DETERMINATION OF THE SEDIMENT EROSION AREA PARAMETERSIN THE MANURE STORAGE BY THE DIRECTEDACTION OF A LIQUID MANURE JET

Abstract

When liquid manure is stored in manure storage facilities, it is divided into fractions with the deposition of a heavy fraction into the sediment. The erosion of the manure sediment is one of the most important indicators of the process of mixing the manure mass in the manure storage. Insufficient erosion of sediment leads to a decrease in the fertilizing properties of organic fertilizers, as well as a decrease in the useful volume of manure storage.

The size of the sediment erosion area depends on the velocity of the manure mass jet created by the agitator, the volume of manure sediment accumulated during storage and the structural and kinematic parameters of the mixer. The
relationship between the depth and length of the segment erosion section, the mixer design parameters, the physical and mechanical properties of the manure, as well as the distance of the erosion section from the casing nozzle and the orientation angle of the casing jet-forming nozzle has been established. The article presents the results of theoretical research of determination of the geometric parameters of the manure sediment erosion site in the manure storage with a mixer equipped with a casing with a cone-shaped nozzle.
