Opis patentowy opublikowano: 30.09.1982 113823 Int. Cir'BOIff-7/24* C02C 1/06 CZYTELNIA Urredu Patentowego polnie) Uze^W *-\ ll;!*fci Twórca wynalazku: . Uprawniony z patentu: A1M-Laval Stalltechnik GmbtV Wieden ^Austria) Urzadzenie do wirowania i nagazowywania plynów Przedmiotem wynalazki* jest 'Urzadzenie do wi¬ rowania ^i nagazowywania .plynów* zwlaszcza na¬ wozu i scieków zawierajacych bakterie.Znane urzadzenia tego typu wyposazone sa w drazonyvwal ze sruba napedowa, skladajaca sie przynajmniej z jednejt lopatki o ksztalcie srubo¬ wym, posiadajacy na dolnym koncu lub z boku otwór wylotowy "gazu; Niedogodnoscia, tego rodzaju urzadzenia jest zasysanie\ do wirowanego plynu stosunkowo niewielkiej ilosci powietrza. •¦- Urzadzenie wedlug/wynalazku posiada napedza¬ ny wal drazony, na którym znajduje sie sruba1, na¬ pedowa z otworamfswylr/towymi gazu, przez które mozna wprowadzac gaz do plynów, przy czym sruba napedowa sklada sie z przynajmniej jednej lopatki o ksztalcie srubowym. Lopatka o ksztalcie srubowym rozszerza sie przy swej dolnej krawedzi w komore, polaczona kanalem z walem drazonym i tworzaca w kierunku stycznym otwór wylotowy.Przez umieszczone stycznie otwory wylotowe do plynu zostaje zasysana przez wal drazony, ko¬ more i otwory wylotowe nieoczekiwanie duza ilosc powietrza w trakcie akcji ssacej obracajacych sie lopatek.W urzadzeniu wedlug wynalazku komora jest utworzona przez dwie rozchodzace sie ku dolowi sciany o ksztalcie srubowym i ma przekrój w ksztalcie litery V o wierzcholku skierowanym na zewnatrz. Poniewaz predkosc obwodowa lopatki o ksztalcie srubowym jest najwieksza w strefie u 15 20 38 najmniejszego przekroju wylotowego, zatem naj¬ wieksza ilosc powietrza jest wyprowadzana z duza szybkoscia \przy zewnetrznych krawedziach sruby, przez co powietrze moze docierac takze do plynu znajdujacego sie przy sciankach zbiornika. Bardzo duzy stopien zasysania powietrza uzyskuje sie wówczas, jesli górna i dolna krawedz krzyzuja sie wzajemnie przy otworze wylotowym, przebiegajac promieniowo, przy czym dolna krawedz w strefie zewnetrznej, widziana w kierunku osiowym walu, znajduje sie ponad - krawedzia górna.Urzadzenie wedlug wynalazku zostalo objasnione przykladowo na rysunku, na którym fig. 1 przed¬ stawia widok zakonczenia sruby napedowej od strony swobodnego Jconca walu drazonego, fig. 2 — rzut pionowy sruby napedowej z fig. 1, a fig. 3 — przekrój wzdluz-Iiriii HI—III na iig. 1 i 2.Do drazonego walu 1 przyspawane sa trzy lo¬ patki 2, 3 i 4 o ksztalcie srubowym. W strefie dolnej wszystkie trzy lopatki 2, 3, 4 sa podzielone na dwie rozchodzace sie ku dolowi sciany 5, 6, two¬ rzace komore 4'. Komora 4* jest polaczona z wew¬ netrzna czescia drazonego walu 1 poprzez kanal laczacy 7. Przekrój poprzeczny komory 4* ma ksztalt litery V, której wierzcholek 8 jest skiero¬ wany na zewnatrz. Otwór wylotowy 10 kazdej z komór 4' jest ograniczony krawedzia górna 9 i krawedzia dolna 11, które widziane w kierunku osiowym walu 1, wzajemnie sie krzyzuja, przy 113 823113 823 czym krawedz dolna 11 w strefie zewnetrznej prze¬ chodzi ponad krawedzia górna.Poniewaz predkosc obwodowa lopatki jest naj¬ wieksza w strefie wierzcholka 8, gdzie jest naj¬ mniejszy przekrój poprzeczny wylotu, zatem po¬ wietrze, zasysane z walu drazonego 1, jest wypro¬ wadzane w strefie wierzcholka 8 ze szczególnie duza szybkoscia.
