Description

Technical Field

[0001] This utility model relates to the technical field of slurry conveying equipment, and in particular to a wear-resistant pipe tee for slurry. Background Technology

[0002] In the transportation of highly abrasive media such as slurries and granular materials, pipe tees, as common connecting components, face severe wear problems. Traditional tee pipes, when transporting such media, are extremely prone to severe wear at the connection between the main pipe and branch pipes due to the high flow velocity and high particle hardness of the media itself. Frequent replacement of tee pipes significantly increases operating costs for enterprises and causes numerous inconveniences to production.

[0003] Existing wear-resistant measures also have many shortcomings. For example, while conventional wear-resistant coatings (such as ceramic plates) have a certain degree of wear resistance, they are prone to peeling off during actual use, significantly reducing their wear-resistant effect. Furthermore, the encapsulation structure is not only complex to design but also difficult to maintain. Additionally, while thickening the entire pipeline can improve wear resistance to some extent, it significantly increases costs, making it economically impractical. Therefore, there is an urgent need for a new, efficient, and economical wear-resistant tee structure for slurry pipelines to address these issues. Utility Model Content

[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] The purpose of this utility model is to provide a wear-resistant pipe tee for slurry, which solves the problems existing in the prior art. It has a simple structure, effectively improves wear resistance, and effectively saves costs.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a wear-resistant pipe tee for slurry, such as... Figure 1 As shown, the tee includes: a pipe tee body 1, a wear-resistant layer 2, a wear-resistant short section 3, and a wear-resistant component 4. The pipe tee body 1 includes an integrally connected main pipe and branch pipe; the wear-resistant layer 2 is disposed on the inner wall of the pipe tee body 1; the wear-resistant short section 3 is disposed on the outer side of the main pipe extending in the opposite direction of the branch pipe; and the wear-resistant component 4 is disposed on the outer side of the ore-facing bend at the connection between the branch pipe and the main pipe. Through this overall structural arrangement, the components cooperate with each other. The wear-resistant layer 2 provides wear protection from the inside of the pipe, the wear-resistant short section 3 from the part of the branch pipe impacting the main pipe, and the wear-resistant component 4 from the outer side of key connection parts such as the ore-facing bend at the connection between the branch pipe and the main pipe, effectively addressing the high wear problem during slurry transportation. This provides a basic framework for the subsequent specific wear-resistant design of each part, improving the wear resistance and service life of the entire pipe tee.

[0025] In a preferred embodiment, the body 1 of the pipeline tee is made of Q235 steel with a thickness of 8-10mm. Q235 steel has good comprehensive mechanical properties, providing a solid structural support for the pipeline tee. The appropriate thickness ensures that it does not deform or break when subjected to the pressure and impact of slurry, ensuring the basic structural strength and transportation safety of the pipeline, and meeting the long-term and stable slurry transportation needs.

[0026] In a preferred embodiment, the wear-resistant layer 2 is formed by spraying wear-resistant material onto the inner wall of the pipe tee body 1. The wear-resistant layer 2 is formed by spraying multi-metal wear-resistant material onto the inner wall of the pipe, which can directly resist the scouring and wear of particles in the slurry on the inner wall of the pipe, prevent the inner wall of the pipe from being worn thin by rapid wear, thereby extending the overall service life of the pipe tee and reducing the frequency of replacement due to wear of the inner wall.

[0027] In a preferred embodiment, the wear-resistant layer 2 has a thickness of 8–10 mm. This thickness ensures sufficient resistance to slurry particles without excessively increasing costs or affecting other pipeline performance due to excessive thickness. A suitable thickness provides durable and effective wear protection, stably maintaining the pipeline's wear resistance.

[0028] In a preferred embodiment, the wear-resistant short section 3 has a U-shaped structure. The U-shaped structure can better adapt to the special structure of the connection between the branch pipe and the main pipe and the flow path of the slurry. It plays a buffering and guiding role in the flow of the slurry, reduces the direct impact of the slurry on the connection, and thus effectively reduces the wear degree of this part and improves the wear resistance of the tee in this critical part.

[0029] In a preferred embodiment, the bending angle of the wear-resistant short section 3 is 120-180°. This bending angle range helps to more accurately adapt to the flow of slurry under different working conditions, further optimize the flow trajectory of slurry, more effectively disperse the impact force of slurry at the joint, ensure the formation of a stable and effective wear-resistant protection zone in key parts, and minimize wear.

[0030] In a preferred embodiment, the length of the wear-resistant short section 3 is 2 to 3 times the diameter of the branch pipe. The appropriate length can provide sufficient and comprehensive wear-resistant protection for the weak connection, ensure effective coverage of the slurry impact area, and ensure that the critical part can be fully protected under long-term and high-wear conditions, thus guaranteeing the wear resistance and reliability of the tee.

[0031] In a preferred embodiment, the wear-resistant short section 3 is welded and fixedly connected to the pipe tee body 1. The outer periphery of the wear-resistant short section 3 is provided with a welding bevel with an angle of 30-45°. The welded and fixed connection ensures the firmness of the connection between the wear-resistant short section 3 and the pipe tee body 1, so that it will not loosen or fall off under long-term impact and vibration of slurry. The welding bevel with a specific angle helps to improve the welding quality, enhance the weld strength, and make the entire wear-resistant structure more stable and reliable, ensuring that the wear-resistant short section 3 and the pipe tee body 1 work together to play a wear-resistant role.

[0032] In a preferred embodiment, the wear-resistant short section 3 is made from processed waste wear-resistant pipes. Using waste wear-resistant pipes to process and manufacture the wear-resistant short section 3 effectively utilizes waste resources, reduces the consumption of new materials and the generation of waste, and greatly reduces production costs. Without reducing the wear resistance of the tee, it improves the economic benefits and environmental friendliness of the product.

[0033] In a preferred embodiment, the wear-resistant component 4 is a semi-circular ring structure on the outside of the ore-facing bend at the connection between the branch pipe and the main pipe, which is sprayed with wear-resistant material. The wear-resistant component 4 with the semi-circular ring structure is set for the area where the impact and wear of the ore slurry are most severe. It can specifically improve the wear resistance of this part, directly bear and disperse the impact force of the ore slurry on this area, effectively reduce local wear, protect the pipeline structure in all directions, and ultimately significantly extend the service life of the tee as a whole.

[0034] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
