Application of electromagnetic induction heating technology in plastic machinery 1 the current government to promote universal electricity saving, joint action. And China's power shortage in the province, according to the power supply and demand situation analysis and recommendations released by the electric prison will be revealed, has reached 18. All over the country accumulated pull a switch power brownouts more than 14 million times, the cumulative power brownouts reached 19 million kilowatts, the lack of electric power has seriously control the development of the economy of our country. Therefore, the government vigorously support energy conservation, environmental protection industry. According to incomplete statistics, the existing plastic machinery for the production of about 1 million 600 thousand sets per year, increasing by 15%, the capacity of 20 million kilowatts heating part, daily consumption is about 20 million KW * 0.5 * 20 hours =2 billion kwh, heating machine (0.5 on-off ratio, 20 hours a day for the machine production), according to the 300 working days of each year, the National Plastics processing machinery annual consumption of 60 billion kwh, if all the machines are installed electromagnetic heating device, so the energy saving of about 18 billion kwh, the ratio of electricity generation in Gezhouba Dam throughout the year more than 2 billion 300 million kwh, to alleviate the state power tension, reduce government investment and has a very positive role and significance of reducing the production cost of the enterprise. 2. At present, the plastic industry competition is fierce, how to reduce the product cost, improve product competitiveness, is a central problem that every enterprise must face, and the electric energy occupies a large proportion in the cost of the plastic products industry, using electromagnetic heating technology can effectively reduce the production cost and improve the competitiveness. Domestic plastic industry status quo A. product application industry status: plastic products, plastic film, plastic granulation, drawing injection molding, pipe and other production enterprises. Currently, equipment for production of these enterprises are using electric heating coil heating of the barrel and die, plastic raw material melting plasticizing and injection molding, drawing, extrusion molding products. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; B. problems: (1) heat loss: use the enterprise existing heating mode, a resistance wire winding, circle and double side heating, heat conduction of the inner surface (close to the cylinder part) to the barrel, and outside the heat quantity in most of the loss into the air, resulting in electrical energy losses and waste. (2) the environmental temperature rise: due to the high heat loss and increasing the temperature of the surrounding environment, especially in summer on the production environment influence, field working temperature more than 45 DEG C, some enterprises had to use air conditioning temperature decreases, which in turn cause energy of secondary waste. (3) the use of short service life, maintenance: due to the adoption of a heating resistance wire, the heating temperature is up to 300 DEG C, resistance wire easily due to the high temperature ageing and burned, commonly used electric heating coil service life about in half a year or so. Therefore, maintenance workload is relatively large. 2 electromagnetic heater advantages and characteristics of A. energy saving effect compared to the original resistance wire heating coil power saving effect is more than 30%, relatively different raw materials, production of different products, the power saving effect has changed. But in the products that have been used in power saving efficiency is up to 75%. B. environmental protection effect is good can significantly reduce the environmental temperature. C. service life is long, the temperature is only 100 degrees Celsius, there is no question of the heating coil replacement. Compared with the original resistance wire heating reduces the input of two times. D. can improve the product yield due to the high heating efficiency of the product, can significantly reduce the heating time, improve product yield.
