Intelligent frequency conversion electromagnetic heating uninterruptible heating unit

Abstract

The invention provides an intelligent frequency conversion electromagnetic heating uninterrupted heating unit, which belongs to the technical field of electric heating. Including heating water tank, electromagnetic coil, electromagnetic heating components, intermediate frequency drive unit, centralized measurement and control module, etc. The electromagnetic coil is arranged between two adjacent heating water tanks, which effectively improves the utilization rate of the electromagnetic coil while separating water and electricity, and reduces electromagnetic radiation. The structure of the heating water tank combined with the electromagnetic heating component is convenient for production and installation, and can realize live inspection and maintenance. The centralized measurement and control module and the intermediate frequency drive unit constitute the multi-group drive of the electromagnetic coil and the two-level control mode, which realizes high fault-tolerant control and uninterrupted operation of the heating process. Combined with the joint temperature sensor, it effectively guarantees continuity and reliability. In addition, it has the advantages of low production cost, simple process, convenient capacity expansion, small size, low operating cost, remarkable energy saving effect, safety and reliability, etc. It can be widely used in various electric heating occasions, effectively improving the effect of energy saving and environmental protection.

Description

technical field [0001] The invention relates to an electromagnetic heating unit, in particular to an uninterrupted high-power electromagnetic heating unit controlled by intelligent frequency conversion. It belongs to the technical field of electric heating. Background technique [0002] The principle of electromagnetic intermediate frequency heating is very mature at present, and two main methods are generally used in application. One is to wind the electromagnetic coil on the heated body, and the other is to place the heated body on the side of the disc electromagnetic coil. Their common feature is that compared with the heating coil, they are all used on one side, and the device is larger in size; the other side needs to be equipped with a magnetic conductive material and a heat insulating layer, which has a certain amount of heat loss and will cause more electromagnetic radiation. Each power model is independently designed and manufactured, the production process is comp...
