Abstract

An immersion plant has a lifting device (5) operating a lifting table (7) for the workpieces, which moves up and down during cleaning. There is a baffle plate (10) under the lifting table, which during treatment, is moved up and down in a sector of the immersion bath with little side play, so that the cleaning fluid is expelled during the down stroke, creating turbulence which acts on the workpieces.

Description

Die Erfindung betrifft eine Hub-Tauchanlage zum Behandeln, insbesondere zum Reinigen von Werkstücken, mit einem Gehäuse, in das eine Behandlungsflüssigkeit, insbesondere eine Reinigungsflüssigkeit einfüllbar ist, die im unteren Bereich des Gehäuses ein Tauchbad bildet, ferner mit einer Hubeinrichtung und einem damit verbundenen, mit Durchgangsöffnungen versehenen Hubtisch, auf den die Werkstücke aufbringbar sind und der beim Behandlungsvorgang aufwärts und abwärts in dem Tauchbad bewegbar ist.The invention relates to a lifting dip system for treating, in particular for cleaning workpieces, with a housing into which a treatment liquid, in particular a cleaning liquid can be introduced, which forms an immersion bath in the lower region of the housing, further comprising a lifting device and an associated provided with through openings lifting table on which the workpieces are applied and which is movable in the treatment process upwards and downwards in the dipping bath.

Mit einer solchen Anlage können Werkstücke nicht nur gereinigt und entfettet, sondern beispielsweise auch entlackt, konserviert und phosphatiert werden, wozu die jeweils geeignete Behandlungsflüssigkeit verwendet wird.With such a plant workpieces can not only be cleaned and degreased, but also, for example, stripped, preserved and phosphated, using the appropriate treatment liquid is used.

Die zu behandelnden Werkstücke werden dabei zunächst auf den in dem Gehäuse angeordneten Hubtisch gelegt, der nach dem Schließen des Deckels des Gehäuses abgesenkt wird, woraufhin der Behandlungsvorgang beginnt. Dabei wird der Hubtisch in dem Tauchbad, das sich in dem Gehäuse befindet, stetig aufwärts und abwärts bewegt, wodurch eine Flüssigkeitsbewegung erzeugt wird, durch die die Werkstücke allseits abgereinigt werden.The workpieces to be treated are first placed on the arranged in the housing lifting table, which is lowered after closing the lid of the housing, whereupon the treatment process begins. In this case, the lifting table in the immersion bath, which is located in the housing, steadily moved up and down, whereby a liquid movement is generated, by which the workpieces are cleaned on all sides.

Die bisher bekannten Anlagen dieser Art haben einen aufwändigen Aufbau und benötigen eine lange Behandlungszeit, um eine zufriedenstellende Reinigungswirkung zu erzielen.The previously known systems of this type have a complex structure and require a long treatment time to achieve a satisfactory cleaning effect.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Hub-Tauchanlage der betrachteten Art anzugeben, die mit einem einfachen Aufbau eine erheblich verbesserte Behandlungswirkung erzielt.The present invention has for its object to provide a hub diving system of the type considered, which achieves a significantly improved treatment effect with a simple structure.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are characterized in the subclaims.

