Apparatus and Method for Segregating Contaminants from a Stream of Bulk Material

摘要

The invention relates to an apparatus for segregating contaminants (1) from a bulk material stream, wherein the apparatus has at least one inlet opening (3) for the bulk material (4), which can be connected with a bulk material feed (2), a segregating unit (5) arranged after the inlet opening (3) in a transport direction (F) of the bulk material stream, as well as at least one outlet (6) for the bulk material (4) freed of contaminants (1) with the aid of the segregating unit (5), arranged after the segregating unit (5) in the mentioned transport direction (F). According to the invention it is proposed that the segregating unit (5) has at least two transport channels (7) that are connected in parallel and branch off from the inlet opening (3), wherein the transport channels (7) respectively are passable by a bulk material partial stream that branches off from the bulk material stream flowing in via the inlet opening (3), and wherein to each one of the transport channels (7) there is allocated at least one detector (8) for the detection of contaminants (1) as well as one separating device (9), with the aid of which the bulk material partial stream passing through the respective transport channel (7) can be redirected into a disposal channel system (10). Furthermore a method for segregating contaminants (1) out of a bulk material stream with the aid of a segregating unit (5) is described, which is characterized in that the bulk material stream is divided into at least two bulk material partial streams before or within the segregating unit (5), wherein each bulk material partial stream is monitored individually with the aid of a separate detector (8) of the detector arrangement (18) with respect to the presence of contaminants (1), and wherein exclusively the bulk material partial stream comprising a contaminant (1) is redirected into a disposal channel system (10).

1. An apparatus for segregating contaminants out of a bulk material stream comprising
at least one inlet opening (3), which is connectable with a bulk material feed (2) that feeds a stream of bulk material (4), a segregating unit (5) arranged after the inlet opening (3) in a transport direction (F) of the bulk material stream, and at least one outlet (6), which is arranged after the segregating unit (5) in said transport direction (F), for the bulk material (4) which is freed of contaminants (1) with the aid of the segregating unit (5), wherein the segregating unit (5) has at least two transport channels (7) that are connected in parallel and branch off from the inlet opening (3), wherein the transport channels (7) are each passable respectively by a bulk material partial stream that branches off from the bulk material stream that flows in via the inlet opening (3), and wherein the segregating unit further has at least one detector (8) configured and arranged for detection of contaminants (1) as well as one separating device (9) respectively allocated to each one of the transport channels (7), with the aid of which the bulk material partial stream passing the respective transport channel (7) can be redirected into a disposal channel system (10).
