Opfindelsen angår en fremgangsmåde til filtrering af en suspension eller emulsion samt et apparat til udøvelse af fremgangsmåden.The invention relates to a method for filtering a suspension or emulsion and an apparatus for carrying out the process.
Det er kendt til filtrering af en suspension eller emulsion at tilføre denne til et lag partikelformet eller granuleret filtreringsmateriale i en tank eller beholder i et filtreringsapparat og at lade suspensionen strømme op gennem dette lag samt på egnet måde lade den ved filtreringen opnåede filtrerede væskefase afgå fra filtreringsmaterialelaget gennem udløb, der er udstyret med organer, f.eks. en jalousivæg eller en si til at hindre, at filtreringsmaterialet kan strømme ud sammen med den filtrerede væskefase.It is known to filter a suspension or emulsion to add it to a layer of particulate or granulated filtration material in a tank or container in a filtration apparatus and to allow the suspension to flow through this layer and suitably leave off the filtered liquid phase obtained by filtration. the filtration material layer through outlets equipped with means, e.g. a shutter wall or screen to prevent the filtration material from flowing out with the filtered liquid phase.

Det er ved et sådant filtreringsapparat kendt til opnåelse af et kontinuerligt arbejdende apparat, uden standsning af filtreringen ved rengøring af filtreringsmaterialet, at lade filtreringsmaterialet strømme nedad gennem filtreringstanken under filtreringen, at udtage det ved filtreringen forurenede filtreringsmateriale ved tankens bund til en ved siden af tanken anbragt rørledning, at lade det forurenede filtreringsmateriale passere gennem en vaskeafdeling samt derfra at føre det vaskede filtreringsmateriale tilbage til oversiden af filtreringsmaterialelaget i tanken. Ved et andet kendt filtreringsapparat, ligeledes med en ved siden af filtreringstanken anbragt vaskeafdeling men uden filtrering ved strømning i modstrøm mellem filtreringsmaterialet og suspensionen, sker vaskningen af filtreringsmaterialet under dettes strømning i modstrøm mod den anvendte vaskevæske, der udtages fra tilløbsledningen for suspension eller lignende, der skal filtreres.It is known in such a filtration apparatus to obtain a continuously operating apparatus, without stopping the filtration by cleaning the filtration material, to allow the filtration material to flow downwards through the filtration tank during filtration, to remove the filtration material contaminated by the filtration at the bottom of the tank. positioned pipeline, to allow the contaminated filtration material to pass through a wash section and from there to return the washed filtration material to the top of the filtration material layer in the tank. In another known filtration apparatus, also with a washing section located next to the filtration tank but without filtration by countercurrent flow between the filtration material and the suspension, the filtration material is washed under its countercurrent flow against the used washing liquid withdrawn from the inlet line for suspension or the like. that must be filtered.
Nærværende opfindelse har til formål at anvise et kontinuerligt arbejdende filtreringsapparat, som . foruden at bibeholde fordelen ved effektiv udnyttelse af filtreringsmaterialelaget ved den i og for sig kendte modstrømning mellem filtreringsmateriale og suspension under filtreringen og fordelen ved forbedret vaskning af filtreringsmaterialet ved den ligeledes, men i anden filtreringssammenhæng i og for sig kendte modstrømning mellem filtreringsmaterialet og vaskevæsken - med enkle midler og med pålidelig funktion giver højere kapacitet i forhold til nødvendige pladsforhold, som til stadighed udviser i hovedsagen samme filtreringsevne og samtidig sikrer øget effektivitet ved vaskningen af filtreringsmaterialet.The present invention has for its object to provide a continuously operating filtration apparatus which. in addition to maintaining the advantage of efficient utilization of the filtration material layer by the known flow of filtration material and suspension during filtration and the advantage of improved washing of the filtration material by the same, but in other filtration contexts in the known flow between the filtration material and the washing liquid - with simple means and with reliable function provide higher capacity in relation to required space conditions, which constantly exhibit essentially the same filtration ability and at the same time ensure increased efficiency in the washing of the filtration material.
