Self-cleaning filter based on magnetically controlled particles

Shorstkii Ivan A., Savenkov K.Yu

The main problems of sedimentation using and control to improve efficiency of filtration process are discussed. To solve the problem of precipitation a new machine design is proposed and the principle of the self-cleaning filter operation, based on magnetically controlled particles, is described. As a basic mechanism for machine design a method of particles array structure control by external rotating magnetic field is proposed. The results of research show the possibility of creating a dynamic porous filter cake structure with close packing of particles, as well as the self-cleaning process of filter machine, that does not require additional engineering communications. Based on the X-ray analysis data the composition of the microparticles of filter cake is defined as Iron Oxide Fe3O4. SEM-images of porous structure of the filter cake were obtained using a scanning electron microscope. Results of current work serve as the basis for conducting further researchers related to determining the functionality parameters of filter machine, as well as confirming or refuting the hypothesis of the influence on the quality of food media when their passing through the filter cake with a dynamic porous structure.
