Abstract

The invention concerns a device for passing the treatment liquor into and out of the treatment space of steam treatment ranges, such as boosters disposed in steamers, and seeks to make it possible to pass the liquor into and out of the treatment by simple and reliable means in a very short time. For this it is proposed according to the invention that the boosters in the steam treatment space of a steamer be connected via liquid lines to receiving vessels which are disposed outside the steam treatment space of the steamer and which are in turn connected to a steam supply line. <IMAGE>

Description

Die Erfindung betrifft eine Einrichtung zur Entnahme und Rückführung der Behandlungsflüssigkeit aus bzw. in im Behandlungsraum von Dampfbehandlungsanlagen, wie Dämpfern angeordneten Flüssigkeitsauftragströgen (Boostern).The invention relates to a device for removing and returning the treatment liquid from or in liquid treatment troughs (boosters) arranged in the treatment room of steam treatment plants, such as steamers.

Bei der Behandlung von textilen Warenbahnen mit Behandlungsflotten hoher Chemikalienkonzentration in Flottenbehältern, durch die eine Flüssigkeit auf die Ware aufgebracht werden soll, besteht die Notwendigkeit, bei eventuellen Warenstillständen die Behandlungsflotte aus den Behältern abzuziehen, um Markierungen auf der Ware durch lange Dauer der Chemikalieneinwirkung zu vermeiden. Die Ab- und Rückführung der Flüssigkeit soll dabei möglichst kurzfristig erfolgen.When treating textile goods webs with treatment liquors with a high chemical concentration in fleet containers, through which a liquid is to be applied to the goods, there is a need to pull the treatment liquor out of the containers in the event of any downtimes in order to avoid markings on the goods due to the long duration of exposure to chemicals . The liquid should be removed and returned as quickly as possible.

Durch die Erfindung soll die Aufgabe gelöst werden, die Ab- und Rückführung der Flüssigkeit aus der bzw.in die Behandlung mit einfachen und betriebssicheren Mitteln in möglichst kurzer Zeit zu ermöglichen.The object of the invention is to enable the removal and return of the liquid from or into the treatment with simple and reliable means in the shortest possible time.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, die Flüssigkeitsauftragströge (Booster) im Dampfbehandlungsraum eines Dämpfers über Flüssigkeitsleitungen mit außerhalb des Dampfbehandlungsraumes des Dämpfers angeordneten Auffangbehältern zu verbinden, die an eine Dampfzuführungsleitung angeschlossen sind.To achieve this object, it is proposed according to the invention to connect the liquid application streams (boosters) in the steam treatment room of a damper via liquid lines to collecting containers which are arranged outside the steam treatment room of the damper and are connected to a steam supply line.

Es hat sich als zweckmäßig erwiesen, die Auffangbehälter für die Behandlungsflüssigkeit mit besonderen Kühleinrichtungen zu versehen.It has proven to be expedient to provide the collecting containers for the treatment liquid with special cooling devices.

In den Flüssigkeitsleitungen für die Zuführung bzw. Abführung der Behandlungsflüssigkeit in bzw.aus den Auffangbehältern, sowie für die Zuführung von Dampf zu den Auffangbehältern sollen über einen Schaltkasten von Hand oder automatisch steuerbare Magnetventile angeordnet sein und vor dem Einlaß der Behandlungsflüssigkeit in den Auffangbehälter soll eine Niveausonde vorgesehen sein.In the liquid lines for the supply or discharge of the treatment liquid in or out of the collecting containers, as well as for the supply of steam to the collecting containers, manually or automatically controllable solenoid valves should be arranged via a switch box and one should be arranged before the treatment liquid is admitted into the collecting container Level probe can be provided.

An Hand der beiliegenden Zeichnung soll die Erfindung nachfolgend noch näher erläutert werden.The invention will be explained in more detail below with the aid of the accompanying drawing.

Zur Kurzzeitspeicherung der Behandlungsflotte (12) aus dem Booster (7) dient der Auffangbehälter (1The collecting container (1.) Is used for short-term storage of the treatment liquor (12) from the booster (7)

Der Behälter wird aus der Dampfleitung (2) über das Druckminderventil(3) mit Dampf von etwa 1 - 1,5 bar gefüllt. Zur erstmal igen Füllung müssen dazu die Magnetventile (4, 5) etwa eine Minute geöffnet werden, um die Luft aus dem Behälter (1) herauszuspülen.The container is filled from the steam line (2) via the pressure reducing valve (3) with steam of about 1 - 1.5 bar. For the first filling, the solenoid valves (4, 5) must be opened for about one minute to flush the air out of the container (1).

