Description
Technical Field
The invention belongs to the technical field of cotton production, and particularly relates to a production method of high-quality cotton linters and a device suitable for the production method.
Background
Cotton linters are cotton seeds (seeds) after embossing which have short fibers remained, and the short fibers are stripped off by a linter. Cotton linters are composed of three parts, the first part from longer fibers of the "burrs", the second part from fibers of the seeds that are broken by the cotton gin, and the third part from a layer of short, dense fibers of the cotton seed epidermis that develop naturally, which is the main component of cotton linters. The cotton yield in China is about 24% of the total cotton yield in the world, the first place in the world is occupied, the corresponding cotton linters are large in quantity, the cellulose content of the cotton linters is up to more than 90%, and the cotton linters further contain a small amount of substances such as pectin (about 1%), wax (about 2%), lignin (2-3%), ash (1%), and the like, so that the cotton linters are high-quality fiber raw materials in the artificial fiber and paper industry. The cotton linter fiber has shorter length than the lint fiber, but has equivalent maturity, so the cellulose content is high, and the cotton linter fiber is an important raw material for light industry such as national defense, textile, chemical fiber, paper making and the like, and is an important strategic material for light industry, military industry, chemical industry and medical industry.
The cotton seeds are separated by a sheller, the cotton seeds are used for oil extraction, and the rest shell is cotton seed hulls, which are also called cotton hulls. Due to different types of husking machines, different cotton seed varieties, different production places, different water contents, different sieving degrees of the crushed cotton seed powder after husking and the like. The processed cotton seed hulls are different in size, color, length of cotton velvet and cotton seed powder. At present, after the cotton seed hulls are treated, the cotton linter content of 15-40% is still not recovered, and the cotton linter is mainly used for planting edible fungus raw materials and anti-animal feed raw materials, so that resource waste is caused. Therefore, the method can effectively extract the cotton linters in the cotton seed hulls, and has good economic, social and environmental benefits. How to realize high-value efficient comprehensive utilization of cotton seed hulls is an urgent problem to be solved by us.
At present, the domestic cotton linters are generally poor in product quality, high in impurity content, high in ash content of the cotton linters, high in sulfuric acid insoluble content of the cotton linters, low in maturity of the cotton linters and 55%, and nonuniform in quality, and cannot meet the requirements of high-end products, so that the application of the cotton linters is greatly limited. The Chinese patent (CN 103103841A) finally obtains high-quality cotton linters with ash content of 0.6%, sulfuric acid insoluble matter of 3.5% and maturity of 67% through optimization of technological parameters, but the optimization of the technological parameters is limited based on the existing equipment, so that the requirements of high-end products on raw materials for producing the high-end products cannot be met by the improvement of the existing equipment in order to further reduce the production cost of downstream enterprises, therefore, the improvement of the existing cotton linter production equipment is urgently needed, the production technological parameters are further optimized, the quality of the cotton linters is improved, the production cost is saved for the downstream enterprises, and high-quality raw materials are provided for producing the high-end products.
Disclosure of Invention
Aiming at the quality problems that the sulfuric acid insoluble substance of the cotton linters obtained by the existing cotton linter production device and process is more than 8.0%, ash content is more than 2.0%, maturity is less than 55%, and the cotton linters contain three filaments and the like, the invention aims to provide a high-quality cotton linter production method and a device suitable for the same.
