Technical Field
[0001] This utility model relates to the field of slag retaining walls, specifically a slag retaining wall with a flow guiding structure. Background Technology
[0002] Slag retaining walls are key equipment used in metallurgical, casting and other industrial fields to block molten slag and separate impurities, playing an irreplaceable role in ensuring product quality and improving production efficiency.
[0003] Publication No. CN222429260U discloses a tundish slag retaining wall with high erosion resistance, comprising a first slag retaining wall body, a second slag retaining wall body, a steel flow port, and reinforcing sleeves. The second slag retaining wall body is fixedly connected to the left and right sides of the first slag retaining wall body. Steel flow ports are provided on both the first and second slag retaining wall bodies. Reinforcing sleeves are fixedly installed on the first and second mounting plates. In many industrial fields such as steel smelting and casting, slag retaining walls are important equipment for ensuring product quality, especially in the flow guidance of high-temperature fluids such as molten steel and iron. Preventing impurities from flowing out is crucial, as it can severely impact the quality of subsequent products. For example, it can lead to defects such as porosity and inclusions within the steel, reducing the product's mechanical properties and lifespan. Therefore, installing filters inside the guide pipes of the slag retaining wall has become a common practice in the industry. These fine filters intercept various impurities, effectively improving the purity of the fluid and ensuring the production of high-quality products. However, the existing filter fixing structure uses threaded connections, a method that has revealed numerous problems in long-term practice. Firstly, the installation process is extremely cumbersome. Due to the complex working environment, limited space, and inconvenient operation, workers must carefully thread the filter screen and guide pipe together, precisely aligning the threads before tightening. This process consumes a significant amount of manpower and time, severely impacting production efficiency. Furthermore, even slight deviations during installation can lead to loose thread engagement, affecting the fixing effect. On the other hand, when impurities filtered by the filter screen cool and solidify, they can clog the pores, reducing or even completely blocking the flow. In such cases, the filter screen must be disassembled and replaced. However, due to the extremely high temperature and fluidity of molten steel and other high-temperature fluids, molten steel is easily disturbed during flow due to various factors such as equipment vibration, fluid impact, and improper operation. Once it flows onto the threaded teeth, it solidifies instantly, firmly jamming the threads. This makes subsequent disassembly difficult with conventional tools, and even special methods may damage the guide pipe and filter screen, increasing maintenance costs. Forced disassembly may also damage the threaded structure of the guide pipe, making normal filter screen installation impossible, further affecting production continuity and causing significant economic losses to the company. Utility Model Content
[0004] The purpose of this invention is to provide a slag-blocking wall with a flow-guiding structure. By using this device, the problem that forced disassembly may damage the threaded structure of the flow-guiding pipe, making it impossible to install the filter screen normally, further affecting the continuity of production, and causing huge economic losses to enterprises can be solved.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a slag-blocking wall with a flow guiding structure, comprising a slag-blocking wall body, a flow guiding pipe disposed inside the slag-blocking wall body, a fixing plate disposed on one side of the slag-blocking wall body, a filter screen fixedly connected to the inner side of the fixing plate, a snap-fit mechanism disposed on the other side of the slag-blocking wall body, and a threaded mechanism disposed above the snap-fit mechanism.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 The present invention provides a technical solution: a slag retaining wall with a flow guiding structure, including a slag retaining wall body 1, a flow guiding pipe 2 disposed inside the slag retaining wall body 1, a fixing plate 3 disposed on one side of the slag retaining wall body 1, a filter screen 4 fixedly connected to the inner side of the fixing plate 3, a buckling mechanism 5 disposed on the other side of the slag retaining wall body 1, and a threaded mechanism 6 disposed above the buckling mechanism 5.