Opfindelsen angår således en fremgangsmåde til i et filtreringsapparat at filtrere en suspension eller emulsion, der tilføres et lag granuleret eller partikelformet filtreringsmateriale, for under filtreringen at strømme opad gennem og afgå fra dette lag som filtreret væskefase, samt hvor filtreringsmaterialet under filtreringen strømmer nedad gennem laget i modstrøm mod suspensionen, forbi denne tilførsel og derefter transporteres adskilt fra filtreringsmaterialet til en afdeling for vaskning af ved filtrerin- 3 148525 gen forurenet filtreringsmateriale ved strømning i modstrøm mod en vaskevæske, hvorefter det vaskede filtreringsmateriale føres tilbage til oversiden af filtreringsmaterialelaget.The invention thus relates to a method of filtering in a filtration apparatus a suspension or emulsion applied to a layer of granulated or particulate filtration material, to flow upwardly and exit from this layer as a filtered liquid phase, and the filtration material during filtration flowing downwardly through the layer. in countercurrent to the suspension, past this inflow, and then separately transported from the filtration material to a filtering washable contaminant washing section by countercurrent flow to a wash liquid, after which the washed filtration material is returned to the top of the filtration material layer.
Denne fremgangsmåde er ifølge opfindelsen ejendommelig ved, at i hvert fald en del af den filtrerede væskefase afgår fra filtreringsmaterialelaget til opretholdelse af en over dette beliggende zone af filtreret væskefase, at den fra filtreringsmaterialelaget adskilte transport af forurenet filtreringsmateriale sker opad gennem den zone, hvori filtreringsmaterialelaget findes, og at vaskningen i vaskeafdelingen af forurenet filtreringsmateriale sker ved dettes strømning i modstrøm mod som vaskevæske udnyttet filtreret væskefase, der tilføres vaskeafdelingen fra zonen af filtreret væskefase.According to the invention, this process is characterized in that at least part of the filtered liquid phase departs from the filtration material layer to maintain a filtered liquid phase overlying this zone, that the transport of contaminated filtration material separated from the filtration material layer takes place upwards through the zone in which the filtration material layer is found and that the washing in the washing section of contaminated filtration material is effected by its countercurrent flow against the filtered liquid phase used as a washing liquid, which is fed to the washing section from the filtered liquid phase zone.
Hele filtreringen og hele vaskningen kan herved ske inden i fil-treringsapparatet, og som vaskevæske udnyttes på enkel og fordelagtig måde den ved filtreringen opnåede væskefase.The entire filtration and the entire washing can thereby be carried out within the filtration apparatus, and as washing liquid is utilized in a simple and advantageous manner the liquid phase obtained by the filtration.
Inden for rammerne af fremgangsmåden ifølge opfindelsen er det muligt, som det fremgår af efterfølgende patentkrav, at opnå yderligere forbedringer med hensyn til effektivisering af såvel vaskningen som filtreringen.Within the scope of the process according to the invention, it is possible, as will become apparent from the following claims, further improvements in efficiency of both washing and filtration.
Således kan, jvf. krav 2 mængden af vaskevæske reguleres ved ændring af niveauet for zonen af filtreret væskefase, medens mængden • af til vaskeafdelingen transporteret filtreringsmateriale ifølge krav 3 reguleres ved mængdeafføling eller trykafføling af suspensionen før dennes tilførsel til filtreringsmaterialelaget.Thus, according to claim 2, the amount of wash liquid can be regulated by changing the level of the filtered liquid phase zone, while the amount of filtration material transported to the wash compartment according to claim 3 is regulated by quantity sensing or pressure sensing the suspension prior to its application to the filtration material layer.
