Definitions

  • the invention relates to a waste water collection container for a sewage lifting plant with a sloping to a deep area tank bottom, wherein above the deep area is a space area from which the wastewater is sucked out under normal use of the sump.
  • Collecting tanks are used in pumping systems that collect wastewater, such as sewage contaminated black water or gray water, some rainwater that accumulates below the backflow level and therefore can not be introduced via a natural gradient in the public sewer.
  • the effluents are therefore introduced via a sewer collector into the sump, from which a pump unit, the waste water as needed, usually depending on the level, via a pressure line to a geodetic height above the sewer raises, so that it can flow into them.
  • the pump unit thus pumps the waste water out of the sump.
  • Wastewater lifting plants of this type are found both in the domestic area, where only the waste water of a single Wasserverbrausstelle such as a toilet, shower, a sink and / or a washing machine, a whole apartment, such as a basement apartment, or a whole house are collected in commercial buildings and Building complexes such as hotels, hospitals, department stores, etc., as well as in the municipal area.
  • the lifting systems or their collection containers are dimensioned differently sized. This is the gross volume a collection container for small domestic installations typically between 10 and 150 liters, for large systems typically between 150 and several 1000 liters.
  • Wastewater lifting plants with collecting container are, for example, from the German patent application DE 102005027091 A1 and the European patent application EP 2 489 801 A1 known.
  • Other sewage lifting units are available on the market under the name WILO-DrainLift and in the publications DE 20 2011 004561 U1 .
  • German patent application DE 590 848 C describes a fluid delivery device through which the sanitary facilities in hospitals, clinics, and other designated for medical practice rooms can be connected to the drains leading to the sewer, even if they are far from the latter.
  • a collecting container is described, which has a first recess into which the suction nozzle of a pump projects to remove the liquid as completely as possible from the container.
  • a second bottom well is provided here into which extends a well having a float movable up and down therein which cooperates with a mercury toggle switch in an airtight sealed chamber on the lid of the container to activate the pump motor.
  • the solid particles are mostly sticky, especially partially fibrous and that fats and oils are present in the wastewater which adhere quickly to the inner wall of the container, especially on the ground. The deposition of solids in the sump therefore requires short maintenance intervals for cleaning.
  • a collecting container in the container bottom two elongated depressions are formed, which extend sloping to each a private deep area, between the wells is a hill and above the low areas each a space area for proper aspiration of the wastewater.
  • the container bottom thus has a surface deviating from a plane which forms the bottom of the container. This reason has a deep relief through the depressions.
  • the collecting container according to the invention is intended for a sewage lifting plant with two pump units, the wastewater from each suck a separate room area, ie for lifting systems with two extraction areas. Such lifting systems are for cases in which the inflow to the lifting system during normal operation must not be interrupted.
  • the second pump unit should be equipped with the same capacity to replace the first pump unit, at least temporarily, completely.
  • the usual operation of the two pump units is then alternately, ie that either the one pump unit or the other pump unit in Go operation.
  • the elongated depressions are thus each directed to a separate suction area, so that the main flow in the container during a pumping down along the recess. This achieves an automatic cleaning effect.
  • the container bottom geometry according to the invention prevents a flow-calmed or even flow-dead zone from forming on the container bottom between the two spatial regions / suction regions and in the intermediate region along the two depressions.
  • the falling due to their own weight to the ground solid particles are largely directed in the direction of the slope and thereby guided quasi. Due to the fact that the depressions each open into a separate deep area instead of a common low level at the foot of a gradient, the solid particles sedimented within one of the depressions can be better absorbed by the suction of the waste water from the direction of the corresponding spatial areas and be entrained with the flow since they accumulate in the wastewater at the bottom of the respective room area.
  • the recesses may be adjacent to each other, so that the hill is a substantially elongated hill.
  • the recesses may extend substantially parallel to one another, in particular have the gradient in the same direction.
  • the recesses may also diverge and thus describe a V-shape.
  • the slopes can run in different directions, in particular in opposite directions.
  • the depressions can likewise be approximately parallel, diametrically opposite or offset diametrically opposite, so that they describe an I, Z or S shape.
