Abstract

Mixer and homogen iser for channels and storage tanks of fibre contg. media consists of a stirring and milling shaft which can be mounted perpendicularly, transversely or along the flow channel and can be directly or indirectly driven. The stirring and tearing element should pref. be a screw having movable or fixed reducing elements to saw or cut. Before and after the shaft can be mounted control plates, one of which can be mounted inclined across it. Several shafts can be mounted close to each other. The shafts can have continuous or broken outer shells, or be led through cylindrical or conical tubes, the liquid being forced through. They can be mounted perpendicular to the flow and can have fixed or flexible drives, in either movable or inclinable mounting. The appts is used for stirring and homogenising fibrous suspensions esp. sewage. Modern sewage works rely on accelerated digestion which is only possible with homogeneous, finely dispersed sewage. Various means are available to achieve this but current systems are expensive to install, do not work effectively, are costly to maintain and tend to be damaged by attack from the sewage. The system claimed gives improved performance on all these counts.

Description

RÜHRWERK und VERFLÜSSIOUNGSSYSTEM für Känale und Lagerbehälter faserhaltiger Medien.STIRRER and LIQUIDATION SYSTEM for canals and storage tanks containing fibers Media.

vornehmlich Flüßigmist. mainly liquid manure.

Die Erfindung betrifft eine Einrichtung zum aufbereiten, homigenisieren wie verflüßigen dicker wie faserhaltiger Medien, die als Schweemm- oder Treibgut, über Kanäle oder Schächte zu Sammel- oder Lagerbehälter geleitet werden. The invention relates to a device for processing, homigenizing How do thick or fibrous media liquefy, which are floating or floating debris, be routed via channels or shafts to collection or storage containers.

Es ist bekannt, daß a1rs der heuzeitlichen Stallhaltung, wie Fäkalien-Abwässerbeseitigung anfallende dicke Medien, faserhaltige Langteile wie Einstreu und Futterreste über Kanäle oder leitungen zu Sammelbehälteren geleitet werden. It is known that a1rs of modern stable keeping, such as faecal sewage disposal accumulating thick media, fiber-containing long parts such as litter and leftover feed Channels or lines are routed to collecting tanks.

Je nach Umfang und Anfall sind hierzu teils große Längen ohne Gefälle-Treibmistverfahren - oder mit ganz geringem Gefälle - Lage- oder gelände bedingt, erforderlicht über die die Medien sich zu den Sammelbehältern bewegen müßen/sollen. Depending on the volume and the amount, sometimes long lengths are required without the use of sloping drifting manure - or with a very slight gradient - depending on the location or terrain, required over that the media must / should move to the collection containers.

Hieraus resultieren erfahrungsgemäß Störungen. als gerade Faserhaltige Medien und Anfall begren7ter bezwinctend lagergemäß geringer Flüßigkeitsanteil, den reibungslosen kontinuierlichen Ablauf behindern. Dies Ixmsomehr, als z.B. die neue Stallhaltung, Boxenlaufstall u.ä., die verstärkte Zugabe von Einstreu erfordern, noch unerwartet große Futterreste zu den LauF- und Kotablagerungsplätzen der Tiere gelangen sind somit der Entmistung Zukommen. Experience has shown that this results in malfunctions. than those that contain fibers Media and accumulation of limited liquid content according to the storage conditions, hinder the smooth, continuous process. This is more than e.g. New stable housing, box playpen, etc., which require more litter to be added, still unexpectedly large remains of food to the running and droppings of the animals have come to the manure removal.

Im weiteren bilden die unter Abs.4 auftretenden Langteile in den teils großen Sammelbehältern Schwimm- und Sinkschichten. Furthermore, the long parts appearing under Paragraph 4 in the partly large collecting tanks floating and sinking layers.

die während der möglichen Einlacrerunaszeit nicht verrotten. which do not rot during the possible Einlacrerunaszeit.

-a~ Hierzu werden sehr wohl schwer bewegliche Pumpen verwendet, die über nicht lange wirckungsvolle Reiß- und Schneideinrichzungen im Umwälzverfahren die langen Fremdkörper als fasserhaltige Medien aufbereiten sollen, wozu besonders Vorgruben im Rücklaufverfahren, dienen.-a ~ For this purpose, pumps that are difficult to move are used about not long effective tearing and cutting devices in the circulation process the long foreign bodies should be processed as media containing bulk, for which purpose especially Pre-pits in the return process, serve.

-b- Es sind auch Einsteckrührwerke bekannt, die mit hochtourialaufenden Flügeln-messern oder kleinen Förderschnecken, sozusagen vermixen und homogenisieren sollen.-b- There are also known plug-in agitators that run at high speeds Blend and homogenize wing knives or small screw conveyors, so to speak should.

-c- Im weiteren sind auch pneumatische oder lanasamlaufende Rührwerke bekannt.-c- There are also pneumatic or lanasam running agitators known.

-d- Ebenso Tankfahrzeuge, die Rührwellen mit einer gleichzeitig verbundenen Verteilervorrichtung eingebaut haben, auf der Rühr- oder Reißwerke bezwingend Messer montiert sind.-d- Likewise, tank trucks that have agitator shafts connected to one at the same time Have installed distribution device, on the agitators or tearing mechanisms compelling knives are mounted.

Diese unter -a- bis -d- bekannten und gerannten Rin- oder Vorrichtungen haben im Besonderen den wesentlichen Nachteil, daß diese sehr teuer sind, nach kurzer Zeit oder gar nicht wirkungsvoll arbeiten, reparaturanfällig oder durch getrernte Lagerhaltung Harn und Wasser, wie Stapelmist - 7,U d - von dem neuzeitlichen und arbeitswirtschaftlichen Verfahren der Treib-und Schwemmentmistung abweichen.These under -a- to -d- known and run Rin- or devices in particular have the major disadvantage that they are very expensive after a short time Time to work effectively or not at all, prone to repairs or disconnected Storage of urine and water, such as staple manure - 7, U d - from the modern and work management procedures of drifting and alluvial manure differ.

Weiterhin erforderert z.B. die neue Dürgewirtschaft, daß z.B.Furthermore, e.g. the new drought economy requires that e.g.

Einstren und Futterreste schnell verrotten, was nur im kleinen homogenen Zustande entsprechend der kurz befristeten Lagerung möglich ist, entsprechend beschränktem teurem Lager/Sammelraum, noch daß große faserhaltige und dicke Medien Aufbereitung und Ausbringung nicht stören, bezwingend im kleinsten Zustande zur Kopfdüngung gelangen.Stren and leftover feed rot quickly, which is only in the small homogeneous Conditions corresponding to the short-term storage is possible, correspondingly limited expensive storage / collection room, nor that large fibrous and thick media preparation and application do not interfere, compellingly to get top dressing in the smallest state.
