| Title of the article | Design and model mixing in the apparatus with stirrer |
| Abstract. | Problem statement. Existing apparatus with a stirrer operate in a stationary mode with a large expenditure of time and energy, with insufficient homogeneity of the mixture. Reasons: the presence of zones in the body, where there is no or minimal movement of the mixed materials, a weak effect of the working organs. The aim of the study was to create devices that lacked the disadvantages of known apparatuses with a stirrer, to develop a model for mixing liquid mixtures. Results. New spatial apparatuses with a stirrer with angular variable rotation and with different laws of motion of working organs are created, the designs of which are protected by patents for inventions. The devices allow to simplify the design and significantly intensify the process of mixture formation in all technical and operational parameters. A diffusion-inertial mixing model is proposed that characterizes the concentration of the controlled component and the time of the process. Conclusions. The significance of the obtained results for mixing construction equipment is to create different groups of agitator devices that significantly reduce the mixing time of various materials, prepare mixtures of high uniformity, are simple in construction, reliable and have a high service life. |
