High-gradient internal circulation oil cooling iron remover

Abstract

The invention relates to a high-gradient internal circulation oil cooling iron remover, which comprises a magnetic coil (4), an internal circulation oil path system (3), an external cooling system (2) and an oil conservator (1), wherein the magnetic coil (4) is used for generating an excitation magnetic field capable of realizing the iron absorption effect of the iron remover; the magnetic circuit of the magnetic coil (4) is an opened magnetic circuit structure; the internal circulation oil path system (3) is used for distributing, collecting and circulating oil of a transformer; the external cooling system (2) is used for dissipating heat of the oil of the transformer so as to realize internal heat dissipation balance of the high-gradient internal circulation oil cooling iron remover; and the oil conservator (1) is used as a complementary container when oil in the transformer is inflated in the event of operating equipment. By adopting the internal circulation structure, the high-gradient internal circulation oil cooling iron remover disclosed by the invention is capable of simplifying external circulation pipelines, reducing oil path circulation resistance, avoiding the problems of being complex and interferential in oil path arrangement, low in circulation efficiency, leaked in welding spot and the like, ensuring the iron remover to work normally, and increasing the iron removing efficiency.

Description

technical field [0001] The invention relates to the field of magnetic mineral processing machinery, in particular to the technical field of iron removers, in particular to a high-gradient internal circulation oil-cooled iron remover. Background technique [0002] In magnetic beneficiation, the iron remover is widely used. The iron remover is not only suitable for the coal conveying system of the power plant, but also suitable for the units and places that need to separate ferromagnetic substances such as ore dressing plants, sugar factories, and ceramic factories. For example, in the Chinese patent application No. 9622344.3 No. 1 discloses a box-type iron remover that utilizes the suction force of permanent magnets to absorb ferromagnetic substances in materials. It includes I-shaped rails, electric trolleys and boxes. Its main feature is that permanent magnets are installed in the box. , the upper part of the box is equipped with a main motor, worm gear, and worm drive mech...

AI Technical Summary

Problems solved by technology

At present, the commonly used circulating oil-cooled iron remover is an external circulation structure, and the design of the oil circuit has many bends, which interfere with each other, making it difficult to arrange.
