Determination of Parameters of Grates on Rubber Brackets of Fiber Material Cleaners

Abstract

The article shows the installation scheme of the grate and the principle of operation of the cleaner of fibrous material from large litter. The oscillation of the grates installed in the upper and lower cleaning zones with different thickness of the rubber support was studied. On the basis of theoretical studies of the grate in the form of a single-mass system, regularities of the change in vertical mixing and speeds of grates are obtained. Graphical dependences of the change in the amplitude of oscillations of the mixes and the speeds of the grate are constructed on the variation of the mass of the grate, the disturbing force on the cotton being revealed, and also on the stiffness coefficient of the elastic support. Full-factorial experiments obtained regression equations. By solving the problem, graphical dependencies of the change in the cleansing effect on incoming factors are constructed. The analyzes substantiate the parameters of the fibrous material cleaner.
