Definitions

  • the invention relates to a screw mill for crushing and pressing regrind, consisting of two motor-driven screw conveyors, which are arranged side by side in a housing and rotatably mounted, with a feed opening in the top of the housing on the inlet side and a shaping and pressing head on the front side of the housing.
  • Screw mills with which regrind is crushed and pressed, are known in various designs. A rough distinction is made between the number of screw conveyors used, i.e. one, two or more screw conveyors. Another distinction is whether additional media in the form of nozzles and orifices are used to achieve additional grinding and pressing.
  • the housing is composed of housing elements in which two screw conveyors composed of screw elements are mounted. Throttle disks are arranged between the housing elements, which block the passage of the screw conveyors except for a relatively small throttle gap.
  • the drive of the Screw conveyors are carried out via a gearbox and the shafts of the screw conveyors extend through the gearbox and are supported on an axial bearing which is attached to the housing by means of tie rods.
  • this known screw press is that it can be used for processing very different materials without major modifications.
  • the squeezed liquid is suctioned off and the solid can be dried and briquetted through a molding head.
  • the use of throttling disks means that the regrind, in particular organic material, is disrupted by the movement on the throttle disk, i.e. that the cell walls are opened, but there is considerable wear on the throttle disks, which can be considerable even when using hard metal as a coating.
  • Another disadvantage is that the use of throttling disks or other throttling elements causes a reduction in the processing capacity.
  • the present invention relates to a screw mill in which two adjacent screw conveyors are used, but no throttling disks or other throttling members are used. It is the object of the invention to achieve a substantial increase in the processing capacity of regrind, but at the same time to reduce the wear on the screw conveyors and in the housing and still ensure a complete unlocking of the cell walls.
  • the two screw conveyors are divided into two different sections, of which, in a first inlet-side section, the screw conveyors act as a co-operating, intermeshing one in a common working space Conveying screw pair and in a second, the forming and pressing head forming outlet-side section are designed as individual screw conveyors with separate work spaces.
  • This pressing effect is further increased if the screw conveyors have a larger diameter in the first section than in the second section.
  • the system shown in Fig. 1 has two screw mills 1, 2, which are driven by two electric motors 3, 4.
  • the electric motors 3, 4 drive the two screw mills 1, 2 via a reduction gear 5.
  • the reduction gear 5 can be designed in several stages and has two output shafts 6, 7, which rotate in the same direction or against each other. The direction of rotation of the output shafts 6, 7 is selected in accordance with the design of the screw mills 1, 2.
  • the drive shaft 8 of the reduction gear 5 is connected to the motor shafts 9, 10 by means of a shaft coupling (not shown).
  • the two output shafts 6, 7 of the reduction gear 5 are connected to the drive shafts 13 of the screw mills 1, 2 by means of shaft couplings 12, for example flange couplings.
  • Each of the screw mills 1, 2 has two drive shafts 13, each of which drives a screw conveyor 14, 15.
  • the two screw mills 1, 2 are constructed essentially the same, but the screw conveyors 14 in the screw mill 1 are composed of a larger number of screw conveyor sections 17 than the screw mill 2.
  • the screw conveyor sections 17 are provided with screw flights 18 which partially interlock.
  • the screw conveyors 14, 15 are mounted in a housing 19.
  • the Housing 19 can, as can be seen in the screw mill 1, be composed of several sections, the length of which can be one or more times the length of a screw conveyor section 17.
  • the housing has a cavity 48 for the passage of coolant or heating medium for temperature control of the material to be processed.
  • a bearing housing 20 is fastened to the housing of the two screw mills 1, 2, in which the bearing 21 of the screw conveyors 14, 15 is accommodated.
  • the bearing 21 is only shown schematically and, depending on the size of the screw mill, comprises bearings, mostly roller bearings, for absorbing the radial and axial forces that occur.
  • the screw conveyors 14, 15 of the two screw mills 1, 2 are divided into two sections, of which, in a first, inlet-side section, the screw conveyors 14, 15 are designed as a cooperating, intermeshing pair of screw conveyors lying in a common working space.
  • a second, outlet-side section adjoins the first inlet-side section, which forms a molding and pressing head with two outlets 23.
  • the screw mill 1 has five screw conveyor sections 17 in its first section, while the second section comprises three screw conveyor sections 17.
  • the first section comprises three screw conveyor sections 17 and the second section comprises two screw conveyor sections 17.
  • the screw conveyors of the second section are accommodated in separate work rooms and have a smaller diameter at their screw conveyor sections.
