Description
Technical field
The utility model relates to a kind of pressure wind of quantity-adjustable and shunts attached wall air duct, is applicable to mechanization driving face combination of forced and exhaust ventilation system under the coal mine, improves the efficiency of dust collection of dust pelletizing system.
Background technology
The dust of fully-mechanized digging machine driving face is bigger under the coal mine, both endangered workman's physical and mental health, production brings threat to mine safety again, therefore, usually adopting long pressure weak point to take out ventilation system administers the boring head dust, coal mine machinery driving face is at home and abroad pressed and is taken out in the mixed ventilation, normal adopt attached wall air duct distinguished and admirable to become rotation distinguished and admirable section axial, and meet head on to advance to work plane, form the air curtain of a rotation, the diffusion of control dust-contained airflow is in order to improve the dust-collecting efficiency of dust pelletizing system.Existing attached wall air duct generally all is that iron sheet is made, and outlet along the circumferential direction all is that several thousand radiuses are the aperture of 5mm, and processed complex is mobile frequent, install, storage is all cumbersome, and air-out is unreasonable.In addition, traditional attached wall air duct can not be regulated the air output of the axial and attached wall direction of air duct, restriction and the bigger reason of dedusting fan resistance owing to dedusting fan power, it is difficult frequently to improve suction, therefore, traditional attached wall air duct just can't adopt presses the method for wind shunting to improve the suction ratio, and therefore, dust-laying effect is subjected to bigger restriction.
Summary of the invention
The purpose of this utility model is that traditional attached wall air duct is improved, a kind of attached wall air duct of regulating the axial and attached wall direction of air duct air quantity is provided, this air duct processing is simple, conveniently moving, can store a large amount of flexible air ducts, avoid the frequent spreading air duct in the mobile blower fan process, and the air-out along the circumferential direction of novel air duct is reasonable.
In order to achieve the above object, the utility model provides a kind of pressure wind of quantity-adjustable to shunt attached wall air duct, comprise cylindrical shell, flexible air duct storage shelf and hook, the front end of described air duct cylindrical shell is provided with the airflow regulating switch of quantity-adjustable, cylindrical shell one side is provided with wind guide tank, wind guide tank and cylindrical shell curl arrange that wind guide tank one end is connected with barrel by the barrel air outlet, and the other end is and blows out distinguished and admirable forward less than 90 ° of angles.
Further, described cylindrical shell length is 2 ~ 5m.
The beneficial effects of the utility model are:
Technical solutions of the utility model are compared with traditional attached wall air duct, traditional attached wall air duct can not be regulated the air output of the axial and attached wall direction of air duct, can't adopt the method for pressing the wind shunting to improve the suction ratio, airflow regulating switch is made by sheet iron plate and the axis of rotation that diameter is slightly less than barrel diameter, sheet iron plate is divided into two along diametric(al), be welded on respectively on two axis of rotation, the switch of forming two quantity-adjustables, switch is divided into ten shelves, adjusts air quantity by what regulate verge board with the cylindrical shell angulation.
The novel attached wall air duct that the utility model can be regulated air output is a kind of rigidity air duct, be applicable to and adopt pressure system of ventilation under the coal mine and be equipped with foam or the driving face of spray for dust suppression system, attached wall air duct length overall 2 ~ 5m, the air duct diameter can arbitrarily change as required, by cylindrical shell, flexible air duct storage shelf, hook, wind guide tank and airflow regulating switch are formed, cylindrical shell is made by steel sheet, the wind guide tank curl is weldingly fixed on cylindrical shell wall one side, the one end is connected with barrel by the barrel air outlet, and the other end blows out distinguished and admirable generation wall attachment effect at an angle forward; Airflow regulating switch is made by sheet iron plate and the axis of rotation that diameter is slightly less than barrel diameter, sheet iron plate is divided into two along diametric(al), be welded on respectively on two axis of rotation, the switch of forming two quantity-adjustables, switch is divided into ten shelves, adjusts air quantity by what regulate verge board with the cylindrical shell angulation; Flexible air duct storage shelf is made up of three skeletons that are connected with attached wall air duct, is mainly used in storing temporary transient no flexible air duct, avoids because of the frequent movement of tunneling the blower fan that moves ahead spreading air duct frequently;

The specific embodiment
For making the purpose of this utility model, technical scheme and beneficial effect clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model provides a kind of pressure wind of quantity-adjustable to shunt attached wall air duct, the pressure wind of this quantity-adjustable is shunted attached wall air duct and is comprised air duct cylindrical shell 1, flexible air duct storage shelf 4 and link up with 2, the front end of described air duct cylindrical shell 1 is provided with the airflow regulating switch 6 of quantity-adjustable, this air duct cylindrical shell 1 length is 2 ~ 5m, air duct cylindrical shell one side is provided with wind guide tank 3, wind guide tank 3 is arranged with cylindrical shell 1 curl, wind guide tank 3 one ends are connected with barrel by barrel air outlet 5, and the other end is and blows out distinguished and admirable forward less than 90 ° of angles; When coal cutting begins, airflow regulating switch 6 in the attached wall air duct is adjusted to certain gear, make the people's formula air duct supply machine pick work of former pressure and axial distinguished and admirable distinguished and admirable two parts of rotation of changing into and wall axial along air duct distinguished and admirable, the wind that blows out from barrel air outlet 5 blows out the back blows to the tunnel with certain rotary speed perisporium and whole tunnel section through wind guide tank 3, and constantly advance to tunneling working face, sucking dust-contained airflow at deduster produces under the acting in conjunction of axial velocity, just form the zigzag shape air-flow with higher functionality, set up in the place ahead of development machine driver and to stop that dust is to the air screen of external diffusion, the dust that produces when blocking development machine work, making it to suck deduster through dust shield purifies and does not outflow, thereby improved the dust-collecting efficiency of tunneling working face, when carrying out other operations when not coal cutting, airflow regulating switch 6 in the attached wall air duct is transferred to the gear of opening fully, make the fresh distinguished and admirable people's work plane that directly advances, return to normal ventilation.The temporary transient not air duct of usefulness can be stored in above the flexible air duct storage shelf 4, discharges flexible air duct gradually along with the reach of development machine and attached wall air duct cylindrical shell 1, has avoided frequent spreading air duct, has improved drivage efficiency greatly.
The utility model protection domain is not limited to above-mentioned example, and every technology distortion of doing according to the technology of the present invention principle all falls within protection scope of the present invention.
