Improving the efficiency of grain cleaning equipment from the harmful effects of dispersed dust

Abstract

Ways to increase the efficiency of grain cleaning equipment in agricultural production are considered.
The aim of the work is to increase the efficiency and efficiency of equipment for harvesting and processing of cereals by completing cleaning systems: electrostatic filter of diesel fuel, the use of a rotary cyclone from the harmful effects of dispersed particles.
Increasing the durability and productivity of grain harvesting equipment and grain cleaning machines is one of the most important problems of modern development in the industry, because the simple equipment during harvesting and processing of grain products is associated with large economic losses. The technical aspects of its solution are, along with design developments that provide the necessary increase in efficiency of equipment, improving the quality of the obtained grain material and fuel lubricants. To achieve this goal, methods of purification from solid dispersed particles are proposed. From the existing cleaning agents that increase the efficiency of agricultural grain cleaning equipment, it is necessary to choose the optimal ones that give the maximum effect in the operating conditions of modern APV at minimum costs.
The article presents methods of different principle of operation with aftertreatment systems for grain cleaning separators and the use of diesel fuel purification filters that use a heterogeneous electric field.
According to the results of production tests of the rotary cyclone, the efficiency of the process of cleaning grain mixtures from dispersed dust particles by 30…35 %, and increase the productivity of mobile grain separators by 20… 23.2 %. The application of the developed system of purification and preparation of diesel fuel showed the possibility of increasing the resource of fine filters by 5 times while increasing the resource of plunger pairs of pumps in 2 times.
