Anordnin,g vid centrifuger med kanalformiga behallare for de amnen, som skola centrifugeras, vilka behallare aro stallbara i vissa vinkel- lagen relativt en desamma uppbarande drivaxel. Arrangements for centrifuges with channel-shaped containers for the workpieces to be centrifuged, which containers are adjustable in certain angular layers relative to the same supporting drive shaft.

Man sokte aven upphanga roren sa kring rotationsaxeln, att de kunde pendla fritt kring denna och daryid sla ut horisontellt eller begransades deras utslag, men vid centrifugeringens hastiga upphorande uppstod latt vatskerorelser i det avsatta sedimentet. Dessa olagenheter har man sOkt und-vika genom rorens anbringande i kapor, som forhoja syangmassan och darigenom motverka de el-jest vid hastigt avstannande av centrifugeringen uppsthende yatskerorelserna och ayen sat reglera hallarnas installning genom en for samtliga gemensam, hallarnas Overdelar paverkande omstallningsanordning, besthende av ett organ forsett med utsprang, vridbart kring centrifugens axel och vilket kan vridas till ett eller flera lagen, i vilka utsprangen begransa rorhallarnas utslag, eventuellt i olika hog grad, varvid emellertid utsprangen for varje gang sadan lageforandring onskas maste utbytas ph drivaxeln.

In hitherto known devices for sedimentation of particles suspended in liquid, in which the centrifugal force serves as a sedimenting force, and which consisted of fixed tubes attached to a rotatable shaft for receiving the particle slurries which are to be sedimented, it has been set up in various ways to install those slurries. holding the rudder's bearing in relation to the axis of rotation. If the longitudinal axis of the "tubes is perpendicular to the axis of rotation, very high rotational speeds must be required and it was therefore soon necessary to fasten the tubes in holders, fixed around. The axis of rotation arranged, evenly displaceable arms, but delta sktt did not allow flake after Onskan yald yinkel installation Every special root '. They also sought to hang the pipes around the axis of rotation, that they could oscillate freely around it and daryid strike out horizontally or their rash was limited, but at the rapid cessation of centrifugation, water disturbances easily occurred in the deposited sediment. -fold through the placement of the rudder in hoods, which increase the syang mass and thereby counteract the y-cutting arising at the rapid cessation of the centrifugation and ayen sat regulate the installation of the halls by a common adjustment device rotatable around centrifuge shaft and which can be rotated to one or more layers, in which the projections delimit the deflections of the rudder halls, possibly to varying degrees, whereby, however, the projections must be replaced by the drive shaft each time such a change in position is desired. This significant irregularity is avoided by the present device, which with a light grip allows change of position relative to the axis of rotation for which it is raised by occurring root, at the same time as the tubes can be installed in pairs in equal angular layers, so that the weight is equally radial and diametrical to system balancing.

Fig. 1 a denna ritning yisar en vertikalsektion ay en med ifragavarande anordning forsedd centrifug och fig. 2 visar en sektion ay en av de behallare, van i det anme som skall centrifugeras anbringas. Fig. 1 a of this drawing shows a vertical section ay of a centrifuge provided with the device in question and Fig. 2 shows a section ay of one of the containers, used in the container to be centrifuged.

