Vertical permanent magnet heating device

Abstract

The invention discloses a vertical permanent magnet heating device capable of increasing the relative rotating speed between a conductor and magnets. The vertical permanent magnet heating device comprises a vertically arranged magnet installation column and a plurality of magnets embedded on the magnet installation column. The vertical permanent magnet heating device further comprises an iron tube with which the magnet installation column is sleeved, and the magnet installation column is connected with a motor through a rotating shaft. A driving gear is further arranged on the rotating shaft, an inner driven gear is arranged on the inner wall of the iron tube, and planetary gears meshed with the driving gear and the inner driven gear at the same time are further arranged between the driving gear and the inner driven gear. According to the vertical permanent magnet heating device, the iron tube rotates in a reverse mode at the same time when the motor drives the magnet installation column to rotate forwardly through a linkage mechanism formed by the driving gear, the inner driven gear and the planetary gears, so that the relative rotating speed between the iron tube and the magnet installation column is greatly increased, the efficiency of cutting a magnetic force line is increased, and the heat energy generating efficiency is effectively increased.

Description

technical field [0001] The invention relates to the field of electromagnetic applications, in particular to a vertical permanent magnet heating device. Background technique [0002] The closed iron core (or a large piece of conductor) is in an alternating magnetic field, and the alternating magnetic flux causes an induced current in the closed iron core (or a large piece of conductor), forming an eddy current. If the iron core (or conductor) is pure iron (pure metal), the eddy current generated is very large due to the small resistance, and the heating effect of the current can be that the temperature of the iron (or metal) reaches a very high level, or even the iron (or metal) or metal) to melt iron. This phenomenon is called the eddy current effect. [0003] At present, people begin to utilize the eddy current effect, for example, CN102778040A designs a magnetic heating device. Generally, the amount of heat energy generated is related to the frequency at which the condu...

Problems solved by technology

The heating device in the prior art is nothing more than the rotation of the conductor or the rotation of the magnet. Without increasing the motor speed, and without increasing the motor so that the conductor and the magnet rotate in opposite directions at the same time, it is impossible to improve the conductor cutting magnetic force line.