  • the gradient of the recesses may be less than 16 ° in the longitudinal direction of the deep regions, for example. This small gradient is sufficient to absorb sedimented sediment with the flow or entrain. On the other hand, this achieves the result that, despite the increase in the floor area on one side, the collecting container does not have to be structurally much higher and at the same time a large container volume remains.
  • the slope does not necessarily have to be constant along the baseline of the recesses. It is rather advantageous if the depressions have sections of different pitch in the longitudinal direction. This is especially important in view of the fact that solid waste containing wastewater flows from the suction into the sump. This is e.g. then the case when the pumping unit is turned off and sewage flows back from the drainage piping, so that the solid particles are flooded the well "high".
  • an area for example a central area, which has a higher pitch than the one or the remaining areas can be formed in the gradient of the depressions. Such a region causes a particle separation when the corresponding depression is overflowed from the direction of the space region.
  • the slope of a region in particular of a middle region, may be two or three times the slope of an upper or lower region.
  • the invention relief of the soil enhances the flow within the container by the respective wells acts as a streambed while sucking the wastewater from the located at its end space area. This promotes the absorption of settled particles from the soil into the suction flow and optimizes the self-cleaning effect when lifting the wastewater.
  • the elevation between the two depressions reduces deposits in this area. They slip by themselves to the baseline of one of the recesses and ideally further to their depth range or are entrained due to the exposed position both in the operation of one and the other pump unit.
  • the pump units may be arranged in or on the collecting container or externally to this, so that either the suction mouth of the pump units is above the spatial areas or the inlet opening of a suction pipe above the room areas, the latter is then connected to the suction of an externally arranged pump unit.
  • Each of the depressions then extends in a direction from which one of the pump units sucks the wastewater in the collecting container.
  • the suction port of the pump set or the inlet opening of the suction pipe are ideally above the respective depth range.
  • the depressions are ideally modeled on a natural, shallow seabed, so that they are not only longitudinally but also transversely thereto, i. to the sides have a slope in the direction of a longitudinally extending baseline.
  • the baseline is that line which, viewed in cross-section, connects the deepest points of the depression.
  • To the sides of the baseline rises the bottom of the depression and consequently the bottom surface.
  • This illustrates that the container bottom not only has a slope in at least one direction, namely the extension direction of the baseline, but is overall uneven.
  • the depressions accordingly have a higher initial region and a lower end region in this respect. With respect to the beginning, the depressions become ever deeper, in particular steadily, in order to avoid flow shadows.
  • the two depth ranges are at the same level.
  • they can each correspond to the lowest point of the container bottom.
  • the container bottom is designed to be low-level, so that outside the deep regions at the end of the depressions there is no further deep region, in particular no such deep region is present in a possible base. This ensures that deposits can not form at any point other than at the end of the recesses or at the bottom of the room areas.
  • the shape of the depressions ideally corresponds at least below a certain level in the representation as a closed contour of depth essentially to a slipper, a kidney or a seedling.
  • a corresponding suction flow is performed optimally.
  • a first depth line at a first level may describe the outer shape of a seedling, ie corresponding to a germinating seed, a second depth line on a second Level higher than the first level describing the outer shape of a kidney or kidney bean, and a third depth line on a third level higher than the second level describing the outer shape of a slipper.
  • the recesses in the container bottom become wider and thus act like a funnel. This means that the depressions become progressively narrower in the extension direction downwards, at least above a certain level, between the second and third levels. This has the effect that particles that precipitate in the raised area of the collecting container, are better sucked.
  • the wells are "back-to-back".
  • the base line of the depressions in each case runs in an arc shape, in particular runs from the container collecting space to the suction region. Since the suction due to the hydraulic reaction of the impeller of a pump unit is a circulating flow, this geometry also has a favorable effect on the flow and enhances the suction at the opposite end of the corresponding recess, ie. at the back of the container.
  • the depressions merge into one another above a certain level.
  • the elevation may have a local minimum, in particular in the region of the lower third of its longitudinal extent. This means that the elevation increases from a minimum height defining the level to the opposite end regions of the depressions. However, as the pits fall off towards the bottom, this means that the difference in height between the baseline of the pits to one of the ridges connecting the highest points of the hill in cross section becomes larger and larger becomes. This also increases the slope of the hill to the bottom of the wells, the closer the elevation is located at the spatial areas, so that in the area between the two deep areas a greater gradient in the direction of the deep areas is present, as the hill in the rest of the area to the baseline Has depressions. This is due to the fact that the bottom area in the container between the two areas of space from which is sucked, forms a more flow-smooth area, as he is otherwise on the rise. The increased slope also reduces the risk of deposits.
