Abstract
The invention discloses a mine counter-rotating type local ventilator. The mine counter-rotating type local ventilator comprises a ventilator shell which is composed of an inner shell and an outer shell. A V-shaped support is arranged between the inner shell and the outer shell. The part between the inner shell and the outer shell is filled with a foamed aluminum material. The mine counter-rotating type local ventilator further comprises a current collector, a pre-muffler, a first-level explosive-proof motor, a second-level explosive-proof motor and a diffuser. The first-level explosive-proof motor and the second-level explosive-proof motor are respectively fixed into a motor fixing cylinder which is fixedly connected with the interior of the ventilator shell. The current collector is installed at the front end of the ventilator shell, the back end of the current collector is connected with the front section of a front silencing cylinder, and the back end of the front silencing cylinder is connected with the front end of the first-level explosive-proof motor. The mine counter-rotating type local ventilator further comprises the diffuser which is connected with the back end of the second-level explosive-proof motor. The mine counter-rotating type local ventilator solves the problems that an existing mine local ventilator is poor in noise reduction effect and high in energy consumption.
Description
Technical field
The invention belongs to Mine Ventilator field, relate in particular to a kind of low mining counter rotating formula booster of Wind Volume, low noise and power consumption that is applicable to down-hole mining working surface.
Background technique
Quo of local Fan for Mine is the indispensable safety installation of colliery underground ventilating, and use amount is large and wide, and the impact of its noise has not only caused the serious waste of the energy, has affected workman's physical and mental health, and very easily causes the generation of security incident.The booster of a large amount of use of mine is all to increase by front and back the effect that import silencing apparatus reaches noise reduction, but manufacture cost is also higher simultaneously, and noise eradicating efficacy is poor.And the size of required airflow can not be braked adjusting, exist the power of booster large, and the little disadvantage of required airflow has expended a large amount of electric energy.
Summary of the invention
The present invention is in order to solve the shortcoming that existing quo of local Fan for Mine noise reduction is poor, energy consumption is high, and a kind of mine counter-rotary local fan is provided.
To achieve these goals, technological scheme of the present invention is: a kind of mine counter-rotary local fan, comprise casing, casing is comprised of inner casing and shell, between inner casing and shell, being provided with V-type supports, inner casing, filled and process aluminium material between shell, also comprise the slip ring of installing successively, premuffler, I level explosion separation motor, II level explosion separation motor, diffuser, described I level explosion separation motor and II level explosion separation motor are separately fixed in motor stationary magazine creel, motor stationary magazine creel is fixedly connected with casing inside, casing front end is provided with slip ring, slip ring rear end is connected with front silencing pot leading portion, front silencing pot rear end is connected with I level explosion separation motor front end, also comprise a diffuser, described diffuser is connected with II level explosion separation motor rear end.
On described shell, be provided with sound attenuation hole.
Described slip ring and diffuser inside are equipped with respectively quieter material.
Described inner casing is the tubular structure with smooth outer surface.
Described I level explosion separation motor and II level explosion separation motor are frequency control of motor speed threephase asynchronous machine.
Mining counter rotating formula booster of the present invention has advantages of that aeroperformance is good, noise is low, it is little to consume energy, and easy to use, and the safety reliability in colliery is improved, and has guaranteed the safety in production in colliery.
