Double impeller ventilating apparatus with rubber pipe wind pipe

Abstract

The invention aims to provide a double-impeller ventilating device with hose wind cylinders, which has the advantages of low windage resistance, low air leakage, low cost and high ventilating efficiency. The double-impeller ventilating device comprises a shell and a motor arranged in the shell, wherein both ends of a shaft of the motor are provided with isodromic fan impellers which can relatively rotate, and both ends of the shell are respectively provided with the hose wind cylinders. When the double-impeller ventilating device operates, the fan impellers are driven by the motor through a driving device to rotate in the shell; under the function of atmospheric pressure, outside air continuously flows into one fan impeller from a wind suction hole along a rotating shaft through the hose wind cylinders, the rotating impeller lead the flowed air to obtain energy to prompt the acceleration of the other fan impeller, and consequently, the air can be quickly exhausted into the atmosphere to increase the ventilating efficiency of a mine. The invention adopts a mechanical ventilating method with double impellers and double wind cylinders, the motor power of a fan is reduced under the condition that the wind pressure and the wind quantity of the mine are constantly maintained, and consequently, the invention can achieve the purpose of energy conservation.

Description

technical field [0001] The invention belongs to the field of mine equipment, relates to a mine ventilation equipment, in particular to a Background technique [0002] During the mine development period, long-distance individual excavation projects are often encountered. Some individual excavation distances are as long as 2-3KM. Whether the long-distance individual excavation can be successfully implemented often depends on how to effectively solve the ventilation problem of the individual working face. At present, the feasible methods roughly include the following: [0003] (1) Use local fans in series for ventilation [0004] Multiple local fans connected in series can solve the ventilation problem of long-distance excavation without high-pressure local fans. According to the layout of the local fan, it can be divided into two forms: centralized series connection and interval series connection. Due to the shortcomings of large air leakage in centralized series connection...

Problems solved by technology

[0010] In order to effectively reduce the resistance of the air duct and reduce air leakage, the common method is to use a rigid air duct, but since most of the rigid air ducts are made of iron sheets, it is very difficult to disassemble and move, and they are large in size and easy to corrode