Opfindelsen angår tillige et filtreringsapparat til udøvelse af fremgangsmåden ifølge opfindelsen, og som omfatter en lodret zone med et lag af partikelformet eller granuleret filtreringsmateriale, et indløb for den suspension eller emulsion, der skal filtreres, og som er således beliggende i forhold til filtreringsmaterialelaget, at suspensionen under filtreringen bringes til at strømme opad gennem filtreringsmaterialelaget, et under indløbet 4 148525 beliggende og frit i forbindelse med filtreringsmaterialelagets zone stående rum, hvortil filtreringsmateriale tilføres kontinuer— ligt ved strømning nedad gennem filtreringsmaterialélaget, og et i rummet .udmundende transportaggregat til at transportere det til rummet, tilførte, ved filtreringen forurenede filtreringsmateriale til -én vaskeafdeling, der er indrettet til vaskning af filtreringsmaterialet ved dettes strømning i modstrøm mod en vaskevæske, og i hvorfra det. vaskede filtreringsmateriale føres tilbage til filtre ringsmaterialelagets overside. Dette apparat er ifølge opfindelsen ejendommelig ved, at det yderligere er udformet således, at der - over filtreringsmaterialelaget er opretholdt én zone af ved fil treringen opnået filtreret væskefase, at transportaggregatet består af et rør, som fra det nævnte rum strækker sig op gennem fil-treringsmaterialelaget til zonen af filtreret væskefase og er tilsluttet vaskeafdelingens øvre del, og at vaskeafdelingens nedre del er forsynet med mindst ét til zonen af filtreret væskefase sluttet indløb beliggende under denne zones overflade.The invention also relates to a filtration apparatus for carrying out the method according to the invention, which comprises a vertical zone with a layer of particulate or granulated filtration material, an inlet for the suspension or emulsion to be filtered and thus situated relative to the filtration material layer. the suspension during filtration is caused to flow upwardly through the filtration material layer, a space located freely adjacent to the zone of the filtration material layer, to which filtration material is continuously supplied by flow downwards through the filtration material layer, and an inlet chamber which transports it. to the compartment, filtration material contaminated by the filtration was added to a washing compartment adapted to wash the filtration material by its countercurrent flow to a washing liquid and into it. washed filtration material is returned to the top of the filter material layer. According to the invention, this apparatus is further characterized in that it is further designed such that - one zone of the filtered liquid phase obtained by filtration is maintained over the filtration material layer, that the conveyor assembly consists of a pipe extending from said space through the filter chamber. the filtration material layer to the filtered liquid phase zone and is connected to the upper portion of the wash compartment and the lower portion of the wash compartment is provided with at least one inlet of the filtered liquid phase inlet located below the surface of this zone.
Yderligere ejendommelige træk og yderligere fordele ved opfindelsen vil fremgå af patentkravene og af den efterfølgende beskrivelse af et eksempel på udformningen af et filtreringsapparat i-følge opfindelsen med henvisning til tegningen, hvor fig. 1 viser filtreringsapparatet i lodret snit, fig. 2 er et lodret snit i større målestok af apparatets øvre del for tydeligere at vise den i apparatet indgående vaskeafdeling, og fig. 3 viser skematisk set fra oven et antal til et filtreringsanlæg sammenbyggede filtreringsapparater ifølge opfindelsen.Further peculiar features and additional advantages of the invention will become apparent from the claims and from the following description of an example of the design of a filtration apparatus according to the invention with reference to the drawing, in which fig. 1 shows the filtration apparatus in vertical section; FIG. 2 is a larger scale vertical section of the upper portion of the apparatus to more clearly show the wash section included in the apparatus; and FIG. 3 is a schematic top view of a plurality of filtration apparatus incorporated into a filtration system according to the invention.
I den i fig. 1 viste udførelsesform for et apparat ifølge opfindelsen er et lag granuleret eller partikelformet filtreringsmateriale 1 anbragt i en beholder med sidevægge 2 og en konus- eller pyramideformet bund 3 med nedad vendende spids. Konusens eller pyra- 5 148525 midens basis bør fortrinsvis svare til beholderens af sidevæggene bestemte form.In the embodiment shown in FIG. 1 for an apparatus according to the invention, a layer of granulated or particulate filtration material 1 is placed in a container with side walls 2 and a cone or pyramid shaped bottom 3 with a downward point. The base of the cone or pyramid should preferably correspond to the shape of the container defined by the side walls.
