Problems solved by technology

This in turn leads to agglomeration of material in this area, narrowing of the inlet cross-section and poorer feeding behavior and further to impaired throughput
In addition, melting occurs due to the increased charge pressure in this area, which again presents the previously mentioned problems
[0022] First of all for co-directed twin screw conveyors such a clogging effect is disadvantageous and avoiding overfeeding is very difficult

Embodiment Construction

[0069] In the figures, neither the container nor the auger or the mixing tool is shown to scale, nor are they in proportion to each other. For example, in reality the container is often larger than shown here, or the screw is longer than shown here.

[0070] exist figure 1 with figure 2 The cutting-compressor-extruder-combinations shown from different positions in , are very similar in their structure and are therefore jointly described below. They are firstly distinguished by the arrangement of the screws 6 relative to each other, which will be explained in more detail later.

[0071] exist figure 1 with figure 2 The advantageous cutting compressor-extruder-combination for the production or recovery of synthetic materials shown in has a cylindrical container or cutting compressor or shredder 1 with a flat, horizontal bottom surface 2 and a vertical cylindrical enclosure-shaped side wall 9 oriented normal thereto.

[0072] In the case of a small distance from the botto...

Abstract

The invention relates to an apparatus for the pretreatment and subsequent conveying or plastification of plastics, with a container with a mixing and / or comminution implement that is rotatable around an axis of rotation, wherein, in a side wall, an aperture is formed, through which the plastics material can be removed, a multiscrew conveyor being provided, with at least two screws rotating in a housing, wherein the imaginary continuation of the longitudinal axis of the conveyor in a direction opposite to the direction of conveying passes the axis of rotation, where, on the outflow side, there is an offset distance between the longitudinal axis of the screw closest to the container, on the outflow side, and the radius that is parallel to the longitudinal axis, and in that the screws co-rotate.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 . Background technique [0002] A large number of similar devices of different construction types are known from the prior art, which comprise a receiving container or a cutting compressor for shredding, heating, softening and preparing the synthetic The conveyor or extruder where the prepared material melts. The aim here is to obtain an end product of the highest possible quality and value, mostly in the form of pellets. [0003] Thus for example in EP 123 771 or EP 303 929 a device with a receiving container and an extruder connected thereto is described, wherein the synthetic material supplied to the receiving container is broken up and crushed by the rotation of the breaking and mixing tool. Bring into the vibratory cycle and get heated through by the added energy. This results in a mixture with sufficiently good thermal homogeneity. After a corresponding residence time, the...