Danach werden die Magnetventile (4, 5) geschlossen. Durch Wärmeabgabe über die Behälterwandung kondensiert der Dampf im Behälter (1) und es entsteht ein Vakuum. Die Kondensation kann durch Einbau einer Kühlschlange (6), die von Kühlwasser (11) (z.B. dem Kalten Frischwasser einer Waschmaschine) durchflossen wird, beschleunigt werden.Then the solenoid valves (4, 5) are closed. By emitting heat via the container wall, the steam condenses in the container (1) and a vacuum is created. The condensation can be accelerated by installing a cooling coil (6) through which cooling water (11) (e.g. the cold fresh water of a washing machine) flows.

Soll jetzt die Behandlungsflotte (12) aus dem Booster (7) abgesaugt werden, wird das Magnetventil (8) geöffnet. Durch das Vakuum im Auffangbehälter (1) wird die Flotte (12) in den Behälter (1) gesaugt. Ist die Flotte vollständig aus dem Booster abgesaugt, strömt Dampf an der Niveausonde (9) vorbei, was als Signal zum Schließen des Magnetventils (8) ausgewertet werden kann. Falls erforderlich, kann die Flotte (12) im Behälter (1) mittels Kühlwasser (11) durch die Kühlschlange (6) gekühlt werden. Dadurch kann z.B. ein unerwünschter Chemikalienzerfall verhindert werden.If the treatment liquor (12) is now to be sucked out of the booster (7), the solenoid valve (8) is opened. The liquor (12) is sucked into the container (1) by the vacuum in the collecting container (1). If the liquor is completely sucked out of the booster, steam flows past the level probe (9), which can be evaluated as a signal to close the solenoid valve (8). If necessary, the liquor (12) can be cooled in the container (1) by means of cooling water (11) through the cooling coil (6). This can e.g. an unwanted breakdown of chemicals can be prevented.

Soll vor dem Wiederanlauf der Ware (13) der Booster (7) wieder gefüllt werden, wird durch Knopfdruck am Schaltkasten (10) das Magnetventil (4) geöffnet, wodurch Dampf in den Behälter( 1) einströmt und den Innendruck bis auf den am Druckminderventil (3) eingestellten Druck erhöht. Danach wird das Magnetventil (8) geöffnet und die Flotte (12) durch den Dampfdruck in den Booster gefördert.If the booster (7) is to be filled again before the goods (13) are restarted, the solenoid valve (4) is opened at the push of a button on the control box (10), causing steam to flow into the container (1) and the internal pressure to that on the pressure reducing valve (3) set pressure increased. Then the solenoid valve (8) is opened and the liquor (12) is conveyed into the booster by the steam pressure.

Meldet die Niveausonde (9) Dampf anstatt Flüssigkeit, werden die Ventile (8) und (4) geschlossen.If the level probe (9) reports steam instead of liquid, the valves (8) and (4) are closed.

Nach der Kondensation des Dampfes im Behälter (1) kann die Flotte (12) jederzeit wieder aus dem Booster (7) abgesaugt werden.After the condensation of the steam in the container (1), the liquor (12) can be sucked out of the booster (7) at any time.

Der Auffangbehälter (1) kann unterhalb oder oberhalb des Boosters angeordnet werden.The collecting container (1) can be arranged below or above the booster.

Durch entsprechende elektrische Ansteuerung der Magnetventile (4, 5, 8) kann der Absauge- oder Rückförderungsvorgang nach Einleitung durch Knopfdruck oder externes Signal automatisch gesteuert ablaufen.Appropriate electrical control of the solenoid valves (4, 5, 8) allows the suction or return process to be automatically controlled after initiation by pressing a button or an external signal.

Durch die vorliegende Erfindung wird der Einsatz von Pumpen vermieden, bei denen infolge der heißen Flotte Kavitation auftreten könnte. Außerdem wird der Vorgang des Absaugens und Rückfördern durch die beschriebene Einrichtung sehr vereinfacht.The present invention avoids the use of pumps in which cavitation could occur as a result of the hot liquor. In addition, the process of suction and return is very simplified by the device described.