Die Erfindung sieht vor, daß unter dem Hubtisch ein Schwallblech befestigt ist, das beim Behandlungsvorgang in einem wannenförmigen Bodenabschnitt des Tauchbads mit geringem seitlichen Spiel zu dessen Wänden aufwärts und abwärts bewegt wird, so daß Behandlungsflüssigkeit bei der Abwärtsbewegung verdrängt wird und mit hohem Druck durch das Tauchbad in Richtung des Hubtischs und die darauf angeordneten Werkstücke gerichtet wird. Dabei erzeugt die unter dem Schwallblech verdrängte und zum Hubtisch gerichtete Flüssigkeit starke Turbulenzen in dem Tauchbad, so daß die Wirkung des Tauchbads auf die Gegenstände stark erhöht wird. Bei etwa 60 Hüben/min und einer Hubstrecke von vorzugsweise 50 bis 100 mm erhöht sich die Wirkung durch diese Turbulenzen um etwa 100%.The invention provides that under the lifting table, a baffle plate is attached, which is moved during the treatment process in a trough-shaped bottom portion of the dipping with little lateral play upwards and downwards to the walls, so that treatment liquid is displaced during the downward movement and high pressure through the Dipping is directed in the direction of the lifting table and the workpieces arranged thereon. In this case, the liquid displaced under the baffle plate and directed towards the lifting table produces strong turbulence in the dipping bath, so that the effect of the dipping bath on the objects is greatly increased. At about 60 strokes / min and a stroke distance of preferably 50 to 100 mm, the effect of these turbulences increases by about 100%.

Der Bodenabschnitt des Tauchbads ist bevorzugt durch eine Vertiefung am Boden des Gehäuses ausgebildet, wobei zwischen den Wänden dieser Vertiefung und dem Rand des Schwallblechs ein umlaufender Spalt verbleibt.The bottom portion of the immersion bath is preferably formed by a depression at the bottom of the housing, wherein between the walls of this recess and the edge of the baffle plate, a circumferential gap remains.

Die durch die Abwärtsbewegung des Hubtischs und damit des Schwallblechs verdrängte Flüssigkeit kann auf verschiedene Arten und in verschiedenen Richtungen auf die Werkstücke gerichtet werden, die entweder einzeln oder kombiniert miteinander vorgesehen sein können. Nach einem ersten Aspekt der Erfindung enthält das Schwallblech Durchgangsöffnungen für die Behandlungsflüssigkeit, die die Form schmaler Schlitze und/oder Löcher haben können. Wenn das Schwallblech in der wannenförmigen Vertiefung nach unten gedrückt wird, treten durch die Öffnungen des Schwallblechs kräftige Flüssigkeitsstrahlen nach oben aus, die durch den bevorzugt gitterartigen Hubtisch hindurch Turbulenzen erzeugen und mit kräftigen Strömungen auf die Gegenstände auftreffen, die damit wirkungsvoll gereinigt oder anderweitig von der Flüssigkeit behandelt werden. Bei der anschließenden Aufwärtsbewegung des Hubtischs und des Schwallblechs fließt Behandlungsflüssigkeit wieder unter das Schwallblech zurück. Hierzu sind bevorzugt Ventilklappen an dem Schwallblech vorgesehen, die bei der Abwärtsbewegung geschlossen sind und sich bei der Aufwärtsbewegung öffnen.The displaced by the downward movement of the lifting table and thus the baffle liquid can be directed in various ways and in different directions on the workpieces, which can be provided either individually or in combination with each other. According to a first aspect of the invention, the baffle contains passageways for the treatment liquid, which may be in the form of narrow slits and / or holes. If the baffle in the trough-shaped depression down is pressed, pass through the openings of the baffle strong liquid jets upwards, which generate turbulence through the preferred grid-like lifting table and impinge with strong currents on the objects, which are thus effectively cleaned or otherwise treated by the liquid. During the subsequent upward movement of the lifting table and the baffle, treatment liquid flows back under the baffle plate. For this purpose, valve flaps are preferably provided on the baffle plate, which are closed during the downward movement and open during the upward movement.

Es versteht sich, daß das Schwallblech eine ausreichende Steifigkeit haben muß, um die Behandlungsflüssigkeit wirkungsvoll verdrängen zu können. Dabei kann vorgesehen sein, daß das Schwallblech an den Randkanten in einem flachen Winkel abgebogen ist, um dem Flüssigkeitsdruck besser standhalten zu können.It is understood that the baffle plate must have sufficient rigidity in order to effectively displace the treatment liquid can. It can be provided that the baffle plate is bent at the marginal edges at a shallow angle in order to better withstand the fluid pressure can.

