Description

15 20 25 464 966 fjädrande material, vilken skärm täcker och sluter slitsarna 2. Vid filtrering råder övertryck i bädden och skärmen vikes in och filtrat kan strömma in i huset. Vid spolning uppstår övertryck i huset, slitsarna 2 stängs, och utströnnande spolvatten öppnar öppningar 9, ca 12 mm bred spalt mellan husets underdel och platta 4. Denna spalt är vid filtrering täckt med fjädrande ring 3 av elastiskt fjädrande material. Resilient material, which screen covers and closes the slits 2. During filtration, there is overpressure in the bed and the screen is folded in and the filtrate can flow into the housing. During flushing, overpressure arises in the housing, the slits 2 close, and spreading rinsing water opens openings 9, approx. 12 mm wide gap between the lower part of the housing and plate 4. This gap is covered with resilient ring 3 of elastic resilient material during filtration.

Nu viker ringen ut inför det inre övertrycket. Yta eller båda två ytor, den ena på ringen och den andra på plattan 4 kan vara släta och härmed tätande mot varandra eller räfflade eller knottriga men grovleken mindre än bäddens korn så att även spalten 9 bidrar till att införa filtrat vid filtrering.Now the ring folds out in front of the inner overpressure. Surface or both two surfaces, one on the ring and the other on the plate 4 can be smooth and thus sealing against each other or knurled or lumpy but the coarseness less than the grain of the bed so that also the gap 9 contributes to introducing filtrate during filtration.

Fig. 2 avbildar en liknande fördelare, vänd nedåt och monterad på ett rör vid filterbotten. Här är slitsarna 2 anbragda i den elastiska ringen 3 och skärmen 5 är ändamålsenligt placerad på eller är en del av denna.Fig. 2 depicts a similar distributor, facing downwards and mounted on a pipe at the filter bottom. Here the slits 2 are arranged in the elastic ring 3 and the screen 5 is expediently placed on or is part of it.

Annat exempel är utförande avsett för filter, i vilka utströmning av spolvätskan och inledande av filtrand in i bädden sker md sanna strömriktning och element, medan filtratet avledes på ett annat ställe i bädden. Här är de smala slitsarna 2 för införande av filtrat onödiga och kan utgå.Another example is a design intended for filters, in which outflow of the rinsing liquid and introduction of filter sand into the bed takes place by true flow direction and elements, while the filtrate is diverted to another place in the bed. Here the narrow slits 2 for insertion of the filtrate are unnecessary and can be removed.

Fördelarna kan ha formen av en rotationskropp, vara fyr- eller flerkantiga, långsmala eller liknande. Införande av spolvätska resp. avledning av filtrat kan ske med hjälp av horisontella rör vid filterbottnen, vertikala rör eller dubbelbottnar, på vilka fördelarna är fastsatta.The advantages may be in the form of a rotating body, be square or polygonal, elongate or the like. Introduction of flushing fluid resp. filtration can be diverted by means of horizontal pipes at the filter bottom, vertical pipes or double bottoms, on which the advantages are attached.
