Definitions
- the present invention relates to what is claimed in the preamble and thus deals with the overflow of water.
- Water is collected in sewer systems, and then its Processing to be fed.
- Mixed water systems Sewage from households together with rainwater collected and sent to wastewater treatment plants. But this is only possible, as long as the capacities of the facilities provided suffice. Exceedances now occur, especially in the event of rain the clarification capacity. Since it is for cost reasons it is not possible to use wastewater treatment plants for rain events To design strength, rainwater overflow basins are provided in which the mixed water backed up during heavy rainfall can be. If the capacity is no longer sufficient, so the mixed water is only mechanically cleaned in the given waters serving as receiving water.
- the mixed water in it exceeds provided overflows an overflow threshold and is from forwarded to the receiving water there.
- the endangerment of the receiving water due to pollution of the overflowing water as a rule, at most low, because with the very heavy rainfall, that typically trigger such events, little Foreign substances are carried along and the concentration of contaminants is correspondingly low.
- the object of the present invention is to create something new to provide for commercial use.
- a first essential aspect of the invention is thus in the Realization to see that a rake is realized in a lifter can be removed without the risk of the wastewater liquid column breaks in the siphon or the fluid flow is significantly affected by the jack.
- the order of rakes or sieves, which are also understood here as rakes and overflow threshold in the siphon initially has to Consequence that the overall arrangement is formed much smaller can be.
- the arrangement also has another advantage in that that the rake or sieve is better than comparable ones conventional computer systems against pollution, Constipation and addition is protected.
- conventional Plants water flows permanently in one direction as long as it is high. If the water level falls conventional systems, the flow movement also ends. Perhaps Coarse material washed against the rake remains then essentially there.
- the system tears the liquid column when the water level drops in the lifter. Then the water flows in the upper one Lifter area not only to the downstream lifter exit, but at least partly to the upstream elevator entrance. With this reflux movement, part of the counter taken the coarse washed-out coarse material and such be removed from the rake again. This extends the Cleaning intervals and / or the cleaning time and thus overall, the operating costs decrease.
- the rake is curved Lifter bent. This makes it longer than a position immediately perpendicular to the flow direction; this leads to, that washed up substances over a larger area can distribute and therefore not clogged the rake so quickly. Substances with a slower flow are also used in the rake deposited, so less firmly against or between the Rakes or sieve meshes pressed. This makes it easier Flush out when the jack is torn off and also the cleaning.
- the rake bars are preferably attached or fixed on one side includes. This is advantageous because it allows the Rake is hinged upwards and / or that the rake relatively movable, in particular resilient rake bars having. The foldability improves cleaning, because after folding up very easily the typical from below coarse material washed against the rake can be removed. Even if the rakes are springy, this makes it easier the cleaning continues.
- the rake can also include round bars and / or be built exclusively with such. Another preferred embodiment has a crescent shape Sheets on the z. B. 4 mm side by side could be.
- the threshold In a particularly preferred variant is through the threshold the lower lifting arch is realized. This has the advantage that for the jack essentially only an upper jack hood is required, which simplifies the conception.
- the threshold can be formed with a solid threshold plate be so that a permanent proper flow pattern is guaranteed.
- the threshold can be set to one Partition can be arranged.
- the lifter is a compact element provided with side walls. Manufacturing with such Side walls significantly facilitate the installation of these jacks on site.
- Coarse material collection area Downstream of the threshold and before the rake, i.e. related on the rake on the inflow side, one is preferred Coarse material collection area attached.
- the rake will quasi around the threshold and up to the coarse material collection area pulled into it. This has the advantage that at least considerable parts of the coarse material are guided along the screen and then in a no longer flowed area collect for later removal.
- Particularly advantageous is a one-sided linkage to that of Coarse material collection area facing away and a compliance the rakes by resilient formation of the same, then the rake from above into the coarse material collection area can be led into it.
- this articulation will typically be flooded when the lifter responds.
- the equipment with wastewater resistant materials is therefore particularly desired. So stainless steel or the like can be used become.
- the articulation area is typically designed in this way be that it is self-draining.
