RU95101722A - Sorting apparatus - Google Patents

Abstract

FIELD: agriculture and other branches of industry, in particular, classification of free-flowing materials by size. SUBSTANCE: sorting apparatus has two endless rod belts positioned one above the other and movable in one direction, pulleys and shafts arranged within circuit defined by two endless rod belts. Driving shaft of upper belt is positioned outside circuit defined by lower belt. Upper belt defines auxiliary sorting surface at portion between driving shafts. Process of sorting is intensified by agitators. Endless belts are made from polymeric materials. EFFECT: increased efficiency and reduced production cost.

The invention relates to techniques for the classification of bulk materials by size classes and can be used in various industries and agriculture. The purpose of the invention is to improve the quality of classification by dividing the mass into three fractions (instead of two) - small, medium and large. This is achieved by the fact that in a sorting device containing two infinite rod webs mounted one above the other and moving in the same direction with pulleys and shafts located in their contour, the drive shaft of the upper web is installed outside the contour of the lower web, while the upper web is the area between the drive shafts forms an additional sorting surface. In addition, in order to intensify the process, shakers were installed, and to facilitate and reduce the cost of the design, the sorting sheets are made of polymeric materials.
