Description
Anordning til fremstilling av et jord-forbedrinqsmiddel Device for the production of a soil improvement agent
Foreliggende oppfinnelse angår en anordning til fremstilling au et jordforbedringsmiddel . The present invention relates to a device for producing a soil conditioner.
Ved rensing au avfallsvann fås store mengder slam som i betydelig grad inneholder stoffer som er ytterst egnet som gjødning. Slikt slam er allikevel temmelig tungt å hånd-tere og illeluktende. When cleaning waste water, large quantities of sludge are obtained, which to a significant extent contain substances that are extremely suitable as fertiliser. Such sludge is nevertheless rather heavy to handle and stinks.
Formålet med foreliggende oppfinnelse er å.skaffe en anordning til fremstilling av jordforbedringsmidler som inneholder slam som en hovedkomponent. The purpose of the present invention is to provide a device for the production of soil conditioners that contain sludge as a main component.
Anordningen ifølge oppfinnelsen løser denne oppgave ved at den har de karakteristiske trekk som fremgår av de etterfølgende krav. The device according to the invention solves this task in that it has the characteristic features that appear in the subsequent claims.
Ved hjelp av anordningen ifølge oppfinnelsen er det muliggjort en økonomisk utnyttelse av slam fra renseverk for avfallsvann. Ved å blande inn i slammet f.eks. bark, fortrinnsvis bark fra bartrær, torv eller lignende, får slammet en lett håndterlig form, lukten elimineres, nitrogenet i slammet bevares og man oppnår et jordforbedringsmiddel med stort humusinnhold. With the aid of the device according to the invention, economic utilization of sludge from wastewater treatment plants has been made possible. By mixing into the sludge, e.g. bark, preferably bark from coniferous trees, peat or the like, gives the sludge an easily manageable form, the smell is eliminated, the nitrogen in the sludge is preserved and a soil conditioner with a high humus content is obtained.
Anordningen monteres fortrinnsvis på et bevegelig understell, f.eks. en tilhenger vogn, idet anordningen kan få sin drivkraft fra trekkjøretøyet eller fra en egen kraftenhet som drives f.eks. av en forbrenningsmotor. På denne måten er anordningen alt etter behov forflyttbar fra et sted til et annet og også uavhengig av en ytre kraftkilde. Anordningen kan også omfatte en drivanordning som muliggjør en automatisk forflytning av anordningen i retning av komposthaugen. The device is preferably mounted on a movable undercarriage, e.g. a trailer, as the device can get its driving force from the towing vehicle or from a separate power unit that is driven e.g. of an internal combustion engine. In this way, the device can be moved from one place to another as needed and also independent of an external power source. The device can also comprise a drive device which enables an automatic movement of the device in the direction of the compost pile.
Matningshastighetene for anordningene som mater slam og andre komponenter fra beholderne, er fortrinnsvis innstillbare uavhengig av hverandre, idet jordforbedringsmiddel med flere forskjellige sammensetninger kan fremstil-les. Plateranordningene omfatter fortrinnsvis transportskruer som muliggjør en særlig jevn matning. Av samme grunn omfatter også b1 andeanordni ngen fortrinnsvis' transportskruer, f.eks. to parallelle skruer, men også blandeanordninger av en annen type kan tenkes. The feed rates for the devices that feed sludge and other components from the containers are preferably adjustable independently of each other, as soil conditioners with several different compositions can be produced. The plate arrangements preferably include transport screws which enable a particularly even feeding. For the same reason, the other device also preferably includes transport screws, e.g. two parallel screws, but mixing devices of another type are also conceivable.
Materanordningene og blandeanordningen er fortrinnsvis hydraulisk drevet. The feeding devices and the mixing device are preferably hydraulically driven.
I det følgende skal oppfinnelsen beskrives nærmere under henvisning til tegningene, hvor fig. 1 og 2 viser en utførelse av oppfinnelsen, fig. 3 og 4 viser en annen utførelse av oppfinnelsen og fig. 5 viser i detalj en foretrukket utførelse av en transportskrue for blandeanordningen. In what follows, the invention will be described in more detail with reference to the drawings, where fig. 1 and 2 show an embodiment of the invention, fig. 3 and 4 show another embodiment of the invention and fig. 5 shows in detail a preferred embodiment of a transport screw for the mixing device.