  • the depressions above the minimum height combine to form an overall depression, the shape of which in the representation corresponds essentially to a butterfly as a closed contour of depth.
  • the highest areas of the ground geometry lie at both ends of the length of the elevation between the depressions.
  • the risk of deposits is given to a particular extent both in the case of a suction flow from the direction of the one spatial region and also in the direction from the other spatial region. This danger is minimized by the elevated areas at the end of the hill.
  • the butterfly shape means that the slope widens towards the ends of its longitudinal extent, so that on this very wide surface the possibility of deposits is reduced. In particular, depositing particles, insofar as they do not slip through the gradient of the recesses to one of the deep regions, are detected and transported away by one or the other suction flow.
  • the container bottom on both sides of the hill drops from each point in the direction of the respective depression. This means that beyond the elevation between each point of the ground surface and the low region lying on this side of the elevation is a gradient, so that the solid particles already slip due to their own weight to the lowest point and can be sucked from there. Furthermore, it is completely avoided that the container bottom dead zones, ie area has no flow in which sediment would be deposited. Consequently, in this embodiment there is no planar area on the container bottom. Inner edges are ideally formed by inner curves that guide the flow and thus do not form a deposit for sediment.
  • the collecting container comprises a tower-like main collecting space, the bottom side has at least one extension, wherein the space regions each form a rear portion of this at least one extension.
  • the extension extends in the radial direction beyond a container wall of the main collecting space. Due to the extension, the floor area is enlarged, so that the recess is longer.
  • the extension serves primarily as a base for the arrangement and in particular for the assembly of other components of sewage lifting plant such as solids separation tanks and / or pump units, so that no further space is necessary laterally next to the collection container for these components. Rather, these components may be located on the at least one extension, i.
  • the lifting system can be done largely factory and installation at the site is quick and easy.
  • the assembly of the pump units on the extension has the advantage that they are dry and do not have to be designed as submersible pumps, whereby the structural design can be much simpler.
  • the pump units also do not necessarily have to be self-priming, because the impeller is always below the filling level when the collecting container is filled accordingly.
  • the collection container may also have two extensions that may extend in different directions. All features mentioned above and below then apply mutatis mutandis to each of these extensions with the proviso that each of these two extensions is the same function with one half of the extension is in the embodiment of the collection container with only one extension. For example, the two areas of space each form a rear area in one of the two extensions.
  • the container cover of the at least one extension has two openings, each of an annular mounting surface for mounting a Pump unit or a suction tube are surrounded.
  • each of the two extensions has such an opening with a mounting surface.
  • the mounting surface is a mounting flange.
  • the assembly of the pump units or suction pipes can be done directly on the mounting surfaces. But it is also possible to mount an intermediate ring (Adapterflansch) on the mounting surface on which then the pump unit or suction pipe is mounted. This allows a high mounting flexibility, especially when pump unit or suction pipe with respect to the container to be arranged in a certain way. Furthermore, no adaptation to the mounting surface and pump unit or suction pipe must be made if one of the components to be assembled is structurally changed.
  • each well i. the corresponding deep area is suitably located directly below one of the openings, so that the suction mouth of a pump unit mounted on the mounting surface or the mouth area of a suction pipe mounted on the mounting surface is directly above a low area or at least directed thereto and thus can suck the waste water directly from the tank floor ,
  • the mounting surfaces can basically lie in a horizontal plane. However, it is advantageous if the mounting surfaces lie in a plane which is tilted with respect to a horizontal plane, in particular tilted away in the direction away from the main collecting space. This causes a pump set mounted on the mounting surface not to be perpendicular, but slightly tilted in the direction away from the main collecting space.
  • the mounting surfaces may be tilted by less than 10 °, in particular less than 5 °, preferably between 2 and 4 ° with respect to the horizontal plane.
