Embodiment
Below in conjunction with the drawings and specific embodiments the drawback how the utility model overcomes prior art at work is explained in detail.
Those skilled in the art understands, electromagnetic inductive heating principle is to utilize maxwell's Theory of Electromagnetic Field, promptly the magnetic field of Bian Huaing produces electric field in the space around, and when conductor was in this electric field, the free electron in the conductor is done directed moving and produced electric current under the electric field force effect be induced current.Wind-cooling type electromagnetic induction heating roller of the present utility model promptly utilizes this principle to make.Generally speaking, the electromagnetic induction heating coil of warm-up mill inside generally is higher than 50～100 ℃ than roll surface temperature, therefore, the occasion of higher heating-up temperature is being provided, the operating ambient temperature of electromagnetic induction heating coil is very high, if can not efficiently radiates heat, the operating efficiency of the electronic devices and components in the electromagnetic induction heating roller be very low, and be easy to damage, the while is the useful life of serious threat solenoid also.
Fig. 1 illustrates the structural representation of the utility model embodiment one.7 is the axle of electromagnetic induction heating roller roller among the figure, and axle 7 maintains static, above rigid bearing 8, realize the rotation of roller 1 by the rotation of bearing 8.The inner chamber of electromagnetic induction heating roller roller 1 is fixed a columniform inner core 4.Described electromagnetic induction heating coil 3 is fixed on the special support 5, and described support 5 is fixed on the axle 7.The cooling air that enters roller 1 inner chamber from a side of axle 7 passing around inner core 4 equably, form air channel 6, final opposite side from axle 7 distributed after cooling air in the air channel 6 was taken away the roller temperature inside, can take away the heat of roller 1 inside with this, thereby can reduce the working temperature of electromagnetic induction heating coil 3, effectively guarantee the operating efficiency and the useful life of coil.
In roller 1 inside, also be covered with one deck thermostable heat insulation layer 2.The purpose that the high temperature resistant heat insulation layer is set is effectively the roller 1 and the circulation cooling air of roller 1 inner chamber to be isolated, avoid the heat of roller 1 can not taken away mistake by the cooling air of roller 1 inside cavity circulation, guarantee the heating-up temperature of roller 1, effectively improve the efficiency of heating surface.Another purpose is to protect electromagnetic induction heating coil 3 not by 1 hyperthermia radiation of the roller after the heat, thus useful life that effectively can extension coil.
The position of described thermal insulation layer 2 can be determined according to actual conditions.As shown in Figure 1, described thermal insulation layer 2 tightly is coated on the surface of electromagnetic induction heating coil 3 towards roller inwall one side.In addition, thermal insulation layer 2 can also closely be arranged on the inwall of roller 1, as shown in Figure 2.Thermal insulation layer is arranged on this two positions, can effectively realize heat insulation purpose, these two kinds of embodiment that structure all is a comparative optimization.Wherein, the fixed-site that is provided with of thermal insulation layer 2 shown in Figure 1 is got up more conveniently, and therefore, the position of thermal insulation layer 2 is a preferred embodiment in embodiment illustrated in fig. 1 one.
Except that above-mentioned two kinds of positions, described thermal insulation layer 2 also has a kind of position, promptly is coated on the surface of support 5 towards roller one side, the surface that 3 of electromagnetic induction heating coils are close to thermal insulation layer 2 towards roller inwall one side.As shown in Figure 3.Though this structure setting can make thermal insulation layer effectively isolate the loss of roller 1 heat, can make electromagnetic induction heating coil by the roller thermal radiation of heat.But under the situation of good at electromagnetic induction heating coil use high-temperature resistant result, as to be not easy oxidation high temperature wire (as silver-colored line), this position also is a kind of reasonable selection owing to fixing more convenient.
Described thermal insulation layer 2 is the inorganic high-temperature resistant thermal insulation layer.So long as can play the high temperature resistant material of effect of heat insulation, all within scope of the present utility model.
Among another embodiment of the present utility model, inner core 4 is not set, but allows cooling air directly enter the inner chamber of roller 1, at the fixing choked flow net 9 of the opposite side of axle 7, as shown in Figure 4 from a side of axle 7 in described roller 1 inside cavity.The purpose that choked flow net 9 is set is in order to regulate the speed of the cooling air that enters roller 1 inner chamber.The surface of described choked flow net 9 has several apertures, by the number and the big or small cooling requirement that realizes roller 1 inside of perforate.According to the purpose of this utility model, the shape of the surperficial aperture of described choked flow net 9 can be circular, also can be other shapes such as triangle.Make different shape that wind energy passes through all within scope of the present utility model as long as those skilled in the art will recognize that.The hole of opening on the surface of choked flow net 9 among the embodiment of the present utility model is circular, as shown in Figure 5.
In sum, above embodiment is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