På fig. 1 og 2 er anordningen til fremstilling av jordforbedringsmiddel montert på en tilhenger vogn 8 som kan kobles f.eks. til en traktor. In fig. 1 and 2, the device for producing soil conditioner is mounted on a trailer cart 8 which can be connected, e.g. to a tractor.
Bark, torv, halm, tørt løv eller annet egnet karbonholdig materiale lastes f.eks. ved hjelp av en lastemaskin opp i en beholder 1, på hvis bunn er anordnet et transportbånd la. Båndet la mater materialet til en transportskrue 2 som mater materialet videre til innløpet for en riveanordning 3. Til separering av altfor store og harde stykker fra materialet er ri vean.ordningen forsynt med et i og for seg kjent separerings-organ 3a. Riveanordningen river barken osv. til ønsket stør-relse og mater den til innløpet for en blandeanordning 4. Bark, peat, straw, dry leaves or other suitable carbon-containing material are loaded, e.g. by means of a loading machine into a container 1, on the bottom of which is arranged a conveyor belt la. The belt feeds the material to a transport screw 2 which feeds the material on to the inlet for a shredding device 3. To separate excessively large and hard pieces from the material, the shredding device is equipped with a separation device 3a known per se. The shredding device shreds the bark etc. to the desired size and feeds it to the inlet for a mixing device 4.
Slam som kommer f.eks. fra et avfallsvann-renseverk, lastes inn i en beholder 5, ved hvis bunn er anordnet et transportbånd 5a. Båndet 5a mater slammet til en transportskrue 6 som mater sl,ammet videre til innløpet for blandeanordningen 4. Blandeanordningen 4 omfatter to parallelle transportskruer 4a og 4b som blander slammet med tilsatskomponenten og mater den således fremkomne blanding til et skovlhjul som er anordnet ved utløpet fra blandeanordningen. Skovlhjulet 7 slynger jord-forbedringsmidlet til en haug eller stabel bak anordningen, hvorved materialet samtidig løses opp. Sludge that comes e.g. from a waste water treatment plant, is loaded into a container 5, at the bottom of which a conveyor belt 5a is arranged. The belt 5a feeds the sludge to a transport screw 6 which feeds the sludge on to the inlet of the mixing device 4. The mixing device 4 comprises two parallel transport screws 4a and 4b which mix the sludge with the additive component and feed the resulting mixture to a paddle wheel which is arranged at the outlet from the mixing device . The bucket wheel 7 slings the soil improvement agent into a pile or stack behind the device, whereby the material is simultaneously dissolved.
Fig. 3 og 4 uiser en annen foretrukket utførelse au oppfinnelsen. Bark eller annen karbonholdig komponent lastes inn i en beholder 9, hvorfra en transportskrue som er anordnet på beholderens bunn, mater komponenten til en tverrgående skrue 11. Slam skylles opp i en beholder 14, hvorfra en transportskrue 15 som er anordnet på beholderens bunn, Fig. 3 and 4 show another preferred embodiment of the invention. Bark or other carbonaceous component is loaded into a container 9, from which a transport screw arranged on the bottom of the container feeds the component to a transverse screw 11. Sludge is rinsed up into a container 14, from which a transport screw 15 arranged on the bottom of the container,
mater slammet til den tuerrgående skrue 11. Skruen 11 mater begge komponenter eller forhåndsblanding til innløpet til en riueanordning 12 som er forsynt med et organ til separering au slike stykker fra blandingen som er for store og for harde til å inkluderes i jordf orbédringsmidlet. Fra riveanordning-en 12 tilføres materialet en blandeanordning 13 som fortrinnsvis omfatter to parallelle transportskruer 13a og 13b. Ved ut-løpet fra blandeanordningen er anordnet et skoulhjul eller lignende som slynger jordforbédringsmidlet til en stabel eller haug, hvor det således oppløste og luftede materiale kompost-eres. feeds the sludge to the two-way auger 11. The auger 11 feeds both components or premix to the inlet of a sieve device 12 which is provided with a means for separating such pieces from the mixture as are too large and too hard to be included in the soil improver. From the shredding device 12, the material is fed to a mixing device 13 which preferably comprises two parallel transport screws 13a and 13b. At the outlet from the mixing device, a scoop wheel or the like is arranged which slings the soil improvement agent into a stack or pile, where the thus dissolved and aerated material is composted.
