Description

Technical Field

[0001] This utility model relates to the technical field of brick forming equipment, and in particular to a sintering equipment for producing corundum bricks with ultra-high thermal shock life. Background Technology

[0002] Corundum bricks are high-grade refractory materials made primarily from high-purity alumina. Due to their excellent high-temperature resistance, wear resistance, and corrosion resistance, they are widely used in high-temperature industries such as metallurgy, glass, and ceramics. The production process includes raw material selection and pretreatment (selecting fused alumina, sintered alumina, etc., and classifying them by particle size), batching and mixing (precisely proportioning the main materials and additives, and mixing them uniformly), forming (forming green bodies using dry pressing and static pressing methods), drying (removing moisture from the green bodies), and sintering (high-temperature firing in equipment such as shuttle kilns and tunnel kilns). Sintering equipment is a crucial step in corundum brick production. Its heating method, temperature control accuracy, and atmospheric environment directly affect the crystal structure, density, and properties of the corundum bricks. For example, during high-temperature sintering, the uniform heating capacity of the kiln determines the thermal shock stability of the corundum bricks. Advanced sintering equipment, by optimizing temperature curves and heat flow distribution, can significantly improve the quality and production efficiency of corundum bricks. Therefore, the technical level of the sintering equipment is one of the core factors determining the quality of corundum brick products. Chinese patent CN217257143U discloses a brick-making device for manufacturing high thermal shock chromium corundum bricks, relating to the technical field of brick forming equipment. Specifically, it is a brick-making device for manufacturing high thermal shock chromium corundum bricks, including a worktable. A forming hydraulic cylinder is mounted above the worktable, and a transmission plate is fixedly connected to the output shaft of the forming hydraulic cylinder. A forming block is fixedly installed at the bottom of the transmission plate, and an adjusting hydraulic rod is fixedly installed at the top of the worktable. This brick-making device for manufacturing high thermal shock chromium corundum bricks moves the feeding head to the top of the forming cavity by adjusting the hydraulic rod. A first drive motor drives the auger blades to rotate, feeding the material into the forming cavity, achieving automatic feeding. Furthermore, when the feeding head resets, it can scrape the material inside the forming cavity, improving both the feeding speed and efficiency. This solves the problems of slow manual feeding and safety hazards associated with previous methods. However, this technical solution only focuses on the forming process of corundum bricks, neglecting the treatment and utilization of the heat energy generated during firing, thus wasting energy and reducing the practicality of the equipment. Specifically, corundum brick firing requires a high-temperature environment above 1600℃. After completing the sintering process, traditional kilns directly emit large amounts of high-temperature flue gas (temperatures can reach above 1200℃), and the heat energy contained in it is not effectively utilized, resulting not only in energy waste but also increasing the production costs of enterprises. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a brick-making device for manufacturing high thermal shock chromium corundum bricks. By adding a gas guiding mechanism and a gas ejection mechanism, the invention aims to change the dead zones that occur in traditional mechanisms during the firing process and improve the utilization of high-temperature gases generated during firing, thereby enhancing the practicality of the device and the quality of the final product.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a sintering equipment for producing corundum bricks with ultra-high thermal shock life, comprising a box body, an anti-dead angle mechanism fixedly connected inside the box body, an energy utilization mechanism fixedly connected inside the box body, two box doors rotatably connected to the front side of the box body, and an inner liner fixedly connected inside the box body.

A support sliding plate is slidably connected inside the support plate. Multiple air outlets are opened inside the support sliding plate. Multiple jets are fixedly connected inside the support sliding plate. Multiple support sliding plates correspond to the air outlets. A brick blank is slidably connected to the top of the support sliding plate. As a further description of the above technical solution: the energy utilization mechanism includes a gas collecting block, the top of which is fixedly connected to the bottom of the inner liner. The interior of the box has a cavity, and the bottom of the cavity and the bottom of the inner liner are both provided with connected through holes. The gas collecting block corresponds to the through holes. An air inlet is fixedly connected to the interior of the cavity. A main air guide pipe is fixedly connected to the interior of the air inlet. The exterior of the main air guide pipe is fixedly connected to the interior of the box. Multiple branch pipes are fixedly connected to the right side of the main air guide pipe. As a further description of the above technical solution: four support legs are fixedly connected to the bottom of the box body, and anti-slip pads are fixedly connected to the bottom of the four support legs. Two support diagonal rods are fixedly connected to the adjacent side of two support legs. As a further description of the above technical solution: the support plate has a sliding groove inside, the two sides of the support sliding plate are slidably connected in the sliding groove, the two sides of the support sliding plate are provided with guide blocks, the two sides of the sliding groove are provided with guide grooves, and the guide blocks are slidably connected in the guide grooves; As a further description of the above technical solution: the support plate has multiple mounting slots inside, and multiple jets are fixedly connected in the mounting slots; As a further description of the above technical solution: the gas collecting block is a square ring shape, and the inner side of the gas collecting block is provided as a slope; As a further description of the above technical solution: a firing groove is provided inside the box body, and the two box doors are rotatably connected in the firing groove; As a further description of the above technical solution: multiple through holes are provided on the left side of both the inner liner and the support plate, and the diversion pipe is fixedly connected inside the through holes.

