Description

Technical Field

[0001] The utility model relates to the technical field of lignin production, in particular to a lignin fiber raw material separation device. Background Art

[0002] Lignin fiber is an organic fiber obtained by chemical treatment using bamboo or natural wood as raw materials. It is usually cotton-like and white or grayish white in color. Lignin fiber is chemically very stable and can remain stable at temperatures up to 250 degrees Celsius. It is not easily corroded by general solvents and acids and alkalis. It is also non-toxic, odorless, pollution-free, and non-radioactive. These characteristics make lignin fiber widely used in asphalt, roads, concrete, mortar, gypsum products, wood pulp, sponges and other fields.

[0003] The raw materials used in the production of lignin fiber are mostly the leftover waste from the production of wallpaper from cotton mills. Since the waste is recycled, it is inevitable that the raw materials contain a lot of non-cotton lint debris. Among them, the mixed blocky garbage will cause unstable quality if it is directly put into the production system. Utility Model Content
