Abstract

To give a controlled settling of a dungheap, the dung is fed to the lower section of the heap and it is aerated from below. Also claimed is an assembly from a dung channel with a conveyor (4) for the dung to the dung storage (6) area. Its outlet is below the dungheap (7), and it has a fan (11) to impel air. One or more air outlet openings are below the heap. USE/ADVANTAGE - The system is for the disposal of dung from cattle sheds, etc., to be held in a heap. The operation ensures that the lower section of the heap decomposes consistently and that smells are contained.

Description

Die Bereitung von Festmist (Exkremente und Einstreu) in einem Dungstapel führt bekanntlich zu einer Geruchsbelästigung. Diese ist besonders stark, wenn der frische Stalldung aus der tägli­ chen Entmistung lose auf einen Haufen abgekippt wird. Das Be­ schicken oder das Einlagern des Stalldung von oben auf den Sta­ pel führt auch dazu, daß die unteren Lagen stärker verrotten als die oberen. Diese Nachteile werden bekanntlich weitgehend vermieden, wenn der Stapel von unten beschickt wird; der frische Stalldung wird nach oben gegen den darüberlagernden, älteren ausgedrückt. Auf diese Weise wird erreicht, daß der starke Geruch des frischen Dungs durch den darüberliegenden absorbiert wird. Außerdem entsteht ein Stapel hoher Verdichtung.The preparation of solid manure (excrement and bedding) in one Manure piles are known to cause odor nuisance. These is particularly strong when the fresh manure from the daily the manure is loosely dumped onto a pile. The Be send or the storage of the manure from above onto the Sta pel also causes the lower layers to rot more than the top. As is well known, these disadvantages become extensive avoided if the stack is loaded from below; the fresh manure is up against the overlying, expressed older. In this way it is achieved that the strong smell of the fresh manure due to the overlying is absorbed. It also creates a stack higher Compression.

Das von Harn stark durchtränkte Stroh besitzt indes für die Rotte einen zu hohen Feuchtegehalt. Zudem reicht der Sauerstoffgehalt in der unteren Stapelzone für eine rasche Rotte nicht aus.The straw soaked in urine, however, has for the Rotting too high a moisture content. In addition, the Oxygen content in the lower stacking zone for a quick Don't eradicate.

Die Rottebedingungen werden erfindungsgemäß dadurch verbessert, daß das Stroh-Kot-Harngemisch auf dem Wege zum Dungstapel abgepreßt wird; der überschüssige Harn fließt in einem Sammelbehälter zurück.According to the invention, the rotting conditions are improved by that the straw-feces-urine mixture on the way to the manure pile is pressed; the excess urine flows in one Collection container back.

Zur Verbesserung der Belüftung wird von unten Luft in den Dungstapel eingepreßt; es bietet sich an, dafür die Dungzuführleitung mit zu benutzen. Der Stapel wird zweckmäßi­ gerweise durch eine Plane abgedeckt und die Abluft durch einen Wäscher geleitet, so daß sie praktisch geruchsfrei austritt.To improve ventilation, air is drawn in from below Manure pile pressed in; it lends itself to that Manure supply line to be used. The stack is expedient partially covered by a tarpaulin and the exhaust air by a Washer directed so that it exits practically odorless.

Dem frischen Stalldung können auf dem Wege zum Stapel ferner Zuschlagstoffe beigefügt werden, welche die Verrottung fördern und die Geruchsbildung mindern. The fresh manure can also be found on the way to the stack Additives are added that promote rotting and reduce odor.  

In den Fig. 1, 2 und 3 ist der Stall 1 mit saugfähiger Einstreu 2, wie z. B. Spleißhäcksel, ausgelegt. Die Tiere treten den Dung 5 in die Rinne 3, in der eine Schnecke 4 umläuft. Die Schnecke 4 fördert den Dung 5 zum Dungplatz 6, der vorzugsweise betoniert ist. Der Dung 5 tritt mittig im Dungplatz 6 nach oben aus; es bildet sich ein Dungstapel 7, der mit der Beschickung von unten hochgedrückt wird. In die Förderschnecke 4 wird über eine Gebläse 11 Luft 12 eingedrückt, die von unten in den Stapel eintritt und ihn belüftet. Der Stapel 7 ist mit einer Plane 8 abgedeckt. Die unter dem Stapel 7 tretende Luft 12 durchströmt den Dungstapel 7, fließt durch einen Wäscher 13 und tritt geruchsfrei aus.In Figs. 1, 2 and 3, the stable 1 with absorbent bedding 2 such. B. splice chop designed. The animals enter the manure 5 into the channel 3 , in which a snail 4 rotates. The screw 4 conveys the manure 5 to the manure site 6 , which is preferably concreted. The manure 5 emerges in the middle of the manure area 6 upwards; a manure stack 7 is formed , which is pushed up with the feed from below. In the screw conveyor 4 11 air 12 is forced through a blower which enters from below into the stack, and it ventilated. The stack 7 is covered with a tarpaulin 8 . The air 12 passing under the stack 7 flows through the manure stack 7 , flows through a scrubber 13 and emerges odorless.

Die Schnecke 4 endet um eine Weglänge a vor dem Austritt; es bildet sich so ein Preßpfropfen 14, aus dem der überschüssige Harn durch den Siebmantel 15 im Bereich a austritt. Der abgepreßte Harn fließt in die darunterliegende Jauchegrube 16, oder wird über einen Kanal in einen dafür geeigneten Behälter abgeleitet oder abgepumpt.The screw 4 ends by a path length a before the exit; a press plug 14 is thus formed, from which the excess urine emerges through the screen jacket 15 in area a. The urine that has been pressed out flows into the septic tank 16 underneath, or is drained off or pumped off via a channel into a container suitable for this.

Das Austragen des Dungs aus dem Stall, wie Fig. 3 zeigt, kann auch mit einer Schubstange 9 erfolgen, die diesen dann der Schnecke 4 übergibt. Dem frischen Dung werden in der Dosier­ station 9 Zuschlagstoffe 10 beigegeben, um die Rotte zu ver­ besssern und die Geruchsentwicklung gering zu halten.The manure can be discharged from the barn, as shown in FIG. 3, with a push rod 9 , which then transfers it to the screw 4 . The fresh manure 9 additives 10 are added in the dosing station to improve the rotting ver and keep the odor low.
