Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is magnetic pole distribution schematic diagram of the invention.
Specific embodiment
It elaborates below in conjunction with attached drawing to a specific embodiment of the invention.
As shown in Fig. 1,2, the present invention include shell 6, metal plate 1, upper thermal insulation layer 2, magnetic pole 3, flux material layer 4, under every
Thermosphere 5, induction coil 7 and intermediate frequency power supply 8, shell 6 are the hollow structure of upper opening made of non-magnetic material, bottom in shell
Portion is equipped with lower thermal insulation layer 5, and flux material layer 4 is housed on lower thermal insulation layer, uniformly distributed magnetic pole 3 is housed on flux material layer, is equipped in magnetic pole
Upper thermal insulation layer 2 is equipped with metal plate 1 on upper thermal insulation layer, is respectively arranged with induction coil 7 on the outside of each magnetic pole.
To guarantee that using effect, the magnetic pole 3 are cylindrical body made of magnetic material, diameter≤30 millis of cylindrical body
Rice, height≤60 millimeters.
The magnetic pole 3 has uniformly distributed M row and N column, and wherein M and N is positive integer, the wherein induction on the outside of odd-numbered line magnetic pole
The winding direction of coil be it is clockwise, the winding direction of the induction coil on the outside of even number line magnetic pole is counterclockwise；The magnetic pole 3
Equidistantly to arrange, line-spacing and column are away from equal ,≤50 millimeters；
The induction coil 7 is powered by intermediate frequency power supply 8.The material of the flux material layer and magnetic pole is iron oxygen
Body, flux material layer and magnetic pole constitute closed magnetic circuit.
Present invention heating uses electromagnetic induction heating it can be seen from above structure, placed M row, N below metal plate
Column magnetic pole, the part of corresponding metal plate is themselves directly heated above each magnetic pole, and then heat is by way of heat transfer
Metal plate upper surface is reached, increases upper surface temperature, and substantially reduce surface temperature difference.The present invention can be effectively used for papermaking
To the higher occasion of calandria surface temperature uniformity requirement in industry and scientific research, by taking paper-making industry as an example, service condition is such as
Following table:
| Surface temperature difference | It is heated to 400 DEG C of spent times | Energy consumption | |
| Traditional electromagnetic induction heating plate | 10-14℃ | 55 minutes | 30KW |
| The present invention heats plate | 2-3℃ | 32 minutes | 21KW |