- the coarse material collection area is preferably an emptying opening assigned, in particular an emptying opening with a float-controlled emptying flap in particular.
- an emptying opening assigned, in particular an emptying opening with a float-controlled emptying flap in particular.
- the emptying opening becomes typical of the continuing sewer or via a pump arrangement or throttle device Reflux fed to a sewage treatment plant so that the coarse matter can be properly treated there.
- the drain opening into a further channel leads it is preferably arranged or formed, for example by providing a float control or the like.
- the flap control is preferred in this respect than than the entire water overflow arrangement current-free and / or without electronic or microelectronic Control can be operated. This increases operational security essential and at the same time lowers the maintenance and Maintenance costs.
- the upper lifter arch is preferably provided with a removable, in particular hinged lid formed. This allows one very quick access to the water overflow arrangement.
- the upper lifting arch can implement an emergency hold-up, that responds when there is extremely heavy rainfall the intended lifting power is no longer sufficient to to drain the incoming water.
- the cover acts preferentially in the lift inflow area as a diving wall that does not allow floating Substances such as polystyrene blocks or oil films are forwarded.
- the lifter is one Demolition opening assigned to the lifter after the water has dropped idle very quickly below a predetermined threshold leaves. This quick tear-off is desirable to the aforementioned Favor self-cleaning.
- the lifter continues above the rake preferably include an amount of water that is sufficient to allow the rake to tear when the lifting action breaks off do the washing up.
- the water overflow arrangement is also particularly in comparatively high receiving water, i.e. water bodies, in which is ultimately the amount of water flowing over the threshold should arrive at the outflow area in particular have float-controlled backflow prevention flap.
- the arrangement can preferably be in or with a rain overflow structure used or constructed with this. It is mentioned here that the possibility of such a structure to be able to provide at any given point for reasons of space, fundamentally from the flow technology Improvements and the smaller footprint may depend on the arrangement disclosed. It should also be mentioned that it is possible to use several of the water overflow arrangements to be used side by side. Side by side means not necessarily linear and directly next to each other; so can create paths on a partition between the water overflow arrangements be provided or it will be round or differently shaped overflow structures provided along their Randes repeated with overflow arrangements of the invention are provided.
- 1 comprises a water overflow arrangement, generally designated 1 1 an overflow threshold 2 and a rake 3, which are arranged in a lifter 4.
- the water overflow arrangement 1 of the invention is present on the threshold of a rain overflow structure 5 like a canal arranged. It is dimensioned for that in the rain overflow structure water masses that can no longer be stored properly to drain off. This is the water overflow arrangement 1 from several identical module structures one given, still easy to handle during creation Size composed.
- a wall 5a of the rain overflow structure 5 also forms a partition that crosses the overflow threshold 2 flowing masses of water from the retained Masses of water separate.
- the overflow threshold 2 is fixed attached to the partition 5a and by a sufficient stable curved overflow plate 2a made of stainless steel.
- the overflow plate protrudes over a coarse material collection area 6 above, the downstream of the partition at one level is arranged in the lifter, which is clearly below the overflow threshold 2, but at or above the lift exit 4a lies.
- the coarse material collection area 6 is here as preferred possible, equipped with a perforated plate in the upper area.
- the size of the coarse material collection area is dimensioned that occur during typical overflow events Coarse quantities can be safely taken up in it; the Screen perforation is dimensioned so that the coarse materials at least are retained without substantial blockage of the holes.
- An emptying channel leads from the coarse material collection area 6 7 to an emptying opening 8 in the partition 5a, which by a float-controlled flap 8a is kept closed, as long as the water in the rain overflow structure 5 is sufficiently high stands.
- the rake 3 is made up of a large number of parallel stainless steel rods 3a formed, which is articulated on one side at a joint 9 are on a perpendicular away from the top edge of the partition Arm 10 led to the rain overflow structure and upstream the overflow threshold is arranged.
- the bars are there only fixed on one side and free on the downstream side movable. Their distance from each other is chosen so that the coarse substances to be retained do not pass between the rods can penetrate. This is with typical pollution for a distance of around 4mm.
