Abstract
A high-gradient internal-circulating oil-cooled Magnetic Separator, includes magnetic system coils, an internal-circulating oil path system, an external-cooling system and an oil conservator. The magnetic system coils are used for generating excitation magnetic field to achieve the iron-absorption function, the magnetic paths of the magnetic system coils being an open magnetic path structure. The internal-circulating oil path system is used for allocation and collection circulation of transformer oil. The external-cooling system is used for heat dissipation of transformer oil to achieve internal heat dissipation balance. The oil conservator is used as a supplementary container for the transformer oil expansion during the apparatus's operation. An internal-circulating structure is employed, and external-circulating pipes are simplified, circulating resistance in oil paths being reduced, problems including complex interference in oil paths arrangement, low circulation efficiency, leakage at welding spots, etc. being avoided, ensuring normal operation, and enhancing efficiency of iron removing.
