Definitions

  • the invention relates to a pulper with a screen plate, a stirrer arranged above, a first outlet above the screen plate and a drain below the screen plate. Moreover, the invention relates to different methods for using such a pulper.
  • Such pulpers are used for the treatment of paper residues, biological materials and a variety of other substances.
  • the substances are subjected to a grinding process and it different fractions are separated.
  • the separation of the fractions is done on the one hand by the arrangement of the processes and on the other hand, the design and arrangement of the screen plate.
  • the invention has for its object to further develop such pulpers and to provide methods for using such a pulper.
  • This object is achieved in that it has a pressurizable closed space. This allows it above the Liquid surface in the pulper to use an air cushion with an overpressure of 0.1 to 0.5 bar, such as 0.2 bar.
  • the pulper has a pulper vessel which can be filled to a level and the inlet and outlet extend in a region above this level.
  • the liquid column in the inlet and in the outlet can serve to provide an overpressure in the pulper.
  • the screen plate has holes with an area the size of a circular area of 0.1 to 0.5 mm.
  • the arrangement of balls above the screen plate causes these balls to accelerate the processes in the pulper.
  • Some of the balls have the function of a ball mill. However, depending on the size, weight, and material of the balls, the balls will give further positive results during treatment of residuals in the pulper.
  • the balls do not float in the pulper, they should have a specific gravity that is above 1.
  • the specific gravity may be less than 1, since the balls with the stirrer can also be conveyed into the material to be ground against their buoyancy.
  • spheres having a specific gravity between 1.3 and 1.8 Particularly good results were achieved with spheres having a specific gravity between 1.3 and 1.8.
  • spheres of PVC with a specific gravity of about 1.4 are particularly suitable for the processes in the pulper.
  • the balls may have a lenticular or even angular surface. Depending on the application, the surface of the balls can be varied become. However, particularly good results were achieved with a spherical spherical shape.
  • the screen plate has a flat perforated plate.
  • the pulper can thereby be used for de-staining, painting and sorting.
  • the perforated plate has slots.
  • commonly used slotted plates can be used in the field of use of pulpers.
  • slits with a width of 0.1 to 0.2 mm and a length of one to several centimeters are suitable.
  • the object of the invention is also achieved with a use of such a pulper, in which chips and accompanying substances are treated in the pulper with the balls and the stirrer, in a hydrocyclone the balls are separated and the balls are returned to the pulper.
  • This process is preferably operated continuously to allow effective rapid treatment.
  • the pulper is particularly suitable as a deflaker and as a defibrillator.
  • FIGS. 1 to 5 Embodiments of various pulpers are in the FIGS. 1 to 5 shown. Only the Figures 5 and 7 Inventive embodiments.
  • a pulper 1 has a screen plate 2 and a stirrer 3 arranged above it.
  • the stirrer 3 has a central spiral 4 and radially arranged Paint elements 5, 6 which interact with counterparts 7, 8 on the pulper vessel 9.
  • the spiral increases to a stirring element 10, which serves to stir the arranged in the pulper balls 11 above the screen plate.
  • passing fibers can be removed through the tube 12, while various fractions can be deducted from above the screen plate 2 accumulating fibers through the screw tubes 13, 14 and 15, to optionally also the pulper can be added again.
  • a slider 16 makes it possible to remove accumulating residues from the pulper on the screen plate.
  • FIGS. 2 and 3 Various arrangements of the spiral tubes are in the FIGS. 2 and 3 shown. While in FIG. 2 with two arranged at different heights screw tubes 17, 18 residues can be removed from the pulper, shows the FIG. 3 two screw tubes, of which a screw tube 19 removes residues up, while the other screw tube 20 removes residues down.
  • FIG. 4 shows an alternative embodiment of a pulper 30 in which also in the edge region a grinder 31 is provided to between moving wings 32 and a static wall 33 a To produce grinding process. This grinding process is still supported by 35 arranged above the screen plate balls 35.
  • pulper 40 is replaced by a cover 41 of a similar to that in FIG. 1
  • Pulpers shown in Pulpergefäß 42 allows pressure adjustment.
  • a negative pressure in the pulper can be generated in order, for example, to counteract the drawing in of air toward the screen plate.
  • an overpressure can be generated.
  • the pressure is displayed with the manometer 43.
  • the supply and discharge lines 44, 45 are extended upward such that the liquid level in the lines can be varied in a particularly wide range. The liquid level in the lines can thereby also be above or below the liquid level in the pulper.
  • FIG. 6 shown embodiment of a pulper 50 therefore has a vertically arranged discharge line 51 with a built-head coil as Begleitaustragswitzl 52. This results in a very compact and thus inexpensive arrangement is achieved.
  • the spiral 53 at the bottom 54 of the pulper 50 leads to a particularly favorable filling of the accompanying discharge spiral 52.
  • the arranged at the upper end of the accompanying discharge spiral 52 horizontal coil 55 allows further transport and ejection into a container, not shown.
  • Pulper 60 shown is essentially like the pulper in FIG. 5 built up. However, in order to avoid entrainment of air during stirring, a tube 62 was attached above the pulper vessel 61. As a result, the water column above the screen plate 63 can be increased and a funnel formation during stirring can be reduced. At the upper end of this tube 62 is a Windkessel 64, which in turn can be kept under pressure with a line 65. The pressure displayed on the pressure gauge 66 can thereby be easily regulated.
