Description

Mine vertical magnetic suspension blower device

Technical Field

The utility model relates to a vertical magnetic suspension air-blower device of mine.

Background

At present, a movable blade adjusting mechanism of an axial flow fan for a mine is mainly a parking adjustable movable blade adjusting device. The device mainly comprises a regulating long shaft, a turbine box, a central straight gear, a bevel gear, a petiole copper sleeve, a peep window and other parts. When the working condition of the fan needs to be adjusted, the fan must be stopped firstly, then the adjusting long shaft extends into the shell to be aligned with the adjusting port of the turbine box, the bevel gear is driven by the worm through adjusting the turbine box, and the blade shank gear is driven by the bevel gear, so that the adjustment of the angle of the movable blade is realized.

The adjusting device has the following defects in the production and use processes:

1. the problem of blade synchronism caused by machining accuracy.

The device mainly depends on a large umbrella size to drive 16 or 20 small petiole bevel gears to realize movable blade adjustment. Therefore, in order to ensure the synchronism of the angle adjustment of the movable blades, the bevel gear of the petiole has extremely high precision requirement in the production process of the fan, so that the situation that the synchronism of a plurality of movable blades is poor is inevitable.

2. The adjustment of the angle of the movable blade can be carried out after the vehicle is stopped.

When the movable vane angle adjusting device is used for adjusting the movable vane, the adjusting long shaft is required to extend into the shell to be aligned to the turbine box adjusting port on the impeller shell, and the movable vane angle cannot be adjusted when the fan runs.

3. Difficulty in adjustment

For mine ventilators, the general principle is that the blades are large in flow rate and small in pressure, so that the fan blades of the series are generally too long, the long adjusting shaft of the device is too long to be aligned with the adjusting port of the turbine box,

4. poor angle adjustment precision

The movable blade angle adjustment feedback of the device needs to be observed from a peephole in a shell, and the current angle of the movable blade is judged by taking the tail part of the movable blade as a pointer through a scale mark. The angle adjustment accuracy is poor.

5. Must be adjusted on site

Because the device is a pure mechanical structure, the remote control cannot be realized.

Although the CN201220121548.8 hydraulic pressure movable vane adjusting device for mine fan provides a fan scheme, still can not solve the defect of current fan.
