Definitions
- the invention relates to a system for separating light liquids from water mixed with such liquids in the form of a liquid-tight container with a level at the container outlet for the clear water or above the inlet for the water mixed with light liquid and a liquid-tight collecting vessel integrated in the container for the in light liquid floating on the container with an access for the light liquid at the level of the container inlet or below it and a suction pipe for light liquid accumulated in it from the bottom area of this vessel, with an inlet side upstream of the clear water outlet, starting from the bottom area of the container and passing into the outlet can be closed under the action of a floating body which can be immersed in the light liquid floating on the clear water into its closed position en riser pipe (DE-S 43 04 867).
- the invention is therefore based on the need for a more cost-effective solution that is also easy to maintain.
- the riser pipe passing into the bellows extends through an area which is delimited in a liquid-tight manner from the sedimentation area of the container and is upstream of the clear water outlet and is then also penetrated by the linkage provided at its free end with the closing body for the riser pipe, this area also expediently also Head through an
- REPLACEMENT B ⁇ (RULE 26) shielding is limited, which is again designed in the manner of a bellows coming liquid-tight against the rods.
- the solution according to the invention is structurally less complex than solutions according to the prior art. It then also proves to be extremely easy to maintain, since the moving parts of the system, in particular the locking mechanism for the riser, are easily accessible. It also proves to be advantageous here that the area of the clear water outlet can also be secured in a desirable manner against the inflow of approximately gushing surfaces.
- the water mixed with light liquid is introduced for the purpose of separating the light liquid from the water.
- the supply of the water mixed with light liquid takes place through the inlet 121 (arrow A) merging into a downpipe 122.
- the outlet for the clear water lying lower than the inlet 121 is designated by 123.
- On the bottom 124 of the container 12 sits the collecting vessel 21 for the light liquid floating in the container 12, which is provided overhead with an access 211 for the light liquid located below the container inlet 121 for the water to be cleaned but above the outlet 123 for the clear water which merges into a down pipe 212 reaching into the bottom region of the collecting vessel 21.
- a ventilation pipe 213 ensures that the accumulation vessel 21 is filled as much as possible with light liquid while avoiding backflow, the maximum permissible filling being signaled by the fill-level indicator 214.
- the collecting vessel filled with light liquid is disposed of via the suction line 216 (arrow B).
- the clear water outlet 123 is preceded by a region 31 which is liquid-tightly shielded (311, 311 ′) from the sedimentation region 126 of the container 12 and into which a riser pipe 32 extending from the sedimentation region 126 of the container 12 extends, into a bellows 321 passes from which the clear water flowing through the riser pipe 32 and the bellows 321 flows over the head (322) into the shielded area 31 and thus to the outlet 123 for the clear water (arrows C, C).
- the bellows 321 is suspended from a linkage 33 passing through the riser pipe 32 and the bellows 321 (323).
- the linkage 33 in turn is suspended (331) on the arm 341 of a (343) rocker 34 installed on the container 12, the other arm 342 of which carries a floating body 36 which rests on the liquid mixture entered in the container 12 and is immersed in the floating light liquid.
- the free end of the rod 33 passing through the ascending pipe 32 and the bellows 321 is provided with a closing body 37 for the ascending pipe 32 which, with increasing layer thickness of the light liquid floating in the container 12, decreases (arrow D '), a pivoting of the rocker 34 in the sense of the arrow D causing floating body 36 taken from the linkage 33 against the riser 32 (arrow D "), which closes the riser.
- the level of the bellows overflow 322 in the initial position of the rocker 34 shown in the drawing defines the normal filling of the container 12.
- Additional protection against contamination of the clear water area by gushing surface water is provided by supplementing the circumferential shield 311, 311 'of the area 31 upstream of the clear water outlet 123 by an additional shield 311 "through the rod 33, which then also resembles a type Bellows is formed, the linkage is liquid-tight.