Nach einem weiteren Aspekt der Erfindung wird vorgeschlagen, daß mit der wannenförmigen Vertiefung im unteren Teil des Tauchbads ein aufrechter, vorzugsweise vertikaler Strömungskanal in Verbindung steht, der sich bis über die obere Position des Hubtischs (beim Behandlungsvorgang) erstreckt, und der seitliche Austrittsöffnungen hat, aus denen Flüssigkeit, die aus der Vertiefung in den Strömungskanal verdrängt wurde, durch das Tauchbad in Richtung der Werkstücke gerichtet wird. Diese Wasserstrahlen erzeugen demnach von der Seite und von oben auf die Werkstücke einwirkende Strömungen und Turbulenzen, die ebenfalls zu einer hochgradigen Reinigungswirkung beitragen.According to a further aspect of the invention it is proposed that with the trough-shaped depression in the lower part of the dip an upright, preferably vertical flow channel is in communication, which extends to above the upper position of the lifting table (during the treatment process), and has lateral outlet openings, from which liquid, which has been displaced from the depression in the flow channel, is directed by the dipping bath in the direction of the workpieces. These jets of water thus produce flows and turbulence acting on the workpieces from the side and from above, which also contribute to a high degree of cleaning action.

Bei dieser Ausgestaltung der Erfindung kann das Schwallblech die oben erwähnten Durchgangsöffnungen haben, die insgesamt kleiner zu bemessen sind, so daß außerdem eine ausreichende Behandlungsflüssigkeitsmenge in den Strömungskanal verdrängt wird, so daß sowohl von unten als auch von der Seite und/oder oben kräftige Wasserstrahlen auf den Hubtisch gerichtet werden. Es kann aber auch vorgesehen sein, daß das Schwallblech eine geschlossene Fläche hat, so daß die Wasserstrahlen bei der Abwärtsbewegung des Hubtischs nur aus dem seitlichen Strömungskanal austreten.In this embodiment of the invention, the baffle may have the above-mentioned through holes, which are to be smaller overall, so that also a sufficient amount of treatment liquid is displaced in the flow channel, so that both from below and from the side and / or above strong water jets on be directed to the lift table. But it can also be provided that the baffle plate a closed area has, so that the water jets emerge during the downward movement of the lifting table only from the lateral flow channel.

In der Seitenwand des Strömungskanals sind zum Austritt der Flüssigkeit Durchgangsöffnungen vorgesehen, die auch hier die Form schmaler Schlitze und/oder von Löchern haben können.In the side wall of the flow channel through openings are provided for the exit of the liquid, which may also have the form of narrow slits and / or holes here.

Es liegt im Rahmen der Erfindung, daß zwei getrennte Strömungskanäle vorgesehen sein können, die sich - zusammengenommen - im wesentlichen über die gesamte Breite des Gehäuses erstrecken, so daß alle auf dem Hubtisch angeordneten Gegenstände von den durch die austretenden Flüssigkeitsstrahlen erzeugten Turbulenzen erfaßt werden können.It is within the scope of the invention that two separate flow channels can be provided, which - taken together - extend substantially over the entire width of the housing, so that all arranged on the lifting table objects can be detected by the turbulence generated by the exiting liquid jets.

Nach einem weiteren Vorschlag der Erfindung ist vorgesehen, daß die Hubeinrichtung des Hubtischs durch einen einzigen Hubzylinder gebildet ist, der in einer bevorzugten Ausführungsform ein Pneumatikzylinder ist. Der Hubzylinder ist vorteilhafterweise nahe der Rückwand des Gehäuses in deren Mitte angeordnet und antriebsmäßig mit einer Gleitführung verbunden, an der der Hubtisch befestigt ist. An der Rückwand des Gehäuses ist dessen aufklappbarer Deckel angelenkt.According to a further proposal of the invention it is provided that the lifting device of the lifting table is formed by a single lifting cylinder, which is a pneumatic cylinder in a preferred embodiment. The lifting cylinder is advantageously disposed near the rear wall of the housing in the center thereof and drivingly connected to a sliding guide on which the lifting table is mounted. On the rear wall of the housing whose hinged lid is hinged.

