Description

15 20 25 30 35 40 462 201 tyngre partiklar ur en vätska. _ Uppfinningen kommer närmare att beskrivas i form av ett exempel under hänvisning till ritningen, som schematiskt visar uppfinningen i snitt sedd från sidan. Heavier particles from a liquid. The invention will be described in more detail in the form of an example with reference to the drawing, which schematically shows the invention in section seen from the side.

I figuren betecknar 1 nedre delen av en separerings- kammare 1 av den typ, som visas och beskrivs i nämda svenska patent 8305717-4. Separeringskammaren 1 är ansluten till en vakuumkälla och försedd med en tilloppsöppning för tangentiell tillförsel av den förorenade vätskan, vilken skall filtreras.In the figure, 1 denotes the lower part of a separation chamber 1 of the type shown and described in said Swedish patent 8305717-4. The separation chamber 1 is connected to a vacuum source and provided with an inlet opening for tangential supply of the contaminated liquid, which is to be filtered.

Separeringskammarens 1 nedre del är trattformigt utformad och mynnar i en koniskt avsmalnande öppning 2, vilken övergår i en mynning i form av en utátvikt krage 3. Separeringskammaren 1 med öppningen 2 och kragen 3 utgör ej någon del av uppfinning- en utan hänvisas här till nämnda svenska patent.The lower part of the separating chamber 1 is funnel-shaped and opens into a conically tapered opening 2, which merges into an orifice in the form of an outwardly folded collar 3. The separating chamber 1 with the opening 2 and the collar 3 does not form part of the invention but reference is made here to the Swedish patent.

Separeringskammaren 1 är rotationssymmetrisk till form- en.The separation chamber 1 is rotationally symmetrical to the mold.

Filtret enligt uppfinningen består av ett cylindriskt hölje 4, vilket är tillslutet nedtill medelst en botten 5 men öppet upptill. I höljet 1 är ett mot dettas längd svarande rörparti 6 anordnat, vilket utefter en del av sin längd upp- visar skruvlinjeformiga flänsar eller vulster 7. Nedtill ansluter rörpartiet 6 till höljets 4 botten 5 via ett filter- organ 8. Flänsarnas 7 yttersta perifera delar ansluter mot höljesväggens insida. Inuti rörpartiet 6 och inom den axiella sträckningen för flänsarna 7 är en cylinderformad kanal 9 anordnad sä, att dess mantelyta ansluter till flänsarnas 7 inre perifera kanter. Som framgår av ritningen har den cylinderformade kanalen en längd sådan, att dess övre ände börjar nedanför den översta flänsen och slutar ovanför den nedersta flänsen. Dimensioneringen hos filtret är sådant, att separeringskammarens 1 krage 3 befinner sig straxt ovanför kanalens 9 övre ände.'Höljet 4 uppvisar vidare upptill ett breddavlopp 10 i form av en rörmynning, vilken via en ledning är ansluten till en sugpump P. Höljet 4 är upptill medelst exempelvis en bajonettfattning, antydd med 11, lösbart fast- satt i en försânkning hos separeringskammarens 1 nedre del.The filter according to the invention consists of a cylindrical housing 4, which is closed at the bottom by means of a bottom 5 but open at the top. In the housing 1 a pipe portion 6 corresponding to its length is arranged, which along a part of its length has helical flanges or beads 7. At the bottom the pipe portion 6 connects to the bottom 5 of the housing 4 via a filter member 8. The outermost peripheral parts of the flanges 7 connects to the inside of the housing wall. Inside the pipe portion 6 and within the axial extension of the flanges 7, a cylindrical channel 9 is arranged so that its circumferential surface connects to the inner peripheral edges of the flanges 7. As can be seen from the drawing, the cylindrical channel has a length such that its upper end begins below the upper flange and ends above the lower flange. The dimensioning of the filter is such that the collar 3 of the separating chamber 1 is located just above the upper end of the duct 9. The housing 4 further has a width drain 10 at the top in the form of a pipe mouth, which is connected via a line to a suction pump P. The housing 4 is at the top by means of, for example, a bayonet socket, indicated by 11, releasably fixed in a depression in the lower part of the separation chamber 1.

Tätningar 12 tätar höljets 4 och rörpartiets 6 övre kanter emot separeringskammaren 1.Seals 12 seal the upper edges of the housing 4 and the pipe section 6 against the separation chamber 1.

