Along with the fast development of China's economic construction, coal industry is constantly towards the future development of mechanization, automation, and comprehensive mechanical coal mining equipment is applied among the coal production of various geological conditionss more and more widely.But mechanization degree improves constantly along with mining work, and digging amount is excessive, face dust concentration is constantly increased, if do not taked effective dust suppression, the dust of high concentration is by the Diffusion of gas stream along with pressure people tunnel, have a strong impact on the healthy of constructor, and in the time that coal dust reaches finite concentration, there is naturality with explosive, the production safety that seriously threatens mine.Therefore, generally all can be provided with dust arrester in various tunnelling equipment, dust arrester is one of core system of coal excavation apparatus, and its performance directly has influence on the quality of coal excavation apparatus.
Wherein continuous miner can produce a large amount of dust in coal mining process, and along with the continuous increase of power, although significantly improved the drawing speed of tunnel work plane, has also caused rolling up of dust.Continuous miner is because cutting speed is fast, cut area is large, cut decentralization high, the dirt source of its getting working face is increased, the Dust Capacity producing is large, and the haulage vehicle such as mine car, shuttle car that coordinates continuous miner to use has also increased the concentration of dust to a certain extent, if adopt traditional spray for dust suppression measure to be difficult to be resolved.
Utility model content
The purpose of this utility model is just to provide a kind of continuous dust arrester of coal-winning machine, improves the dust removing effects of continuous miner.
In order to reach above-mentioned effect, the utility model provides a kind of continuous dust arrester of coal-winning machine, it is characterized in that: comprise the air duct of being located at rocker arm of coal mining machine top and rotating with the cutting drum of coal-winning machine, the air outlet of described air duct and the sweep-up pipe of deduster are rotated and are tightly connected, and the discharge pipe of described deduster is sealedly connected with negative-pressure air fan; Described deduster and negative-pressure air fan are fixedly arranged on the fuselage of coal-winning machine.
Further, described air duct comprises cylindrical shell and air outlet, is provided with at least four blower fans in described cylindrical shell, the left, right, front and rear of being located at respectively cylindrical shell of described four blower fans, and their air-out meets at the air outlet place of air duct.
Preferred version of the present utility model is to be also provided with a blower fan on the top of cylindrical shell, makes pick-up performance better.
Further, described deduster is wet scrubber, comprises the sweep-up pipe, spray tank, Rose Box, scrubbing case and the discharge pipe that are communicated with successively; The end of described spray tank is provided with the nozzle being connected with water pipe, is provided with screen pack in Rose Box, and scrubbing case centre is provided with drop separator, bottom is provided with sewage draining exit.
Further, the centre of gyration of the centre of gyration of described air duct and the cutting drum of coal-winning machine is consistent.
Rocker arm of coal mining machine, by the motor power after slowing down, pass to cutting drum to carry out coal cutting, and coal cut being got off by the helical blade on cylinder installs on working face conveyor.
The dust producing while work due to coal-winning machine mainly collects in cutting drum around, the utility model is respectively established a blower fan at the four sides, left, right, front and rear of the cylindrical shell of air duct, to collect and converge at the air outlet of air duct from all directions through the broken dust producing of cut from face, its dust suction amount is large and complete, reduces the harm of dust to human body or secure context.In addition because air duct is to rotate with the cutting drum of coal-winning machine, thereby the dust as much as possible coal-winning machine being produced all collects, and has ensured the effect of dedusting.
The utility model adopts dust that wet scrubber collects air duct through sedimentation, filtration and separates the operation of multiple working procedure, and whole the particle in dust sedimentations are discharged from sewage draining exit, has improved dust removing effects.Clean gas is discharged from negative-pressure air fan.The blower fan adopting is negative-pressure air fan, and by the inner continuous devision device negative pressure that forms, the dust that air duct is sucked produces the power advancing to wet scrubber.
