Description

Technical Field

[0001] The utility model relates to the technical field of dense corundum production, in particular to a raw material magnetic separation device for dense corundum production. Background Art

[0002] Dense corundum is a new type of high-purity refractory raw material made by melting high-purity alumina and a reducing agent in a certain ratio in an electric arc furnace and then cooling them. Dense corundum has good acid and alkali resistance, good wear resistance, corrosion resistance and volume stability at high temperatures, and is widely used in the steel metallurgy, petrochemical industry, building materials and ceramics industries. Magnetic separation is the process of separating magnetic substances from the material by utilizing the attraction of a magnetic field to the magnetic substances in the material. In the production of dense corundum, magnetic separation can effectively remove ferromagnetic impurities such as iron filings and iron oxides from the raw materials, thereby avoiding affecting the performance and quality of the dense corundum. However, existing magnetic separation devices are prone to accumulation of dense corundum raw materials due to uneven feeding, resulting in low magnetic separation efficiency and poor separation effect. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing magnetic separation device is prone to accumulation of dense corundum raw materials due to uneven feeding, resulting in low magnetic separation efficiency and poor separation effect.

[0004] In order to solve the above problems, the utility model provides a magnetic separation device for raw materials for dense corundum production. A feed port is provided on one side of the magnetic separator, a conveyor belt is provided above the feed port, baffles are provided on both sides of the conveyor belt, a hopper is provided above the conveyor belt, a plurality of slide bars are provided at intervals on the baffle along the conveying direction of the conveyor belt, a plurality of dispersion blocks are provided at intervals on the lower side of the slide bars along the length direction thereof, the dispersion blocks on adjacent slide bars are staggered, and diamond-shaped protrusions are formed on the lower side of the dispersion blocks.

[0005] The raw material magnetic separation device for dense corundum production provided by the utility model also has the following technical features:

[0006] The baffle is provided with a slide cylinder, and the slide rod slides accordingly along the slide cylinder; one of the baffles is provided with a mounting plate, and an electric push rod is provided on the mounting plate, and the output end of the electric push rod is connected to the end of one of the slide rods; a gear is rotatably provided on the mounting plate, and the gear is arranged between adjacent slide rods, and teeth meshing with the gear are provided on the opposite side of the adjacent slide rods.

[0007] The cross sections of the sliding rod and the sliding cylinder are mutually matching squares.

[0010] The magnetic separator and the baffle are both provided with supporting legs.

[0011] The utility model has the following beneficial effects: dense corundum raw materials fall from a hopper onto a conveyor belt and pass through multiple rows of staggered and mutually coordinated dispersion blocks in turn. The dense corundum raw materials slide along the diamond-shaped protrusions on the lower sides of the dispersion blocks, so that the dense corundum raw materials are flattened by the dispersion blocks while being dispersed and then gathered.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0016] like Figures 1 to 3 As shown, the utility model is a raw material magnetic separation device for dense corundum production, a feed port 11 is provided on one side of the magnetic separator 10, a conveyor belt 12 is provided above the feed port 11, baffles 13 are provided on both sides of the conveyor belt 12, a hopper 21 is provided above the conveyor belt 12, a plurality of slide bars 22 are provided on the baffle 13 at intervals along the conveying direction of the conveyor belt 12, a plurality of dispersion blocks 23 are provided on the lower side of the slide bars 22 at intervals along the length direction thereof, the dispersion blocks 23 on adjacent slide bars 22 are staggered, and diamond-shaped protrusions 24 are formed on the lower side of the dispersion blocks 23.

[0017] The dense corundum raw material falls from the hopper 21 onto the conveyor belt 12, and passes through multiple rows of staggered and mutually coordinated dispersion blocks 23 in turn. The dense corundum raw material slides along the diamond-shaped protrusions 24 on the lower side of the dispersion blocks 23, so that the dense corundum raw material is flattened by the dispersion blocks 23, first dispersed and then gathered, and this cycle is repeated many times to break up and mix the dense corundum raw material, thereby achieving uniform feeding to the magnetic separator 10 and avoiding the accumulation of raw materials, thereby improving the magnetic separation efficiency and sorting effect.

