Magnetic shielding tube-type electromagnetic induction heating device

Abstract

The invention discloses a magnetic shielding tube-type electromagnetic induction heating device, which comprises an electromagnetic induction heating packet and a temperature sensor. The magnetic shielding tube-type electromagnetic induction heating device is characterized in that the electromagnetic induction heating packet comprises a protective shell, a high-frequency electromagnetic induction body and a thermal insulation layer; the electromagnetic induction heating packet surrounds and wraps the outer surface of a charging barrel; the charging barrel is made of a conductive material; and the high-frequency electromagnetic induction body is in a retractable tubular structure. According to the magnetic shielding tube-type electromagnetic induction heating device, the problems that the electromagnetic induction heating device in the prior art is high in energy consumption, low in efficiency and high in environment temperature, and has potential safety hazards; the control accuracy on the temperature cannot reach the technological requirements; and normal operation of surrounding equipment is affected or a human body is injured by electromagnetic leakage are effectively solved, so that the magnetic shielding tube-type electromagnetic induction heating device is efficient, energy-saving, low in operation cost, low in maintenance amount, moderate and comfortable in working environment temperature, little in external electromagnetic leakage, free of electromagnetic pollution to surroundings, and environment-friendly; and the control accuracy on the temperature can reach 1 DEG C.

Description

Technical field [0001] The invention relates to the technical field of fluid heating in conductor pipelines, plastic heating in steel cylinders or heating and smelting of low-melting conductive materials, in particular to a magnetic shield tube electromagnetic induction heating device. Background technique [0002] At present, in high-cold areas, steel pipe oil pipelines in the field, especially for heavy oil transportation, even though there is an insulation layer outside the pipelines, pipeline blockages often occur due to freezing. In plastics and other industries, due to the needs of injection molding or extrusion processes, plastic raw materials need to be heated from a low temperature within a limited length of the steel barrel to a high temperature that meets the requirements of the injection molding or extrusion process to complete the injection at the end nozzle. Nowadays, the commonly used technical method is to use heating resistance wire wrapping heating or ceramic in...
