Apparatus for obtaining uniform droplets

Abstract

Abstract THE DISCLOSURE RELATES TO A METHOD AND APPARATUS FOR FORMING DROPLETS OF SUBSTANTIALLY CONSTANT SIZE FROM A LIQUID, WHEREIN THE SAID LIQUID IS PASSED THROUGH A PERFORATED WALL, AND USING VIBRATIONS TO DIVIDE THE LIQUID INTO DROPLETS, THE SAID METHOD BEING CHARACTERIZED IN THAT THE LIQUID ISSUES FROM THE PERFORATIONS IN THE FORM OF LAMINARY JETS, THE PLATE IS VIBRATED AT ONE OF THE RESONANCE FREQUENCIES THEREOF, THE STATIONARY WALL IS MAINTAINED IN ONE OF ITS NODAL ZONES SO THAT IT IS CONTINUOUSLY SUPERPOSED UPON THE LAMINAR FLOW OF THE PERIODIC PERTURBATIONS WHICH DIVIDE THE JETS INTO UNIFORM DROPLETS. AMONG THE APPLICATIONS OF SAID METHOD, MAY BE MENTIONED THE MANUFACTURE OF GRANULATED CHEMICAL FERTILIZERS (PURE OR MIXED UREA-AMMONIUM NITRATE, CALCIUM NITRATE, COMPLEX FERTILIZERS, ETC.), BUT THE METHOD CAN BE USED JUST AS ADVANTAGEOUSLY IN ALL CASES WHERE IT IS DESIRED THAT SOLID GRANULATED PRODUCTS SHOULD BE OBTAINED BY THE DISPERSAL OF A LIQUID, OR A PRODUCT WHICH CAN BE SOLIDIFIED BY COOLING OR DRYING LIQUID DROPLETS (AS IN THE MANUFACTURE OF SHOT FOR INSTANCE).
