[0002] In the power, metallurgy, chemical industry and other industries, the cooling treatment of high-temperature materials is an important link in the production process. Especially in the process of slag removal in power plants, using cooling cylinder to cool high-temperature slag is a key operation. The cooling cylinder is designed by the internal structure to ensure that the material can be uniformly cooled and smoothly delivered to the subsequent processing system. Such equipment not only needs to have high heat exchange performance, but also needs to ensure the safety and stability of operation to adapt to the needs of different working conditions.
[0003] Although the existing cooling cylinder has made significant progress in improving heat exchange efficiency, it still has deficiencies in preventing high-temperature slag from splashing. For example, in some cooling cylinders, due to the lack of effective internal blocking measures, when high-temperature slag enters the cooling section, it may produce irregular motion due to fluid change, which may cause hot slag to directly splash into the internal of the next slag conveying system, which not only may cause damage to the conveying equipment, but also may affect the safe operation of the whole system. To solve this problem, the existing technology often focuses on external protection or post-processing, and cannot fundamentally solve the splashing phenomenon of slag during cooling. Therefore, a more effective anti-spraying slag structure is needed to optimize this problem. SUMMARY

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an anti-spraying slag device for cooling cylinder, comprising a cylinder body, a plurality of groups of flow resistance plates are uniformly arranged inside the cylinder body, the flow resistance plate is a "V" shaped structure composed of an inner guide plate and an outer guide plate, the inner guide plate and the outer guide plate are arranged along the length direction of the cylinder body to form a tapered channel, which gradually narrows from one end to the other end, and the two sides of the rear end of the inner guide plate and the outer guide plate are connected by a connecting piece, and the front end of the outer guide plate is provided with a plurality of flow splitting cones, and the gap between the flow splitting cones is connected with guide vanes.
[0006] Preferably, a plurality of butt blocks are arranged on the inner wall of the cylinder body, and the front end of the inner guide plate is provided with a U-shaped butt seat consistent with the structure of the butt block, and high-temperature resistant fixing bolts are connected to the U-shaped butt seat by thread structure.
[0007] Preferably, the inner wall of the inner and outer flow guide plates are provided with a plurality of rectangular grooves, and the rectangular grooves are arranged at equal intervals along the length direction of the flow resistance plate.
[0008] Preferably, the outer shape of the flow distribution cone is a progressive arc structure, and the outer wall of the flow distribution cone is provided with a plurality of reinforcing ribs.
[0009] Preferably, the cross section of the guide vane is a trapezoidal structure, and the edge of the guide vane is an arc transition surface structure.
[0010] Preferably, the outer wall of the outer flow guide plate is provided with a plurality of guide grooves, and the guide grooves are in a wave shape structure as a whole.
[0011] Compared with the prior art, the cooling cylinder anti-spraying slag device effectively guides and slows down the flow of slag through the internal multiple flow resistance plates, prevents hot slag from being directly sprayed into the next level of slag conveying system, thereby improving the safety and stability of the equipment operation, and ensuring the smooth progress of the entire cooling process. The device, through the inner and outer flow guide plates designed in a "V" shape structure, cooperates with the design of the tapered channel, not only optimizes the flow path of the slag, but also significantly reduces the kinetic energy and reduces the impact on the subsequent system. The flow distribution cone and the guide vane further refine the flow control of the slag, and realize more uniform and stable cooling effect. BRIEF DESCRIPTION OF DRAWINGS

When the high-temperature slag impacts the flow divider 4, this design can effectively guide the flow direction of the slag, so that it is smoothly divided into multiple small streams, reduces the direct impact force and avoids irregular motion, and at the same time, the plurality of reinforcing ribs arranged on the outer wall of the flow divider 4 enhance the structural strength, so that the flow divider 4 will not be deformed or damaged in a high-temperature and high-pressure environment. The cross section of the guide vane 5 is in a trapezoidal structure, and the edge of the guide vane 5 is an arc transition surface structure. The trapezoidal structure of the guide vane 5 helps to stabilize the slag flow and reduce its kinetic energy, preventing splashing caused by irregular motion. The arc transition surface structure of the edge of the guide vane 5 further optimizes the flow trajectory of the slag, so that the slag can smoothly turn when passing through the guide vane 5, reducing local resistance and turbulent flow phenomena, thereby reducing energy loss. The outer wall of the outer guide plate 22 is provided with a plurality of guide grooves 10, and the guide grooves 10 are in a wave shape structure as a whole. This structure can effectively guide and adjust the flow path of the slag, that is, the slag is constantly guided by the guide grooves 10 during flow, producing regular small turbulent flow, increasing the heat exchange efficiency between the slag and the outer guide plate 22, and at the same time reducing the wear caused by the direct impact of the slag on the surface of the guide plate.
[0018] Working principle: When using the cooling cylinder anti-spraying slag device, first, the high-temperature slag enters the inside of the cylinder 1, directly contacts a plurality of flow dividers 4 arranged at the front end of the outer guide plate 22, and the flow divider 4 divides the high-speed flowing slag into multiple small streams. Subsequently, the slag moves along the tapered channel formed by the "V" shaped structure of the inner guide plate 21 and the outer guide plate 22. During this process, the channel gradually narrows from one end to the other, forcing the slag to slow down and distribute evenly. At the same time, the guide vane 5 further guides the flow direction of the slag, making it move smoothly along the predetermined path and reducing the direct impact on the subsequent system. As the slag continues to move along the tapered channel, it will pass through the rectangular grooves 9 on the inner wall of the inner guide plate 21 and the outer guide plate 22. These grooves cause the slag to produce small turbulent flow, increasing the contact time and area between the slag and the guide plate. If the slag flows along the outer wall of the outer guide plate 22, the wave-shaped guide grooves 10 adjust the flow path of the slag, ensuring that the slag is constantly subjected to regular guidance during flow. At the same time, the inner guide plate 21 can be clamped to the abutting block 6 through the U-shaped abutting seat 7, and can be stably connected or disassembled through the high-temperature resistant fixing bolt 8 passing through the reserved hole, ensuring the stable installation of the guide plate in a high-temperature environment and preventing displacement or loosening, thereby completing a series of work.
