Abstract
A short-shaft mining main fan comprises a current collector, an outer shell, an inner shell, a fan body with a blade angle adjusting function, a short shaft, a short shaft bearing, a braking device, a motor and a diffusion silencer. The short-shaft mining main fan is characterized in that the current collector is connected with the outer shell; the inner shell and the fan body with the blade angle adjusting function are arranged in the outer shell; the short shaft, the short shaft bearing, the braking device and the motor are arranged in the inner shell; the fan body with the blade angle adjusting function is connected with the short shaft, and the short shaft is provided with the short shaft bearing and the braking device and connected with the motor; a vent pipeline is arranged between the inner shell and the outer shell, the outer shell is connected with the diffusion silencer, and a vent hole is formed in an inner barrel of the diffusion silencer; and the vent pipeline between the inner shell and the outer shell is connected with an air blower. The short-shaft mining main fan has the beneficial effects that the efficiency of the fan is high, energy is saved, noise is low, the angle of fan blades can be overall adjusted, and therefore the air pressure and the air volume are adjusted, and reverse rotation can be carried out to supply air in the reverse direction; and the motor is located in a forced ventilation and heat dissipation environment, and the short-shaft mining main fan can be used outside an underground tunnel and can also be used in an underground tunnel in a severer environment.
Description
Technical field
The present invention relates to a kind of mine ventilator, be 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 the present invention overcomes the deficiencies in the prior art exactly, and provides a kind of mining main fan of short axle.
The technical solution used in the present invention 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 invention has the beneficial effects as follows: fan efficiency is high, energy-conservation, noise is little, fan blade energy integral angle adjustment, thus adjusts blast, air quantity, opposite direction air-supply can be inverted；Motor is in forced ventilation heat dissipation environment, and the present invention can use outside tunnel, also can use in the tunnel of adverse circumstances again.
