Energy-saving electromagnetic heating controller

Abstract

An energy-saving electromagnetic heating controller relates to the technical field of heating devices and is characterized by comprising a main board unit, a control unit connected with the main board unit, a display unit and an auxiliary unit, wherein the display unit and the auxiliary unit are connected with the control unit in parallel. The energy-saving electromagnetic heating controller is simple in structure, convenient to control and capable of enabling a heating device to be good in energy-saving effect, saves electricity by more than 30% compared with an original resistance wire heating ring, is good in environment-protection effect, capable of remarkably reducing indoor working environment temperature, long in service life and capable of enabling operation temperature of a heating ring to be around 100 DEG C, does not have a problem of changing the heating ring, and reduces secondary investment compared with heating of the original resistance wire.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to an energy-saving electromagnetic heating controller. Background technique [0002] At present, electric heating is widely used in industrial production, and more than 90% of them use resistance wire heating. This heating method mainly relies on contact conduction to transfer heat energy. Various heating devices made of resistance wire Plates, rings, only the heat that is close to the inside of the surface of the barrel can be transferred to the barrel. [0003] There are following disadvantages in this traditional heating device: [0004] (1) Large heat loss: the heating method adopted by the existing enterprises is wound by resistance wire, the inner and outer sides of the ring generate heat, and the heat on the inner surface (close to the barrel part) is conducted to the barrel, while the outer heat is large Part of it is lost to the air, resulting in the loss and waste of el...

AI Technical Summary

Problems solved by technology

[0004] (1) Large heat loss: The heating method adopted by the existing enterprises is wound by resistance wire, the inner and outer sides of the ring generate heat, and the heat on the inner surface (close to the barrel part) is conducted to the barrel, while the outer heat is large Part of it is lost to the air, resulting in the loss and waste of electric energy

[0005] (2) Ambient temperature rise: due to a large amount of heat loss, the ambient temperature rises, especially in summer, which has a great impact on the production environment. The on-site working temperature exceeds 45°C. Some enterprises have to use air conditioners to reduce the temperature, which in turn causes energy consumption. secondary waste

[0006] (3) Short service life and large amount of maintenance: due to the use of resistance wire for heating, its heating temperature is as high as about 800°C, and the resistance wire is easy to burn out due to high temperature aging. The service life of commonly used electric heating coils is about half a year. Therefore, maintenance work Relatively large amount

[0007] In addition, the traditional point heating device also has the characteristics of slow temperature rise, resulting in low work efficiency, and the resistance wire heating has a disadvantage of low power density, which cannot be adapted to some heating occasions that require higher temperature
