Embodiment Construction

[0029] The cylindrical drum 1 is mounted in a housing 11 and rotated by a drive 12 , wherein the axis of rotation 3 runs slightly obliquely to the horizontal.

[0030] Furthermore, the drum 1 is perforated, wherein fine-grained components flow through the perforations and coarse-grained components or waste with larger impurities are blocked by the perforations.

[0031] Below the drum 1 there is a collection container 13 for containing the fines fraction. Above the drum 1 jets can be arranged which direct the water at the perforations. This cleans the perforations and also further dilutes the fiber material 2 inside the drum 1 .

[0032] In this case, the first end face 4 of the drum 1 is closed and the axially opposite second end face 5 is open.

[0033] In the upper region of the inner space of the drum 1, the fibrous material 2 to be treated is conveyed via the second open end face 5 of the drum 1 to the first end face 4 of the drum 1 via an axially extending conveying du...

Abstract

The invention relates to a rotary drum (1) for processing fibrous material (2), the drum's axis of rotation (3) being inclined at a maximum of 30° with respect to the horizontal, on a first end face (4) mixed with water The fiber material (2) is fed into the drum, and the fiber material is transported inside the drum (1) from the first end face (4) to the second end face (5) by means of the conveying element (6), wherein the drum (1) There are perforations through which the fine-grained components flow and the coarse-grained components are blocked by the perforations. Here, the treatment of the fiber material is enhanced in that the first end face (4) of the drum (1) is closed and at least one blocking nozzle (9) diverts the water jet from the direction of transport (10) of the fiber material (2) Inversely align the fiber material (2).

Description

technical field [0001] The invention relates to a rotary drum for processing fibrous material, the axis of rotation of which is inclined at a maximum of 30° relative to the horizontal, into which drum a fibrous material mixed with water is fed on a first end face, the fibrous material being fed in the drum The interior is conveyed from the first end face to the second end face by means of conveying elements, wherein the drum is perforated through which the fine-grained components flow and the coarse-grained components are blocked by the perforations. Background technique [0002] With such a device, which is described, for example, in DE 10 2012 219 708 A1, the contaminated waste paper is mixed with water, shredded and sieved in many cases. For this purpose, the water-laden waste paper is comminuted by lifting, sliding and falling of the material components or by relative movement of the material components relative to each other in the disintegration zone of the generally h...
