Abstract

The invention effects recycling of paint sludge from 1-component paints which has not been unstuck with adsorbents or coagulants. The solvent-containing paint sludge adhering to the board fabric belt runs over a flat table surface and the adhering paint is scraped off from the broad fabric belt by means of a doctor blade and, via a kneader, the paint passes into a collection vessel. It can be reprocessed there. The broad fabric belt returns via a reversing roller into a solvent container and is there washed by brushes and the paint residues are removed. The belt is then rolled up again and can be reused at any time. This process effects a recovery of high-value paint completely without cost.

Description

Die Erfindung, Verfahren und Vorrichtung zur Entsorgung von nicht oder schwer entklebbaren Lacken aus Naßlackieranlagen und Farbspritzständen und anderen Industrieschlämmen, aus Klär- oder sonstigen Reinigungsanlagen, ermöglicht, daß auch nicht mit Adsorptions- und Koagulierungsmittel entklebter Lackschlamm, sondern reine und nur lösemittelhaltige Farbpartikel sich auf dem Gewebe- Breitband (1) durch Sedimentation absetzen oder flotierende Farbpartikel ohne Koagulieruangsmittel an der Oberfläche von dem Gewebe-Breitband (1) am Beckenrand erfaßt und ausgetragen werden. Dieser reine Farbschlamm, ohne Adsorptions- und Koagulierungsmittel kann daher der Wiederverwendung zugeführt und im nachstehenden Recyclingverfahren vollwertig aufbereitet werden.The invention, method and device for the disposal of paints which are not or are difficult to detack from wet painting systems and paint spray booths and other industrial sludges, from clarifiers or other cleaning systems, make it possible for paint sludge not to be detackified with adsorbents and coagulants, but for pure and only solvent-containing paint particles settle the tissue broadband ( 1 ) by sedimentation or floating color particles without coagulant on the surface are detected and discharged by the tissue broadband ( 1 ) at the pool edge. This pure color sludge, without adsorbents and coagulants, can therefore be reused and fully processed in the recycling process below.

Das mit reinem Lackschlamm befrachtete Gewebe-Breitband (1) gelangt nicht nach der Berieselungswasser-Entsorgung in den Abfallcontainer, wie im Hauptpatent mit koaguliertem Lacksschlamm vorgesehen, sondern wird in ganzer Breite durch die Nadel-Abzugs­ walze (6) weiter transportiert über die Flachabdeckung (15) des Lösemittelbehälters, die als Tisch dient. Auf dieser Flachab­ deckung (15) ist in Schrägrichtung ein Abstreifer (16) aus Gummi, Kunststoff oder anderen Werkstoffen befestigt, der den auf dem Gewebe-Breitband (1) aufsitzenden reinen Lack nach der Seite hin abstreift und über einen Kneter (18) dem Farbsammel-Behälter (17) zuführt. Dieser Kneter (18) trennt das anhaftende Wasser vom Lack, so daß nur reiner Lack in den Farb-Sammelbehälter (17) gelangt. Der inzwischen entstandene Lösemittelverlust kann in dem Farb­ sammelbecken (17) ersetzt werden. Mit einem bekannten Rührwerk von Hand oder mechanisch können die Lösemittel wieder untergemischt werden, so daß der Lack die erforderliche Viskosität wieder erhält. The fabric broadband ( 1 ) loaded with pure lacquer sludge does not end up in the waste container after the sprinkler water disposal, as provided for in the main patent with coagulated lacquer sludge, but is transported across the entire width by the needle extraction roller ( 6 ) via the flat cover ( 15 ) the solvent container, which serves as a table. On this Flachab cover ( 15 ), a stripper ( 16 ) made of rubber, plastic or other materials is attached in the oblique direction, which strips the pure paint sitting on the fabric broadband ( 1 ) to the side and via a kneader ( 18 ) Ink collection container ( 17 ) feeds. This kneader ( 18 ) separates the adhering water from the paint, so that only pure paint gets into the paint collecting container ( 17 ). The loss of solvent that has occurred in the meantime can be replaced in the paint collecting basin ( 17 ). The solvents can be mixed in again with a known mechanical or mechanical stirrer so that the paint regains the required viscosity.

Über eine Umkehrnadelwalze (19) läuft das Gewebe-Breitband (1) zurück durch einen Lösemittelbehälter (21). Der dem Gewebe- Breitband (1) noch anhaftende restliche Lack wird durch Bürsten­ walzen (20) abgebürstet oder durch Sprühdüsen abgewaschen.The fabric broadband ( 1 ) runs back through a solvent container ( 21 ) via a reversing needle roller ( 19 ). The remaining paint still adhering to the fabric broadband ( 1 ) is brushed by brushing ( 20 ) or washed off by spray nozzles.

Mit dem im Lösemittelbehälter (21) befindlichen Lösemittel, das mit ausgebürsteten Lackresten vermischt ist, kann der Löse­ mittelbedarf im Farb-Sammelbecken (17) ergänzt werden.With the solvent in the solvent container ( 21 ), which is mixed with brushed paint residues, the solvent requirement in the paint collecting basin ( 17 ) can be supplemented.

Das vom Lackschlamm gereinigte Gewebe-Breitband (1) verläßt den Lösemittelbehälter auf der der Anlage zugewandten Breitseite über Wringwalzen (22), um die restlichen Lösemittel- und Farbreste auszupressen. Das Gewebe-Breitband (1) gelangt dann in einen Container (23). Dort kann das Gewebe-Breitband (1) aufgerollt und der Wiederverwendung zugeführt werden.The fabric broadband ( 1 ) cleaned from the paint sludge leaves the solvent tank on the broad side facing the system via wringer rollers ( 22 ) in order to squeeze out the remaining solvent and ink residues. The fabric broadband ( 1 ) then arrives in a container ( 23 ). There the fabric broadband ( 1 ) can be rolled up and reused.

Damit die Vorrichtung und das Verfahren - wie beschrieben - umweltverträglich ist, ist diese Vorrichtung mit einem Gehäuse zu umgeben mit einer Absaugung für Lösemittelgase über die Venti­ lation der Lackieranlage.So that the device and the method - as described - is environmentally compatible, this device is to be surrounded with a housing with a suction for solvent gases via the ventilation of the painting system.
