Abstract
The present invention relates to dust pelletizing system during the work of excavation face in coal mine fully-mechanized digging machine, it produces dusting problem when can efficiently solve the work of excavation face in coal mine fully-mechanized digging machine.Its structure is, is made up of foamed system, defoaming system.Due to the fact that employing said two devices structure is debugged, the coupling of foamed system, defoaming system can make foam that the cutterhead of fully-mechanized digging machine is surrounded and don't bulk deposition, the foam of cutterhead surrounds cutterhead all the time, safe and reliable, significant to excavation face in coal mine dedusting.Present configuration system is simple, novel, unique, dust can be made not fly upward, be inherently eliminated dust from flying, is that the one of excavation face in coal mine dedusting industry innovates greatly, and popularization and application have great Social benefit and economic benefit.
Description
Technical field
The present invention relates to field of coal mine safety, particularly excavation face in coal mine fully-mechanized digging machine dust pelletizing system.
Background technology
At present, excavation face in coal mine fully-mechanized digging machine dust pelletizing system in colliery, various countries is to use forced or exhaust ventilation
It is diluted.He is that one dilutes dust passively and do not carries out dust elimination, simply cures the symptoms, not the disease.This
Planting dilution powder dust collecting method and can not eliminate dust in real time, people can work the mischief in suction body in the same old way, and colliery is combined
Pick work surface is badly in need of the dust pelletizing system of a kind of real-time elimination dust.
Summary of the invention
For above-mentioned situation, the purpose of the present invention is exactly to be to provide the colliery of a kind of real-time elimination dust to combine pick work
Making face fully-mechanized digging machine foam dedusting system, this dust pelletizing system is that it can realize eliminating fully-mechanized digging machine operating in real time and cut
The dust produced when cutting rock and coal seam.
A kind of excavation face in coal mine fully-mechanized digging machine foam dedusting system, it is characterised in that cutting at fully-mechanized digging machine cutterhead
Cut foamed system equipment and the defoaming system equipment installed on arm.The two coupling makes foam just be surrounded by cutterhead
Get up, and foam not bulk deposition.When making cutterhead cut rock and coal seam, dust can not fly upward.Really
Eliminating dust at cutterhead, dust becomes big due to the effect of the foam granule that sticks together, and loses the ability of flying upward.
Even if automation examination, owing to dust granules becomes big, it is bonded at tunnel and cutterhead, also can not blow.
Practicing of excavation face in coal mine fully-mechanized digging machine foam dedusting system, substantially increases colliery and combines pick work
Make the working environment sanitary condition in face, alleviate the working environment that coal miner suffers from pneumoconiosis.To instructing colliery
Safety in production and colliery harmonious development are significant.It is greatly reduced mechanical wear simultaneously, has improve
In the service life of machinery, be that in terms of coal mine dedusting innovates greatly, and popularization and application have great social meaning
And economic implications.
Accompanying drawing explanation
Invention discussed above aspect and other features are retouched hereinafter in conjunction with relevant drawings
State, wherein:
Fig. 1 is the present invention at the foaming of cutting units and defoaming system planar structure schematic diagram
Fig. 2 is the present invention foaming at cutting units and the generalized section of defoaming system.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail.
Being given by Fig. 1, Fig. 2, the present invention by its structure is, by the cutterhead of fully-mechanized digging machine, foamed system, froth breaking system
System composition.Due to the fact that employing foamed system, both defoaming systems foaming machine are debugged, make foaming system
The coupling of system, defoaming system can make foam that the cutterhead of fully-mechanized digging machine is surrounded and foam not bulk deposition, cut
The foam of head surrounds cutterhead all the time, safe and reliable,
Foamed system by foam nozzle (1), regulation valve (3), foam solution pipeline (18), foam maker (11),
Foam blender (10), add pump (7), foam (8), effusion meter (4), Pressure gauge (5), open
Close (6), fully-mechanized digging machine pressure wind apparatus (14), fully-mechanized digging machine water supply installation (15) composition.
Defoaming system froth breaking shower nozzle (2), regulation valve (3), froth breaking liquid pipeline (19), froth breaker (13),
Add pump (7) defoamer (9) defoamer blender (12), effusion meter (4), Pressure gauge (5), switch
(6), water pump (15) composition.
The target of the present invention is realized by following measures: the present invention is cutterhead (16) product at fully-mechanized digging machine
During fecula dirt, the shower nozzle (2) of foamed system dust is wrapped in cutterhead (16) and makes powder by the foam produced
Dirt can not fly upward；And the foam that the shower nozzle of the defoaming system of outside (2) sprays sprays to the shower nozzle (1) of foamed system
The foam produced makes the substantial amounts of foam in cutterhead (16) portion through reducing accumulation, such warp after dust effect
Cross the foam that the foam that the shower nozzle (1) of foamed system sprays sprays with the shower nozzle (2) of defoaming system to couple and make
The foam of cutterhead (16) can not bulk deposition.Not only save a large amount of under conditions of such two kinds of foams coupling
Water resource and also driving face is the moistest, the comfortable working environment of workman, so work surface vision is good,
Labor efficiency is high, the generation of minimizing accident.Driving face environment the most also extends the service life of machinery.
This excavation face in coal mine fully-mechanized digging machine foam dedusting system is simple to operate, can save substantial amounts of water resource,
Substantially increase driving face efficiency of dust collection, safe and reliable, Safety of Coal Mine Production is of great importance.This
Inventive structure is simple, novel, unique, also improves the safety of people simultaneously, is that driving face in coal mine removes
The one of dirt technology innovates greatly, and popularization and application have great Social benefit and economic benefit.
