Abstract

The double piston pump for hot molten material with hard pieces embedded in it, particularly bitumen, has two main pistons (1d) which are reciprocated vertically in alternation, so that each can force material through one branch of a bifurcated discharge tube with a common discharge opening (7) at the bottom, each branch also fitted with a hydraulic valve (5) with a valve member (5c) which is raised and lowered vertically in synchronism with the main piston. Immediately above the valve seat is a side inlet for a further valve (3) with a valve member (3c) which reciprocates horizontally to feed material into the chamber under the piston, synchronised with the other valve and the piston.

Description

Vorricktung zur Förderung von breiigen oder in nur heißen Zustand breiige Massen, mit hohen Sand - und Splitteanteilen Die Erfindung betrifft eine Vorrichtung zur Förderung von breiigen'oder in nur heißem Zustand breiige Massen mit hohen Sand-und Splitteanteilen, zum Beispiel Gußasphalt oder andere bituminöse Baustoffe. Vorricktung for pumping pulpy or only in hot condition pulpy masses, with high proportions of sand and grit. The invention relates to a Device for conveying pulpy masses or pulpy masses when they are only hot with high proportions of sand and grit, for example mastic asphalt or other bituminous Building materials.

Dieser Transport wurde bisher in Eimern oder offenen Behtltern zur Verwendungsstelle vorgenommen. Bei Hochbauten werden diese Behalter mit einem Aufzug oder Kran an die Verwendungsstelle gebracht.This transport was previously carried out in buckets or open containers Place of use made. In the case of high-rise buildings, these containers are lifted or brought to the point of use by crane.

Der Erfindung liegt die Aufgabe zugrunde,eine Vorrichtung zur Förderung von breiigen Massen, oder in nur heißem Zustand breiige Massen mit hohen Sand-und Splitteanteilen ,zum Beispiel Gußasphalt oder andere bituminöse Baustoffe , zu schaffen ,bei der ein kontinuierlicher Transport bei hohem Börderdruck gewShrleistet ist.The invention is based on the object of a device for conveying from pulpy masses, or in only hot state pulpy masses with high sand and To create chippings, for example mastic asphalt or other bituminous building materials , in which a continuous transport is guaranteed at high conveying pressure.

Nur ein kontinuierlicher fließender Transport, und dazu ein extrem höher Förderdruck sind Vorraussetzungen,den Transport derartig breiiger Massen durch Rohrleitungen oder Schlauchleitungen zu vollbringen.Just a continuous flowing transport, and an extreme at that higher delivery pressure are prerequisites for the transport of such pulpy masses through To accomplish pipelines or hose lines.

Die Erfindung gewEhrleistet alle diese Vorraussetzungen in der Vorrichtung, in Duplex-Plungerbauart mit hydrostatischer Folge -Steuerung, wobei die Abmessungen der Hydrozylinder und Betriebsdruck der Hydropumpe die extrem hohen Förderdrucke schaffen.The invention ensures all of these prerequisites in the device, in duplex plunger design with hydrostatic sequential control, the dimensions the hydraulic cylinder and operating pressure of the hydraulic pump the extremely high delivery pressures create.

Hydropumpen mit Fördermengenregelung gewShrleisten dazu noch eine stufenlos einstellbare Mengenregelung der Fördermassen zur Verwendungsstelle, ein ganz wesentlicher Vorteil z.B. bei Gußasphalt oder sonstigen heißen Fördermassen durch die Gefahr der Abkühlung an der Verwendungsstelle.Hydraulic pumps with flow rate control also guarantee one more Infinitely adjustable volume control of the conveyed masses to the point of use a very significant advantage, e.g. with mastic asphalt or other hot pumping materials due to the risk of cooling at the point of use.

Eine Ausführungsform der erfindungsgemEßen Vorrichtung ist in der Zeichnung beispielsweise dargestellt.An embodiment of the device according to the invention is shown in FIG Drawing shown for example.