  • the pump units are positioned so that the pressure-side outlet of the pump unit is higher than the rest of the pump chamber, on the one hand automatic ventilation of the pump unit and its area in front of the suction port and the pressure line behind the pump chamber is achieved, on the other hand, there is a gradient in the pressure line in the direction of the pump chamber, which favors the inflow of waste water through the pressure side, if the Lifting plant is set up to introduce the wastewater via the pressure lines of the pump units in the collecting tank space.
  • the underside of the container ceiling of the extension has at least partially a slope in the direction of the main collecting space towards the top. This may be an angle of inclination preferably between 3 ° and 8 °. It favors that in the expansion located oil or fat floating in the main collecting space and thus does not adhere to the container ceiling of the extension. Oils and fats are increasingly contained in wastewater and float due to their lower density, as is known, at the water surface. You get for example by filling the sump on the pump units or by running back of wastewater after switching off the active pump unit in the extension. Due to the hydrostatic pressure exerted by the accumulated waste water in the expansion on the oils and fats, these are pressed against the underside of the container ceiling of the extension and thereby tend to attach particularly well.
  • the upper side of the container ceiling of the extension at least partially has a slope in the direction away from the main collecting space. This prevents water from accumulating on the extension. For this could happen, for example, when rainwater enters the shaft in which the collecting container and the wastewater lifting plant is set up. Such shafts usually have a relation to the footprint of the lifting system deeper collecting space in which a drainage pump is arranged to remove rainwater from the shaft.
  • the fact that water drains from the top of the tank due to the slope also reduces the risk of slipping of a person who has to make the expansion for maintenance purposes.
  • the container top of the Extension have a non-slip, especially rough surface, which ensures a firm grip under the feet when climbing the extension.
  • the outside of the container ceiling of the extension and the mounting surfaces are substantially parallel, so that a slope of the ceiling of the extension automatically causes the mounting surface has a slope. This ensures that the wall thickness of the container ceiling in the extension direction of the slope remains the same. This saves material and consequently weight at the collecting container.
  • the extension has bulges in the radial direction which are formed by sections of the container wall of the extension which extend around the space regions. The space areas from which is sucked, thus at least partially protected in these bulges. This causes a directed suction flow to develop in the direction of the main collecting space.
  • the bulges are part-circular cylindrical, so that the sections of the container wall extend arcuately around the space regions, in particular around the mounting surface. There are thus no corners and kinks in the container wall, whereby no flow-calmed corners bottom side of the container wall exist in which deposits could form. Further, the part-circular cylindrical shape of the bulges causes the circular suction flow, so that the hydraulic efficiency is improved. Because in the case of the wastewater from the Saugraum Society aspirating pump set this generates in the Saugraum Berlin due to the rotating impeller a vortex.
  • the arcuate portion of the container wall around the mounting surface, ie around the suction space, thus follows this circular orbit flow, so that the container wall forms only a minimal hydraulic resistance, at least with respect to a container shape, in which two container walls lying at right angles to each other around the suction space run.
  • the bulges have the advantage that at least a part of the room areas is protected from the other room area, so that in one of the room areas incoming or backflowing wastewater does not get directly into the other room area.
  • the collection container is constructed symmetrically with respect to a vertical plane through the elevation, so that the depressions are symmetrical opposite each other and the depth ranges are at the same depth level.
  • the two recesses may, for example, be V-shaped relative to one another. This means that the recesses extend in different directions, but from the same side away from the main collecting space and an angle between the directions of extension. As a result, a particularly compact design for the wastewater lifting plant is achieved. However, other geometries are possible.
  • the collecting container may have two extensions on the bottom side, wherein at the end of each of the extensions there is one of the spatial regions to which one of the two elongated depressions with depth region extends at the end.
  • the second extension can lie on the side of the collecting container which faces away from the first extension, which then preferably extends in the direction opposite to the first extension.
  • each of the two extensions each having an opening with a surrounding mounting surface for mounting a pump unit or suction pipe. In this way, a substantially Z- or S-shaped course of the recesses can be realized.
  • the collecting container can be made of Kunststoffsoff, for example made of polyethylene (PE). He has a comparatively low weight. It may ideally be made by rotational sintering so that it does not have weld lines that could affect stability. Rotational sintering is known per se to a person skilled in the art.