Det granulerede filtreringsmateriale kan hensigtsmæssigt være sand, men også andre materialer f.eks. plast eller blandinger af flere materialer kan anvendes. En blanding af sådant materiale med flere kornstørrelser kan i modsætning til den hidtil kendte teknik anvendes i et kontinuerligt arbejdende apparat ifølge opfindelsen, dog afhængigt af hvad der skal filtreres, og hvor effektivt filtreringen skal udføres. En fagmand vil i hvert enkelt tilfælde kunne finde det bedst egnede materiale og den bedst egnede kornstørrelse.The granulated filtration material may conveniently be true, but also other materials e.g. plastics or mixtures of multiple materials may be used. A mixture of such multi-grain material can, unlike the prior art, be used in a continuously operating apparatus according to the invention, however, depending on what is to be filtered and how efficiently the filtration is to be carried out. A person skilled in the art will be able to find the most suitable material and the most suitable grain size in each case.
Den suspension eller emulsion, der skal filtreres, tilføres som vist med pilen A til beholderen gennem et indløb 4, fortrinsvis i beholderens bund. Indstrømningen af suspensionen i filtreringsmaterialet sker i materialelagets nederste del gennem et antal rør 5, og over-hvert af disse rørs munding 6 er anbragt et vinkeltag 7, der hindrer, at filtreringsmaterialet kommer i direkte kontakt med rørmundingen, og som udsætter den tilstrømmende suspension for en større flade filtreringsmateriale, således at risikoen for tilstopning af filteret på grund af kraftig momentan tilsmudsning af filtreringsmaterialet ved rørmundingeme formindskes. Som følge af rørmundingerne s anbringelse med overliggende tag, og som følge af tagenes vinkelform, opstår der mindst mulig hindring for filtreringsmaterialets bevægelse nedad. Anbringelsen af rørmundingerne 6 i filtreringsmaterialets nederste del har den fordel, at den mest tilsmudsede del af filtreringsmaterialet, d.v.s. den del der passerer forbi tagene og rørmundingerne, fortsætter nedad, således at det ikke længere udnyttes til filtrering. Herved hindres tilstopning af mundingerne, og den tilstrømmende suspension møder stadig nyt filtreringsmateriale, når den strømmer i modstrøm mod filtreringsmaterialet opad gennem dette mod stadig renere materiale. Den ved suspensionens strømning opad gennem laget af filtreringsmateriale opnåede filtrerede væskefase opretholdes som en zone 8 af filtreret væskefase over laget af filtreringsmateriale, og dens niveau er i det viste eksempel fastlagt ved, at den filtrerede væskefase udtages fra apparatet gennem et overløb 9 til et afløb som vist med pilen B.The suspension or emulsion to be filtered is applied as indicated by arrow A to the container through an inlet 4, preferably in the bottom of the container. The suspension of the suspension into the filtration material takes place in the lower part of the material layer through a plurality of tubes 5, and over each of the mouths of these tubes 6 is provided an angular roof 7 which prevents the filtration material from coming into direct contact with the orifice and exposing the flowing suspension to the a larger flat filtration material so that the risk of clogging the filter due to excessive instantaneous soiling of the filtration material at the pipe mouths is reduced. As a result of the arrangement of the pipe mouths with the overlying roof, and because of the angular shape of the roofs, the least possible obstacle to the downward movement of the filtration material arises. The placement of the orifices 6 in the lower part of the filtration material has the advantage that the most soiled part of the filtration material, i.e. the part which passes past the roofs and the orifices continues downward so that it is no longer utilized for filtration. This prevents clogging of the orifices and the inflowing suspension still encounters new filtration material as it flows countercurrently against the filtration material upwardly through it towards ever cleaner material. The filtered liquid phase obtained by flowing upwards through the suspension through the filtered material layer is maintained as a zone 8 of filtered liquid phase over the filter material layer and its level is determined in the example shown by withdrawing the filtered liquid phase from the apparatus through an overflow 9 to a drain. as shown by the arrow B.
