Development and Substantiation of Parameters of An Effective Device for Removing Fibers from the Lower Part of the Saw Gin

Abstract

The article is developed a scheme for the construction of equipment for removing fibers separated from saw teeth in saw gin, removing fibers from the bottom with air based on the analysis of their structures. The advantages and disadvantages of existing constructions have been studied. Comparative comparisons are given. The air consumption that occurs in the device, the velocity, as well as the coverage of the space between the surfaces of the pipe and the saw cylinder by the forced air at a large angle, the air velocity gaps formed between the outer surface of the saw and the grate-bar, factors that reduce efficiency when removing fibers from the saw teeth are considered. The air consumption that occurs in the device, the speed, as well as the coverage of the space between the surfaces of the pipe and the saw cylinder by the forced air at a large angle, the airspeed gaps formed between the outer surface of the saw and the grate-bar, factors that reduce efficiency when removing fibers from the saw teeth are considered. The parameters of the air chamber, visor, guide tube and receiver tubes mounted on the saw gin's bottom fiber stripping device have been studied. Theoretical studies have obtained a mathematical model that represents the movements of fibers in the removal of air from the saw teeth, the laws of motion of fibers in coordinate terms have been determined. Link graph analysis has determined the recommended values of fiber stripping zone parameters
