Analytical research into the motion of organic mixture components during formation of compost clamps

Abstract

Effective way of improving the level of plant production is composting. Therefore, it is a relevant task to create energy-saving equipment and related technologies for the production of composts while providing effective fermentation under conditions of agricultural enterprises. However, at present, there are no machines and equipment in Ukraine for composting the organic raw materials. In addition, dependences of relationship between design and kinematic parameters of working bodies of the appropriate machinery and parameters of clamps have not been explored properly. In order to conduct analytical studies into the process of work of a clamp turner, we applied the method of analytical modeling of its operation process. To form the clamps of compost and their aeration, we proposed working bodies in the form of a drum with a radial arrangement of blades. An analytical model of drum with a radial arrangement of blades is proposed. The model makes it possible to establish the character of motion of compost particles depending on geometrical parameters of the drum and the kinematic indicators of performance. We found the absolute flight velocity, initial throwing angle of compost particles and the time of compost particles motion before leaving a blade. Developed analytical model makes it possible to set the parameters for loading and unloading the drum blades within a wide range of values of design and technological parameters. Based on the analysis of the model proposed, it can be argued that in order to control a clamp height, it is necessary to change the kinematic indicators of drum performance. Results of the research reported here theoretically confirmed working ability of the designed equipment; however, it needs to be tested under industrial conditions. Further studies should be conducted in the direction of examining the influence of equipment parameters on the reduction in energy costs in the production of composts.
