Definitions

  • the invention relates to a device for Conditioning bulk goods, such as chips or Chips, especially of a vegetable nature, such as wood chips for the production of fibers or Pulp for paper or board production or Fibreboard production according to the generic term of claim 1.
  • the conditioned bulk material is with the help of a Ragagagagates by one or more in Openings provided in the silo floor via screw conveyor carried out and the pulp mill fed.
  • a Ragagagagates by one or more in Openings provided in the silo floor via screw conveyor carried out and the pulp mill fed.
  • the object of the invention is a Facility with the characteristics of the generic term of claim 1 to the extent that largely simple with simple means Conditioning of the bulk material is achieved.
  • the invention shown in the drawing Facility 1 is for conditioning of bulk goods such as chips, fibers and the like provided and can preferably be used for processing of wood chips are used for the production of pulp for the paper or carton production or of fibers for fiberboard production can be used.
  • the Device 1 has a silo 2, the inside of the floor 3 has a clearing unit 4 which e.g. as a rotor with radially striving flexible Trailed arms or designed as a rotating floor can be.
  • a discharge screw conveyor 5 is arranged in the bottom 3 .
  • the discharge screw conveyor 5 can expediently be so long that it over the entire diameter of the silo 2 extends.
  • the discharge screw conveyor 5 has one located under the opening of the silo bottom 3 Trough 6 in which a screw conveyor 7 um an axis 8 is rotatably mounted.
  • Fig. 1 shows that the axis 8 to the vertical central axis 9 is not at right angles and runs in such a way that the discharge screw conveyor 5 rises in the conveying direction (arrow).
  • the rise angle can be about 3 to 15 ° C, preferably be about 5 °.
  • slant downwards inclined guide surfaces 10 for the from above in have the wood chips to be introduced into the Silo2 and as helix 11, wedge 12, funnel 13 and Cross bar 14 and be designed as a truncated cone can.
  • the conical internals 11 to 13 serve the uniform damping of the wood chips and simultaneous relief to avoid swelling of the wood chips Bridges of the bulk material in the silo 2 form. This ensures that the Bulk material achieved.
  • steam nozzles 15th provided at various points in the silo 2 are arranged so that a largely even steam introduction is achieved.
  • the present exemplary embodiment is the steam nozzle 15 both on the side walls of the silo 2 at different levels and distances as well on the crosspiece 14 and in particular also on or under the silo floor 3 and at the trough 6 of the Discharge screw conveyor 5 is provided.
  • the Steam nozzles 15 are arranged so that they are largely shielded from the bulk material, to avoid clogging of the nozzles.
  • a preferred arrangement of the steam nozzles 15 is provided on silo 2 in the area of rooms 16, which are located under the internals 11 to 14 or from their oblique guide surfaces 10 are limited. Especially the lower steam nozzles 15 are conical by sieve-shaped plates Openings (Fig. 5) protected.
  • FIG. 5 shows that the steam nozzles 15 conical outflow holes 17 can have, which in the direction taper the vapor flow (arrow). It can be advantageous to use the steam nozzle 15 in this way train that they are multiple or a variety of outflow holes 17, which is appropriate be provided in a sieve-shaped plate 18 can. Through the conical outflow holes 17 the steam nozzles become blocked by the Bulk goods avoided because of the smaller opening cross-section the conical or funnel-shaped Outflow holes 17 facing the wood chips is so that these are not in the outflow holes 17 can fix.
  • the steam nozzles 15 it is useful to use the steam nozzles 15 to be provided with an inspection opening 19, so that the interior 20 of the steam nozzle 15th is accessible from the outside if necessary.
  • the inspection opening 19 is with a removable cover or flange 21 closed on the steam nozzle 15 pivoted on an axis 22 is.
  • the front end of the steam nozzle 15 is a pipe 23 connected through which the hot Steam supplied for the conditioning of the bulk material can be.
  • Through the inspection opening 19 it is possible to use the interior 20 as well
  • To clean outflow holes 17 from the inside, to e.g. carried by the steam supplied or remove any impurities. 5 shows the cleaning opening 19 perpendicular to the longitudinal axis 24 of the steam nozzle 15 formed and arranged close behind the sieve plate 18, so that this sieve plate is easily accessible is and can be cleaned easily.
  • the wood chips are additionally conditioned in an impregnation station 25 after they have been discharged from the silo 2.
  • the bulk material is fed to the impregnation station via the discharge screw conveyor 5, which rises obliquely upwards in order to press steam out of the wood chips by compression.
  • the impregnation station 25 contains an impregnation liquid 26 which is located in an impregnation screw conveyor 27 which inclines obliquely in the conveying direction (arrow) and a preferably vertical cross conveyor 28 which is also designed as a screw conveyor.
  • the discharge screw conveyor 5 and the impregnation screw conveyor 27 are arranged with different pitch angles, the slope of the impregnation screw conveyor 27 advantageously being greater than the slope of the discharge screw conveyor 5.
  • the impregnation screw conveyor 27 can be arranged at an angle of approximately 5 to 60 °, preferably approximately 25 ° be, as is indicated in the present embodiment.
  • two or more discharge screw conveyors 5 When using two or more discharge screw conveyors 5 are also useful two or more impregnating screw conveyors 27 and two or more cross conveyors 28 provided so that overall a uniform and high quality conditioning of the Wood chips can be achieved. By using it of two or more discharge screw conveyors 5 will also be an equalization the dwell time of the wood chips is reached and it steam losses are avoided. You can also independently of each other several fiberizing mills be loaded, which makes considerable Costs can be saved because then not for each fiberizing mill has a separate silo have to be.
  • the internals 11 to 14 form a bridge of the bulk material avoided because the Downward movement of the bulk material on the silo wall is braked and nascent Vaults due to the faster downward movement collapse immediately in the middle of the silo.
  • the internals 11 to 14 can on the silo wall be arranged asymmetrically.
  • the one through the Steam nozzles 15 flowing into the silo 2 can become conical or wedge-shaped Distribute fittings 11 to 13 evenly and in a ring emerge, creating an optimal steam treatment the wood chips are obtained. Since none Bridges can form in the bulk material no channels in the property. The steam the bulk material can slowly move from bottom to top penetrate and is from the wood chips largely absorbed, so that practically none Loss of steam occurs and high efficiency steam treatment is achieved.
  • the woodchips swell to absorb moisture increasing their volume up, being in rooms 16 below the fixtures 11 to 14 can occur, so that the volume increase no blocking caused.
  • the even steam distribution in silo 2 is also supported by the fact that the steam nozzles 15 arranged at different locations of the silo 2 are, especially on the snail troughs 6 and on the silo floor 3 under the relief fittings 11 to 14.
  • the Schnitzel arrive due to the funnel-shaped Extension into the interior 20 of the steam nozzle 15 so that the outflow holes 17 remain free and do not clog.
  • the small schnitzel and any Impurities in the steam can pass through the inspection opening 19 easily from inside 20 to be removed.
