Abstract
The utility model provides a contra-rotating axial-flow type partial ventilating machine with built-in ventilating pipes, which is mainly used for underground operation of a coal mine in an explosive gas atmosphere and is characterized in that the ventilating pipes are respectively arranged on a silencing column barrel body and a conical barrel body. When in use, air flows through the ventilating pipes to carry out radiation on a motor and a bearing thereof, so as to lower the temperature, thereby achieving the purpose of protecting normal running of the motor and the bearing. The contra-rotating axial-flow type partial ventilating machine adopts simple design structure and needs low production cost; in addition, the normal running of the ventilating machine can be well ensured to reduce safety accidents of the coal mine.
Description
Technical field
The utility model is a kind ofly to be mainly used in metal mine, chemical mine, tunnel and other need the place of ventilation, the opposite-rotary axial flow type booster with built-in ventilation duct that uses during by the coal mine operation of explosive gas atmosphere in particular for tool.
Background technique
At present under coal mine, use to the axial flow rotary booster, be by the motor in the ventilator cylindrical shell, the impeller blade rotation is carried out ventilation to the down-hole.But it does not have aeration structure to axial flow rotary booster fuselage interior, causes in motor operation course, and the tail bearing of motor is because the heating easily that runs up, and heat is difficult for distributing, motor burns out when serious, and the blower fan stall directly affects the safety in production of coal mine.
Summary of the invention
Goal of the invention of the present utility model will provide a kind of opposite-rotary axial flow type booster with built-in ventilation duct exactly, can carry out radiating and cooling to ventilator inside, prevents that motor and bearing Yin Wendu thereof are too high and the accident of burning takes place.
Technical solution of the present utility model is such: a kind of opposite-rotary axial flow type booster with built-in ventilation duct, form by ventilator cylindrical shell, motor, impeller, noise elimination column casing body, conic tube etc., a ventilation duct all is installed on it is characterized in that eliminating the noise column casing body and the conic tube.During use, air flows by ventilation duct, and motor and bearing thereof are dispelled the heat, and reduces temperature, reaches the purpose that protection motor and bearing run well.The use the beneficial effects of the utility model are: project organization is simple, and cost of production is lower, can well guarantee the normal operation of opposite-rotary axial flow type booster, reduces the generation of mine safety accident.
Description of drawings
Accompanying drawing 1 is a generalized section of the present utility model.
Embodiment
Among Fig. 1, motor 12, impeller 10, noise elimination column casing body 3, conic tube 9 are installed in the ventilator cylindrical shell 1 of opposite-rotary axial flow type booster.On noise elimination column casing body 3, conic tube 9, all fixedly mounting a ventilation duct 4.The rotating shaft 5 of ventilation duct 4 and motor 12 is on same axis.Ventilation duct 4 can be made of metal or nonmetal tubing, is fixedly mounted on noise elimination column casing body 3 and the conic tube 9 with welding or bolt connecting mode.
Claims (2)
1. opposite-rotary axial flow type booster with built-in ventilation duct, form by ventilator cylindrical shell (1), motor (12), impeller (10), noise elimination column casing body (3), conic tube (9) etc., on it is characterized in that eliminating the noise column casing body (3) and the conic tube (9) ventilation duct (4) is installed all.
