Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • Sieves with a cylindrical shape are called sieve baskets. But there are also levels Sieves that serve the same purpose.
  • sieves on the other hand are optimal for fine sorting. This is partly because that the paper fibers that are to pass through the screen in such sorting processes are one have elongated shape while a large part of the impurities are cubic or is flat. When choosing a suitable sieve, always weigh it up between the demands for high throughput and the demanded Sorting quality. Examples of a perforated screen basket are shown in DE 196 35 189 and a slotted screen basket DE 39 27 748 A1.
  • a strainer basket which has relatively narrow slots provided and is essentially intended for fine sorting. These slots Unlike the usual slotted screen baskets, they do not run over the entire axial Extension of the strainer basket, but are divided several times. This is supposed to Sorting quality of the slotted screen basket can be improved. Sieve baskets of this type are especially for the removal of very poorly sorted substances, e.g. Stickies, optimized. As a rule, this is done with a relatively low throughput, based on the entire screen area, bought. Sieves of this type also require a relatively low one Consistency. It should be below 2.5%, if possible around 1.5%. It's different with Perforated screens, which are still with a consistency around and over 3% reliable and let it operate effectively.
  • Sorting quality of the slotted screen basket can be improved.
  • Sieve baskets of this type are especially for the removal of very poorly sorted substances, e.g. Stickies, optimized. As a rule, this is done with a relatively low throughput, based on the entire
  • the screen baskets known from EP 0 455 312 A2 are apparently also available Fine sorting determined. Specific information for preferred examples is included Slot widths well below 1 mm. You can find it elsewhere in Scripture too other information, e.g. from "0.002 inches to 0.35 inches or more" that is 0.05 mm to 9 mm or more. However, that is another area and nothing is said for which use cases which selection should be made.
  • the publication primarily describes methods to create slots or holes, their shape and size are convenient for certain applications. In this context, too explains that with the new manufacturing process, there is also the possibility to produce unusual shapes of screen openings, including a number of examples is enumerated.
  • the invention is based on the object, the method for sorting Fiber suspensions to improve even further, so that without significant loss of Sorting quality the throughput can be increased.
  • FIG. 1 shows by way of example, this can be used to carry out the method strainer 1 used as a cylindrical strainer basket (drawn in perspective) his. It is crucial for the method that the screen openings 3 in the Claims described are formed as elongated holes. Here are only a few elongated holes drawn. As you know, there are sieve baskets that have thousands have such sieve openings. In order to wet sieve a fiber suspension S in the example shown here, this is carried out from above into the Sieve basket formed interior initiated. Part of this fiber suspension S can pass through the screen openings 3 and in this way get into the accept A. Another Part that at least partially consists of the substances rejected at the screen openings 3 exists, is led out from the screen 1 as reject R below.
  • the reamer 4 is provided with wing profiles, of which only one is drawn; as is well known, other shapes are also possible.
  • the scraper 4 will driven by a central shaft 6 and thereby in the indicated by arrow Direction of movement 5 moved past the inside of the sieve. So it's about a screen clearing on the inlet side of the screen, which is particularly effective and at which Carrying out the method is preferred.
  • the screen openings 3 have the shape of elongated holes, as exemplarily something are shown in more detail in FIG. 2. They have a hole width W that is between 1 and 8 mm, and a hole length L between 1 and 50 mm.
  • the hole length L is an advantage at least twice as large as the hole size W.
  • the Distance A the adjacent sieve openings 3 in the direction of their longitudinal extent from each other. Values between 1 and 6 mm are particularly favorable here because they are small enough to allow a sufficiently large open screen area and large enough to prevent long fiber spinning on the screen webs.
  • the shape and size of such sieve openings on the To coordinate the intended use it has been shown that the specified Measuring ranges deliver optimal results when carrying out the method.
  • screen baskets are particularly well suited to the process, if the longitudinal extent of the elongated holes is such that their angle ⁇ to the axial direction 7 of the screen basket is very much larger than 0, preferably over 45 °. 1 and 2 show a shape with an angle ⁇ of 90 °.
  • the alignment of the elongated holes can also be done with respect to Define reamer movement.
  • the drawing shows an angle ⁇ , which, between the Longitudinal extension of the elongated holes and the direction of movement 5 of the reamer 4 measured, here has a value of 30 °.
  • the procedure is in this form carried out, a relatively high long fiber content gets into the accepted material.
  • the so achievable good selectivity of wet sieving is due to the fact that Alignment, size and shape of the screen openings optimally to the requirements of a Wet fiber screening are matched.
  • flat sieves can also be used, as they are e.g. are used in suitably designed sorting apparatus.
  • conceivable Applications are also secondary substance dissolver and pulper machine.
  • An example for DE 2345735 shows a secondary pulper.
