Abstract
The utility model discloses a heat-resistant blower, comprising a frame. The frame is provided with a main shaft, an impeller, a spiral casing and a wind cooling device. The impeller is arranged at the head end of the main shaft, and the spiral casing is covered outside the impeller; the wind cooling device is arranged on the main shaft; and the tail end of the main shaft is connected with a motor by a transmission device. The main shaft is a hollow shaft, and the tail of the shaft is provided with a cold air inlet; the hollow shaft is provided with at least one air outlet hole, and the position of the air outlet hole is arranged in a position where the wind cooling device is positioned. The wind cooling device is formed by a plurality of radiating sheets which are connected on the hollow shaft. The heat-resistant blower has good radiation effect and simple structure.
Description
Technology neck city
The utility model relates to industrial heat treatment field, especially a kind of heat resisting exhauster.
Background technique
The blower fan producer of present many production high-temperature blowers at high temperature can not take water-cooling to high-temperature blower and take air-cooled loosing.Because wind-cooling heat dissipating can only carry out the part heat radiation, axle and bearing that high temperature is used can not satisfy its self conduction heat of loosing, and in the working life of reducing axle and bearing, the operating cost of blower fan are increased.
Summary of the invention
What the utility model solved is that existing Wind-cooling type high-temperature blower needs often to change axle and bearing, causes the high problem of maintenance operating cost.Concrete technological scheme is as follows:
A kind of heat resisting exhauster comprises frame, and frame is provided with main shaft, impeller, spiral case and air cooling equipment, and impeller is located at the main shaft head end, and impeller outer is covered with spiral case; Air cooling equipment is located on the main shaft; The tail end of main shaft connects motor by transmission device.Described main shaft is a hollow shaft, and the tail end of axle is provided with into cold wind mouth; Be provided with at least 1 air outlet hole on hollow shaft, the position of this air outlet hole is at the air cooling equipment place.
The quantity of described air outlet hole can be determined according to the sectional area of the hollow cavity of hollow shaft and the air mass flow of air cooling equipment, can select 2 or more.Described air cooling equipment is to be made of a plurality of radiating fin that are fixed on the hollow shaft.There is torsional angle in each cross section of described radiating fin, and a plurality of radiating fin are fixed on and constitute small impeller on the hollow shaft.The transmission device that the tail end of described hollow shaft connects motor is a belt, and the tail end of hollow shaft is provided with belt pulley, and the rotor of motor also is provided with belt pulley.
In the time of heat resisting exhauster work; the air cooling equipment of itself is also rotating; circulate driving self-heat irradiation device again in wind-cooling heat dissipating, can effectively leave and conduct heat to axle and bearing by high temperature, protection axle and associated components are at high temperature worked better.In the time of heat resisting exhauster work, the air cooling equipment on the hollow shaft is also rotating along the axle center, because hollow shaft has air outlet hole at the air cooling equipment place, the generation negative pressuren zone drives the cool air that is entered by shaft tail end and circulates, and has reduced being heated of axle and bearing.
Compared with prior art, the beneficial effects of the utility model are good heat dissipation effect, and are simple in structure.

Embodiment
Further specify the utility model below in conjunction with Fig. 1,2.
A kind of heat resisting exhauster comprises frame 5, and frame is provided with main shaft, impeller 6, spiral case 7 and air cooling equipment 2, and impeller 6 is located at the main shaft head end, and impeller 6 is covered with spiral case 7; Air cooling equipment 2 is located on the main shaft; The tail end of main shaft connects motor by transmission device 8.Described main shaft is a hollow shaft 1, and the tail of axle is provided with into cold wind mouth 4; Be provided with 2 air outlet holes 3 on hollow shaft 1, the position of this air outlet hole is at air cooling equipment 2 places.Described air cooling equipment is to be made of a plurality of radiating fin that are fixed on the hollow shaft.There is torsional angle in each cross section of described radiating fin, and a plurality of radiating fin are fixed on and constitute small impeller on the hollow shaft.The transmission device that the tail end of described hollow shaft connects motor is a belt, and the tail end of hollow shaft is provided with belt pulley, and the rotor of motor also is provided with belt pulley.The transmission device 8 that the tail end of described hollow shaft 1 connects motor is belts, and the tail end of hollow shaft is provided with belt pulley, and the rotor of motor also is provided with belt pulley.
During heat resisting exhauster work, impeller and sink are rotated work, and hollow spindle 1 has air outlet hole 3 at air cooling equipment 2 places, produces relative negative pressuren zone herein, drive is entered hollow shaft 1 and by air outlet hole 3 discharges, is finished the cold wind circulation by the cool air that hollow spindle opens wide atmosphere end.The heat part that high temperature conducts to axle and bearing is left by sink, and a part is left by the circuit cool air, has significantly reduced the heated time of axle and bearing, thereby has protected axle and the working condition of bearing under high-temperature condition.Prolong the working life of axle and bearing effectively, reduced maintenance cost.
