Abstract

The centrifuge bowl 1 is provided with a separator plate 9 in the spacer fillets 11 of which feed channels 14 are provided for a diluting liquid. The feed channels 14 lead from a central feed chamber 15 to a peripheral region 7 of the centrifuge bowl 1. The addition of diluting liquid into the peripheral region 7 enables the problem-free withdrawal of a heavy product phase of pasty consistency via the delivery channels 12 in the separator plate 9. Slime and solid matter is ejected through valve (6) - controlled openings 8. It is used in refining of animal and vegetable oils and fats. <IMAGE>

Description

507 10 15 20 25 30 35 040 2 vilka leder från en central matarkammare till centrifu- galtrummans periferiområde. 507 10 15 20 25 30 35 040 2 which lead from a central feed chamber to the peripheral area of the centrifugal drum.

Genom tillförsel av utspädningsvätska i centrifu- galtrummans periferiområde utspäds den överflödiga luten efter neutralisering av de fria fettsyrorna med koncen- trerad lut och minskas tvålens viskositet. Lut-tvål- blandningen dräneras sedan utan problem via avloppet för de tunga komponenterna.By adding diluent in the peripheral area of the centrifugal drum, the excess lye is diluted after neutralization of the free fatty acids with concentrated lye and the viscosity of the soap is reduced. The lye-soap mixture is then drained without problems via the drain for the heavy components.

Hos en föredragen utföringsform är tillförselkana- lerna inrättade i separertallriken. Därmed erhålles en konstruktivt enkel lösning.In a preferred embodiment, the supply channels are arranged in the separator plate. This provides a constructively simple solution.

Hos en annan, fördelaktig utföringsform utgörs se- parertallriken av en konisk tallrik med på sin ovansida anbringade avståndselement, samt är tillförselkanalerna utsträckta innanför avståndselementen. Denna utförings- form kräver ingen ytterligare plats i centrifugaltrum- man, eftersom separertallriken har samma kontur som vid utföringsformen utan tillförselkanaler.In another, advantageous embodiment, the separating plate consists of a conical plate with spacer elements arranged on its upper side, and the supply channels are extended inside the spacer elements. This embodiment does not require any additional space in the centrifugal drum, since the separator plate has the same contour as in the embodiment without supply channels.

Ett utföringsexempel av föreliggande uppfinning be- skrivs närmare i det följande under hänvisning till bi- fogad ritning.An embodiment of the present invention is described in more detail below with reference to the accompanying drawing.

Med 1 på ritningen betecknas centrifugaltrumman, vars huvudbeståndsdelar är en trumunderdel 2, ett trum- lock 3, en fördelare 4 och en tallriksinsats 5. I trum- underdelen 2 är det inrättat en kolvslid 6 som är hy- draulisk förflyttbar i axiell riktning och därvid friger eller tillsluter i trumunderdelens 2 periferiområde 7 inrättade avloppsöppningar 8. Ovanför tallriksinsatsen 5 är det anordnat en separertallrik 9 som utgörs av en ko- nisk tallrik 10 med på sin ovansida anbringade avstånds- element 11 som ligger an mot trumlocket 3 och därvid bildar avloppskanalerna 12, vilka mynnar i en central avloppskammare 13. Innanför avståndselementen 10 är tillförselkanaler 14 utsträckta, vilka leder från peri- feriområdet 7 till en central matarkammare 15. Från tallriksinsatsens 5 centrum leder i fördelaren 4 inrät- 10 15 20 507 040 3 tade kanaler 16 till en andra avloppskammare 17. I av- loppskamrarna 13, 17 är det inrättat skalorgan 18, 19 som är förbundna med avlopp 20, 21 för den tunga respek- tiva den lätta fasen hos blandningen. I fördelarens 5 centrum är det inrättat en inloppskammare 22 som via ett inloppsrör 23 förses med produkten. För tillförsel av utspädningsvätska är det inrättat en kopplingsfläns 24.1 in the drawing denotes the centrifugal drum, the main components of which are a drum lower part 2, a drum lid 3, a distributor 4 and a plate insert 5. In the drum lower part 2 a piston slide 6 is arranged which is hydraulically displaceable in the axial direction and thereby frees or closes drainage openings 8 arranged in the peripheral area 7 of the drum lower part 2. , which open into a central drain chamber 13. Inside the spacer elements 10, supply ducts 14 are extended, which lead from the peripheral area 7 to a central feed chamber 15. From the center of the plate insert 5 lead in the distributor 4 arranged channels 16 to a second drain chamber 17. In the drain chambers 13, 17, shell means 18, 19 are arranged which are connected to drains 20, 21 for the heavy travel. pective the light phase of the mixture. In the center of the distributor 5 an inlet chamber 22 is arranged which is supplied with the product via an inlet pipe 23. A supply flange 24 is provided for the supply of diluent liquid.

Vätske-fastkropp-blandningen leds via inloppsröret 23 till centrifugaltrumman 1 och separeras i tallriks- insatsen 5. Blandningens lätta fas strömmar inåt och ma- tas via kanalerna 16 och skalskivan 19 till avloppet 21 för den lätta fasen.The liquid-solid mixture is led via the inlet tube 23 to the centrifugal drum 1 and separated in the plate insert 5. The light phase of the mixture flows inwards and is fed via the channels 16 and the shell disc 19 to the drain 21 for the light phase.

Den tunga fasen flyter utåt, späds ut av den via kopplingsflänsen 24, matarkammaren 15 och tillförsel- kanalerna 14 tillförda utspädningsvätskan, och matas sedan via avloppskanalerna 12, avloppskammaren 13 och skalorganet 19 till avloppet 20 för den tunga fasen.The heavy phase flows outwards, is diluted by the diluent supplied via the coupling flange 24, the feed chamber 15 and the supply channels 14, and is then fed via the drain channels 12, the drain chamber 13 and the shell member 19 to the drain 20 for the heavy phase.

Slem och fasta partiklar som samlas i periferiområ- det 7 matas då och då ut genom avloppsöppningen 8 genom manövrering av kolvsliden 6.Mucus and solid particles which collect in the peripheral area 7 are occasionally discharged through the drain opening 8 by maneuvering the piston slide 6.
