Abstract
The invention discloses a dense shallow hole dust catcher for coal mines, comprising a mixing box. The dense shallow hole dust catcher is characterized in that a drilling rod circular hole is processed on a rear plate of the mixing box; a dust guide pipe is communicated with the mixing chamber via a dust guide pipe circular hole; double spraying nozzles are arranged on a water feeding pipe of a top plate of the mixing box; and the bottom end of the mixing box is provided with a deslagging pipe which is connected into a whole with the mixing box. Wear-resistant sealing plates are fixed at the outer wall of the rear plate of the mixing box and at the periphery of the drilling rod circular hole. A flame-retardant liner is fixed at the inner wall of the dust guide pipe. A flame-retardant lining pad for supporting a twist drilling rod is fixed on a supporting plate of the mixing box. The dense shallow hole dust catcher has the advantages that a large amount of dust discharged from the drilling hole can be caught and collected, the clean air in a tunnel is remained, the effect is good, the operation is simple and practical, and spark generated by mutual friction of metal can be prevented and the like. The dense shallow hole dust catcher is mainly used for dust control of the dense shallow holes in head-on drainage construction of an underground electric coal drill for coal mines, and is especially applicable to dust collection of head-on drilling holes at gas explosion dangerous places.
Description
Technical field
The present invention relates to coal mine equipment, especially relate to a kind of colliery that can when miner's operation, solve dust removal problem in the tunnel 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 object of the present invention is to provide and a kind ofly 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 object of the present invention is achieved like this:
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 present invention 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 present invention has a large amount of dust that can catch collection and discharge from boring, 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 present invention 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.
