Electromagnetic induction heating cylinder

Abstract

The invention discloses an electromagnetic induction heating cylinder. A thermal insulation layer coats outside the cylinder; an epoxy resin board layer coats outside the thermal insulation layer; an electromagnetic heating coil winds the outer side of the epoxy resin board layer; the thermal insulation layer is insulated cotton; the insulated cotton is tightened and fixed on the periphery of the cylinder through a high-temperature-resistant ribbon; and the epoxy resin board layer is tightened and fixed on the periphery of the thermal insulation layer through the high-temperature-resistant ribbon. According to the electromagnetic induction heating cylinder, a metal cylinder is self-heated through the electromagnetic induction principle; and a thermal insulating material with a certain thickness can coat outside the cylinder according to the specific circumstance, so that the heat loss is greatly reduced; and the thermal efficiency is improved. Therefore, the electricity-saving effect is very significant and can reach 30%-75%.

Description

technical field [0001] The invention relates to a barrel, in particular to an electromagnetic induction heating barrel. Background technique [0002] At present, the traditionally used resistive heating elements such as electric heaters and electric heating coils are heated by heat conduction, which has the problem of low efficiency. This kind of heat conduction method is a heating method that converts electrical energy into magnetic energy, so that the heated steel body induces magnetic energy and generates heat. Heating must transfer heat energy through contact. Both heating and cooling have inertial phenomena, and the heating and cooling are slow; the heating ring has a large loss and a short life. In addition, another disadvantage of resistance wire heating is that the power density is low, and it cannot be adapted to some heating occasions that require higher temperatures. For example: use the electric heating coil to heat, and transfer the heat to the barrel through ...

Problems solved by technology

Only the heat close to the inner side of the barrel surface can be transferred to the barrel, so that most of the outer heat is lost to the air, there is a heat conduction loss, and the ambient temperature rises