6 148525 I beholderens nedre konus- eller pyramideformede bund 3, som det ved filtreringen tilsmudsede filtreringsmateriale strømmer ned i, er anbragt den nederste ende af et egnet transportaggregat 10, der strækker sig op gennem midten af apparatet, og somf.eks. består af en mammutpumpe. En sådan pumpe arbejder med luft som transportmedium, og luften tilføres oppefra og strømmer ned gennem en ledning 11, der strækker-sig langs med et transportrør 12, der er en del af transportaggregatet 10. Luften tilføres transportrøret 12 gennem ikke viste huller i ledningens 11 nederste ende, og filtreringsmaterialet transporteres som vist med pilen C af luften gennem røret 12 op til en over laget af filtreringsmateriale anbragt vaskeafdeling 13, der omtales nærmere nedenfor.In the lower cone or pyramid-shaped bottom 3 of the container, into which the filtration material soiled by filtration flows, is placed the lower end of a suitable transport assembly 10 extending through the center of the apparatus, and e.g. consists of a mammoth pump. Such a pump operates with air as a transport medium, and the air is supplied from above and flows down through a conduit 11 extending along a conveyor tube 12 which is part of the conveyor assembly 10. The air is supplied to the conduit 12 through holes not shown in the conduit 11. the bottom end and the filtration material is conveyed as indicated by arrow C of the air through the pipe 12 up to a wash section 13 disposed over the layer of filtration material, which is discussed further below.
Hvis luften, der ledes ind i mammutpumpen, af en eller anden grund skulle trænge ud gennem transportrørets 12 nedre del og ind i fil-. treringsmaterialet, vil der være risiko for, at filtreringsmaterialet fluidiseres stedvis, hvilket vil kunne bevirke en betydelig forringelse af apparatets filtreringsevne. For at hindre dette er der omkring mammutpumpen over dennes nederste ende anbragt en tragt - 14, hvis tilspidsede ende vender, opad, og som er indrettet.til at opfange luft, der måtte fremkomme fra transportrøréts nedre ende, . og at aflede sådan luft gennem huller i tragtens smalle ende til en ledning 15, der strækker sig langs transportrøret 12. Tragten 14 tjener tillige som ledeorgan for filtreringsmaterialets strømning, således at der opnås et ensartet, jævnt strømningsmønster over ap-paratets tværsnit..If for some reason the air entering the mammoth pump should penetrate through the lower portion of the conveyor tube 12 and into the filing chamber. the filtration material, there will be a risk that the filtration material will be fluidized in place, which could cause a significant deterioration of the filtration capacity of the apparatus. To prevent this, a funnel - 14, whose tapered end faces upwardly and is arranged around the mammoth pump above its lower end, is arranged to trap air which may emerge from the lower end of the conveyor pipe,. and diverting such air through holes at the narrow end of the hopper to a conduit 15 extending along the conveying pipe 12. The hopper 14 also serves as a guide for the flow of the filtration material so that a uniform, uniform flow pattern is obtained across the cross-section of the apparatus.
De foran omtalte tage 7 over rørmundingerne 6 bidrager ligesom tragten 14 til, at man opnår et ønsket'strømningsmønster. Sådanne tage kan, skønt det ikke er vist, med henblik på yderligere at sikre det ønskede strømningsmønster, findes i laget af filtreringsmateriale på andre passende steder, uden at være kombineret med indstrømningsrør for suspensionen.The above mentioned roofs 7 over the pipe mouths 6, like the funnel 14, contribute to achieving a desired flow pattern. Such roofs, although not shown, to further assure the desired flow pattern, can be found in the layer of filtration material at other suitable locations, without being combined with the suspension inlet pipe.
