There is a rotating washing shaft (20) along the longitudinal axis of the trough, carrying washing tools (14). The tools have a half-open profile, with an aperture facing forwards in the turning direction of the shaft, and forming an angle of less than 90 deg. with the circumference of the trough. There is also an attachment which has washing elements (10) which can be linked to the washing shaft. They may carry similar tools at different angles to the circumference of the trough.

Description

Die Erfindung betrifft eine Waschanlage für Waschgut, insbesondere für mit abschlämmbaren Bestandteilen behafteten Kies, mit einem Trog, durch den Waschgut und Wasser vorzugsweise im Gegenstrom hindurchtreten, mit einer in der Längsachse des Trogs angeordneten, in Drehung angetriebenen Waschwelle und mit Waschwerkzeugen daran, die ein halboffenes Profil mit einer in Drehrichtung der Waschwelle nach vorn weisenden Profilöffnung haben und mit dem Umfang des Trogs in Drehrichtung der Waschwelle einen Keilwinkel von weniger als 90° einschließen.The invention relates to a washing system for laundry, in particular for gravel with drained components, with a trough, through which the laundry and water preferably in countercurrent pass through with one in the longitudinal axis of the trough arranged, rotatingly driven washing shaft and with washing tools remember that the half-open profile with one in the direction of rotation have the profile opening facing the washing shaft and with the circumference of the trough in the direction of rotation of the washing shaft include a wedge angle of less than 90 °.

Eine solche Waschanlage ist aus der EP-A-0 351 607 bekannt. Sie hat tangential an der Waschwelle ansetzende Waschwerkzeuge, die einen kleinen spitzen Keilwinkel mit dem Trogumfang einschließen. Die Waschwerkzeuge üben einen hohen Druck in Umfangsrichtung auf das Waschgut aus, indem letzteres zwischen dem in Drehrichtung vorn halboffenen Profil der Waschwerkzeuge und der Trogwand eingekeilt und zerquetscht wird. Genauer gesagt schamottiert sich der Trog im Betrieb zu, d. h. es bildet sich ein die Trogwand um die Waschwelle und Waschwerkzeuge herum belegender Panzer aus Lehm und/oder Ton und darin eingepreßtem Kies, zwischen dem und den Waschwerkzeugen das Waschgut eingekeilt wird und ein hoher Druckaufbau in Umfangsrichtung erfolgt. Es wird bereits bei niedrigem Füllstand des Trogs ein hoher Druck auf das Waschgut erreicht. Die Waschwerkzeuge bewegen sich mit ziehendem Schnitt durch das Waschgut, dessen abschlämmbare Anteile durch Reibung an den Waschwerkzeugen entlang sehr effektiv aufgelöst und abgeschwemmt werden. Mit dem hohen Druck in Umfangsrichtung geht eine entsprechend starke Reibung und Auflöse- sowie Selbstreinigungswirkung der Waschwerkzeuge einher. Dadurch wird eine sehr gute Waschleistung erreicht.Such a washing system is known from EP-A-0 351 607. It has washing tools attached tangentially to the washing shaft, which enclose a small acute wedge angle with the trough circumference. The washing tools exert high pressure in the circumferential direction on the laundry by placing the latter between the in the direction of rotation front half-open profile of the washing tools and the trough wall is wedged and crushed. More specifically the trough firms up in the company, d. H. it forms a the trough wall around the washing shaft and washing tools covering tank made of clay and / or clay and pressed in Gravel, between which and the washing tools wedged the laundry is and there is a high pressure build-up in the circumferential direction. It becomes high even when the trough is low Pressure on the laundry has been reached. Move the washing tools with a pulling cut through the laundry, its washable Shares due to friction along the washing tools very much effectively dissolved and washed away. With the high pressure in the circumferential direction there is a correspondingly strong friction and Dissolving and self-cleaning effect of the washing tools. This achieves a very good washing performance.

Aufgabe der Erfindung ist es, eine Waschanlage der eingangs genannten Art zu schaffen, die sich durch einen hochgradig modularen Aufbau mit durchweg baugleichen Waschwerkzeugen insbesondere auch für verschiedene Anlagengrößen auszeichnet und eine bauliche Anpassung an die Zusammensetzung des jeweiligen Waschguts und den Reinheitsfortschritt in der Waschanlage ermöglicht, den Verschleiß der Waschwerkzeuge herabsetzt und die Waschleistung optimiert. The object of the invention is to provide a washer at the beginning to create the kind that is characterized by a highly modular Construction with washing tools of identical construction in particular also distinguishes for different plant sizes and one structural adjustment to the composition of the respective laundry and enables cleanliness to progress in the car wash, reduces the wear of the washing tools and the washing performance optimized.

