Description
Technical field
The utility model relates to a kind of adjustable air duct, particularly relates to a kind ofly to be applicable to the adjustable air duct that pick face dust prevention and control combined by mine.
Background technology
The domestic and international control to fully mechanized workface dust disaster at present, in main employing development machine, wetting agent, deduster dedusting, ventilation dust discharge and foam dust suppression technology are added in external spraying, chemical dedusting.In deduster dedusting, one of key point is drawn in deduster by dust, then carries out process sedimentation.Be limited to tunnel wind speed requirement and prevent the needs of circulated air, the exhausting amount of deduster can not be too large, and the high speed winds of forced air duct fails to be convened for lack of a quorum and produces very big disturbance to wind flow field of meeting head on simultaneously, can reduce suction Dust Capacity like this, reduce dust-laying effect.
For effective shutoff dust, improve deduster efficiency of dust collection, install air duct additional in pressure air duct front end.Air duct can change into the rotary airflow of pushing ahead along lane wall by distinguished and admirable for the axis of press-in, changes air velocity distribution, stops that dust is to external diffusion, is beneficial to deduster and dust is sucked process.
Air outlet generally reduces by existing air duct, and barrel leaves some apertures, and utilize air outlet to reduce produced resistance and make distinguished and admirablely to flow out from the side, such front end air outlet is distinguished and admirable very little, can reduce front disturbance, reaches certain effect.For convenience of transport, install and use, the materials such as the flexible air duct fabric of the many employings of existing air duct, are arranged in the aperture of barrel while weakening air duct structural strength, cannot provide larger and distinguished and admirablely to flow out from the side, decrease air supply of working face virtually.Simultaneously, when combining other procedures of pick face, as supporting, upkeep operation etc., there is a lot of operating personnel in front, now the front end exit air quantity of air duct can not meet the needs of front personnel, side air-out also cannot arrive and meet head on, and cannot provide enough fresh distinguished and admirable supply of breathing and cooling etc. for operating personnel.
Utility model content
The utility model is not enough for prior art, provide a kind of structure simple, easy to operate, be easy to process safeguard, durable, the safe and reliable adjustable air duct combining pick flour dirt for preventing and treating mine.
A kind of adjustable air duct combining pick face for mine, described adjustable air duct comprises cylindrical shell, described cylindrical shell two ends are respectively equipped with cylindrical shell air intake and cylindrical shell air outlet, the annular ventilating duct described cylindrical shell side barrel being also provided with barrel air outlet and being connected with described barrel air outlet, described cylindrical shell air outlet is provided with air volume control ring and is located in the regulation and control rope on described air volume control ring;
Further, described annular ventilating duct cross section is 1/4 circular, and paste described cylinder body outer wall inside described annular ventilating duct, the radian of described barrel air outlet around barrel direction is less than 1/4 π;
Further, described annular ventilating duct is side air outlet in contrast to the side of described barrel air outlet, and described side air outlet is rectangle;
Further, described adjustable air duct also comprises bracing frame and two hooks, and described annular ventilating duct is connected with bracing frame by two hooks, and support frame as described above is that 3-5mm reinforcement welding is formed by radius;
Further, described air volume control ring is 8-12;
Further, described cylindrical shell is made up of air duct fabric.
The beneficial effects of the utility model are, a kind of adjustable air duct combining pick flour dirt for preventing and treating mine, described air duct can change into the rotary airflow of pushing ahead along lane wall by distinguished and admirable for the axis of press-in, change air velocity distribution, stop that dust is to external diffusion, be beneficial to deduster and dust is sucked process.During development machine excavation operation, air outlet is tightened by the rope in actual air volume regulation and control ring, reduce front end air outlet bore to reduce front end air output, make distinguished and admirablely to be flowed out by side air outlet through annular ventilating duct from air duct barrel air outlet according to actual needs, play the effect of shutoff work plane dust; When carrying out other operations, unclamp air outlet place, front end rope, air outlet all decontroled, distinguished and admirable under effect of inertia the overwhelming majority flow out from front end, meet forward operation personnel needs, improved by above method and combine the dust-laying effect that pick face length presses short odd test ventilation dust falling system, improve working environment at coal mines, this apparatus structure is simple, easy for installation, be easy to Operation and maintenance change, safe and reliable to operation, there is practicality widely.
