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

Embodiment Construction

[0074] 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.

[0075] exist figure 1 with figure 2 The advantageous cutting compressor-extruder-combination for the production or recycling 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.

[0076] In the case of a small distance from the bottom surface 2, a maximum of about 10 to 20% or less of the height of the side wall 9 - measured from the bottom surface 2 up to the uppermost edge of the side wall 9 -, an orientation parallel to the bottom surface 2 is provided A flat support piece or a tool holder 13 is provided, which can be turned around a central axis of rotation 10...

Abstract

The invention relates to an apparatus for preprocessing and subsequently conveying or plasticizing plastics, comprising a container (1) with a mixing and / or comminuting tool (3) that can rotate about a rotational axis (10), wherein an opening (8) is formed in a lateral wall (9) through which the plastic material can be discharged and a multiple-screw conveyor (5) is provided with a screw (6) rotating in a housing (16). The invention is characterized in that the imaginary extension of the longitudinal axis (15) of the conveyor (5) passes by the rotational axis (10) counter the conveying direction (17), wherein the longitudinal axis (15) is on the outlet side offset by a distance (18) in relation to the radial (11) that is parallel to the longitudinal axis (15). The radial distance of the tool (mb) to the inner surface of the lateral wall (9) of the container (1) lies in the range of 15 mm to 120 mm, meeting the following relationship: mb = k * DB, wherein DB is the inner diameter of the container (1) in mm and k is a constant in the range from 0.006 to 0.16.

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 EP123771 or EP303929, 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 by the rotation of the breaking and mixing tool and brought into vibration Circulates and gets heated through by the energy added. This results in a mixture with sufficiently good thermal homogeneity. After a corresponding residence time, the mixtu...