A ritningen betecknar 3 en fat, lampligen koniskt utformad, vilken uppbar en skalformig behallare 4. Inuti foten 3 an en drivmotor 5 anordnad, vars axel 6 stracker sig vertikalt uppat i skalen 4. A axeln 6 är en hylsformig hallare 7 fastgjord, vilken a nedre partiet ãr forseddmed en flansformig del 8. A denna flansformiga del 8 aro bagformiga stodorgan 9 fastgjorda medelst skruvar 10. Ovre andpartierna a hal- 2— — larna 9 hophallas medelst en ring 11. Det avre partiet hallaren 7 är farsett med radiellt utatriktade organ 12, mellan vilka centrifugeringsbehallare 13 aro ledbart lagrade medelst axeltappar 14. Centrifugeringsbehallarna 13, i det liar foreliggande fallet fyra stycken, besta av rör av lampligt metalliskt material, vilka aro forsedda med en botten 15. Det ena andpartiet 5. resp. behallare är forsett med en flans 16, -Olken anligger mot ett ringformigt organ 17. De tidigare i samband med fig. 1 beskrivna axeltapparna 14 are anordnade a ringen 17, vilken fastgares mot flansen 16 medelst en. ringmutter 18. Behallaren 13 ãr skjutbart anordnad i en med en botten 19 forsedd hylsformig del 20. Inuti den hylsformiga delen 20 är en fjader 21 anbragt som anligger mot botten 15 a behallaren 13. Hylsan 20 fir a botten 19 forsedd med en axiellt riktad kam 22, vilken är f orsedd med ett spar 23. De bagformiga staden '9 aro forsedda med ett antal spar 24, i vilka det inre kantpartiet i sparet 23 a den hylsformiga delen 20 bringas att anligga, da behallaren 13 installes i ett visst vinkellage relativt axeln 6. In the drawing 3 denotes a barrel, suitably conically shaped, which carried a shell-shaped container 4. Inside the foot 3 arranged a drive motor 5, the shaft 6 of which extends vertically upwards in the shells 4. A shaft 6 is a sleeve-shaped holder 7 fixed, which a the lower part is provided with a flange-shaped part 8. In this flange-shaped part 8 are rear-shaped support members 9 fastened by means of screws 10. The upper end portions of the halls 9 are held together by means of a ring 11. The lower part the holder 7 is forged with radially outwardly directed members 12, between which centrifugation containers 13 are articulated by means of shaft pins 14. The centrifugation containers 13, in the present case four pieces, consist of tubes of light metallic material, which are provided with a bottom 15. One duck portion 5. resp. container is provided with a flange 16, - The beam abuts against an annular member 17. The shaft pins 14 previously described in connection with Fig. 1 are arranged on the ring 17, which is fastened to the flange 16 by means of a. ring nut 18. The container 13 is slidably arranged in a sleeve-shaped part 20 provided with a bottom 19. Inside the sleeve-shaped part 20 a spring 21 is arranged which abuts against the bottom 15 of the container 13. The sleeve 20 for the bottom 19 is provided with an axially directed cam 22, which is provided with a groove 23. The bag-shaped cities 9 are provided with a number of grooves 24, in which the inner edge portion of the groove 23 a the sleeve-shaped part 20 is brought to abut, when the container 13 is installed in a certain angular layer relative to shoulder 6.

Fjadern 21, som trycker hylsan 20 mot endera av de bagformiga stodorganen 9, tjanar till att kvarhalla behallaren 13 i det installda Ninkellaget. Da. behallarna 13 jamte hylsorna 20 skola f6rflyttas fran ett av sparen 24 till ett annat spar a stoden. 9, fares hylsan 20 mat behallaren tills namnda hylsa lasgares fran resp. stad, varefter forflyttning av resp. behallare kan aga rum. The spring 21, which presses the sleeve 20 against either of the rear-shaped support members 9, serves to retain the container 13 in the installed Ninkel layer. Yes. the containers 13 and the sleeves 20 are to be moved from one of the grooves 24 to another groove on the pillar. 9, the sleeve 20 is fed to the container until the said sleeve is removed from resp. city, after which transfer of resp. containers can aga rum.

Darest olika amnen, vilka skola centrifugeras med olika centrifugalverkan, aro faremal for undersokning, kan detta astadkommas samtidigt med en centrifug enligt uppfinningen. If different substances, which are to be centrifuged with different centrifugal effects, are dangerous for examination, this can be achieved simultaneously with a centrifuge according to the invention.

Centrifugeringsbehallarna installas parvis i lika vinkellagen sa att tyngden blir lika radiellt och diametralt relativt drivaxeln med hansyn till utbalanseringen av systemet. The centrifugation tanks are installed in pairs in equal angular layers so that the weight becomes equally radial and diametrical relative to the drive shaft with regard to the balancing of the system.

Den skalformiga behallaren 4, i vilken centrifugens vitala delar aro anordnade, tillslutes med ett lock 25. The shell-shaped container 4, in which the vital parts of the centrifuge are arranged, is closed with a lid 25.
