Definitions
- the object is a device for separating the Solids from liquid-solid mixtures according to Preamble of claim 1.
- the known devices have the disadvantage that solids settle on the container walls and consequently the entire container has to be emptied and cleaned from time to time. Mixing of the liquid collected in the container is more or less random.
- Very complex, sophisticated dirt separating devices are also known (EP-A1 0 448 282), in which the liquid loaded with solids is guided through different chambers or chamber parts of a container.
- these known devices are only suitable for pressurized containers, but not for those that work in principle without pressure, as is usually the case with rain water systems. Their construction is also expensive to manufacture and maintain.
- the object of the present invention is to create a device that requires little technical effort causes a high degree of cleaning.
- a spiral rib is formed at the bottom of the container and the sedimentation area is designed as a sump.
- the removal of the liquid freed from solids takes place radially outside the sedimentation area and is also protected behind a spiral rib.
- a cylindrical tube with an inserted base or a conical or spherical hollow body can be used as the container.
- the container with the channel is inserted into a space that is many times larger, and the process water is led out of the container through one or more openings in the base area.
- the larger room can be an existing tank.
- Another particularly advantageous and inexpensive embodiment of the invention comprises, instead of the V-shaped channel, a helically guided pipe along the wall of the container, which has outlet openings for the water at intervals in the apex, ie is designed in sections as a semicircular channel.
- the device for separating solids from Liquid-solid mixtures include one Separation tank, called tank 1 for short, with a wall 3.
- the container 1 has one cylindrical wall 3.
- the wall 3 could be conical downwards, i.e. of the Container 1 could be an upside down truncated cone or at least the wall could be below be hemispherical.
- Container 1 is below closed by a bottom 5, in the center of which Swamp 7 is formed, which is also a cylindrical or have a conical or hemispherical shape can.
- the container 1 can be made of plastic, metal or Be made of concrete.
- An inlet line 9 opens tangentially into the upper region of the container 1.
- a helical guide in the form of a continuously narrowing channel 13 connects to the front end 11 of the inlet line 9.
- the channel 13 is designed as an L-shaped profile with a vertical leg extending at an acute angle to the wall 3, the horizontal leg of which is connected to the wall 3 of the container 1, for example welded or glued.
- the channel 13 extends over at least an angular range of 90 ° and ends at the height h 2 .
- the width of the channel 13 is preferably continuously decreasing.
- the end of the channel 13 is therefore below the mouth of the line 9, which is at the height h 3 .
- the gutter 13 can also have a U-shaped shape like a gutter. In any case, it should ensure that the liquid leaving the channel 13 at its end continues to flow on the wall 3.
- rib 15 Extends around the centrally arranged sump 7 a range of approximately 180 degrees or more rib 15 which extends in a spiral shape and protrudes from the bottom 5.
- the part closest to the axis A of the container 1 the rib 15 is located in the outer surface of the wall of the swamp 7 and extends from there with increasing Distance and preferably increasing height spiraling from the axis A over half the circumference of the container 1.
- a sludge suction line 17 leads from the sump 7 out of the container 1. As shown in FIG. 2, the sludge suction line 17 can protrude centrally into the sump 7, lead upwards and be closed by a valve 19. The line 17 can also lead from the sump 7 downwards (not shown) or laterally. The suction line 17 can be connected to a pump, not shown, if the drain cannot take place on a slope. Alternatively, according to the embodiment in FIG. 5, an overflow line 22 can lead out of the sump 7, the outflow 24 of which ends at height h 3 . As soon as the container 1 is full, an outflow via the line 22 begins and at the same time the sludge is removed from the sump 7.
- a liquid removal line 23 ends at a short distance from the bottom 5, with which the liquid freed from solids can be suctioned off.
- the end of the extraction line 23 is preferably provided with a strainer 25. On the one hand, this prevents solid bodies from being sucked in, and on the other hand this increases the suction area and reduces the build-up of a suction flow directed towards the end of the removal line 23.
- the end of the extraction line 23 or the strainer 25 is below the minimum filling height h 1 .
- the container 1 is within a volume much larger space or tanks 31 used.
- the sendiments remain in the sump 7 of the container 1 and can this be removed periodically.
- the channel 13 is through a tube 35 formed, the helical along the wall 3rd is led.
- apex S that is Cut tube 35 at intervals so that openings 37 arise through which the sediment-free water emerges can if the water level in tank 1 rises and the lower pipe end exceeds.
- the tube 35 ends on the Container bottom 5.
- the inflowing liquid for example rainwater from roofs and squares, flows through line 9 into container 1 and reaches wall 3 of container 1 via inclined channel 13 and with ever increasing flow velocity.
