Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is elaborated.
By Fig. 1, shown in 2, the present invention include shell 6, metal plate 1, upper thermal insulation layer 2, magnetic post 3, flux material layer 4, under every
Thermosphere 5, induction coil 7 and intermediate frequency power supply 8, the hollow structure of the upper opening that shell 6 is made for nonmagnetic substance, shell inner bottom
Portion is equipped with lower thermal insulation layer 5, equipped with flux material layer 4 on lower thermal insulation layer, equipped with uniform magnetic post 3 on flux material layer, on magnetic post equipped with
Upper thermal insulation layer 2, equipped with metal plate 1 on upper thermal insulation layer, is respectively arranged with induction coil 7 outside each magnetic post.
For ensureing using effect, the cylinder that described magnetic post 3 is made for magnetic material, cylindrical diameter≤30 milli
Rice, highly≤60 millimeters.
Described magnetic post 3 has uniform M row and N row, and wherein M and N is positive integer, wherein the sensing outside odd-numbered line magnetic post
The winding direction of coil is that the winding direction of the induction coil outside even number line magnetic post is counterclockwise clockwise;Described magnetic post 3
For equidistantly arrangement, line-spacing and row away from equal, all≤50 millimeters;
Described induction coil 7 is to be powered by intermediate frequency power supply 8.The material of described flux material layer and magnetic post is ferrite, magnetic
Material layer and magnetic post constitute closed magnetic circuit.
By said structure it can be seen that the present invention heats employing electromagnetic induction heating, below metal plate, placed M row, N
Row magnetic post, the part of metal plate corresponding above each magnetic post is all themselves directly heated, and then heat is by the way of conduction of heat
Arrive metal plate upper surface, make upper surface temperature raise, and make surface temperature difference be substantially reduced.The present invention can be effectively used for papermaking
Occasion higher to calandria surface temperature uniformity requirement in industry and scientific research, as a example by paper-making industry, service condition is such as
Following table:
Surface temperature difference | It is heated to 400 DEG C of spent times | Energy consumption | |
Tradition electromagnetic induction heating flat board | 10-14℃ | 55 minutes | 30KW |
The present invention heats flat board | 2-3℃ | 32 minutes | 21KW |