Genom att den tillförda vätskan med partiklar leds i en skruvlinjeformad bana längs separeringskammarens 1 väggar 10 15 20 25 30 35 40 462 201 kommer vätske-partikelblandningen att erhålla en roterande rörelseenergi och följa längs den koniskt avsmalnande öppning- ens 2 väggar och ut efter den utåtvikta kragen 3. Vätskan tillsammans med lätta partiklar kommer därvid att spridas solfjäderformigt runt hela periferin av kragen och lämna denna mer eller mindre horisontellt. Härigenom kommer lätta par- tiklar att föras åt sidan och hamna i den skruvlinjeformiga kanalen 13, som bildas av rörpartiets 6 flänsar 7 och den cylinderformade kanalen 9. Genom det avstannade vätskeflödet att falla rakt kommer tunga partiklar, som lämnar öppningen 2, ner genom kanalen 9 och uppsamlas på höljets 4 botten 5 innan- för filterorganet 8.By guiding the supplied liquid with particles in a helical path along the walls of the separation chamber 1, the liquid-particle mixture will obtain a rotating kinetic energy and follow along the walls of the conically tapered opening 2 and out after the outwardly folded the collar 3. The liquid together with light particles will then be distributed in a fan-shaped manner around the entire periphery of the collar and leave it more or less horizontal. As a result, light particles will be moved to the side and end up in the helical channel 13, which is formed by the flanges 7 of the pipe section 6 and the cylindrical channel 9. Due to the stopped liquid flow falling straight, heavy particles leaving the opening 2 will go down through the channel. 9 and is collected on the bottom 5 of the housing 4 inside the filter member 8.

När vätskan med de små partiklarna lämnar kragen 3 avtar rörelseenergin och kommer partiklarna under vätskans strömning nedåt i den skruvlinjeformiga kanalen 13 att till stor del avsätta sig på dennas väggar. Vätskan strömmar därefter genom filterorganet 8 och stiger uppåt genom den skruvlinjeformiga kanalen 14, som bildas mellan flänsarnas 7 utsida och höljets 4 insida. Under vätskans nu lugna rörelse uppåt kommer rester- ande del av partiklarna att sedimentera på flänsarnas 7 ut- sida, sà att när vätskan lämnar breddavloppet 10 är denna helt befriad från tyngre partiklar.When the liquid with the small particles leaves the collar 3, the kinetic energy decreases and during the flow of the liquid downwards in the helical channel 13 the particles will largely deposit on its walls. The liquid then flows through the filter means 8 and rises upwards through the helical channel 14, which is formed between the outside of the flanges 7 and the inside of the housing 4. During the now calm movement of the liquid upwards, the remaining part of the particles will settle on the outside of the flanges 7, so that when the liquid leaves the width drain 10 it is completely free of heavier particles.

När så befinnes lämpligt, beroende på typ av vätska och partiklar, avlägsnas filtret genom lossandet av bajonettfatt- ningen 11, varefter filtret kan deponeras på lämpligt sätt för eventuell återvinning av de i filtret uppsamlade partiklarna. Även om här talas om engångsbruk, är det naturligtvis inom ramen för uppfinningen möjligt att återanvända filtret efter rengöring, allt efter behov och lägenhet.When deemed appropriate, depending on the type of liquid and particles, the filter is removed by loosening the bayonet socket 11, after which the filter can be deposited in a suitable manner for any recovery of the particles collected in the filter. Although disposable use is mentioned here, it is of course possible within the scope of the invention to reuse the filter after cleaning, depending on the need and the apartment.

Sedimenteringen och uppsamlingen av vätskans partiklar blir enligt uppfinningen mycket effektiv genom att de lätta partiklarna skiljs från de tyngre partiklarna och att sedi- menteringen kan ske under mycket lugna förhållanden och på relativt sett stora ytor.According to the invention, the sedimentation and collection of the liquid particles becomes very efficient in that the light particles are separated from the heavier particles and that the sedimentation can take place under very calm conditions and on relatively large areas.

Det skall underförstàs att inom ramen för uppfinningen och för att underlätta utbyte av filter är breddavloppet 10 försett med en snabbkoppling för anslutning till utloppsled- ningen liksom är en sugpump P ej nödvändig för funktionen hos anordningen. Vidare kan höljet 4 liksom kanalen 9 och rör- partiet 6 göras svagt koniska för att förenkla tillverkning 462 201 och montering. Fastän ej uttalat nödvändigt kan passningen mellan delarna göras sådan, att höljet 4 och kanalen 9 tätande ansluter mot flänsarnas yttre resp, inre kanter. *rIt is to be understood that within the scope of the invention and to facilitate the replacement of filters, the width drain 10 is provided with a quick coupling for connection to the outlet line as well as a suction pump P is not necessary for the operation of the device. Furthermore, the housing 4 as well as the duct 9 and the pipe section 6 can be made slightly conical to simplify manufacture 462 201 and assembly. Although not expressly necessary, the fit between the parts can be made such that the housing 4 and the channel 9 sealingly connect to the outer and inner edges of the flanges. * r