Mit großem Vorteil ist vorgesehen, daß der Deckel durch den Hubzylinder geöffnet wird, wenn der Hubtisch zur Entnahme der behandelten Werkstücke ganz nach oben gefahren wird. Dabei trifft die mit dem Hubzylinder verbundene Gleitführung auf den Deckel auf und schwenkt diesen in die Öffnungsstellung. Damit kommt die gesamte Anlage mit nur einem einzigen Zylinder aus, wodurch sie einen besonders einfachen Aufbau erhält. Die Hubbewegung nach unten bewirkt dabei gleichzeitig das Schließen des schwenkbaren Deckels, durch Schwerkraft.With great advantage, it is provided that the lid is opened by the lifting cylinder when the lifting table is moved to remove the treated workpieces all the way up. The sliding guide connected to the lifting cylinder impinges on the cover and pivots it into the open position. Thus, the entire system comes out with only a single cylinder, giving it a particularly simple structure. The lifting movement downwards simultaneously causes the closing of the hinged lid, by gravity.

Da bei dieser Ausführungsform kein elektrischer Anschluß erforderlich ist, ist die Anlage auch für den Einsatz von brennbaren und explosionsgefährdeten Behandlungsflüssigkeiten wie Waschbenzin bestens geeignet.Since no electrical connection is required in this embodiment, the system is also ideally suited for the use of flammable and potentially explosive treatment liquids such as benzene.

Dabei liegt es aber im Rahmen der Erfindung, daß als Behandlungsflüssigkeit z.B. auch wäßrige Laugen einsetzbar sind, die z.B. über elektrische Heizpatronen beheizt werden können.However, it is within the scope of the invention that as treatment liquid, e.g. it is also possible to use aqueous alkalis which are e.g. can be heated by electric heating cartridges.

Nach einem weiteren Vorschlag der Erfindung enthält die Anlage außerdem eine Einrichtung zum Abführen von an der Oberfläche des Behandlungsbades abgesetzten Ölen, Fetten und Schmutzpartikeln. Hierzu kann ein Düsensystem in dem Behälter angeordnet sein, das eine Oberflächenbewegung hervorruft, wodurch die aufschwimmenden Öle und Fette in ein seitlich angeflanschtes Beruhigungsbecken abgeleitet werden. Eine Trennung des Öl-Wasser-Gemischs kann über eine geeignete Ölabscheideeinrichtung erfolgen.According to a further proposal of the invention, the plant also contains a device for removing oils, fats and dirt particles deposited on the surface of the treatment bath. For this purpose, a nozzle system can be arranged in the container, which causes a surface movement, whereby the floating oils and fats are discharged into a laterally flanged calming basin. A separation of the oil-water mixture can take place via a suitable Ölabscheideeinrichtung.

Bei dieser Ausgestaltung der Erfindung verbleiben die Werkstücke nach dem Behandlungsvorgang noch so lange im Tauchbad auf dem Hubtisch, bis die an der Flüssigkeitsoberfläche abgesetzten Öle etc. abgeführt sind, woraufhin der Hubtisch in die Lade- und Entladeebene angehoben wird.In this embodiment of the invention, the workpieces still remain after the treatment process in the immersion bath on the lift table until the settled on the liquid surface oils, etc. are removed, whereupon the lift table is raised in the loading and unloading.

