Description
Technical field
The present invention relates to a kind of air-conditioning device, especially relate to a kind of air curtain device of employing impeller rotation.
Background technology
Air curtain is to form the invisible door curtain of one side by the airflow that centrifugal wind wheel produces, therefore, also known as wind curtain machine, air curtain, air gate.This machine is arranged on to be needed above the building doorways such as heat-insulated market, theater, hotel, restaurant, conference hall, freezer, operating room and household or the left and right sides, start this machine, air-flow can separate the air of indoor and outdoor, both easy access, can prevent indoor and outdoor air from exchanging again.Meanwhile, have again dust-proof, anti-pollution, the effect of anti-mosquito, be widely used in electronics, instrument, pharmacy, food, Precision Machining, chemical industry, the industry such as shoemaking and service, business.
Existing air curtain typically has two kinds; one kind is natural wind air curtain; rotated by power source impeller; from air curtain air inlet suction airflow, after accelerating through impeller, directly discharge from air outlet; power source is typically protected by Overtemp. protector; break down in power source or wheel rotation is abnormal, when causing power source local temperature or bulk temperature extremely to raise, carry out power-off protection.But overtemperature prote mode is only power source internal local small range monitoring temperature; the exception failing effective full working scope monitoring air curtain impeller slowly runs or even stall; it is possible to cause that power ource electric current is excessive, temperature anomaly is too high, or even causes naked light, involve air curtain periphery article.
Another kind is hot blast air curtain, integrates air heating module by above-mentioned natural wind air curtain and forms, rotated by power source impeller, from air curtain air inlet suction airflow, after heating by heater block, accelerate air-flow by impeller, finally discharges from air outlet.The overtemperature prote mode of existing hot blast air curtain heater block be heater block surface or near install heat transfer formula temperature Overtemp. protector, carry out power-off protection in power breakdown.But, the overtemperature prote mode misoperation of existing thermal conductivity frequently, usually causes the maximum error of temperature sense because of installation site slight errors, thus the accuracy of the monitoring temperature of impact heater block, and then lead to the job stability of hot blast air curtain.
Accordingly, it would be desirable to invent a kind of new air curtain solve the above problems.

The present invention is directed to the deficiency that above-mentioned prior art exists, and provides a kind of new air curtain, when air curtain impeller abnormal, can make and correctly and timely process the use safety it is ensured that equipment and user.
The present invention in order to realize above-mentioned technical purpose, using following technological means：
A kind of fully mechanized workface air curtain and water mists linkage dust-removing method, include power source, the impeller by described power source drive, be arranged at shell outside described power source and impeller, the switching device being arranged on described shell, air inlet, air outlet, air-flow accelerate air channel, described air curtain also includes the velometer for monitoring impeller working condition being electrically connected to each other and the control device for controlling power source to rotate, described velometer is arranged on the axle ends of described impeller, and described control device is arranged on described air curtain shell medial surface.
Described velometer is arranged between described impeller and power source, monitors described impeller working condition, and sends a signal to described control device.
Described air curtain also includes the heating wire for heating air.
Described velometer is tachoscope.
Described control device is trigger.
Described velometer is tachoscope, and described control device is trigger.
Described impeller is one or two, and is installed on the side of described power source.
Described impeller is centrifugal blower.
Described impeller is tubular wind wheel.
Normally whether the fully mechanized workface air curtain that the present invention provides and water mists linkage dust-removing method, effectively full working scope monitoring air curtain impeller, can make and correctly and timely process the use safety it is ensured that equipment and user.
