Abstract

Inventia se refera la un procedeu pentru separarea gravitationasa, în spirala, si la un separator spiral pentru aplicarea procedeului. Procedeul prevede ca în amonte de dispozitivul de evacuare, un curent superior care contine material steril sa fie deviat spre exterior fata de un curent inferior care contine material util, curent inferior, care datorita devierii amintite, se raspandeste pe o latime mai mare. Concomitent cu deflectarea curentului superior are loc si o reumflare a curentului de steril, prin crearea unei sectiuni de trecere îngustata. Separatorul este prevazut cu niste deflectoare adiacente sau distante fata de peretele interior al jgheabului, pozitionate la circa 50..200 mm în aminte de dispozitivul de evacuare si cu niste deflectoare prevazute pe peretele exterior al jgheabului.The invention relates to a process for gravitational separation in the spiral and to a spiral separator for applying the process. The process provides that upstream of the evacuation device, a higher stream containing sterile material is diverted outwardly from a lower current containing beneficial material, lower current, which, due to the abovementioned deviation, spreads over a larger width. Concurrently with the deflection of the upper current there is also a rewinding of the waste stream by creating a narrow passage section. The separator is provided with some baffles adjacent to or spaced from the inner wall of the gutter, positioned about 50 to 200 mm in memory of the exhaust device and with some deflectors provided on the outer wall of the gutter.