In der Mitte der Rückwand 4 ist in dem Behälter ein vertikal ausgerichteter Pneumatik-Hubzylinder 5 angebracht, der von einer Gleitführung 6 für einen Hubtisch 7 umgeben ist. Die Kolbenstange 8 des Hubzylinders 5 steht mit dem mit dem Hubtisch 7 verbundenen Element der Gleitführung 6 in Antriebsverbindung, so daß der Hubtisch 7 durch die pneumatische Kolben/Zylinderanordnung 5 heb- und senkbar ist.FIGS. 1A to 1G show a first embodiment of the lifting immersion system according to the invention. A container 1, which stands on feet 2, is provided with a hinged lid 3, which is hinged to the rear wall of the container 1. In the middle of the rear wall 4, a vertically oriented pneumatic lifting cylinder 5 is mounted in the container, which is surrounded by a sliding guide 6 for a lifting table 7. The piston rod 8 of the lifting cylinder 5 is connected to the connected to the lifting table 7 element of the sliding guide 6 in drive connection, so that the lifting table 7 can be raised and lowered by the pneumatic piston / cylinder assembly 5.

Der Hubtisch 7 enthält eine gitterartige Auflagefläche für die zu behandelnden Gegenstände.The lifting table 7 contains a grid-like support surface for the objects to be treated.

Am Boden des Behälters 1 ist eine wannenförmige Vertiefung 9 ausgebildet in die ein Schwallblech 10 mit geringem seitlichen Spiel eintreten kann, wobei das Schwallblech durch Stege 11 unter dem Hubtisch, im Abstand zu diesem, befestigt ist. Neben der Bodenvertiefung 9 ist eine Schmutzsammelrinne 12 ausgebildet, die mit einem Ablaßhahn 13 versehen ist, mit dem angesammelter Schmutz aus dem Gehäuse 1 abführbar ist.At the bottom of the container 1, a trough-shaped recess 9 is formed into which a baffle plate 10 can enter with little lateral clearance, wherein the baffle plate is secured by webs 11 under the lifting table, at a distance therefrom. In addition to the bottom recess 9 a dirt collecting channel 12 is formed, which is provided with a drain cock 13, with the accumulated dirt from the housing 1 can be discharged.

Das Schwallblech 10 ist bei dieser Ausführungsform mit einer Vielzahl von in Längsrichtung des Gerätes gleichmäßig beabstandeten, schmalen Schlitzen 14 versehen, deren Zweck weiter unten beschrieben wird.The baffle 10 is provided in this embodiment with a plurality of evenly spaced in the longitudinal direction of the device, narrow slots 14, the purpose of which will be described below.

Figur 1 D zeigt die Lade- und Endladeposition des Hubtischs 7. In dieser Position ist die Kolbenstange 8 der pneumatischen Kolben/Zylinderanordnung 5 vollständig ausgefahren, wobei das an dem Hubtisch 7 befestigte Gleitführungselement den Hubtisch in die oberste Lage innerhalb des Gehäuses 1 angehoben hat. Dabei ist das Gleitführungselement mit der Kolbenstange 8 auf den zuvor geschlossenen Deckel 3 aufgelaufen und hat diesen in die in Figur 1 D dargestellte Öffnungsstellung geschwenkt.FIG. 1 D shows the loading and unloading position of the lifting table 7. In this position, the piston rod 8 of the pneumatic piston / cylinder arrangement 5 is fully extended, wherein the sliding guide element fastened to the lifting table 7 moves the lifting table into the uppermost position within the housing 1 has raised. In this case, the sliding guide has accumulated with the piston rod 8 on the previously closed lid 3 and has pivoted it into the open position shown in Figure 1 D.

Nachdem beispielsweise zu reinigende Gegenstände auf den Hubtisch 7 aufgebracht bzw. in dessen gitterförmigen Korb eingelegt worden sind, wird der Hubtisch nach unten verfahren, wobei sich der Deckel infolge Schwerkraft in die Verschlußstellung bewegt. In dem Behälter befindet sich ein Behandlungsbad, bei dem es sich im Falle eines Reinigungsvorgangs um eine Lauge oder beispielsweise Waschbenzin handeln kann.For example, after objects to be cleaned have been applied to the lifting table 7 or placed in its grid-shaped basket, the lifting table is moved downwards, with the lid moving into the closed position as a result of gravity. In the container there is a treatment bath which, in the case of a cleaning process, may be an alkali or, for example, mineral spirits.

