Abstract
The utility model discloses an electromagnetic induction heating coil, which comprises an electromagnetic coil, an outer-layer plate and an inner-layer plate contacting with the surface of a heated device, wherein the flat electromagnetic coil is clamped between the inner-layer plate and the outer-layer plate and adhered on the inner side of the outer-layer plate, a beginning terminal and a final terminal of the electromagnetic coil are led out by wiring connection terminals, and the wiring connection terminals are fixed to the outer side of the outer-layer plate by the aid of bolts. The electromagnetic induction heating coil can solve the problems of incapability of being used on equipment, in planar structures or square structures, such as molds, die heads and the like, inconvenient disassembly, assembly and fixation and the like of an existing electromagnetic coil, and the detaching, and broadens the applicable range of electromagnetic induction heating technology.
Description
Technical field
The utility model relates to a kind of electromagnetic induction heating coil.
Background technology
The application of electromagnetic induction heating technology increases year by year, particularly in the application of industries such as plastics, untreated oil line, the trend that substitutes original electric resistance wire heating is arranged greatly.The field that existing electromagnetic induction heating technology is used, the outward appearance that is heated equipment all is cylindrical structure basically, advantages such as firing rate is fast, energy-conservation are arranged, but this mode of heating can not use but on the equipment of planar structure such as mould, die head or square structure.Reason has:
1, square such as mould, die head is heated the equipment appearance many spare and accessory parts, as hydraulic cylinder, and cylinder, cooling water pipes etc. can't coat heat-preservation cotton and solenoid on shell;
2, mould, die head are the equipment that needs frequent dismounting, maintenance, use the above-mentioned solenoid can not fast assembling-disassembling, can not be repeatedly used;
3, equipment appearance such as mould, die head compactness uses above-mentioned solenoid to be fixed on the equipment of being heated well, and coil is mobile easily, can cause the inductance value of solenoid to change, and causes unnecessary fault.
The utility model content
The purpose of this utility model is to provide a kind of novel electromagnetic induction heater coil, it can solve existing solenoid can't be on the equipment of planar structure such as mould, die head or square structure use and dismounting, fixing problem such as inconvenience, make that the range of application of electromagnetic induction heating technology is more extensive.
For this reason, the utility model provides following technical scheme:
A kind of electromagnetic induction heating coil, comprise solenoid body, lamina rara externa be heated the inner plating that equipment surface contacts, solenoid is clipped between inner plating, the lamina rara externa; Described solenoid is a platypelloid type, and solenoid sticks to the lamina rara externa inboard, and top and the null terminator Null of solenoid are drawn by binding post, and described binding post is by being bolted to the lamina rara externa outside.
Described inner plating and lamina rara externa are fixed by removably, be provided with frame and fixed around inner plating and lamina rara externa.Described inner plating is the glass fibre thermal insulation board, and lamina rara externa is an epoxy resin board.
Be provided with heat-insulation layer between described inner plating and the solenoid, this heat-insulation layer is the alumina silicate heat-insulation layer.
Adopt electromagnetic induction heating coil of the present utility model, have following good effect:
1, the dismounting of solenoid, installation become very easy, and solenoid also can be repeatedly used;
2, can be that being heated of plane used the electromagnetism heating on the equipment on the surface, and firing rate be fast, has reduced warm-up time;
3, electromagnetic heating coil can be provided with the installation site arbitrarily, and can not move after the coil stationary, and it is highly stable to become when making work.
Electromagnetic induction heating coil of the present utility model can be widely used in the equipment that mould, die head etc. need heat on planar structure, also can be used for the plastics machinery equipment of square structures such as twin-screw.
Description of drawings
Fig. 1 is a kind of electromagnetic heating coil example structure of the utility model schematic diagram.
Embodiment
Below, further specify embodiment of the present utility model in conjunction with the accompanying drawings and embodiments.
Referring to accompanying drawing.The electromagnetic heating coil integral body of present embodiment is square, be fixed together by inner plating 1, heat-insulation layer 4, solenoid 3, lamina rara externa 2 successively, among the figure, 5 is top of solenoid, 6 is the null terminator Null of solenoid, top 5 and null terminator Null 6 are drawn by ceramic binding post 7, and described ceramic binding post is by being bolted to the lamina rara externa outside.During use, can directly the inner plating of electromagnetic heating coil be fitted in the surface of the equipment of being heated.
Because inner plating directly contacts with being heated equipment surface,, make as adopting resistant to elevated temperatures glass fibre thermal insulation board so described inner plating need adopt exotic material to make.Solenoid sticks on the lamina rara externa with high-temperature plastic, and this lamina rara externa can be epoxy resin board.Described heat-insulation layer is the alumina silicate heat-insulation layer, this alumina silicate heat-insulation layer is clipped in solenoid and inner plating is between the refractory glass fibre thermal insulation board, can avoid the solenoid temperature too high, except having the effect of above-mentioned insulation, heat-insulation layer also has the effect that solenoid and inner plating are kept apart, solenoid and inner plating are when the 1.5-2cm, and promptly during the preferred 1.5-2cm thickness of heat-insulation layer, solenoid can Fast Heating.Coil can be distinguished coiling according to different specifications and power, and the installation site of solenoid also can be reserved according to the requirement of equipment installation site.
The inner plating and the lamina rara externa of present embodiment are fixed together by screw.For increasing this electromagnetic heating coil intensity, guarantee that it can not be out of shape in heating process, can be further in addition frame 8 is fixing around inner plating that is fixed together and lamina rara externa, described frame can adopt stainless steel material to make.
The foregoing description only is enumerating the utility model technical conceive way of realization; protection range of the present utility model is not limited only to the foregoing description, and protection range of the present utility model may extend to those skilled in the art according to the thinkable equivalent technologies means of technical conceive of the present utility model.
