Title:
SPECIFIC GRAVITY-SPECIFIC WASTE AIR SORTER HAVING IMPURITY SEPARATION FUNCTION, USING VORTEX
Document Type and Number:
WIPO Patent Application WO/2020/166847
Kind Code:
A1
Abstract:
The present invention relates to a waste sorter using specific gravity and, more specifically, to a specific gravity-specific waste air sorter having an impurity separation function, using a vortex for sorting waste into high-specific gravity materials (PET bottles, glass bottles, cans, metals and the like), low-specific gravity materials (vinyl, paper and the like), and impurities (sand, soil, dust, glass dust and the like) when the impurities are shaken off and removed by means of the hitting of a rotating drum and vanes while the waste fed therein is turned over by a vortex. The present invention includes a main drum having radial vanes, an upper auxiliary drum, and a lower auxiliary drum, wherein the main drum is provided at one side of an input hole, the upper auxiliary drum is provided at the other side of the input hole, and the lower auxiliary drum is provided below the upper auxiliary drum, the main drum and the lower auxiliary drum rotate in the same direction, whereas the upper auxiliary drum rotates in the opposite direction, a vortex is formed between the main drum, the upper auxiliary drum, and the lower auxiliary drum in a structure of maximizing the vortex at different rotational speeds, and a screen conveyor formed in a mesh shape is obliquely provided below the input hole.