- the higher the flow velocity of the liquid the greater
- the amount of liquid introduced causes the entire contents of the container to rotate in a clockwise direction. The greater the inflow and the smaller the liquid level in container 1, the greater the rotational speed.
- the constant circulation of the container contents improves the quality of the liquid and the shelf life.
- Solids which settle on the bottom (bottom 5) of the container 1 are successively transported to the center by the rib 15 and reach the sump 7. There is no longer any whirling up within the sump 7 and the solids can pass through the sludge discharge line 17 and / or the overflow line 22 can be removed from the sump 7.
- the solids can be removed from the sump 7 continuously or periodically.
- the solids are always removed when the container overflows.
- the situation is similar in the case of the tubular trough in FIGS. 9 to 11.
- the incoming liquid flows downward with increasing speed and can be removed near the ground, separately from the solids.
- the sediment-free liquid exits through the opening 37 closest to the surface; the sediments slide further down the tube 35 into the sump 7.
- the removal of the liquid essentially freed from solids takes place through the liquid removal line 23. The removal is possible continuously or periodically.

Abstract
Description
Es sind auch bereits sehr aufwendige ausgeklügelte Schmutzausscheidevorrichtungen bekannt (EP-A1 0 448 282), bei denen die mit Festkörpern beladene Flüssigkeit durch verschiedene Kammern oder Kammerteile eines Behälters geführt werden. Diese bekannten Vorrichtungen eignen sich jedoch nur für unter Druck stehende Behälter, nicht jedoch für solche, die im Prinzip drucklos arbeiten, wie dies üblicherweise bei Regenbrauchwasseranlagen der Fall ist. Deren Aufbau ist zudem teuer in der Herstellung und im Unterhalt.
Eine weitere besonders vorteilhafte und kostengünstige Ausgestaltung der Erfindung umfasst anstelle der V-förmigen Rinne ein schraubenlinienförmig entlang der Wandung des Behälters geführtes Rohr, das in Abständen im Scheitel Austrittsöffnungen für das Wasser aufweist, d.h. abschnittweise als halbkreisförmige Rinne ausgebildet ist.
- Figur 1
- einen Querschnitt durch den Behälter längs Linie I-I in Figur 2,
- Figur 2
- einen Längsschnitt durch den Behälter längs Linie II-II in Figur 1 und
- Figur 3
- eine vergrösserte Darstellung des Querschnitts der Rinne im Schnitt II-II in Figur 1,
- Figur 4
- eine vergrösserte Darstellung der Rinne an deren auslaufseitigem Ende X,
- Figur 5
- einen Längsschnitt durch den Behälter in einer Ausführungsform mit einer seitlich aus dem Sumpf wegführenden Überlaufleitung,
- Figur 6
- einen Grundriss einer weiteren Ausgestaltung der Erfindung, bei der der Behälter innerhalb einem wesentlich grösserem eckigen Raum eingesetzt ist,
- Figur 7
- einen Grundriss einer weiteren Ausgestaltung der Erfindung, bei der der Behälter innerhalb einem wesentlich grösserem runden Raum eingesetzt ist,
- Figur 8
- einen Querschnitt längs Linie VIII - VIII in Figur 7,
- Figur 9
- einen Grundriss durch einen Behälter mit einer Rinne, die aus einem schraubenlinienförmig verlaufenden Schlauch gebildet wird,
- Figur 10
- einen Rinnenabschnitt in Seitenansicht im Bereich A in Figur 9,
- Figur 11
- einen Querschnitt durch die Rinne in Figur 9 längs Linie XI - XI.
Alternativ kann gemäss der Ausführungsform in Figur 5 aus dem Sumpf 7 heraus eine überlaufleitung 22 wegführen, deren Ausfluss 24 auf der Höhe h3 endet. Sobald der Behälter 1 voll ist, beginnt ein Abfluss über die Leitung 22 und gleichzeitig wird der Schlamm aus dem Sumpf 7 abgeführt.
Analog sind die Verhältnisse bei der rohrförmigen Rinne in den Figuren 9 bis 11. Die eintretende Flüssigkeit fliesst mit zunehmender Geschwindigkeit nach unten und kann in Bodennähe, getrennt von den Festkörpern entnommen werden. Steigt im Behälter 1 der Wasserspiegel, so tritt die sedimentfreiere Flüssigkeit durch die der Oberfläche am nächsten liegende Öffnung 37 aus; die Sedimente gleiten im Rohr 35 weiter nach unten in den Sumpf 7.
Die Entnahme der von Festkörpern im wesentlichen befreiten Flüssigkeit erfolgt durch die Flüssigkeitsentnahmeleitung 23. Die Entnahme ist kontinuierlich oder periodisch möglich.