  • the container bottom has ribs formed on the underside for supporting the collecting container on a base.
  • These have the advantage over conventional support feet to be able to absorb a large weight.
  • the bottom surface of the container may further be formed substantially flat become. The latter would be reasonably possible with support feet only if they were not hollow but solid, for example made of plastic. However, this is not possible by rotational sintering. Further, because of shrinkage effects, which are the greater the thicker the plastic, sinking in the area of the support feet would result, which in turn would absorb deposits.
  • the entire container bottom can be stably supported on the ground. without causing a "sagging" of the container bottom. This danger would exist at widely spaced support feet. Due to the stability obtained by the ribs, the container bottom can also be thinner than comparable storage containers with support feet, whereby material and weight is saved.
  • the ribs preferably extend in the direction of the extension, ideally between lifting eyes provided on the container. This has the advantage that there is a particularly high bending stiffness in the direction from the main collecting space to the extension. This is necessary in order to avoid a breakage of the container, in particular of the container bottom, when the collecting container together with assembled pump units and possibly filled or partially filled at the lifting lugs is lifted or lowered from a shaft. If the ribs were transverse to the extension direction of the extension, there was a lack of longitudinal stabilization. There would then be a risk that the sump would break due to the pump weight at the end of the expansion and the weight of the main sump in the area between the main sump and pump units.
  • the invention further relates to a sewage lifting plant with a collecting container of the type described above.
  • a sewage lifting plant which has two pump units for pumping the waste water from the collecting container, wherein the pump units each have a pump housing having an inlet in the axial direction in an impeller receiving pump chamber and an outlet in the radial direction of the pump chamber, and Sump has a tower-like main collection space with a bottom extension in which the space areas are, the extension has two openings, above which the extension each carries one of the pump units and below which each one of the space areas, is sucked from the wastewater during operation of the pump unit ,
  • the wastewater lifting plant according to the invention may also be designed symmetrically.
  • the wastewater lifting plant may preferably comprise two solids separation tanks connected to a common inlet, which in each case communicate with the outlet, i. connected to the pressure side of one of the pump units, so that incoming via the inlet wastewater flows through at least one of the solids separation vessel and then via the associated with this solids separation tank pump unit in its disconnected state into the collection.
  • the wastewater flows through both solids separation tanks and then into the sump tank space via both pump units, provided that none of the pump units are in operation.
  • this construction has the advantage that, during operation of the respective pump unit, the solids separation tank connected to it is cleaned.
  • the wastewater is pumped through the solids separation tank in a pressure line, from where it then flows into the sewer system.
  • a check valve for example in the form of a floating ball valve, which is arranged at the inlet side entrance of the solids separation container, closes during the lifting operation of the pump unit, the solids separation vessel, so that the waste water is not forced into the inlet. Meanwhile, incoming wastewater flows into the sump via the other solids separator and the second pump unit.
  • the two pump units or suction pipes do not necessarily have to be in operation at the same time in order to pump about a larger amount of water per minute from the sump. Rather, the Pump units or suction pipes preferably operated alternately. For a redundancy is realized on the one hand. Thus, one pump unit can maintain the function of the lifting system if the other pump unit should be defective. The alternate pumping operation also allows wastewater to be introduced into the sump via one pump unit or suction tube while the other pump unit or siphon raises waste water from the container.
  • the longitudinal axis of the pump units is tilted relative to the vertical, wherein the outlets are located in the higher part of the pump housing. This can ideally be accomplished by mounting the pumps with their pump housing flange surrounding the inlet onto the inclined mounting surfaces of the sump extension.
  • the outlets of the pump housings each form the highest point of the respective pump housing.
  • the pump units are mounted with their pump housings with respect to the sump on the extension, that the radial direction in which the outlet is located from the pump chamber, is parallel to the slope of the mounting surfaces.

  • the depressions 19 each extend to a separate depression 9. They resemble a natural, shallow lake bottom, so that they have not only in the longitudinal direction but also transversely thereto, ie to the sides of a slope in the direction of a longitudinally extending base line 21.
  • the baseline 21 is the line that connects the lowest points of all cross sections through the recess 19 with each other.
  • the container bottom 39 consequently has a gradient not only in at least one direction, in particular in the extension direction of the baseline 21, but is overall uneven.
