Description
Schraubenschaufler-Umwälzvorrichtung Bei Schraubenschaufler-Umwälzapparaten, die in Faulschlamm arbeiten und bei denen das Schaufelrad gegen in seinem Gehäuse vorgesehene Messer fördert, die - zum Zerschneiden von im Faul schlamm vorhandenen zähen Stoffen, wie Lappen, Putzwolle u. dgl., dienen, kommt es vor, daß zeitweise sehr starke Motorleistungen erforderlich sein würden, um das Zerschneiden. solcher Zähstoffe durchzuführen und Verstopfungen zu verhindern. Große Motoren, welche zur Aufbringung dieser Leistungen in der Lagè-sein würden, verwendet man aber aus wirtschaftlichen Gründen sehr ungern. Die Erfindung hat den Zweck, dieselben zu vermeiden und die Möglichkeit zu schaffen, Verstopfungen auf andere Weise zu beseitigen, so daß man mit einem Motor auskommt, der dem Kraftbedarf des normalen Betriebs entspricht.Screw shovel circulating device For screw shovel circulators, who work in digested sludge and where the paddle wheel against in its housing provided knife promotes, which - for cutting up existing in the sludge tough materials such as rags, cleaning wool and the like, it happens that at times very powerful engine powers would be required to do the chopping. such Carry out toughening and prevent constipation. Big engines, which for These services would be able to provide these services, but are used for economic reasons Very reluctant to set up. The invention has the purpose of avoiding the same and the To create an opportunity to clear blockages in other ways, so that one gets by with a motor that corresponds to the power requirements of normal operation.
Die Erfindung besteht darin, daß die Welle des Laufrades im Motoruntersatz abgekantet und ein Schlüssel vorgesehen ist, durch den die Welle von Hand bei vorkommenden Verstopfungen weitergedreht werden kann. The invention consists in that the shaft of the impeller in the motor base beveled and a key is provided through which the shaft is by hand when occurring Blockages can be turned further.
Auf der Zeichnung (Abb. 1) ist ein Ausführungsbeispiel der Erfindung im Schnitt durch den Motoruntersatz und das Schauflergehäuse dargestellt. On the drawing (Fig. 1) is an embodiment of the invention shown in section through the motor base and the shovel housing.
In dem das Gehäuse des Schaufelrades a. bildenden Rohrstück b ist ein an radialen Leitwänden c gehaltenes Führungslager d für die Schaufelradwelle e vorgesehen. In die Leitwände c sind unten scharfe Messer f eingesetzt, deren Schneiden gegen das Schaufelrad a gerichtet sind, wie in Abb. 2 im Schnitt nach Linie A-B der Abb. 1 ersichtlich ist. In which the housing of the paddle wheel a. forming pipe section b is a guide bearing d, held on radial guide walls c, for the impeller shaft e provided. In the guide walls c sharp knives f are used below, their cutting are directed towards the paddle wheel a, as in Fig. 2 in the section along line A-B Fig. 1 can be seen.
Erfindungsgemäß nun ist das Motoruntersatzgehäuse g auf einer Seite mit einer Durchbrechung h versehen, und unmittelbar unter dem Führungsjager i ist die Welle e des Schaufelrades bei k abgekantet, so daß an dieser Stelle ein Schlüssel I angesetzt werden kann. Vdr'teilhaft verwendet man ein Sechskant oder Achtkant, die dem Vierkant gegeniiber den Vorteil bieten, daß die Welle nur wenig geschwächt wird und man von einer Seite in allen Stellungen des Schaufelrades den Schlüssel ansetzen kann. According to the invention, the motor base housing g is now on one side provided with an opening h, and is immediately below the guide hunter i the shaft e of the paddle wheel bevelled at k, so that a key at this point I can be set. A hexagon or octagon is sometimes used, which have the advantage over the square that the shaft is only slightly weakened and you hold the key from one side in all positions of the paddle wheel can start.
