Definitions

  • the invention relates to a pressure sorter according to the preamble of claim 1 and to a use of a pressure sorter according to claims 13 and 15.
  • Pressure sorters are used in the processing of paper fiber suspensions, in order to process the pulp suspension in a wet sieving.
  • a pressure sorter contains at least one screen, which is provided with a plurality of openings.
  • the fibers contained in the suspension are to pass through the openings, while rejecting the unwanted solid constituents thereto and are led out of the sorter again.
  • sorting holes round holes or slots are usually used.
  • pressure sorters of the type considered here are equipped with screen scrapers that are moved close to the screen. As a result, clogging of the screen openings is prevented in a manner known per se.
  • the separation effect of a pressure sorter is therefore attributable to the fact that at least some of the impurities contained in the paper pulp suspension fed can not pass through the sieve, that is to say it is separated from the paper fibers due to its size, shape or flexibility.
  • pressure sorters are known in which additionally targeted to the density of the impurities separation is made by the different forces of the impurities are used in a centrifugal field.
  • the separation effect can only be optimally achieved in hydrocyclones and centrifuges, it can still be useful in pressure sorters. Although a large part of the heavy parts would not pass through the screen openings usually used, so be rejected there, but there is a risk of damage or wear when they come into contact with the sieve. This risk is aggravated by the fact that almost always used are Sieblusterr that move very close to the screen at a relatively high speed.
  • pressure graders which in highly contaminated paper fiber suspensions be used by upstream hydrocyclones, so-called thicker scavenger, to protect against coarse heavy particles. This is effective, but with additional effort.
  • Another way to reduce wear on the screen of the sorter is to place the sifter on the accept side of the screen.
  • the rejected parts on the screen have a lower speed and can not be detected by the sieve scraper.
  • the damage caused by pinching of metal parts between the sieve and Siebêtrn is very unlikely.
  • the invention is based on the object of further improving the known pressure sorters, so that even a considerable part of the contaminants can be removed from the paper fiber suspension before they strike the screen. In particular wear-promoting heavy parts and sensitive lightweight parts should be removed early.
  • the inlet chamber This is generally annular and is supplied by a tangentially attached inlet with the pulp suspension to be sorted, whereby a rotational flow is formed.
  • the heavy parts are thrown radially outward, so that they can not or hardly come into contact with the sieve. They drive in the direction of the inner wall of the housing and are partly further dragged by the suspension flow and partly transported by gravity into a part of the Zulaufraumes, from which they can be easily removed.
  • FIG. 1 A typical embodiment of the pressure sorter according to the invention is shown in FIG. 1.
  • This contains in a housing 2 a sieve 1 in the form of a cylindrical screen basket.
  • the center line of the screen 1 is perpendicular here in the position of use of the device.
  • the sieve openings are advantageously cylindrical along their entire length with a diameter between one and three millimeters.
  • the pulp suspension S to be screened is introduced into the housing 2 through an inlet 8. In the process, it first passes into the inlet space 4, which extends substantially annularly and radially outside the screen 1 as part of the housing 2.
  • the inlet 8 is connected tangentially to the inlet chamber 4, so that a rotational flow forms during operation of the machine in the inlet chamber 4, which runs in the clockwise direction in this illustration.
  • the supplied pulp suspension S moves in the inlet space 4 helically downwards, with a considerable part of this suspension pass through the sieve opening of the sieve 1 and can reach into the accepts space 3 located radially inside the sieve 1.
  • a conically tapering portion 15 of the inlet chamber 4 the peripheral velocity of the suspension is maintained or increased, even if their amount decreases due to the outflow through the wire 1.
  • the fibrous suspension S to be screened is contaminated not only with heavy but also with light parts, which include, in particular, polystyrene or other light foams. These are quickly separated from the heavy parts due to the centrifugal forces and can be removed early because they move due to their tendency to rise in the liquid-filled feed space 4 in the upper part. There they are discharged through thechtteilauslass 11. This can, as here, lead vertically upwards or obliquely upwards, or also tangentially connected.
  • an impermeable cylinder wall 14 lying above the screen 1 for the purpose of separating the inlet space 4 and the accepts space 3, so that a lightweight part collecting space is formed in the upper part of the inlet space 4.
  • This can cause a significant calming of the flow, whereby the lightweight parts and possibly air can be separated even better.
  • the axial length of this cylinder wall 14 is only a fraction of the axial length of the screen 1, for example, about 20%.
  • the climbing effect of the lightweight parts can be additionally supported in this area by a fixed helix, which deflects the circumferential movement into a rising motion.
  • reject R The largest part of the suspension rejected at the sieve 1, in particular the contaminants entrained by flow forces, are removed from the housing 2 at the reject outlet 10 as reject R. It is usually sorted to avoid fiber loss.
  • the accepts space 3 has here at its uppermost part a vent line 12 through which air and possibly also very fine lightweight parts can be removed from the accepts.
  • Figures 3 and 4 serve to show even more solutions with specific details.
  • the device according to FIG. 3 has a modified flow guidance in that the accept A from the accept chamber 3 is not discharged downwards, as in FIG. 1, but upwards, ie, that the Gutstoffauslass 9 'is centrally connected to the upper wall of Acceptance space 3.
  • the deducted accepts A then contains in addition to the sorted fibers and air, which is why a further vent line can be omitted.
  • the ejected in the inlet space 4 to the outside heavy parts are guided by a vertical or oblique on the housing 2 radially projecting Schwerteilkanal 18 directly down to the heavy section lock 13.
  • the pressure sorter in Fig. 4 is provided with an inlet space 4 ', whose cross section over the axial height is kept substantially constant, since it was dispensed with a tapered portion. Also, a special separate light parts collection space above the screen 1 can be omitted if necessary, to save height.
  • the lightweight parts are immediately dissipated by thechtteilauslass 11.
  • In the lower part of the inlet chamber 4 ' is a downwardly sloping end wall 19, which leads out there arrived heavy parts together with the reject R through the reject outlet 10 from the housing. Conveniently, the reject outlet 10 is connected at the lowest point. Another Schwerteilauslass can then be saved.
  • the end wall 19 may have an arcuate shape.
  • this device is the pre or coarse sorting of dissolved pulp.
  • This may typically be a recovered paper pulp suspension formed in a pulper 21 from recovered paper P and water W and withdrawn through a coarse pulp screen 22, as shown in FIG.
  • a Pulpersieb 22 is kept free by a rotor 23 and usually has holes with a diameter between 10 and 25 mm.
  • the withdrawn by this waste paper suspension is pumped without further screening device via fuel pump 24 into the inlet 8 of an inventively designed pressure sorter. Therefore, this suspension S may be mixed with a larger amount of impurities, which can easily be retained on screen openings whose diameter, for example, in a range between 1 and 3 mm lies.
  • such soiled waste paper suspensions may be prepared in a high consistency pulper or in a downstream open wire disintegrating drum, such as an open sorting drum, and diluted.
  • a dissolving drum that is suitable for the process shows the German patent application DE 197 36 143 ,
