Pipe electromagnetism heating device and electromagnetism heating method

Abstract

The invention relates to a pipe electromagnetism heating device and an electromagnetism heating method. The pipe electromagnetism heating device is characterized in that a main heating tube and a center heating tube which are made of magnetic materials are adopted; and a plurality of groups of heating coils are wound at the periphery of the main heating tube at certain intervals, each group of heating coil is respectively connected with an electromagnetic controller used for providing high-frequency current, the two ends of the centre heating tube are sealed and fixedly arranged in the main heating tube, the central axis of the centre heating tube coincides with that of the main heating tube, and a layer of a metal flow-obstructing wire is wound at the periphery of the centre heating tube. Materials to be heated flow into a space between the main heating tube and the centre heating tube, the groups of heater coils are energized, the main heating tube and the central heating tube heat up simultaneously, and the materials to be heated flow between the main heating tube and the centre heating tube and are heated quickly and thoroughly. The pipe electromagnetism heating device can rapidly heat up the material flowing between the main heating pipe and the centre heating pipe based on the principle of electromagnetism heating and by being combined with a reasonable piping, and is simple in structure, easy to manufacture, install and replace, and applicable to the heating of liquid and solid-liquid mixtures.

Description

technical field [0001] The invention relates to a heating device and a heating method, in particular to a pipeline electromagnetic heating device and an electromagnetic heating method. Background technique [0002] At present, electromagnetic heating is widely used in households and less in industrial applications. It is mainly used in plastic film blowing machines, wire drawing machines, injection molding machines, granulators, rubber extruders, vulcanizers, and cable production extruders. On, but less application in pipeline heating. It is understood that pipeline heating technology is mainly used to heat oil and water, and because there is no central tube, the heating area is greatly reduced, and the heating power is small; it is easy to form laminar flow, so the heating effect is poor. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a pipeline electromagnetic heating device and electromagnetic heating...
