Synthesis of mixers with screw working elements

Abstract

The article is devoted to the problem of synthesis of mixers with screw working bodies. Alternatives were generated using the method of synthesis of hierarchical groups using morphological analysis. Moreover, as a result of the analysis of the influence of various factors on the processes of transporting and mixing materials with screw conveyors for using structural diagram synthesis using morphological analysis, the corresponding number of constituent elements of conveyor structures and the relationships between them that determine their specific design features were determined, based on which a general morphological table of design features and elements of screw mixers was compiled, which distinguishes two individual models of mechanical systems: the first concerns the generation of alternative screw conveyors, and the second involves the emergence of new design solutions for screw mixers.
During the structural and scheme synthesis of screw mixers using morphological analysis, the following main morphological features were selected: a drive, a screw, which consists of a trench and a screw working body, a hopper, a filling mechanism, an unloading mechanism, and a musculoskeletal mechanism. Using this method of synthesizing hierarchical groups using morphological analysis, a significant number of able-bodied constructions of screw conveyors with the operation of mixing and screw mixers have been developed. Structural synthesis of screw conveyors with the operation of mixing and screw mixers according to structural features by the method of hierarchical grouping using morphological analysis was carried out and a certain number of variants were generated. It is envisaged that screw mixers, as a rule, provide mixing of materials according to the cyclic principle, which will allow achieving better mixing indicators than when using screw conveyors with the mixing operation.