  • the recesses 19 accordingly have a higher initial region 24 and a lower end region 23, see FIG Figures 2 and 5 , With respect to the initial region 24, the recesses 19 become deeper and deeper.
  • the container 4 has no low points or deep areas, in particular no hollow support feet, in which solids could be deposited.
  • the shape of the recesses 19 corresponds at least below a certain level in the representation as a closed contour of depth substantially the silhouette of a slipper, a kidney or a seedling. As a result, a suction flow is optimally guided through one of the depressions 19.

  • a third depth line T3 at a third level which is higher than the second level, describes approximately the outer shape of a slipper.
  • the depressions 19 in the container bottom 39 thus become wider and thus act like a funnel.
  • This bottom geometry also takes into account the laterally extended by the side wings 26 bottom area. Due to the wider initial region 24, the recesses 19 virtually aspire into the side wings of the extension 7. Conversely, this means that the depressions 19 become progressively narrower in the direction of extent downward. This has the effect that particles that precipitate in the raised area of the collecting container, are better sucked.
  • a hill 38 Between the recesses 19 is a hill 38, which clearly in the FIGS. 4a to 4f can be seen.
  • the symmetry of the container is with respect to a vertical plane through the hill 38, so that the recesses 19 are symmetrical opposite and the depth regions 9 are at the same depth level.
  • the recesses 19 are adjacent to each other in the length, so that the hill 38 is a substantially elongated hill 38.
  • the inclines of the depressions 19 run approximately parallel along the baseline 21, although the baselines 21 are slightly curved in their own right, because of the symmetry of the ground 39 with respect to the rise 38.
  • the two depressions 19 merge into one another above a certain level so that they combine to form an overall depression, the shape of which in the illustration corresponds essentially to a butterfly as a closed depth line T4. This has the effect that a suction flow along one of the depressions 19 above the said level also becomes noticeable at the bottom of the other depression 19 and entrains sedimented solid particles there.
  • the hill 38 has a local minimum approximately in the region of the lower third of its longitudinal extent. This is particularly in the cross-sectional view in FIG. 6 recognizable. This means that the rise 38 rises from a minimum height defining the level to the opposite end regions 23, 24 of the depressions. However, while the depressions 19 drop toward the deep regions 9, this means that the height difference between the baseline 21 and a crest line connecting all crests of the rise 38 becomes ever greater.
  • the gradient from the rise 38 to the bottom of the depressions 9 also increases, the closer the rise 38 is located to the depression areas 9, so that in the area between the two depression areas 9 there is a greater gradient from the rise 38 in the direction of the depression areas 9, as the hill 38 has in its remaining area to the baseline 21 of the recesses 19. This is due to the fact that the bottom area in the container 4 between the two deep areas 9, from which is sucked off, forms a more flow-smooth area than otherwise present on the hill 38. The increased slope also reduces the risk of deposits.
  • the aforementioned level, above which the two Recesses 38 merge into each other corresponds to the said minimum height of the hill.
  • the container bottom 39 drops on both sides of the hill 38 from each point in the direction of the respective depression 9. This means that beyond the rise 38 between each point of the bottom surface and the low region lying on this side of the hill 38 is a gradient, so that the solid particles already slip due to their own weight to the lowest point and can be sucked from there. Furthermore, it is completely avoided that the container bottom dead zones, i. Area of lack of flow in which sediment would settle. Consequently, in this embodiment there is no planar area at the container bottom 39 at any point. Inner edges are formed by inner curves which guide the flow and thus do not form a deposit possibility for sediment.
  • the deep regions 9 is in each case a spatial region 14, from which the wastewater is sucked out of the container 4 during operation of the lifting plant 1.
  • the two space regions 14 thus form suction areas.

  • the transition of the container bottom 16 to the side walls of the extension 7 lying laterally of the recesses 19 and a line connecting all the vertices 29 of the ledge 38 can each be considered as a shoreline.
  • the distance of the baseline 21 with respect to these shorelines becomes larger and larger as the depressions 19 advance toward the respective depression region 9, so that the container bottom 16 is highest below the shore lines, ie at the edge sides and in the middle, ie the underside of the container bottom 16 the farthest spaced from the footprint of the container 4, as in FIG. 4a becomes clear.
