Abstract
The utility model relates to mining equipment, in particular to an air volume regulator of a contra-rotating fan which solves the problems of inconvenient operation, difficult air volume control, potential safety hazard and the like of the existing air regulator, and comprises a barrel body, wherein the barrel body is provided with an air regulation outlet and hinged with an air-out cover plate; a semicircular fan-shaped fan blade which is integrated with the air-out cover plate is arranged in the barrel body; the upper part of the barrel body is provided with a driving member connected with the air-out cover plate; the driving member comprises a supporting frame and a lead screw nut mechanism set up on the supporting frame; a front end of the lead screw is connected with the air-out cover plate, and a back end thereof is provided with a turnplate and a crank. The air volume regulator of the contra-rotating fan has convenient operation and flexible use, and leads the fan blade to move up and down by adjusting trips of the lead screw, thus achieving the aim of air volume regulation and ensuring the safety problem when the fan exhausts gas. The device saves time and effort, has flexible operation, and can adjust and control the air volume arbitrarily, achieve the desired effect, reduce the labor intensity of workers, and ensure the safety of the mine and operating personnel.
Description
Technical field
The utility model relates to a kind of mining equipment, is specially a kind of counter-rotating fan blast regulator.
Background technique
At present, the colliery in process of production, driving face when discharging digging laneway gas, need be taken the air duct interface apart having a power failure, usually needing firedamp drainage after the blowing-out in the past, regulated air quantity by regulating the size that changes the involutory gap of air duct interface.Adopt the method and device in actual production, to have following defective: the one, disconnect the air duct inconvenient operation, and straight the hanging of air duct is difficult for also guaranteeing; The 2nd, air quantity control is unstable, and there is suddenly big or suddenly small phenomenon in the firedamp drainage air quantity, has great potential safety hazard.
Summary of the invention
The louver that the utility model adopts when solving existing firedamp drainage exist operation inconvenience, air quantity wayward, have problem such as potential safety hazard, a kind of counter-rotating fan blast regulator is provided.
The utility model is to adopt following technological scheme to realize: the counter-rotating fan blast regulator, comprise the cylindrical shell that two ends are connected with fan outlet, air duct respectively, innovative point of the present utility model is to be positioned to have air quantity on the barrel of cylindrical shell inlet side and regulate outlet, be hinged with on the cylindrical shell with air quantity and regulate the air-out cover plate that outlet cooperatively interacts, be provided with the semicircular sector fan blade that fuses with the air-out cover plate in the cylindrical shell; Cylindrical shell top is equipped with and is connected and is used to drive the up and down driving component of air-out cover plate with the air-out cover plate.Adopt structural design of the present utility model, between fan outlet and air duct, set up this blast regulator, by the folding up and down of driving component control air-out cover plate, make air quantity little when big when regulating the air quantity of outlet, then the feasible semicircular sector fan blade that is connected as a single entity with the air-out cover plate freely rotates in simplified, when the air-out cover plate moves upward, the semicircular sector fan blade moves downward, and the intake grill that forms between the cylindrical shell diminishes, the air output of air quantity adjusting this moment mouth is bigger, and reduces by the air quantity of cylindrical shell; When the air-out cover plate moved downward, the semicircular sector fan blade moved upward, and the intake grill that forms between cylindrical shell change greatly, and the air output of air quantity adjusting this moment mouth is less, and passed through the air quantity increase of cylindrical shell, thereby had reached the purpose of regulating air quantity.
Driving component described in the utility model can adopt the multiple known structural type of mechanical field to realize, the preferred driving component of the utility model comprises and is fixed in the supporting frame on the cylindrical shell and is erected at screw-nut body on the supporting frame, the leading screw front end is connected by fixing pin with the air-out cover plate, the rear end is equipped with rotating disk and crank, artificial by the crank rotary turnplate, make and the screw-nut body motion reach the purpose of controlling the folding of air-out cover plate.
Compared with prior art, the utility model is easy and simple to handle, use flexibly, by regulating the screw mandrel stroke fan blade is moved up and down, thereby reach the purpose of regulating air quantity, safety problem when having guaranteed the blower fan gas-removing, use this device time saving and energy saving, flexible operation, but regulated at will and control air quantity size have reached the Expected Results of this device, have alleviated worker's labor intensity, ensured mine and operating personnel's safety, for solid foundation has been laid in the safety in production in colliery, this device uses when being applicable to any highly gassy mine blower fan gas-removing, and high promotional value is arranged.
