The beneficial effects of the utility model are: by impeller inducer to line shaft, motor carries out the synchronous heat radiation in working procedure, thus ensure that transmission shaft moderate finite deformation can not occur, effectively can maintain the stability that axle head coordinates, noise is avoided to increase, reduce structure quake, the isostructural reasonable working temperature of motor can be maintained simultaneously, avoid the meaningless shortening of external structure life-span, in spiral case, there is the structure that is sealed and matched, the rotational stability of power system can either be improved, hot air flow in spiral case can be avoided again, impurity flows out, maintain ex-ternal transmission core texture and be in normal temperature, in clean working environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model;
Fig. 3 is the structural representation at the utility model sealing wallboard place.
In figure: volute of blower 1, intake grill 2, exhaust outlet 3, axle sleeve 4, line shaft 5, outer power motor 6, external air cooling system impeller 7, wind gathering cover 8, observation door 9, outlet pipe 10, import expansion joint 11, outlet expansion joint 12, containing groove 13, sealing wallboard 14, asbestos ring 15.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As Fig. 1, Fig. 2, in embodiment shown in Fig. 3, a kind of combustion system wind-guiding blower fan, comprise volute of blower 1, described volute of blower is provided with intake grill 2, exhaust outlet 3, impeller inducer is provided with in described volute of blower, described impeller inducer is provided with an axle sleeve 4 coaxial with impeller inducer, described axle sleeve is socketed in one end of a line shaft 5, described line shaft is through spiral case shell wall, the power source of described line shaft is an outer power motor 6, described line shaft is provided with external air cooling system impeller 7, described external air cooling system impeller is coaxial with line shaft, described external air cooling system impeller is in outside spiral case, described outer power motor is provided with the wind gathering cover 8 of one end open, described wind gathering cover is towards spiral case, the blowing direction of described external air cooling system impeller is towards the opening of wind gathering cover, described spiral case is provided with observes door 9.
In spiral case, air-flow passes through, and the mechanism of wind-guiding is impeller inducer, and the power source of wind-guiding is outer power motor.In working procedure, because gas flow temperature is higher, can conduct heat to line shaft from inside to outside, outer power motor etc., and external air cooling system impeller is arranged on line shaft, outside spiral case, therefore synchronously radiating airflow can be produced, when radiating airflow blows on blower fan, due to the existence of wind gathering cover, the compacted gathering of meeting, blow to or rebound and flow to line shaft, thus ensure wind gathering radiating effect, can to line shaft, outer power motor, the external structures such as axle head cooperating structure carry out heat radiation dimension temperature, thus avoid ex-ternal transmission structure to be excessively heated after heat bulging deformation and the vibrations caused, unstable, the problems such as noise change is large.
