Definitions

  • FIG. 1 shows a longitudinal section of a mixed water collector in which the dry weather water level ( 18 ) lies below the fabric filter web ( 1 ) and the weir upper edge ( 26 ) has been raised to the maximum water level position (7).
  • a relief system ( 25 ) is arranged between the inlet-side inspection shaft axis "AA” and the outlet-side inspection shaft axis "DD” in the region of an axis "CC” displaced off-center in the direction of flow ( 27 ). It can be seen how the fabric filter web ( 1 ) in the slide rails in the defined channel area ( 3 ) ( 2 ) should be retracted and locked.
  • the entire fabric filter web ( 1 ) consists of several individual surfaces ( 20 ) which are connected to one another by means of point connections ( 21 ) and ultimately in the start area ( 4 ) or in the end area ( 5 ) via a corresponding curve formation ( 6 ) up to the maximum water level ( 7 ), which means that the entire relief space ( 23 ) can only be covered with filtered mixed water in the event of a dam.
  • Fig. 2 shows a longitudinal section of a mixed water collector in the relief state, in which the maximum water level position ( 7 ) in the constructive entrance area ( 4 ) was assumed.
  • the indicated relief activity by lowering the upper weir edge ( 26) of the controllable weir ( 24 ) lowers the energy line in the area of the relief system ( 25 ) by the differential pressure ( 28 ), which results from the sum of the pipe friction losses and filter resistances, etc.
  • the arching of the fabric filter web ( 1 ) shown, which ultimately reveals the flexing effect and the resulting self-cleaning of the fabric filter web ( 1 ).
  • Fig. 3 shows a cross section of the mixed water collector "CC" in which the sensible arrangement of the fabric filter web ( 1 ) can be seen within the relief system ( 25 ).
  • the controllable weir ( 24 ) is lowered and is in the so-called relief case, with excess waste water being drained off towards the receiving water.
  • the wastewater flows through the fabric filter web ( 1 ) due to the differential pressure ( 28 ) occurring from the different absolute water levels in the sewer and relief chamber ( 23 ) and thus creates an upward curvature of the fabric filter web ( 1 ), which ultimately results in the flexing effect becomes recognizable.
  • the floating baffle ( 22 ) has the task of holding back any light material in the mixing system that has passed through the fabric filter web ( 1 ). Furthermore, it can also be seen that in the weir area ( 9 ) of relief systems ( 25 ) at least one slide rail ( 2 ) must always be locked below the fixed weir edge ( 29 ), so that a seamless reduction of sievable dirt loads from mixing systems or mixed water clarifiers can be made possible.
  • Fig. 4 shows a cross section of the mixed water collector "AA" in the direction of flow ( 27 ), in which the sensible locking of a fabric filter web ( 1 ) by means of its side edges ( 11 ) located tensile sliding elements ( 13 ), which in turn within the parallel slide rails ( 2 ), here designed like half rails, are drawn in and are subject to a reversible arrangement. Furthermore, it can be seen that the fabric filter web ( 1 ) is pulled up to the maximum water level position ( 7 ) by means of the slide rails ( 2 ) located in the vertical outer wall areas ( 19 ), shown here in broken lines, so that the mixed water quantities flowing to the relief chamber ( 23 ) procedurally differ from those can be exempted from screenable dirt loads.
  • the fabric filter sheet ( 1 ) due to its own weight, has a sag [DH] ( 16 ) in this representation and clarifies the fact of claim 5, according to which the maximum dry weather water level ( 18 ) should normally be below the fabric filter sheet ( 1 ) .
  • Fig. 5 shows a cross section of the mixed water collector "BB" in which the dry weather water level ( 18 ) is below the then sagging by the weight of the fabric filter web ( 1 ), whereby it must be necessary that the width ( 14 ) of the fabric filter web ( 1 ) is greater than that Pipe profile width ( 15 ).
  • a possible variant for reversible locking of the fabric filter web ( 1 ) is shown in detail 3.1, wherein it can be seen that the fabric filter web ( 1 ) has reinforcements ( 12 ) on its edges ( 11 ), on which the tensile sliding element ( 13 ) acts as a slide shoe formed is located within the slide rail ( 1 ).
  • Fig. 6 shows a cross section of the mixed water collector "BB" in which due to a relief by lowering the weir ( 24 ) not shown here or in the case of mixed water accumulation and thus increased inlet water levels, the fabric filter web ( 1 ) is curved upwards. It can be seen here that as a result of the flow through the fabric filter web ( 1 ) from the bottom upwards, reinforcements ( 12 ) with tension-resistant sliding elements ( 13 ) are necessary at their lateral edges ( 11 ) so that a force can be transmitted to the sliding rails ( 2 ) .
  • Fig. 7 shows a top view "EE" a section through the relief system ( 25 ) in which the arrangement of the individual surfaces ( 20 ) of the fabric filter webs ( 1 ) and the arrangement of the eyelet connections ( 21 ) together with the slide rails ( 2 ) is shown.
