Development of experimental installation for research of technical means of mechanized technological proccesses of composition of organic waste

Abstract

Mechanized composting of organic waste involves a variety of mechanical processes, mixing, crushing of raw materials, and its refining for biological processes. The development of the desing of a universal installation for the study of mechanical processes during composting serves to solve this problem. The purpose of the work is to develop a plant that meets the requirements of the technological regulations for the mechanized preparation of compost with a wide technical capability for the study of constructive-mode praparates. The versatility of the experimental installation involves the study of various design of the beaters and working bodies of the rotary-milling type, having both of the above-mentioned organizational methods, moving the raw material and providing a working speed from 0.05 m/s to 0.5 m/s. To provide technical requirements, the elements of the frame design: sidewalls, roofs are made of slippery and joined with pulling pins. The height and width vary within 1 m. The working bodies - bits (drums) have an appropriate width of capture of 2.0 and 2.5 m and diameters from 550 (600 mm). The beaters can be installed in single or double versions with a change of departure relative to the axis by ± 300 mm. The step of the screw line varies from 250 to 350 mm. The drive of the working bodies from an electric motor. 5 kW power with a two-stage chain drive. It is planned to install an electric drive of 10 and 20 kW. The frequency of rotation of the body varies with variable stars from 140 to 700 min-1. The design of the installation allows us to study the influence of the structural-mode parameters on the farm of the extra-space space: the semicircle, trapezoidal, triangle. Technologically, this inctallation allows you to customize and simulate complex multicomponent mixtures and process parameters in a wide range of technical and economic indicators and physical and mechanical properties. As a result, an experimental installation for the study of technical means of mechanized technological processes of composting of organic waste has been developed, which allows to substantiate the operating mode of the working bodies and to select rational parameters in the development of technological regu- latio-complex multicomponent mixtures with the necessary qualitative indicators.