  • the transition from the first to the second section takes place by means of a conical screw conveyor section 25.
  • the configuration of the second section of the screw conveyors is described in detail with reference to FIGS. 3-6.
  • FIG. 2 shows a system with only one screw mill 1, which is driven by an electric motor 3 via a reduction gear 5.
  • the screw mill 1 of the embodiment shown in FIG. 1 is, however, shown in a side view, so that only the one screw conveyor 14 is visible.
  • the same reference numbers are therefore used, with no further detailed description being given.
  • a loading opening 26 can also be seen, which is surrounded by a funnel 27. Furthermore, it can be seen from FIG. 2 that an intermediate housing 28 is arranged between the reduction gear 5 and the screw mill 1, the bottom 29 and ceiling 30 of which can be seen.
  • the screw mill 1, the reduction gear 5 and the electric motor 3 are each supported on a base 31, 32, 33, the bases 31, 32, 33 being mounted on a foundation frame 34.
  • the foundation frame 34 which is essentially box-shaped, is supported by a number of profile supports 35, via which the foundation frame 34 is connected to the floor (not shown).
  • FIG. 3 shows the second section of a screw mill, which is designed as a molding and pressing head.
  • the conical screw conveyor section 25 adjoins the screw conveyors in the first section of the screw mill.
  • a cylindrical screw section 36 then follows, and an end section 37 at the end.
  • a housing section 38, 39, 40 is assigned to the conveyor screw sections 25, 36, 37.
  • a cylindrical molding tool 42 is fastened, by means of which the treated material emerging is shaped.
  • FIG. 3 shows a pull rod 43 which ends in the first section and on which the screw conveyor sections 17 of the first section are lined up and fastened.
  • the conical screw conveyor section 25 and the cylindrical screw conveyor section 36 are screwed onto the pull rod 43 with a screw 45 on the conical screw conveyor section 25.
  • the screw flights 18 are shown with lines for the sake of a better overview. In reality, however, the gears 18 are helical, radially projecting webs. 3 further shows that the separation of the two screw conveyors into separate work spaces in the housing section 38 begins with the conical screw conveyor section 25.
  • FIG. 4 shows a second embodiment of the second section of the screw conveyor.
  • the first section ends with the cylindrical screw conveyor sections 17, and the second section begins with the conical screw conveyor section 25 in the housing section 38.
  • the end section 37 with the housing section 40 then follows, without any between the screw conveyor section 25 and the end section 37 cylindrical screw section 36 would be inserted.
  • the slightly modified design of the second section compared to FIG. 3 allows the screw mill to be adapted to different materials to be processed.
  • the shaping tool 42 in the embodiment according to FIG. 4 is the same as in the embodiment according to FIG. 3.
  • the conical screw section 25 and the end section 37 are fastened in the same way as in FIG. 3.
  • FIG. 5 shows a further embodiment of the second section of the screw mill, in which only the conical screw conveyor section 25 and the cylindrical screw conveyor section 36 with their corresponding housing sections 38, 39 are used.
  • the end section 40 and the molding tool 42 are omitted here, so that the emerging, processed material exits in the form of a hollow cylinder, which is advantageous when processing certain materials.
  • FIG. 6 shows a further embodiment of the second section of the screw mill, which only has the conical screw section 25 with the housing section 38.
  • This embodiment of the second section can also be advantageous for the processing of certain materials.
  • the screw mill 1, 2 can be further adapted to the material to be processed, in which the housing 19 is designed such that the screw conveyors 14, 15 can be both heated and cooled.
  • the housing 19 or the housing sections are made in two parts and held together by screws, the bores 46 of which are shown in FIG. 1 in the screw mill 1.
  • the screw mill 2 can be designed in the same way.
  • the screw mill described is suitable for processing various materials, especially organic materials. It is characterized by a high processing capacity. If the material to be processed is briquetted, the processing capacity can be three times or more compared to a comparable screw press with throttling points. The processing capacity is particularly large in the production of granules, where in an embodiment according to FIGS. 5 and 6 a loose discharge takes place. There can Processing capacity ten times or more compared to a comparable screw press with throttling points.
  • a bore can be formed in the emerging material, which can serve as a steam collector and steam exhaust. It is essential that with all the mills described, the fibers are reliably broken down in the processing form of all organic materials. ie the cell wall is opened. When processing the material, heat is generated by the grinding friction in the first and second sections of the screw mill, the temperature being kept at a specific value by cooling or heating.
