Zusatz zum Patente 221802 vom 22. August 1907.*)Addendum to patent 221802 of August 22, 1907. *)

Patentiert im Deutschen Reiche vom 27. Februar 1908 ab. Längste Dauer: 21. August 1922.Patented in the German Empire on February 27, 1908. Longest duration: August 21, 1922.

In der den Gegenstand des Patents 221802 bildenden Vorrichtung zur Verhinderung des Verstopfens von Schlammversatzleitungen wird die schlamm- oder geschiebehaltige Flüssigkeit zwecks Verhinderung ihrer Entmischung und sicheren Weiterbeförderung mittels motorisch angetriebener Förderrohre, deren Innenseite mit nach Art der Schiffsschraubenflügel ausgebildeten Schaufeln besetzt ist, gleichzeitig durcheinandergemischt und vorwärts getrieben, worauf sie in die feste Leitung mit schraubengangförmigen Zügen von großer Steigung eintritt, die in entgegengesetztem Drehsinne von den Leitschaufel Vorrichtungen verlaufen, damit der Flüssigkeitssäule unter der Druckbzw. Saugwirkung der drehbaren Rohrteile eine verstärkte Achsendrehung verliehen bzw. aufrechterhalten wird.
Die Erfahrung'lehrt nun, daß trotz der sich stetig ändernden Lage der schlamm- oder geschiebehaltigen Flüssigkeit die unten liegenden Teile der Züge zunächst verschleißen, was sich dadurch erklärt, daß die schwereren Gesteinteile trotz der drehenden Bewegung der Flüssigkeit häufiger und anhaltender mit den unteren Teilen der Züge in Berührung treten wie mit den oberen. Ist aber der Verschleiß der unten liegenden Teile der Züge so weit vorgeschritten, daß sie nicht mehr genügend auf die durchgehende Wassersäule auf Drehung einwirken können, so muß die ganze Rohrlänge weggeworfen werden, was bei den oft sehr langen Schlammversatzleitungen einen großen wirtschaftlichen Verlust darstellt. 'In the device for preventing the clogging of sludge backfilling lines, which is the subject of patent 221802, the sludge or slurry-containing liquid is simultaneously mixed up and forward by means of motor-driven conveying pipes, the inside of which is equipped with blades designed in the manner of propeller blades, in order to prevent their segregation and safe further transport driven, whereupon it enters the fixed line with helical trains of great slope, which run in opposite directions of rotation from the guide vane devices so that the liquid column under the pressure or. Suction of the rotatable pipe parts an increased axis rotation is given or maintained.
Experience now shows that, despite the constantly changing position of the fluid containing mud or debris, the lower parts of the trains initially wear out, which is explained by the fact that the heavier rock parts, in spite of the rotating movement of the fluid, more frequently and persistently with the lower parts the trains come into contact as with the upper ones. If, however, the parts of the trains below are worn so far that they can no longer act sufficiently to rotate the continuous water column, the entire length of the pipe has to be thrown away, which is a great economic loss with the often very long mud backing lines. '

Diesen Übelstand zu beseitigen, ist der Zweck der vorliegenden Erfindung, welche eine Verbesserung des Erfindungsgedankens des Patents 221802 in dem Sinne darstellt, daß die Züge oder Führungsrippen nicht mehr mit dem Rohr aus einem Stück bestehen, sondern nach Art der bekannten Verschleißfutter getrennt von diesem hergestellt und in letzterem ausgespart und dann von einem gemeinsamen Rohr umhüllt werden. Die derart getrennt vom Rohr hergestellten Führungsrippen können außerdem noch zur Erleichterung ihrer Herstellung aus den zu sogenannten Verschleißfuttern verwendeten Materialien, wie Porzellan, Glas, Beton u. dgl., und zum bequemen Auswechseln einzeln hergestellt werden. Im letzten Falle empfiehlt sich dann, in jeder Rippe des Verschleißfutters eine metallene Verstärkungsleiste einzubetten, die zum besseren Halt der einzelnen Führungsrippen mit dem gemeinsamen Umhüllungsrohr lösbar verbunden wird.To remedy this drawback is the purpose of the present invention, which is an improvement of the inventive concept of patent 221802 in the sense that the Trains or guide ribs are no longer made in one piece with the pipe, but after Type of known wear lining produced separately from this and cut out in the latter and then enveloped by a common tube. The so separated Guide ribs made from the pipe can also be used to facilitate their production from the materials used for so-called wear liners, such as porcelain, glass, Concrete and the like, and are made individually for easy replacement. In the latter case It is then advisable to have a metal reinforcement strip in each rib of the wear lining to embed, for a better hold of the individual guide ribs with the common Cladding tube is releasably connected.

Diese Neuerung bietet gegenüber der in dem Patent 221802 beschriebenen Rohrleitung den Vorteil, daß nach Erreichung der zulässigenThis innovation offers compared to the pipeline described in patent 221802 Advantage that after reaching the permissible

Claims

Wear limit is no longer the entire length of the pipe worthless, but the latter can be made as good as new by replacing the worn guide ribs with new ones. In addition, this type of design of the helical guide ribs still has the advantage that the whole pipeline can be assembled cheaply and advantageously from such tubes with helical ίο guide ribs, because a wear lining must be used like that and the guide ribs in this embodiment only in a certain sense represent a special embodiment of a wear lining ■. The drawing shows an application of the invention in FIG. 1 in a longitudinal section through a flushing offset line. Fig. 2 shows in cross section a special embodiment of the interchangeable trains. On the normal pipeline α connects to the conical transition piece b, the pipe section c, which has a larger diameter compared to α, by the trains d. to compensate for the contraction of the cross-section. The trains d, which together form roughly the shape of a three-pass or four-pass, now have a slight twist, similar to the gun barrel trains, which is suitable in relation to the speed of the liquid column to give it a simultaneous axis rotation. In addition to the effects already explained, there is also the fact that, even after an interruption in operation, the heavier batch parts of the flushing material deposited on the pipe invert are whirled up again and transported further. In the embodiment of the mixing tube 0 shown in Fig. 2 with interchangeable trains d, the latter are installed as a separate body in a relatively light iron pipe, whereby they overlap each other in some way at the butt joints. On the outer surface of each train d, the metal bar β is embedded, which carries the bolts f, with the help of which the trains d can be attached. By interposing this metal insert e, on the one hand, the durability of the individual pulls d during manufacture, transport and installation is increased, and on the other hand, due to their larger adhesive surface on the material of the pulls, there is no risk of the screw bolts f breaking out. If concrete is used, this reinforcing strip can be brought into connection with a light frame made of iron rods that penetrates the concrete, so that the known effects of reinforced concrete occur. In order to increase the cohesion of the metal insert e with the material of the trains, the same can be provided with a central rib which is undercut in cross section or pierced in paragraphs so that the material in question is tied in at these points. 65 Godfather ν τ-An Proverbs:

1. Pipeline, in particular flushing offset line, for the transport of sludge or debris Liquids according to patent 221802, in which the liquid is passed through internal, helical guide ribs an axis rotation is given, characterized in that the guide ribs in the well-known wear lining ■ (concrete, porcelain, glass) of the pipeline are. ·.

2. Embodiment of the pipeline according to claim 1, "characterized in that metal reinforcement strips are embedded in the ribs of the wear lining, which are connected to the outer tube at the same time.