Der Hubtisch 7 wird nach sicherem Verschluß des Deckels zunächst in die in den Figuren 1C und 1 F dargestellte obere Position des Behandlungsvorgangs abgesenkt, in der sich das Schwallblech 10 in einem kleinen Abstand über dem Rand der Vertiefung 9 am Boden des Gehäuses befindet. Aus der schematischen Darstellung der Figur 1 F ist zu sehen, daß das Schwallblech an zwei gegenüberliegenden Rändern im flachen Winkel nach unten abgebogen ist.The lifting table 7 is lowered after secure closure of the lid first in the illustrated in Figures 1C and 1 F upper position of the treatment process in which the baffle plate 10 is located at a small distance above the edge of the recess 9 at the bottom of the housing. From the schematic representation of Figure 1 F can be seen that the baffle plate is bent at two opposite edges at a shallow angle downwards.

Beim Behandlungsvorgang, d.h. beispielsweise beim Reinigungsvorgang des Gerätes, wird der Hubtisch 7 in dem Tauchbad mit einer Frequenz von vorzugsweise 40 bis 80 Hüben/Minute, am meisten bevorzugt von 60 Hüben/Minute zwischen den in den Figuren 1F/1C und 1B/1E gezeigten Positionen aufwärts und abwärts bewegt, wobei jeweils ein Hubweg von vorzugsweise 50 bis 100 mm zurückgelegt wird. Wenn das Schwallblech auf seinem Weg nach unten mit geringem seitlichen Spiel in die Vertiefung 9 eintaucht, wird Behandlungsflüssigkeit durch die Schlitze 14 nach oben verdrängt, wobei die Flüssigkeitsstrahlen kräftige Turbulenzen in dem Tauchbad hervorrufen, die die durch die Aufwärts- und Abwärtsbewegung hervorgerufene Behandlungswirkung erheblich verstärken. Der Wirkungsgrad der Anlage läßt sich durch die durch die verdrängte Flüssigkeit erzeugten Turbulenzen ohne weiteres verdoppeln.During the treatment process, ie for example during the cleaning process of the apparatus, the lifting table 7 is immersed in the immersion bath at a frequency of preferably 40 to 80 strokes / minute, most preferably 60 strokes / minute between those shown in Figures 1F / 1C and 1B / 1E Moves positions up and down, each with a stroke of preferably 50 to 100 mm covered. When the baffle is immersed in the depression 9 on its way down with little lateral play, treatment liquid is displaced upwards through the slits 14, the liquid jets causing strong turbulence in the dipping bath which greatly enhance the treatment effect caused by the upward and downward movement , The efficiency of the system can easily be doubled by the turbulence generated by the displaced liquid.

In der oberen Position des Behandlungsvorgangs befindet sich das Schwallblech 10 im Abstand über dem Rand der Vertiefung 9, so daß zuvor verdrängte Flüssigkeit wieder unter das Schwallblech 10 zurückfließen kann.In the upper position of the treatment process, the baffle plate 10 is at a distance above the edge of the recess 9, so that previously displaced liquid can flow back under the baffle plate 10 again.

Die in den Figuren 2A bis 2G dargestellte zweite Ausführungsform der Erfindung unterscheidet sich von der ersten Ausführungsform dadurch, daß die Schmutzsammelrinne 12 an der dem Hubzylinder 5 zugewandten Seite des Schwallblechs 10 angeordnet ist. Auch hier ist die Schmutzsammelrinne mit einem aus dem Gehäuse 1 herausführenden Ablaßhahn 13 versehen. Außerdem sind Puffer 15 außerhalb der Bewegungsbahn des Schwallblechs 10 vorgesehen, auf die der Hubtisch 7 in der unteren Position auftrifft. Ansonsten stimmt die zweite Ausführungsform der Erfindung mit der ersten Ausführungsform überein.The illustrated in Figures 2A to 2G second embodiment of the invention differs from the first embodiment in that the dirt collecting channel 12 is arranged on the lifting cylinder 5 facing side of the baffle plate 10. Again, the dirt collecting channel is provided with a leading out of the housing 1 drain cock 13. In addition, buffers 15 are provided outside the movement path of the baffle 10, which is incident on the lifting table 7 in the lower position. Otherwise, the second embodiment of the invention is consistent with the first embodiment.

