Description

Fully-mechanized digging machine fast dust-removing device

Technical field

It the utility model is related to a kind of comprehensive tunneler auxiliary equipment, and in particular to a kind of dust arrester.

Background technology

Colliery is the mankind in the region of the mining area exploitation coal resources rich in coal, is generally divided into underground mine and outdoor coal Ore deposit.When coal seam is remote from earth's surface, it is typically chosen to underground and digs tunnel digging coal, this is underground mine.When coal seam is away from earth's surface Distance it is close when, be typically chosen and directly peel off surface soil layer and excavate coal, this is open coal mine, China overwhelming majority colliery category In underground mine, according to different mining geology and technical conditions, there can be different coal mining systems to be engaged with coal winning technology, from And form diversified coal-mining method.Such as under different geology and technical conditions, longwall system, pillar can be used to adopt Coal method or other coal-mining methods, and longwell is with the pillar method of working that the difference in terms of coal mining system with coal winning technology is very big.Coal mining When usually use fully-mechanized digging machine, fully-mechanized digging machine is the abbreviation of comprehensive mechanized development machine, is a kind of set driving, muck, fortune The coal comprehensive mechanization equipment that even supporting, screw way multiple functions are integrated, after typically using comprehensive mechanized driving, is compared The piercing technique relatively drilled and blasted, driving progress can be increased by more than 30 times.But fully-mechanized digging machine is when in use, due to work( Rate is larger, and dust can be flown upward when fully-mechanized digging machine works in colliery, and while bringing environmental pollution, colliery dust can cause It is fried so that coal mining has very big danger.

Also there is the equipment that dedusting is much carried out to fully-mechanized digging machine in the prior art.For in major class, it is divided into two kinds, one kind is profit Dust is taken in dust arrester installation with wind suction, another kind is to utilize water to adhesion to absorb dust.

Such as Chinese patent CN201620626445.5, notification number in wherein the first major class：CN205714195U, title " one Dust arrester of the kind for colliery fully-mechanized digging machine ", disclose a kind of equipment being pumped in using wind-force using electric dust arrester installation dedusting. This kind equipment, the efficiency comparison of dedusting is low, abnormally dangerous using electrostatic dust collection in underground, and high, the efficiency that consumes energy of being gathered dust using bag Low, dust collecting sleeve needs periodic detection and replacing.

In second class, such as Chinese patent, 201620518886.3, notification number：205778983U, title " annular geomantic omen connection It is dynamic to catch dirt curtain atomizing de-dusting apparatus ", such device utilizes water, mist or the bubble adhesion dust ejected.Effect is very bright in short-term It is aobvious, but after water is dry, machine operation can cause reentrainment of dust.

Also occurs the new technology with reference to this two class now.Such as Chinese patent 201510700680.2, publication No. CN105251301A, title " a kind of from sharp Whirlwind wet collector ", it discloses a kind of using cyclone cylinder and into cyclone cylinder The mode of water spray carries out dedusting, and this mode can more effectively carry out dedusting, but its spray mode is to be directly sprayed onto water In cyclone cylinder, the flowing of air-flow can be so upset, and the contact surface of water and dust is very small, the effect of water and unobvious.

The content of the invention

The purpose of this utility model is to provide a kind of fully-mechanized digging machine for carrying out dust caused by fully-mechanized digging machine using water dedusting Fast dust-removing device.

To achieve these goals, the utility model removes ashpit including one, and the ash disposal bottom of pond end is provided with water inlet, described Except the upset ash disposal net of the default position of ashpit one, the upset ash disposal net includes a rotating shaft, multiple grids is uniformly fixed in rotating shaft, Described rotating shaft one end, which is stretched out, removes ashpit, and is fixedly connected with the output end of motor, described except ashpit carries an overfall；

The grid is rectangle, and its width is not less than 5 centimetres, plane where it and the diameter parallel of rotating shaft；

Also including an exhaust column, the air outlet of exhaust column expands neck to upset ash disposal net air draft with an expansion neck, Expansion neck spout is rectangle, and its length is equal to the length of grid, and width is less than twice of grid width；

The overfall is located in the upper end centimetre of rotating shaft.

Grid is ceaselessly overturn under the drive of rotating shaft, is taken out of from except ashpit and is adhered to water formation moisture film, exhaust column Dust-laden wind is blowed to grid, moisture film quickly adheres to dust-laden wind, so as to reach the effect of fast dust-removing.

Further, in addition to a cyclone cylinder, a hollow water distribution ring of taper type, water distribution ring are fixed in the cyclone cylinder Bottom excircle and cyclone cylinder inner surface between space in the range of 1-5 millimeters, the thickness of water distribution ring is no more than 5 millis Rice；

Also include an overflow ring, overflow ring is located between the conical surface and cyclone cylinder of water distribution ring, in addition to water inlet, enters The mouth of a river connects with overflow ring；

The bottom of the slower conical tube of the cyclone cylinder connects with a drainpipe, and the drainpipe and one is except the water inlet company of ashpit It is logical；

The top of the cyclone cylinder connects with exhaust column；

Described to remove ashpit top closure, top is provided with a gas outlet, gas outlet outgassing direction and cyclone cylinder air intake direction Conversely.

Water inlet introduces the water into overflow ring, and water is flowed on water distribution ring by overflow ring into circle, is flowed to and revolved by water distribution ring On the inwall of air duct, uniform moisture film is formed on the inwall of cyclone cylinder.The wind of dust is swept along in cyclone cylinder internal rotation, particle quilt Get rid of to cyclone cylinder barrel, moisture film quickly adhered particles and can be taken away, and efficiency of dust collection greatly improved.Utilize overflow ring and water distribution Circle can improve the area of water to greatest extent, and not interfere with flowing of the wind in cyclone cylinder.So can further it carry High efficiency of dust collection.

Further, connected between the grid middle part by horizontal grid.Moisture film area can so be increased, carried High dust removing effects.

Further, the cyclone cylinder and exhaust column are connected by a necking of spurting.Necking of spurting can improve air-flow stream Dynamic speed, avoids dust from being deposited in pipeline.

Also include a flow tank, the flow tank connects with overfall.Flow tank can settle dust, be easy to recovery clean Water.
