Abstract
The utility model relates to the technical scheme of ventilators and particularly relates to an axial flow ventilator for a bunker, wherein the axial flow ventilator for the bunker solves current problems that the axial flow ventilator for the bunker is bad in waterproof effect. The axial flow ventilator for the bunker comprises a ventilator shell (1), a motor (3) and a fan blade (5). The motor (3) and the fan blade (5) are arranged in the ventilator shell (1), an outlet shaft of the motor (3) drives the fan blade (5) to rotate, a pipe shaped wiring export (4) is arranged on the motor (3) and is connected with a conduit (2) through threads, the conduit (2) is extended outside the ventilator shell (1), the pipe shaped wiring export (4) is provided with external threads, and the conduit (2) is provided with internal threads matched with the external threads of the wiring export (4). The axial flow ventilator for the bunker is simple in structure and reasonable in design, prolongs service life and ensures safe and stable operation of production.
Description
Technical field
The utility model relates to the blower fan technical field, is specially a kind of coal bunker axial-flow blower.
Background technique
At present, the axial-flow blower that coal bunker is used comprises Blower Housing 1, motor 3, blade 5, described motor 3, blade 5 place in the Blower Housing 1 and the output shaft drive vane 5 of motor 3 is rotated, motor 3 is provided with the tubulose wiring outlet 4 with internal thread, wiring outlet 4 has been threaded and has had externally threaded penetration pipe 2, and penetration pipe 2 stretches out outside the Blower Housing 1.
During use, 5 rotations of motor 3 drive vane, since the wiring of motor 3 outlet 4 have internal thread and with have externally threaded penetration pipe 2 and directly be connected, when running into sleety weather, rainwater exports 4 places along the wiring that penetration pipe 2 flows to motor 3 easily, then flows in the motors 3 along wiring outlet 4, soaks motor coil, destroy insulation, cause motor coil to burn out.So existing coal bunker is poor with the waterproofing effect of axial-flow blower, had a strong impact on the working life of motor in the blower fan, cause coal bunker gas blower fan large size to burn out, so that gas can not in time discharge in the coal bunker, Safety of Coal Mine Production has been consisted of serious threat.
Therefore, be necessary existing coal bunker is improved with axial-flow blower, improve the waterproofing effect of axial-flow blower.
Summary of the invention
The utility model provides a kind of novel coal bunker axial-flow blower in order to solve existing coal bunker with the poor problem of waterproofing effect of axial-flow blower.
The utility model is to adopt following technological scheme to realize:
A kind of coal bunker axial-flow blower, comprise Blower Housing, motor, blade, described motor and blade place in the Blower Housing, the output shaft drive vane rotation of motor, described motor is provided with the wiring outlet of tubulose, and described wiring outlet has been threaded connection penetration pipe, and described penetration pipe stretches out outside the Blower Housing, described wiring export processing has outside thread, and described penetration pipe is processed with the internal thread that matches with the outside thread of wiring outlet.
During work, the motor driving blade rotary, when running into sleety weather, because penetration pipe adopts female thread structure, wiring outlet to adopt external thread structure, rainwater flows to outside motor along penetration pipe through its outside, avoids rainwater to flow into motor internal along penetration pipe through the wiring outlet, burns out the situation of motor, improve service life of equipment, guaranteed simultaneously the safe and stable operation of producing.
The utility model is simple in structure, reasonable in design, efficiently solves the existing coal bunker poor problem of axial-flow blower water proofing property.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1-Blower Housing, 2-penetration pipe, 3-motor, 4-wiring outlet, 5-blade.
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of coal bunker axial-flow blower, comprise Blower Housing 1, motor 3, blade 5, described motor 3 and blade 5 place in the Blower Housing 1, output shaft drive vane 5 rotations of motor 3, and described motor 3 is provided with the wiring outlet 4 of tubulose, described wiring outlet 4 has been threaded connection penetration pipe 2, described penetration pipe 2 stretches out outside the Blower Housing 1, and described wiring outlet 4 is processed with outside thread, and described penetration pipe 2 is processed with the internal thread that matches with the outside thread of wiring outlet 4.
During implementation, exporting 4 outer surface machinings in the tubulose wiring of motor 3 has outside thread, and penetration pipe 2 is formed by the pipeline welding of different-diameter, is processed with the internal thread that matches with outside thread in the wiring outlet 4 on the motor 3 in large diameter pipeline.
During specific works, 5 rotations of motor 3 drive vane, when running into sleety weather, because penetration pipe 2 adopts female thread structure, wiring outlet 4 to adopt external thread structure, rainwater flows to motor 3 outsides along penetration pipe 2 through its outside, avoid rainwater to flow into motor 3 inside along penetration pipe 2 through wiring outlet 4, burns out the situation of motor, improve service life of equipment, guaranteed simultaneously the safe and stable operation of producing.
