DEVICE FOR EXPERIMENTAL DIGITAL ANALYSIS OF CONTENT OF MAGNETICALLY SUSCEPTIBLE PARTICLES IN FLUID MEDIUM Russian patent published in 2021 - IPC B03B13/04 B03C1/02 

FIELD: magnetic separation

SUBSTANCE: proposed invention relates to the field of magnetic separation and can be used in laboratory practice of various industries for analyzing the content (in particular, determining the concentration) of magnetically susceptible particles in a fluid medium: loose, liquid, gaseous. A device for experimental digital analysis of the content of magnetically susceptible particles in a fluid medium by the mass of particles released from a sample of the medium contains an executive magnetic separator, including a working channel limited by surfaces for the flow of the separated medium, with at least three sequentially installed sources of magnetic influence on the flow. The device also contains a means for operationally determining the actual mass of magnetically susceptible particles released from the stream by these sources, providing for the use of scales, and a system unit connected to this means for digitizing the analysis of the content of magnetically susceptible particles released with the functions of visualizing the obtained functional dependence of the operational actual masses of the released particles, extrapolating this dependence, integrating actual and extrapolated data of operational masses. Each of the sources of magnetic influence is made in the form of a non-ferromagnetic socket penetrating into the flow of the separated medium, mounted in the vertical surface of the working channel, with a magnetic block periodically placed in this socket. The scales, made on a scale commensurate with the transverse size of the socket, are located under the socket, and under its initial section adjacent to the surface of the working channel, where the released particles are discharged, which are moved to this section during the periodic removal of the magnetic block from the socket.

EFFECT: increase in efficiency of the magnetic effect on the flow of the analyzed sample of the separated medium, a reduction in time and an increase in the accuracy of the analysis.
