Abstract
The utility model discloses a dust extractor with dense shallow holes for coal mine, comprising a mixing box, wherein the back plate of the mixing box is provided with a round hole of a drill rod, a dust guiding pipe is communicated with a mixing chamber through a round hole of the dust guiding pipe, a water supplying pipe on the top plate of the mixing box is provided with double spraying nozzles, the bottom end of the mixing box is provided with a slag discharging pipe integrally connected with the mixing box. A wear-resisting sealing plate is fixed around the outer wall of the back plate of the mixing box and the round hole of the drill rod. The inner wall of the dust guiding pipe is fixed with an anti-flaming lining. The support plate of the mixing box is fixed with an anti-flaming gasket for supporting a twisted drill rod. The dust extractor with dense shallow holes for coal mine collects much dust discharged from the drill hole to keep fresh air in the channel, is easy to use, and can prevent sparkles caused by mutual frication of metals. The dust extractor with dense shallow holes for coal mine is mainly used for treating dust of the dense shallow holes from head-on drainage in coal drill construction in the pit, especially for removing dust of head-on drill hole at the dangerous place with gas.
Description
Technical field
The utility model relates to coal mine equipment, especially relates to a kind of colliery that can solve dust removal problem in the tunnel when miner's operation with intensive shallow bore hole grit arrestor.
Background technology
At present, under coal mine, carry out coal road when driving and adopt the meet head on mode of the intensive shallow bore hole of extraction of construction to come pre-gas pumping usually, preventing gas burst accident, thereby reach the purpose of the gas comprehensive regulation.The miner adopts the 2.2KW electric coal drill to carry out dry drilling, though the dust of from boring, discharging in hell by the dedusting of sprinkling water, but poor effect, still cause dust from flying in the tunnel in the same old way, miner's working environment is extremely abominable, have a strong impact on the healthy of miner, also be unfavorable for the safety in production in colliery.Because of the 2.2KW electric coal drill does not have water filling device, and to execute the drilling rod that bores usefulness be the twist drill rods of diameter 70mm, so more increased the difficulty of dedusting.
Summary of the invention
The purpose of this utility model is to provide a kind of can continuously catch a large amount of dust that collection discharges from boring, keep with fresh air, respond well, simple in structure in the tunnel, install and use easy, cost of manufacture is low and can prevent that colliery that the mutual friction of metal phase produces spark is with intensive shallow bore hole grit arrestor.
The purpose of this utility model is achieved in that
A kind of colliery is with intensive shallow bore hole grit arrestor, comprise blending bin, feature is: be processed with the drilling rod circular hole that allows the twist drill rods of 2.2KW electric coal drill pass on the back plate of blending bin, on the header board of blending bin, be processed with the dust guiding tube circular hole, the rear end of cylindrical shape dust guiding tube is fixed on the header board of blending bin, and see through the interior mixing chamber of dust guiding tube circular hole and blending bin and communicate, the water inlet pipe that links to each other with water pipe is installed on the top board of blending bin, delivery port at water inlet pipe is equipped with the two spray nozzles that are located in the mixing chamber, is provided with the deslagging pipe that is connected as a single entity with blending bin in the bottom of blending bin.
Around the back plate outer wall of blending bin, drilling rod circular hole, be fixed with the wear-resistant seal plate.
Inwall at dust guiding tube is fixed with fire-retardant liner.
Below the back plate outer wall of blending bin, drilling rod circular hole, supporting plate is installed, on supporting plate, is useful on the fire-retardant liner that supports twist drill rods by bolt.
The utility model is the blending bin that is with band dust guiding tube and two spray nozzles at the front end of the twist drill rods of 2.2KW electric coal drill.Earlier 2.2KW electric coal drill and twist drill rods are placed in the blending bin that is installed in drilling cramp track front end before using, and dust guiding tube is close to the coal wall, during work, the starting electric coal drill, along with drill bit and twist drill rods constantly creep into forward, the dust that discharge on twist drill rods spiral limit directly enters in the mixing chamber of grit arrestor by dust guiding tube, at this moment two spray nozzles at mixing chamber top spray water smokes, form the water curtain that surrounds dust, dust is lived in interception, makes its rapid humidifying sedimentation, then by the slag outlet below the blending bin, automatically successively discharge, thereby reach the purpose of dedusting.Wear-resistant seal plate, fire-retardant liner and fire-retardant liner can prevent metal mutual friction generation spark mutually.Therefore, the utlity model has a large amount of dust that can catch collection and from boring, discharge, keep with fresh air, respond well, simple in structure in the tunnel, install and use easy, compact overall structure, practicality simple to operate, cost of manufacture is low and can prevent that the mutual friction of metal phase from producing the advantage of spark, the utility model is mainly used in the meet head on treating flour dust of the intensive shallow bore hole of extraction of the construction of electric coal drill under the coal mine, is specially adapted to have the dedusting of holing of meeting head on of methane gas explosion hazard area.
