[0002] As we all know, in the rubber production process, carbon black is a key raw material for enhancing the plasticity of tires. In the production process, pneumatic conveying is used to pressurize carbon black from a sealed pipeline into a storage tank. In order to prevent leakage accidents during the pipeline transportation process, the carbon black delivery pipeline is composed of an aluminum alloy outer pipe and an inner lining hose. During the carbon black transportation process, the carbon black rubs against the inner lining hose, and the hose wears and leaks, blocking the pipeline. The production pressure is stopped, and the pipeline needs to be disassembled to replace the inner lining hose. When installing the hose joint, the hose flange needs to be compacted to ensure the sealing performance of the pipeline. Special tools and installation processes are required to complete the replacement and repair work. The equipment cost is high and the operation steps are complicated. Summary of the invention