Som uist på fig. 5, omfatter blandeanordningens transportskrue 13a og 13b fortrinnsuis en spiralformet skrue som er festet til en rørformet aksel 19 og forsynt med fremstikkende blader 21 for utførelse av blandingen av materialet. Antallet, utformningen og orienteringen au bladene 21 kan varieres etter forskjellige materialer. As shown in fig. 5, the transport screw 13a and 13b of the mixing device comprises a spiral screw attached to a tubular shaft 19 and provided with protruding blades 21 for carrying out the mixing of the material. The number, design and orientation of the blades 21 can be varied according to different materials.
Selv om begge blandeanordningene 4 og 13 er vist forsynt med to skruer, skal det bemerkes at et tilfredsstillende resul-tat ofte kan oppnås med bare en blandeskrue som fortrinnsvis er den såkalte senterløse eller aksellese skrue. Although both mixing devices 4 and 13 are shown equipped with two screws, it should be noted that a satisfactory result can often be achieved with only one mixing screw, which is preferably the so-called centerless or axleless screw.
Blandeanordningene 4 og 13 er fortrinnsvis stilt på skrå for å løfte utløpet høyere opp, hvilket muliggjør en høyere stabel . The mixing devices 4 and 13 are preferably set at an angle to lift the outlet higher up, which enables a higher stack.
Mateanardningene IQ og 15 i beholderne 9 og 14 omfatter fortrinnsvis hjelpeskruer 10a og 15a for å hindre hvelvdannelse og klebning av materialet til veggene i beholderne og for å frembringe en jevnere og lett innstillbar matning til den tverrgående skrue 11. The feeding devices IQ and 15 in the containers 9 and 14 preferably comprise auxiliary screws 10a and 15a to prevent vaulting and sticking of the material to the walls of the containers and to produce a more uniform and easily adjustable feed to the transverse screw 11.
Anordningen ifølge oppfinnelsen får sin drivkraft enten fra et slepekjøretøy, f.eks. en traktor, idet en separat skuffe-laster er nødvendig, eller fortrinnsvis fra sin egen kraft enhet som driv/es f.eks. au en f orbrenningsmotor, hvorved den slepende traktor kan fungere som en lasteanordning. The device according to the invention gets its driving force either from a towing vehicle, e.g. a tractor, as a separate bucket loader is necessary, or preferably from its own power unit that drives e.g. au an internal combustion engine, whereby the towing tractor can act as a loading device.
Mateanordningene og blandeanordningene er fortrinnsvis samtlige hydraulisk drevet og ved sammenkobling av drivanord-ningene både for mateanordningene la og 5a og for mateanordningene 10 og 15 kan sammensetningen av jordforbédringsmidlet hensiktsmessig varieres. Hastighetene for de tverrgående skruer, 2 og 6 samt for blandeskruene 4a, 4b og 13a, 14b er likeledes variable. Når anordningen er forsynt med en kraftenhet, kan én hydraulisk motor kobles til slepevognens 8, 17 hjul, hvorved anordningen automatisk kan forflytte seg i retning mot stabelen eller haugen. Til forflytning over lengere strekninger er anordningen ved hjelp av et ledd 18 festet til et slepende kjøretøy. The feeding devices and the mixing devices are preferably all hydraulically driven and by connecting the drive devices both for the feeding devices 1a and 5a and for the feeding devices 10 and 15, the composition of the soil improver can be appropriately varied. The speeds for the transverse screws, 2 and 6 as well as for the mixing screws 4a, 4b and 13a, 14b are likewise variable. When the device is provided with a power unit, one hydraulic motor can be connected to the trailer's 8, 17 wheels, whereby the device can automatically move in the direction of the stack or pile. For movement over longer distances, the device is attached to a towing vehicle by means of a link 18.
For enkelthets skyld er den ovennevnte hydrauliske anordning, kraftenhet og forskjellige koblingsanordninger utelatt fra tegningene. For the sake of simplicity, the above-mentioned hydraulic device, power unit and various coupling devices are omitted from the drawings.
