Description
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 that provide one kind carries out dedusting using cyclone cylinder and water to dust caused by fully-mechanized digging machine
Fully-mechanized digging machine dust arrester.
To achieve these goals, the utility model includes, a cyclone cylinder, and a taper type is fixed in the cyclone cylinder
Hollow water distribution ring, the space between the bottom excircle of water distribution ring and the inner surface of cyclone cylinder is in the range of 1-5 millimeters, water distribution ring
Thickness be not more than 5 millimeters；
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.
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.
Further, the bottom of the slower conical tube of the cyclone cylinder connects with a drainpipe, and the drainpipe and one is except ashpit company
It is logical；
The top of the cyclone cylinder is connected with an exhaust duct, and the air outlet of the exhaust duct is stretched into except in ashpit；
The ashpit upper bands of removing have an overfall.
The water flowed out out of cyclone cylinder, which enters, remove ashpit, while the wind discharged from cyclone cylinder enters and removes ashpit, one side
The utilization rate of water is improved, on the other hand, final dusting is carried out to dust-laden wind.
Further, described except grid is fixed with ashpit, the inwall except ashpit, institute are close in the outer of the grid
State exhaust duct and pass through grid, and grid is close to the outer wall of exhaust duct.Exhaust duct can blow out substantial amounts of bubble in except ashpit,
Dust laden air can be discharged with bubble from except ashpit, without being contacted with water.Gas can be split and be adhered to increase grid
Bubble, the time and area that increase dust laden air contacts with water, improve efficiency of dust collection.
Preferably, the grid has multiple, and the lengthwise position of the contact jaw of grid and exhaust duct higher than its with except
The position of ashpit contact jaw, the lengthwise position of the overfall are higher than the peak of grid；
It is described except the top closure of ashpit, it carries an exhaust outlet, the air draft direction of exhaust outlet and the air intake of cyclone cylinder
In the opposite direction；
The drainpipe connects with the top except ashpit.
Multiple grids can reduce bubble diameter, improve bubble and water time of contact.In addition, nonplanar grid energy
Enough increase the area of grid, further improve efficiency of dust collection.Except ashpit is closed, its exhaust outlet is to cyclone cylinder air inlet opposite
Direction air draft, prevent the air after filtering to be directly entered cyclone cylinder, avoid energy waste.
Further, the air outlet of the exhaust duct carries an expansion mouth, the bottom of the expansion mouth with it is multiple uniformly
The distance between the tubule connection of branch, bottom surface of the bottom of the tubule with removing ashpit is not more than 5 millimeters.Tubule can reduce
Bubble diameter, improve and accumulated with water engaging surface.
Further, the cyclone cylinder and exhaust duct are connected by a necking of spurting.Necking of spurting can improve air-flow stream
Dynamic speed, avoids dust from being deposited in pipeline.
Further, in addition to a flow tank, the flow tank connect with overfall.Flow tank can settle dust, just
In recovery clean water.
