Definitions

  • the invention relates to a method for operating a waste water lifting plant, according to which waste water contaminated with solids is passed through a solids collection tank with at least one separating sieve arranged in its interior, after which the solids are retained in the solids collection tank at the waste water inlet and pre-cleaned waste water via a connecting line of a pump and finally a liquid collection tank, and after which the pre-cleaned waste water reaches the liquid collection tank on the one hand via the pump and on the other hand via a bypass line connected to the connecting line.
  • Wastewater lifting plants are generally used to lift inflowing wastewater to a certain level, for example for further treatment in a wastewater treatment plant. Since the waste water is contaminated with more or less large bulky substances or solids, large pumps have initially been used in the past, but they are not convincing in terms of cost and efficiency. For this reason, the bulky matter collection tank upstream of the pump ensures that the bulky matter is held back inside with the help of the separating sieve. As a result, only pre-cleaned waste water reaches the pump and is stored in the liquid collection tank.
  • a filter device is provided outside the liquid-collecting container.
  • the filter device is arranged in front of the pump in a filter box provided with a closable opening.
  • a filling bypass is connected to the filter box, through which the liquid collection tank can be filled.
  • the pre-cleaned waste water reaches the liquid collection tank via the pump.
  • the filling bypass is open while the liquid collection tank is being filled, i.e. when the waste water is inflowing.
  • the filling bypass is blocked while the liquid collection tank is being emptied, ie during the pumping process.
  • the known filling bypass is designed as a funnel at its upper end opening into the filter box.
  • the obturator is a light, floating ball which, due to its buoyancy, rests against a limit at the top of the funnel.
  • Such a ball as a shut-off device is disadvantageous insofar as, for example, smaller solids or blocking materials that are unchanged in the pre-cleaned waste water can lead to problems during the closing process. In addition, caking, calcification, etc. are often observed, which also call into question the functionality. If within the framework of EP 1 108 822 B1 also with a local bypass in shape a derivation is worked parallel to the connecting line, a shut-off device is already missing.
  • a bypass line with associated obturator is by and large also in the FR 752 942 described.
  • the bypass line is connected to the connecting line to the liquid collection container in front of an associated pump.
  • a shut-off valve is also provided in the bypass line.
  • the DE 195 43 123 C1 discloses a generic sewage pumping station.
  • the DE 33 33 883 A1 shows a container for a sewage pumping station with a pressure pipe arranged inside the container wall.
  • the invention is based on the technical problem of further developing a method for operating a sewage pumping station in such a way that functionally reliable operation is ensured, taking into account a structurally simple structure.
  • a pivoting flap is provided in the connecting line, which closes the connecting line except for a flushing cross-section when the waste water is fed in and opens the bypass line, and during the pumping process opens the connecting line and closes the bypass line.
  • the subject matter of the invention is also a correspondingly designed sewage lifting plant, as described in claims 9-12.
  • a bypass line is therefore initially used, which is connected to the connecting line between the solids collection container and the pump, and in contrast to the teaching according to FR 752 942 is not upstream of the pump.
  • a comparable topology as in the generic state of the art after EP 2 581 508 B1 realized.
  • a separate filter box is not provided as it were in the connecting line. Rather, according to the invention, the filter box or the separating sieve is located inside the bulky material collection container.
  • the design can be made according to the invention in this context such that the separating screen can be inserted into the bulky material collection container via a closable opening in the bulky material collection container and can be removed from it again, for example for cleaning purposes or for replacement. If, in addition, the solids collection tank and the pump are also arranged outside of the liquid collection tank, a sewage pumping system that is easy to clean and maintain overall is made available.
  • the invention uses a pivoting flap in the connecting line as the shut-off element.
  • the pivoting flap does not close the connection line completely at the waste water supply line or at the waste water inlet, but except for a flushing cross section.
  • This means that the flushing cross section is generally defined at the edge of the pivoting flap, which is automatically set by a distance between the (closed) pivoting flap on the one hand and an inner wall of the connecting line in this area on the other hand.
  • this flushing cross-section ensures that the pivoting flap is flushed at the edge at least when the waste water is inflowing, so that caking, calcification, etc., can practically not adhere to this point.
  • the pivoting flap in the connecting line that closes the connecting line at the waste water inlet up to the flushing cross section ensures that the main part of the waste water flow is transferred directly and bypassing the pump via the bypass line into the liquid collection tank.
  • the design is also and advantageously such that the previously described waste water flow connected to the waste water inlet and a pump flow connected to the pumping process are dimensioned essentially the same.
  • This dimensioning rule means that between the wastewater flow and the pump flow, for example, a volume deviation is observed within a given time that is less than 20%.
