Design And Application Study Of Magnetic Levitation Dispersion Instrument

It is proved by many theoretical and experimental results that the magnetic field can make significant influence to most chemical reactions (eg. photochemical reactions, polymerization reactions and chemical reaction involving transition metal elements). Synthesized material in a magnetic field can reflect the special mechanical, optical, and electrical properties. Chemical reactions and material synthesized has becoming the focus for reseachers. But the current study is limited to analysis of chemical synthesis and material properties which in the existing magnetic field magnetizing machine or a small permanent magnet magnetic field, and lack of magnetic field which suitable for chemical experiments and material synthesis.At present, in the magnetic material synthesis experiments, it is difficult to ensure the purity of the product, and after the magnetic composite material synthesis, it is difficult to ensure the purity by general filtration method because there is a special magnetic material magnetic interactions. Most laboratories still extract resultant by simple permanent magnet, this method is dangerous, maneuver, and difficult to fully separate the mixture. Secondly, many reaction conditions required in a sealed, vacuum or nitrogen, while the existing experimental apparatus is difficult to meet these requirements. It brings a lot of inconvenience to the operator. In addition, the stirring is most important action in reaction, but most of the metal particles have large density, so the solution mainly in the bottom of the solute, resulting in bottom of a liquid solute concentration greater than the concentration in the upper part when in rotary stirring because of the solution concentration difference. It is not conducive to the further dissolution of the solute.It is can be seen that the face of the magnetic field continues to expand, because the magnetic field itself is not more innovation and breakthroughs, we can not place most of the chemical, materials science and biology subjects in a magnetic field to continue this reseach because the magnetic field itself haven't so much innovation and breakthroughs when we face the expansion of the research in magnetic field. So the further expansion has been limited. Therefore, we need a way to provide particles fully dispersed in solution, effectively reducing the concentration difference, while the particles can be screened for the synthesis of magnetic separation equipment. From the electromagnetic theory, this article introduces the magnetic field generation mechanism from electromagnetic theory, and designs the basic magnetic field configuration, draws the 3D and CAD picture of magnetic instrument; The most suitable conditions for the magnetic device is calculated based on the classical theory of magnetism; The magnet pole coil performance is enable to adjusted to provide continuous DC uniform electromagnetic field according to electromagnetic design principles; The magnetic field of ferroelectric materials and appearance parameters are also adjusted to fit rectifier and cooling equipment according to the long chemical reaction time and the different characteristics of reactor. In the end, we produce synthetic instrument magnetic dispersion model, test, debug and validate design data combined with theory data, also we discuss the use of this instrument in the fields of material synthesis, product separation, and wasted water treatment based on the disign of magnetic dispersion synthesizer.
