Abstract

An apparatus for separating mixed materials of different flowability includes a frame structure, a hollow drum with a perforated peripheral surface driven in rotation and mounted on the structure, a continuous compression belt pressed against the peripheral surface from outside when wrapped around part of the drum circumference and driven in circulation, a product intake wedge formed by the belt and drum for conducting a product stream, into the apparatus between the drum and the belt in an inlet area of the product stream, and a support apparatus for the belt, with at least one support element which is arranged on the side of the belt opposite the drum, wherein the support element is configured as a roller track with at least partially spring-mounted rollers arranged successively in the conveying direction. The spring force of at least individual rollers is controllable. A corresponding method is also provided.

Dependent claims

An apparatus for separating materials of different flowability that are mixed together, comprising:

a frame structure;
a hollow drum with a perforated peripheral surface which is driven in rotation and mounted on the frame structure;
a continuous compression belt which is pressed against said peripheral surface from outside when wrapped around part of a circumference of said hollow drum and which is driven in circulation;
a detection device which detects product-specific data of a product stream as process parameters, wherein the detection device is connected to a control and/or regulating device;
a product intake wedge formed by the compression belt and hollow drum for conducting the product stream, comprising a product to be pressed, into the apparatus between the hollow drum and the compression belt in an inlet area of the product stream;
and
a support apparatus for the compression belt, with at least one support element which is arranged on a side of the compression belt opposite the hollow drum;
wherein the support element is a roller track comprising several rollers which are arranged successively in the conveying direction of the product stream and at least partially spring-mounted, the spring force of at least individual ones of the several rollers being controlled by the control and/or regulating device based on the detected product-specific data.

A method for separating materials of different flowability that are mixed together, comprising the steps:

supplying a product stream, comprising a product to be pressed, into a product intake wedge which is formed by a hollow drum with a perforated peripheral surface and a compression belt which lies on the hollow drum from outside, wrapped around part of a circumference of the hollow drum;
driving the hollow drum and/or the compression belt in circulation in order to draw in the product stream between the hollow drum and the compression belt;
and
detecting product-specific data of the inflowing product stream as process parameters by means of a detection device;
wherein more easily flowing constituents of the product stream are pressed into an inner hollow chamber of the hollow drum by means of the compression belt through the perforations of the peripheral surface of the hollow drum and discharged, while less easily flowing constituents of the product stream remain on the outside of the peripheral surface of the hollow drum and are discharged separately;
wherein on a side of the compression belt opposite the hollow drum, the compression belt is supported by a roller track as a support element, which comprises several at least partially spring-mounted rollers arranged successively in the conveying direction of the product stream,
the spring force of at least some rollers being controlled based on the detected product-specific data.
