Description
Fremgangsmåte til oppberedning av metallavfall og slagg fra ikke-jernmetaller. Procedure for the preparation of metal waste and slag from non-ferrous metals.
Ved oppberedning av metallavfall fra When processing metal waste from
ikke-jernmetaller er det først nødvendig non-ferrous metals are first required
å knuse og løsgjøre avfallet, for deretter to crush and loosen the waste, for then
å kunne skille ut mekanisk og uten an-vendelse av varme de ikke smeltbare deler, to be able to separate mechanically and without the use of heat the non-fusible parts,
såsom oksyder, aske, formsand og lignende, i noen tilfelle også jern. such as oxides, ash, molding sand and the like, in some cases also iron.
Til nevnte formål har man hittil brukt For the aforementioned purpose, it has been used up to now
våte eller tørre kollerganger, eller rote-rende tromler, og også kulemøller. Avfallet har ofte måttet utsettes for timelang wet or dry colliers, or rotating drums, and also ball mills. The waste has often had to be left for hours
behandling av nevnte art. Ofte, og særlig processing of the said species. Often, and especially
ved behandling i kollerganger, er det påkrevet at der utføres en rekke atskilte ope-rasjoner som foregår i særlige innretnin-ger som igjen lider av den ulempe at de in the case of treatment in corridors, it is required that a number of separate operations are carried out which take place in special facilities which again suffer from the disadvantage that they
må fylles og tømmes, slik at en kontinuerlig drift ikke er mulig, hvorved også den must be filled and emptied, so that continuous operation is not possible, whereby also it
gjennomsnittlige ytelse blir forholdsvis average performance will be comparatively
mindre. Hensikten med oppfinnelsen er å less. The purpose of the invention is to
tilveiebringe en fremgangsmåte til oppberedning av metallavfall fra ikke-jernmetaller, ved hvilken metallavfallet skilles provide a method for the preparation of metal waste from non-ferrous metals, in which the metal waste is separated
kontinuerlig og automatisk i smeltbare og continuously and automatically in fusible and
ikke smeltbare materialer, samtidig som non-fusible materials, at the same time as
også jerndeler skilles ut for seg, og hvor iron parts are also separated separately, and where
hele prosessen foregår fullstendig støv-fritt. the entire process takes place completely dust-free.
Oppgaven kan bare løses hvis det istedenfor en kollergang eller kulemølle til The task can only be solved if instead of a collier gang or ball mill
knusing og oppluking av avfallet anvendes crushing and picking up the waste is used
en maskin som kan arbeide kontinuerlig, a machine that can work continuously,
f. eks. en støtmølle, hammermølle, slag-mølle eller lignende, av den art som brukes e.g. an impact mill, hammer mill, impact mill or the like, of the type used
til knusing av stein, kull eller annet bryt-bart materiale. for crushing stone, coal or other breakable material.
Møller av nevnte art skulle tilsynela-tende ikke egne seg til knusing og løsgjø- Mills of the aforementioned type would apparently not be suitable for crushing and loosening
relse av metallavfallet, da dette tildels inneholder massive, metallholdige klum-per som ikke lar seg sønderdele ytterligere. Det har imidlertid vist seg at slike støt-eller slagmøller bearbeider avfallsklum-pene på en slik måte at de sjikt som inneholder lite eller intet metall faller fra i en slik utstrekning at resten kan smeltes inn på en rasjonell måte. disposal of the metal waste, as this partly contains massive, metal-containing lumps that cannot be broken down further. However, it has been shown that such impact or impact mills process the waste lumps in such a way that the layers containing little or no metal fall off to such an extent that the rest can be melted in in a rational way.
Ved bruk av en slagmølle istedenfor kollergangen formales ikke metallet mere enn påkrevet, slik at unødig tap av metall unngåes. When using an impact mill instead of the collier, the metal is not ground more than required, so that unnecessary loss of metal is avoided.
Fremgangsmåten i henhold til oppfinnelsen utmerker seg ved at der til å knuse og løsgjøre avfallet benyttes en slagmølle som støter det så behandlede materialav-fall ut på et såld eller en vibrasjonsrenne som skiller ut partikler med kornstørrelse på ca. 1 mm og mindre, hvorved de grovere partikler eller stykker over en transportør føres direkte til en samlekasse, mens de utskilte partikler med kornstørrelse inn-til ca. 1 mm føres i sugestrøm til en sikt-innretning for utskillelse av partikler med kornstørrelse 0,2—1 mm, hvoretter resten av materialene i en cyklon enda en gang skilles etter kornstørrelse på ca. 0,05—2 mm og mindre, mens støvet, dvs. partikler mindre enn 0,05 mm oppfanges i et finfilter. The method according to the invention is distinguished by the fact that an impact mill is used to crush and loosen the waste, which pushes the material waste treated in this way onto a sieve or a vibrating chute which separates out particles with a grain size of approx. 1 mm and smaller, whereby the coarser particles or pieces are taken over a conveyor directly to a collection box, while the separated particles with a grain size of up to approx. 1 mm is fed in a suction stream to a sieve device for separating particles with a grain size of 0.2-1 mm, after which the rest of the materials are separated in a cyclone once again according to a grain size of approx. 0.05—2 mm and smaller, while the dust, i.e. particles smaller than 0.05 mm, is collected in a fine filter.
