Abstract
A belt gearing high temperature axial flow fan relates to pipe axial flow fan with a high temperature isolating cavity, which comprises a shell, a motor and a vane wheel fixed on the shell and a drive system. Wherein, the drive system is composed of a drive shaft, a bearing, a belt and a belt pulley. The drive shaft, bearing, belt and belt pulley are arranged in the isolating cavity. Low-temperature air flows through the drive system and then the vane wheel. The utility model has the advantages that low-temperature air firstly flows through the isolating cavity arranged with the drive shaft, bearing, belt and belt pulley and then passes through the vane wheel, thus injecting the low-temperature air to cool the drive system. The motor, drive shaft, bearing, belt and belt pulley are isolated by the isolating cavity for protection. High-temperature air will not flow through the motor, drive shaft, bearing, belt and belt pulley. The belt gearing high temperature axial flow fan is suitable for exhaust fans, in particular upwards blowing roof exhaust fan, showing remarkable effect.
Description
Technical field
The utility model relates to a kind of belt transmission high-temperature axial flow fan, relate in particular to a kind of pipe axis flow fan with the high temperature separate cavities, be specially adapted to get rid of the gas of high temperature or fire-fighting smoke evacuation, for example discharging of kitchen fume or workshop machine oil or fire-fighting smoke evacuation or automobile engine tail gas laboratory or industrial high temperature waste gas etc.
Background technique
The room axial-flow blower generally is installed in pipeline or roof, is used for from indoor discharge gas, finishes the ventilation requirement of designing institute regulation.
Because the motor and the driving component of conventional axial-flow blower are directly exposed within the high temperature gas flow, in industry and commercial in service, there is certain use obstacle in the continuous operation in the time of can't guaranteeing high temperature discharge.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of increasing exhaust gas flow temperature scope, long new structure belt transmission high-temperature axial flow fan of life-span.
The scheme that the utility model solves the problems of the technologies described above employing is: the belt transmission high-temperature axial flow fan; comprise casing, be fixed on motor, impeller on the casing and the transmission system that constitutes by transmission shaft, bearing, belt, belt pulley; wherein; described transmission shaft, bearing, belt, belt pulley are positioned at the insulation blocking chamber, the low-temperature airflow impeller of flowing through again after the transmission system of flowing through.Described transmission shaft, bearing, belt, belt pulley carry out insulation blocking by isolated chambers and high temperature media air-flow; and according to hydromechanical injection principle; with the normal low-temperature airflow guiding in the outer atmosphere environment of casing and the belt pulley of flowing through, belt, axle, bearing; play the effect of protecting simultaneously and cooling off belt pulley, belt, axle, bearing, blower fan each transmission part when carrying high temperature gas flow can normally be moved.
On the such scheme basis, under the prerequisite that guarantees the transmission system heat radiation, for saving cost, motor is positioned at outside the casing with the belt pulley that is connected with motor.Adopt the axial-flow blower of the band isolated chambers of this belt driven type, electric machine external, make high temperature gas flow without motor, transmission shaft, bearing, belt, belt pulley.Can solve motor and transmission part needs the problem of cooling heat dissipation.
Described insulation blocking chamber can select for use special steel to make.Described transmission shaft, bearing, belt, belt pulley are protected by special steel isolated chambers.
The beneficial effects of the utility model are:
Different with conventional axial-flow blower is that low-temperature airflow just through impeller, can play the effect of injection Cryogenic air cooling transmission system earlier through behind the insulation blocking chamber of settling transmission shaft, bearing, belt, belt pulley etc.And conventional axial-flow blower is an air-flow process impeller earlier, just passes through transmission part at last, so conventional axial-flow blower can't play the effect of injection Cryogenic air cooling transmission system;
Electric machine external, transmission shaft, bearing, belt, belt pulley carry out insulation blocking by the insulation blocking chamber, and high temperature gas flow is without motor, transmission shaft, bearing, belt, belt pulley;
This belt transmission high-temperature axial flow fan is applied in the air bells exhauster, upward type roof extract unit especially, and effect is remarkable.

Embodiment
See also shown in the structural representation of Fig. 1 the utility model belt transmission axial-flow blower; the belt transmission high-temperature axial flow fan; comprise fan casing 2 and be fixed on motor 9, impeller 6 outside the casing 2 and the transmission system that constitutes by transmission shaft 5, bearing 8, belt 11, belt pulley 3,10; wherein; transmission shaft 5, bearing 8, belt 11, belt pulley 3 are positioned at insulation blocking chamber 4; transmission shaft 5 one ends are connected with belt pulley 3; the other end is connected with impeller 6; bearing 8 is fixed on the transmission shaft 5, the low-temperature airflow impeller 6 of flowing through again after the transmission system of flowing through.
Among the figure, fan casing 2 comprises fans entrance flange 1 and blower fan outlet(discharge) flange 7, and the belt pulley 10 that is connected with motor 9 is positioned at outside the casing 2, and belt 11 is fixed on the belt pulley 3,10, rotates through transmission shaft 5 impeller 6.Steel design is adopted in insulation blocking chamber 4.
See also shown in the working principle schematic representation of Fig. 2 the utility model belt transmission axial-flow blower, its working principle is as follows:
Owing to adopt the utility model structure, thereby can make air-flow, just pass through impeller 6 then earlier through the isolating and protecting chamber 4 of transmission system;
When impeller 6 runnings, high speed flow velocity effect because of a large amount of high temperature gas flows, the transmission system isolating and protecting chamber 4 inner negative pressure that form, the cryogenic gas of casing 2 outsides pours in the transmission system isolating and protecting chamber 4, play cooling bearing 8/ transmission shaft 5/ belt 11/ belt pulley 3,10 effect avoids being subjected to the direct influence and the destruction of high temperature gas flow, guarantee blower fan continuously and normal operation;
In sum, the blower fan structure of the type serves as that operation steady in a long-term is laid a good foundation to improve structure as method, and reaches the purpose of environmental protection by considering some practical problems of discharging high temperature gas flow.
The above is preferred embodiment of the present utility model only, is not to be used for limiting scope of the present utility model, and all equalizations of doing according to the utility model change and modify, and are all the utility model claim and contain.
