[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below with the drawings and specific embodiments.

[0023] The utility model provides a kind of wear-resistant ore pulp pipeline elbow, as shown in figure Figure 1 First flange 2 is used to be fixedly connected with the first end, and first flange 2 is provided with a plurality of first bolt holes;Second flange 3 is used to be fixedly connected with the second end, and second flange 3 is provided with a plurality of second bolt holes;The first wear layer 4 is fixedly connected to the inner wall of the elbow body 1;And the second wear layer 5 is fixedly connected to the outer side of the first wear layer 4, by setting first flange 2 and second flange 3 and setting bolt hole fixed connection mode, it is convenient to be connected with other pipelines or equipment, the setting of a plurality of bolt holes provides standardized connection mode, so that connection is more stable and reliable, can adapt to different connection needs and use scene, improve the versatility and interchangeability of device, while ensuring the stability of connection under high pressure, high flow rate and other working conditions, avoid leakage at the connection, ensure the normal progress of ore pulp 6 transport, the first wear layer 4 is directly fixed on the inner wall of elbow body 1, so that the first wear layer 4 can be closely attached to the inner wall of elbow, better directly withstand the impact and friction of solid particles in ore pulp 6, enhance the wear resistance of the inner wall of elbow body 1, effectively protect elbow body 1, prolong its service life, reduce pipeline damage and replacement frequency caused by abrasion, reduce maintenance cost, the second wear layer 5 is fixed on the outer side of the first wear layer 4, forms double-layer wear-resistant protective structure. Two wear layers cooperate with each other, further enhance the wear resistance of the whole pipeline elbow, can effectively resist the scouring of solid particles in ore pulp 6 to the inner wall of elbow, reduce the degree of abrasion, significantly improve the service life of pipeline elbow in harsh working environment, ensure the long-term stable operation of ore pulp 6 transport.

[0024] In a preferred embodiment, the first wear-resistant layer 4 is in the form of a circular tube structure, which can better fit the inner wall of the elbow pipe body 1 and form a continuous and gapless wear-resistant protective layer. When facing the erosion of the ore pulp 6 flow, this structure can evenly disperse the stress and avoid excessive local stress that leads to premature wear, thereby improving the overall wear resistance and protection effect and ensuring smooth flow of the fluid inside the pipe elbow.

[0025] In a preferred embodiment, the first wear-resistant layer 4 is made of wear-resistant ceramic material and is uniformly attached to the inner wall of the elbow pipe body 1. The wear-resistant ceramic material has high hardness and good wear resistance, and after being uniformly attached to the inner wall of the elbow pipe body 1, it can effectively resist the erosion and friction of solid particles in the ore pulp 6, greatly improving the wear resistance of the inner wall of the elbow pipe body 1 and significantly prolonging the service life of the pipe elbow.

[0026] In a preferred embodiment, the thickness of the first wear-resistant layer 4 is 5-15mm. This precise thickness range allows the first wear-resistant layer 4 to provide sufficient wear protection against damage caused by the erosion of the ore pulp 6 to the elbow pipe body 1, while not increasing excessive costs or affecting the overall structural performance of the pipe elbow due to excessive thickness. This thickness range has been proven in practice to achieve good wear resistance and cost-effectiveness under different ore pulp 6 conveying conditions, fully meeting the use requirements.

[0027] In a preferred embodiment, the second wear-resistant layer 5 is in the form of a semicircular tube structure, which is arranged away from the axis of the elbow pipe body 1. This arrangement conforms to the flow characteristics and wear rules of the ore pulp 6 in the pipe elbow. When the ore pulp 6 flows through the elbow, this position is more severely eroded and worn. The second wear-resistant layer 5 in the form of a semicircular tube structure can specifically enhance the wear resistance of this area, focusing on protecting the easily worn parts and further improving the wear resistance of the entire pipe elbow, thereby prolonging its service life.

[0028] In a preferred embodiment, the second wear-resistant layer 5 is made of cast stone and is covered on the surface of the first wear-resistant layer 4 by high-temperature spraying. Cast stone material has good wear resistance and self-lubricating properties, and when covered on the surface of the first wear-resistant layer 4 by high-temperature spraying, it can be tightly combined with the first wear-resistant layer 4 to form an integrated and more robust wear-resistant structure. This composite structure not only improves the overall wear resistance, but also reduces the friction between the ore pulp 6 and the inner wall of the pipe due to the self-lubricating properties of the cast stone, thereby reducing the energy loss of the ore pulp 6 flow and helping to improve the ore pulp 6 conveying efficiency, while also improving the overall service life of the pipe elbow.

[0029] In a preferred embodiment, the thickness of the second wear-resistant layer 5 is 15-20 mm, and the suitable thickness range ensures that the second wear-resistant layer 5 can provide sufficient wear-resistant performance support and further enhance the wear-resistant protection capability of the elbow. The thickness of 15-20 mm can be firmly attached to the first wear-resistant layer 4, and a good balance between material cost and actual use effect is achieved, which can meet the wear-resistant requirements and will not affect the structural design and installation space of the pipeline due to excessive thickness.

[0030] In a preferred embodiment, the bending angle of the elbow body 1 is 90° or 120°, and the bending angle of 90° or 120° can meet the common needs of pipeline turning in different ore slurry 6 conveying pipeline systems, so that the pipeline elbow has wider applicability. In the actual production layout of the mining, metallurgy, chemical and other industries, the elbow with these two angles has more application scenarios, can be conveniently and quickly connected and assembled with other pipelines, and can build a reasonable pipeline conveying network, thereby improving the universality of the product and the market.

[0031] In a preferred embodiment, the elbow body 1 is made of high-strength metal material, and the high-strength metal material (such as high-quality carbon steel) enables the elbow body 1 to withstand high pressure and high flow rate during the conveying of the ore slurry 6, and is not prone to deformation or damage, thereby ensuring the structural strength and stability of the pipeline elbow and providing stable foundation structure support for the entire wear-resistant ore slurry pipeline elbow, and ensuring safe and stable operation under various complex working environments.

[0032] In a preferred embodiment, the thickness of the elbow body 1 is 8-10 mm, which can ensure that the elbow body 1 has sufficient strength and toughness to withstand the pressure of the ore slurry 6 and external force impact, while avoiding the problems of cost increase and weight increase caused by excessive thickness, so that the elbow body 1 can achieve an optimized balance between structure, performance and cost under the premise of meeting the use requirements, which is helpful for the promotion and application of the product in the market.

[0033] In a preferred embodiment, the first flange 2 and the second flange 3 are both welded and fixed to the elbow body 1, and the welding and fixing mode enables the first flange 2 and the second flange 3 to form a firm and reliable connection with the elbow body 1, which can withstand a large external force and pressure and is not prone to separation. Compared with other connection modes, the welding connection reduces the gaps and weak points at the connection, enhances the sealing performance and stability of the overall structure, and effectively prevents the loosening or leakage of the connection from affecting the normal operation of the entire conveying system during the conveying of the ore slurry 6.

[0034] The principle and implementation mode of the utility model are described by applying specific examples, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
