Definitions

  • the invention relates to a method according to the preamble of claim 1 and a system for carrying out the method according to the preamble of claim 7.
  • high consistency pulper with the connected dilution devices work overall with interruptions, each time after processing a filling of the high-consistency detergent, the latter is emptied, and after the content has been diluted and possibly cleaned, a new filling is processed.
  • the invention aims to provide a method of the type mentioned which is suitable for continuous work.
  • the method according to claims 4 to 6 is suitable for contaminated raw materials, such as waste paper.
  • Claims 7 to 16 relate to the plant for carrying out the method, and they relate to particularly advantageous and novel details.
  • FIG. 1 shows a system which contains a high-consistency pulper 1 and a mixer 2.
  • the high consistency pulper 1 contains two dissolving elements 5 and 6 driven by motors 3 and 4.
  • the mixer 2 contains a mixing element 8 driven by a motor 7, e.g. a stirring propeller. Behind the mixing element 8 there is a sieve 10, which delimits an accepting material space 11, from which an outlet line 12 with a pump 13 leads outwards from the system.
  • the pulper 1 and the mixer 2 are connected by an opening 14 in the lower region of the wall 15 of the high-consistency pulper.
  • the water supply from a line 9 is designated W, the supply of undissolved substance with B.
  • 1 bale B of the undissolved substance with the appropriate amount of water is fed into the high-consistency pulper, so that when the pulp is dissolved, the consistency of the partially dissolved pulp is 10 to 20%. With this consistency, the paper stock is crumbly, i.e. not pumpable with centrifugal pumps.
  • the system according to FIG. 2 serves to dissolve contaminated raw material, e.g. Waste paper.
  • the system according to FIG. 2 is provided with a cleaning circuit which contains a schematically illustrated sieving device 20, e.g. a drum screen with collecting pan 21 for the continuous material and an overflow 22 for the overflow material, which is separated out and deposited.
  • a schematically illustrated sieving device 20 e.g. a drum screen with collecting pan 21 for the continuous material and an overflow 22 for the overflow material, which is separated out and deposited.
  • the screening device 20 is connected to the mixer 2 by a line 23.
  • a line 24 leads from the collecting trough 21 back into the high-consistency solver 1.
  • a line 25 connects the drip pan 21 with an accept material space 26 of the high-consistency fabric solver 1. This is formed in a manner known per se behind a sieve 27, along which the arms of the dissolving member 5 move during operation.
  • An outlet line 28 with a pump 30 leads outward from the accepted substance space 26.
  • the pulp suspension is fed from the interior of the mixer 2 to the screening device 20, in which the existing impurities, such as plastic films, etc., are excreted.
  • the cleaned pulp suspension was fed through line 25 to the accept material space 26 and serves to dilute crumbly fibrous material which passes from the high-consistency material dissolver 1 into the accept material space 26 through the sieve 27.
  • the pulp suspension obtained is discharged through line 28.
  • the system shown in FIG. 2 can be operated in such a way that the part of the sieve pass of the sieve device 20 which is returned through the line 24 into the high-consistency pulp solver represents its only supply of water which serves to dissolve the bales B.
  • the excess sieve pass ie the diluted pulp suspension, passes through line 25 into the accept material space 26 and out of this through line 28 as accept material to the outside.
  • Water can be added as required through a connection 29, a centrifugal pump 30 ensuring good mixing of the water with the paper stock suspension from line 25 and with the diluted, originally crumbly material which has passed through the sieve 27 into the accept material room 26 .
  • the housing 16 of the mixer 2 at the location of the opening 14 has a larger diameter E than the diameter D of the opening 14.
  • an annular flow of the already diluted paper stock suspension around the crumbly material penetrating through the opening 14 is formed, which is thereby prevented from flowing back into the high-consistency pulp remover 1.
  • the housing 16 is designed such that it tapers away conically from the opening 14. This supports a circulating flow in the housing 16 in its axial plane.
  • the mixer 2 is preferably firmly connected to the high consistency pulper 1 as a mechanical unit, e.g. by welding the housing 16 to the housing 15 of the pulper 1.
  • the size of the opening 14 is selected so that it allows the installation and removal of the mixing element 8 and, in the embodiment according to FIG. 1, of the sieve 10 from the pulper 1 allows.
  • FIGS. 3 and 4 show possibilities for controlling the movement of the crumbly substance from the material dissolver 1 into the mixer 2.
  • the opening 14 is assigned an adjustable flap K, which, depending on its position, more or less supports the movement by deflecting a larger or smaller part of the circulating flow U into the opening 14, or the flow from the pulper 1 in the mixer 2 brakes (position K ⁇ in Figure 3).
  • an opening screw S is assigned to the opening 14, which can run faster or slower as required and thus accelerates or slows down the flow from the pulper 1 into the mixer 2.
  • this figure shows a mixer 2 with a vertical axis, which can also be provided within the scope of the invention.
  • the second dissolving element 6, which supports the circulating flow of the crumbly substance and is shown in FIGS. 1 and 2, can be omitted.
