HYDRAULIC MIXER FOR PRESERVATION COMPOSITIONS

Agricultural farms need conservation compounds to prepare equipment for storage. By heating and mixing solvent, bitumen, thickening additive and waste oil, it is possible to obtain compositions directly on the farm. This requires a compact and efficient mixer. (Research purpose) The research purpose is developing a hydraulic mixer for the preparation of a preservation composition when placing equipment for storage. (Materials and methods) Proposed a hydraulic mixer containing a tank with a three-kilowatt bottom heater, a pumping unit and a monitor with two nozzle heads. The outflow of waste oil from the outlet of the nozzle head with a diameter of four millimeters was investigated. The ratio of the oil injection pressure with a viscosity of 130 square millimeters per second to the hydraulic parameters of the head was determined. The mixer was tested in the process of heating and mixing the components of the preservation compositions. (Results and discussion) It was found that at a pressure of 0.4 megapascals, the oil consumption from the nozzle head is 255 grams per second, the flow rate is 0.75, and the kinetic energy of the jet is 64.6 joules per second. The indicators of the working process of preparing preservatives in a hydraulic mixer were clarified: productivity of 25-35 liters per hour, specific energy intensity of 0.1-0.12 kilowatt hours per liter. The equation for calculating the nominal diameter of the outlet of the hydraulic monitor was substantiated, taking into account the pump performance and drive power. (Conclusions) 270 liters of preservation compounds were prepared in the hydraulic mixer. The technological reliability of the mixer during heating and mixing of components was noted. The results obtained can be used in the introduction of hydraulic monitor mixers in agricultural farms.
