Description
Technischer BereichTechnical part
Die vorliegende Erfindung betrifft die Schlammentwässerung und insbesondere eine im Chargenmodus arbeitende Schlammentwässerungsvorrichtung.The The present invention relates to sludge dewatering, and more particularly to one batch mode sludge dewatering apparatus.
Technischer HintergrundTechnical background
Die Entsorgung von Abwasserschlamm wird aufgrund der immer strenger werdenden Umweltschutzvorschriften immer bedeutender. Ein allgemeiner Lösungstyp zur Bewältigung von solchem Abfall ist der in unserem US-Patent Nr. 5,566,469 offenbarte Entwässerer. Dieser Entwässerer ist zwar für seinen beabsichtigten Zweck wirksam und wirtschaftlich, aber es gibt noch großen Verbesserungsspielraum in Bezug auf die Effizienz und die Kosten sowie in Bezug auf die Durchsatzkapazität der Vorrichtung.The Disposal of sewage sludge is becoming ever stricter due to the ever increasing Environmental regulations are becoming increasingly important. A general one solution type to cope such waste is that disclosed in our U.S. Patent No. 5,566,469 Dehydrator. This dehydrator is indeed for its intended purpose is effective and economical, but it are still big Room for improvement in terms of efficiency and costs as well as with regard to the throughput capacity of the device.
Ein weiteres Entwässerungsmittel ist im US-Patent Nr. 3,800,865 offenbart. Das US-Patent Nr. 3,800,865 stellt eine Entwässerungsvorrichtung gemäß Definition im Oberbegriff von Anspruch 1 bereit.One another dehydrating agent is disclosed in U.S. Patent No. 3,800,865. U.S. Patent No. 3,800,865 provides a dewatering device as defined in the preamble of claim 1 ready.
Ein
Problem mit der
Die vorliegende Erfindung stellt einen im Chargenbetrieb arbeitenden Schlammentwässerer gemäß Definition im unabhängigen Anspruch 1 bereit, auf den nunmehr Bezug genommen werden sollte.The The present invention provides a batch operation Sludge dewater as defined in the independent Claim 1, to which reference should now be made.
Zusammenfassung der ErfindungSummary of the invention
Der Schlammentwässerer der vorliegenden Erfindung beinhaltet ein System, das mit indirekter Wärme und einem Chargenmodus erheblich verbesserte Leistungen im Hinblick auf die Schlammentwässerung erzielt.Of the sludge dehydrator The present invention includes a system that uses indirect heat and a batch mode significantly improved performance in terms on the sludge dewatering achieved.

FUNKTIONSPRINZIPIEN. Das zu trocknende Gut wird in den Gutvorrat/Einfülltrichter gegeben. Eine automatische Schiebetür befindet sich innerhalb der Entwässerungskammer an der Guteinlassöffnung, die öffnet, wenn die Einheit gefüllt wird, und schließt, wenn die Einheit im Entwässerungs- oder Ausgabemodus ist. Der Trichter füllt die Entwässerungskammer bis zum korrekten Stand auf der Basis eines vorbestimmten Zeitintervalls. Nach dem Füllen der Entwässerungskammer beginnt der Entwässerungsvorgang mit einer Rührerrotation in der richtigen Richtung und mit dem Pumpen des erhitzten Fluids durch die Entwässerungskammer und den Rührer. Zu Beginn des Trocknungszyklus wird, wenn das Gut den nassesten Zustand erreicht hat, das Wärmefluid auf einer höheren Temperatur gehalten. Gegen Ende des Zyklus wird, wenn das Gut trockener ist, die Temperatur des Öls reduziert, damit sie den Zündpunkt nicht erreicht. Dadurch wird ein Versengen oder Verbrennen des Gutes verhütet. Im Entwässerungsmodus arbeiten die flachen Seiten der Wischerröhren in Richtung auf das Gut. Während dieser Periode wird das Gut ständig gerührt, angehoben und umgewälzt, damit so viel der erhitzten Oberflächen der Rührerrohre, Scheiben und Zylinderwände wie möglich damit in Kontakt kommt. Wenn festgestellt wurde, dass das Gut trocken ist, entweder nach einem zeitlich begrenzten Zyklus oder mit Hilfe eines Temperatursensors, dann öffnet das System automatisch die Gutauslassöffnungstür und kehrt die Richtung des Rührers um, so dass die abgewinkelten Fördererstäbe in Richtung auf das Gut arbeiten. Bei jeder Umdrehung bewegen die abgewinkelten Förderstäbe das Gut in Richtung auf und durch die Auslassöffnung und geben es auf den Trockengutförderer. Das trockene Material wird vom Förderer zu einem Behälter oder zu einem Sack befördert. Wenn der Entwässerer leer ist, dann schließt das System automatisch die Auslassöffnungstür und füllt es erneut mit nassem Gut, um mit dem nächsten Entwässerungszyklus zu beginnen. Da das System geschlossen ist, ist das Abgas aus dem Entwässerer praktisch reiner Dampf. Der Luftwäscher/Verdichter hat die Aufgabe, Partikel zu entfernen, die möglicherweise im Abgasstrom mitgeführt wurden, um so viel von dem Dampf wie möglich wieder zu einer Flüssigkeit zu kondensieren.PRINCIPALS. The material to be dried is placed in the stock / hopper. An automatic sliding door is located inside the drainage chamber at the Guteinlassöffnung, that opens, when the unit is filled will, and will close, if the unit is in the drainage or output mode is. The funnel fills the drainage chamber to the correct level based on a predetermined time interval. After filling the drainage chamber the drainage process begins with a stirrer rotation in the right direction and with the pumping of the heated fluid through the drainage chamber and the stirrer. At the beginning of the drying cycle, when the product is wetest State has reached the heat fluid at a higher level Temperature maintained. Towards the end of the cycle, when the commodity becomes drier is the temperature of the oil reduced, so that the ignition point not reached. This will cause a scorching or burning of the goods prevented. In drainage mode work the flat sides of the wiper tubes towards the estate. While In this period the estate becomes permanent touched, raised and recirculated, so that as much of the heated surfaces of the stirrer tubes, slices and cylinder walls as possible with it comes into contact. If it was determined that the goods are dry is, either after a temporary cycle or with help a temperature sensor, then opens the system will automatically open the Gutauslassöffnungstür and the direction of the stirrer around, leaving the angled conveyor bars in the direction work on the estate. At each turn, the angled move Conveyor rods the good towards and through the outlet opening and give it to the Trockengutförderer. The dry material is from the conveyor to a container or transported to a sack. If the drainer is empty, then closes the system automatically opens the outlet port door and refills it with wet material, with the next dewatering cycle to start. Since the system is closed, the exhaust gas is from the dehydrator practically pure steam. The air scrubber / compressor has the task of particles to remove that possibly entrained in the exhaust stream were as much of the steam as possible back to a liquid to condense.
