Description

Technical Field

[0001] The utility model relates to the field of electromagnetic iron removers, in particular to an electromagnetic iron remover with a changed heat dissipation mode. Background Art

[0002] Electromagnetic iron remover is a device that uses magnetic field attraction to remove ferromagnetic impurities from material conveyor belts. This device will have the following functions in the production process: first, it protects the conveyor belt from damage by ferromagnetic impurities; second, it ensures the safe and stable operation of subsequent important equipment, such as crushers, grinders, boilers, etc.; third, it ensures or improves the quality of related products, such as ceramic products, because ferromagnetic impurities in production will seriously affect the color of the ceramic surface; fourth, it improves the quality of port material transportation to meet customer requirements;

[0003] The electromagnetic iron remover widely used at present is powered on for a long time, and the biggest problem is heat dissipation. The existing electromagnetic iron removers are mainly divided into three types according to the cooling method: self-cooling, oil-cooling, and forced air-cooling. The oil-cooling electromagnetic iron remover refers to immersing the coil of the electromagnetic iron remover in transformer oil, and using the flow of transformer oil to take away the heat generated by the coil. This cooling method needs to consider the flow path and insulation seal of the transformer oil, making the structure of the electromagnetic iron remover very complicated; the forced air-cooling electromagnetic iron remover uses a fan to blow away the heat generated by the coil, which also requires complex installation; and for the self-cooling electromagnetic iron remover, the existing technology reduces the heat generation by reducing the current per unit area of ​​the electromagnetic wire, but because the coil is in a long-term operation state, even if the current is reduced, there is always a high temperature rise inside the coil, which keeps the coil in a high temperature state for a long time, affecting the life of the coil and not conducive to the full play of the magnetic properties of the electromagnetic iron remover;

[0004] To this end, it is necessary to adjust the heat dissipation method of the electromagnetic iron remover to greatly reduce the internal temperature of the electromagnetic coil and perform efficient heat dissipation. At the same time, additional heat dissipation methods should be added to significantly improve the overall heat dissipation effect of the electromagnetic iron remover. Utility Model Content
