Description

Technical Field

[0001] This utility model belongs to the field of white fused alumina production technology, specifically relating to a splash protection device in the white fused alumina production process. Background Technology

[0002] White fused alumina is a synthetic corundum material made from high-purity alumina through melting and crystallization in a high-temperature electric arc furnace. It is characterized by high hardness, high-temperature resistance, and good chemical stability, and is widely used in abrasives, refractory materials, ceramics, and other fields. The processing of white fused alumina requires high-temperature melting. The cooling process after melting requires controlling the cooling rate, and is generally carried out using natural cooling. This process involves pouring molten material into a cooling mold, but splashing is prone to occur during this process. Current solutions often involve guiding the flow of molten material to make it flow more smoothly and installing protective baffles around the mold. However, these only block horizontal splashes, and the molten material that comes into contact with the protective baffles can easily clump together, requiring manual cleaning after machine shutdown. If the high-temperature clumps on the protective baffles are not cleaned in time, they may solidify and fall into the mold, potentially causing secondary splashing, which is quite dangerous. Utility Model Content

[0003] The purpose of this invention is to provide a splash protection device for the production process of white fused alumina. It is equipped with a splash protection box that can completely surround the ceramic molding mold, and a water curtain is constructed on the inner wall of the splash protection box. This not only blocks the splashed molten material, but also allows the molten material to cool and clump quickly and fall outside the ceramic molding mold. There is no need to stop the machine to clean the inner wall of the splash protection box. It has a good protective effect and avoids the generation of secondary splashing, thus having a higher safety factor.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A splash protection device for white fused alumina production process includes a splash protection box, one end of which is fixed with a ceramic guide channel, which is inclined.

[0006] The bottom of the splash-proof protective box is fixed with a slide rail, the top of the slide rail is slidably mounted with a slider, the top of the slider is fixed with an assembly plate, a ceramic forming mold is placed on the top of the assembly plate, and when the assembly plate moves into the splash-proof protective box, the ceramic forming mold is located below the lower end of the ceramic guide channel.

[0007] The bottom of the splash-proof protective box is equipped with a cooling water tank, and the water in the cooling water tank is used to cool the splashed white corundum molten material.

[0008] Furthermore, a motor is fixed to one end of the slide rail, and a threaded rod is installed at the output end of the motor inside the slide rail, the threaded rod being threadedly connected to the slider.

[0009] Furthermore, a water pump is fixed to the top of the splash-proof protective box, a suction pipe is fixed to the input end of the water pump, the inlet of the suction pipe is installed on one side of the bottom of the cooling water tank, and a spray pipe is fixed to the output end of the water pump. The spray pipe is located at the top inside the splash-proof protective box.

[0010] Furthermore, a filter plate is slidably installed inside the cooling water tank, and an electric synchronous lifting rod is fixed at each of the four corners inside the cooling water tank. The output end of the electric synchronous lifting rod is fixed to the bottom of the filter plate.

[0011] Furthermore, the two ends of the top of the splash-proof protective box are rounded, and the water outlet of the water spray pipe is aligned with the curvature of the top inside the splash-proof protective box.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This invention employs a dual protection mechanism: a splash-proof protective box directly blocks splashes, while a water curtain is constructed on the inner wall of the splash-proof protective box to cool the splashed molten material. This effectively blocks the splashed molten material, and the water curtain can quickly cool and agglomerate the splashed molten material, preventing the molten material from adhering to the inside of the splash-proof protective box and forming irregular shapes that could lead to secondary splashing. This significantly increases the safety factor for operators.

[0014] This invention utilizes a coordinated design of a liftable filter plate and circulating water. After cooling and agglomerating, the fused alumina will fall onto the filter plate with the water curtain. During the pouring process, the filter plate is below the water surface of the cooling water tank. The water inside the cooling water tank can cool the fused alumina and collect it. The lifting and lowering of the filter plate completes solid-liquid separation, making it easier to recycle the fused alumina. Attached Figure Description

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1 to 3 As shown, a splash protection device for white fused alumina production process includes a splash protection box 1, one end of which is fixed with a ceramic guide channel 11, which is inclined.

[0022] The bottom of the splash protection box 1 is fixed with a slide rail 12, the top of the slide rail 12 is slidably mounted with a slider 13, the top of the slider 13 is fixed with an assembly plate 14, a ceramic molding mold 15 is placed on the top of the assembly plate 14, and when the assembly plate 14 moves into the interior of the splash protection box 1, the ceramic molding mold 15 is located below the lower end of the ceramic guide channel 11.

