Description

A high-efficiency energy-saving liquid circulation electromagnetic heater

technical field

The utility model relates to the field of electromagnetic heaters.

Background technique

The existing liquid electromagnetic heater is mainly composed of a metal barrel and a group of induction wires. The induction wire is wound on the bracket outside the metal barrel. When working, the induction wire conducts electricity to make the metal barrel generate heat and heat the liquid in the metal barrel. , if the liquid is to be heated to a high temperature of 400-600°C, multiple liquid electromagnetic heaters need to be connected in series and heated step by step. The disadvantage is that the heating effect is not good enough, and multiple liquid electromagnetic heaters occupy The workshop area is large.

Utility model content

The purpose of this utility model is to provide an environment-friendly and energy-saving liquid electromagnetic heater for the insufficient heating effect of the existing liquid electromagnetic heater and the large workshop area.

The utility model is composed of a barrel body, a thermal insulation layer, and a group of pipeline electromagnetic heating devices. A group of pipeline electromagnetic heating devices are installed in the barrel body in a circular distribution. The thermal insulation layer is wrapped outside the barrel body. The upper part is equipped with a discharge port, and the top is equipped with a maintenance manhole; the pipeline electromagnetic heating device is composed of a metal tube, a non-conductive induction line tube, an induction line, and a heat insulation sleeve. Inside the heat shield, the sense wire is wrapped around a non-conductive sense wire tube. There is an expansion joint in the barrel. There are cooling holes on the non-conductive induction pipe. The barrel body is also equipped with a pressure gauge and a safety valve, and a discharge valve is provided at the bottom of the barrel body.

The advantages of the invention are: since a group of electromagnetic heaters are arranged in the barrel, the liquid in the barrel can be heated to 400-600°C at one time, so the heating effect is good, the efficiency is high, the heater is small in size, and occupies a small workshop area.
