Described ejector is made up of jet dish, jet pipe, the jet dish is installed in an end of jet pipe, be provided with cavity in the jet dish, the through hole of cavity on jet dish outer wall is connected with atomizing pump, the inwall of jet dish is provided with a plurality of end fluid jet nozzles that are communicated with cavity, and jet pipe is fixedly connected with the bottom of dust arrester and be communicated with dust arrester.
Above-mentioned mining drill orifice dust catcher also is provided with fluid jet nozzle at least 1 pipe in the described jet pipe, fluid jet nozzle is communicated with cavity in the jet dish by pipeline in the pipe; Fluid jet nozzle, end fluid jet nozzle place the both sides of dust arrester lower end outlet respectively in the pipe.Purpose is to increase effluxvelocity effectively, improves efficiency of dust collection.
The beneficial effects of the utility model are: the utility model adopts and be provided with annular air curtain device in dust arrester, can be effectively the dust in the hole of drilling be blocked in the dust arrester, avoid dust to discharge from the gap between drilling rod and the dust arrester rear wall, the dust arrester front side closely contacts with the coal seam wall, operation does not have the purpose that dust leaks thereby the realization work plane is drilled, and has improved operating environment effectively.
Adopt ejector, use high-pressure water mist or high-pressure blast to spray, make and form negative pressure in the dust arrester, in the dust of directly will the hole suction flow type pump with injection pipe, in jet pipe dust through water smoke or high-pressure blast discharging jet pipe, thereby reach the purpose of dedusting.Both save the water source, avoided airborne dust again.
Adopt and also be provided with fluid jet nozzle at least 1 pipe in the jet pipe.Can increase effluxvelocity effectively, improve efficiency of dust collection.
The utility model efficiency of dust collection height, simple to operate, easy to use, low in energy consumption, water consumption is few.Can greatly improve the air ambient at bore operation scene, help the operator physical and mental health, increase work efficiency.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following manual, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
