Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant ceramics, in particular to a wear-resistant ceramic pipe. Background Technique

[0002] With the rapid development of the new energy industry, especially electric vehicles, in recent years, the new lithium battery materials supporting electric vehicles have also developed rapidly. Lithium battery materials have extremely high requirements for cleanliness during preparation, and the conveying pipeline is an important part of the production of lithium battery materials. Traditionally, metal pipes such as stainless steel are used, which have poor wear resistance. At the same time, the metal impurities generated during wear will affect the purity and performance of the materials, and then affect the quality of lithium batteries. There is also the use of glass materials as the lining of metal pipes, but the impact resistance and wear resistance are also relatively poor. More and more ceramic pipes are used as linings. Ceramic pipes have wear resistance, corrosion resistance, heat resistance, thermal shock resistance and mechanical shock resistance, and can effectively prevent wear or rust inside the pipeline during transportation.

[0003] When the existing ceramic pipes are actually used, the external metal pipes are easily deformed and broken due to external force impact, which is not conducive to improving safe production.

[0004] After searching the existing patents: Wear-resistant ceramic concave-convex ceramic pipe (publication number: CN209164892U), this utility model makes the installation of ceramic pipe modules more convenient and the connection more compact through the setting of the groove structure at one end and the convex structure at the other end of the ceramic pipe module, and the production is simple, the production cost is low, effectively reducing the production cost of enterprises and improving production efficiency.

[0005] Although the above patent achieves convenient installation, during the use process, the mechanical vibration generated by the external environment will impact the ceramic pipe, which is not conducive to improving the service life of the ceramic pipe.

[0006] Therefore, it is very necessary to invent a wear-resistant ceramic pipe to solve the above problems. Content of the Utility Model

[0011] As a further scheme of the utility model, the main raw materials of the ceramic inner tube are α-aluminum oxide powder and zirconia. The α-aluminum oxide powder product has high chemical stability, high purity, large true specific gravity, small ignition loss, good insulation performance, acid and alkali resistance, high mechanical strength, wear resistance, impact resistance and other characteristics. Zirconia has chemically inert properties and has the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient.

[0012] As a further scheme of the utility model, the material of the enhancement layer is carbon fiber reinforced material, and the carbon fiber reinforced material has high specific strength and specific rigidity.

[0015] As a further scheme of the utility model, the material of the reinforcement layer is glass fiber, and glass fiber has high strength and hardness.

[0017] (III) Beneficial effects

When impacted, it can reduce and absorb part of the shock feeling, thereby reducing the impact of the shock feeling on the ceramic inner pipe, avoiding the mechanical shock generated by the external environment during the use of the ceramic pipe from impacting the ceramic pipe, and improving the service life of the ceramic pipe.

[0020] 2. For this wear-resistant ceramic pipe, through the settings of the reinforcement layer and the reinforcing ribs, during use, the external metal outer pipe needs to bear the weight of the internal transported raw materials and the impact of external forces during long-term use. Glass fiber has high strength and hardness, increasing the overall stiffness. The reinforcing ribs have anti-bending properties, thereby achieving the effect of increasing the rigidity of the ceramic inner pipe and the metal outer pipe, avoiding deformation or fracture of the metal outer pipe when subjected to external force impact, and improving the safety of production.

At the same time, the inner wall of the ceramic pipe is smooth, which is conducive to the transportation of materials. In production, the raw materials can be isolated from the metal pipe, reducing the pollution of raw materials by metal impurities. BRIEF DESCRIPTION OF THE DRAWINGS
