Abstract
The utility model discloses a special fan for high-temperature smoke-exhausting fire fighting. The special fan comprises a base, a motor, a fan outer barrel, an inner barrel, an impeller, a flow deflector, a cooling impeller, an air inlet, an air outlet and a flow guiding cone. The special fan is characterized in that the air inlet is arranged at the left end of the fan outer barrel, the air outlet is arranged at the right end of the fan outer barrel, the inner barrel is fixedly installed in the fan outer barrel, the motor is installed at the position of the middle of the inner barrel, the impeller is installed on a spindle positioned at the front end of the motor, the inner barrel positioned in the front of the impeller is provided with a cold air inlet pipe, and the cold air inlet pipe penetrates through the top of the fan outer barrel. The cooling impeller is installed on the spindle positioned at the rear end of the motor, the inner barrel positioned on the lower portion of the cooling impeller is provided with a cold air outlet pipe, and the cold air outlet pipe penetrates through the lower end of the fan outer barrel. The special fan is simple in structure and convenient to install, air pressure and air quantity are large, power consumption quantity is low, and high temperature resistance is good.
Description
Technical field:
The utility model relates to a kind of Fan Equipment, particularly a kind of high temperature smoke evacuation fire-fighting special fan.
Background technique:
But the big blast of existing axial fan air quantity is low, and the centrifugal fan blast is high, air quantity is little and unstable.Mixed flow fan is the blower fan of a kind of boundary between axial fan and centrifugal fan, and its wind stress factor is higher than axial-flow blower, and flow coefficient is bigger than centrifugal blower, combines the advantage of two kinds of blower fans, and purposes is comparatively extensive.Shortcomings such as but there is complex structure in existing mixed flow fan, and operating noise is big, incoming air area is little, soundproof effect is bad, working life is short have influenced the usability of mixed flow fan.When the building breaking out of fire, be accompanied by dense smoke and high temperature, common axial-flow blower and flow-mixing blower fan all can not satisfy the requirement of high temperature smoke evacuation, need a kind of smoke exhaust fan of special use to replace traditional blower fan.
The model utility content:
The utility model is to the deficiency of existing technology, and a kind of high temperature smoke evacuation fire-fighting special fan is provided, and has simple in structure, easy for installation, blast and air quantity is big, power consumption is low, resistance to high temperature is good advantage.
In order to achieve the above object, the utility model adopts following technological scheme:
A kind of high temperature smoke evacuation fire-fighting special fan comprises base, motor, blower fan urceolus, inner core, impeller, guide plate, cooling wheel, intake grill, exhaust outlet and flow deflecting cone, and it is characterized in that: blower fan urceolus left end is provided with intake grill, right-hand member is provided with exhaust outlet; Inner tube installation is fixed in the blower fan urceolus; Motor is installed in the inner core neutral position, and impeller is installed on the motor front end main shaft, offers the cold wind air intake pipe on the inner core of impeller front portion; The cold wind air intake pipe passes the top of blower fan urceolus; The rear end main shaft of motor is equipped with cooling wheel, offers the cold wind air outlet tube on the inner core of cooling wheel bottom, and the cold wind air outlet tube passes the lower end of blower fan urceolus.
Further, be fixed with the guide plate that favorable current reverses between inner core and the blower fan urceolus, inner core the right is fixedly connected with flow deflecting cone.
Beneficial effect: the utility model is simple in structure, easy for installation, blast and air quantity is big, power consumption is low, resistance to high temperature is good.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, base, 2, motor, 3, intake grill, 4, the cold wind air intake pipe, 5, impeller, 6, exhaust outlet, 7, the blower fan urceolus, 8, guide plate, 9, inner core, 10, cooling wheel, 11, flow deflecting cone, 12, the cold wind air outlet tube.
Embodiment:
Embodiment 1: as shown in Figure 1; A kind of high temperature smoke evacuation fire-fighting special fan comprises base 1, motor 2, blower fan urceolus 7, inner core 9, impeller 5, guide plate 8, cooling wheel 10, intake grill 3, exhaust outlet 6 and flow deflecting cone 11, and blower fan urceolus 7 left ends are provided with intake grill 3, right-hand member is provided with exhaust outlet 6; Inner core 9 is fixed in the blower fan urceolus 7; Motor 2 is installed in inner core 9 neutral positions, and impeller 5 is installed on the motor 2 front end main shafts, offers cold wind air intake pipe 4 on the inner core 9 of impeller 5 front portions; Cold wind air intake pipe 4 passes the top of blower fan urceolus 7; The rear end main shaft of motor 2 is equipped with cooling wheel 10, offers cold wind air outlet tube 12 on the inner core 9 of cooling wheel 10 bottoms, and cold wind air outlet tube 12 passes the lower end of blower fan urceolus.Be fixed with the guide plate 8 that favorable current reverses between inner core 9 and the blower fan urceolus 7, inner core 9 the right are fixedly connected with flow deflecting cone 11.
