Description

Uppfinnare: G A Larsson Denna uppfinning avser en cellmatare, avsedd for pulver- eller kornformigt material och besthende av ett cylindriskt hus med inlopp och utlopp for materialet och ett i huset inpassat cellhjul. Inventor: G A Larsson This invention relates to a cell feeder, intended for powdery or granular material and consisting of a cylindrical housing with inlet and outlet for the material and a cell wheel fitted in the housing.

Sadana anordningar anvandas ofta for att slussa igenom flytande material mellan tva rum med olika tryck, och de kunna Sven anvandas for pulver- eller kornformiga material. Vid slussning av sadant torrt material, t. ex. cement, som har stor adhesionsformaga, hlir emellertid befordringsmangden inte sa stor, som den horde bli, beroende dels pa att alltfOr mycket av materialet hanger kvar i cellhjulets celler och bara Aker runt, dels p5 svarigheten att fOra materialet vidare genom en rorledning fran cellmatarens utlopp. Such devices are often used to pass liquid material between two chambers of different pressures, and they can be used for powdery or granular materials. When sluice of such dry material, e.g. cement, which has a large adhesion capacity, however, the amount of transport is not as great as it should be, partly due to the fact that too much of the material remains in the cells of the cell wheel and only Aker around, partly due to the responsibility to carry the material further through a pipeline from the cell feeder outlet .

Uppfinningen syftar till att avhjalpa dessa brister genom en forbattrad konstruktion av cellmataren, och denna konstruktion kannetecknas darav, att var och en av cellmatarens celler medelst en poros skiljevagg Sr delad i en befordringskammare, som under cellhjulets rotation kommer i fOrbindelse med inloppet och utloppet vaxelvis, och en luftkammare, och att huset har en lufttilloppsoppning, sa belagen, att den leder in till luftkammaren i den cell, vars befordringskammare for tillfallet har eller just Sr pa vag att fa forbindelse med utloppet. The invention aims to remedy these shortcomings by an improved construction of the cell feeder, and this construction can be characterized in that each of the cells of the cell feeder is divided by means of a porous partition Sr in a transport chamber, which during rotation of the cell wheel communicates with the inlet and outlet alternately. and an air chamber, and that the housing has an air inlet opening, so coated that it leads into the air chamber of the cell whose carriage chamber for the occasion has or is just about to be connected to the outlet.

Om cellmataren skall avge materialet till en sugledning, kan detta vara tillrackligt, och om atmosfarstryck eller h8gre tryck racier pa utloppssidan, anslutes en tryckluftledning till lufttilloppsoppningen, sh, att i hada fallen luft pressas in i den ifragavarande luftkammaren. Denim luft sipprar igenom den porosa skiljevaggen till befordringskammaren och fluidiserar materialet i denna, sa att det med latthet avgar genom utloppet och gar vidare genom en till detta ansluten ror- eller slangledning. Darvid -Volumes befordringskammaren praktiskt taget fullstandigt, och cellmatarens volumetriska verkningsgrad kan pa detta salt komma mycket nara 100 %. If the cell feeder is to deliver the material to a suction line, this may be sufficient, and if atmospheric pressure or higher pressure racier on the outlet side, a compressed air line is connected to the air inlet opening, in which case air is forced into the air chamber in question. Denim air seeps through the porous partition to the carriage chamber and fluidizes the material therein, so that it easily exits through the outlet and passes further through a pipe or hose line connected thereto. Thereby -Volumes the transport chamber is practically complete, and the volumetric efficiency of the cell feeder on this salt can come very close to 100%.

En enligt uppfinningen konstruerad cellmatare visas pa bifogad ritning, varvid fig. 1 visar en vertikal axialsektion och fig. 2 visar dels en tvarsektion, dels en andvy frau hiiger enligt fig. 1. A cell feeder constructed according to the invention is shown in the accompanying drawing, wherein Fig. 1 shows a vertical axial section and Fig. 2 shows partly a cross section and partly a view from above according to Fig. 1.

Den visade cellmataren, som Sr avsedd att arbeta vertikalt nedat, har ett hus 1 i form av en liggande cylinder, bestaende av en mantel 2 och ett par gavlar 3, 4. Huset har ph mantelns oversida en inloppsstuts 5, avsedd att underifran anslutas till en behallare eller rorledning, och ph mantelns undersida en utloppsstuts 6, till vilken visas anslutet ett vinkelbojt utloppsror 7. The cell feeder shown, which Sr is intended to work vertically downwards, has a housing 1 in the form of a horizontal cylinder, consisting of a jacket 2 and a pair of ends 3, 4. The housing has the upper side of the ph jacket an inlet connection 5, intended to be connected from below to a container or pipeline, and the underside of the ph jacket an outlet spout 6, to which is shown an angle-bent outlet pipe 7.

