Definitions

  • the first operation consists of placing the waste paper in bulk in devices supplied with water and subjecting them to a first treatment such as to disintegrate the fiber and to allow or effect the separation of large impurities, such as twine, wire, large plastic, etc.
  • the trommels are generally cylinders rotating on a horizontal axis in which are provided shredding bars or balls and which are followed by sieve trommels or separating devices.
  • these trommels operate slowly and with a low flow rate and they provide a mixture with a low concentration of pulp (2 to 3% of dry matter), so that it is then necessary to carry out costly concentration operations.
  • Primary pulpers are generally open cylinder-shaped devices with paddle rotors in the bottom.
  • the rotor is relatively flat and exerts a violent centrifugal action on the material in contact with a perforated bottom or fitted with bars, which causes the material to be shredded, part of which crosses the bottom and is then taken up. by separators or secondary pulpers.
  • the disadvantage of these devices is a low concentration of the material obtained and excessive shredding, which interests not only the fibrous parts to be recovered, but also non-fibrous parts (twine, metal parts, plastics).
  • Certain other pulpers known under the name of "helical” pulpers, comprise a turbine in the form of a propeller with a vertical axis which imparts to the material an axial downward movement followed by a centrifugal movement on a smooth bottom.
  • defibration is carried out by fiber-to-fiber friction, the centrifuged material being sprayed onto relatively immobile material. Little shredding occurs and as a result the contaminants or impurities are preserved and are not divided while the paper is shredded.
  • the concentration obtained in these devices is of the order of 15% of dry matter, which is high enough to allow dilution in the following classification devices.
  • the object of the invention is to remedy these drawbacks and relates to a helical turbine for a pulper making it possible to produce, at lower cost and with greater efficiency, a range of pulpers much more extensive in volume, and in particular allowing the production of small units.
  • the turbine according to the invention intended to be placed on the bottom of a primary pulper 1 of known shape, is formed of a shaft 2 of axis 9 bearing successively, from from the top, several helical discs 3, 4, 5 distant from each other, and at the bottom, several spiral fins 6, 7, 8.
  • the helical discs 3, 4, 5 are wound in a helix or in an archimedean screw around the shaft 2, each disc having an extension at most equal to one complete turn (360 °).
  • the pitch of each of these helical discs is small, the slope ⁇ at the periphery of the disc being of the order of 15 °.
  • the distance AB between two discs, measured along the shaft 2, is, on the other hand, relatively large. It is this distance which determines the height of the flow channel defined by two successive discs. This distance can vary within fairly wide limits.
  • the invention provides that the distance AB is at least equal to 1.5 times and preferably of the order of 2 times the pitch of a disc.
  • the shape of the spiral fins 6, 7, 8 is particularly visible in Figure 4 (view from below).
  • Their general shape is that of blades which develop in a spiral from the tree 2.
  • the curve adopted is that of Bernouilli spiral with constant angle ⁇ between 25 ° and 35 °.
  • the height of the blades 6, 7, 8 preferably decreases from the shaft 2 to their ends, the high point of each fin possibly being close to the nearest helical disc.
  • the number of these fins is preferably at least equal to three. They fit into an external diameter greater than that of the disks 3, 4, 5.
  • the assembly thus formed is part of a general cone or bell angle at the top Y of the order of 60 ° to 80 °.
  • the turbine according to the invention is presented as a shaft carrying a succession of helical washers of increasing diameter placed at a distance from each other and followed by a centrifugal rotor with spiral fins.
  • the turbine of the invention makes it possible to work at higher concentrations which can reach more than 20%, that is to say more than 200 gr. dry matter per liter, which increases its defibrating power.
  • the manufacturing price of the turbine according to the invention is 4 to 5 times lower, which is considerable.
  • the turbine according to the invention therefore opens up new development perspectives for this kind of primary pulpers.
  • the turbine comprises two helical disks 3, 4 offset by approximately 180 °, while in the example in FIG. 3, three disks 3, 4, 5 are provided offset by approximately 120 ° .
  • the offsets adopted are those which give the best balance in rotation taking into account the differences in diameter of the different discs.
  • Each helical disc will preferably not extend beyond a full revolution (360 °) to avoid the formation of a narrow channel and the resulting jamming.
  • the discs can be more fragmented and extend at a much smaller angle.
  • a washer 10 for supporting the fins 6, 7, 8 is advantageously provided.
