Description

Patenτ-Anspruch:Patenτ claim:

Sandfilter, bei welchem die Anordnung einer groben Kiesschicht dadurch umgangen wird,, dafs das Hauptsammeirohr (A) oberhalb der von dem Boden des Filters nach oben führenden Zuflufsstutzen (e) für das filtrirte Wasser liegt, so dafs letzteres von unten nach oben in das Sammelrohr geführt wird.Sand filter, in which the arrangement of a coarse layer of gravel is avoided by the fact that the main collecting pipe (A) lies above the inlet connection (e) leading from the bottom of the filter for the filtered water, so that the latter enters the collecting pipe from the bottom up to be led.

KAISERLICHESIMPERIAL PATENTAMT. \% PATENT OFFICE. \% KLASSE 8B: Wasserleitung.CLASS 8B: water pipe. F. ENGEL in HAMBURG. Sandfilter.F. ENGEL in HAMBURG. Sand filter. • Diese Erfindung besteht darin, bei Sandfiiteranlagen den Haupt - oder Sammelkanal über den unten offenen, rinnenförmigen oder röhrenförmigen Zweigkanä'len im Filtersande zu lagern. Der Zweck der Einrichtung ist einmal, das bei der seitherigen Anordnung des Sammelkanals unterhalb der Zweigkanäle nöthige tiefe Fundament für das Hauptrohr unterhalb des Filterbodens zu ersparen und weiter zu ermöglichen, die volle Höhe des Filters mit Filtersand auszufüllen und das seither stets erforderliche Auflager für den Filtersand, die groben Kies- oder Steinschichten zu beseitigen, indem bei oben genannter Anordnung kein Filtersand in das Sammelrohr gelangen kann.• This invention consists in the main or collecting channel in sand filter systems Above the channel-shaped or tubular branch channels in the filter sand, which are open at the bottom to store. The purpose of the establishment is once that of the previous arrangement of the collecting canal below the branch canals require a deep foundation for the main pipe to spare underneath the filter base and to further enable the full height of the To fill the filter with filter sand and the support for the filter sand, which has always been required since then, remove the coarse gravel or stone layers by using the above arrangement no filter sand can get into the collecting pipe. In beiliegender Zeichnung ist die Erfindung dargestellt, und zwar ist Fig. 1 ein Längendurchschnitt, Fig. 2 ein Querschnitt durch einen Theil einer solchen Filteranlage.In the accompanying drawing, the invention is shown, namely Fig. 1 is a longitudinal section, Fig. 2 is a cross-section through part of such a filter system. A ist das Sammelrohr, welches am unteren Ende mit den Zweigkanälen m, die rinnenförmig oder röhrenförmig gestaltet sind und am unteren Ende dem filtrirten Wasser Zutritt gestatten, durch die Rohrstutzen e verbunden ist. A is the collecting pipe, which is connected at the lower end to the branch ducts m, which are shaped like troughs or tubes and which allow access to the filtered water at the lower end, through the pipe sockets e. Ein besonderes Fundament unterhalb des Filters ist bei dieser Einrichtung für das Sammelrohr nicht nöthig, da dasselbe von den Rohrstutzen e oder von Trägern oder schmalen Mauerkörpern p, die sich auf den Boden des Filters stützen, direct getragen wird.A special foundation below the filter is not necessary for the collecting pipe with this device, since the same is directly supported by the pipe sockets e or by supports or narrow wall structures p which are supported on the bottom of the filter. Statt des sonst üblichen hohen Kieslagers am Grunde des Filters bedarf man nur eines sehr kleinen Quantums Kieses um die Eintrittsöffnungen der Zweigkanäle herum, da der feine Sand bei der Langsamkeit der steigenden Bewegung des Wassers nicht in das Hauptrohr A eintreten kann.Instead of the usual high gravel bed at the bottom of the filter, only a very small amount of gravel is required around the inlet openings of the branch channels, since the fine sand cannot enter the main pipe A given the slowness of the increasing movement of the water.
