Apparatus for processing plastics material

摘要

Disclosed is a device and a method for processing plastic material with at least one receiving container, wherein at least one mixing and/or comminution tool, rotatable about a rotation axis, is arranged, for mixing and warming the plastic material, and with at least one conveyor for discharging the plastic material from the receiving container, with at least one screw rotating in a housing, where the conveyor is connected, at its material inlet side via an opening which is formed in a side wall of the receiving container, with the interior of the receiving container. An imaginary extension of the central longitudinal axis of the conveyor extends, against the conveyance direction of the conveyor, past the rotation axis of the receiving container, without intersecting this axis, where the longitudinal axis of the conveyor is offset by a separation relative to the radial ray of the receiving container on the discharge side.

1. A device for treating plastic materials, comprising at least one receiving container (1) in which at least one mixing and/or comminution tool (3) which is rotatable around a rotational axis (10) is disposed for mixing and heating and, optionally, cutting and/or softening said plastic materials, wherein the at least one mixing and/or comminution tool (3) has an extreme point located at the greatest radial distance from the rotational axis (10) and wherein the extreme point located at the greatest radial distance from the rotational axis (10) defines a bounding circle when the at least one mixing and/or comminution tool (3) is rotated about the rotational axis (10), and at least one conveyor (5) for transporting the plastic materials out of the receiving container (1), said conveyor (5) having at least one screw (6) rotating in a housing (16) and, said conveyor (5) being at its material input side, connected to the interior of the receiving container (1) via an opening (8) formed in a lateral wall (9) of said receiving container (1) in order to supply or feed the material into said receiving container (1), said opening (8) being disposed at the height of the mixing and/or comminution tool (3), wherein a portion of the central longitudinal axis (15) of the conveyor (5) and the screw (6) in the direction opposite the conveying direction (17) of the conveyor (5) passes the rotational axis (10) of the receiving container (1) without intersecting it, said longitudinal axis (15) of the conveyor (5) and the screw (6) being offset in the rotational and moving direction (12) of the mixing and/or comminution tool (3), which is rotating past the opening (8), and of the plastic materials, which are transported past the opening (8), at a discharge side by a distance (18) from a radial line (11) of the container (1), which is parallel to the longitudinal axis (15) and, in the conveying direction (17) of the conveyor (5), extends outwards from the rotational axis (10) of said mixing and/or comminution (3) tool, wherein the screw (6) is outside of the bounding circle.
