    (Fig. 1) / 16
    The invention relates to a device for producing pellets, with a machine frame, a hollow outer cylinder mounted therein with a first axis of rotation and an inner cylinder arranged in the outer cylinder with a second axis of rotation, a wedge-shaped gap being formed between an inner surface of the outer cylinder and an outer surface of the inner cylinder is, wherein the outer cylinder and / or the inner cylinder has substantially radially aligned holes for pressing material, and wherein a swivel arm is arranged on both sides next to the inner cylinder, on which the inner cylinder is rotatably mounted.
    Pressing crushed material into pellet form, which is also known as pelleting, offers numerous advantages, such as, for example, an increased bulk density, a standardized material size and the avoidance of segregation of different starting materials. In the processing of fuel, feed or bedding, pellets made from shredded biomass, e.g. Wood pellets, straw pellets or residual value pellets, which have gained in importance in the past decades and now occupy an important place.
    A device for forming strands from a combustible material mixture is known from AT 122 169 B. In the device described therein, the fuel mixture is introduced into a wedge-shaped gap between a rotating, hollow outer cylinder and a rotating inner cylinder arranged therein. The outer cylinder is set in rotation by a shaft and the inner cylinder, which is rotatably mounted between two arms and hangs down from the two arms which are rotatably mounted on the shaft, presses the fuel mixture through radial holes in the outer cylinder in the form of a strand.
    Furthermore, AT 346 705 B describes a device for producing compacts from bulk material. In this device, a wedge-shaped gap is formed between a press ring and a hollow press roller arranged therein / 16, into which the bulk material is introduced. The press roll is set in rotation, whereby the bulk material is pressed through the radial holes of the press ring and the press roll into compacts.
    Since the material to be pressed, in particular comminuted biomass, can have a very different quality, in particular as regards material properties and size of the comminuted material, it is disadvantageous if the device for pressing pellets cannot be adapted to different properties.
    The invention is therefore based on the object of providing a device of the type mentioned at the outset which can be used more flexibly than the devices known from the prior art.
    This object is achieved according to the invention with a device which has the features of claim 1.
    Preferred and advantageous embodiments of the invention are the subject of the dependent claims.
    According to the invention, it is provided that each swivel arm is movably mounted on the machine frame in the region of its two ends. As a result, the position of the axes of rotation of the outer and inner cylinders relative to one another and thus also the size of the wedge-shaped gap between the outer cylinder and the inner cylinder can be changed and the device can be easily and effectively adapted to differently sized, comminuted materials, in particular biomass.
    It is particularly preferred in the invention if a connecting element is arranged between the first end of each swivel arm and the machine frame, which is pivotally connected to the first end of the swivel arm via a first bearing 16 and pivotably connected to the machine frame via a second bearing.
    In a preferred development of this embodiment, the distance that the two bearings have from one another can be adjusted manually or automatically, for example by the connecting element having a threaded rod. The distance between the axes of rotation of the outer and inner cylinders and thus the gap width can thus be reduced or enlarged.
    As an alternative or in addition to this setting option, an embodiment is particularly preferred in the context of the invention in which each swivel arm is mounted on the machine frame at the second end by means of an eccentric shaft. The distance between the axes of rotation of the outer and inner cylinders and thus the gap width can also be reduced or enlarged.
    In a preferred development of this embodiment, the eccentric shaft has at least one first section with a first axis of rotation and at least two further sections with a second axis of rotation. The second axis of rotation is parallel to the first axis of rotation, i.e. is at a distance from this, whereby the other sections are eccentric to the first section. The eccentric shaft is rotatably supported with the first section in the machine frame and with the further sections in a second end of each swivel arm. The gap width can thus be adjusted by turning the eccentric shaft.
    In this embodiment it can further be provided that the eccentric shaft can be rotated via a drive. An electric motor, in particular a three-phase motor, is preferably used here, a gear being preferably arranged between the motor and the eccentric shaft. In the context of the invention, however, the drive can also be carried out manually via a lever or a crank.
    / 16
    The wedge-shaped gap between the outer cylinder and the inner cylinder has a gap width which can be changed, in particular enlarged or reduced, by changing the distance between the bearings of the connecting element and / or by rotating the eccentric shaft. Means, in particular sensors, can be arranged on the connecting element and / or on the eccentric shaft in order to be able to detect and output the distance between the bearings and / or the angle of rotation of the eccentric shaft. In a particularly advantageous embodiment, it is provided that both the outer cylinder and the inner cylinder are hollow and have essentially radially aligned holes. The inner cylinder is preferably driven by a drive via a gear and the material, in particular the shredded biomass, is introduced into the wedge-shaped tapering gap and pressed through the holes into an interior of the inner cylinder and out of the outer cylinder. This compresses the material and turns it into pellets.
