In agricultural and pastoral farming, greenhouse culture technique and livestock and poultry facility cultivation technology proportion in agricultural and livestock technology improves day by day.Ambient temperature is huge for greenhouse production and livestock and poultry cultivation influence, for the greenhouse can be remained in the relative constant scope with the interior temperature of livestock and poultry house, generally the conduction that the insulation measure comes the air lock internal and external temperature to be set, be reduced to the energy consumption that keeps temperature stabilization.Usually the measure of taking is to use the inflation curtain device of thin-film material to be incubated, to guarantee the needs of plant growing growth and growth of animals or poultry condition.By the inflation between the bilayer film material, make and maintain certain air between the bilayer film, the low heat conductivity that utilization is enclosed in air static between the film can come effectively to completely cut off the inside and outside heat exchange in greenhouse, and the effect of playing insulation is given up in greenhouse and livestock and poultry.In the inflation curtain device of greenhouse and livestock and poultry house, generally all exist air in certain amount to reveal, need item wherein to replenish an air and keep inflation curtain inner air pressure, normally adopt aeration blower fan to realize inflating operation, relatively more commonly used is centrifugal aeration blower fan.The centrifugal aeration blower fan of prior art generally is to use motor as motive force, and by the rotation of driven by motor impeller, air stream blasts between the bilayer film through volute, just can realize certain air pressure is inflated and kept to duplicature with the motor of smaller power.Existing centrifugal aeration blower fan in use when motor increases the electric current of motor owing to the reason of mechanical aspects causes stall or motor power reason, causes motor temperature to raise, and will cause motor to be burnt when motor temperature raises when surpassing rated temperature.How to make motor can when temperature is elevated to certain limit, make motor automatically outage be that motor can be switched on automatically and recovered running after temperature is reduced to uniform temperature with the protection motor, become the problem that the technician need solve; Simultaneously, the rising of temperature is worked the electric capacity in the starting circuit for a long time during machine operation under higher temperature, and shorten its working life, influences the reliability of aeration blower fan work; And, be the fan blade that runs up in the intake grill that volute of blower exposes, the user is easy to come to harm because of carelessness.
The model utility content
In order to solve the technological deficiency that prior art exists, the purpose of this utility model is to provide a kind of improved centrifugal aeration blower fan, cut off the electricity supply when temperature was elevated to certain limit when it can make machine operation, turn-on power is resumed work when temperature is reduced to certain limit; Electric capacity in its circuit can be worked at a lower temperature, prolongs its working life; Improve blower fan Security in use.
To achieve these goals, the technical solution of the utility model is:
A kind of centrifugal aeration blower fan, comprise single-phase asynchronous motor, spiral case, impeller, intake grill, exhaust outlet, motor is fixed on the spiral case, and an end of motor output shaft connects impeller, wherein: heat protector is connected in the stator winding circuit, covers and be fixed on the staor winding by insulating bush; Electric capacity is placed in the electric capacity cover, and the electric capacity cover is spiral case exhaust outlet place fixedly; The air intake mouth mask is fixed on the spiral case intake grill.
Heat protector is covered with wiring by insulating bush and is fixed on the staor winding.
Heat protector is that break-off signal is that 130 ℃ ± 5 ℃, recovery temperature are 90 ℃ ± 15 ℃ heat protector.
Electric capacity is fixed on spiral case exhaust outlet 50mm place by the electric capacity cover with tapping screw.
The air intake mouth mask is fixed with the attachment hole of tapping screw and spiral case air intake.
Blower fan surface and air intake mouth mask are sprayed with the black layer of moulding.
Draught fan impeller is the multiple-airfoil type impeller.
Because after adopting such scheme, the utility model in use is fixed on the heat protector insulation that is connected on stator winding circuit on the staor winding, perception stator temperature, the protection motor of when stator temperature surpasses specified serviceability temperature scope, cutting off the electricity supply; Electric capacity is transferred to volute of blower exhaust outlet place by the electric machine casing of common placement, it is under the lower operating temperature, prolonged the working life of electric capacity; At the volute of blower intake grill air intake mouth mask is set, has prevented that effectively foreign matter from entering in the volute of blower, protected the safety of aeration blower fan and user's personal safety.
