Analysis of the impact effect of a piece of cotton with a flat surface with a multi-sided grates slope

Abstract

In the cotton ginning unit recommended in the article, the impact effects of multi-faceted gutters on flat sloping surfaces of cotton pieces in large waste ginning zones have been theoretically studied and connection graphs have been constructed. The results of the numerical solution of the problem, based on the analysis of the obtained analytical solutions, recommended the appropriate values of system parameters to increase the efficiency of cleaning cotton from large wastes in all three zones of the cleaning unit.

Development of a resource-saving technology allowing to increase the environmental sustainability of drying cotton raw materials

“…The studied device consists of a drying drum 1, a flange 5 mounted on rotating rollers and a support 7 that ensures smooth rotation of the flange and holds the drum firmly. The entrance part of the heat transfer network to the drum is made conical, and in the upper part there is a collector 3, a supply roller 4, and a screw drum 9 with piles at the bottom for the purpose of crushing and mixing cotton raw materials with hot air [14][15][16][17].…”