    Further details, features and advantages of the invention will become apparent from the following description with reference to the attached drawings, in which a preferred and non-limiting embodiment is shown. It shows:
    1 is an isometric view of a device according to the invention,
    2 shows a front view of a device according to the invention,
    3 shows a section along the line A-A in FIG. 2,
    Fig. 4 is a section along the line B-B in Fig. 2 and
    Fig. 5 shows a section through the device normal to the
    Section plane of FIG. 3.

    1 shows an apparatus according to the invention for producing pellets, in particular from comminuted biomass, in an isometric view.
    A hollow outer cylinder 2 is rotatably mounted in a machine frame 1 and a hollow inner cylinder 3 is arranged in the hollow outer cylinder 2. A wedge-shaped gap 4 is formed between an inner surface of the outer cylinder 2 and an outer surface of the inner cylinder 3 (FIG. 5).
    Swivel arms 5 are movably mounted on the machine frame 1 on both sides of the inner cylinder 3. The inner cylinder 3 is rotatably supported approximately in the central region of the swivel arms 5.
    Each swivel arm 5 has two ends 6, 7. The first end 6 of the swivel arms 5 is movably connected to the machine frame 1 via a connecting element 8. The connecting element 8 is pivotally connected to the first end 6 of the swivel arm 5 via a bearing 9 and pivotably connected to the machine frame 1 via a further bearing 10.
    The second end 7 of the swivel arm 5 is rotatably mounted on the machine frame 1 via an eccentric shaft 13.
    In the illustrated embodiment, the connecting element 8 has a threaded rod 11 with two nuts, between which a bearing pin of the other bearing 10 is fixed. By adjusting the nuts 12, the distance between the two bearings 9, 10 and thus the size of the gap 4 can be increased or decreased.
    As shown in FIG. 4, the eccentric shaft 13 has a first section 23 with a first axis of rotation 22, which is rotatably mounted at two points 24 in the machine frame 1, for example in plain bearing bushes. Two further sections 25 with a common second axis of rotation 26 are rotatably mounted in the / 16 second ends 7 of the swivel arms 5, for example also in plain bearing bushes.
    The second axis of rotation 26 lies parallel to the first axis of rotation 22, as a result of which the further sections 25 are eccentric with respect to the first section 23.
    By rotating the eccentric shaft 13 with the help of a
    Drive 27, for example a three-phase motor, the second ends 7 of the swivel arms 5 are raised or lowered and simultaneously moved laterally. Through the connecting elements 8 and the thus formed, each having two degrees of freedom connections between the swivel arms 5 and the machine frame 1, the swivel arms 5 are able to carry out the lateral displacements associated with the rotation of the eccentric shaft 13.
    The connecting elements 8 can be used, for example, to preset or roughly adjust the gap width and, by means of the eccentric shaft 13, to continuously adjust or fine-tune the gap width.
    The drive 27 is connected via a transmission gear, not shown in detail, for example a planetary gear, to the eccentric shaft 13 and on the eccentric shaft 13 or in the drive 27, a sensor, in particular a rotary encoder, is arranged, which measures the rotation of the eccentric shaft 13, whereby the Width of the gap 4 can be determined.
    The outer cylinder has a first axis of rotation 14 and is mounted on both sides in the machine frame 1 via two cylindrical roller bearings 17.
    The inner cylinder 3 has a second axis of rotation 15 parallel to the first axis of rotation 14 and is rotatably supported in the swivel arms 5 via a spherical roller bearing 18.
    / 16
    The wedge-shaped gap 4 adjustable as described above has a maximum width at the top in FIG. 5 and a minimum width at the bottom.
    A clutch 19 connects the inner cylinder 3 to a transmission 20 which is not shown in detail in FIG. 3 and which can be, for example, a planetary transmission. The transmission 20 is connected via a further clutch 21 to a drive shaft, not shown, e.g. a cardan shaft, which is driven by a main drive, also not shown, whereby the inner cylinder 3 is set in rotation. The outer cylinder 2 rotates in the same direction as the inner cylinder due to the frictional forces that arise between the cylinders 2, 3 and the material compressed between them.
    In an alternative embodiment, not shown, the outer cylinder 2 is driven and set in rotation with a main drive, the rotation of the inner cylinder 3 being effected due to the frictional forces between the cylinders 2, 3 and the material. Another alternative embodiment provides that both the inner cylinder 3 and the outer cylinder 2 are driven.
    The material is introduced in the upper region of the wedge-shaped gap 4, through a filler opening 28 between the cylinders 2, 3 and is moved by the rotation thereof to the lower region of the gap 4 in the region of the minimum width.
    Both the outer cylinder 2 and the inner cylinder 3 have essentially radially aligned holes 16 through which the material, in particular comminuted biomass, is pressed in the region of the minimum width of the gap 4 when the inner cylinder 3 and outer cylinder 2 are rotating and is formed into pellets.
    / 16
    The pellets formed by the outer cylinder 2 fall out of the device at the bottom, for example directly into one
    Collection container or on a conveyor system. The pellets formed by the inner cylinder 2 collect in the interior of the inner cylinder 2 and, since the device and the inner cylinder 2 are open to one side, can fall out or be removed from the side of the device.
