Description
i 151206
Opfindelsen angår et iblandings- og omrøreorgan af den i kravets indledning angivne art. Ved kendte organer til dette formål findes der en gasudstrømningsåbning ved den hule drivaksels nedre ende eller i akselens væg. Dette er ufordelagtigt derved, at der gennem den hule aksel kun kan suges forholdsvis små luftmængder ind i den omrørte væske.
Den foreliggende opfindelsen har til formål at afhjælpe denne mangel. Dette opnås ved det i kravets kendetegnende del angivne. Da skovlbladets periferihastighed er størst i zonen med det mindste udstrømningstværsnit, bringes den største mængde luft til at strømme ud med stor hastighed ved skruebladets ydre kanter, hvorfra luften endog kan udstrømme til den ydre zone i den væsken indeholdende tank. Der opnås en meget stor luftsugningshastighed ved, at de radialt rettede kanter, den øvre og den nedre kant, krydser hinanden ved udstrømningsåbningen, og ved, at den nedre kant i den ydre zone, i aksial retning strækker sig forbi den øvre kant.
I det følgende forklares opfindelsen nærmere ved hjælp af tegningen, hvor fig. 1 viser en udførelsesform for organet ifølge opfindelsen, set fra enden mod den hule aksels frie ende, fig. 2 viser organet, set fra siden, og fig. 3 er et snit efter linien 111 — 111 i fig. 1 og 2.
På tegningen ses en hul aksel 1 med tre på denne fast-svejsede skovlblade 2, 3 og 4. På organets nedre parti består de tre skovlblade hvert især af to nedadtil divergerende vægdele 5 og 6, der afgrænser et mellem dis- 151206 2 se beliggende kammer 4 med V-formet tværsnit. Kammeret 4 står i forbindelse med den hule aksel l's indre via en forbindelsesåbning 7. Det V-formede kammertværsnits spids 8 er rettet udad. Hvert af de tre kamre 4 har en udstrømningsåbning 10, der er afgrænset af en øvre kant 9 og en nedre kant 11. Disse to kanter krydser hinanden, set i aksial retning. Den nedre kant 11 rager i den perifere zone uden for den øvre kant 9, regnet i aksial retning. Da skovlbladenes periferihastighed er størst i den nærmest V-tværsnittets spids 8 beliggende zone, og da udstrømningsåbningen 10 her har sit mindste tværsnit, bringes den fra den hule aksel l's indre tilsugede luft til at udstrømme i zonen ved nævnte spids 8 med særlig stor hastighed.
Claims (1)
151206 Organ til iblanding af en luftart i en væske, især ajle eller bakterieholdigt spildevand, og til omrøring af væsken, med et på en drevet hul aksel (1) anbragt omrø-reelement med udstrømningsåbninger (10), gennem hvilke luftarten fra den hule aksels indre kan tilføres væsken, og hvor omrøreelementet består af mindst ét skovlblad, fortrinsvis tre skovlblade (2, 3, 4), kendetegnet ved, at et nedre parti af skovlbladet eller af hvert af de tre skovlblade er dannet af to nedadtil divergerende vægge (5, 6), der afgrænser et kammer (4) med et V-formet tværsnit med V'ets spids (8) beliggende radialt yderst, og med en tangentialt rettet udstrømningsåbning (10), der er afgrænset af to radialt forløbende kanter, nemlig en øvre kant (9) og en nedre kant (11), som krydser hinanden, og af hvilke den nedre kant (11) rager aksialt uden for den øvre kant (9).