- This one out Spring bars made of spring steel are around the overflow threshold 2 bent around, but spaced out from this.
- overflow threshold 2 and rake 3 The distance between overflow threshold 2 and rake 3 is chosen so that it is a multiple of the expected Thickness of typical amounts of substance retained in the rake is.
- the free ends 3a of the spring steel rake stick out into the coarse material collection area.
- the compliance of the Spring steel rakes is such that when swung down Rake on the edge of the coarse material collection area in contact and be guided past this for pivoting can.
- the lifter is arched and through the bottom Overflow threshold 2 defined in its course while it is fixed above by a cover 11, which is just below the articulation 9 of the rake on the protruding from the partition Poor 10 is articulated.
- the cover 11 is off formed and on a sheet metal piece of suitable thickness the outside shaped so that an emergency holdup is realized is.
- the linkage 9 of the rake and the linkage of the hood is located below the water surface in the event of an overflow. Drainage openings are provided around the articulation area to drain in dry conditions.
- a baffle 13 is located near the inflow area of the lifter 4 realized.
- float exit 4a there is a float-controlled flap Prevention of backflow of water provided in their two end positions is shown. It is so high that it is open during typical events and only closes, if water from the receiving water to the valve-controlling Float arrives.
- a handle 14 at the lifter exit edge provided to pivot the hood in during maintenance To facilitate opening position.
- Fig. 3 shows details of the articulation of the hood and rake.
- Water is used in the usual way through what is used here as a channel Rain overflow structure led to the sewage treatment plant. Now increases due to a rain event the level in the rain overflow structure 5, the water is initially in the usual way pour over the threshold.
- the threshold from below the water flowing into the baffle wall initially only so little, that the entire hood of the jack has not yet been filled with water is.
- the water overflow arrangement 1 of the present The invention thus initially works without responding to a lifting action as a free-flow system.
- Coarse substances are retained in the rake 3 and by the amount of water flushed into the coarse material collection area 6.
- the water flows initially at low levels and / or currents largely through the sections near the coarse material collection area of the rake 3.
- Coarse materials initially collect there without being moved to be able to, since the float-controlled flap 8a on the Drain opening 8 at correspondingly high water levels in the Channel at which the overflow threshold responds closes.
- By bending the rake 3 around the edge 6a of the Coarse material collection area 6 is largely free of rakes here held by coarse materials, as these fall into the collection area can.
- the rain overflow structure will eventually be used up so far that the float-controlled Emptying flap opens and the in Coarse matter collection area collected coarse matter in the rain overflow structure flow out.
- the water overflow arrangement of the present invention is as shown, formed so that there is little danger the pollution exists. Pollution can be used for maintenance be checked by opening the cover on the handle 14 becomes; at the same time it is then possible to fold up of the rake to clean it from the upstream side.
- Fig. 2 shows a variant in which the coarse materials are not included are retained in a coarse material collection box and moreover emptying not through a float-controlled emptying opening towards a rain overflow structure, but via a coarse material collection channel of a coarse material pump or be supplied to a throttle body.
- FIG. 4 shows a variant that largely corresponds to that of FIG. 1 equivalent. Again there is a screen inside the lifter articulated arranged.
- the articulation point 9 is, however, in the 4 shown embodiment arranged much higher, namely, as preferably possible, at or near to Peak of the cover hood. This arrangement is therefore an advantage because it also works with floating coarse materials like Styrofoam u. The like. Raising the rake bars or plates more securely can be avoided.
- Fig. 5 shows a variant in which several rows of rakes are arranged one behind the other. This is particularly advantageous if the distances between the rake bars within each other a series can then be varied and in particular the upstream, i.e. input-side rake bars have a greater distance from each other than the downstream and thus output rods. This arrangement leads to that coarse matter of different extent at different Rows get stuck. So an overall blockage the rake arrangement or water overflow arrangement better avoided.
- rulers with different cross sections used for the different embodiments can be. So it is possible to use round bars, square bars or trapezoidal rods, the latter in particular with the upstream side to provide the widest cross-sectional area. Alternatively, you can Sickle plates are also provided to the slide bars form.