Fig. 2 viser i større målestok afdelingen 13 til vaskning af tilsmudset filtreringsmateriale, der strømmer ud af transportrørets 12 øverste ende, hvorfra det som vist med pilen D strømmer ned gennem et vaskerum, der er dannet mellem transportrøret 12 og 7 148525 en ydre kappe 16, der fortrinsvis er anbragt koncentrisk omkring transportrøret. Filtreringsmaterialet kan som følge af tilsmudsningen indeholde sammenhængende materialekager, der imidlertid vil blive knust ved at støde mod en i filtreringsmaterialets strømningsbane anbragt skærm 17 eller lignende, samtidig med at filtreringsmaterialets faldhastighed bremses. Filtreringsmaterialet møder derefter længere nede i vaskerummet en mellembund 18, der er udformet med huller 19, og som fortrinsvis efterfølges af et antal tilsvarende mellembunde. I det viste eksempel findes fem sådanne mellembunde. Hullerne 19 i to efter hinanden følgende mellembunde er fortrinsvis forskudt således i forhold til hinanden, at de ikke danner en fri, lodret passage for filtreringsmaterialet. I vaskeafdelingen møder filtreringsmaterialet stadig vaskevæske i modstrøm, og ved hullerne 19 i mellembundene 18 bliver vaskevæskens hastighed momentant større, hvorved der opstår særligt gunstige betingelser for vaskning af filtreringsmaterialet.FIG. 2 shows, on a larger scale, the section 13 for washing dirty filtration material flowing out of the upper end of the transport tube 12, from which, as shown by arrow D, it flows down through a wash space formed between the transport tube 12 and 7 an outer jacket 16 which is preferably located concentrically around the transport tube. As a result of the soiling, the filtration material may contain coherent material cakes which, however, will be crushed by impinging on a screen 17 or the like located in the flow path of the filtration material, while slowing down the rate of filtration material. The filtration material then encounters further down in the laundry room an intermediate bottom 18 formed with holes 19, which is preferably followed by a number of corresponding intermediate bottoms. In the example shown there are five such intermediate bottoms. The holes 19 in two successive intermediate bottoms are preferably offset so as not to form a free vertical passage for the filtration material. In the wash section, the filtration material still encounters wash liquid in countercurrent, and at the holes 19 in the intermediate bottoms 18 the velocity of the wash liquid is momentarily increased, thereby creating particularly favorable conditions for washing the filtration material.
Som vaskevæske anvendes den filtrerede væskefase i zonen 8 over filtreringsmaterialelaget, idet vaskeafdelingen 13 er nedsænket i denne zone, og som vist med pilen E indføres vaskevæsken i vaskerummet gennem den mellem kappens 16 nedre ende og transportrøret 12 dannede åbning 20 og strømmer opad gennem vaskerummet. Den ved vask-ningen forurenede væske bortledes fra vaskerummet som vist med pilen F og føres over et overløb 21 ud af apparatet som vist med pilen G. Dette overløb 21 kan være justerbart i højden og/eller i bredden til regulering af væskemængden. Når overløbet sænkes, øges mængden af vaskevæske, der ligeledes øges automatisk, når niveauet over filtreringsmaterialelaget stiger f.eks. ved øget belastning af filtreringsapparatet.As the wash liquid, the filtered liquid phase in zone 8 is used above the filtration material layer, the wash compartment 13 being submerged in this zone, and as shown by arrow E, the wash liquid is introduced into the wash space through the opening 20 formed between the lower end of the jacket 16 and the conveyor tube 12 and flows upwardly through the wash space. The liquid contaminated by the wash is discharged from the washroom as shown by arrow F and is passed over an overflow 21 out of the apparatus as shown by arrow G. This overflow 21 may be adjustable in height and / or in width to control the amount of liquid. As the overflow is lowered, the amount of washing liquid which is also automatically increased as the level above the filtration material layer increases e.g. by increasing the load of the filtration apparatus.
Til at lede det fra transportrøret 12 kommende filtreringsmateriale nedad til vaskerummet og til at adskille det forurenede filtreringsmateriale fra det indkommende filtreringsmateriale er et rør 22 anbragt mellem kappen 16 og transportrøret 12 og ført et stykke forbi transportrørets øvre ende. Røret 22 strækker sig op gennem kappen 16, og lufttilførselsledningen 11 og luftafledningsrøret 15 er ført gennem røret 22, der endvidere indeholder 8 148525 organer 23 til opfangning af luft med filtreringsmateriale fra ..transportrøret 12. I det viste eksempel består disse organer 23 af.skiftevis anbragte nedad vendende kegleformede og opad vendende keglestubformede organer.To guide the filtration material coming from the conveyor pipe 12 down to the laundry room and to separate the contaminated filtration material from the incoming filtration material, a pipe 22 is arranged between the casing 16 and the conveyor pipe 12 and passed a distance past the upper end of the conveyor pipe. The pipe 22 extends through the casing 16, and the air supply line 11 and the air discharge pipe 15 are passed through the pipe 22, which further contains means 23 for trapping air with filtration material from the conveyor pipe 12. In the example shown, these means 23 consist of. alternately disposed downwardly cone-shaped and upwardly cone-shaped members.
