[0002] A protective casing is an outer tube shell used to protect a pipeline. It is usually made of wear-resistant, corrosion-resistant or insulating materials to provide additional protection and safety. During the steelmaking process, molten steel needs to undergo various treatments, which may produce impurities such as slag. These impurities affect the quality and purity of the molten steel and may even cause production accidents. Therefore, in order to protect the molten steel from these external factors, specially designed casings are required for protection.

When the pipeline is accidentally hit, the pipeline has the risk of shaking and falling off, and steel slag is easily accumulated at the bottom of the inner wall of the pipeline. Through a single flushing, some steel slag still remains in local areas, resulting in incomplete cleaning and affecting the next normal use. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 3 The utility model provides the following technical solutions: a high-temperature wear-resistant insulating protective sleeve for preventing slag and molten steel, comprising: a sleeve body 1, a protective layer 2 is provided on the outermost side of the sleeve body 1, an insulating layer 4 is provided on the inner side of the protective layer 2, a wear-resistant layer 6 is provided on the inner side of the insulating layer 4, a high-temperature resistant layer 8 is provided on the inner side of the wear-resistant layer 6, a bearing plate 10 is provided below the sleeve body 1, mounting plates 11 are fixed on both sides of the upper end surface of the bearing plate 10, thread grooves 12 are provided on the two mounting plates 11, and clamping plate assemblies are provided in the two thread grooves 12.

[0021] Furthermore, the clamping plate assembly includes a threaded rod 13, a clamping plate 14 and a mounting block 16. The threaded rod 13 is screwed through the threaded groove 12. The clamping plate 14 is installed at one end of the threaded rod 13 close to the sleeve body 1. A bearing 15 is provided between the threaded rod 13 and the clamping plate 14. The mounting block 16 is fixed at one end of the threaded rod 13 away from the clamping plate 14. The bearing 15 makes it difficult for the clamping plate 14 to rotate with the rotation of the threaded rod 13.

[0022] Furthermore, an anti-slip groove 3 is provided on the protective layer 2 , and the insulating layer 4 is filled with insulating material 5 .

[0023] Furthermore, the wear-resistant layer 6 is provided with a wear-resistant material 7 , and the high-temperature-resistant layer 8 is provided with a high-temperature-resistant material 9 .

[0024] Through the above technical solution:

[0025] When in use, the high temperature resistant material 9 is a high temperature ceramic, a silicate material or a high temperature resistant metal alloy, etc., which can withstand the high temperature environment of molten steel without being damaged. The wear-resistant material 7 can be selected from silicon carbide, boron carbide, aluminum oxide, etc., which must have good wear resistance and be able to resist the erosion of steel slag. The insulating material 5 has good insulating properties to avoid heat conduction to the outside and reduce the influence of the external environment on the temperature of the molten steel. The protective layer 2 is composed of a material with a relatively large hardness, so that the sleeve body 1 as a whole is not easy to deform. After the sleeve body 1 is installed, the threaded rod 13 is screwed, and the clamping plate 14 is moved through the interaction between the threaded rod 13 and the thread groove 12. The clamping plate 14 is an arc-shaped plate that can fit the outer wall of the sleeve body 1. Multiple clamping plates 14 interact with each other to clamp the sleeve body 1, increase the stability of the sleeve body 1 during work, reduce work interruptions or errors caused by shaking or moving the sleeve body 1, improve safety, and effectively prevent the sleeve body 1 from accidentally sliding or falling off during work, thereby improving the safety of the work site.

[0026] See also Figure 1 and Figure 4 As shown, a support plate 17 is installed above the bearing plate 10, and a mounting groove 18 is opened on the support plate 17. A plurality of rolling components are arranged in the mounting groove 18, and the sleeve body 1 is located on the rolling components.

[0027] Furthermore, the rolling assembly includes a motor 19 , a rotating shaft 20 and a roller 21 . The motor 19 is mounted on the side wall of the support plate 17 , the rotating shaft 20 is connected to the output end of the motor 19 , the roller 21 is mounted on the outer wall of the rotating shaft 20 , and the roller 21 is located in the mounting groove 18 .

[0028] Through the above technical solution:

[0029] When cleaning, the threaded rod 13 is screwed to move the clamping plate 14 away from the sleeve body 1 to release the sleeve body 1, and then the motor 19 is started. The motor 19 drives the roller 21 to rotate through the rotating shaft 20. The rotation of multiple rollers 21 in the same direction can drive the sleeve body 1 to rotate. The rotating sleeve body 1 makes the internal water flow cover more comprehensively, so as to more effectively clean the internal steel slag and prevent the slag residue from remaining in the local area, so as to achieve a more thorough cleaning effect, and effectively reduce the corrosion and wear of the pipeline, extend the service life of the pipeline and related equipment, and improve the reliability and stability of the sleeve body 1.
