Description

Technical Field

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

[0002] With white corundum as raw material, it is made by melting industrial alumina powder at a temperature of more than 2000 degrees in an arc and then cooling. It is crushed and shaped, magnetically separated to remove iron, and screened into various particle sizes. It has a dense texture, high hardness, and sharp corners. It is suitable for manufacturing ceramics, resin-bonded abrasives, grinding, polishing, sandblasting, precision casting (special corundum for precision casting), etc. It can also be used to manufacture advanced refractory materials without affecting the color of the processed parts; it can be used in processes where iron powder residue is strictly prohibited; the amount of iron oxide is extremely low, which is suitable for sandblasting operations where iron residue is strictly prohibited; it has the advantages of fast processing speed and high quality. Since most of the equipment used to produce white corundum particle products is currently Barmac crushing and processing, due to the high strength and hardness of sintered white corundum mature balls, the wear-resistant body and chute plate inside Barmac are severely worn, and the wear-resistant body and chute plate in Barmac are basically made of iron or steel, so a large amount of magnetic iron enters the white corundum particle products, causing a large quality risk to white corundum products.

[0003] The utility model with announcement number CN211937376U discloses a deironing device for white corundum production, which relates to the technical field of deironing of production raw materials, and specifically includes a base, the upper surface of the base is fixedly connected with a shell, a feeding port is provided on one side of the inner top wall of the shell, a vibration drawing hole is provided on one side of the inner side wall of the shell, an electromagnetic needle plate is connected to the inner drawing of the vibration drawing hole, a piston mechanism is fixedly installed on one side of the outer surface of the shell, a motor box is fixedly connected on one side of the outer surface of the shell, a sieve plate hole is provided on the lower part of one side of the inner side wall of the shell, and an electromagnet block is fixedly connected on one side of the inner side wall of the shell. The deironing device for white corundum production, through the setting of the electromagnetic needle plate, the densely arranged electromagnetic columns greatly increase the surface area for adsorbing iron impurities, and has a sufficient deironing effect. Through the coordinated setting of the motor box and the piston mechanism, the electromagnetic needle plate performs reciprocating vibration motion, and the white corundum raw material slides downward along the electromagnetic needle plate under the action of gravity, thereby achieving the purpose of avoiding blockage and enhancing the deironing effect. However, the technical solution of this patent has the following defects: although the iron impurities in the white corundum raw material powder can be removed by using the combination of electromagnetic needle plates, filter plates, electromagnet blocks and sieve plates, the iron impurities trapped on the electromagnetic needle plates, filter plates, electromagnet blocks and sieve plates cannot be easily removed. When a large amount of iron impurities are trapped on the electromagnetic needle plates, filter plates, electromagnet blocks and sieve plates, it is easy to cause the filter plates and sieve plates to become blocked, thereby affecting the filtering effect of the white corundum raw material powder. Therefore, the technical solution of this patent has the defect of easily affecting the filtering efficiency and filtering effect. Based on this, the present application proposes a raw material impurity removal device for corundum production, which can solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is realized through the following technical solutions: A device for removing impurities from raw materials used in corundum production, including a frame, which is linear.

The output end of the telescopic cylinder is rotatably installed with a ball, and the ball contacts the top surface of the turntable. By using this structure, the lifting of the turntable can be realized, and the ball can reduce the wear between components. Brief Description of the Drawings

A spline shaft 9 driven by a motor 6 to rotate is installed above the frame 1. The spline shaft 9 is located directly above the blanking space. A turntable 2 that can reciprocate up and down is installed outside the spline shaft 9. Two fixed plates 14 are installed on the periphery of the turntable 2, and electromagnet components 3 are installed between the four groups of fixed plates 14. A blanking plate 13 is installed below the blanking space, and the blanking plate 13 is inclined downward and faces the raw material conveyor belt 4.

[0022] As an alternative technical solution of the present utility model, two electric rollers 12 are installed on both sides inside the frame 1. The raw material conveyor belt 4 and the miscellaneous material conveyor belt 5 are respectively sleeved on the two sets of electric rollers 12. When installing the two conveyor belts, they need to be tightened. Moreover, the structure of the electric roller 12 is compact, but the cost is relatively high. In actual application, the electric roller 12 can be replaced by a roller driven by a servo motor.

[0023] As an alternative technical solution of the present utility model, a mounting plate 11 is installed on one side of the frame 1 close to the top surface of the miscellaneous material conveyor belt 5, which is flush with the top surface of the frame 1.

After the telescopic cylinder 7 contracts, the turntable 2 can be reset under the action of the spring 10, and the use of the rotating balls 8 can reduce the wear between components and ensure smooth rotation of the turntable 2.

[0026] In summary, the features, assembly methods, usage processes, and functions achieved by the various components in the present utility model are as follows: The linear frame 1 serves as the main body of the device.

A turntable 2 that can move up and down reciprocally is installed on the spline shaft 9. Two fixing plates 14 are installed on the outer periphery of the turntable 2. Electromagnet components 3 are installed between the four groups of fixing plates 14. As the four electromagnet components 3 rotate and move up and down, the iron slag doped in the raw materials can be continuously sucked out, transported to the miscellaneous material conveyor belt 5, and sent out, enabling the entire device to meet the actual usage needs and having a relatively high working efficiency. Below the blanking space, a blanking plate 13 is installed, which is inclined downward and faces the raw material conveyor belt 4 to facilitate the collection of the raw materials after impurity removal, facilitating subsequent centralized processing and use. A spring 10 is sleeved on the spline shaft 9. Above the frame 1, a telescopic cylinder 7 is installed, and a rotating ball 8 is rotatably installed at its output end. The rotating ball 8 is in contact with the top surface of the turntable 2.
