Abstract

A separation apparatus (1) for separating fractions of contaminant (1a, 1b) from a liquid flow comprising a heterogeneous mixture (100), it comprises a separation tank (2) comprising: the first external lateral wall (3); a second external lateral wall (6) opposite the first external lateral wall (3); a bottom (9); a first inlet (12); a second inlet (13); a first outlet (14) for the first fraction of contaminant (1a), between the first inlet (12) and the second inlet (13); a second outlet (15) for the second fraction of contaminant (1b); a third outlet (16) for the liquid flow of which the heterogeneous mixture (100) has been cleared of the first fraction of contaminant (1a) and of the second fraction of contaminant (1b); a first internal lateral wall (17) which forms a first passage (18); a second internal lateral wall (19) which forms a second passage (20); defined in the separation tank (2) are: a first volume (21) and a second volume (22). Further, the separation apparatus (1) comprises dispensing means of a fluid (23) which are arranged so as to dispense a fluid into the second volume (22) and to set off, during the use of the separation apparatus (1), a plurality of motions (101, 102) thus determining in the second volume (22) the floating of the first fraction of contaminant (1a) and the settling of the second fraction of contaminant (1b); a first plurality of scrapers (24) and a second plurality of scrapers (25) to draw the first fraction of contaminant (1b) towards the first outlet (14).

Abstract

A substantially vertical separating column of a waste-product treatment apparatus has a cylindrical body with holes in a lateral surface, inferiorly of a waste-product supply opening. A bladed shaft rotates coaxially inside the cylindrical body. A first discharge mouth in an upper part of the cylindrical body expels a first waste-product recycling fraction, the fraction separated and transported upwards by the bladed shaft. A dilution group along the separating column supplies dilution liquid internally of the cylindrical body. A second discharge mouth in the lower part of the cylindrical body evacuates a second recycling fraction. A discharge conduit and a screw extend parallel to a tangent to the cylindrical body, facilitating extraction of the first recycling fraction to the discharge conduit. The bladed shaft comprises a rotor and, in proximity of the upper end, a plate fixed to a lateral rotor surface and arranged radially.

Abstract

A treatment apparatus of a waste product (1 ) for separating recycling fractions, comprising: a separating column (2) arranged substantially vertically, comprising a cylindrical body (3) provided on the lateral surface thereof with a plurality of holes and inferiorly of an opening (5) for supply of a waste product to be treated, and a bladed shaft (4) activated in rotation by a first motor and positioned coaxially internally of the cylindrical body (3); a first upper discharge mouth (6) arranged in an upper part of the cylindrical body (3) for expelling a first recycling fraction present in the waste product subjected to the treatment, which first recycling fraction is separated and transported upwards by the bladed shaft (4); a discharge group (7) for extraction of the first recycling fraction; a dilution group (8) positioned along the separating column (2) for supplying water or like dilution liquids internally of the cylindrical body (3); a second discharge mouth arranged in the lower part of the cylindrical body (3) for evacuating a second recycling fraction. The discharge conduit (9) and the screw (11 ) are arranged parallel to the tangential direction with respect to the cylindrical body (3), so as to facilitate extraction of the first recycling fraction from the cylindrical body (3) to the discharge conduit (9) and the bladed shaft (4) comprises a first rotor (40) and, in proximity of the upper end, at least a plate (45) fixed to the lateral surface of the first rotor (40) and arranged radially.
