Problems solved by technology

If sufficiently wide and / or particularly long pipes are used (for example, in order to adopt a specific ground height of the treatment fluid column), this has the disadvantage that the retention time of the particles in the treatment fluid is correspondingly longer, which may lead to excessively strong cooling effect
However such a squeeze valve presents a significant risk or could lead to clogging of the outlet pipe, which is of course undesirable

Embodiment Construction

[0046] Fig. 1 shows a schematic diagram of a system structure with an apparatus for particle production according to an embodiment of the present invention.

[0047] Pass component B in Figure 1 (component B will refer to image 3 In further detail) represented by the plastic melt supply device, the plastic melt to be granulated is supplied to the granulation area, that is, supplied to the shredding device represented by the reference number 3 in FIG. 1. The embodiment of the shredding device 3 will refer to Figure 7 Describe in further detail. After being cut into individual pellets in the shredding device 3 or in the shredding device 3, the plastic melt then enters the treatment fluid 4 (not explicitly shown in FIG. 1), and only the flow direction of the treatment fluid is shown by the arrow , Wherein the treatment fluid is supplied to the treatment chamber 2 (not shown in FIG. 1) or to the shredding device 3 by the upstream pumping device 5, which is usually a pump, at a pressu...

Abstract

The invention relates to a device for producing granules from a polymer melt by extrusion, having a breaker plate (1), from which the polymer melt is extruded at a pressure above ambient pressure, a process chamber (2), into which the polymer melt is extruded, a breaking-down device (3) for breaking down strands of the polymer melt extruded from the breaker plate into individual granules, the process chamber being filled with a process fluid (4), and a conveying device (5), which feeds the process fluid into the process chamber at a pressure above ambient pressure, wherein downstream of the process chamber the pressure of the process fluid with the granules contained in it is reduced. According to the invention, provided downstream of the process chamber is an energy transducer (6), which at least partially extracts the compressive energy from the process fluid with the granules contained in it, thereby reduces the pressure of the process fluid with the granules contained in it and thereby converts the extracted energy at least partially into a form of energy that can be put to further use. The invention also relates to a corresponding method for producing granules from a polymer melt by extrusion and a corresponding use.

Description

Technical field [0001] The invention relates to a device for producing particles from a plastic melt according to the preamble of claim 1, the corresponding treatment according to the preamble of claim 11, and the use according to claim 13. Background technique [0002] The application field of particles produced from molten plastic by extrusion according to the present invention relates to, for example, the use of underwater hot-face processing, but is not limited to this. [0003] Another field of application in which particles are produced from molten plastic by extrusion according to the present invention is, for example, granulation of molten plastic to produce small particles, wherein the processing chamber is filled with compressed gas and a compressed processing fluid is provided in the lower area to collect the small particles. Liquid pool. The melt of the plastic material is forced through the porous plate in the upper area of ​​the processing chamber, so under the infl...
