Height adjustment unit for the floating fabric hood

The innovation concerns a height-adjustable ^ Schwiaasstoffabzug for the flotation of sewage treatment and / or purification systems.

Such lengths of black diamond serve to separate the waste water accruing floating matter, the raw wastewater being first fed to the floating matter via an E ^ ker, there for a certain dwell time, usually 2-5 minutes, and then the downstream wastewater clarification or cleaning system is supplied. During this dwell time, the floating matter carried along with the wastewater can become collect at the water surface of the swimming pool. They are then drawn off via a floating substance discharge line and mostly added to the sludge trap of the downstream sewage treatment plant. Before * here they are pumped onto drying beds or conveyed to a sludge silo.

The innovation is based on known constructions in which the inlet opening of the floating material discharge line of the Swimming material lengths only with a rubber ball or one

Rubber stopper is closed. When the floating matter builds up ± 22 SwimmetOffang wp-rdpri this by means of a chain or aa Rope raised to the inlet opening of the floating matter discharge line to expose. The inlet opening is expanded like a funnel or trough, so that the rubber ball or the rubber stopper after the removal of the floating substances should slide in front of the inlet opening again. In practice, however, it has been shown that in this way a faultless Sealing of the floating substance discharge line cannot be achieved again, as the sealing surfaces become strong over time pollute. This means, however, that bsi also seem more closed A not inconsiderable amount of raw wastewater was drawn off through this line and fed to the sludge trap of the downstream sewage treatment plant. However, this can reduce the sludge cycle and the removal of excess sludge the sewage treatment plant can be severely disturbed, which of course leads to an impairment of its puncture ability leads.

In addition, the known construction has the disadvantage that the chain to which the rubber ball or rubber stopper is attached are often very dirty from the floating substances having. For example, fat and oil tend to be attached to the chain. Among other things, the operation of the floating fabric trigger must be done by hand, the operating staff often complains about the un-

The innovation was therefore based on the task of

This goal is achieved by a height-adjustable Schwiminetoffabzug for the Schwimmstoffang of sewage treatment and purification systems, which is characterized in that one with a Collecting funnel provided pipe socket is fastened pivotably up and down by means of joints in a floating material discharge line, with a Bellows is provided and attached to the upper edge of the collecting funnel a chain used to adjust the height is.

So that the pipe socket provided with the collecting funnel has a sufficiently large pivoting range, the floating material discharge line must either be expanded in the form of a funnel in the area of the pivot point or have a correspondingly larger diameter than the pipe socket.

Due to the pivotability of the provided with the collecting funnel Rohretutzena is given the possibility of the floating sludge suction due to fluctuations in the water level in the floating material adapt. The Sanunel funnel serves as a collecting device for the Schwin · toffe. There is also the possibility of lowering the Samael funnel to below the water level

to be able to derive bulky Schwiiamstoff. The Collection funnel at a certain height above the water level be fixed, creating a layer of floating material is made possible in the desired height.

The required sealing of the pivot point is carried out by the bellows, which are preferably made of rubber or plastic is manufactured and at the same time the necessary adjustable

speed allows.

The desired height of the floating material discharge is set using the chain attached to the upper edge of the collecting funnel, which is hung on the other side on the edge or on the railing of the floating material. Their length is chosen so that immersion in the floating matter cannot take place.

Figure 1 shows a side view of the claimed device. You can see the pipe socket 1 with the attached to it Collecting funnel 3. The pipe socket is by means of the joints attached in the floating material discharge line 4 up and down pivotable. This means that there is a sufficiently large swivel range is, the floating substance discharge line must either have a larger diameter in the area of the pivot point than the pipe socket, as shown in the present Figure 1

is posed. Or the floating material discharge line must be expanded in a funnel-shaped manner in the area of the pivot point. The bellows, which ensure the necessary sealing, is fastened to the pipe socket 1 and to the floating material discharge line 4 by means of the clamping rings 6. The chain 7, which is attached to the upper edge of the collecting funnel 3 and is used to adjust the height of the floating material discharge, can also be replaced by a cable or the like. In the illustration, the pipe socket with the collecting funnel is just at the uppermost end point of its pivoting range. By appropriate adjustment of the chain 7 can be moved in the direction dee rl eiles down.

Figure 2 shows a cross section through the claimed device in the area of the swivel axis.

The claimed device provides a significant simplification and a significantly better control option of the Schwiqnstoffabzuges achieved. Simultaneously were The hygienic conditions for this are significantly improved and disruptions in the operation of the downstream sewage treatment plant are avoided.