  • the waste water flow connected to the waste water inlet can be 10 l/s.
  • a pump flow of approx. 11-12 l/s is observed, so that the wastewater flow and the pump flow are measured essentially the same if volume deviations within the specified time, in this case one second, of less than 20% are used as a benchmark creates.
  • the volume deviation is measured at a maximum of 20% (12 l/s to 10 l/s).
  • a specific and specified pump is usually assumed. As a result, the pumping flow is more or less fixed, which slightly exceeds the waste water flow as described with regard to the pumped pumped quantity.
  • the waste water flow which is to be measured essentially the same way, can now be set up by the geometric design of the connecting line as well as the bypass line in connection with the pivoting flap and the flushing flow predetermined by it in such a way that compared to the pump flow only a volume deviation of less than 20% is observed.
  • This dimensioning rule ensures that pressure fluctuations or “impacts” within the liquid-collecting container that have often been observed up to now in the prior art and in practice are almost completely avoided.
  • the design is usually such that the sewage lifting plant according to the invention is equipped with two solids collection tanks and two associated pumps, which are each connected to the liquid collection tank. At the wastewater inlet, the pre-cleaned wastewater usually flows through one of the two pumps, while the other pump is pumping. Since the waste water flow and the pump flow are dimensioned essentially the same in this process according to the invention, taking into account the criteria specified above, a liquid level within the liquid collection container remains essentially the same or is only subject to minor fluctuations.
  • pivoting flap is connected to a flange of the bypass line and/or a flange of the connecting line and/or a flange of a flap socket via a joint at the base.
  • Swivel flap connected to the flange of the flap stub.
  • the flap connector in question can advantageously be used as a 3-way connector in the connecting line.
  • this allows the bypass line to be connected via a branch of the flap connector and coupled to the branch.
  • the flap connector including the pivoting flap located therein, works advantageously in the manner of a 3-way valve.
  • the pivoting flap ensures that the connection line is closed down to the flushing cross-section.
  • the bypass line is open.
  • the connecting line is (completely) opened and the bypass line (completely) closed.
  • the scavenging flow mentioned above is only observed in the waste water inlet when the pivoting flap closes the connecting line except for the scavenging cross section—that is, not completely.
  • the pivoting flap is usually positioned at an angle in the connecting line at the waste water inlet.
  • the inclined position of the pivoting flap at the waste water inlet is generally approx. 10° to 30° compared to the horizontal. This means that the tilted pivoting flap encloses an angle in the range of approx. 10° to 30° with the horizontal.
  • the inclined position ensures that the pivoting flap can swing open immediately during a subsequent pumping process and no caking is observed due to deposits.
  • the pivoting flap is usually limited with the aid of at least one stop with regard to its inclined position.
  • the stop is generally provided inside the flap connector or generally inside the connecting line.
  • the stop is designed in such a way that the flushing cross-section, which has already been discussed several times, remains with the waste water inlet and in the closed position of the pivoting flap.
  • the connecting line according to the invention has a bulge in the area of the pivoting flap, which is closed when the waste water is fed in, and which bulges which determine the rinsing cross section. Since the pivoting flap is generally arranged in the interior of the flap connection, the flap connection in question is regularly equipped with the bulge defining the flushing cross section in the area of the pivoting flap, which is closed when the waste water is fed in. Either way, the flap connector, including the pivoting flap located therein, generally works in the manner of a 3-way valve, as has already been described in detail above.
  • a method for operating a sewage pumping station which provides functionally reliable operation even over long periods of time, taking into account a compact and cost-effective design.
  • the pivoting flap is closed. Since the flushing cross-section remains during the closing process, the shut-off valve is flushed at the same time and the pump located behind it in the inflow direction as well as a supply line to the liquid collection tank are flushed.
  • the pivoting flap can be pivoted directly during a subsequent pumping process by the pre-cleaned sewage flowing against it and being pumped with the help of the pump, such that the connecting line is opened and the bypass line is closed. This is where the main advantages can be seen.
  • a sewage pumping station is shown. First of all, this has an inlet 1 for waste water, which transfers the waste water to two solids collection containers 4 via an inlet distributor 2 and a feed line 3 in the exemplary embodiment.
  • the sewage lifting plant is designed symmetrically and has two solids collection tanks 4 and two additional discharge lines or connecting lines 5, via which the waste water pre-cleaned with the help of the solids collection tank 4 reaches an associated pump 6 in each case.
  • the solids collection tank 4 or the two solids collection tanks 4 ensure that the waste water which flows in overall via the inlet 1 and the inlet distributor 2 and is contaminated with solids is freed from the solids or solids which are in the associated solids collection tank 4 remain.
