Mine vertical magnetic levitation blower device

Abstract

The invention relates to a mine vertical magnetic levitation blower device. The mine vertical magnetic levitation blower device comprises an outer barrel, an air inlet, an air outlet, a bracket, a circular ring, a rubber ring, a first magnet ring, a second magnet, and a third magnet, wherein the air inlet is vertically formed in the top of an inner cavity of the outer barrel, the air outlet is vertically formed in the bottom of the inner cavity of the outer barrel, the bracket is arranged on the upper part of the outer barrel on the horizontal surface and in a herringbone shape and is locatedbelow the air inlet, the circular ring is vertically arranged at the center of the bracket, the rubber ring is arranged on the inner side wall of the circular ring, the first magnet ring is arranged on the inner side wall of the rubber ring, the second magnet is arranged above the first magnet ring and mutually exclusive with the first magnet ring, and the third magnet is arranged under the firstmagnet ring and mutually exclusive with the first magnet ring. The mine vertical magnetic levitation blower device is reasonable in design, compact in structure, and convenient to use.

Description

technical field [0001] The invention relates to a mine vertical magnetic levitation blower device. Background technique [0002] At present, the movable blade adjustment mechanism of the axial flow fan used in the mine is mainly a parking adjustable movable blade adjustment device. The device is mainly composed of adjusting long axis, turbine box, central spur gear, bevel gear, petiole gear, petiole copper sleeve, peep window and other parts. When the working condition of the fan needs to be adjusted, the fan must be stopped first, and then the long axis of the adjustment is used to extend into the inside of the casing and align with the adjustment port of the turbine box. By adjusting the turbine box, the worm drives the bevel gear, and the bevel gear drives the leaf handle gear. Thereby, the adjustment of the rotor blade angle is realized. [0003] The adjustment device has the following defects during production and use: [0004] 1. The synchronization problem of movin...

AI Technical Summary

Problems solved by technology

Therefore, in order to ensure the synchronization of the angle adjustment of the moving blades, there are extremely high precision requirements for the bevel gears in the fan production process, so it is inevitable that some moving blades will have poor synchronization

[0006] 2. The rotor blade angle can only be adjusted after parking

[0007] When the device adjusts the rotor blades, the long axis of adjustment must be extended into the casing and aligned with the turbine box adjustment port on the impeller housing, and the angle of the rotor blades cannot be adjusted when the fan is running.

[0008] 3. Difficulty adjusting

[0009] For mine ventilators, the blade type is generally large flow and low pressure, so the blades of this series of fans are generally long, which makes it difficult to align the adjustment port of the turbine box with the long adjustment axis of the device.

[0010] 4. Angle adjustment accuracy is poor

Therefore, the angle adjustment accuracy is poor

[0012] 5. Must be adjusted on site

[0013] Since the device is purely mechanical, remote control is not possible

[0014] CN201220121548.8 Although the hydraulic movable blade adjustment device for mine fans provides a fan solution, it still cannot solve the defects of existing fans
