Definitions
- the invention relates to a wastewater lifting plant, comprising at least one bulk material collecting container with at least one separating sieve arranged in its interior for wastewater and wastewater loaded therewith, wherein the separating sieve subdivides the bulk substance collecting container into a pulp-contaminated and a pulp-free region, and wherein the separating sieve is pivotally connected via a hinge to a flange of the bulk material collecting container.
- the separation screen has a pivotable mounting inside the bulk material collection container.
- the dividing screen on the hinge to the
- the hinge can also be designed as a film hinge or a hinge, which is provided by a flexible band.
- the flange generally designates a hinge attachment portion on or inside the bulk material collection container.
- a wastewater lifting plant of the structure described in the introduction according to DE 1 609 1 66 the procedure is such that the separating sieve is designed as a rake with a non-return flap.
- the rake is covered by the check valve.
- the computing bars of the rake do not fill the entire cross-section of a connecting line.
- the rake can no longer be added by the barrier substances. This should be avoided operational interruptions.
- WO 2010/025852 A1 a wastewater lifting plant is described in which a connecting line with a combined shut-off / screening device is connected to the bulk material collecting tank.
- the shut-off / screening device is arranged in the interior of the bulk material collecting container.
- the dividing screen and the shut-off / screening device in question have an arrangement oriented essentially at right angles to one another.
- the solids are first separated from the wastewater or from a fluid medium before this fluid enters the pump.
- the bulk material collection container with the arranged in its interior separation screen. Only the barrier-free wastewater and consequently pre-cleaned wastewater is transferred in this context in a the bulk material collecting tank downstream liquid collecting container.
- the pre-treated wastewater can now be easily processed by means of said pump and in particular be raised to the desired level. In this process, at the same time the previously retained by the separation sieve solids are released from this again.
- the invention is based on the technical problem of further developing such a wastewater lifting plant in such a way that the cleaning of the separating sieve takes place flawlessly and as completely as possible by backwashing with, in particular, pre-treated wastewater.
- the invention proposes in a generic wastewater lifting plant, that the separating screen at least one outward, d. H. towards the edge area, has opened opening.
- the hinge-side edge region of the dividing screen is formed like a comb.
- the invention initially assumes that the separating sieve dividing the bulk material collecting container is pivotally connected via the hinge to the flange in the interior of the bulky substance collecting container. Consequently, in conjunction with the flange, the separating screen connected to the flange by the hinge ensures that the bulk material collecting container is subdivided, as described, into the restricted material and the impermeable-free region.
- the invention provides that the separation screen at least in the hinge-side edge region has at least one outwardly open aperture, for example is formed comb-like in the hinge-side edge region in question.
- the invention is based on the recognition that the hinge-side edge region in question is primarily intended for the conclusion or the subdivision of the bulk material collection container through the separation screen provides.
- the hinge-side edge region is usually at a sealing region of the bulk material collection container, in the simplest case on its inner wall.
- this sealing area is equipped with the opening outwardly open, any backfilling of the separating screen any stripping adhering to the dividing fiber or elongated solids are stripped as it were from the hinge-side edge region of the separating screen through the flow.
- the fibers can no longer be retained by the separating sieve as a result of the opening which is open towards the outside.
- the separation screens which are consequently arranged one behind the other in the flow direction, can be designed in such a way that the openings are offset relative to one another. Usually, however, one will work with only one screen to keep the costs as low as possible and avoid soiling. Here are the main benefits.
- the hinge-side edge region typically designates the edge region of the separating screen which lies opposite the hinge for the pivotable connection of the separating screen to the flange. Because the hinge is mostly attached to the flange inside the Bulk-collecting container is connected to the head side of the separating screen, the hinge-side edge region of the separating screen corresponds to its foot, which rests in the course of the inflow of contaminated wastewater at the sealing area of the bulk material collection container or its inner wall.
- the individual longitudinal slots between the comb-like webs in the hinge-off edge region of the separating screen are all open to the outside according to an advantageous embodiment.
- solids of a certain size are retained, namely those which can not pass the longitudinal slots of their diameter.
- the opening of the longitudinal slots towards the outside in the hinge-off edge area on the other hand ensures that when rinsing the separating screen, any fibers or elongated barrier materials are stripped from the separating screen then at least slightly opened and lifted off the sealing area on the bulk material collection container, namely by the rectified flow. tion.
- the comb-like webs are generally equidistant, that is equally spaced, arranged to each other. This is done for the reason to provide the screenings to be retained in each case the same screen conditions.
- the bulk material collecting container is usually designed as a hollow cylinder.
- the separating sieve divides the hollow cylindrical substance collection container into the substance loaded in the substance which is impermeable to substances and the substance without barrier, in connection with the flange, it is advisable to form the separation sieve in the manner of a circle segment to ellipse segments.
- the flange that is to say, the circular disc-segment-like flange and the likewise circular disc-segment-like to elliptical segment-like separating sieve describe together taken in front view regularly a circular disc, which is adapted to the diameter and the design of the hollow cylindrical bulk collection container or can be adapted.