[0018] Among them, the dispersed dense corundum raw material enters the magnetic separator 10 from the feed port 11 for magnetic separation process. The magnetic separator 10 is preferably a wet magnetic separator. Of course, other types of magnetic separators such as a drum roller magnetic separator and a semi-countercurrent magnetic separator can also be selected. The working principle of the wet magnetic separator is as follows: after the raw material is mixed with water, it enters the magnetic field area through the guide plate and enters the separation space from the bottom of the trough in a loose suspended state. The magnetic substance in the raw material is adsorbed by the surface of the magnetic roller. The rotation of the magnetic roller causes the magnetic substance to move to the weak magnetic field area, further causing the magnetic substance to separate from the magnetic roller and be collected, while the non-magnetic substance is not affected by the magnetic field and is washed by water to the mud discharge trough for discharge, thereby being able to separate the magnetic substance and non-magnetic substance in the dense corundum raw material. The working process of the magnetic separator 10 is a prior art and will not be described here.

[0019] Among them, see Figure 3 The diamond-shaped protrusion 24 is a pentahedral structure, the upper surface is a diamond, and the other four surfaces are located below the upper surface, so that the diamond-shaped protrusion 24 has the effect of breaking up and mixing the dense corundum raw material.

[0020] Preferably, see Figure 2 A slide 25 is provided on the baffle 13, and the slide rod 22 slides accordingly along the slide 25; a mounting plate 26 is provided on one of the baffles 13, and an electric push rod 27 is provided on the mounting plate 26, and the output end of the electric push rod 27 is connected to the end of one of the slide rods 22; a gear 28 is rotatably provided on the mounting plate 26, and the gear 28 is arranged between adjacent slide rods 22, and teeth 29 meshing with the gear 28 are provided on the opposite side of the adjacent slide rods 22.

[0021] The output end of the electric push rod 27 drives one of the slide rods 22 to slide back and forth along the slide cylinder 25, and the gear 28 engages with the teeth 29 accordingly, so that the two adjacent slide rods 22 can slide back and forth along the slide cylinder 25 in opposite directions and at equal distances, so that the dispersion blocks 23 on different slide rods 22 can move relative to each other, realizing an irregular breaking and mixing process of the dense corundum raw material, further improving the magnetic separation efficiency and sorting effect.

[0022] The number of slide bars 22 can be selected according to actual needs, preferably three, and the output end of the electric push rod 27 is connected to the end of the middle slide bar 22. The sum of the relative sliding strokes of adjacent slide bars 22 should be less than the spacing between adjacent dispersion blocks 23 on the same slide bar 22 to avoid motion interference.

[0023] Preferably, the cross-sections of the sliding rod 22 and the sliding cylinder 25 are mutually matching squares to prevent the sliding rod 22 from rotating around the sliding cylinder 25 .

[0024] Preferably, the upper side of the dispersion block 23 is rotatably connected to the slide rod 22 through a shaft 30, and a torsion spring 31 is provided on the shaft 30. The upper end of the torsion spring 31 is connected to the slide rod 22, and the lower end is connected to the upper side of the dispersion block 23, so that the dispersion block 23 can rotate around the shaft 30 under the push of the dense corundum raw material, so that the orientation angle of each dispersion block 23 is inconsistent, and it is reset under the action of the torsion spring 31, thereby realizing a more irregular dispersion and mixing process of the dense corundum raw material, further improving the magnetic separation efficiency and sorting effect.

[0025] Preferably, two conveying rollers 14 are disposed opposite to each other between the two baffles 13 , a motor 15 is disposed on one of the baffles 13 , and an output shaft of the motor 15 is connected to one of the conveying rollers 14 .

[0026] Preferably, the magnetic separator 10 and the baffle 13 are both provided with supporting legs 16 .

[0027] The working principle of this utility model is as follows:

[0028] The dense corundum raw material falls from the hopper 21 onto the conveyor belt 12, and at the same time, the output end of the electric push rod 27 drives one of the slide bars 22 to slide back and forth along the slide cylinder 25, and the gear 28 is meshed with the teeth 29, so that the two adjacent slide bars 22 can slide back and forth along the slide cylinder 25 in opposite and equidistant directions, so that the dispersion blocks 23 on different slide bars 22 can move relative to each other; at the same time, the dispersion blocks 23 can rotate around the shaft 30 under the pushing action of the dense corundum raw material, so that the orientation angles of each dispersion block 23 are inconsistent, so that the dense corundum raw material passes through the dispersion blocks 23 in turn and slides along the diamond-shaped protrusions 24 on the lower side of the dispersion blocks 23, so that the dense corundum raw material is flattened by the dispersion blocks 23, first dispersed and then gathered, and this cycle is repeated many times to perform an irregular breaking and mixing process on the dense corundum raw material, so as to achieve uniform feeding to the magnetic separator 10, avoid the accumulation of raw materials, and thus improve the magnetic separation efficiency and sorting effect.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
