The purpose of this utility model is to provide that a kind of efficient height, pressure are big, low noise, environmental protection, energy-conservation pipe type smoke exhaust fan.
The technological scheme that the utility model adopted is for achieving the above object: a kind of pipe type smoke exhaust fan shell, motor, impeller and contain the cooling unit of heat insulation inner core, it is characterized in that: place the front output shaft direct connection impeller of the motor in the casing, the heat insulation inner core of cooling unit is located at the periphery of motor; Between casing and heat insulation inner core, constitute the ventilation channel of a ring-type, circumferential uniform several guide vanes in edge in ventilation channel; Described impeller is a receded disk impeller, and this blower fan also comprises one, and to be arranged at impeller outlet outer and be fixed in fluid director on the casing.
Described cooling unit is made up of heat insulation inner core, cooling wheel, suction tude and outlet pipe, cooling wheel is contained on the rear end output shaft of motor, on the circumferential position of close fan outlet one end of heat insulation inner core, be provided with interior inlet hole, have the external admission hole casing with the corresponding position of interior inlet hole heat insulation inner core, be connected with atmosphere between the inside and outside inlet hole communicate, with the obstructed suction tude of flue gas; On the circumferential position of close draught fan impeller one end of heat insulation inner core, be provided with inner vent, have outer vent casing with the corresponding position of inner vent heat insulation inner core, be connected with atmosphere between the inside and outside exhaust port communicate, with the obstructed outlet pipe of flue gas.
Along circumferential uniform guide vane, its quantity is generally 5-13 in ventilation channel, and guide vane is the three-dimension curved surface shape.The wind that has the rolling tangential direction that receded disk impeller is discharged makes wind flow out along axis by changing wind direction behind the guide vane.
Preferably this blower fan further comprises a slip ring, this slip ring is located at the suction port front end of impeller and is fixed on the casing, it is big near the intake grill place that the shape of slip ring is, and near suction eye reduce contraction-like, with suction eye connecting part rounding off, to reduce inlet's loss in efficiency.
Described casing can be for cylindric or flat column a kind of, can be directly used in the difform pipeline.
Owing to adopt receded disk impeller, the pressure of the blower fan of raising, the blower fan with the aial flow impeller of equivalent diameter under the 1450rpm rotating speed is identical at 2900rpm rotating speed pressure, so rotating speed can make noise reduce 9-15DB (A) when reducing; The guide vane of the three-dimension curved surface shape that employing and receded disk impeller match has been eliminated the eddy current in most of air-flow, has reduced the vortex in the air-flow, turbulent flow, has satisfied fluid flow conditions, has improved the efficient of blower fan.This blower fan has adopted independent reliable air cooling system, can be when fire takes place, can be when 280 ℃ of temperature, running is more than 30 minutes continuously, get rid of high temperature corrosion, toxic gas, according to fluid mechanics and aerodynamic principle, make it be applicable to GB50045-95 " Code for fire protection design of high rise buildings "; GB50067-97 " garage, freight car temporary repairing shed, parking lot design fire regulation "; And the various fire-fighting purging systems of stipulating among the GB50098-98 " civil air defense projects fire regulation ".The utlity model has advantages such as efficient, low noise, energy-saving and environmental protection, its form structure can be according to the condition of the pipe network of ventilation fire-fighting smoke evacuation, is connected into the part of pipeline with various systems.
