Abstract

The utility model discloses a high-efficiency energy-saving ventilating fan which comprises a casing, and an air inlet and an air outlet are arranged on the casing. A motor of the ventilating fan is arranged in the casing, a blade is installed on an output shaft of the motor through a wheel hub, the periphery of the motor is provided with a sealed inner cylinder, the inner cylinder is divided into a cold water cavity and a cold air cavity, the motor is arranged in the cold water cavity and is sealed by a cover casing, the other end of the output shaft in the motor is provided with a cooling blade which is communicated with the cold air cavity, the cold water cavity and the cold air cavity are respectively provided with a cooling water outlet, a cooling water inlet, a cooling air outlet and a cooling air inlet. The ventilating fan not only can convey high temperature air current such as boiler flue gas, etc., but also can be applied for non-high temperature occasions such as tunnel ventilation, etc.

Description

Energy-efficient ventilator
The utility model relates to a kind of ventilator.
In the prior art, the flue gas of boiler need be discharged by the ventilator air draught, because the working environment of boiler room is relatively poor, the temperature height, dust is big, and flue gas is again a high temperature gas flow, so to the requirement of ventilator also than higher, present ventilator is separated motor and blower fan, and motor drives blower fan by driving mechanism, is damaged to avoid motor to be subjected to the influence of high-temperature flue gas, but the volume of this type of ventilator is big, noise big, vibration is big, power consumption is big, and therefore, the conveying of high temperature gas flow is still a great problem so far.
The purpose of this utility model is: a kind of energy-efficient ventilator is provided, and it organically is combined into one blower fan and motor, not only can carry high temperature gas flow, more can use in other non high temperature occasion.
The technical solution of the utility model is: a kind of energy-efficient ventilator, comprise casing, casing is provided with intake grill and exhaust outlet, and the motor of this ventilator is arranged in the casing, fan blade is installed in by wheel hub on the output shaft of motor, and the periphery of described motor is provided with the inner core of sealing.
The further technological scheme of the utility model is: a kind of energy-efficient ventilator, comprise casing, casing is provided with intake grill and exhaust outlet, and the motor of this ventilator is arranged in the casing, fan blade is installed in by wheel hub on the output shaft of motor, and the periphery of described motor is provided with the inner core of sealing; Described inner core is divided into cold water cavity and two chambeies, cold wind chamber, and motor is positioned at cold water cavity and seals with case, and the other end of the output shaft of motor is provided with cooling fan blade and communicates with the cold wind chamber, and cold water cavity and cold wind chamber are respectively equipped with cooling water outlet and inlet and cooling air is imported and exported; Be filled with thermal-protective material in the wall of described inner core.
The utility model has the advantages that:
1. the utility model organically is combined into one blower fan and motor, and fan blade is directly installed on the motor output shaft, and noise is little during work, and energy consumption is low, and is simple in structure, has save a whole set of driving mechanism.
2. the utility model places motor in the inner core, and is provided with cold water cavity and cold wind chamber, has successfully solved the heat dissipation problem of ventilator motor when carrying high temperature gas flow, can guarantee that motor safety normally uses.
3. be filled with thermal-protective material in the inner tube wall of the present utility model, can guarantee that the heat of high temperature gas flow in the air channel does not pass to the interior motor of inner core.
4. the utility model not only can be carried high temperature gas flows such as boiler smoke, more can be applied to non high temperature occasions such as tunnel ventilation.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1. casing; 2. intake grill; 3. exhaust outlet; 4. motor; 5. fan blade; 6. wheel hub; 7. output shaft; 8. inner core; 9. case; 10. cold water cavity; 11. cold wind chamber; 12. cooling fan blade; 13. cooling water outlet and inlet; 14. cooling air is imported and exported; 15. thermal-protective material.