[0005] This utility model has the following beneficial effects: 1. In this utility model, during the firing of corundum bricks, the high-pressure and high-temperature gas inside the box is guided into the cavity at the top of the box through the gas collecting block due to its own pressure. Then, the high-temperature and high-pressure gas enters the gas guiding pipe through the air inlet to provide power gas for the subsequent anti-dead angle mechanism. Because the gas itself is heated inside the box, the power gas does not need to be heated when the anti-dead angle mechanism is used, thereby improving the energy efficiency of the device.

[0006] 2. In this utility model, high-temperature and high-pressure air guided by the main air pipe flows through multiple diversion pipes located outside the main air pipe to the jet nozzle fixed inside the support plate. With the help of the jet nozzle, the gas is ejected and then released to the bottom of the brick blank through the air outlet located inside the support sliding plate, thereby pushing the brick blank and suspending it, thus avoiding dead corners during the firing process, or even sticking to the top of the support sliding plate.

[0007] In summary, this utility model has the advantages of cleverly utilizing the high-pressure and high-temperature gas during the firing process and guiding it to the anti-dead-angle mechanism as a power source to avoid secondary heating and energy consumption, thus significantly improving energy efficiency; at the same time, by cooperating with the jet nozzle through the diverter pipe, the gas is sprayed out from the air outlet of the supporting sliding plate, lifting the brick blank and suspending it, effectively eliminating firing dead angles, preventing the brick blanks from sticking together, and improving firing quality and efficiency.

The anti-dead angle mechanism is fixedly connected inside the box body 1. The anti-dead angle mechanism is designed to prevent material from stagnating inside the box body 1 during the sintering process, ensuring uniform airflow and effectively removing undesirable gases. The energy utilization mechanism is fixedly connected inside the box body 1. Two doors 2 are rotatably connected to the front of the box body 1. The doors 2 are located on the front of the box body 1, which facilitates the user to load and unload the equipment before and after sintering. The inner liner 12 is fixedly connected inside the box body 1. The inner liner 12 is an important component inside the box body 1. The inner liner 12 surrounds the entire sintering area.

[0013] Example 2 like Figure 1 , Figure 2 , Figure 5As shown, components identical or corresponding to those in Embodiment 1 are referenced using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is that the energy utilization mechanism includes a gas collecting block 13, located at the bottom of the inner liner 12 and connected to the through-hole of the cavity. It is a square ring shape with a sloping inner side to help collect gas flowing out from the through-holes on both sides of the inner liner 12 and the support plate 10. The top of the gas collecting block 13 is fixedly connected to the bottom of the inner liner 12. A cavity is provided inside the housing 1, and the bottom of the cavity and the bottom of the inner liner 12 are both provided with connected through-holes. The gas collecting block 13 corresponds to the through-hole. An air inlet 6 is fixedly connected inside the cavity. The air inlet 6 is installed inside the housing 1 and introduces gas into the gas collecting block 13 through the air guide pipe 7. A... The main air guide pipe 7 is responsible for guiding the airflow to each branch pipe 8 and then distributing it to different areas. The exterior of the main air guide pipe 7 is fixedly connected to the interior of the housing 1. Multiple branch pipes 8 are fixedly connected to the right side of the main air guide pipe 7. These multiple branch pipes 8 are connected to the right side of the main air guide pipe 7 and are responsible for further distributing the gas to other parts that need to be vented. The gas collection block 13 is a square ring shape. The inner side of the gas collection block 13 is provided with a slope. Multiple through holes are opened on the left side of the inner liner 12 and the support plate 10. The branch pipes 8 are fixedly connected to the interior of the through holes. Four support legs 3 are fixedly connected to the bottom of the housing 1. The support legs 3 and the support diagonal rods 4 provide stable support for the equipment. The number of support legs 3 is four to ensure that the equipment can be stably fixed during operation. Anti-slip pads 5 are fixedly connected to the bottom of the four support legs 3. Two support diagonal rods 4 are fixedly connected to the adjacent side of two support legs 3. The function of the support diagonal rods 4 is to further enhance the structural stability of the equipment and prevent the housing 1 from deforming or tilting under high temperature or pressure changes.

[0014] Work steps Rotate the box door 2 to open the feed port inside the box 1, then pull the support sliding plate 11. With the help of the sliding groove inside the support plate 10, slide out of the box 1. Then place the brick blank 14 on top of the support sliding plate 11. At this time, the brick blank 14 covers the air outlet inside the support sliding plate 11 while it is placed on top of the support sliding plate 11. During the firing process, the air inside the box 1 is heated due to the firing process, which increases the air pressure. This causes the gas to enter the cavity inside the box 1 through the gas collecting block 13. The air inlet 6 located in the cavity guides the gas into the main air guide pipe 7. The main air guide pipe 7 and the diversion pipe 8 work together to provide power for the anti-dead angle mechanism. After receiving the power from the diversion pipe 8, the anti-dead-angle mechanism sprays out high-temperature gas through the jet 9. The sprayed gas forms an air wall at the bottom of the brick blank 14 through the air outlet inside the supporting sliding plate 11, so that the brick blank 14 is suspended, thereby avoiding dead angles during the firing process, which would affect the firing yield and the quality of the finished product. The four support legs 3 located at the bottom of the housing 1, with the assistance of the support diagonal rods 4 between the two support legs 3, ensure the stability of the housing 1 during operation. At the same time, the anti-slip pads 5 located at the bottom of the support legs 3 prevent the housing 1 from sliding, thereby ensuring the stability of the device.

[0015] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