- shut-off device In addition to the separating screen usually a shut-off device is connected to the flange. This shut-off device may take over a sieve function together with the separating sieve. Then the shut-off device is a combined shut-off / sieve device, as described in detail in WO 2010/025852 A1. This is not mandatory. It has proven useful if the separating screen is connected at an oblique angle compared to the sealing region or the inner wall of the bulk material collecting container via the hinge to the flange. That is, in the built-in depressurized state (installed state), the dividing screen is applied to the seal portion inside the barrier collecting container in consideration of the skew angle in question. In contrast, the separation screen is lifted during the backwashing and an associated pressurization of the sealing area. The skew angle is reduced here.
- a bypass is usually provided.
- the bypass is provided in the non-barrier area of the bulk material collection container. This can be done as a bypass with a correspondingly shaped flow baffle. This is of course not mandatory, because you can work just as well with a arranged outside of the bulk material collection container bypass or even without a bypass.
- the separating screen bearing flange, the dividing screen, optionally the shut-off device and the optional bypass form an insertable into the bulk material collection unit assembly.
- the flange can also be designed as a closure flange of the respective bulk material collection container or connected to such, so that the assembly in principle only with a further end flange (to the bulk material collection container) completes needs to be. As a result, any maintenance can be carried out very easily and the separation screen can be easily replaced if necessary.
- the separating screen is first lifted from its contact with the sealing area in the interior of the bulk material collecting container. On the other hand, this results in a defined passage between the hinge-side edge region of the separating screen and the sealing region in question on the casing or the inner wall of the bulk material collecting container for the prepurified waste water flowing through it.
- the separating screen according to the invention is equipped in the hinge-off edge region with at least one outwardly open opening, so that the rinsing operations described ensure that any fibers or generally longitudinally extended solids are stripped from the separation screen by the flow.

- the pre-treated wastewater passes via a discharge line 4 to a pump 5 and may be transferred from there into a liquid collecting container, not shown, and stored here.
- the dividing sieve 6 divides the bulk material collecting container 3 in a fabric contaminated area 3a and a non-barrier area 3b.
- the overall interpretation is such that the solids supplied with the wastewater via the feed line 1 are collected in the area 3a exposed to the barrier substance and retained by the separating sieve 6.
- the barrier-free area 3b largely freed from solids and is consequently promoted pre-treated wastewater by means of the pump 5.
- a relatively small circular pump with a small passage cross-section and reduced power can be used in comparison to pumps, which at the same time have to transport the solids.
- shut-off / screening device 7, 8 To the separating screen 6 still enters a shut-off / screening device 7, 8 added.
- the blocking / screening device 7, 8 in question is to be regarded as an option overall and is not absolutely necessary.
- the combined shut-off / screening device 7, 8 is composed of a shut-off flap 8 and a sieve 7 as a structural unit.
- the sieve 7 of the combined shut-off / sieve 7, 8 ensures - as the separation sieve 6 - that the Solids in the supplied via the feed line 1 wastewater in the contaminated area 3a of the bulk material collecting container 3 are retained.

- the two sieves 6, 7 With the help of the two sieves 6, 7, the solids are retained in the waste water fed through the inlet 1 in the contaminated area 3a of the bulk material collecting container 3. In principle, however, it is also possible to work at this point only with the separating sieve 6 to be described in more detail below.
- a flow guide plate 11 which ultimately assumes the function of a bypass 11, can then be seen.
- the bypass 1 1 is inserted into the impermeable area 3b of the bulk material collecting container 3 or arranged therein and manifests itself in the context of the embodiment of FIG. 1 as the correspondingly designed flow baffle 1 first
- the variant according to FIG. 4 shows a bypass 1 1 mounted outside on the bulk material collecting container 3.
- the shut-off / sieve 7, 8 as well as the bypass or the flow baffle 1 1 is basically unnecessary.
- the separating sieve 6 arranged in the interior of the bulky waste collecting tank 3 restrains the solids entrained in the waste water in the contaminated area 3a, whereas the pre-cleaned wastewater passes the separating sieve 6.
- the separating screen 6 is now connected pivotably via one or two hinges 12 to the already mentioned flange 10 of the bulk material collecting container 3.
- the flange 10 in the exemplary embodiment is an end flange or side flange of the bulk material collecting container 3, which is described in detail in FIG Figures 2 to 4 is shown.
- the flange 10 in question may be connected to an end flange 19 or form a structural unit.
- the separating screen 6 has at least at its hinge-side edge region 6a via an outwardly, d. H. to the edge region 6a out, open aperture 1 3. Otherwise, the separation screen 6 is formed plate-like and closed according to the embodiment. In most cases, the dividing screen 6 is a disk-like or circle segment-like metal plate with the at least one opening 13. Regularly a plurality of openings 13 are provided, which are arranged predominantly in the center of the separating screen 6.
- the hinge-side edge region 6a of the separating screen 6 is opposite to the hinge-side region 6b, as can easily be seen with reference to FIG.
