Definitions
- the present invention relates to a Schwertrübe ⁇ sorter according to the preamble of claim 1.
- Such a heavy pulp sorter is known from DE 36 39 044 Cl.
- a homogeneous upflow is generated by a rubber plate provided with nozzles, which is located between two steel sheets for mechanical stabilization, both steel sheets having corresponding recess bores.
- the use of such a rubber plate has the disadvantage that it is deformed due to mechanical tolerances of the holding devices holding it, such as the steel sheets, or is not held stably. As a result, the pressure on the inlet side of the rubber plate is no longer evenly distributed and the uniformity of the upstream flow is disturbed.
- such a rubber plate is very susceptible to mechanical stress and in the event of a mechanical defect, the entire rubber plate must be replaced.
- a heavy sludge sorter provided with a diffuser base plate with individual nozzles has the advantages that the individual nozzles are always subjected to uniform pressure regardless of the manufacturing tolerances of the diffuser base plate, so that a constant inflow is always guaranteed.
- the manufacture of the diffuser base plate is simplified, since only one plate is used and only this has to be provided with bores. Since a diffuser base plate has, for example, 1,500 bores, this represents a considerable reduction in the production outlay.
- the design of the check valve prevents the sinking material from penetrating into the pressurized water chamber if the upflow water supply fails.
- FIG. 2 shows an embodiment of the exchangeable individual nozzle for the heavy sludge sorter according to FIG. 1,
- FIG. 3 shows an embodiment of the non-return device of the individual nozzle according to FIG. 2
- 4 shows a further embodiment of the basic nozzle body of the exchangeable individual nozzle for the heavy pulp sorter according to FIG. 1,
- FIG. 5 shows yet another embodiment of the exchangeable individual nozzle for the heavy sludge sorter according to FIG. 1,
- FIG. 6 shows an embodiment of the non-return device of the individual nozzle according to FIG. 5,
- FIG. 7 shows a further embodiment of the individual nozzle for the heavy sludge sorter according to FIG. 1.
- the heavy sludge sorter has a sludge container 1 with a bottom 31 and an adjoining cylindrical side wall 32.
- the slurry container 1 On the bottom side, the slurry container 1 has a diffuser base plate 2 which extends at a predetermined distance from the base 31 of the slurry container and parallel to it and is enclosed by the side wall.
- the diffuser base plate 2 has a plurality of recess bores in which exchangeable individual nozzles 4 are arranged.
- a pressurized water chamber 3 is arranged under the diffuser base plate 2.
- the pressure water chamber 3 is delimited by the base plate 31, the diffuser base plate 2 opposite this and the cylindrical side wall 32.
- An upflow water supply line 6 which extends through the base plate 31 and opens into the pressure chamber 3 is provided.
- the heavy sludge sorter has an outlet device 5 for discharging the sinking material.
- This outlet device is formed by an outlet line which extends through the bottom of the sludge tank 1 via the pressurized water chamber 3 into the interior of the sludge tank 1 and which has a valve which can be controlled via a valve rod 8 in the interior of the slurry tank 1.
- the valve rod 8 extends through the slurry container 1 to the top side 9 thereof.
- the sludge container furthermore has a material feed device 14 on the ceiling side, as well as a light material outlet 10. Furthermore, displacement claws 15 for holding the sludge container are arranged on the side walls.
- the single nozzle 4 is arranged in a bore 30 of the diffuser base plate 2.
- the nozzle base body 18 here has a first cylindrical section 33 and a second section 34 adjoining it.
- the first section is cylindrical. Its outer diameter is selected as a function of the inner diameter of the bore such that the first section fits snugly in the diffuser base plate 2.
- the adjoining second section is designed as a truncated cone towards its end facing away from the first section.
- the nozzle base body 18 engages with its first section 33 in the diffuser base plate 2 and has a thread on a section protruding from the diffuser base plate.
- the nozzle is locked in the diffuser base plate via a nut 20 and a sealing washer 21 arranged between the diffuser base plate 2 and the nut 20.
- the reference numeral 19 denotes a sealing or adhesive surface.
- a nozzle channel 17 runs essentially coaxially to the bore in the main body of the nozzle, the nozzle channel 17 on the side facing the interior of the turbid container, i.e. a narrowing on the outlet 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 function of the check valve.
- the cap 16 has a crossed slot 22 arranged in the center of the cap 16 and above the outlet opening of the nozzle channel 17, which slot is 22 times larger than the diameter of the outlet opening of the nozzle channel 17.
- This slot acts as a check valve and blocks the passage of liquid through the nozzle 4 from Turbidity tank 1 in the pressure water chamber 3. When liquid passes from the pressure water chamber 3 into the turbidity tank 1, the check valve opens.
- Fig. 4 shows a further embodiment of the nozzle base body 18.
- the nozzle base body is made of plastic, but can be made of steel or other materials exactly as in the above embodiment.
- the first section 25 engaging in the diffuser base 2 is designed as an expansion body. By introducing the nozzle body into the diffuser base plate 2 up to the stop surface 24, the first section 25 is prestressed and locked in the bore by the spreading action. Adjacent to the first section, a second section 35 is again provided, onto which a cap forming the check valve is placed analogously to the previous embodiment.
- 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. Instead, the second section 37 on the outlet side has a recess which is arranged coaxially to the nozzle channel and into which a plate 38 made of elastic material is glued, which has a cross-shaped slot 40 coaxially to the center axis of the nozzle channel is best seen in Fig. 6.
- the nozzle body 27 differs from the previous ones in that the first section is slotted at its end 29 facing away from the second section in the manner of a dowel, so that it can be elastically compressed. Furthermore, the outside of the first section has a Undercut 39, the outer diameter of which is substantially equal to the inner diameter of the bore in the nozzle base 2 receiving the nozzle body, and the extent of which in the axial direction of the nozzle channel is equal to the thickness of the diffuser base plate 2.
- Reference numeral 28 denotes a holding pawl formed by the undercut 39.
- the second section of the basic nozzle body is cylindrical.
- a plastic cap is placed on this second section, which has the elastic section with a cross recess on its cap bottom resting on the nozzle opening.
- the nozzles are pressurized via line 6 with water under pressure, so that the water passes through the check valves described above. If, on the other hand, the water supply is blocked, the elastic sections divided into a cross-slot shape return to their starting position and thus form a check valve.
