Technological process and apparatus for delinting of cotton seeds

Abstract

The technological process of delinting cotton seeds features that cotton seeds are first delinted mechanically in a mechanical delinting device, then sprayed with certain amount of foamed dilute sulfuric acid, stoved in the stoving room and polished in one other mechanical delinting device, and finally washed. The mechanical cotton seed delinting apparatus includes rolling steel wire brush, sieving plate, lint extracting cover, and features the rolling steel wire brush and the sieving plate vertically set, the sieving plate with valve, and the delinting chamber with material inlet in the upper end and material outlet in the lower end. The mechanical cotton seed delinting apparatus has reasonable structure, good cotton seed flowability, high efficiency, low power consumption and other advantages.

Description

1. Technical field [0001] The invention relates to the processing of cotton seeds, in particular to a cotton seed delinting process. The invention also relates to a mechanical delint device used for realizing the process. 2. Background technology [0002] Cotton is an important economic crop, and the processing of cotton seeds is an indispensable link in the cotton planting industry. The harvested seed cotton goes through the pricking process, and the lint and cottonseed are separated. The pricked cottonseed generally has 6-7mm short fluff. This kind of fluffy cottonseed cannot be directly used as seeds, and usually needs to be delinted. At present, the cottonseed delinting process method is: the cottonseed with short staples is sprayed with dilute sulfuric acid and mixed well, then enters the centrifuge, dries up, and recovers the acid solution at the same time, the dried cottonseed enters the drying room, and the acid-etched cottonseed after drying , the linters on the s...

AI Technical Summary

Problems solved by technology

The disadvantages of the above process method are: more acid is consumed, the waste produced is not conducive to environmental protection, the linters on the cottonseed cannot be recycled, and in the process of processing, there are many procedures and the drying process consumes a lot of energy.

The main problems in the actual application of this patented technology are: low production capacity and cumbersome maintenance, therefore, it has not been promoted

From its structural analysis, its main working parts, the steel wire brush roller and the sieve plate, are placed horizontally. The machine is in a horizontal state. From the entrance to the exit, the cottonseed with cashmere goes through a zigzag path after secondary delinting. , the whole process, the cottonseed with velvet flows horizontally, and the fluidity of the cottonseed is not good, which directly affects the productivity. Second, because the ends of the steel wires on the steel wire brush rolls must be regularly ground, its steel wire brush rolls need to be dismantled, refurbished, and repaired. Very inconvenient