- a plurality of apertures 1 3 are realized in this hinge-side edge region 6 a of the separating screen 6, which are each open to the outside.
- the openings in question 13 are longitudinal slots 13, which are found between each comb-like webs 14.
- the longitudinal slots 13 are all open to the outside, that is, the hinge-side edge region 6a of the separating screen 6 is pointed out.
- the comb-like webs 14 as well as the longitudinal slots 13 each equidistant, that is equally spaced, are arranged to each other.
- the longitudinal slots 13 and the webs 14 can not only run parallel to one another, but also have a beam-like alignment with one another.
- the separating sieve 6 is designed in the manner of a circular disc segment or ellipsoidal segment.
- the flange 10 is also a circular disc segment.
- the overall design is made so that the flange 10 and the separating screen 6 in supervision complement each other to a circular disc, which is used as a partition in the correspondingly hollow cylindrical trained bulk material collection container 3.
- the shut-off / screening device 7, 8 is connected to the Flange 10 connected, as well as the separation screen 6 also pivotally.
- a further hinge 15 is provided in this context (see Fig. 2).
- Slant angle ⁇ is connected to the flange 1 0 or the skew angle ⁇ is observed in comparison to the inner wall or a sealing region 1 6 of the bulk material collecting container 3.
- the skew angle ⁇ is typically less than 90 °.
- skew angle ⁇ of more than 20 ° is usually observed.
- An inclined angle ⁇ of less than 70 ° is preferred.
- Very particular preference is observed skew angle ⁇ in the range of about 30 ° to 55 °.
- the sewage lifting operation according to the illustration according to FIG. 4 occurs and the separating sieve 6 is flushed free of the solids adhering thereto, a reduction in the angle of inclination ⁇ is observed. Indeed, the oblique angle ⁇ is reduced by approximately 5 by the described sewage lifting operation ° to 10 °. In the embodiment and the inlet of the wastewater according to Figures 1 and 3, the oblique angle ⁇ may be located in the range of about 45 °.
- the sewage lifting operation according to FIG. 4 corresponds in the example case to an oblique angle ⁇ of approximately 40 °. It goes without saying that these details are given by way of example only and are not restrictive in any way.
- the hinged edge-side edge region 6a As a result of the circular disk segment-like design of the separating screen 6, the hinged edge-side edge region 6a, as shown in FIG. 2, describes a circular arc whose radius is adapted to the inner radius of the hollow cylindrical collecting container 3.
- the separation screen 6 is at the inlet of the wastewater according to the illustrations in FIGS. 1 and 3 at the correspondingly curved sealing region 16 on the inner wall of the bulk material collecting container 3. Consequently, at the inlet of the waste water and the system of the separating sieve 6 at the sealing region in question 1 6, the separation sieve 6 ultimately only pass solids that "fit" from their average or cross-section through the longitudinal slots 13.
- the pump 5 ensures that now takes place a reversal of direction of the sewage stream. While in the context of Fig. 1, the wastewater has flowed through the inlet 1 through the separating screen 6, the non-barrier area 3b and the connecting line 4 and finally reaches the pump 5, now takes place a reversal of the flow path, as shown in FIG 4 indicated arrows for the flow of sewage is clear.
- the pump 5 provides for a lifting operation of the waste water and generates the flow shown in FIG. 4
- the separating screen 6 is swung as it were high while reducing the oblique angle ⁇ and removes as a result thereof the hinge-side edge region 6a of the sealing region 16. An This point, therefore, a flow passage 17 is observed.
- any fibers located in the longitudinal slots 13 are stripped off the separating screen 6, because the longitudinal slots 13 are each open to the relevant hinged edge region 6a of the separating screen 6 and consequently in the direction indicated by an arrow during flushing.
- any further solids retained by the separation screen 6 are rinsed off and removed from the separation screen 6.
- any adhering to the webs 7 solids are also stripped and promoted via a pressure line 1 8 to a remote wastewater treatment plant.
- the shut-off flap 2 located in the supply line 1 is closed as shown in FIG. 1, so that the raised waste water is all promoted together with the solids in the pressure line 18.
- the butterfly valve 2 and the butterfly valve 8 can also be combined.
- the butterfly valve 8 of the combined shut-off / screening device 7, 8 at the same time provides a closure of the supply line 1. This applies in any case for the pumping operation or wastewater lifting operation while the wastewater inlet the supply line 1 is opened and the butterfly valve 8 is closed and the opening 9 hidden.
- flow baffle 1 1 may assist the purge described to the effect that in each sewage lifting or pumping operation both the separating screen 6 and the butterfly valve 8 of the combined shut-off / screening device 7, 8 opened become. This is exemplified in Fig. 4 expressed.
- the flange 10, the separating sieve 6, the combined shut-off / sieve device 7, 8 and the bypass 11 and all or part of the housing of the bulky substance collecting container 3 have a structural unit 10, 6, 7, 8, 1 1 form.
- This assembly 10, 6, 7, 8, 1 1 can be used in the bulky / collecting tank 3 respectively with an additional and not shown end flange to the bulk material collection container 3 are completed.