Nicht gezeichnet,ist die erfindungsgemaße Vorrichtung noch elektrisch,oder mit Dampf-oder Thermalöl-Mantelbeheizung auf die betriebstemperatur vorheizbar.Not shown, the device according to the invention is still electrical, or Can be preheated to operating temperature with steam or thermal oil jacket heating.

Alle Teile zur Einführung der breiigen Massen in die Förderzylinder 3,3a,3b,3c und 4,4a,4b,4c sind der besseren Darstellung halber in der Zeichnung um Jeweils 90 Grad zur Seite umgelegt,versetzt gezeichnet.All parts for introducing the pulpy masses into the delivery cylinder 3,3a, 3b, 3c and 4,4a, 4b, 4c are in the drawing for the sake of better illustration Turned 90 degrees to the side, drawn offset.

Die breiigen,oder in nur heißem Zustand breiigen mit hohen Sand-und Splitteanteilen, im folgenden als wFördermassenw bezeichnet, werden in die Gehause 3a und 4a gefüllt.The pulpy, or pulpy in just hot state with high sand and Split parts, hereinafter referred to as wFördermassw, are in the housing 3a and 4a filled.

Der durch Zylinder 1 auf Laterne la,und durch Kolbenstange Ib verbundene Plungerkolben Id im Gehause le, hat in dieser ausgefahrenen Stellung ,und Druckventil 5c wird über Kolbenstange 5b und FUhrungsgehtuse 5a durch Zylinder 5 geschlossen.Connected by cylinder 1 on lantern la, and by piston rod Ib Plunger Id in the housing le, has in this extended position, and pressure valve 5c is closed by cylinder 5 via piston rod 5b and guide gate 5a.

Im Rückzug von Zylinder 3 und Kolbenstange 3b wird das Plattenkolbenventil 3c im Hubbereich - X - geöffnet.When cylinder 3 and piston rod 3b retract, the plate piston valve opens 3c in the stroke area - X - open.

Die Fördermassen füllen den unten zylindrisch geformten Teil von Gehause 3a, und im Vorschub von Zylinder 3 und damit Plattenkolbenventil 3c ,dazu gleichzeitig im Rückzug von Plungerkolben ld durch Zylinder 1 , wird das Förderteil im Gehäuse le zwangsweise gefüllt, und gleichzeitig der Einlauf durch Plattenkolbenventil 3c fest verschlossen. s.Zeichnung) Während des Füllvorganges im Bereich der Positionen 1 - 3 - 5 erfolgt der Fördervorgang im Bereich der Positionen 2 - 4 - 6 Der genaue Wechsel-Rythmus der hydrostatischen Folgesteuerung gewShrleistet die kontinuirliche Förderung unter gleichbleibendem hohen Förderdruck.The conveying masses fill the part of the housing, which is cylindrically shaped at the bottom 3a, and in the advance of cylinder 3 and thus plate piston valve 3c, at the same time In the retraction of plunger ld by cylinder 1, the conveyed part is in the housing le forcibly filled, and at the same time the inlet through plate piston valve 3c tightly closed. see drawing) During the filling process in the area of the positions 1 - 3 - 5 the conveying process takes place in the area of positions 2 - 4 - 6 The exact The alternating rhythm of the hydrostatic sequence control ensures the continuous one Conveyance under consistently high conveying pressure.

Die Druckventil-Einheiten 5,5a,5b,5c und 6,6a,6b,6c führen ebenfalls im Wechsel.Rythmus zu den Plungerkolben id und 2d die Fördermassen in den gemeinsamen Sammler zum Ausgang 7 und damit in die Förderleitung.The pressure valve units 5, 5a, 5b, 5c and 6, 6a, 6b, 6c also lead alternating rhythm to the plunger id and 2d the conveyed masses in the common Collector to exit 7 and thus into the delivery line.
