Steel cord belt induction heating device

Abstract

The invention relates to an induction heating device, in particular to the induction heating device for a steel wire rope core belt. A first heating magnet (1-1), a second heating magnet (1-2) and a third heating magnet (1-3) of the device are evenly fixed under three evenly-distributed through holes in the lower surface of a stainless steel support (4). The two ends of a coil of the first heating magnet, the two ends of a coil of the second heating magnet and the two ends of a coil of the third heating magnet are connected with the output end of a first controlled variable-frequency power source (2-1), the output end of a second controlled variable-frequency power source (2-2) and the output end of a third controlled variable-frequency power source (2-3) respectively. Power supply of the coil of the first heating magnet, the coil of the second heating magnet and the coil of the third heating magnet is controlled by a temperature monitor (5). A first temperature sensor (3-1), a second temperature sensor (3-2) and a third temperature sensor (3-3) are evenly mounted under three temperature sensor through holes in the lower surface of the stainless steel support, are all connected with the temperature monitor and can monitor the temperature of the steel wire rope core belt which is heated by the first heating magnet, the second heating magnet and the third heating magnet. The induction heating device is low in manufacturing cost, high in temperature rising speed, high and controllable in temperature, convenient to maintain, and capable of solving the problems that the surface of a raw coal lifting belt is frozen in cold weather, and the belt is cracked.

Description

technical field [0001] The invention relates to a steel cord belt induction heating device, in particular to an induction heating device suitable for a steel cord belt in a raw coal lifting and transporting center. Background technique [0002] The steel cord belt for raw coal transportation is in a low temperature working environment. Due to the cold weather, the surface of the steel cord belt is frozen. When the coal slides onto the steel cord belt, the impact force will crack the steel cord belt with ice, and the normal operation of the steel cord belt cannot be guaranteed. run. Contents of the invention [0003] The technical problem to be solved by the present invention is that when the surface of the steel cord belt for raw coal is frozen when the steel cord belt is frozen in cold weather, the impact force when the coal slides onto the steel cord belt will crack the steel cord belt with ice, so as to ensure that the steel cord belt normal operation of the core belt....
