The utility model can also be able to further realization in the following manner simultaneously:
Preferably, described foaming mechanism comprises that foam maker and foam lay device, and described foam maker is laid device by foam pipeline and foam and is connected, and described foam laying device is arranged on a side that deviates from the heading machine cutting head working end.
Preferably, described air curtain forms mechanism and comprises spiral air flow generator and dust removing units, the air outlet of described spiral air flow generator straight up, and the air outlet of spiral air flow generator is arranged on the wall place near tunnel, development machine place; Described dust removing units comprises dust removal machine and suction port, and dust removal machine is connected by cleaning shaft with suction port, and described suction port is arranged on spiral air flow generator and foam is laid between device.
Further, described foam is laid device and is made of foam dispenser and foam nozzle, and described foam dispenser is in the form of annular discs, and described foam nozzle is provided with a plurality of, a plurality of foam nozzles all are connected with foam dispenser, and the spout of a plurality of foam nozzles is all towards the heading machine cutting head setting.
Further, described spiral air flow generator is arranged between foam maker and described suction port.
Further, the axis of described foam dispenser and the axis of heading machine cutting head coincide, and described foam nozzle is on the card of circular close heading machine cutting head one side that is distributed on foam dispenser.
The beneficial effects of the utility model:
1), the utility model utilizes spiral air flow generator, sets up together full section air curtain in development machine driver the place ahead, stops dust to locate diffusion to the driver.Suction port the place ahead installation foam nozzle at development machine, the high expansion foam that foam nozzle sprays carries out integral body to heading machine cutting head and covers, so just formed the froth bed of being isolated by air curtain in the driver dead ahead, thus stoped dust and foam to external diffusion; Dust and foam are in contact with one another in froth bed simultaneously, and dust is very fast wetting by foam, and final dust and foam suck and are excluded from suction port together.
2), dedusting method of the present utility model is submerged, it is also the dirt source that the foams of foaming mechanism ejection shroud heading machine cutting head, has stoped the diffusion of dust; Cumulative volume and the specific area of foams are large, have increased collision probability; Can also add surfactant in foam to increase wetability; For different coals, can also allot dissimilar surfactant to reach optimum wetting effect; The viscosity of foam is good, increases adhesive efficiency.
3), foam forms by air curtain the air curtain that mechanism produces and cuts off near heading machine cutting head, can arbitrarily not wave, and simultaneously due to the water that contains small amount in foam, after foam adheres to dust and falls earthward, can not make the underground work ecological deterioration.In sum, the utlity model has the advantages such as efficiency of dust collection is high, good dedusting effect, energy-conserving and environment-protective.
