Definitions

  • the present invention relates to a heavy sludge sorter according to the generic term of Claim 1.
  • Such a sludge sorter except that the diffuser base plate has a plurality of Bores with individual nozzles arranged in them having a nozzle channel and the nozzles each provided with the appropriate check valve are known from DE 36 39 044 C1.
  • a conventional heavy pulp sorter becomes a homogeneous one Upflow through a rubber plate provided with nozzles generated, which is used for mechanical stabilization located between two steel sheets, both Steel sheet corresponding recess holes exhibit.
  • the use of such a rubber sheet has the disadvantage that this is due to mechanical Tolerances of these Holding devices, e.g. the steel sheets, deformed or is not held stable. This puts the pressure on the entrance side of the rubber plate is no longer even distributed and the uniformity of the upstream disturbed.
  • Such a rubber sheet is also very susceptible against mechanical stress and in the event of a mechanical defect must cover the entire rubber sheet to be replaced. Furthermore, the manufacturing such rubber sheets expensive because the mechanical Bracket, i.e. both steel sheets between which themselves the rubber plate is located, with recess holes must be provided.
  • One with a diffuser base plate with single nozzles provided heavy sludge sorter has the advantages that the individual nozzles are independent of the manufacturing tolerances always with the diffuser base plate even pressure are applied so that a constant upflow is always guaranteed.
  • By making a diffuser base plate with Individual nozzles simplify the manufacture of the diffuser base plate, since only one plate is used and only this must be drilled.
  • There a diffuser base plate, for example 1500 holes has a significant reduction of the manufacturing effort.
  • By training the check valve prevents the ingress of sinking material into the pressurized water chamber if the upstream water supply fails prevented.
  • the heavy sludge sorter has a slurry tank 1 with a bottom 31 and an adjoining cylindrical side wall 32 on.
  • the sludge container 1 On the bottom side, the sludge container 1 a diffuser base plate 2, which is in a predetermined Distance from the bottom 31 of the sludge container and extends parallel to it and from the side wall is enclosed.
  • the diffuser base plate 2 has a variety of recess holes in which interchangeable individual nozzles 4 are arranged.
  • the pressurized water chamber 3 is delimited by the base plate 31, which this opposite diffuser base plate 2 and the cylindrical side wall 32. It is characterized by the Base plate 31 extending into the pressure chamber 3 opening upstream water supply line 6 is provided.
  • the heavy sludge sorter has a Discharge device 5 for draining the sinking material.
  • This outlet device is through an outlet line formed by the bottom of the slurry container 1 via the pressurized water chamber 3 into the interior of the sludge tank 1 extends and the inside of the sludge tank 1 a valve controllable via a valve rod 8 having.
  • the valve rod 8 extends through the sludge container 1 up to its top side 9.
  • the slurry container also has a ceiling a material feed device 14 and one Light goods drain 10. Furthermore are on the side walls Displacement claws 15 for holding the slurry container arranged.
  • the individual nozzles 4 of the diffuser base plate 2 is in a bore 30 the diffuser base plate 2 arranged.
  • the nozzle body 18 here has a first cylindrical Section 33 and a subsequent second Section 34 on.
  • the first section is cylindrical. Its outside diameter is dependent selected from the inside diameter of the bore so that the first section with a snug fit in the diffuser baseplate 2 sits.
  • the adjacent second section is closed its end facing away from the first section divergent as a truncated cone.
  • the nozzle body 18 engages with its first section 33 in the diffuser base plate 2 and shows on one protruding portion of the diffuser base plate Thread on.
  • the nozzle is over a nut 20 and one between the diffuser base plate 2 and the nut 20 arranged sealing disc 21 in the diffuser base plate locked.
  • Reference numeral 19 denotes one Sealing or adhesive surface.
  • nozzle channel 17 which on the the side facing the inside of the sludge container, i.e. a narrowing on the outlet side, i.e. one Has nozzle neck.
  • the second section has a cap 16 overdrawn.
  • This cap 16 is made of elastic material formed and sitting under tension on the second Section and has the function of the check valve.
  • the cap 16 is centered in the Cap 16 and over the outlet opening of the nozzle channel 17 arranged a crossed slot 22 which many times larger than the diameter of the outlet opening of the nozzle channel 17. That slit acts as a check valve and blocks the passage of liquid through the nozzle 4 from the sludge tank 1 in the Pressurized water chamber 3.
  • liquid passes from the pressurized water chamber 3 into the turbidity tank 1 opens the check valve.
  • Fig. 4 shows a further embodiment of the Nozzle base body 18.
  • the Nozzle base body made of plastic, but can just like in the above design made of steel or other materials.
  • the one in the diffuser floor 2 engaging first section 25 is as Spreading body formed.
  • the first section 25 is biased and by the expansion effect in the bore locked.
  • a second section 35 is provided to which analogous to the previous embodiment a cap forming the check valve is attached is.
  • FIG Nozzle differs from the previously shown embodiments in that the check valve is not formed in the form of a cap to be put on. Instead, the second section 37 faces on the outlet side Side one coaxial with the nozzle channel arranged recess into which a plate 38 elastic material is glued, which is coaxial to the Center axis of the nozzle channel a cross-shaped Has slot 40, which is best seen in FIG. 6 is.
  • the nozzle body differs 27 of the previous ones in that the first section on its side facing away from the second section End 29 is slotted like a dowel, so that it is elastically compressible. Further points the outside of the first section an undercut 39 on whose outer diameter in substantially equal to the inside diameter of the Nozzle body receiving bore in the nozzle bottom 2, and its expansion in the axial direction of the nozzle channel is equal to the thickness of the diffuser base plate 2 is. Numeral 28 denotes a by the undercut 39 formed pawl.
  • the second section of the nozzle body is cylindrical educated. On this second section is like in the previously described embodiments Plastic cap attached to her on the Cap opening the elastic opening Cross-slotted section.
  • the nozzles via line 6 with pressurized Water is applied so that the water passes through passes through the check valves described above. However, if the water supply is blocked, they go Elastic sections divided into a cross slot shape their starting position back and thus form a check valve.