Oppfinnelsen skal forklares ved hjelp av et eksempel under henvisning til teg-ningene, hvor fig. 1 er et oppriss, fig. 2 et sideriss, og fig. 3 et grunnriss av et anlegg til utførelse av fremgangsmåten i henhold til oppfinnelsen. The invention shall be explained by means of an example with reference to the drawings, where fig. 1 is an elevation, fig. 2 a side view, and fig. 3 a floor plan of a plant for carrying out the method according to the invention.
Rått, ikke behandlet metallholdig av-fall føres- til et. transportbånd 3 som delvis er nedsenket i gulvet, og leveres av dette til en. støt- eller slagmølle 5 som drives fra en motor 6. Slagmøllehuset er forbun-det med en sugeledning 7 som tjener til' bortledning av støv. Møllens utløpstrakt 5a1 munner ut over et på skrå anordnet etasje-såld som eksempelvis består av to såld'-plater som er anordnet over hinannen. Den øvre såldplate 8 er forsynt med hull med ca. 6 mm diameter og den nedre såldplate 9' har siktehull' med 1 mm diameter. Raw, untreated metal-containing waste is taken to a conveyor belt 3 which is partially submerged in the floor, and is delivered by this to a. impact or impact mill 5 which is driven from a motor 6. The impact mill housing is connected to a suction line 7 which serves to remove dust. The mill's outlet funnel 5a1 opens onto an obliquely arranged floor sieve which, for example, consists of two sieve plates which are arranged one above the other. The upper sieve plate 8 is provided with holes with approx. 6 mm diameter and the lower sieve plate 9' has sight holes' with a 1 mm diameter.
Det øvre' såld 8 tjener bare til be-skyttelse' av det nedre1 såld 9: De grovere partikler eller stykker som faller gjennom det øvre såld. bevirker at det nedre såld1 ikke tilstoppes. Alle partikler eller stykker som er større enn 1 mm faller på et transportbånd 10, passerer over en øvre båndtrommel 12 som< er utformet som. en: magnet, og faller over en fordelingsrenne 15 direkte i en transportbeholder 13. De bestanddeler som tiltrekkes av magneten, kastes1 i en beholder 14. Såldene 8 og 9 kan erstattes- med<1> en ett- eller flertrinnsvibra-sjonsrenne-. Materialet med- kornstørrelse.' ca. 1 mm og mindre kan suges- ut direkte-ved- trinnovergangene ved hjelp av- luft-strøm-. The upper screen 8 only serves to protect the lower screen 9: The coarser particles or pieces that fall through the upper screen. causes the lower sieve1 not to become clogged. All particles or pieces larger than 1 mm fall onto a conveyor belt 10, passing over an upper belt drum 12 which is designed as a: magnet, and falls over a distribution chute 15 directly into a transport container 13. The components that are attracted by the magnet are thrown1 into a container 14. The sieves 8 and 9 can be replaced- with <1> a one- or multi-stage vibration chute-. The material with- grain size.' about. 1 mm and less can be sucked out directly at the step transitions using air flow.
Det materiale'som' faller gjennom sikten. 9" med' 1 mm hull er en blanding av metaller, aske, sand!, oksyder osv. Blandin-gen-føres-gjennom en sugeledning 7a, fig. 3 tir en sikteinnretning 1-6. Her skilles de partikler ut som1 er større enn 0,2 mm, mens alle andre partikler, også de med mindre spesifikk vekt, føres videre i en luftstrøm1' som; frembringes av en vifte 24'. Alle bestanddeler som er større enn. 0,2' mm, føres- ut av sikten gjennom en utløps-sluse1 16a (som sperret for luftstrømmen)' og opp på to etter hinannen anordnede trommelmagneter 18 som er anbragt i. et magnethus 17. Ikke magnetiske partikler jf aller ned i en beholder 19, mens jern- og jernholdige partikler faller i en annen beholder 20. Det i beholderen 19 oppsamlede met'allgrus: kan da smeltes igjen. The material 'that' falls through the sieve. 9" with a 1 mm hole is a mixture of metals, ash, sand, oxides, etc. The mixture is passed through a suction line 7a, fig. 3 and a screening device 1-6. Here, the particles that are larger are separated out than 0.2 mm, while all other particles, even those with a smaller specific weight, are carried on in an air stream 1' which is produced by a fan 24'. All components larger than 0.2' mm are carried out by the sieve through an outlet sluice 1 16a (which blocked the air flow)' and onto two drum magnets 18 arranged one behind the other, which are placed in a magnet housing 17. Non-magnetic particles cf further down into a container 19, while ferrous and ferrous particles fall in another container 20. The metallic gravel collected in the container 19 can then be melted again.
Det i luftstrømmen fra sikten bortsu-,gede materiale føres gjennom en syklon 21, Ihvori korn med størrelse ca. 0,05—0,2 mm skilles ut. Det finstøv som blir igjen, skilles ut i et støvfilter 23 og støvfri luft strøm-mer ut av anordningen. Støvet fra syklo-nen og støv-frlteret er praktisk- talt me-tallf-ritt og kan anvendes- til andre formål-. The material sucked away in the air stream from the sieve is passed through a cyclone 21, in which grains with a size of approx. 0.05-0.2 mm is separated. The fine dust that remains is separated in a dust filter 23 and dust-free air flows out of the device. The dust from the cyclone and the dust filter is practically metal-free and can be used for other purposes.
