Study of the operating parameters of vibrations of a vibrosieve of the washing liquid purification unit

The object of the research is elastic plates located across the movement of the solution on the vibrosieve. The problem of uniform distribution of material on the surface of the sieve is considered, which is solved with the help of the design proposed in the work. Tensometry was used as a research method with subsequent processing of the results on an elector computer. In the course of the research, an analog-to-digital converter developed and manufactured at the Department of Mechanization of Construction Processes of the National University «Yuri Kondratyuk Poltava Polytechnic» (Ukraine) was used. As well as a computer with a free COM-1 port, «PROGRAM.EXE» software and a spreadsheet editor, strain gauges in the form of strain gauges with two pasted tensor resistors connected by a half-bridge circuit. The paper proposes a fundamentally new scheme of a vibrosieve with additional working bodies in the form of elastic plates located across the movement of the solution on the sieve. The elasticity and mass of the plates are selected in such a way that their oscillations during the operation of the vibrosieve exciter are close to resonance. At the same time, the mode of vibration of the vibrosieve itself is far beyond resonance. As a result, a higher-quality and energy-efficient cleaning of the washing liquid will be obtained. This is due to the fact that the proposed cleaning method has a number of features, in particular, dispersion of drilling fluid over the entire surface of the vibrosieve and maximum loading of the entire working surface of the sieve to avoid dead zones. Thanks to this, it is possible to obtain resonant oscillations. In comparison with known analogs that work in a resonant mode, this provides advantages in the cleaning of drilling mud. The amplitude of oscillations of elastic plates reaches 1.2–1.5 mm, which is significantly greater than the amplitude of oscillations of a vibrating table. In practice, it will be possible to use the proposed fundamentally new scheme of a vibrosieve with additional working bodies in the form of elastic plates that work in a resonant mode, as a way of supplementing vibrosieves that are in use or new when manufactured at manufacturers' factories.
