Dust, thus achieve the purpose that be classified atomizing de-dusting.
Further, the addition of above-mentioned dustfall agent mainly includes that dustfall agent fluid reservoir 10 and electronic addition pump 9 two parts,
Its main function is quantitatively to be added to depositing dust agent solution in dust-proof water pipe.Wherein, dustfall agent fluid reservoir 10 is a cylinder bodily form
Iron sheet container, volume 75L, with a thickness of 2cm.Aperture there are four settings at the top of it, respectively filling opening, are let out at relief valve port
Mouth and refluxing opening are pressed, is connected with a conical hopper above filling opening, facilitates liquid feeding, is connected with a safety above relief valve port
Valve plays the role of quick release pressure when hypertonia in dustfall agent fluid reservoir 10, and pressure relief opening is to maintain depositing dust
10 inside of agent fluid reservoir is communicated with ambient atmosphere, is facilitated internal gas to be discharged when to 10 inside liquid feeding of dustfall agent fluid reservoir, is returned
Head piece is to guarantee that the solution in electronic addition pump 9 fails to flow back into dustfall agent fluid reservoir when being completely added in foam device water pipe
10 inside are spare, are provided with inlet, liquid outlet and refluxing opening on electronic addition pump 9, inlet is connected with fluid reservoir, out liquid
Mouth is connected with the water pipe of foam device, and refluxing opening is connect with fluid reservoir refluxing opening by return pipe.Electronic addition pump 9 when work
Depositing dust agent solution in dustfall agent fluid reservoir 10 is sucked out and is pressurizeed, and then dustfall agent delivery pipe 11 is added by liquid outlet
Interior, liquid outlet pressure can continuously adjust between 0.5Mpa-5Mpa, and addition flow can be adjusted in 0-30L/min, work
Making voltage is 660/1120V.
Fully-mechanized digging machine fuselage of five distinguished and admirable jet blowers 4 around fully-mechanized digging machine cutterhead rear is uniformly distributed, and is cut apart from fully-mechanized digging machine
Cut the position of 2m or so around head, the distinguished and admirable outlet of each distinguished and admirable jet blower 4 is in crescent shape, width should 6mm-20mm it
Between, air outlet velocity should be between 10m/s-20m/s, to guarantee the distinguished and admirable fully wrapped around entire cutting area of energy that five nozzles spray
Domain forms cyclic annular air curtain together, cuts even if the air-flow that multiple distinguished and admirable jet blowers are formed is formed when colliding coal wall to fully-mechanized digging machine
The state for cutting head gathering will be wrapped near fully-mechanized digging machine cutterhead by the dust that foam and water mist capture, prevent it to tunnel
Rear diffusion, to play the purpose of closing dust, and repeatedly shearing depositing dust foam and depositing dust water mist.
In order to further illustrate the operation mechanism of the utility model, above-mentioned foam-water mist-air curtain three-level linkage drop is used
The process that dirt system carries out depositing dust side is as follows:
It works with fully-mechanized digging machine cutterhead, multiple bubble jet nozzles 1, multiple bulky grain atomized water spray mouths 2, multiple little particle water
Mist jet mouth 3 sprays simultaneously with multiple distinguished and admirable jet blowers 4；The depositing dust formation of foam foam dust suppression region that bubble jet nozzle spray 1 goes out
16, it is wrapped in fully-mechanized digging machine cutterhead and carries out depositing dust, when multiple bulky grain atomized water spray mouths 2 are sprayed, in fully-mechanized digging machine cutterhead
Front forms the first depositing dust region 17 of cover shape, when multiple little particle atomized water spray mouths 3 are sprayed, before fully-mechanized digging machine cutterhead
Rectangular the second depositing dust region 18 at cover shape when multiple distinguished and admirable jet blowers 4 are sprayed, forms cover in front of fully-mechanized digging machine cutterhead
The air curtain closed area 19 of shape, 19 domain of air curtain citadel is by foam dust suppression region 16, the first depositing dust region 17 and the second depositing dust area
Domain 18 is enclosed in fully-mechanized digging machine cutterhead dust region.
And rotated with fully-mechanized digging machine cutterhead, the depositing dust foam thrown away by fully-mechanized digging machine cutterhead is successively by the first depositing dust region
17, the second depositing dust region 18 is sheared with air curtain closed area 19, is formed depositing dust haze again and is wrapped in front of fully-mechanized digging machine cutterhead.
Especially, the air-flow that multiple distinguished and admirable jet blowers 4 are formed, which is in when colliding coal wall to fully-mechanized digging machine cutterhead, to be collapsed
State, the depositing dust water curtain that bulky grain atomized water spray mouth 2 and little particle atomized water spray mouth 3 are ejected rebounds back after encountering coal wall
Water mist shear atomization again, form depositing dust depositing dust haze and be wrapped in front of fully-mechanized digging machine cutterhead.
In particular, the air-flow that multiple distinguished and admirable jet blowers 4 are formed is in fully-mechanized digging machine cutterhead when colliding coal wall and collapses
State, generate excessive water mist when bulky grain atomized water spray mouth 2 and little particle atomized water spray mouth 3 are sprayed and shear mist again
Change, forms depositing dust depositing dust haze and be wrapped in front of fully-mechanized digging machine cutterhead.
That is, when fully-mechanized digging machine cutterhead works, under foam dust suppression, water mist dust fall and air curtain sealing process,
The dust that fully-mechanized digging machine cutterhead generates is wrapped near fully-mechanized digging machine cutterhead, prevents it from spreading to tunnel rear, to play
The purpose of dust, especially depositing dust water mist, depositing dust foam are closed by repeatedly shearing and under the sealing process of air curtain, is formed
The bigger depositing dust haze of concentration is greatly improved the concentration of depositing dust haze under same water, and then depositing dust is greatly improved
Efficiency indirectly reduces depositing dust cost.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model, are also answered
Belong to the protection scope of the utility model.
