ARTICLE ANNOTATION

quote
The article provides information on improving the quality of products and reducing emissions of cotton dust into the environment at cotton gin plants. In this regard, to improve the environmental situation, it becomes an important factor in carrying out research work to improve cotton processing technology and its scientific basis. In particular, it is necessary to determine the model of connections for transporting and cleaning cotton, determine the parameters of means for removing impurities and dust from cotton, and change the technology for moving and cleaning cotton during transportation. In this direction, in order to save energy and resources, special attention is paid to the development of machines and devices with harmonized technological processes, as well as the scientific substantiation of their parameters and operating modes. For this purpose, the ShH type cotton transportation conveyor has been improved to remove impurities and dust at the initial stage of cotton processing. Theoretical studies have been carried out to study the speed of movement of the cotton flow in an improved device for transporting and cleaning cotton. Based on theoretical research, the law of distribution of speed and density of cotton flow on a screw conveyor was determined. It was observed that the flow velocity and density decreased across the cross section with a decrease in the volumetric compressibility modulus. Based on the results of this calculation, the following conclusions were drawn. At external pressure 0 (zero) in the first section of the conveyor, the speed and density periodically change evenly along the screw pitch at maximum and minimum.