[0023] The bottom of the splash-proof protective box 1 is equipped with a cooling water tank 2, and the water in the cooling water tank 2 is used to cool the splashed white corundum molten material;

[0024] In the above process, when pouring the molten white fused alumina, the ceramic forming mold 15 is placed above the assembly plate 14. Then, the ceramic forming mold 15 is slidably sent into the interior of the splash-proof protection box 1. The molten white fused alumina is poured from one end of the ceramic guide channel 11. The molten material flows along the ceramic guide channel 11 and into the interior of the ceramic forming mold 15. The ceramic forming mold 15 is located inside the splash-proof protection box 1. The splashes that occur during the pouring process will be blocked by the splash-proof protection box 1 to ensure the safety of the operator. At the same time, the splashed molten material will eventually drip into the cooling water tank 2. The water inside the cooling water tank 2 can instantly cool the molten material, making it solid, which facilitates the recycling of the splashed white fused alumina material after pouring.

[0025] Please refer to the following: Figure 2 and Figure 3 As shown, a motor 17 is fixed to one end of the slide rail 12, and a threaded rod 16 is installed at the output end of the motor 17 and inside the slide rail 12. The threaded rod 16 is threadedly connected to the slider 13.

[0026] As described above, the motor 17 can control the rotation of the threaded rod 16. When the threaded rod 16 rotates, it can drive the slider 13 to slide along the slide rail 12 under the push of the thread, thereby driving the ceramic forming mold 15 placed above to slide, and driving the ceramic forming mold 15 to enter and exit the splash-proof protection box 1.

[0027] It should be noted that the top of the slide rail 12 is designed to be arc-shaped, so that the splashed molten material dripping onto the slide rail 12 can slide down along the slide rail 12 to the cooling water tank 2. At the same time, when the slider 13 slides, it can scrape the remaining molten material down to the cooling water tank 2.

[0028] Please refer to it again. Figure 3 As shown, a water pump 21 is fixed to the top of the splash protection box 1. A water suction pipe 22 is fixed to the input end of the water pump 21. The water inlet of the water suction pipe 22 is installed on one side of the bottom of the cooling water tank 2. A water spray pipe 23 is fixed to the output end of the water pump 21. The water spray pipe 23 is located at the top inside the splash protection box 1. The two ends of the top of the splash protection box 1 are rounded, and the water outlet of the water spray pipe 23 is aligned with the arc of the top inside the splash protection box 1.

[0029] During the pouring process, the water pump 21 is started to draw water from the cooling water tank 2 through the suction pipe 22 and deliver it to the outlets of the spray pipe 23. Since the top two ends of the splash protection box 1 are set in an arc shape, the water flowing out of the spray pipe 23 will flow along the two sides inside the splash protection box 1, forming a water curtain on both sides of the inner wall of the splash protection box 1. If the molten material splashes onto the inner wall of the splash protection box 1 during the pouring process, it will come into contact with the water curtain and cool down instantly, and then clump and fall off, preventing the splashed molten material from sticking to the inner wall of the splash protection box 1.

[0030] Furthermore, a filter plate 24 is slidably installed inside the cooling water tank 2, and an electric synchronous lifting rod is fixed at the four corners inside the cooling water tank 2. The output end of the electric synchronous lifting rod is fixed to the bottom of the filter plate 24.

[0031] The filter plate 24 described above can filter the agglomerated white fused alumina, allowing the white fused alumina to flow onto the filter plate 24, preventing white fused alumina fragments from clogging the inlet end of the suction pipe 22 and affecting the normal flow of the water curtain. At the same time, the electric synchronous lifting rod can also drive the filter plate 24 to rise and fall. When tilting, the filter plate 24 is controlled to be below the water surface of the cooling water tank 2, which facilitates the contact of splashed molten material with the water to cool and agglomerate. After tilting is completed, the height of the filter plate 24 can be adjusted so that the filter plate 24 is above the water surface, which facilitates the recovery of the white fused alumina collected on the filter plate 24.

[0032] The working principle of this utility model is as follows: A ceramic molding mold 15 is placed above an assembly plate 14. The motor 17 is started, driving the threaded rod 16 to rotate, causing the slider 13 and the ceramic molding mold 15 placed on it to move together into the splash-proof protection box 1. The movement stops below one end of the ceramic guide channel 11. The water pump 21 is then started, causing water from the cooling water tank 2 to flow through the suction pipe 22 to the outlet of the spray pipe 23, allowing the water to flow along both sides of the inner wall of the splash-proof protection box 1, forming a continuously flowing water curtain. Then, the molten material is poured into the ceramic... At one end of the guide channel 11, the molten material flows into the ceramic forming mold 15 through the ceramic guide channel 11. If splashing occurs during the process and drips into the water stored in the cooling water tank 2, it will be cooled quickly and remain on the filter plate 24. If splashing onto the inner wall of the splash protection box 1, it will come into contact with the water curtain and be cooled quickly, and then flow into the cooling water tank 2 along the water curtain. After being blocked by the filter plate 24, it will flow onto the filter plate 24. After the pouring operation is completed, by lifting the filter plate 24, the white corundum agglomerates remaining on the filter plate 24 can be moved upward, making it convenient to recycle the white corundum agglomerates.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
