Abstract
A method of recycling a filler included in artificial turf by sorting the filler into two or more materials, including: a first sorting operation of sorting the two or more materials based on a grain size; and a second sorting operation of sorting the materials, which are sorted by the first sorting operation and have grain sizes belonging to a predetermined range, based on specific gravity.
Claims17
An apparatus for recycling a filler included in artificial turf by sorting the filler into two or more materials, comprising:
- a first sorting apparatus configured to sort the two or more materials based on a grain size;
- a second sorting apparatus configured to sort the materials, which are sorted by the first sorting apparatus, and have grain sizes belonging to a predetermined range, based on the specific gravity by using centrifugal force or specific gravity difference;
- and
- a third sorting apparatus configured to sort the materials, which are sorted by the first sorting apparatus or the second sorting apparatus and have the grain sizes belonging to the predetermined range, based on specific gravity again by using vibration,
- wherein the third sorting apparatus includes:
- a table, of which at least two axes among x, y, and z axes are inclined at predetermined angles, and which reciprocates based on at least one axis among the x, y, and z axes;
- a filler supply unit provided at one side of the table to provide the materials, which are sorted by the first sorting apparatus or the second sorting apparatus and have the grain sizes belonging to the predetermined range, to the table;
- a second pressure water supply unit provided at the other side of the table different from one side of the table at which the filler supply unit is positioned to provide second pressure water having a predetermined pressure;
- and
- a collecting unit configured to collect materials which are sorted by vibration of the table and the pressure of the second pressure water and have grain sizes belonging to a predetermined range.
An apparatus for recycling a filler included in artificial turf by sorting the filler into two or more materials, comprising:
- a first sorting apparatus configured to sort the two or more materials based on a grain size;
- a second sorting apparatus configured to sort the materials, which are sorted by the first sorting apparatus, and have grain sizes belonging to a predetermined range, based on the specific gravity by using centrifugal force or specific gravity difference;
- and
- a third sorting apparatus configured to sort the materials, which are sorted by the first sorting apparatus or the second sorting apparatus and have the grain sizes belonging to the predetermined range, based on specific gravity again by using vibration,
- wherein the third sorting apparatus further includes:
- a table, of which at least two axes among x, y, and z axes are inclined at predetermined angles, which reciprocates based on at least one axis among the x, y, and z axes, and on which the materials, which are sorted by the first sorting apparatus or the second sorting apparatus and have grain sizes belonging to the predetermined range, are laid;
- a suction configured to suck the materials having the smaller specific gravities when the materials having the smaller specific gravities among the materials, which are sorted by the first sorting operation or the second sorting operation, and have the grain sizes belonging to the predetermined range, are momentarily fallen from a surface of the table when the table reciprocates;
- and
- a fine particle removing unit configured to remove fine particles irrelevant to the filler in the material having the smaller gravity sucked through the suction unit.