Die in den Figuren 3A bis 3G dargestellte dritte Ausführungsform der Erfindung enthält einige wesentliche Änderungen. Bei dieser Ausführungsform ist das Schwallblech 17 ein geschlossenes Blech ohne Durchtrittsöffnung für verdrängte Flüssigkeit. Die Bodenvertiefung 9, in die das Schwallblech 17 beim Behandlungsvorgang eintritt, steht mit einem vertikal sich nach oben sich erstreckenden Strömungskanal 18 in Verbindung, der sich bis über die obere Position des Hubtischs 7 hinaus (beim Behandlungsvorgang) erstreckt. Der Strömungskanal 18 hat in der dem Hubtisch 7 zugewandten Wand wenigstens einen, bevorzugt mehrere Austrittsschlitze, von denen in den schematischen Darstellungen der Figuren 3B bis 3G nur ein am oberen Rand angeordneter Austrittschlitz 19 dargestellt ist. Weitere Schlitze können sich darunter befinden, was aber nicht unbedingt der Fall sein muß.The third embodiment of the invention illustrated in FIGS. 3A to 3G contains some significant changes. In this embodiment, the baffle plate 17 is a closed plate without passage for displaced liquid. The bottom depression 9, into which the baffle plate 17 enters during the treatment process, communicates with a vertically upwardly extending flow channel 18, which extends beyond the upper position of the lifting table 7 (during the treatment process). The flow channel 18 has in the lifting table 7 facing wall at least one, preferably a plurality of outlet slots, of which in the schematic representations of Figures 3B to 3G only one arranged at the top edge exit slot 19 is shown. Other slots may be underneath, but this is not necessarily the case.

Wie die Figuren 3E bis 3G zeigen, kann der Strömungskanal 19 auch aus zwei getrennten Strömungskanälen beidseitig der Gleitführung 6 bestehen.As FIGS. 3E to 3G show, the flow channel 19 can also consist of two separate flow channels on both sides of the sliding guide 6.

Bei dieser Ausführungsform wird bei der Abwärtsbewegung des Hubtischs 7 und des daran befestigten Schwallblechs 17 Flüssigkeit aus der Vertiefung 9 in den Strömungskanal 18 verdrängt, in dem (bzw. in denen) die Behandlungsflüssigkeit nach oben gedrückt wird und aus dem Schlitz 19 (und gegebenenfalls weiteren Schlitzen) in Richtung des Hubtischs 7 austritt. Dabei erzeugen die ausgestoßenen Wasserstrahlen kräftige Turbulenzen in dem Tauchbad, die wiederum die Behandlungswirkung erheblich verstärken.In this embodiment, during the downward movement of the lifting table 7 and the baffle 17 attached thereto, liquid is displaced from the depression 9 into the flow channel 18, in which (or in which) the treatment liquid is pushed upward and out of the slot 19 (and optionally further slots) in the direction of the lifting table 7 emerges. The ejected water jets generate strong turbulence in the dip, which in turn significantly enhance the treatment effect.

Es versteht sich, daß es im Rahmen der Erfindung liegt, daß bei der dritten Ausführungsform auch Schlitze oder Löcher in dem Schwallblech vorgesehen sein können, so daß sowohl von dem Schwallblech aus als auch von dem Strömungskanal aus Turbulenzen in dem Tauchbad erzeugt werden.It is understood that it is within the scope of the invention that in the third embodiment, slots or holes may be provided in the baffle plate, so that turbulence in both the baffle and from the flow channel are generated in the dip.

