Description

'8202223-7 10 15 ' 20 25 30 35 40 och FIG. 3 är en vertikalsektionsvy av centralröret i modifierat utförande. '8202223-7 10 15' 20 25 30 35 40 and FIG. 3 is a vertical sectional view of the central tube in a modified embodiment.

Cyklonavskiljaren innefattar en cylindrisk mantel l0 med ett tangentialinlopp ll för stoftbemängd fluid, såsom gas (luft) eller vätska. Nedtill ansluter sig manteln l0 till en bottenkon l2 och ett stoftutlopp l3, vilket i sin tur ansluter sig till ett stoftmagasin 14. Inuti manteln är anordnat ett centralrör 15, vilket är upphängt medelst ett vid manteln fäst gummimembran l6. Centralröret konar av mot sin nedre ände, inloppsänden, och har en utkragning l7 i denna ände. Koaxiellt inuti centralröret är anordnat ett filter 18, som likaledes konar av mot sin nedre, slutna ände. Även filtret uppbäres av membranet och kan lämpligen vara utbytbart fäst. Det kan bestå av pappers- eller textil- material eller av metallnät, keramiskt material eller plastmaterial eller också av olika kombinationer av dessa material enligt de inom filtertekniken allmänt tillämpade g principerna. Filtret är utformat med längsgående veck och är invändigt uppstagat medelst ett perforerat rör l9 av styvt material (papp, metall eller plast), vilket stöder filtret vid de invändtga vecken. Även detta rör uppbäres av membranet och det kan vara utfört som en enhet till- samman med filtret. Mellan filtret och centralröret är an- gordnad en ringspalt 20. En öppning 21 i en centralröret upptill tillslutande vägg 22 förbinder rörets l9 inre med~ ett utlopp 23 för fluid, som renats i cyklonavskiljaren.The cyclone separator comprises a cylindrical jacket 10 with a tangential inlet 11 for dust-laden fluid, such as gas (air) or liquid. At the bottom, the jacket 10 connects to a bottom cone 12 and a dust outlet 13, which in turn connects to a dust magazine 14. Inside the jacket is arranged a central tube 15, which is suspended by means of a rubber membrane 16 attached to the jacket. The central tube forms towards its lower end, the inlet end, and has a cantilever 17 at this end. Coaxially inside the central tube a filter 18 is arranged, which likewise kind of closes towards its lower, closed end. The filter is also supported by the membrane and can suitably be exchangeably attached. It can consist of paper or textile materials or of metal mesh, ceramic material or plastic material or also of different combinations of these materials according to the g principles generally applied in filter technology. The filter is designed with longitudinal folds and is internally supported by means of a perforated tube l9 of rigid material (cardboard, metal or plastic), which supports the filter at the inner folds. This tube is also supported by the membrane and it can be designed as a unit together with the filter. Arranged between the filter and the central pipe is an annular gap 20. An opening 21 in a central pipe at the top of the closing wall 22 connects the interior of the pipe 19 to an outlet 23 for fluid which has been purified in the cyclone separator.

Den förorenade fluiden passerar genom cyklonens inlopp ll och roterar längs cyklonens mantel l0, Föroreningar (stoftpartiklar) trycks tack vare centrifugalkraften ner till stoftmagasinet l4 och avskiljes där. Den renade fluiden, som fortfarande roterar, stiger upp mot centralrörets l5 in- lopp, där fluiden tvingas ut över den veckade ytan på filtret l8 i spalten 20. Den'veckade filterytan stabiliserar och bromsar upp resterande rotationskrafter så att en laminär fluidström fortsätter genom cyklonavskiljarens utlopp 23.The contaminated fluid passes through the inlet 11 of the cyclone and rotates along the jacket 10 of the cyclone. Contaminants (dust particles) are pushed down to the dust magazine 14 by the centrifugal force and separated there. The purified fluid, which is still rotating, rises toward the inlet of the central tube 15, where the fluid is forced out over the pleated surface of the filter 18 in the gap 20. The pleated filter surface stabilizes and slows down residual rotational forces so that a laminar fluid flow continues through the cyclone separator. outlet 23.

De fina stoftpartiklar, som ej kan avskiljas genom cyklonverkan, fastnar på filterytan. Genom den veckade filterkonstruktionen är filterytan relativt stor och ström- ningsförlusterna relativt små, så att stora finstoftmängder 10 l5 20 8202223-7 kan avskiljas i själva filterkonstruktionen. Vid avstäng- ning av luftflödet lossnar finpartiklarna från den veckade filterytan och ramlar ned till det avskilda stoftet i stoftmagasinet l4.The fine dust particles, which cannot be separated by cyclone action, stick to the filter surface. Due to the pleated filter construction, the filter surface is relatively large and the flow losses are relatively small, so that large amounts of fine dust can be separated in the filter construction itself. When the air flow is switched off, the fine particles detach from the pleated filter surface and fall down to the separated dust in the dust magazine l4.

Genom att filtret är veckat T sin längdriktning, er- hålles en högeffektiv cyklonavskilfiare. Filtret tjänstgör istället för ledskenor som medel för uppbromsning av den centrala cyklonvirveln, varigenom cyklonavskiljarens verk- ningsgrad höjes. Centralröret l5 tillsammans med filtret l8 utgör en kompakt enhet, som genom att den är upphängd i gummimembranet 16 kan på enkelt sätt skakas för rengöring av filterytan. Stoftpartiklar, som har fastnat på den vecka- de filterytan, ramlar då lätt ut genom centralröret och ned genom cyklonens nedre del till stoftmagasinet. .Because the filter is folded T its longitudinal direction, a highly efficient cyclone separator is obtained. Instead of guide rails, the filter serves as a means of braking the central cyclone vortex, thereby increasing the efficiency of the cyclone separator. The central tube 15 together with the filter 18 constitutes a compact unit which, by being suspended in the rubber membrane 16, can be easily shaken for cleaning the filter surface. Dust particles, which have stuck to the soaked filter surface, then easily fall out through the central tube and down through the lower part of the cyclone to the dust magazine. .

I utförandet enligt FIG. 3 är flera filter 18 av tidi- gare beskriven konstruktion anordnade i centralröret l5, vilket i detta fall sträcker sig nedanför filternas nedre ändar, varvid centralröret i den del, som sträcker sig ne- danför filtren, invändigt är försett med vingar eller led- skenor 24.In the embodiment according to FIG. 3, several filters 18 of previously described construction are arranged in the central tube 15, which in this case extends below the lower ends of the filters, the central tube in the part extending below the filters being internally provided with wings or guide rails 24.
