Description
Pumpe für Gußasphalt und Dickstoffe Die Erfindung betrifft eine Vorrichtung zur Förderung von Gußasphalt und ähnlichen Medien, und ist eine Vorrichtung dieser Art bisher nicht bekannt.Pump for mastic asphalt and thick matter The invention relates to a device for conveying mastic asphalt and similar media, and is a device of this Species not yet known.
Gußasphalt, ein Produkt bestehend aus einem Bindemittel und hochprozentigen Anteilen an Kalkmehl,Sand und Splitt, und Temperaturen bis maximal 270° Celsius,wurde bisher nur in Eimer getragen oder entsprechenden offenen Behälter transportiert.Mastic asphalt, a product consisting of a binder and a high percentage Shares of lime powder, sand and grit, and temperatures up to a maximum of 270 ° Celsius so far only carried in buckets or transported in corresponding open containers.
Demgegenüber bietet die Erfindung die Möglichkeit,diese Massen durch Rohrleitungen zu fördern und unter Uberdruck stehende Behälter zu füllen.In contrast, the invention offers the possibility of these masses To convey pipelines and to fill containers under excess pressure.
Die Erfindung ist in den beigefügten Zeichnungen Blatt(l) und Blatt(2)in einem Beispiel dargestellt: Blatt(l)der Erfindung zeigt die Vorrichtung,bestehend aus dem Arbeitszylinder I mit Hohlkolben,unterem Einlaßventil und darüber angeordneter Druckscheibe, dem Arbeitszylinder II mit Kolbenstange und unterem Auslaßventil, dem Förderzylinder III mit überbauter Einlaufwanne,die vollummantelt mit Wärmeträgeröl oder einem sonstigen Heizmedium aufgeheizt wird, Die Arbeitszylinder I und II sowie der Förderzylinder III werden gemeinsam durch eine pneumatische Folgesteuerung oder eine mechanisch-pneumatische Steuerung automatisch wie folgt gesteuert, in einer stetig fortlaufenden Reihenfolge: Einlauf des Gußasphaltes bei "A" in die Einlaufwanne des Förderzylinders III. Dann Druckbeaufschlagung des Arbeitszylinder I im Anschluß 1 - das Einlaßventil öffnet wobei gleichzeitig die oberhalb angeordnete Druckscheibe den Gußasphalt in den Förierzylinder III drückt.The invention is illustrated in the accompanying drawings sheet (1) and sheet (2) in FIG an example shown: Sheet (1) of the invention shows the device, consisting from the working cylinder I with hollow piston, lower inlet valve and above arranged Thrust washer, the working cylinder II with piston rod and lower exhaust valve, the delivery cylinder III with overbuilt inlet trough, which is fully encased with heat transfer oil or another heating medium, the working cylinders I and II as well as the delivery cylinder III are jointly controlled by a pneumatic sequence control or a mechanical-pneumatic control automatically controlled as follows, in one Continuous sequence: The mastic asphalt is poured into the inlet trough at "A" of the delivery cylinder III. Then pressurization of the working cylinder I in the connection 1 - the inlet valve opens and at the same time the pressure disc located above pushes the mastic asphalt into the forging cylinder III.
Nun Druckbeaufschlagung Arbeitszylinder I im Anschluß 2 - das Einlaßventil schließt.Now pressurization of working cylinder I in port 2 - the inlet valve closes.
Alsdann durch Anschluß 3 Auffüllung des Förderzylinders III mit Preßluft voreingestellter Verdichtung, und nach Erreichen dieses Druckwertes,Beaufachlagung durch Anschluß 4 des Arbeitszylinders 11 - Pumpe für Gußasphalt und Dickstoffe - das Auslaßventil öffnet und läß den Gußasphalt in die Rohrleitung "B" fließen, zeitlich derart begrenztsdaß-keine Preßluft in die Rohrleitung entweichen kann.Then through connection 3 the feed cylinder III is filled with compressed air preset compression, and after reaching this pressure value, additional pressure through connection 4 of the working cylinder 11 - Pump for mastic asphalt and thick matter - the outlet valve opens and lets the mastic asphalt into the pipeline "B" flow, limited in time, so that no compressed air can escape into the pipeline can.
Nunmehr Beaufschlagung durch 5 des Arbeitszylinders -II -.das Außlaßventil schließt, und folgend entlüften des Förderzylinders IIIdurch Austritt 3.Now acted upon by 5 of the working cylinder -II -.das outlet valve closes, and then vent the delivery cylinder III through outlet 3.
Alsdann fortlaufender Folgebeginn wie oben.Then a continuous follow-up as above.
In Weiterführung der Rohrleitung "B" zeigt Blatt(2) der Zeichnung das Befüllen unter überdruck stehender Behälter mit der Erfindung.In continuation of the pipeline "B" shows sheet (2) of the drawing the filling of pressurized containers with the invention.
Dabei kann der gezeigte Behälter in unm'i;ttelbarem Anbau an die Vorrichtung oder in beliebigem Abstand an die Rohrleitung "B'§ angeschlossen sein.The container shown can be attached directly to the device or connected to pipeline "B'§ at any distance.
Der durch die Vorrichtung nach Blatt(l) geförderte Gußasphalt tritt bei 7 Blatt(2) in den Behälter ein. Dabei steht durch Anschluß 8 ein,unter dem Förderdruck liegender, Luftüberdruck im Behälter demzufolge verdichteter Gußasphalt kontinuirlich bei lo austritt, wobei der Mengenautritt durch Steuerschieber 9 geregelt wird.The mastic asphalt conveyed by the device according to sheet (1) occurs at 7 sheets (2) in the tray. There is a through port 8, under the delivery pressure Lying, excess air pressure in the container consequently compacted mastic asphalt continuously exits at lo, the amount entering being regulated by control slide 9.
