension support (12), wherein the suspension support is fixed at the tail of the belt conveyor, the suspension slideway is suspended on the suspension support, and pulleys (11) matched with the suspension slideway are mounted in the suspension slideway; the negative pressure air duct is divided into a fixed section connected with the dust suction hood and a telescopic section connected with the dry filter dust remover, the fixed section is fixed on the reversed loader through the support rack, and the telescopic section is suspended onto the suspension slideway through the pulleys. The heading face dry dust removing system has the advantages that high dust removing efficiency is coordinated with a heading process, the negative pressure air duct can move along with the heading machine, the work intensity of miners is lowered, the work efficiency of the miners is increased, and time and labor are saved.

Description

technical field [0001] The invention relates to a dust removal system, in particular to a dry dust removal system for an excavation face with a follower air duct support, and belongs to the technical field of mine roadway ventilation and safety. Background technique [0002] Due to factors such as narrow space, limited ventilation, and large dust production in underground working spaces such as coal mines and railway and highway tunnels, the dust concentration in the working space is high, which deteriorates the working environment and endangers the health of workers. With the improvement of coal mining mechanization, dust pollution in coal mine excavation work is particularly serious. However, the dust removal effect of traditional dust removal methods is poor. For example, spraying water not only has a weak ability to capture respirable dust, consumes a lot of water resources, but also causes secondary pollution to the working environment; foam dust removal agents are more...
