Integral wear-resistant ceramic pipe: Lithium battery industry conveying system

I. The universality and industry particularity of industrial pipeline wear problems

In the industrial production system, pipeline wear is a technical problem that various industries generally need to face. When it comes to the transportation of industrial residues, mineral particles or liquid media, pipelines inevitably bear impact and friction losses. The use of high-strength wear-resistant pipelines has become the core solution in engineering practice. In the lithium battery manufacturing industry, affected by the special production process, the problem presents a significant industry specificity.  

II. The current situation and technical bottleneck of material transportation in lithium battery industry  

Lithium battery anode materials are mostly micron-sized powder materials. Due to the particle size distribution characteristics of the powder, dust pollution is easy to occur, resulting in deterioration of the production environment, which not only increases the difficulty of manual operation and transportation management costs, but also restricts the automatic production process. The application of airflow conveying technology realizes the whole process automation of material transmission, constructs an efficient and stable production logistics system, and significantly improves the intelligent management level of the workshop.  

At present, the mainstream wear-resistant 304 stainless steel glass composite pipe gradually exposes its performance limitations in practical applications. First, the wear resistance of the wear-resistant glass pipe is insufficient. Under the continuous erosion of powder materials, the synergistic effect of chemical corrosion and mechanical wear leads to its service life of only about 6 months. Secondly, the turbulent effect caused by the sudden change of airflow direction in the elbow part of the conveying system aggravates the local wear of the bending part. Frequent replacement of conveying components not only leads to capacity loss, but also significantly increases production costs, which has become a key pain point restricting the continuous operation of production lines.  

III. The technical advantages of integral wear-resistant ceramic pipeline  

The new integral wear-resistant ceramic pipe shows significant technical superiority in material properties and structural design. The pipeline adopts high-hardness non-metallic wear-resistant materials, which has excellent wear resistance, corrosion resistance and high temperature stability. It can effectively avoid the problem of impurity introduction caused by the contact between powder materials and iron-based materials. The content of impurities such as iron in the cathode material is controlled from the material transmission link, which plays a positive role in improving the safety performance of the battery.  

IV. The specific technical indicators are as follows :

1.Service life : more than 5 times the glass pipe, greatly reducing the replacement frequency and maintenance costs ;

2.Environmental adaptability : with excellent acid and alkali corrosion resistance, it can adapt to the harsh chemical environment in the production process of lithium battery ;

3.Fluid mechanics performance : the inner wall surface roughness is low, the airflow resistance is small, and the material adhesion and transportation energy consumption are effectively reduced ;

4.Structural advantages : low density of ceramic materials, reducing the overall load of the system, reducing the operating load and maintenance frequency of the equipment ;  

5.Temperature stability : it can run stably for a long time in the ambient temperature range of 150-300 °C to meet the transportation requirements of high temperature process section.

V. Engineering application value and industry significance

In the field of industrial engineering, the optimization of anti-wear technical solutions is an important part of ensuring safe and civilized production and enhancing the core competitiveness of enterprises. For lithium battery manufacturing enterprises, the integral wear-resistant ceramic pipeline provides a solution with both advanced technology and cost-effectiveness : by extending the service cycle of the conveying system and reducing the frequency of downtime maintenance, the production efficiency is improved and the manpower and material resources are saved. The technical scheme is expected to become an important technical support to promote the development of lithium battery industry to be efficient, intelligent and green.

It is suggested that when planning the material conveying system, the relevant enterprises should comprehensively consider the medium characteristics, working conditions and life cycle cost, and give priority to the overall wear-resistant ceramic pipeline solution, so as to realize the reliability improvement and economic optimization of the production system.
