Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the fibrous suspension intended for paper production must in many cases be cleaned of debris contained therein - so-called contaminants. This applies in particular to waste paper processing.
  • Hydrocyclones are capable of concentrating and extracting heavy particles in pulp suspensions by centrifugal forces. As a rule, they are used to remove metal parts, broken glass and stones. The substances or parts removed from the suspension in this way can be brought out of the closed system by attaching a heavy-duty lock to the corresponding devices. How such a discharge device works, is known per se: It generally has two shut-off devices, such as a first and a second slide, between which there is a lock chamber. As long as the first slide, which establishes the connection between the lock chamber and the system guiding the suspension, is opened, the lock space fills continuously with the waste to be removed.
  • the invention is based on the object to reduce the wear by rotating heavy parts.
  • connection part preferably in cooperation with an added liquid (for example return water from the system), a gradually decelerating rotational flow is formed, which absorbs the suspension flowing in from above.
  • an added liquid for example return water from the system
  • the sinking heavy parts are separated in the connecting part of fibers or pieces of fiber, can easily sink down and accumulate at the bottom. The fibers, however, get with the water in the middle of the connecting part and from there ultimately in the Gutstoffauslass.
  • FIG. 1 shows a section in a lateral view through the connecting part 2 designed according to the invention. Its inner surface 9 is a polygon in the projection, for example a regular quadrilateral. The polygonal cross-section may be constant over the entire axial extent A or as here close to the Schwerteilauslass 4 have a constriction 7, which reduces the cross section there back to a circle.
  • the axial extent A of the connecting part 2 is greater here than the inner diameter of the connecting part 6, preferably 1.5 to 5 times as large.
  • connection 15 for adding liquid F is particularly advantageously arranged in the polygonal region of the connection part 2, e.g. like here in the lower third.
  • the terminal 15 may be connected tangentially.
  • the direction of inflow at the connection 15 can oppose the direction of the rotational flow in the connection part 2.
  • the connecting part 2 is e.g. detachable with screws 14 and thus easily replaceable attached to an overlying cylindrical connecting part 6.
  • a hydrocyclone 3 is shown, which is equipped with the device according to the invention, wherein the connecting part 2 opens into a heavy-duty lock 17 with an upper slide 10 and a lower slide 11.
  • the connecting part 2 is here directly with the hydrocyclone. 3 connected, but it can also be the use of the connection part 6 shown in Fig. 1 are provided.
  • the pulp suspension S is pumped tangentially into the interior of the hydrocyclone 3 via an inlet connection 12 and set in rotation. As a result, the centrifugal forces can be used to separate heavy parts and pulp suspension in the known manner.
  • the cleaned suspension is discharged as accept G through the centrally located Accepts pipe 13.
  • the heavily enriched with heavy particles suspension enters the connected below connecting part 2.
  • the almost fiber-free washed out heavy parts can then pass through the slider 11 in the underlying heavy-lift lock 17.
  • the two slides 10 and 11 are clocked by a corresponding control device, so that the heavy parts can fall at adjustable intervals in the Schwerteil gutter 14.