Skønt det ikke er vist, kan om ønsket en del af den ved filtreringen opnåede filtrerede væskefase udtages i laget af filtrerings-materiale tinder dettes overflade, idet der fortrinsvis tilnærmelsesvis lodret over tilførselsrørenes mundinger 6 anbringes udløbs-rør for filtreret væskefase, og.eventuelt tage svarende til tagene 7. Ved at udtage den filtrerede væskefase gennem sådanne udløbsrør, hvis mundinger ligger i filtreringsmaterialelaget, opnås der sik-- kerhed for en godt filtreret væskefase selv ved f.eks. driftsforstyrrelser i vaske afdelingen,- der kunne medføre forurening af væskefasen over laget af filtreringsmateriale.Although not shown, if desired, a portion of the filtered liquid phase obtained in the filtration can be taken out in the layer of filtration material, its surface being preferably disposed approximately vertically above the nozzles 6 of the feed pipes, and optionally taking corresponding to the roofs 7. By withdrawing the filtered liquid phase through such outlet pipes, the orifices of which are in the filtration material layer, assurance of a well-filtered liquid phase is achieved even by, for example, operating disruptions in the washing department, - which could cause contamination of the liquid phase over the layer of filtration material.
Under vaskeafdelingen er anbragt et konusformet organ 24 til at sprede filtr'eringsmateriale, der fremkommer fra vaskeafdelingen, ud over oversiden af laget af filtreringsmateriale, og med henblik på at dette materiale også spredes over den del af filtreringsmateriale-~ laget, der ligger lige under spredeorganet, er dette hensigtsmæssigt udformet med et antal huller 25, der er anbragt således, at materialet spredes jævnt.Below the wash compartment is provided a cone-shaped member 24 for spreading filtration material emerging from the wash compartment beyond the top of the filtration material layer, and so that this material is also spread over the portion of the filtration material layer just below the spreading means, this is conveniently formed with a plurality of holes 25 arranged so that the material is evenly spread.
Foruden den foran beskrevne automatiske regulering af vaskevæskemængden kan der, selv om det ikke er vist, også tilvejebringes automatisk regulering af mængden af filtreringsmateriale til vaskning.In addition to the automatic liquid volume control described above, although not shown, automatic control of the amount of filtration material for washing can also be provided.
Ved hjælp af en ved tilførselsledningen for suspensionen, der i fig. 1 er markeret med pilen A, anbragt mængdeføler eller en tryk-, føler, kan der gives signal vedrørende en indtruffet ændring, f.eks* trykforøgelse på grund af akkumulering af suspenderet materiale i filtreringsmaterialelaget, og dette signal kan på kendt måde bringes til at regulere transportaggregatets 10 kapacitet således, at den transporterede-mængde filtreringsmateriale til vaskning øges respektive mindskes.By means of a supply line for the suspension shown in FIG. 1 is marked with arrow A, applied to a quantity sensor or a pressure sensor, a signal may be given regarding a change that has occurred, for example * pressure increase due to accumulation of suspended material in the filtration material layer, and this signal can in a known manner be caused to adjusting the capacity of the transport unit 10 so that the amount of filtered material for washing is increased or decreased, respectively.
