EQUIPMENT AND METHOD FOR COLLECTING MICROPLASTICS FROM DRY BEACH SEDIMENTS

The invention relates to an equipment meant for removal of microplastic particles contained in dry sediments on the beaches in the coastal area, deposited due to the action of wind, water streams and waves and to a method for using the claimed equipment. According to the invention, the equipment consists of a chassis (A) provided with wheels, which can be hauled by an independent transportation means, on which all the equipment components are mounted: a collecting blade (1), a rotary cylinder (2), a system of three screens (3) for separation of elements of different sizes which will be stored in a microplastics collecting container system (4), the screen system (3) being mounted on a vibrating plate (5), and a module (E) for electrostatic separation of the screened sediment, where all the moving components (C, G and H) of the equipment are put into motion by the kinetic energy of the running gear (B). The method for using the equipment, as claimed by the invention, involves the sediment separation from anthropic objects during the travel of the equipment, the sediment being taken from the field by a collecting blade (1) which feeds the sediments to a rotary cylinder (2) while aerating it, after which the sediments are sent to the screen system (3) where the macro wastes are eliminated in the microplastics collecting container system (4), the material resulting from the screening process being taken over by the electrostatic separation module (E) where the microplastics particles are concentrated on the surface of the positively polarized metal plates wherefrom they may be recovered and the resulting sediment material is returned to the nature. Invenţia se referă la un echipament destinat îndepărtarii particulelor microplastice conţinute de sedimentele uscate aflate pe plajele din zona costieră, care au fost depozitate prin intermediul acţiunii vântului, curenţilor de apă şi a valurilor şi la o metodă de utilizare a echipamentului. Echipamentul conform invenţiei este constituit dintr-un şasiu (A) prevăzut cu roţi care poate fi tractat de un mijloc de transport independent, pe care sunt montate toate elementele constitutive ale echipamentului, respectiv o lamă (1) colectoare, un cilindru (2) rotativ, un sistem (3) de trei site pentru separarea elementelor de diferite dimensiuni care vor fi depozitate într-un sistem (4) de recipiente de colectare a microplasticelor, sistemul (3) de site fiind montat pe o placă (5) vibratoare şi un modul (E) de separare electr