  • the container bottom 16 rests on its underside in the region of the deep regions 9 on the installation surface of the collecting container 4.
  • the extension 7 furthermore has two part-circular cylindrical bulges 40 in the radial direction, which are each formed by a section 15 of the container wall 28 of the extension 7 which extends in an arcuate manner around a space region 14. Between the sections 15 is a connecting portion 27 which is also arcuate, but is directed with its back to the container interior. The space regions 14, from which is sucked, are thus at least partially protected in the bulges 40 a. This causes a directed suction flow can develop in the direction of the main collecting space 11.
  • the part-circular cylindrical shape of the protrusions 40 guides the circular suction flow, so that the hydraulic efficiency is improved. Because in the case of a wastewater from the Saugraum Society 14 suction pump unit 5 this generates in the suction chamber 14 due to the rotating impeller a vortex.
  • the arcuate portion 15 of the container wall 28 around the mounting surface 10, ie around the suction space area 14, thus follows this circular orbit flow, so that the container wall 28 forms only a minimal hydraulic resistance, at least to a container shape in which two are perpendicular to one another lying container walls extend around the suction chamber 14.
  • the bulges have the advantage that at least a part of the space regions 14 is protected from the respective other space region 14, so that in one of the spatial areas incoming or backflowing wastewater does not reach directly into the other space region 14.
  • the collecting container 4 is intended for a sewage lifting plant 1 with two pump units 5, which suck wastewater from each one of the space regions 14.
  • the two openings 8 are arranged above the space regions 14, see FIG. 4a ,
  • a pump unit 5 or a suction pipe can be mounted here to the collecting container 4.
  • the elongate depressions are thus each directed to a separate suction area, so that the main flow in the container 4 during a pumping process along the recess 14 extends. As a result, an automatic cleaning effect along the recesses 19 is achieved.
  • the container bottom geometry according to the invention prevents a flow-calmed or even flow-dead zone from forming on the container bottom 39 between the two spatial regions 14 / suction regions and in the intermediate region along the two depressions 19.
  • the gradient of the recesses 19 may be less than 16 ° in the longitudinal direction of the deep regions 9, for example. This small gradient is sufficient to absorb sedimented sediment with the flow or entrain. On the other hand, this achieves the result that, despite the increase in the floor area on one side, the collecting container does not have to be structurally much higher and at the same time a large container volume remains.
  • the slope of the container bottom 39 in the direction of the main collecting space 11 is particularly important in view of the fact that wastewater containing solid particles from the suction can flow into the collection or intended, even flows.
  • the former is the case when the conveying pump unit 5 is turned off and the sewer column from the outgoing pipes 6, 13 flows back.
  • the latter is the case when the filling of the collecting tank via the pump units takes place. In both cases, the solid particles flush the wells "high". Due to the slope is prevented or at least minimized that heavy particles are washed up the slope.
  • the relief according to the invention of the bottom substrate 39 improves the flow within the container 4 by the respective recess 19 acts as a streambed while sucking the wastewater from the located at its end space portion 14. This promotes the absorption of settled particles from the bottom 39 in the suction flow and optimizes the self-cleaning effect when lifting the wastewater.
  • the hill 38 between the two recesses 19 is mainly in the Figures 4c and 4d clearly visible. It has the shape of a flat hilltop and is in the Cross-section considered in height as shallow as the wells in the depth, so that the container bottom 16 in cross section has approximately an elongated sinusoidal shape.
  • the vertex 29 of the hill 38 is located in the vertical sectional plane along section BB in FIG. 2 , By the hill 38 permanent deposits between the wells 19 are avoided. Particles either slip by themselves to the baseline 21 of one of the depressions 19 and ideally further to their depth region 9 or are entrained due to the exposed position both during operation of the one and the other pump unit 5.

  • the thickness of the container bottom is approx. 15mm.
  • the rib height decreases to the distal end of the extension 7, ie with increasing distance from the main collecting space 11. There, where the lowest point 9 of the recess 19, the rib 22 has the height zero is therefore no longer present.
  • the container bottom 16 touches the footprint on which the sump stands, as shown in FIGS. 4a, 4b is apparent.
