Abstract
Abstract THE WASTE SEPARATOR INCLUDES A SEPARATOR WHICH CONSISTS OF A FABRIC FILTER TO FILTER OUT THE WASTE INTO A HELICAL WORM WHICH ROTATES BETWEEN THE SEPARATOR AND DETACHABLE WASTE CONTAINER. THE HELICAL WORM TRANSFERS THE WASTE INTO THE CONTAINER AND THEREAFTER COMPRESSES THE WASTE IN THE CONTAINER. THE CONAINER CAN BE MOUNTED ON AN ELASTICALLY DEFORMABLE PLATE WHICH PERMITS THE WASTE WEIGHT IN THE CONTAINER TO ACTIVATE A SWITCH BELOW THE PLATE FOR SHIFTING THE AIR FLOW INTO ANOTHER WASTE SEPARATOR.