[0023] The main body 1 of the slag retaining wall has a hole 7 inside. The latching mechanism 5 includes a connecting rod 501 fixedly connected to the fixing plate 3 inside the hole 7. The inner side of the hole 7 fits against the outer side of the connecting rod 501, and the central axis of the connecting rod 501 is perpendicular to the central axis of the main body 1 of the slag retaining wall, so that the connecting rod 501 will not shake when it moves inside the hole 7. The connecting rod 501 has a first groove 502 inside, and a locking block 503 is provided inside the first groove 502. The end of the locking block 503 away from the central axis of the main body 1 of the slag retaining wall is fixedly connected to the connecting plate 504. The width of the first groove 502 is greater than the width of the locking block 503, reducing the contact surface between the locking block 503 and the hole 7. The lower end surface of the locking block 503 is an inclined surface, and the upper end of the inclined surface of the locking block 503 is closer to the main body 1 of the slag retaining wall than the lower end of the inclined surface of the locking block 503, so that the locking block 503 pushes the connecting rod 501 along its inclined surface.
[0024] The threaded mechanism 6 includes a support plate 601 fixedly connected to the side of the slag retaining wall body 1 near the connecting plate 504. A threaded rod 602 is threadedly connected inside the support plate 601. A second groove 603 is provided inside the upper end of the connecting plate 504. A rotating disk 604 fixedly connected to the threaded rod 602 is provided inside the second groove 603. A first fixed cylinder 605 is fixedly connected to the upper end of the connecting plate 504. A second fixed cylinder 606 fixedly connected to the support plate 601 is provided inside the first fixed cylinder 605. A third fixed cylinder 607 is fixedly connected to the upper end of the support plate 601. A fourth fixed cylinder 608 fixedly connected to the threaded rod 602 is provided inside the third fixed cylinder 607. The rotating disk... The external structure of 604 is cylindrical, and the lower end of the rotating disk 604 is wider than the upper end, so that the rotating disk 604 will not wobble when moving inside the second groove 603, and will not move out of the interior of the second groove 603. The inner side of the first fixed cylinder 605 is in contact with the outer side of the second fixed cylinder 606, and the external structure of the second fixed cylinder 606 is cuboid, so that the first fixed cylinder 605 can move up and down without rotating. The inner side of the third fixed cylinder 607 is in contact with the outer side of the fourth fixed cylinder 608, and the external shape of the fourth fixed cylinder 608 is cylindrical, so that the fourth fixed cylinder 608 can move up and down and can rotate.
[0025] When installation is required, align the connecting rod 501 with the hole 7, rotate the threaded rod 602. Since the threaded rod 602 is connected to the support plate 601 by a threaded connection, and the rotating disk 604 has a cylindrical shape with a lower width greater than its upper width, the inner side of the first fixing cylinder 605 fits against the outer side of the second fixing cylinder 606, and the second fixing cylinder 606 has a cuboid shape. This causes the rotating disk 604 to drive the connecting plate 504 and the locking block 503 to move vertically downwards, causing the locking block 503 to move downwards into the interior of the first groove 502. The lower end face of 03 is an inclined surface, and the upper end of the inclined surface of the card block 503 is closer to the slag retaining wall body 1 than the lower end of the inclined surface of the card block 503, so that the inclined surface of the card block 503 contacts the first groove 502, pushing the connecting rod 501, the fixing plate 3 and the filter screen 4 to move to one side of the connecting plate 504, and fixing the connecting rod 501, fixing the connecting rod 501, the fixing plate 3 and the filter screen 4. Since the card block 503 and the first groove 502 have only one contact surface, and the outer side of the card block 503 is a horizontal surface, even if molten steel comes into contact with the outer side of the card block 503, it is easy to clean, making the installation process convenient.
[0026] The first fixed cylinder 605 and the second fixed cylinder 606 cooperate to protect the lower end of the threaded rod 602, while the third fixed cylinder 607 and the fourth fixed cylinder 608 protect the upper end of the threaded rod 602, reducing the damage of molten steel to the thread teeth of the threaded rod 602.
