Problems solved by technology

However, what these patents disclose only concerns improving the efficiency of stationary classifiers (better dust removal), but does not deal with the manipulation of the classifier itself, whether the classifier is suitable for being flushed in order to avoid damage caused by the dust removal process carried out earlier. Also not mentioned is the contamination from coming dust and particles involving different particles that contaminate the current product during the dedusting process in the classifier

Embodiment Construction

[0009] The problem with the prior art is how to provide a classifier by means of which the particles can be dedusted, which classifier is not fixed at one location but can be used mobile in the facility in order to achieve different operations. At the same time, the device should be designed such that it is possible to attach the device to the silo outlet in an ergonomic manner. A further object is to set up the procedure for manipulating the device such that individual operating parameters can be set based on a number of different grader positions in a reliable and user-friendly manner.

[0010] To further solve the problems in the prior art, the present invention provides a classifier from which most of the amount of residual particles previously transported into the classifier is removed from the classifier after the dedusting process is completed. removal, and any residual particles that may still be present in the classifier, are easily and reliably washed out of the cla...

Abstract

A mobile classifier (deduster) has docking devices, flushing devices and control for the dedusting of granules, in particular polymer granules, with preference polycarbonate granules. The mobile classifier can be set up at different locations underneath silos. To perform its function, the mobile classifier is technically connected to stationary pipelines, filters and fans.

Description

technical field [0001] The invention relates to a mobile classifier (dust collector) with a pick-up device, a flushing device and a control device for controlling the dedusting of granules, in particular polymer granules , preferably polycarbonate particles. Such mobile classifiers can be placed at different locations below the silo. To fulfill its function, the mobile classifier is technically connected to fixed pipelines, filters and fans. Background technique [0002] During the production of thermoplastics, the granulated product emerging in the reactor is masticated and shaped into individual strands in an extruder with the aid of knives rotating in a pelletizing die are cut into pellets. The granulation process can be carried out, for example, in a liquid mass stream. Subsequently, the granules are dried and sieved in order to separate out agglomerates that would form even during cooling. The product is then pneumatically conveyed to a mixing silo, from which prod...
