    A process for washing fibre stock. The fibre stock is described is passed along a passage 14 from a stock inlet 15 to a stock outlet 16. The passage is defined by a portion of the inner surface of a substantially horizontal cylindrical screen 4, preferably a wire gauze. Washing liquid such as water is introduced into the passage, preferably by means of apertures 9 in a longitudinally extending hollow member 8. Effluent liquid passes through the screen, for extraction e.g. through outlets 24 and 25. To enable the washing of stock of high consistency e.g. up to 8%, while avoiding plugging of the screen 4, the arrangement is such that the stock only partially fills the cylindrical screen and is subjected to a tumbling action by the rotary movement of the cylindrical screen as the stock moves along the passage 14 to the stock outlet 16. The hollow member 8 is displaced downwardly from the axis of the cylindrical screen, so as to be positioned within the tumbling stock. In an alternative arrangement, the screen is defined by an endless belt carried over a series of rollers and having a portion of upwardly concave cross-section.

    The invention is directed to methods and devices for washing fibrous raw materials in the production of paper waste paper.
    There is a known method of washing the fiber raw material, mainly paper waste paper with printing ink, by mixing the raw material with a concentration of 2-8% from the inlet side of the cylindrical filtering screening sieve to its output, supplying the washing liquid and processing the raw material with a radial jet of liquid. from the input of the washing liquid and the area of the sieve in the direction of its longitudinal axis, and removal of the filtrate 1.
    A device for carrying out this method is also known, comprising a housing with a cylindrical filtering system longitudinally located therein; a sieve, a means for supplying fiber raw materials from one SIDE of the sieve and a means for discharging the processed raw materials from the other side, a tubular perforated, a liquid dispenser installed inside the sieve and longitudinally extending along its sorting section, a filtrate removal means 1.
    The known device does not provide an effective washing of the raw material of dense consistency.
    The purpose of the invention is to increase the efficiency of the process.
    The goal is achieved by the fact that according to the method of washing the fiber raw material, mainly paper waste paper with printing ink, by moving the raw material with a concentration of 2-8% from the input side of the cylindrical filtering screen
    the sieve to its outlet, supplying the sludge fluid and treating the sludge with radial jets of liquid in a place away from the washing liquid inlet, and a portion of the sieve in the direction of its longitudinal axis and draining the filtrate, the raw material is moved from the inlet side to the outlet side of the immersed in raw materials, and subjected to tilting at a sieve velocity of 0, 5 5 - {D.m / s, where D is the diameter of the sieve, the radial jets of the washing liquid are supplied to the sieve zone located below its longitudinal axis, and the filtrate is discharged from sieve pieces immersed in raw materials.
    The sieve is filled with raw materials for at least 10-60% of its volume.
    In addition, in a device that connects a housing with a cylindrical filtering screen sieve arranged longitudinally therein, means for delivering fiber raw materials from one side of the screen and means for discharging the processed material — On the other hand, a tubular perforated wash liquid distributor installed inside the screen and longitudinally passing sieve, along the sorting section, the filtrate removal means, the sieve has at least a part located horizontally and its surface is bent downwards in
    direction from the longitudinal axis, and
    a drive for rotating it around the longitudinal axis, and a tubular wash liquid distributor fixedly mounted and displaced in the radial direction downward from the longitudinal axis
    sieve and located at a distance of 0.05-0.3 diameter sieve from its axis. The filtering screening sieve is made in the form of an endless filter belt with guide rollers. On. 1 shows a device explaining the proposed method, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 — proposed device, embodiment; in fig. 5 shows a section B-B in FIG. 4 .. The device contains the case 1c PROBLEM: located - In it is a cylindrical filtering sorted sieve 2. Sieve 2 has end plates 3 and 4 and wire mesh.-5. ; -, . ....-. Inside the screen 2 there is a tubular perforated distributor for the industrial fluid, which extends longitudinally along the screening section 7, fixed still, 1 cm radially downward, from the longitudinal axis of the screen 2 and located at a distance of 0.05-0.3 of the diameter of the screen axis. In addition, said distributor 6 is made of two parts 8 and 9 with a separating partition 10. The end plates 3 and 4 of the sieve 2 have cylindrical flanges 11 and 12 with which the sieve rests on the rolls 13 and 14. The sieve 2 is rotated from drive (not shown). On one side of the screen 2 is a means for feeding the fiber raw material, and the other is a means for discharging the spent raw material, made in the form of inlet 15 and outlet 16 holes. The fiber raw material is sent to screen 2 in the direction of arrow c. To supply fresh clean water, there is a pipe 17 connected to part 8 of the tubular distributor 6. The filtrate is discharged through the filtrate consisting of two sections 18 and 19 with outlets 20 and 21. Relatively clean drains from section 18 are pumped through the pipeline 22 using a pump 23 and is fed into the inlet pipe 24 re-circulated liquid. The conduit 24 is connected to the part 9 of the tubular distributor 6. The face plate 4 is provided with spiral vanes 2b having a cylindrical surface 26 for squeezing the raw material from the sieve. The device works as follows. Clean water is fed through pipe 17, and the gray raw material is fed through inlet 15 and is filled with sieve 2 to a level below the axis of the sieve when it is not rotating. The sieve 2 rotates at a relatively low speed. The raw material has a relatively high consistency (2-8)%. As the raw material is introduced into sieve 2, it comes into contact with the wash water which absorbs the ink particles in suspension, and passes through the grid 5 dl. removing this slurry through the outlet 21. The drains in section 18 are relatively clean and are recycled by a pump 23. As the gray feed moves into. sieve 2, it becomes gradually cleaner. The cleaned raw material is discharged through the outlet 16 with the help of blades 25. The gray raw material will reach a steady state with a continuous supply of clean water to the system, while the raw raw material and waste water will be continuously removed. Pump 23. runs continuously. When the screen 2 is rotated, the fibers in the raw material near the inner mesh 5 are moved due to friction forces between the mesh and the raw material in the direction of arrow B (Fig. 2). The raw material follows the movement of the grid 5 until the force of gravity causes it to run off the grid in the direction of arrow C. The feed is tilted without mixing in a sieve 2 around the perforated wash liquid dispenser 6. The fluid in which the ink is contained is transferred to the periphery through the grid 5. In FIG. 4 shows that the filtrate drainage means is semicircular and has an outlet opening 27. The filtering screening screen is made in the form of an endless filtering belt 28 with guide rollers 29–32. The sorting screen is rotated around the axis 34 by means of the roll 30, rotated from the shaft 35.. When the device is operating, the raw material filling the lower part of the sorting section 33 below the axle 34 is tilted. Inside the tilting material there is a tubular perforated distributor 36 of the washing liquid. The sorting section 33 has face plates 37 and 8.
