High-gradient internal circulation oil cooling iron remover

Abstract

The invention discloses a high-gradient internal circulation oil cooling iron remover which comprises a magnetic system coil (4), an internal circulation oil path system (3), an external cooling system (2) and an expansion tank (1), wherein the magnetic system coil (4) is used for generating an excitation magnetic field which realizes the iron sucking function of the iron remover; the magnetic path of the magnetic system coil (4) is in an opened magnetic path structure; the internal circulation oil path system (3) is used for distributing, collecting and circulating transformer oil; the external cooling system (2) is used for radiating the heat of the transformer oil so as to realize the heat radiation balance in the high-gradient internal circulation oil cooling iron remover; and the expansion tank (1) is used as a compensation container for the transformer oil expansion when equipment operates. By adopting the internal circulation structure, the external circulation pipeline is simplified, the oil path circulation resistance is reduced, problems that an oil path is complexly arranged with interference, the circulation efficiency is low, a welding spot has leakage and the like are avoided, the normal operation of the iron remover is ensured, and the iron removing efficiency is improved.

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.