  • the wastewater pre-cleaned in this way then passes via the discharge line 5 or connecting line into the pump 6 or via a bypass 7 directly into a liquid collection tank 8.
  • the pre-cleaned wastewater flowing through the respective pump 6 also passes through a supply line 9 into the liquid -Collection tank 8. The inflow of the waste water corresponds to this.
  • the pre-cleaned waste water is now sucked in from the liquid collection container 8 via the supply line 9 by the pump 6 and pushed through the discharge line or connecting line 5 into the solids collection container 4 .
  • the pre-cleaned waste water takes the solids retained in the solids collection tank 4 and transfers the waste water via a pressure line 11 to another plant or generally to further treatment.
  • the bulky substances are released from the bulky substance collection container 4 and flushed into the pressure line 11 with practically no resistance.
  • both the pump 6 and the respective solids collection container 4 in connection with the discharge line or connecting line 5, the supply line 9 and finally the bypass line 7 are arranged overall outside of the liquid collection container 8 and are therefore easily accessible.
  • the separating screen that is present inside the bulky material collection container 4 and is not expressly shown can be removed and reinserted via this closable opening. This allows maintenance work to be carried out on the separating screen or an exchange to be carried out.
  • Pivoting flap 12 is provided in the connecting line 5 according to the exemplary embodiment.
  • the pivoting flap 12 is located inside a flap connector 13.
  • the flap connector 13, including the pivoting flap 12 located therein, works in the manner of a 3-way valve, as will be explained in more detail below.
  • the flap connector 13 is inserted into the connecting line 5 as a 3-way connector.
  • the flap connector 13 is coupled to the bypass line 7 via a branch.
  • the pivoting flap 12 in the connecting line 5 or in the flap connector 13 used in the connecting line 5 closes when in the 2 Wastewater inlet shown, the connecting line 5 to a rinsing cross section 14.
  • This rinsing cross section 14 arises as an annular space or annular cross section in that the swivel flap 12 in the 2 shown closed state compared to the inner wall of the flap connector 13 is spaced.
  • the connecting line 5 or the flap connector 13 provided in the connecting line 5 has a bulge 15 that defines the flushing cross section 14 in the area of the pivoting flap 12 that is closed when the waste water is fed in.
  • the pre-cleaned waste water sucked in with the help of the pump 6 via the supply line 9 from the liquid collecting tank 8 ensures that the pivoting flap 12 moves into the position after the 3 is transferred.
  • the pumping process ensures that the connecting line 5 or the flap connector 13 looped into the connecting line 5 is opened and, on the other hand, the bypass line 7 is closed with the aid of the pivoting flap 12 .
  • This is necessary so that the pre-cleaned waste water is not fed back into the liquid collection container 8 via the bypass line 7, but instead flows completely through the solids collection container 4 during the pumping process.
  • the pre-cleaned waste water can detach the solids retained in the solids collection tank 4 from the separating screen and flush the waste water into the pressure line 11 .
  • the pivoting flap 12 is connected to a flange of the flap socket 13 via a base-side joint 16 in the exemplary embodiment. Consequently, the flap connector 13 with the pivoting flap 12 arranged in an articulated manner therein can be built into the connecting line 5 as a finished built-in module and connected to the bypass line 7 as shown. In addition, the flap connector 13 in question can be easily removed and cleaned, for example, if necessary.
  • the pivoting flap 12 is, without limitation, one that may have a metallic core and an outer plastic sheath, as is known in FIG 4 takes.
  • the foot-side joint 16 ensures in this context that the butterfly valve 12 when comparing the 2 and 3 positions shown can easily and wear-free assume.
  • the butterfly valve or pivoting flap 12 when in the 2 waste water inlet shown in the connecting line 5 inclined.
  • the indicated horizontal H is measured at values of approx. 10° to 30°.
  • the stop may be a support ring for the pivoting flap 12 provided in the flap socket 13 on the inside wall, such as in particular the 4 makes clear. This support ring is realized in the area or subsequent to the bulge 15 .
  • the support ring in conjunction with a nose-like projection on the underside of the pivoting flap 12, overall defines the flushing cross section 14 that is set.
  • other stops are also conceivable, as long as the flushing cross section 14 required for the waste water inlet and necessary according to the invention remains.
  • the design is such that a waste water flow connected to the waste water inlet and a pump flow connected to the pumping process are dimensioned essentially the same.
  • This can easily be done by appropriately selecting the geometry of the connecting line 5, the bypass line 7, the pump 6 and the flap connector 13 and the pivoting flap 12, as well as by selecting the pump 6 with the appropriate flow cross section reach and adjust.
  • practically no pressure peaks are observed inside the liquid-collecting container 8, as in the prior art, so that its mechanical stability is permanently increased.
