[0002] Sintered corundum refers to refractory clinker made from calcined alumina as raw material, which is ground into pellets or green bodies and sintered at a high temperature of 1750 - 1900 °C. Its purity is slightly lower than that of tabular corundum, and it has the advantages of large bulk density, low porosity, high grain strength, excellent thermal shock resistance and slag erosion resistance at high temperatures. The production process of sintered corundum mainly includes crushing of raw materials, magnetic separation for iron removal, fine grinding and classification, and then mixing, forming, drying and sintering.
[0003] Among them, magnetic separation for iron removal is a process of using magnetic separation equipment to remove metal impurities such as iron in the raw materials, and it is an important step to improve the purity and quality of products. Existing magnetic separation equipment mostly uses plate - type magnetic separators. The plate - type magnetic separator has the advantage of large processing capacity. However, when this magnetic separator is working, the material and magnetic impurities are in a relatively static state on the conveyor belt, resulting in incomplete suction of iron impurities in the material.

[0007] Preferably, the magnetic separation leaf and the tipping plate are arranged in a "V" shape, and the included angle between the magnetic separation leaf and the tipping plate is 135°. At the same time, the distances between adjacent two groups of magnetic separation leaves are the same.
[0008] Preferably, the fixed column and the scraper are arranged in parallel, and the cross - section of the fixed column is circular. At the same time, four groups of inner connecting bars and outer connecting bars are respectively installed on the fixed column.

[0011] Preferably, the stirring shaft is driven to rotate by a reduction motor, and a discharge pipe is installed at the bottom of the magnetic separation cylinder.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4 , the present utility model provides a magnetic separation device for the production of sintered corundum, including a magnetic separation cylinder 1. A stirring shaft 2 is movably installed inside the magnetic separation cylinder 1, and a fixed cylinder 3 is fixedly installed on the outer side of the stirring shaft 2. At the same time, a connecting seat 4 is fixedly welded on the outer surface of the fixed cylinder 3, and a magnetic separation leaf 5 is fixedly installed on the outer surface of the connecting seat 4. A tipping plate 51 is fixedly installed at one end of the magnetic separation leaf 5 away from the connecting seat 4; a scraping plate 11 covers the inner wall surface of the magnetic separation cylinder 1, and a connecting plate 10 is fixedly installed on the back surface of the scraping plate 11. At the same time, a fixed column 6 is fixedly installed at one end of the connecting plate 10 away from the scraping plate 11.
[0022] Working principle: When in use, the stirring shaft 2 inside the magnetic separation cylinder 1 rotates, so that the stirring shaft 2 drives a plurality of magnetic separation leaves 5 on its outer side to rotate. The magnetic separation leaves 5 can adsorb metal particles in the material. Through the plurality of magnetic separation leaves 5 during the rotation process, the contact area between the material and the plurality of magnetic separation leaves 5 can be increased, and the adsorption effect on the metal particles in the material can be improved.
[0023] As a preferred embodiment, five connecting seats 4 are evenly installed on the outer surface of the fixed cylinder 3, and the angles between adjacent two connecting seats 4 are the same. At the same time, four magnetic separation leaves 5 are evenly arranged on the outer side of the connecting seat 4.
[0024] The magnetic separation leaf 5 and the tipping plate 51 are arranged in a "V" shape, and the included angle between the magnetic separation leaf 5 and the tipping plate 51 is 135°. At the same time, the distances between adjacent two magnetic separation leaves 5 are the same.
[0025] The magnetic separation leaf 5 and the tipping plate 51 are arranged in a "V" shape. When stirring the material, a unique flow pattern can be formed, enabling the material to be mixed more evenly in the stirring container faster; the V-shaped stirring leaf can generate stronger shear force and impact force during the stirring process; this helps to break the agglomerates in the material, enabling the metal particles wrapped inside the agglomerates to come into contact with the magnetic separation leaf 5 and can be adsorbed by the magnetic separation leaf 5.
[0026] As a preferred embodiment, the fixed column 6 and the scraping plate 11 are arranged in parallel, and the cross-section of the fixed column 6 is circular. At the same time, four inner connecting strips 7 and outer connecting strips 8 are respectively installed on the fixed column 6.
[0027] As a preferred embodiment, the ends of the inner connecting strip 7 and the outer connecting strip 8 are fixedly arranged on the inner wall of the magnetic separation blade 5, and both the inner connecting strip 7 and the outer connecting strip 8 are arc-shaped structures made of metal materials.
[0028] The fixing column 6 fixedly connects the scraping plate 11 through the connecting plate 10, and both sides of the connecting plate 10 are provided with slots 101. At the same time, the cross-section of the slot 101 is an isosceles trapezoid structure, and a plurality of groups of through holes 9 are evenly arranged on the surface of the connecting plate 10.
[0029] As a preferred embodiment, the stirring shaft 2 is driven to rotate by a reduction motor, and a discharge pipe is installed at the bottom of the magnetic separation cylinder 1.
[0030] When the stirring shaft 2 rotates, the scraping plate 11 can be driven to rotate through the fixing column 6 and the connecting plate 10, so that the scraping plate 11 can scrape the materials adhered to the inner wall of the magnetic separation cylinder 1. Without wasting raw materials, there is no need to clean the materials adhered to the inner wall of the magnetic separation cylinder 1 later.
