Definitions
- the subject is a device for separating the Solids from liquid-solid mixtures according to Preamble of claim 1 as e.g. from the Document EP-A-0 448 282 is known.
- 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 elaborate, sophisticated dirt separating devices are also already known, 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 a 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, that is to say is formed 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. 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 means 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 leg extending at an acute angle to the wall 3 and a horizontal leg 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 is intended to ensure that the liquid leaving the channel 13 at its end continues to flow on the wall 3.
- the centrally arranged sump 7 extends over a range of approximately 180 degrees or more rib 15 extending in a spiral shape and protruding 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 out of the sump 7 out of the container 1.
- 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.
- an overflow line 22 can lead out of the sump 7, the outflow 24 of which ends at the level 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 sucked 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 trough 13 is through a tube 35 formed, the helical along the wall 3rd is led.
- apex S that is Cut pipe 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 exceeds the lower pipe end.
- 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 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 conveyed to the center by the rib 15 and reach the sump 7. Swirling within the sump 7 no longer takes place 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 liquid that flows in 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 down tube 35 further down into the sump 7.
- the liquid, essentially freed from solids, is removed through the liquid removal line 23. The removal is possible continuously or periodically.
