Problems solved by technology

However, the current domestic cotton linter production generally has poor product quality and high impurity content. The ash content of cotton linters is greater than 2.0%, the sulfuric acid insoluble content is greater than 8%, and the maturity is less than 55%. At the same time, the quality is not uniform and cannot adapt to The need to produce high-end products, thus greatly limiting the use of cotton linters

Embodiment 1

[0021] Embodiment 1: The specific process steps of the production method of this high-quality cotton linters are as follows.

[0022] 1000kg of wool cottonseed is fed into the feeding system, and the material passes through triple sieve, wind seed cleaning machine and stone remover in sequence to remove all solid impurities, foreign fibers and most of the dust in it to obtain de-impured cottonseed. Send the delint cottonseed into the delint machine for delint, by controlling the gap between the saw blade and the shifting roller to be 3mm, and the speed ratio to be 1:60, to obtain the low-impurity cotton linters with an impurity content of 6wt%. velvet. The low-impurity cotton linters are sent into the linter collection machine by wind power. The diameter of the inner cylinder of the collection machine is 58 mesh, and the rotation speed of the cylinder is 40r / min to obtain dust-removing cotton linters with an ash content of 1.2wt%. The dedusted cotton linters enter the husk an...

Embodiment 2

[0023] Embodiment 2: The specific process steps of the production method of this high-quality cotton linters are as follows.

[0024] 1000kg of wool cottonseed is fed into the feeding system, and the material passes through triple sieve, wind seed cleaning machine and stone remover in sequence to remove all solid impurities, foreign fibers and most of the dust in it to obtain de-impured cottonseed. Send the delint cottonseed into the delint machine for delint, by controlling the gap between the saw blade and the shifting roller to be 8mm, and the speed ratio to be 1:80, to obtain low-impurity cotton with an impurity content of 5.5wt% in cotton linters linter. The low-impurity cotton linters are sent into the linter collection machine by wind power. The diameter of the cylinder inside the collection machine is 55 mesh, and the rotation speed of the cylinder is 50r / min to obtain dust-removing cotton linters with an ash content of 1.1wt%. The dust-removed cotton linters enter th...

Embodiment 3

[0025] Embodiment 3: The specific process steps of the production method of this high-quality cotton linters are as follows.

[0026] 1000kg of wool cottonseed is fed into the feeding system, and the material passes through triple sieve, wind seed cleaning machine and stone remover in sequence to remove all solid impurities, foreign fibers and most of the dust in it to obtain de-impured cottonseed. Send the de-linted cottonseed into the delint machine for delint, by controlling the gap between the saw blade and the shifting roller to be 2mm, and the speed ratio is 1:50, to obtain low-impurity cotton with an impurity content of 6.5wt% in cotton linters linter. The low-impurity cotton linters are sent into the linter collection machine by wind power. The diameter of the inner cylinder of the collection machine is 50 mesh, and the rotation speed of the cylinder is 30r / min to obtain dust-removing cotton linters with an ash content of 1.3wt%. The dedusted cotton linters enter the ...

Abstract

The invention discloses a manufacturing method for high-quality cotton linter. The processing steps includes that (1) gross cottonseeds of raw material of the cotton linter are purified, stone and dust in the gross cottonseeds are eliminated, and the purified gross cottonseeds are obtained; (2) the obtained purified gross cottonseeds are sent to a delinter to have linter peeled and the impurity content of the purified gross cottonseeds is controlled, so that the cotton linter with low impurity is obtained; (3) the cotton linter with low impurity is sent to a lower linter collecting machine to have the dust eliminated, and the dedusted cotton linter is obtained; (4) the dedusted cotton linter is sent to a shell-linter separator where the linter is effectively separated from the impurities, and the cotton linter without impurity is obtained; (5) the cotton linter without impurity is sent to a cleaning machine where the linter is further separated with the impurities, and the high-quality cotton linter is obtained. According to the manufacturing method for the high-quality cotton linter, the gross cottonseeds are preliminarily purified, the cotton linter with the low impurity content is obtained through the delinter, and then the lower linter collecting machine, the shell-linter separator and the cleaning machine are utilized in sequence, so that the impurities and the dust in the cotton linter are eliminated, and the cotton linter which is low in dust content and impurity content, high in quality and even in mass distribution is obtained.

Description

technical field [0001] The invention relates to the field of cotton linters processing technology, in particular to a production method of high-quality cotton linters. Background technique [0002] Cotton linters are important raw materials for light and chemical industries such as national defense, textiles, chemical fibers, and papermaking, and are important strategic materials. my country is rich in cotton, and the cotton linter resources are very rich. However, the current domestic cotton linter production generally has poor product quality and high impurity content. The ash content of cotton linters is greater than 2.0%, the sulfuric acid insoluble content is greater than 8%, and the maturity is less than 55%. At the same time, the quality is not uniform and cannot adapt to The need to produce high-end products therefore greatly limits the use of cotton linters. Contents of the invention [0003] The technical problem to be solved by the present invention is to prov...
