Definitions

  • the invention relates to a cistern with an inlet, in which a arranged in a filter housing rainwater filter is located, wherein a first output of the filter housing by means of a communicating tube in communication with the plenum of the cistern and has a filtered connection with the inlet and a second outlet of the filter housing communicates with a cistern bypassing the collecting chamber and has an unfiltered connection with the inlet, and with an overflow having an input into the secondary line.
  • Such cisterns are used for collecting rainwater. They usually consist of a multi-cubic meter KunststoffStoff practicer, which is placed underground. The rainwater filter is arranged in such a way that coarse contaminants of the inflowing rainwater do not enter the cistern's collecting space, but rather are diverted into a secondary line which is in direct communication with the sewage system. The overflow of the cistern is connected to the secondary line.
  • the drain pipe which forms the secondary line, passes through the collecting space of the cistern, wherein the overflow within the collecting space adjoins the secondary line.
  • This has the advantage that contamination of the cistern water, which settle in a floating layer on the cistern water, be washed away in the overflow of the cistern. Because of the overflow but is in the plenum of the cistern, but this applies only to the existing swimming layer, but not that which is located in the communicating tube, which connects to the first output of the rainwater filter.
  • the invention is therefore based on the task of designing the cistern so that in an overflow of the cistern and the area of the communicating tube is cleaned.
  • the invention provides that the inlet of the overflow is located in the flow direction of the rainwater flowing into the collecting space of the cistern in front of the end of the communicating tube which plunges into the collecting space.
  • the first outlet is in connection with a downpipe which opens out over the bottom of the cistern.
  • a downpipe which opens out over the bottom of the cistern.
  • the invention further provides that the inlet of the overflow is located below the filter surface. So before the water level in the cistern or in the filter housing can reach the filter surface, the water flows through the overflow.

  • water is drawn through the filter surface from the vertically falling through the interior dirty water stream in an annular space surrounding the filter surface by adhesion, the impurities are rinsed with the residual water through the second output at the lower end of the interior to the secondary line. Since in this type of rainwater filters, the impurities do not stick to the filter surface, this rarely needs to be cleaned.
  • the invention provides that the entrance to the overflow opens into this annular space. This allows a very simple construction of the filter housing.
  • the annulus has a horizontally extending floor with the entrance above the floor. This allows filter water to collect in the annulus, without it draining into the secondary line. So even if no filtered water is lost, the filter water in the annulus may accumulate in the event of a large amount of water before it can drain into the cistern through the first outlet.

At the bottom end of the downpipe 11 there is an inlet chiller (not shown here), which ensures that the water flows into the collecting chamber 5 of the cistern 1 without turbulence and delayed.

  • the opening 20 is an obliquely extending cover 21, which prevents the filter water emerging from the rainwater filter above the opening from entering the overflow directly. Since the cover 21 is arranged at a distance from the opening 20, water rising from below can enter the opening 20.
  • FIG. 3 shows a vertical section through the filter housing 7 with the rainwater filter 8.
  • the dirty water passes through the inlet 6 (see Fig. 1) in the filter housing 7 and thus in the interior of the rainwater filter 8.
  • the orientation of the inlet 6 causes a tangential inflow, so that the Dirty water mainly along the inside of the filter surface along and is sucked by adhesion forces radially outward through the filter surface.
  • the filtered water thus enters an annular space 22 between the rainwater filter 8 and the filter housing 7 and can pass from there via the first outlet 10 and the downpipe 11 into the plenum 5 of the cistern 1. Dirty water that is not sucked through the rainwater filter 8, coincides with the coarse pollution by the hole 16 in the bottom 14 and from there via the drain pipe 18 into the sewer.
  • the cistern 1 fills gradually, wherein the collecting space 5 of the cistern 1 and the downcomer 11 are in a communicating connection, so that the water level in the collecting space 5 and the downpipe 11 is the same.
  • the rainwater filter can not filter out all contaminants, such as microbial and bacterial suspended particles. These accumulate on the water surface in the downpipe 11. Since the above-mentioned inlet calmer provides for a slow transition to the plenum 5, the suspended particles always have enough time to get in the downpipe 11 up to the water surface, before it flows from the inflowing into the plenum 5 water get picked up. At the water surface they form a so-called floating layer. If the water level rises, it reaches the opening 20 which acts as an overflow. The water can now flow into the sewage system via the drain pipe 18 acting as a branch pipe. The floating layer is entrained, whereby the water is freed from impurities in the downpipe.

Abstract

L'invention vise à faciliter l'élimination des particules en suspension dans une eau de citerne, ces particules s'étant accumulées sous la forme d'une couche surnageante, et par ailleurs à créer un boîtier de filtre pour un filtre à eau de pluie qui soit de conception simple et facile à fabriquer. À cet effet, le boîtier de filtre, qui présente une surface latérale extérieure cylindrique et un fond (14), est pourvu d'une première sortie (10) pour l'eau filtrée et, dans la partie centrale du fond (14), d'une seconde sortie (12) pour l'eau sale non filtrée, cette seconde sortie (12) étant reliée à un tuyau d'évacuation (18). Ce tuyau d'évacuation (18) comporte une section qui s'étend parallèlement au fond (14) et dans la paroi de laquelle est ménagée une ouverture (20) au-dessus du fond, cette ouverture (20) servant de trop-plein pour la citerne.
