Pipeline for lithium battery cathode material delivery and manufacturing method thereof

Abstract

The invention discloses a pipeline for transporting positive electrode materials of lithium batteries, which comprises a stainless steel tube (3), and a ceramic tube (1) of the same length as the inner sleeve of the stainless steel tube (3), the ceramic tube (1) It consists of several short ceramic tubes (12) with the same internal and external diameters seamlessly connected in series, and the outer walls of several short ceramic tubes (12) are bonded to the inner wall of the stainless steel tube (3) by adhesive (2) . The production method of the present invention is to connect several short ceramic pipes in series through the centering mold, and then apply the adhesive to the stainless steel pipe and solidify to obtain the pipe of the present invention. The production process is simple, and the produced pipe is wear-resistant and can effectively improve The advantages such as the service life of the pipeline are conducive to improving the quality of lithium battery products.

Description

technical field [0001] The invention relates to the field of powder transportation, in particular to a pipeline used for the transportation of lithium battery cathode materials and a manufacturing method thereof. Background technique [0002] In the production process of the lithium battery industry, most of the straight line pipes currently used for powder material transportation are wear-resistant rubber pipes or PP pipes. Because rubber pipes or PP pipes are easy to wear too quickly due to the erosion of materials when conveying materials, resulting in The consequences of short-term failure are: first, frequent replacement of pipes is required, which will waste a lot of manpower, material and financial resources; second, rubber powder or pp powder after the inner cavity of the rubber pipe or PP pipe is worn will also enter the transportation Among the materials, the purity of lithium battery materials will be affected, and the quality of lithium battery materials will hav...
