Abstract

The utility model discloses a rock tunneling spray blocking associated dust prevention and dust settling device. An arched high pressure water pipe is arranged along the roadway arched roof, and a row of sprayers for spraying water towards inner side and outer side of the roadway are uniformly arranged on the high pressure water pipe; an iron wire is drawn between the arched points at two sides of the roadway, a folio compact dust prevention net is hung on the iron wire by a hanging ring, the folio part of the folio compact dust prevention net is locked by a buckle, the roadway arched section is further provided with an arched compact dust prevention net for sealing. When in use, a water curtain switch is turned on, the oppositely pulling compact dust prevention net is hung, spraying dust prevention and dust prevention net dust settling effect at the same time, a high pressure spraying device forms water curtain barriers in front and behind the net, a layer of net in the middle absorbs the dust and plays a role in dust settling, the first water curtain layer plays a role in dust prevention, the second compact net layer plays a role in dust prevention and dust settling, the third water curtain layer plays a role in dust removal, the dust prevention measures are distributed in the whole roadway section, thus, a three-layer spatial three-dimensional dust prevention and dust settling effect is realized.

Description

The stone drifting spraying intercepts unites anti-, device for reducing dust

Technical field

The utility model relates to mining industry field stone drifting work plane device for reducing dust.

Background technology

The coal master will open up large lane and preparatory working generally all designs in the rock stratum, and drift section is arch.The dust that produces in the tunnelling process, to the healthy of miner with caused great harm, the control of strengthening dust hazard is the extremely important aspect of Safety of Coal Mine Production.In order further to reduce dust harzard, purify distinguished and admirablely comprehensively, must meet head on to carry out strict depositing dust to driving face.The measurements for reduction such as present driving face has mainly been taked purification water curtain, the big gun district's spraying of meeting head on.Because the spray atomization effect is not fine, can not stop whole section, cause dust concentration to transfinite, bring threat for mine safety production and worker's life and health.

Summary of the invention

The purpose of this utility model is the treating flour dust problem when solving driving, proposes a kind of stone drifting spraying obstruct and unites anti-, device for reducing dust.

For achieving the above object, the technical scheme that the utility model is taked is:

A kind of stone drifting spraying intercepts unites anti-, device for reducing dust, it is characterized in that, it is to arrange an arch high-pressure water pipe along tunnel arch top board, evenly is provided with a shower nozzle discharged to both sides water spray inside and outside the tunnel on high-pressure water pipe; Become between apsis at roadway's sides and draw an iron wire, hang the fine and close Air Filter of opposite opened one with suspension ring on iron wire, the position of splitting of the fine and close Air Filter of opposite opened interlocks with latch closure and reaches the effect of closed lower face, establishes one fine and close Air Filter sealing of arch on the crowned section of tunnel again.

The utility model has the advantages that: when tunnelling is used, open the water curtain switch, pull on the fine and close Air Filter to drawing, spray dust prevention and Air Filter dust fall work simultaneously, and high pressure sprays fog equipment forms the water curtain barrier after netting simultaneously before net, there is one deck net absorption dust the centre and plays the depositing dust effect, the first floor water curtain is dustproof, the second layer dense mess depositing dust that prevents dust, the 3rd layer of water curtain dedusting, whole dust prevention is full of drift section, reaches the effect of the three-dimensional dustproof depositing dust of three sheaf spaces.When used time not, move Air Filter to tunnel a gang of stop, do not hinder the pedestrian to drive a vehicle.

In figure: 1-high-pressure water pipe, 2-shower nozzle, the fine and close Air Filter of 3-arch, 4-iron wire, 5-suspension ring, the fine and close Air Filter of 6-opposite opened, 7-latch closure.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of stone drifting spraying intercepts unites anti-, device for reducing dust, and it is to arrange a high-pressure water pipe 1 along tunnel arch top board, evenly is provided with a shower nozzle 2 discharged to both sides water spray inside and outside the tunnel on high-pressure water pipe 1; Become between apsis at roadway's sides and draw an iron wire 4, hang the fine and close Air Filter 6 of opposite opened one with suspension ring 5 on iron wire 4, the position of splitting of Air Filter 6 interlocks with latch closure 7; Seal with one fine and close Air Filter 3 of arch again on the crowned section of tunnel.

Claims

1. a stone drifting spraying intercepts and unites anti-, device for reducing dust, it is characterized in that, it is to be furnished with an arch high-pressure water pipe along tunnel arch top board, evenly is provided with a shower nozzle discharged to both sides water spray inside and outside the tunnel on high-pressure water pipe; Become between apsis at roadway's sides and establish an iron wire, be hung with the fine and close Air Filter of opposite opened one with suspension ring on iron wire, the position of splitting of the fine and close Air Filter of opposite opened interlocks with latch closure, is provided with one fine and close Air Filter sealing of arch on the crowned section of tunnel again.
