Definitions

  • the present invention relates to a filter stage device for mechanical solids separation from in Channels, channels or channels flowing liquids, which a variety of to a fixed grate connected step rakes and a variety of one movable grate connected step rakes, with the grates inside the flowing liquid starting from a level below the surface in Flow direction arranged inclined and the step rakes in the direction of the incoming flow Are stepped direction, and in which the movable grate with a drive device on a track is actuated, starting from one in vertical and horizontal direction identical to the fixed grate Zero position, one over the steps of the to the fixed Rust connected step rakes and against the incoming flow rising direction rising Lift movement up to at least one with the next higher one Fixed grate level in vertical and in horizontal direction allowed identical position and the Moving grate subsequent level rulers below the fixed grate back to the zero position leads, the fixed grate at least laterally from Frame parts is surrounded.
  • Such devices are known as step rakes and are used within sewage or separation plants to Waste water to discharge existing solids.
  • EP-A-0 098 820 discloses a step filter in which the Drive device is provided on the top of the grids, the movement of the movable grate over a Eccentric wheel and one connected to this eccentric wheel, gripping the fixed grate from above and outside Carrier is transferred.
  • DE-A-40 01 859 discloses a sieve screen for removal of solid components from flowing liquids, at a crank mechanism is arranged below the bars which controls the movement of the movable bars.
  • the selected lever arrangement is based on this Skids from the guide profiles of the supporting structure are stored.
  • WO-A-94/24373 discloses a filter stage rake in which the movable grate eccentrically on the top of a wheel is connected, with this wheel also eccentric a long thin rod is connected, which in turn on other end area is mounted on chains on the frame and thereby a kind of elliptical rotary movement on the moving rust in this area. Because in the area of the upper eccentric connection of the movable grate an essentially circular movement of the individual Steps expires and in the lower area an elliptical Movement expires are over the course of the step rulers different profiles in the longitudinal direction required to have a reliable discharge guarantee. Furthermore, the chain bearing is the Push rod in the lower area with regard to permanent reliable function is not optimal.
  • the invention is based on the state of the art Technology, the task or the technical problem, to propose a step rake in which the for one safe operation necessary space is minimized and at the same time with any steep inclination in the flow direction the passage of even larger solid bodies without Problems.
  • the construction is supposed to simple, robust and low maintenance.
  • the filter stage device according to the invention is by the Features of independent claim 1 given. Beneficial Refinements and developments are through the dependent claims.
  • liquids are characterized by this from that all drive elements of the movable grate in essentially in the by the fixed grate and the movable grate formed in the common zero position Level are arranged.
  • Such a design of the device results in a modular structure in which the entire device including the drive within just by simplest side structures or side support structures limited channel cross sections as ready to use Components can be used and operated without elaborate structures or channels, machine boxes or houses, controls or gear units or Equipment for accessories must be created.
  • the modular structure also allows easy Installation in existing systems, for example with one Wear of the old system necessary replacement of the Computing devices, and is therefore ideal for Adjustment of clot cleaning to approximately in the course of wastewater fractions have changed in recent decades, too to new legal regulations with regard to the further disposal of the treated water.
  • the drive elements advantageously include driven and in a frame of the fixed grate mounted wheels, the movable grate being eccentric and is articulated radially to the wheel axis on the wheels.
  • Such training allows minimization as well as Encapsulation and integration of the drive elements within load-bearing, in particular hollow frame parts, so that such Drive elements also below the water level can be arranged and only easy to seal Rotary unions must be provided.
  • the Drive via chain drives acting on the wheels / cheek / s or cardan shafts.
  • Such a construction supports the compact design and enables safe transfer large forces, which also makes bulky and heavy discharge is easy to handle.
  • Fig. 1 is designed as a step rake 1 Device for mechanical solid separation shown, in which from the side frame parts 3, 4, the upper frame part 2 and the lower frame part 5 existing frame the step rakes of a movable Grate 6 between the step rakes of a fixed Grate 7 are arranged.
  • the electric motor 8 on the top that connects to one Gearbox 9 is flanged.
  • the electric motor 8 with Gear box 9 is at the top of the frame, i.e. at the attached as a frame part 2 and attached drives three via the chain drive 10 shown in FIG. 3 Sprockets 11, 12, 19 on, which are spaced in one plane to each other, essentially parallel along an imaginary one Connecting line to the outer frame part 3, 4 run, are rotatably arranged on the frame part 3, 4.
  • the Sprockets 11, 12, 19 have eccentric cams 17, about the an outer, lateral cheek 13 on both sides of the Frame parts 3, 4 is connected eccentrically.
  • the lateral cheeks 13 are not closer to one shown substructure with the movable step rakes 6 'of the movable grate 6 in connection. By this articulation lead the side cheek 13 and thus also all step rakes 6 'that indicated in Fig. 3 circular movement K through.
  • the step rakes 6 ' are identical to the step rakes 7 'trained and lie - from the side seen - in the zero position completely congruent side by side and in each case between the step rakes 7 '. In The same position is also the side of the outside Cheeks 13. These perform the same movement as that Step rakes 6 'of the movable grate 6.
  • the lateral cheek 13 is in the spherical bearing flanges 14, 15 and 16 mounted, their axes through the eccentric cam 17 'to 17 “' are formed, whereby the movable grate 6 can be actuated on a track K, which, starting from a in the vertical and horizontal direction with the rake bars 7 'of the fixed grate 7 identical zero position, one Lift movement up to at least one with the next higher one Level of the fixed grate 7 in vertical and horizontal Allow for the same position and the slide rules 6 'of the movable grate 6 then below the fixed grate 7 leads back to the zero position.
  • This lifting movement is either to be discharged from the Channel surface or from the bottom of the channel promoted above and by the below the sprocket 19th existing opening 18 to corresponding further Facilities dropped.
  • step rake makes it safe Operation minimized space requirements and at the same time any steep incline in the direction of flow of the passage also allows larger solid bodies without problems.
