Embodiment Construction

[0031] Unless stated otherwise, the same reference numbers refer to the same objects in the figures.

[0032] exist figure 1 10 shows a cleaning device for removing contaminants from plastic particles, for example plastic flakes. In the example shown, the cleaning device is a disc refiner, the cleaning discs of which are indicated with reference numerals 12 and 14 . At least one cleaning disk 12 , 14 is driven in rotation by a motor 16 . Such a device is known per se and can be designed as shown in WO 2013 / 010654 A2. Although in figure 1 A disc refiner is shown, but other purification devices are also possible, such as drum or conical refiners.

[0033] A line 20 is connected to the inlet 18 of the purification device 10 , said line being connected to the outlet of an input funnel 22 . Arranged above the inlet of the feed funnel 22 is a delivery funnel 24 which forms a delivery reservoir 26 into which the plastic particles to be cleaned are injected, as indicated graphica...

Abstract

The invention relates to a device for the joint feeding of plastic particles and a liquid into a purification device (10) for the removal of impurities from the plastic particles. The device is characterized by a feed hopper (22) the inlet of which is connected to a supply for the plastic particles, and the outlet of which is connected to an inlet of the purification device by means of a supply line (20), at least one feed nozzle (38) connected to a liquid supply being arranged on the feed hopper, via which at least one liquid jet is discharged into the feed hopper, the at least one feed nozzle being arranged such that the plastic particles supplied to the feed hopper are mixed with the liquid in the feed hopper. The invention also relates to a corresponding method.

Description

technical field [0001] The invention relates to a device for jointly feeding plastic granules and a liquid into a purification device for removing pollutants from the plastic granules. The invention also relates to a method for jointly feeding plastic granules and a liquid into a purification device for removing pollutants from the plastic granules. Background technique [0002] Cleaning devices for removing contaminants from plastic particles, in particular plastic flakes (plastic flakes), are known, for example, from WO 2013 / 010654 A2 or WO 2014 / 111412 A1. In order to decontaminate the plastic granules, the plastic granules are introduced together with a liquid, usually water, into the processing area of ​​the purification device. [0003] Basically two variants are known as input methods. On the one hand, it is known to mix plastic particles into water in a separate container and to pump the suspension through a purification device by means of a solids pump. The disadv...
