Trial results for the production of the improved 5LP linter

Abstract

A pilot-industrial copy of an improved mixer has been developed to implement an effective process of seed raising. The manufactured pilot copy was installed on the 5LP linter in the cotton spinning workshop of the cotton spinning enterprise SANGZOR TEKSTIL LLC, Dostlik district, Jizzakh region, and the linter was improved, comparative research work was carried out with the 5LP linter with a simple construction mixer in the workshop. The studies were carried out at a distance of 8-12 mm between the saw cylinder and the mixer, selected on the basis of theoretical and practical results. During the experimental period, the quality of seeds obtained from the lint of seeds of the Bukhoro-6 variety of selection I improved by an average of 0.37 (abs)% to 0.85 (abs)%, and the quality of down improved by 0.62 (abs) % to 0.78 (abs.)%. Improving the quality of down one class higher, UzDST 645:2016 “Cotton lint. Technical conditions” type I corresponded to type B “Middle” class. Linter performance averaged 47 kg/h to 35 kg/h of seed and 2.8 kg/h to 3.4 kg/h of fluff compared to the existing 5LP linter. The quality of seeds obtained by linting seeds of the III variety of Bukhara-6 selection in the proposed 5LP linter by an average of 0.46 (abs)% to 0.38 (abs)%, the quality of fluff by 0.37 (abs)% improved by 0.25 (abs) %. Produced down is a class higher, UzDst 645:2016 “Cotton lint. Technical conditions”, type II type B was the “Middle” class. It was found that the productivity of the linter is 46-49 kg/h higher for seeds and 3.1-4.0 kg/h for linter than that of the 5LP linter with a simple mixer design. As a result of research work using an improved mixer in a 5LP linter working chamber, installing 6 mm thick rubber on metal sheets in the mixer, while pushing rubber from metal sheets to a distance of 6 mm, so as not to adversely affect the amount of oil extracted from seeds when lintering technical seeds, the distance between the rubber sheets and the saw cylinder was determined to be set at 8-10 mm, and when linting seeds, 12 mm should be left so as not to exceed the specified rate.
