Abstract
The utility model relates to a device which is arranged in buildings for exhausting smoke caused by a fire, in particular to an induced fire-extinguish smoke exhaust blower of motor heat radiation system. The utility model mainly comprises a shell, an impeller, an induction unit, a motor, a guide vane, an inner cylinder, a heat radiating air intake tube, etc. With the induction unit arranged at an air vent in the outer side of the inner cylinder, the utility model makes air in the inner cylinder go out of the induction unit and makes air outside the machine come into the inner cylinder through the heat radiating air intake tube to cool the motor under the induction and entrainment generated when the high-speed smoke flows through the induction unit, thereby needing no motor heat radiating impeller, improving efficiency of the blower, reducing noise, simplifying a structure and reducing cost.
Description
The utility model relates to a kind of being installed in the building that fire-fighting smoke evacuation requires, and when fire takes place, is responsible for the equipment of discharge fire smoke, particularly a kind of novel induction type motor radiating system smoke exhaust fan.
Smoke exhaust fan in the past all adopts bilobed wheel and inside and outside barrel structure.Fire smoke by the main impeller of blower fan by outside the urceolus discharge machine.The heat that places the motor of inner core to produce at running is outside the motor radiating system discharge machine of being made up of Heat-dissipating impeller of motor, heat radiation suction tude and heat radiation steam outlet pipe.Be not communicated with mutually between the inner/outer tube, jeopardize motor with the high-temperature flue gas of avoiding fire to produce.Because Heat-dissipating impeller of motor consumed power and generation noise increase the overall power of blower fan and noise.When double speed smoke exhaust fan especially, low-speed running were used at ordinary times ventilation, the gas of being carried was gas at normal temperature, so motor needn't be provided with sink separately, Heat-dissipating impeller of motor this moment consumed power and the extra noise that increases in vain.
The purpose of this utility model is according to aerodynamic principle, utilize blower fan in discharging the flue gas process, the inducing action that flue gas flow produces, the inhalation machine outer air, be motor radiating, thereby the cancellation Heat-dissipating impeller of motor, the novel smoke exhaust fan that to provide a kind of efficient higher, noise is lower, designs simplification and cost descend.
The purpose of this utility model realizes by following technological scheme:
Induction type motor radiating system smoke exhaust fan mainly is made up of parts such as casing, impeller, persuader, motor, stator, inner core and heat radiation suction tude.Impeller is installed on the motor shaft, and by the rotation of motor direct-drive impeller, motor is fixed in the inner core, and the axial direction of motor is consistent with the axial direction of casing.Stator is installed between inner core and the casing.Persuader is installed in air outlet hole place on the inner tank theca.The heat radiation suction tude is communicated with the inlet hole and the machine of inner core outward.So just constituted induction type motor radiating system smoke exhaust fan.When blower fan turns round, flue gas flow enters impeller, after the impeller acting, enter between blower fan inner core and the casing, when flue gas flow process persuader, because the inducing action of high speed flue gas flow, air in the inner core is drawn from persuader, and the machine outer air is replenished into inner core from the heat radiation suction tude, behind the heat that the absorption motor distributes, drawn from persuader again, thereby be reached for the effect of motor radiating.
The utility model has saved Heat-dissipating impeller of motor owing to adopted induction type motor radiating system, makes blower fan improve efficient, has reduced noise, and has simplified the structure, and has saved cost.
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Impeller [2] is fixed on the axle of motor [4], and motor [4] is fixed on the inner core [6], and inner core [6] is connected with casing [1] with stator [5], and stator [5] had both play a part to support inner core [6], also played guide functions.The persuader [3] of several elbow shapes or similar elbow shape is positioned at air outlet hole place on inner core [6] outer wall, and the Way out of persuader [3] is a downbeam, promptly along the direction of flue gas flow.Heat radiation suction tude [7] goes up inlet hole with the inlet hole of inner core [6] with casing [1] and links to each other, and the inlet hole and the machine of inner core [6] are interlinked to the outside.When the high speed flue gas flow on every side the time, forms induce entrainment effect in the outlet port of persuader [3] through persuader [3], the air in the inner core [6] is drawn from persuader [3].The machine outer air is replenished into inner core [6] by heat radiation suction tude [7], and in inner core [6], around motor [4], flow to the direction of persuader [3], after in flow process, absorbing the heat that motor [4] distributes, drawn from persuader [3] again, and back discharge machine is mixed in the outlet port of persuader [3] with flue gas flow outside.
Claims (2)
1. induction type motor radiating system smoke exhaust fan, mainly form by casing [1], impeller [2], persuader [3], motor [4], stator [5], inner core [6] and heat radiation suction tude [7] etc., the motor [4] that it is characterized in that described induction type motor radiating system smoke exhaust fan places inner core [6], persuader [3] places air outlet hole place on inner core [6] outer wall, the shape of persuader [3] is elbow shape or similar elbow shape, the Way out of persuader [3] is a downbeam, promptly along the direction of flue gas flow.
2. induction type motor radiating as claimed in claim 1 system smoke exhaust fan is characterized in that the inlet hole of described inner core [6] is connected with machine by heat radiation suction tude [7] outward.
