Description
Technical field
The utility model relates to a kind of dust arrester of girdle, relates in particular to a kind of dust arrester of thin seam mining work plane.
Background technology
Falling fume and dust behind the underground mining face firing of colliery, is the important step in the mining sequence.On the existing market fume and dust atomization mechanism falls, equipment integral body is bigger, mainly be applicable to and fall the fume and dust operation on the high seam large working area, and for the exploitation work plane of girdle, generally be not establish device for reducing dust and wait for the nature depositing dust, coal-face is below 0.8m, and by coal-winning machine or artificial directly exploitation, dust is big.
China Patent No. ZL200620010010.4 discloses the device for reducing dust that a kind of name is called " the multi-functional automatic sprayer of blasting mining in thin seam work plane ", this device is to be connected with supply channel before main frame, and supply channel is provided with supply channel water booster system and stop valve, adopt the weak point of this atomizing de-dusting apparatus to be: use ground, back can form a lot of coal slimes, personnel's turnover is transported very inconvenient.
The utility model content
The purpose of this utility model provides a kind of thin seam mining work plane dust arrester, does not establish dust arrester or adopts the problem that atomizing de-dusting apparatus was brought to solve prior art.
For achieving the above object, the utility model adopts following technical scheme: a kind of thin seam mining work plane dust arrester, this device is included in the set airduct across the coal face direction in hydraulic support below, be provided with explosion-proof dedusting fan in the top of coal-face string on the described airduct, airduct is provided with at least one air intake; Be respectively equipped with atomization mechanism in the air intake and the air side of explosion-proof dedusting fan in the described airduct.
Described explosion-proof dedusting fan is by electromagnetic switch and main controller control, and the control input end of described electromagnetic switch is connected with the signal output part of main controller, and the signal input part of described main controller is provided with the sensor of controlling as automatically.
Described explosion-proof dedusting fan is installed on and is used to carry directly over the fortune coal belt of coal.
Set shower nozzle is formed on supply channel that described atomization mechanism is established by the coal-face place and the supply channel.
Be provided with strainer and electromagnetic valve and pressure pump successively on the described supply channel before shower nozzle, the control input end of described electromagnetic valve is connected with the signal output part of described main controller.
Described sensor adopts dust sensor or start-stop sensor or acoustic control sensor or light control sensor or touch sensing or wireless touch sensing.
Thin seam mining work plane dust arrester of the present utility model is taken dust away by explosion-proof dedusting fan, high concentrate dust can enter airduct inside as soon as possible, and atomizing de-dusting is carried out in the rear end before blower fan. after getting wet, coal dust forms coal slime, reach the purpose of depositing dust, reduce the dust concentration of coal-face, reduced the possibility of anthraco-silicosis and dust explosion.
In addition, the coal slime that forms directly is discharged on the fortune coal belt, coal dust is utilized, avoid coal dust is fallen on the ground, form the secondary dust in the future again.
Description of drawings
Fig. 1 is an airduct structural representation of the present utility model;
Fig. 2 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is done further introduction.
Be the structural representation of the utility model thin seam mining work plane dust arrester as depicted in figs. 1 and 2, this device is included in the set airduct 2 across the coal face direction in hydraulic support below, be provided with explosion-proof dedusting fan 1 in the top of coal-face (being the return airway road junction among Fig. 1) string on the airduct 2, airduct 2 is provided with among a plurality of air intake 3(present embodiment Fig. 1 and is illustrated as 5); Is respectively equipped with atomization mechanism in the air intake and the air side of explosion-proof dedusting fan 1 in the described airduct, set shower nozzle 8 is formed on supply channel that atomization mechanism is established by the coal-face place and the supply channel.Explosion-proof dedusting fan 1 is by electromagnetic switch 9 and main controller 10 controls, and the control input end of electromagnetic switch 9 is connected with the signal output part of main controller 10, and the signal input part of main controller is provided with the sensor of controlling as automatically 11.In order to guarantee the cleaning of down-hole spray water, therefore strainer 6 is set at the supply channel water inlet; In order to make the even more ideal and realization automatic water jetting control of atomizing de-dusting effect, on the supply channel with before the shower nozzle pressure pump 7 and electromagnetic valve 5 are set, the control input end of electromagnetic valve 5 is connected with the signal output part of described main controller 10.In order to adapt to the actual conditions of down-hole coal excavation environment, the sensor of present embodiment adopts dust sensor.
In addition, explosion-proof dedusting fan 1 is installed on and is used to carry directly over the fortune coal belt 4 of coal, and coal dust forms coal slime under nebulization, can directly drop on the fortune coal belt 4 and carry, and prevents from that coal slime from falling to the ground to form the secondary dust again after air-dry.
The utility model is applicable to the coal-face that highly is lower than 1m, and special-purpose explosion-proof dedusting fan is installed in the coal-face top, and the airduct of airduct is positioned under the hydraulic support and corner.Like this, the coal dust of corner and work plane carries out atomizing de-dusting through flowing through the distinguished and admirable airduct inside that enters airduct of work plane herein in the front-end and back-end of explosion-proof dedusting fan, and coal dust is formed coal slime or coal cinder, pours on the fortune coal belt, is delivered on the ground.
The advantage of the utility model thin seam mining work plane dust arrester is: (1) is taken dust away by explosion-proof dedusting fan, high concentrate dust can enter airduct inside as soon as possible, and atomizing de-dusting is carried out in the rear end before blower fan. after getting wet, coal dust forms coal slime, directly drop on the fortune coal belt, coal dust is utilized, rather than coal dust is fallen on the ground; (2) dust concentration of reduction work plane, the possibility of minimizing anthraco-silicosis and dust explosion; (3) because the volume of airduct is little, it is little to take up room, and does not influence normal coal mining.
Sensor can also adopt start-stop sensor, acoustic control sensor, touch sensing etc. in the present embodiment except that adopting dust sensor, and setting is gone up in place; Electromagnetic valve also can adopt ball valve, and this similar conversion belongs to those skilled in the art's common technology means, drops within the protection domain of the present utility model.
