Description

Technical Field

[0001] The utility model relates to the technical field of horizontal superconducting magnetic separation equipment, in particular to a segmented separation system for a superconducting magnetic separator. Background Art

[0002] At present, in order to meet the actual needs of reciprocating motion and sorting, the sorting system of the horizontal superconducting magnetic separator usually includes a long outer cylinder, an intermediate dead cavity is arranged in the middle of the outer cylinder, effective cavities are arranged at both ends of the intermediate dead cavity, and side dead cavities are arranged outside the effective cavity; the intermediate dead cavity, the effective cavity and the side dead cavity are all separated from the outer cylinder and need to be installed inside the outer cylinder in sequence; the middle dead cavity is filled with magnetic balance medium, and the effective cavity is filled with magnetic conductive sorting medium; when the sorting system is working, the effective cavity is the working unit of magnetic sorting, and the magnetic material is captured when the slurry passes through the effective cavity. The effective cavities on both sides of the middle dead cavity alternately enter and exit the magnetic field for sorting and washing respectively.

[0003] The sorting system of the horizontal superconducting magnetic separator has high requirements for water tightness, so it has high requirements for the processing accuracy of each component. However, due to the long length of the outer cylinder and the fact that both the effective cavity and the intermediate ineffective cavity are complex barrel-type medium box series structures, the processing difficulty and cost of the entire sorting system are relatively large. At the same time, there are assembly gaps between the medium boxes in the intermediate ineffective cavity and between the intermediate ineffective cavity and the outer cylinder, which inevitably causes the problem of slurry cross-linking between the ore dressing side and the flushing side, resulting in a decrease in the grade of the concentrate. At the same time, the slurry entering the intermediate ineffective cavity will also corrode the magnetic balance medium inside it, affecting the magnetic balance of the sorting system.

[0004] Therefore, the research and development of a superconducting magnetic separator segment separation system that can effectively reduce the processing difficulty and cost and avoid the problems of slurry cross-linking and magnetic balance medium corrosion is an issue that needs to be urgently addressed at this stage. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the utility model provides a segmented sorting system for a superconducting magnetic separator, which divides a long outer cylinder into three sections (side section, middle section, and side section), thereby reducing the processing difficulty of the outer cylinder itself, providing a wider selection of processing raw materials and processing equipment, and reducing the processing cost; at the same time, the middle ineffective cavity and the effective cavity can be more conveniently installed in the outer cylinder, and the middle ineffective cavity can also be conveniently sealed and connected to the inner wall of the middle section, so that the problems of slurry cross-talk and magnetic balance medium corrosion will no longer occur, thereby effectively improving the concentrate grade and service life.