Die Figuren 4A bis 4G zeigen eine vierte Ausführungsform, die der dritten Ausführungsform ähnelt. Es sind Ventilklappen 20 vorgesehen, die aus ebenen Platten bestehen, die verschieblich auf kurzen Stiften 21 unter dem Schwallblech 10 befestigt sind. Im Bereich der Ventilklappen 20 befinden sich große Durchtrittsöffnungen in dem Schwallblech 10, die von den Ventilklappen 20 überdeckt werden.Figures 4A to 4G show a fourth embodiment, which is similar to the third embodiment. There are valve flaps 20 are provided, which consist of flat plates which are slidably mounted on short pins 21 under the baffle plate 10. In the region of the valve flaps 20 are large passage openings in the baffle plate 10, which are covered by the valve flaps 20.

Bei der Abwärtsbewegung des Schwallblechs in die Vertiefung 9 bewirkt der Gegendruck der Flüssigkeit, daß sich die Ventilklappen 20 dicht an die Unterseite des Schwallblechs 10 anlegen, womit die Durchgangsöffnungen 22 in dem Schwallblech geschlossen sind. Auf diese Weise kann Flüssigkeit aus der Vertiefung 9 entweder durch Schlitze des Schwallblechs (wie bei den ersten beiden Ausführungsformen) und/oder zwischen den Rändern des Schwallblechs und den Wänden der Vertiefung und des Gehäuses, die damit Strömungskanäle bilden, unter hohem Druck nach oben verdrängt werden.During the downward movement of the baffle plate in the recess 9 causes the back pressure of the liquid that the valve flaps 20 create tightly against the underside of the baffle plate 10, whereby the passage openings 22 are closed in the baffle plate. In this way, liquid may be displaced upwardly from the well 9 either through slots of the baffle (as in the first two embodiments) and / or between the edges of the baffle and the walls of the well and housing forming flow passages become.

Wenn der Hubtisch aufwärts bewegt wird, gleiten die Ventilklappen an den Stiften eine kleine Strecke weg von dem Schwallblech, bis sie beispielsweise an Köpfen der Stifte anliegen, so daß bei der Aufwärtsbewegung des Schwallblechs Behandlungsflüssigkeit durch die Öffnungen 22 unter das Schwallblech hindurchtreten kann.As the lift table is moved upwardly, the valve flaps slide against the pins a small distance away from the baffle until they abut, for example, heads of the pins, so that upon the upward movement of the baffle, treatment liquid can pass through the openings 22 below the baffle.

Das Schwallblech 10 bildet wie oben erwähnt, mit den Wänden der Vertiefung und des Gehäuses Strömungskanäle.The baffle 10 forms, as mentioned above, with the walls of the recess and the housing flow channels.

Die Hub-Tauchanlage hat eine Einrichtung zum Abführen von an der Oberfläche des Behandlungsbades abgesetzten Ölen, Fetten und Schmutzpartikeln. In dieser Abführeinrichtung ist ein Düsensystem in dem Behälter 1 vorgesehen, das eine Oberflächenbewegung der Behandlungsflüssigkeit erzeugt.The lift dipping unit has a device for discharging oils, fats and dirt particles deposited on the surface of the treatment bath. In this discharge device, a nozzle system is provided in the container 1, which generates a surface movement of the treatment liquid.

Es wird betont, dass die beschriebenen und dargestellten Ausführungsformen als die Erfindung nicht beschränkende Beispiele anzusehen sind. Die einzelnen Merkmale der Ausführungsformen sind auf jede Weise miteinander kombinierbar.It is emphasized that the embodiments described and illustrated are to be regarded as non-limiting examples of the invention. The individual features of the embodiments can be combined with each other in any way.
