Description

Technical Field

[0001] The invention relates to a plate-shaped dense brown corundum production device, belonging to the technical field of brown corundum production. Background Art

[0002] Brown corundum is a tan artificial corundum produced by melting and reducing bauxite, carbon material, and iron filings in an electric arc furnace. Brown corundum is smelted at high temperatures in an electric arc furnace using bauxite and coke (anthracite) as its primary raw materials. Grinding tools made from brown corundum are suitable for grinding high-tensile metals such as general-purpose steels, malleable cast iron, and hard bronze. It can also be used to manufacture high-grade refractory materials. Brown corundum features high purity, excellent crystallization, strong fluidity, low linear expansion coefficient, and corrosion resistance. Validated by dozens of refractory manufacturers, this product resists detonation, pulverization, and cracking during use. Its significantly higher cost-performance ratio than traditional brown corundum makes it an ideal aggregate and filler for brown corundum-based refractories.

[0003] However, in the prior art, after corundum is collected, the temperature of the corundum is lost quickly because the objects placed on it cannot effectively keep it warm, resulting in the occurrence of broken jade. Now, there is an urgent need for a plate-shaped dense brown corundum production device to solve the above problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a plate-shaped dense brown corundum production device to solve the problems raised in the above background technology. The present invention has good practicality and can slowly cool the corundum by utilizing the residual heat of the package, thereby avoiding the situation where the corundum breaks due to temperature loss.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: a plate-shaped dense brown corundum production device, including a ladle receiving car, the upper end of which is fixedly connected to a casting body, the upper end of which is fixedly connected to a limit tube, a ladle receiving body is provided in the limit tube, a ladle receiving body is provided at the upper end of the ladle receiving body, and a ladle receiving cover is provided, and a supporting steel frame is passed through and fixedly connected to the ladle receiving cover;

[0006] Two auxiliary connecting rods are fixedly connected to the circumferential surface of the connection body, silicon carbide bricks are fixedly connected to the circumferential inner wall of the connection body, graphite electrode bricks are fixedly connected to the lower inner wall of the connection body, and a mixture of brown corundum powder and phosphoric acid is smeared inside the connection body.

[0007] Furthermore, the four ends of the supporting steel frame are fixedly connected to limit blocks, and the connection cover and the casting body are filled with a mixture of brown corundum aggregate and high-lead cement.

[0008] Furthermore, a heat-insulating material is provided on the circumferential surface of the connecting body, and the upper end of the connecting body is a flat-end structure.

[0009] Furthermore, the connecting cover and the connecting body are cooperatively connected to each other.

[0010] Furthermore, the position limiting tube and the connecting body cooperate with each other.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1-Figure 5The present invention provides a technical solution: a plate-shaped dense brown corundum production device, including a receiving car 3, the upper end of the receiving car 3 is fixedly connected to a casting body 2, the upper end of the receiving car 3 is fixedly connected to a limiting tube 1, a receiving body 4 is arranged in the limiting tube 1, the upper end of the receiving body 4 is provided with a receiving cover 5, a supporting steel frame 6 is passed through and fixedly connected to the receiving cover 5, two auxiliary connecting rods 7 are fixedly connected to the circumferential surface of the receiving body 4, the circumferential inner wall of the receiving body 4 is fixedly connected to a silicon carbide brick 10, the lower inner wall of the receiving body 4 is fixedly connected to a graphite electrode brick 11, and the receiving body 4 is coated with a mixture of brown corundum powder and phosphoric acid. This design solves the problem that after the corundum in the original device is collected, the corundum temperature loses quickly due to the inability to effectively keep warm due to the placement of objects, resulting in broken jade.

[0022] As a first embodiment of the present invention, the four ends of the supporting steel frame 6 are fixedly connected to limit blocks 9. The connection cover 5 and the casting body 2 are filled with a mixture of brown corundum aggregate and high-lead cement. The limit blocks 9 installed at the four ends of the supporting steel frame 6 can be connected to a lifting device to facilitate the placement and removal of the connection cover 5 on the surface of the connection body 4. The brown corundum aggregate and high-lead cement mixture inside the connection cover 5 and the casting body 2 effectively insulates the corundum inside the connection body 4, reducing the rate of cooling of the corundum, which would otherwise cause rapid cooling and breakage. The circumferential surface of the connection body 4 is provided with thermal insulation material, and the upper end of the connection body 4 is flat. The thermal insulation material on the surface of the connection body 4 can concentrate the temperature of the corundum inside the connection body 4, reducing the rate of heat loss of the corundum. The connection cover 5 and the connection body 4 are connected to each other, which can enhance the sealing between the connection body 4 and the connection cover 5, and reduce the rate of heat loss of the corundum inside the connection body 4. The limiting tube 1 cooperates with the connecting body 4 to increase the convenience of installing the connecting body 4 in the limiting tube 1. The lower end of the circumference of the connecting body 4 is fixedly connected with four support seats 8, which can be connected with the limiting tube 1 to increase the stability of the connecting body 4 in the limiting tube 1.

[0023] As a second embodiment of the present invention: the corundum is placed into the turned-over connecting body 4 by an excavator, and then the equipment is hoisted to connect the supporting steel frame 6 to cover the connecting cover 5 on the surface of the connecting body 4. The residual heat in the connecting body 4 is used to slowly cool the corundum, avoiding dark cracks in the corundum caused by extreme cold, and better preserving the integrity of the corundum.

[0024] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims are included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.
