Abstract
Description
Oppfinnelsens gjenstand er en innretning til tilførsel og utslynging av etsnatronsmelte som i det vesentlige består av lutpumpe og slyngekurv. The object of the invention is a device for supplying and ejecting caustic soda melt which essentially consists of a lye pump and a sling basket.
Ved fremstilling av fast etsnatron eller Prill-fremgangsmåten tilføres etsnatronsmelte ved hjelp av en lutpumpe, f.eks. en dykkepumpe, til en slyngekurv hvormed den ved toppen av et Prill-tårn oppdeles i enkelte små dråper. Derved har det vist seg at innretningsdelene som spesielt kommer i berøring med den strømmengde etsnatronlut og evt. i tillegg med oksygen ligger under for en betraktelig slitasje enskjønt de er fremstilt av edelstål, nikkel, nikkellegeringer, sølv eller edelmetallegeringer. When producing solid caustic soda or the Prill method, caustic soda melt is added using a lye pump, e.g. a submersible pump, to a sling basket with which it is divided into individual small drops at the top of a Prill tower. Thereby, it has been shown that the equipment parts that come into contact with the flowing caustic soda and possibly also with oxygen are subject to considerable wear and tear, even though they are made of stainless steel, nickel, nickel alloys, silver or precious metal alloys.
Det besto følgelig den oppgave å tilveiebringe en innretning hvis deler som kommer i berøring med etsnatronsmelte er best mulig beskyttet mot slitasje. The task was therefore to provide a device whose parts that come into contact with caustic soda melt are as well protected against wear as possible.
Oppgaven løses Ifølge oppfinnelsen ved at Innretningens deler som kommer direkte i berøring med etsnatronsmelten består av glasskarbon eller er belagt med glasskarbon. According to the invention, the task is solved in that the parts of the Device that come into direct contact with the caustic soda melt consist of glassy carbon or are coated with glassy carbon.
Alle innretningens deler som deler av pumper, ventiler, rør rørbuer, armaturer, slyngekurver osv. som kommer i berøring med etsnatronsmelte kan bestå av glasskarbon respektiv belegges med glasskarbon. All parts of the device such as parts of pumps, valves, pipes, pipe bends, fittings, sling baskets etc. that come into contact with caustic soda melt can consist of glass carbon or be coated with glass carbon.
Oppfinnelsen skal forklares nærmere ved hjelp av to ek-sempler . The invention will be explained in more detail using two examples.
Fig. 1 viser en slyngekurv for etsnatronsmelte, og fig. 2 viser en dykkepumpe for etsnatronsmelte. Fig. 1 shows a sling basket for caustic soda melt, and fig. 2 shows a submersible pump for caustic soda melting.
Slyngekurven (fig. 1) består av en hylse 1 til opptak av drivaksen som Ikke er vist og bunndelen 2. På bunndelen 2 sitter mantelen 4 av kurven av glasskarbon med hullene 10 hvorigjennom etsnatronsmelten forstøves. Gjennom et dekke, en ring 3 og ankeret bestående av bolter 5, underlagsskiver 6 og muttere 7 holdes mantelen 4. Bunndelen 2 og hylsen 1 er beskyttet ved hjelp av en boks 8 og boltene 5 av hylser 9 av glasskarbon. 11 er tilførselsledninger for etsnatronsmelter som gjennom en ringspalte 12 rager inn i slyngekurven. The sling basket (fig. 1) consists of a sleeve 1 for receiving the drive shaft, which is not shown, and the bottom part 2. On the bottom part 2 sits the mantle 4 of the basket made of glass carbon with the holes 10 through which the caustic soda melt is atomized. Through a cover, a ring 3 and the anchor consisting of bolts 5, washers 6 and nuts 7, the mantle 4 is held. The bottom part 2 and the sleeve 1 are protected by means of a box 8 and the bolts 5 by sleeves 9 of glass carbon. 11 are supply lines for caustic soda melts that project through an annular gap 12 into the sling basket.
Pumpehuset av dykkepumpen (fig. 2) består av ledeinnretningen 13 og sugelokk 14. Navet av løpehjulet 15 rager gjennom ledeinnretningen 13 bestående av pumpehus 18, boks 17 og ledeskovler 19 og opptar drivakselen. Ledeinnretningen 13 har en boks 17 til beskyttelse av pumpehusdelen 18. Boksen 17 har ledeskovler 19. Likeledes er sugelokket 14 utstyrt med en boks 20 som beskytter lokket 14 og hvis stusser 21 tjener som sugerør for etsnatronsmelten. Sugelokk 14 og pumpehuset 18 begrenser en ringkanal 22 hvorover etsnatronsmelten tilføres til en utløpsstuss 23. I ringkanalen 22 er det anordnet en ledering 24. Boks 17 med ledeskovler 19, boks 20 med stusser 21 og pumpehjul er fremstilt av glasskarbon. Lederingen 24 kan likeledes bestå av glasskarbon. The pump housing of the submersible pump (fig. 2) consists of the guide device 13 and suction cap 14. The hub of the impeller 15 protrudes through the guide device 13 consisting of pump housing 18, box 17 and guide vanes 19 and occupies the drive shaft. The guide device 13 has a box 17 to protect the pump housing part 18. The box 17 has guide vanes 19. Likewise, the suction lid 14 is equipped with a box 20 which protects the lid 14 and whose nozzle 21 serves as a suction tube for the caustic soda melt. Suction cap 14 and pump housing 18 limit an annular channel 22 over which the caustic soda melt is supplied to an outlet nozzle 23. In the annular channel 22, a guide ring 24 is arranged. Box 17 with guide vanes 19, box 20 with nozzles 21 and impeller are made of carbon glass. The conductor ring 24 can likewise consist of glassy carbon.
