Description
Technical field
The utility model relates to a kind of smelting equipment, relates in particular to the electromagnetic induction heater of a kind of charged road checkout gear.
Background technology
Induction heating is to utilize electromagnetic induction principle, power supply is toward coil input power frequency, intermediate frequency or high-frequency alternating current, coil produces alternating magnetic field, and workpiece is placed in this alternating magnetic field, and workpiece produces the induced current of same frequency, this induced current is inhomogeneous in the distribution of workpiece, strong on the surface, and very weak in inside, arrive heart portion close to zero, utilize this kelvin effect, surface of the work is heated rapidly.Oneself is widely used in a plurality of fields such as the quenching of Industrial Metal piece surface, Metal Melting, bar be diathermanous induction heating.
Induction heater generally includes induction heating power and coil, and induction heating power provides the alternating current that needs frequency for coil.The coil major part is tubulose, and the alternating magnetic field that this tubular coil produces is bigger in the inside and outside strength ratio of coil, and just smaller at the both ends of coil, therefore, usually the workpiece of needs heating is placed on inside or the outside of coil.
Usually adopt the electrothermal tube heating at present at home, because the electrothermal tube heating is slow, firing equipment is just done very big very longly, the big and complex structure of floor space.Have in Japan and to adopt electromagnetic induction to come generator amature, stator heating for workpiece being placed on the inside of tubular coil, have been designed special-purpose manipulator, and coil need do very greatly, the entire equipment structure is very complicated, and cost is very high.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of low in energy consumption, cost is low, power saving effect, has the electromagnetic induction heater that tracking velocity is fast, precision is high.
In order to overcome the defective that exists in the background technology, the utility model solves the technical scheme that its technical problem adopts and is:
The electromagnetic induction heater of a kind of charged road checkout gear, comprise the three phase mains, mains switch, the contactor that are electrically connected successively, also comprise induction power supply heating controller, circuit checker, the input of described induction power supply heating controller is connected with the output of described circuit checker, the input of described circuit checker is connected with the output of described contactor, and the output of described induction power supply heating controller is connected with load coil; Described load coil is wrapped in the outer surface of insulating; Described insulating is nano heat insulating material; Described circuit checker comprises contact modules, both positive and negative polarity detection module and voltage strength detection module, described contact modules comprises two contact pins, described contact pin contacts positive pole and the negative pole of circuit to be detected respectively, described both positive and negative polarity detection module is connected with described contact modules, described voltage strength detection module is connected with described contact modules, and described voltage strength grade is corresponding with default range of voltage values.
Described induction power supply heating controller also is connected with the PLC controller with the PC host computer respectively.
The outer surface of described insulating is provided with for the wire casing of placing described load coil.
The utlity model has low in energy consumption, cost is low, power saving effect, has fast, the precision advantages of higher of tracking velocity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
