Definitions
- the present invention relates to a heavy pulp sorter according to the preamble of claim 1.
- Such a heavy sludge sorter except that the diffuser base plate a plurality of bores with individual ones arranged therein Has nozzles with a nozzle channel and the nozzles each with the corresponding check valve are provided is from DE 36 39 044 C1 known.
- a homogeneous upflow through a rubber plate provided with nozzles generated, which is for mechanical stabilization between two steel sheets is located, both steel sheets corresponding Have recess holes.
- the use of Such a rubber sheet has the disadvantage that this due to mechanical tolerances of the holding devices holding them, such as. the steel sheets, deformed or not is held stable. This puts the pressure on the input side the rubber plate is no longer evenly distributed and the Uniformity of upstream disturbance.
- Rubber plate very susceptible to mechanical stress and im
- the entire rubber sheet must be removed be replaced.
- the manufacture of such Rubber plates are expensive because the mechanical holder, i.e. both steel sheets between which there is the rubber sheet located, must be provided with recess holes.
- One with a diffuser base plate with single nozzles Heavy sludge sorter has the advantages that the individual nozzles regardless of the manufacturing tolerances of the diffuser base plate are always pressurized evenly, so that a constant upflow is always guaranteed.
- the manufacture of the diffuser base plate is simplified, because only one plate is used and only this one Holes must be provided. Because a diffuser base plate for example, has 1500 holes, this represents a considerable reduction in manufacturing costs the design of the check valve will prevent the intrusion of Sink material in the pressure water chamber in the event of a failure of the upstream water supply prevented.
- the heavy sludge sorter has a sludge container 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 has a diffuser base plate 2, which are at a predetermined distance extends from the bottom 31 of the slurry container and extends parallel to it and is enclosed by the side wall.
- the diffuser base plate 2 has a plurality of recess bores, in which interchangeable individual nozzles 4 are arranged.
- a pressurized water chamber 3 Under the diffuser base plate 2 is a pressurized water chamber 3 arranged.
- the pressure water chamber 3 is limited by the Base plate 31, the diffuser base plate opposite this 2 and the cylindrical side wall 32. It is a self extending through the base plate 31 into the pressure chamber 3 opening upstream water supply line 6 is provided.
- the heavy sludge sorter also has an outlet device 5 to drain the descent.
- This outlet device will formed by an outlet pipe that extends through the floor of the sludge tank 1 via the pressurized water chamber 3 into the interior of the sludge container 1 extends and the inside of the Turbidity tank 1 a valve controllable via a valve rod 8 having.
- the valve rod 8 extends through the slurry container 1 up to its top side 9.
- the slurry container also has a material feed device on the ceiling side 14, as well as a light goods drain 10. Furthermore are on the side walls displacement claws 15 for mounting of the slurry container arranged.
- the single nozzle 4 is in a bore 30 of the diffuser base plate 2 arranged.
- the nozzle body 18 has a first here cylindrical portion 33 and an adjoining second section 34.
- the first section is cylindrical educated. Its outside diameter depends on the inside diameter the hole chosen so that the first section sits in the diffuser base plate 2 with a snug fit.
- the adjacent one second section is facing away from the first section End divergent as a truncated cone.
- the nozzle section 18 engages with its first section 33 the diffuser base plate 2 and points to one of the diffuser base plate protruding section a thread.
- the nozzle is via a nut 20 and one between the diffuser baseplate 2 and the nut 20 arranged sealing washer 21 locked in the diffuser base plate.
- the reference number 19 denotes a sealing or adhesive surface.
- the nozzle body runs essentially coaxially to the bore a nozzle channel 17 on the inside of the slurry tank facing side, i.e. a narrowing on the exit side, i.e. has a nozzle neck.
- the second section is covered with a cap 16.
- This Cap 16 is made of elastic material and sits under Tension on the second section and has the task of Check valve.
- the cap 16 has a center in the cap 16 and above the outlet opening of the nozzle channel 17 arranged a crossed slot 22 that many times larger than the diameter of the outlet opening of the Nozzle channel 17 is.
- This slot acts as a check valve and blocks the passage of liquid through the nozzle 4 from Turbidity tank 1 in the pressurized water chamber 3. When passing through of liquid from the pressurized water chamber 3 into the turbidity tank 1 opens the check valve.
- Fig. 4 shows a further embodiment of the nozzle body 18.
- the nozzle body is made Plastic formed, but can be just like the one above Design made of steel or other materials his.
- the first section engaging in the diffuser floor 2 25 is designed as an expansion body. By bringing in of the nozzle body in the diffuser base plate 2 to Stop surface 24, the first section 25 is biased and locked in the hole by the expansion effect.
- a second section 35 provided on the analog as in the previous embodiment a cap forming the check valve is attached is.
- the embodiment of the nozzle shown in FIG. 5 differs from the previously shown embodiments in that the check valve is not in the form of a cap to be fitted is formed. Instead, the second section 37 the exit side one coaxial to the nozzle channel arranged recess in which a plate 38 made of elastic Material is glued in, which is coaxial to the central axis of the nozzle channel has a cross-shaped slot 40, which is best seen in Fig. 6.
- the nozzle body 27 differs from that previous in that the first section at its the second section facing end 29 in the manner of a dowel is slotted so that it is elastically compressible. Furthermore, the outside of the first section has one Undercut 39 whose outer diameter is essentially equal to the inside diameter of the nozzle body Bore in the nozzle bottom 2, and its expansion in the axial direction of the nozzle channel equal to the thickness of the Diffuser base plate 2 is. Numeral 28 denotes one holding pawl formed by the undercut 39.
- the second section of the nozzle body is cylindrical. On this second section is the same as that previously described Embodiments put a plastic cap on the cap base on the nozzle opening is elastic Cross-slotted section.
- the nozzles are over Line 6 pressurized water, so that the water through the check valves described above passes through. However, if the water supply is blocked, go the cross-slit elastic sections in their starting position back and thus form a check valve.