Die diese Aufgabe lösende Waschanlage ist gekennzeichnet durch einen Bausatz wahlweise an der Waschwelle anbringbarer Waschelemente mit baugleichen Waschwerkzeugen, deren Keilwinkel mit dem Trogumfang wenigstens zum Teil verschieden ist.The car wash solving this problem is characterized by a kit of wash elements that can be attached to the wash shaft with identical washing tools, the wedge angle with the trough size is at least partially different.

Waschwerkzeuge, die einen kleinen Keilwinkel mit dem Trogumfang einschließen, haben einen starken Einkeileffekt. Sie bewirken einen hohen Druckaufbau und haben eine starke Quetsch-, Zerreibe- und Auflösewirkung auf das Waschgut. Demgemäß unterliegen Waschwerkzeuge dieser Art einem beträchtlichen Verschleiß, und sie erfordern eine hohe Antriebsleistung der Waschwelle.Washing tools that have a small wedge angle with the trough circumference have a strong wedge effect. They effect a high pressure build-up and have a strong squeezing, grinding and dissolving effect on the laundry. Subject accordingly Washing tools of this type have considerable wear, and they require a high driving power of the washing shaft.

Waschwerkzeuge, die einen größeren Keilwinkel mit dem Trogumfang einschließen, haben einen geringeren Einkeileffekt. Sie sind dementsprechend weniger reinigungswirksam, aber auch nicht so sehr dem Verschleiß unterworfen, und sie erfordern eine geringere Antriebsleistung der Waschwelle.Washing tools that have a larger wedge angle with the trough circumference have a smaller wedge effect. they are accordingly less effective cleaning, but also not so very subject to wear, and they require less Drive power of the washing shaft.

Durch Auswahl von Waschelementen mit Waschwerkzeugen verschiedenen Keilwinkels aus dem erfindungsgemäßen Bausatz lassen sich Waschanlagen einer jeweils gewünschten Waschkapazität an die Zusammensetzung des zu behandelnden Waschguts anpassen und hinsichtlich Standzeit und Leistungsaufnahme optimieren. Auch kann unter eben diesen Optimierungsgesichtspunkten dem Reinheitsfortschritt in der Waschanlage Rechnung getragen werden, indem in Durchtrittsrichtung des Waschguts stromauf Waschwerkzeuge mit kleinem Keilwinkel und in Durchtrittsrichtung des Waschguts stromab Waschwerkzeuge mit größerem Keilwinkel eingesetzt werden. Das anfangs stark verschmutzte Waschgut wird so sehr intensiv und das zunehmend saubere Waschgut nur noch in dem erforderlichen Maß mit den Waschwerkzeugen bearbeitet.By choosing washing elements with washing tools different Wedge angles from the kit according to the invention can be Wash systems of a desired washing capacity to the Adjust the composition of the items to be treated and with regard to Optimize service life and power consumption. Can too from these optimization points of view the progress of purity be taken into account in the car wash by in Direction of passage of the laundry upstream with washing tools small wedge angle and in the direction of passage of the laundry downstream washing tools with a larger wedge angle can be used. The laundry, which is heavily soiled at first, becomes very intense and the increasingly clean laundry only in the required Dimension processed with the washing tools.

Bei einer bevorzugten Ausführungsform der Waschanlage ist die Waschwelle in voneinander axial versetzten Transversalebenen mit jeweils gleichmäßig über ihren Umfang verteilten Waschwerkzeugen bestückt. Die Keilwinkel der Waschwerkzeuge in einer jeden Transversalebene sind vorzugsweise untereinander gleich, wohingegen die Keilwinkel der Waschwerkzeuge von Transversalebene zu Transversalebene wenigstens zum Teil voneinander verschieden sind.In a preferred embodiment of the washer Wash wave in axially offset transverse planes with washing tools evenly distributed over their circumference equipped. The wedge angle of the washing tools in one each transverse plane are preferably identical to one another, whereas the wedge angles of the washing tools from the transverse plane at least partially different from the transverse plane are.

Bei einer bevorzugten Ausführungsform der Waschanlage haben die Waschwerkzeuge ein sich radial nach außen erweiterndes Trapezprofil. Im einzelnen haben die Waschwerkzeuge eine den Keilwinkel mit dem Trogumfang einschließende ebene Rückenplatte rechteckigen Grundrisses und beidseits unter stumpfem Winkel daran ansetzende, axial und radial nach außen sich erstreckende ebene Seitenwände. Die Außenkanten der Seitenwände sind vorzugsweise in Umfangsrichtung gerundet. In a preferred embodiment of the car wash the washing tools have a trapezoidal profile that extends radially outwards. In particular, the washing tools have a wedge angle with a flat back plate enclosing the trough circumference rectangular plan and obtuse on both sides attached to it, axially and radially extending outward flat side walls. The outer edges of the side walls are preferred rounded in the circumferential direction.

