Description
Technical field
This utility model relates to a kind of mine ventilator, is specifically related to a kind of mining main fan of short axle.
Background technology
At present, on market, mine ventilator is that due to the construction features to rotation main fan, motor bearings can not bear the fan that weight is big, motor radiating weak effect to rotation main fan (such as Fig. 1), it is impossible to use in the tunnel of adverse circumstances again..Progress along with technology; blade angle-adjustable fan is succeeded in developing by our company; its core technology is axial-flow fan blade synchronous regulation mechanism; obtain the Chinese patent (patent No.: CN201220146486.6; patent name: mine axial flow main fan shuts down movable vane synchronous regulation mechanism); but this high efficiency fan weight is big, and motor bearings holds can't stand fan weight, it is impossible to directly using on rotation main fan.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art exactly, and provides a kind of mining main fan of short axle.
The technical solution adopted in the utility model is to achieve these goals: a kind of mining main fan of short axle, including current collector, shell, inner shell, blade angle-adjustable fan, short axle, short axle bearing, brake gear, motor, diffusion deafener, it is characterized in that: current collector is connected with shell, shell is built with inner shell, blade angle-adjustable fan, inner shell is built with short axle, short axle bearing, brake gear, motor, blade angle-adjustable fan is connected with short axle, short axle bearing is had on short axle, brake gear, short axle is connected with motor, ventilation shaft is had between inner shell and shell, shell is connected with diffusion deafener, air vent is had on diffusion deafener inner core.
The one mining main fan of short axle in accordance with the above, it is characterised in that: it is connected on the ventilation shaft between described inner shell and shell and has aerator.
Compared with prior art, the beneficial effects of the utility model are: fan efficiency is high, energy-conservation, noise is little, fan blade energy integral angle adjustment, thus adjusts blast, air quantity, can invert opposite direction air-supply；Motor is in forced ventilation heat dissipation environment, and this utility model can use outside tunnel, also can use in the tunnel of adverse circumstances again.

Detailed description of the invention
Accompanying drawing 1 is the prior art structural representation to rotation main fan, rotation main fan is included, and current collector 1, shell 2, one-level motor 13, one-level fan 14, light breeze fan 15, two grades of motors 16, diffusion deafener 9, to rotation main fan in order to improve blast, use the two-stage fan can motor, shortcoming is: noise is big, fan blade can not integral angle adjustment, motor bearings can not bear the fan that weight is big.Further, since the construction features to rotation main fan, motor radiating weak effect.
Embodiment 1
nullAccompanying drawing 2 is the structural representation of the short axle of this utility model mining main fan embodiment 1，The short axle of this utility model is mining main fan，Including current collector 1、Shell 2、Blade angle-adjustable fan 3、Inner shell 4、Short axle 5、Short axle bearing 6、Brake gear 7、Motor 8、Diffusion deafener 9，Current collector 1 is connected with shell 2，Shell 2 is built with inner shell 4、The core technology of blade angle-adjustable fan 3(blade angle-adjustable fan is axial-flow fan blade synchronous regulation mechanism，Refer to Chinese patent: mine axial flow main fan shuts down movable vane synchronous regulation mechanism，The patent No.: CN201220146486.6)，Inner shell 4 is built with short axle 5、Short axle bearing 6、Brake gear 7、Motor 8，Blade angle-adjustable fan 3 is connected with short axle 5，Short axle bearing 6 is had on short axle 5、Brake gear 7，Short axle 5 is connected with motor 8，Ventilation shaft 10 is had between inner shell 4 and shell 2，Shell 2 is connected with diffusion deafener 9，Air vent 12 is had on diffusion deafener inner core 11.
Embodiment 2
Accompanying drawing 3 is the structural representation of the short axle of this utility model mining main fan embodiment 2, the mining main fan of short axle in accordance with the above, it is connected on ventilation shaft 10 between described inner shell 4 and shell 2 and has aerator 13, motor and bearing are carried out forced ventilation heat radiation.Owing to vent air is cleaning ambient air, therefore, this utility model can use in the tunnel of adverse circumstances.
Compared with prior art, this utility model fan efficiency is high, energy-conservation, noise is little, a fan blade integral angle adjustment of energy, can invert opposite direction air-supply, and motor is in forced ventilation heat dissipation environment, can use in the tunnel under inferior environment.
Overall dimensions can with to rotation main fan do just as, therefore can replace to rotation main fan, other auxiliary equipment are constant.
