Abstract
The article examines pneumatic transport, one of the main functions of equipment in the sequence of technological processes in ginneries, and gives the main performance of equipment in the pneumatic transport system. Also, the efficiency of the process of transporting cotton in a pneumatic transport device, time of transportation, the share of raw cotton in the internal volume of the air pipeline during transportation and processes in the pneumatic transport system were analyzed on the basis of theoretical and practical experience.
Highlights
Preliminary processing of cotton in the technological process requires the improvement of technological processes through the application of in-depth research to the production of efficient designs of pneumatic transport devices [1]
Analyzing the results obtained (Fig. 1), when transporting cotton by pneumatic transport, if it is assumed that the cotton is transported evenly, the cotton occupies only 18 ÷ 23% of the pipe volume when spread along the length of the air pipe
An increase in the cross-section of the air duct at the same air velocity leads to a large increase in air consumption, and to a decrease in power consumption, and a decrease in air consumption and power
Summary
Preliminary processing of cotton in the technological process requires the improvement of technological processes through the application of in-depth research to the production of efficient designs of pneumatic transport devices [1]. The pneumatic transport elements of raw cotton, as well as the laws of movement within the air duct have been studied at different levels [9,10]. If the initial transfer rate of the raw material is v0 and the velocity in any section of the air duct is v, the following equation is valid in the stationary transfer mode: 1− m = (1− m0 ) v0 0 / v
