Definitions
- the invention relates to a sewage lifting plant according to the Preamble of claim 1.
- Such sewage lifting plants are by DE-PS 21 15 106 and by DE 36 07 353 C2 known.
- the purpose of these wastewater lifting plants is that for example, to absorb wastewater from residential complexes and from a low level via a pressure pipeline to a higher level in the sewer system pump.
- the wastewater flows during the filling process first in a bulky material storage room, in which the bulky substances carried in the wastewater through partition flaps are retained, with each divider one Flap opening is assigned.
- the flap opening not completely through the separating flap, but only partially closed.
- the precleaned free of impurities Wastewater then flows through the remaining one free part of the flap openings in a collection container.
- the Pump creates a flow to remove the water from the reservoir to promote in the pressure pipeline, and further It has already been described above that this is in the bulk material collection room retained bulky substances in the Pressure pipeline to be flushed. It can be in the bulk material collection room turbulence in the flow occurs with the result that those located in the bulky material collection room Solids spin in the swirl zone and stay there and not completely in the Pressure pipeline to be promoted. After completing the The emptying of the collecting container can therefore always There are still solids in the bulk material collection room.
- the object of the invention is functional reliability to improve a wastewater lifting plant and Avoid blockages in the bulk material collection area.
- the invention is based on the knowledge that the known wastewater lifting plant the flow of wastewater regularly when emptying the collection container the lower flap opening in the bulky material collection area occurs, and that practically no share of the flow through the upper flap opening into the bulk material collection area reached. This will form in the bulk material collection area different in the area of the two flap openings different in the area of the two flap openings Express, being in the area of the upper flap opening there is a vacuum. This pressure difference leads to the turbulence of the flow within the Bulky material collection room on the way to the pressure pipeline, the swirls being those described above Cause disadvantages.
- the invention sees between the collection container and the Bulky material collecting means through which the Flow of the waste water (15) when emptying the Collection container (30) influenced and divided in this way is that also through the upper flap opening (38) predetermined defined proportion of waste water (15) in the Bulky material collecting space (20) flows, so that none Turbulence of the flow in the bulk material collection room (20) occur and pressure differences between the top Flap opening (38) and the lower flap opening (40) are largely avoided.
- a division has proven particularly expedient, at which about 30% of the flow through the upper and about 70% of the flow through the lower flap opening flow when emptying the collection container.
- a flow baffle located in the chamber educated.
- the latter is preferably on top of the lower flap opening and extends at an angle into part of the common chamber.
- the waste water 15 flows through an inlet line 16 inclusive of the carried bulk materials 17 via a Distributor 18 in the bulky material collection rooms 20.
- This The filling process is in the right part of the drawing next to the Line of symmetry 48 illustrated.
- the wastewater 15 arrives with the barrier substances 17 in the right bulky material collecting space 20, which - as well as the left bulky material collecting space 20 - a floating ball 32 as Shut-off device includes, its function below is described.
- the bulky material collection rooms are located within a housing 12 of the sewage lifting plant 10, and the housing 12 has a ventilation opening 14 for the ventilation.
- partition flaps in the bulky material collecting space 20 22 each with an associated upper flap opening 38 and a lower flap opening 40.
- the partition flaps 22 lie on upper spacers 42 and lower Spacers 44, which are rib-shaped in the area of the flap openings 38 and 40 extend (see Fig. 2). In this way, the two flap openings 38 and 40 largely closed during the filling process, so that the Bulky substances 17 through the partition flaps 22 in the bulky material collecting space 20 are held back.
- the pre-cleaned Non-toxic waste water flows through the remaining one Part of the flap openings 38 and 40 via a connecting line 24 and a flap assembly 36 in the collection container 30th
- the flap arrangement 36 ensures that when Filling the collecting container 30 the pre-cleaned wastewater does not have to take the route via the pump 26, but can flow directly into the collecting container 30.
- valve assembly 36 gives way to the pump 26 free when the collection container 30 is emptied, so that then the flow can flow through the pump 26.
- FIG. 2 shows a cross-sectional view as an exemplary embodiment the invention a bulky material collecting space 20, which in any case ensures that the detained Bulky substances when emptying the collection container be completely flushed into the pressure pipeline.
- the barrier material collecting space 20 has a housing 54 with an upper inlet opening 56 for the with bulky materials contaminated wastewater.
- An outlet opening 58 serves as a connection to the pressure pipeline 34, and via a connection opening 60 becomes a connection to the connecting line 24 for connection to the pump 26 or the collecting container 30 manufactured.
- the upper wall is located above the connecting wall 70 Flap opening 38, and below the connecting wall 70 the lower flap opening 40 is arranged.
- partition flaps 22 see FIG. 1 not here shown.
- the flow rate can be divided between the two Influence flap openings 38 and 40.
- the size too the flap openings 38 and 40 and the dimensioning the common chamber 52 can influence the division of the flow rate. It should be in everyone In case such a division is sought that too wanted through the upper flap opening 38 a defined Proportion of waste water flows into the bulky material collecting space 20.
- the flow rate is divided into a predetermined and defined way on the upper flap opening 38 and the lower flap opening 40.