I det foran beskrevne og på tegningen viste udførelseseksempel på filtreringsapparatet ifølge opfindelsen er vaskeafdelingen nedsæn- 148525 9 ket i zonen 8 af filtreret væskefase, hvorfra filtreret væskefase indtages som vaskevæske gennem åbningen 20. Alternativt kan filtreret væskefase til vaskningen indtages fra siden gennem en eller flere åbninger i kappens 16 nedre del. I en anden ikke vist alternativ udførelsesform, hvor filtreret væskefase fra zonen 8 ligeledes udnyttes som vaskevæske, er i hvert fald en del af vaskeafdelingen nedsænket i og anbragt adskilt i forhold til filtreringsmaterialelaget, hvorhos en eller flere ledninger er trukket fra zonen 8 til vaskeafdelingens nedre del for tilførsel af vaskevæske til den således beliggende vaskeafdeling.In the exemplary embodiment of the filtration apparatus according to the invention described above and in the drawing, the washing section is immersed in the zone 8 of filtered liquid phase, from which filtered liquid phase is taken as washing liquid through the opening 20. Alternatively, filtered liquid phase for the washing can be taken from the side through one or more openings in the lower part of the jacket 16. In another alternative embodiment not shown, in which filtered liquid phase from zone 8 is also utilized as washing liquid, at least part of the washing compartment is submerged in and placed separately from the filtration material layer, where one or more wires are drawn from zone 8 to the bottom of the wash compartment. part for supplying washing liquid to the washing section thus located.
Med et filtreringsapparat ifølge opfindelsen, f.eks. den i fig. 1 og 2 viste, foretrukne udførelsesform, muliggøres en udformning med forholdsvis små dimensioner, hvorved der opnås den fordel, at apparatet ikke bliver for uhåndterligt og vanskeligt at betjene.With a filtration apparatus according to the invention, e.g. FIG. 1 and 2, a relatively small design is made possible, thereby obtaining the advantage that the apparatus does not become too unmanageable and difficult to operate.
Som følge af at samtlige for det kontinuerligt arbejdende apparat nødvendige organer er beliggende inde i apparatet, og af at visse af apparatets dele f.eks. vaskeafdelingen og transportaggregatet kan være udformede som enheder, er apparatet velegnet til fremstilling som modul. Herved kan ved behov for større filtreringskapacitet, end hvad et enkelt apparat kan yde, på en enkel og fordelagtig måde flere apparater sammenbygges til et filtreringsanlæg. Et eksempel på et sådant anlæg er vist skematisk i fig. 3, der viser en gruppe på otte sammenkoblede, modulopbyggede filtreringsappara ter. I hvert modul indgår herved samtlige for de i fig. 1 og 2 viste apparater ifølge opfindelsen nødvendige organer, bortset fra at de mod hinanden i gruppen grænsende vægge 2 er borttaget, (de i fig. 3 viste stiplede linier illustrerer bunddelenes 3 øvre kant), hvorhos der for hver række 29 filtreringsapparater findes et fælles udløb 26 for den filtrerede væskefase, som afgår fra hvert filtreringsapparat (jfr. pilen B i fig. 1 og 2), og for begge rækker 29 findes et fælles udløb 27 for den ved vaskningen forurenede væske (jfr. pilen G i fig. 1 og 2). Disse fælles udløb 26 og/eller 27 behøver ikke at være anbragt som vist men forenkler opbygningen af filtreringsanlægget væsentligt. Anlæggets omsluttende ydervæg 28Due to the fact that all the means necessary for the continuously operating apparatus are located within the apparatus and that certain parts of the apparatus e.g. the washing compartment and the transport unit can be designed as units, the apparatus is well suited for manufacture as a module. As a result, when required for greater filtration capacity than a single appliance can provide, multiple appliances can be assembled in a simple and advantageous manner for a filtration plant. An example of such a plant is shown schematically in FIG. 3, showing a group of eight interconnected modular filtration devices. In each module, all of the components of FIG. 1 and 2 means according to the invention are necessary except that the adjacent walls 2 in the group are removed (the dotted lines illustrated in Fig. 3 illustrate the upper edge of the bottom parts 3), for which there is a common for each row of 29 filtration devices outlet 26 for the filtered liquid phase leaving from each filtration apparatus (cf. arrow B in Figs. 1 and 2), and for both rows 29 there is a common outlet 27 for the liquid contaminated by washing (cf. arrow G in Fig. 1). and 2). These common outlets 26 and / or 27 need not be disposed as shown but substantially simplify the construction of the filtration system. The enclosing outer wall of the plant 28
