Abstract
The utility model discloses a high temperature resistant axial flow fan, which comprises a fan outer cylinder, a fan inner cylinder, a motor and a fan blade, wherein the fan blade is arranged on a motor shaft; the high temperature resistant axial flow fan is characterized in that the motor is arranged in the fan outer cylinder; the fan inner cylinder is coated on a motor body; an air exhaust blade is arranged on a tail shaft of the motor; an air exhaust pipe led from the fan outer cylinder is arranged on the fan inner cylinder; an air inlet pipe corresponding to the air exhaust blade is arranged on the fan inner cylinder; a hollow sandwich is arranged on the cylinder wall of the fan inner cylinder; and a heat insulating material is filled in the sandwich. As the heat insulating material is adopted, the motor in the inner cylinder can be prevented from influence of environment circulating heat; and as a separable inner cylinder structure is adopted, the working intensity for maintenance and replacement of the motor is reduced and the service life of the motor is prolonged. The high temperature resistant axial flow fan disclosed by the utility model has the advantages that the structure is simple, the cooling effect is obvious and the service life of the fan is prolonged.

Technical field
The utility model relates to axial-flow blower, especially a kind of high-temperature resistant axial-flow fan.
Background technique
Axial-flow blower is again booster, industrial and mining enterprise's a kind of blower fans commonly used, what be different from general blower fan is, all in a cylinder, profile is exactly a tubular for its motor and fan blade, is used for local ventilation, easy for installation, the ventilation successful, safety, the cylinder of can giving a dinner for a visitor from afar is kept watch and is delivered to the zone of appointment.
Because the Environmental Conditions of axial-flow blower is more abominable, in the higher environment of ambient temperature, the blower fan inner core does not have heat insulation measures, in long-term use, produces easily thermal cycle, causes motor temperature constantly to raise, and motor is easy to break down.
The model utility content
The purpose of this utility model provides a kind of high-temperature resistant axial-flow fan that is applicable to workroom in high temperature.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of high-temperature resistant axial-flow fan, comprise: blower fan urceolus, blower fan inner core, motor, fan blade, described fan blade is located on the motor shaft, it is characterized in that: motor is located in the blower fan urceolus, and the blower fan inner core coats the motor fuselage, is provided with the fan blade of bleeding at the afterbody axle of motor, be provided with the outlet pipe of being introduced by the blower fan urceolus at the blower fan inner core, be provided with the suction tude corresponding with the fan blade of bleeding at the blower fan inner core; The barrel of blower fan inner core is provided with hollow sandwich, the inner filling with insulation material of its interlayer.
Preferably, described suction tude is made of admission line, adpting flange, and admission line is located at the adpting flange axle center, and this admission line runs through the blower fan urceolus and is communicated with outside.
Preferably, described outlet pipe runs through the blower fan inner core from blower fan inner core inside, the blower fan urceolus is communicated with outside.
Preferably, described suction tude is fixedly connected with the blower fan inner core by screw.
Preferably, described thermal-protective material is that high temperature is cotton.
After the utility model adopts said structure, owing to adopted cold wind circulating cooling form, outside parcel thermal insulation material, guaranteed that the motor in the inner core can not be subject to the impact of environment circulated heat; Adopt detachable inner tube structure, lowered the working strength of motor when maintenance is changed, the working life of having improved motor.The utility model is simple in structure, and cooling-down effect is obvious, has improved the working life of blower fan.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
