Description

in Durlach, Badenin Durlach, Baden

Es ist bei Naßputzanlagen üblich, den aus dem Putzraum kommenden Sand zusammen mit dem Putzwasser in einer Grube aufzu- >fangen und aus dieser das Wasser abzuschlämmen oder abzufiltern, so daß nur der Sand und die Formeisen in der Grube bleiben, die dann von Hand oder mechanisch von dort entfernt werden. Bei dieser Einrichtung machten sich folgende Mängel bemerkbar. ίο Zwecks Entfernung des Sandes aus der Grube ist es erforderlich, die Putzanlage außer Betrieb zu setzen, und zwar 'so lange, bis das Wasser gut abgefiltert ist. Bei der Entfernung des Sandes ist mit Vorsicht zu verfähren, um die Kern- und Formeisen, die zwischen dem Sand liegen, zurückzugewinnen und sie nicht zu zerstören, und schließlich auch, um nicht 'Metallstücke in dem wieder zu verwendenden Sand zu haben. Da die Putzanlage in dem Xjebäude der Putzerei unterzubringen ist, entsteht bei Neuanlagen, stets die Schwierigkeit der Anlage mehrerer Senkgruben hintereinander. In dieser Beziehung ist auch das Herausnehmen des Sandes aus der Grube sehr lästig und störend. Bei starker Kälte friert die Grube leicht während der Napht ein, und der Betrieb ist am nächsten Morgen gehemmt.It is common in wet plastering systems to collect the sand coming from the cleaning room to collect with the cleaning water in a pit and to remove the water from it or to filter it so that only the sand and the cast iron remain in the pit, which are then removed from there by hand or mechanically. At this facility the following deficiencies made themselves felt. ίο To remove the sand from the pit it is necessary to put the cleaning system out of operation 'until the Water is well filtered. Care should be taken when removing the sand, to reclaim the core and form iron lying between the sand and not destroy them, and finally also so as not to have 'pieces of metal in the re-usable sand. Since the The cleaning system in the Xjebuilding of the cleaning shop is created in the case of new systems, always the difficulty of creating several cesspools one after the other. In this relationship removing the sand from the pit is also very annoying and annoying. In extreme cold, the pit freezes easily during the naphtha comes in and operations are halted the next morning.

Diese Nachteile zu beseitigen, ist Zweck der Erfindung, die im wesentlichen darin besteht, daß das Wassersandgemisch aus einem unterhalb des Putzraumes angeordneten Sumpf mittels Pumpe oder einem entsprechenden Hebewerk ständig herausgefördert wird. Der Sauger der Pumpe oder, z. B. bei einem Paternosterwerk, die Becher gehen dabei zweckmäßig nicht bis auf den Boden, so daß Eisenteile nicht mit erfaßt werden. Andererseits ist die Grube stets begehbar, und die Kern- oder Formeisen können ohne weiteres herausgenommen werden. Der Betrieb der Putzanlage braucht nie unterbrochen werden, während bei Frostwetter die geringe Wassersandgemischmenge abends leicht abgelassen werden kann bzw. genügt ein Heizrohr von geringen Dimensionen, um die geringe Gemischmenge im Sumpf flüssig zu halten bzw. aufzutauen.To eliminate these disadvantages is the purpose of the invention, which essentially consists in that the water-sand mixture from a sump arranged below the cleaning room by means of a pump or a corresponding one Elevator is constantly being conveyed out. The teat of the pump or, for. B. with a paternoster plant, the cups expediently do not go all the way to the floor, so that iron parts are not included. On the other hand, the pit is always accessible, and the core or form irons can be easily removed. The operation the cleaning system never needs to be interrupted, while in freezing weather the low The amount of water sand mixture can be easily drained off in the evening or a heating pipe is sufficient of small dimensions in order to keep the small amount of mixture in the sump liquid or to thaw it.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel in schematischer Darstellung veranschaulicht. α sind die Wände, b der aus einem Rost gebildete Boden des Putzraumes, c stellt einen ein zu putzendes Gußstück d tragenden Wagen dar. Unter dem Putzraum ist eine Grube e, deren Boden den Sumpf/ bildet. In diesen Sumpf/ mündet der Sauger einer Schleuderpumpe g, die durch Welle h von dem Motor i angetrieben wird. Die Pumpe g drückt das Gemisch durch eine Leitung k in einen fahrbaren Behälter /, aus dem das Wasser durch einen Stutzen m abfließen kann.The invention is illustrated in the drawing in an exemplary embodiment in a schematic representation. α are the walls, b the floor of the cleaning room formed from a grate, c represents a wagon carrying a casting to be cleaned d . Under the cleaning room there is a pit e, the bottom of which forms the sump /. In this sump / the suction of a centrifugal pump g, which is driven by the shaft h of the motor i. The pump g pushes the mixture through a line k into a mobile container / from which the water can flow through a nozzle m.

Die Grube e ist in ihrem Teil e1 jederzeit begehbar. Eisenteile, die in den Sumpf gelangen, können also jederzeit bequem von Hand mittels Harke o. dgl. entfernt werden.The pit e is accessible in its part e 1 at any time. Iron parts that get into the sump can easily be removed by hand using a rake or the like at any time.

Eine durch Hahn η abschließbare Rohrleitung ο dient dazu, am Schluß der Arbeitsperiode, z. B. für die Nacht, den Rest des Gemisches aus dem Sumpf herauszulassen.A pipeline ο that can be closed by tap η is used at the end of the working period, e.g. B. for the night to let the rest of the mixture out of the sump.

An Stelle der Pumpe g kann irgendeine andere Hebevorrichtung verwandt werden, z. B. ein Paternosterwerk, Ejektor usw. Durch die Rohrleitung kann das Gemisch auch an eine entferntere Stelle geleitet werden. Die Hebevorrichtung kann verstellbar angeordnet werden, derart, daß sie gesenkt werden kann, um den Sumpf zu entleeren.Any other lifting device can be used in place of the pump g, e.g. B. a paternoster plant, ejector, etc. Through the pipeline, the mixture can also be directed to a more distant point. The lifting device can be arranged to be adjustable so that it can be lowered in order to empty the sump.