Bei einer bevorzugten Ausführungsform der Waschanlage ist ein jedes Waschwerkzeug im Bereich der der Profilöffnung abgewandten Rückseite seiner Rückenplatte an einer vorzugsweise mittigen, in Profillängsrichtung sich erstreckenden Tragplatte angebracht, die dem Keilwinkel des Waschwerkzeugs entsprechend abgeschrägt ist. Verschiedene Keilwinkel baugleicher Waschwerkzeuge werden so sehr einfach durch verschiedene Winkelschrägen der jeweiligen Tragplatten realisiert.In a preferred embodiment of the washing system is a each washing tool in the area facing away from the profile opening Back of his back plate on a preferably central, attached support plate extending in the longitudinal direction of the profile, which beveled according to the wedge angle of the washing tool is. Different wedge angles of identical washing tools are available so very simply by different angles of the respective Carrier plates realized.

Es empfiehlt sich eine lösbare, nach Verschleiß auswechselbare Anbringung des Waschwerkzeugs an der Tragplatte. Vorzugsweise trägt die Tragplatte eine Zwischenplatte, auf der das Waschwerkzeug mit seiner Rückenplatte aufsitzt und verschraubt ist.A detachable, replaceable after wear is recommended Attachment of the washing tool to the support plate. Preferably the support plate carries an intermediate plate on which the washing tool is seated with its back plate and screwed.

Bei einer bevorzugten Ausführungsform der Waschanlage trägt die Tragplatte überdies eine dem Waschwerkzeug radial innen vorgeordnete Verschleißschutzplatte, die vorzugsweise rechteckig ist und weiter vorzugsweise in ihrer Breite der der Rückenplatte des Waschwerkzeugs entspricht. Die Verschleißschutzplatte dient dazu, die Tragplatte vor Verschleiß zu bewahren. Sie übt überdies eine Umrührwirkung auf das Waschgut aus.In a preferred embodiment the washer carries the support plate also a radially inside the washing tool upstream wear protection plate, which is preferably rectangular is and more preferably in width that of the back plate of the washing tool. The wear protection plate serves to protect the support plate from wear. She also practices a stirring effect on the laundry.

Eine Tragplatte kann gleichermaßen mit einem oder mehreren Waschwerkzeugen und gegebenenfalls einer oder mehreren Verschleißschutzplatten bestückt sein. A support plate can be used with one or more Washing tools and possibly one or more wear protection plates be equipped.

Bei einer bevorzugten Ausführungsform wird die Tragplatte an einer mit der Waschwelle fest verbundenen, vorzugsweise damit verschweißten Montageplatte festgeschraubt. Zu diesem Zweck sind bei der EP-A 0 351 607 Paare axial beabstandeter Montageplatten vorgesehen, die beide mit der Waschwelle verschweißt sind. Eine Tragplatte mit einem Waschwerkzeug daran wird zwischen den Montageplatten eingesteckt und mit den Montageplatten durchverschraubt. Das erfordert eine sehr genaue Passung, da es bei nicht vorhandener Flächenpressung zu einem Ausschlagen der Schraubverbindung, einer Langlochbildung und einem Abscheren der Schraube kommen kann. Erfindungsgemäß bevorzugt ist daher, die Tragplatte zwischen einer mit der Waschwelle verschweißten Montageplatte und einem lose auf der Waschwelle aufsitzenden Montagering einzuspannen. Letzterer kann dünner als die Montageplatte sein.In a preferred embodiment, the support plate is on one firmly connected to the washing shaft, preferably with it welded mounting plate screwed tight. To this end are pairs of axially spaced mounting plates in EP-A 0 351 607 provided, both welded to the washing shaft are. A support plate with a washing tool on it is between the mounting plates and with the mounting plates screwed through. That requires a very precise fit, because if the surface pressure does not exist, it will deflect the screw connection, an elongated hole and shearing the screw can come. It is therefore preferred according to the invention the support plate between a welded to the washing shaft Mounting plate and a loose one sitting on the washing shaft Clamp the mounting ring. The latter can be thinner than the mounting plate his.

Bei einer bevorzugten Ausführungsform der Waschanlage ist die Montageplatte außen regelmäßig polygonal. Die Tragplatte stützt sich an einer Polygonseite der Montageplatte formschlüssig ab. Dadurch wird mit geringem Bauaufwand eine stabile Drehmomentabstützung der Waschwerkzeuge erreicht. Montageplatte und Montagering können aber sehr wohl auch rund sein und die Drehmomentabstützung in anderer geeigneter Weise bewirkt werden.In a preferred embodiment of the washer Mounting plate on the outside regularly polygonal. The support plate supports form-fitting on a polygon side of the mounting plate. This results in stable torque support with little construction effort of the washing tools. Mounting plate and mounting ring can also be round and the torque support can be effected in another suitable manner.
