Abstract
The invention discloses a coal mine negative pressure dust extraction device which comprises a dust remover shell. An air inlet is formed in the lower portion of the dust remover shell, and the air inlet is connected with a dust collecting hood through pipelines. An air outlet is formed in the upper portion of the dust remover shell, and the air outlet is connected with a negative pressure generator. A filter device is arranged between the air inlet and the air outlet. A dust discharging port is formed in the bottom of the shell, and the dust discharging port is provided with an opening and closing valve. The coal mine negative pressure dust extraction device has the advantages that dust removal effects are good, production cost is low, and the coal mine negative pressure dust extraction device does not need water or foam.
Description
Technical field
The present invention relates to coal mine equipment field, is a kind of dust arrester specifically.
Background technology
In coal production, produce a large amount of dust, this dust not only causes great injury to direct labor's health, and dust explosion very easily occurs, and therefore, the dust of eliminating in coal production is the necessary condition of coal production.Prior art is to adopt the method for water spray that dust is combined with liquid, thereby eliminates dust.The method need to be equipped with special water system, the coal mining activity place that inapplicable water source lacks, in addition, because large water gaging in producing is sneaked in unearthed coal, not only reduced product quality, and caused airborne carrier to work in a humid environment for a long time, very easily damaged, thereby increased cost, adopt the method for foam dust elimination as disclosed in Chinese Patent Application No. 2008100235779, the method structure is: a kind of foam generator for coal mine dedusting, it comprises cylindrical shell, air inlet pipe, the small air inlet hole of offering on Venturi tube and Venturi tube diffuser, described cylindrical shell is by venturi socket, the foam obstacle cylinder and the tail pipe that are connected in respectively venturi socket two ends by flange form, in the diffuser of described Venturi tube, be fixed with a flow spoiler, flow spoiler is fixed on the connection place of venturi socket and foam obstacle cylinder by fixed support, in foam obstacle cylinder, be interval with the polylith balk board interleaving up and down.Although this technology is dust elimination dust to a certain degree, need expend a large amount of foams, cost is higher, inapplicable large-scale production.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of pneumatic dust collection effective, producing cost is low, does not need the dust arrester of water power and foam, and concrete technical scheme is as follows:
A kind of colliery negative pressure dust removing device, comprises shell of dust remover, and the bottom of described shell of dust remover arranges air intake, and described air intake is connected with dust gathering arrester by pipeline; The top of described shell of dust remover sets out air port, and described air outlet is connected with negative pressure generator; Between described air intake and air outlet, filter is set; The bottom of described housing arranges dust-exhausting port, and described dust-exhausting port arranges switching valve.
Also involving vibrations device, described vibrating device is arranged on shell of dust remover, and described filter recycles the dust of retrieving in time by vibration.
Described switching valve is pneumatic control valve.
Described air outlet and negative pressure generator corresponding position arrange pneumatic Venturi tube.
Described vibrating device comprises air motor, cam, extension spring, and described air motor is fixed on motor base, and described motor base is fixed on shell of dust remover; Described motor driving cam rotates, the framework butt of described cam and filter, and the two ends of described extension spring connect respectively framework and the motor base of filter.
Described filter comprises the filter screen of bottom and the filter cloth on top, and the framework of described filter screen and filter cloth is fixed into one the cam butt with vibrating device.
In described dust-exhausting port, Inductance valve is set, the dust accumulation altitude signal sensing is passed to control centre by described Inductance valve, and then control pneumatic operated valve and open, and described pneumatic operated valve control opens and closes valve.
Advantage of the present invention is: good dedusting effect, producing cost is low, does not need the dust arrester of water and foam.
