Description
Technical field
The utility model belongs to the heater that a kind of Electrothermal plate is used, and in the used Electrothermal plate of rubber or plastic products process equipment, also can be used for the Electrothermal plate of other heat-processing equipment.
Background technology
Generally all be to adopt the mode of electric heating tube to heat at present in the conventional electric heating flat board, the mode ubiquity heat efficiency of this electric heater for heating is low, defectives such as the heater element power consumption is big, the vulcanizer Electrothermal plate that generally uses as rubber or plastic article industry just mostly is the Electrothermal plate of electrothermal tube form, and there is following problem in the mode of heating of this Electrothermal plate vulcanizer:
1, the heat efficiency is low, because electrothermal tube is a kind of heating system of form of resistance heat, its heating efficiency itself is lower.In addition because the heat transfer process complexity: the vulcanization of rubber in electrothermal tube → flat board → mould → mould, thermal loss is bigger, and the heat efficiency is 15%～25% only, and energy waste is serious.
2, because temperature element nestles up pyrotoxin (electrothermal tube), dull and stereotyped temperature everywhere exists the variation of temperature gradient, the lack of homogeneity of temperature, the temperature of its measurement and control and the curing temperature of rubber differ bigger, Ping Ban temperature is subjected to the influence of variation of ambient temperature bigger in addition, its temperature error is about 5～20 ℃, thereby has influenced the vulcanized quality of product.
3, electrothermal tube belongs to fallible component, and spoilage is higher.Under the situation that one or a few electrothermal tube damages, be difficult to timely discovery, cause dull and stereotyped heating inhomogeneous, and make product rejection.Its maintenance capacity, maintenance cost are also bigger.
Because the Electrothermal plate of electrothermal tube form exists many deficiencies, so recently a lot of researchers are considering a kind of electromagnetism heated plate that adopts the electromagnetic field heating, but the electromagnetic heating coil that existing electromagnetism heated plate is adopted all is to adopt the electromagnetic heating coil of cylindrical helical coiling, yet the electromagnetic heating coil of this cylindrical helical coiling, magnetic core is often all arranged, and constitute magnetic induction return circuit thus, and the electromagnetic heating coil of this cylindrical helical coiling does not singly make the structure of electromagnetic heater become huge, the heating area of the electromagnetic heating coil of cylindrical helical coiling is little, the uniformity that heat is transmitted is still undesirable, and because the electromagnetic heating coil of this cylindrical helical coiling has magnetic core, magnetic core damages easily in the course of work of flat board, so necessary the improvement.
Summary of the invention
The purpose of this utility model is to provide a kind of electromagnetism heated plate surface temperature that makes more even at the deficiency of existing heated plate, and the heater volume is littler, and the electromagnetic heating coil of electromagnetism heated plate for ease of maintenaince.
According to the purpose of this utility model, the technology implementation scheme that is proposed is, utilize the principle of electromagnetism magnetic induction, the electromagnetic heating coil of electromagnetism heated plate is changed into the electromagnetic heating coil of snail shape, the coiling appearance of electromagnetic heating coil is enclosed with resistant to elevated temperatures insulating material, the two sides of electromagnetic heating coil also accompanies the sandwich plate that is made of quartz material or other resistant to elevated temperatures insulating material in addition, and be fastened on the electromagnetic heating coil of snail shape on the inner surface of electromagnetism flat board respectively according to certain arrangement mode by securing member, when alternating current when being arranged on the electromagnetic heating coil in the electromagnetism flat board, strong alternating magnetic field will be formed, this magnetic field will form the vortex shape induced current in electromagnetism flat board or heated material, the energy of this electric current changes into heat energy by the resistance in electromagnetism flat board or the heated material again, the temperature of electromagnetism flat board or heated material is raise rapidly, reach the purpose of heating.The every interior electromagnetic heating coil of electromagnetism flat board is made up of 1-4, and every group solenoid, also can be connected in parallel by being connected in series by 1-12 unicoil, or connection in series-parallel mixing connection.Can also temperature be detected by the thermal resistance that is arranged in the cover plate simultaneously, and output to the temperature display controller, control temperature by the size of adjusting the electromagnetic heating coil electric current.
Advantage of the present utility model is:
1, dull and stereotyped helical form electromagnetic heating coil heating area is big, and the good uniformity of planar surface temperature has a narrow range of temperature;
2, dull and stereotyped helical form electromagnetic heating coil does not have core structure, so heater members is not easy to damage the reliability height;
3, dull and stereotyped helical form electromagnetic heating coil is a laminated structure, so heater volume ratio column electromagnetic heating coil is much smaller, and cost of manufacture is low.
The dull and stereotyped helical form electromagnetic heating coil of this kind can be widely used in the various electromagnetism heated plates, is worthy of popularization.