Huset 1 innehaller ett cellhjul 8, som be-star av en axel 9, ett par gavlar 10, 11, nagra skovlar 12, i detta fall sex, och ett motsvarande antal porosa skiljevaggar 13, som dela de sektorformade cellerna mellan skovlarna 12 i en inre luftkammare 14 och en yttre befordringskammare 15. Cellhjulet Sr viii avtatat mot husets insida. Salunda aro skovlarnas yttre delar 16 gjorda av elastiskt material, t. ex. tunn sthlplat, och nagot bOjda nara ytterkanten for att med fjaderkraft hSfla denna kant i kontakt med husets mantel. Vidare arc filtringar 17 inlagda mellan husets och cellhjulets gavlar, och dSrtill kan man pressa in felt mellan gavlarna innanfor filtringarna, varvid fullstandig tatning erhalles pa detta stalle. The housing 1 contains a cell wheel 8, which consists of a shaft 9, a pair of ends 10, 11, some vanes 12, in this case six, and a corresponding number of porous partitions 13, which divide the sector-shaped cells between the vanes 12 in a inner air chamber 14 and an outer carriage chamber 15. The cell wheel Sr viii sloping towards the inside of the housing. Salunda aro the outer parts 16 of the blades are made of elastic material, e.g. thin steel plate, and slightly bend near the outer edge to bring this edge into contact with the housing mantle with spring force. Furthermore, filters 17 are inserted between the ends of the housing and the cell wheel, and in addition fields can be pressed in between the ends inside the filters, whereby a complete seal is obtained in this place.

Vid den hogra gaveln enligt fig. 1 har cellhjulet en grov hylsa 18, som Sr fastsatt ph axeln 9 och i ett centralt hal i hjulgaveln 10 samt lagrad i ett lager 19 utanpa husets gavel 3 och avtatad i denna gavel medelst en lilting 20. Denna hylsa 18 har sex axiellt genoinghende hal 21, jamnt fordelade ph en cirkel och ledande in till var sin av cellhjulets luftkamrar. Mot hylsans 18 yttre andyta anligger ett lock 22, fodrat med en fiberski-va 2— — 23. Denna och locket ha ett hal 24 i den nedre delen ph samma cirkel som hylsans 18 hal 21, sa att dessa i tur och ordning komma att sammanfalla med halet 24 under cellhjulets rotation. Locket 22 har ocksa en stuts 25 omkring halet 24 far anslutning av en tryckluftledning. Locket har pa kanten tre axiellt riktade styrpinnar 26, som aro inforda i hSl 27 i lagret 19, och for varje styrpinne finnas tre hal 27 att valja pa, s. att halet 24 kan stallas i olika lagen utmed haleirkeln. Vid den ins-Wining, som visas i fig. 2, kommer varje luftkammare 14 i forbindelse med stutsen 25 strax innan motsvarande befordringskammare 15 kommer i ferbindelse med utloppsstutsen 6, sa att det i befordringskammaren. befintliga materialet h&j ar fluidiseras, innan utmatningen borjar, men detta an en sak, som far regleras i varje sarskilt fall med hansyn till materialets beskaffenhet, lufttrycket och andra omstandigheter. Locket 22 fasthalles mot hylsan 18 av en. bult 28 med muttrar 29, vilken Sr infard i en central urborrning i axeln. 9 och lagrad i denna medelst ett axiallager 30. At the right end of Fig. 1, the cell wheel has a coarse sleeve 18, which Sr attached to the shaft 9 and in a central hall in the wheel end 10 and stored in a bearing 19 outside the end of the housing 3 and decelerated in this end by means of a lilting 20. This sleeve 18 has six axially continuous slides 21, evenly distributed ph a circle and leading into each of the air chambers of the cell wheel. Against the outer end face of the sleeve 18 abuts a cover 22, lined with a fibreboard 2-23. coincide with the tail 24 during the rotation of the cell wheel. The cover 22 also has a spigot 25 around the tail 24 for connection of a compressed air line. The lid has on the edge three axially directed guide pins 26, which are inserted in hSl 27 in the bearing 19, and for each guide pin there are three holes 27 to choose from, so that the tail 24 can be placed in different layers along the tail circle. At the ins-Wining shown in Fig. 2, each air chamber 14 communicates with the nozzle 25 just before the corresponding conveyor chamber 15 comes into communication with the outlet nozzle 6, so that it enters the conveyor chamber. The existing material is fluidized before the discharge begins, but this is a matter which must be regulated in each particular case with regard to the nature of the material, the air pressure and other conditions. The lid 22 is held against the sleeve 18 by a. bolt 28 with nuts 29, which Sr enters a central bore in the shaft. 9 and mounted therein by means of an axial bearing 30.

Vid den vanstra &laden enligt fig. 1 Sr axeln 9 avtatad medelst en filtring 31 i husets gavel 4 och utanfor denna lagrad i ett pa huset monterat lager 32 samt forsedd med ett kedjehjul 33 for att drivas av en pa huset monterad motor 34. In the case of the left-hand load according to Fig. 1, the shaft 9 is decelerated by means of a filter 31 in the end wall 4 of the housing and mounted outside it in a bearing 32 mounted on the housing and provided with a sprocket 33 to be driven by a motor 34 mounted on the housing.

I det visade utforandet Sr ett ror 35 infort i rorbojningen 7 for inblasning av luft i denna i andamal att driva materialet vidare frau cellmataren under bibehallande av dess fluidiserade tillstand, och denna luftinblasning kan ocksa astadkomma en viss sugning frau eellmataren och saledes bidraga till dennas effektivitet. In the embodiment shown, a tube 35 is inserted into the rudder bend 7 for blowing air therein in order to propel the material further from the cell feeder while maintaining its fluidized state, and this air blowing can also cause a certain suction from the cell feeder and thus contribute to its efficiency. .

Givetvis Sr det icke nodvandigt att anvanda just luft for fluidiseringen; i vissa fall kan nagon annan gas vara att foredraga, t. ex. vid handhavande av eldfangt material. Of course, it is not necessary to use just air for the fluidization; in some cases some other gas may be preferable, e.g. when handling flammable material.
