Definitions
- the invention relates to a pelletizing device for loose material, in particular dry waste material, with a hollow cylindrical housing that has an axis and a radial resistance generating radial openings in the housing wall, with a pressing element rotating about an axis in the housing, which with a rotating around the housing axis rotating drive element is provided, and with radially arranged radially to the axis of the extrusion press rams, which penetrate into the openings in the housing wall during the rotation of the extrusion element, pressing the material outwards, and withdrawing from the openings.
- Such a pelletizing device is known for example from DE-B 1222895.
- the housing is formed by a trough having the openings and a cover covering the trough.
- the squeezing element has an axis of rotation parallel to the horizontal axis of the housing, and circles around the axis of the housing, so that the material fed into the tub is gradually pressed outwards by the ram through the housing openings.
- a pelletizing device improved according to the invention is now characterized in that the axes of the housing and the extrusion element run vertically, and the openings in the housing wall are arranged uniformly distributed in at least one horizontal radial plane.
- the material Due to the vertical arrangement of the housing axis and the drive element, the material is pressed horizontally on all sides into the openings distributed all around in the housing wall. This improves the distribution of the load on the individual parts of the device.
- the squeezing element can be a non-circular, in particular elliptical body, which is connected to a central drive shaft and which moves and presses in the ram, which can be displaced radially to the housing axis.
- a press ram is thus assigned to each opening of the housing.
- the axis of the extrusion element is rotatably mounted on the drive element parallel to the housing axis and the extrusion element is rotatably mounted around the housing axis.
- the drive element is a crank that rotates the extrusion element relative to the housing. In this way, a very high compression of the material can be achieved.
- the press rams engage in the manner of a circumferential toothing of an eccentric gear wheel in the openings of the housing and effect the circular guidance of the extrusion element.
- An additional gear can preferably be provided so that the press rams enter the openings of the housing with play and do not come into contact with the housing.
- An advantageous embodiment consists in the fact that an externally toothed wheel connected to the pressing element is rotatably mounted on the drive element and rolls in an internally toothed ring fixed to the housing.
- the ring is preferably designed as a roller chain fixed to the housing.
- Such a gearbox has a very high reduction ratio with a small space requirement, which is based on the difference in the number of teeth.
- the use of a roller chain as an internally toothed ring makes the gearbox cheaper, since no internal toothing has to be produced.
- the housing-fixed fixation can be achieved particularly easily by using a two-track chain, one track representing the internal toothing and the second track surrounding a chain toothed ring which is attached to the housing.
- the externally toothed gearwheel performs the same movement as the rotating extrusion element, so that the two parts can be directly connected.
- a feed channel for the material to be pelletized opens into the space between the housing and the extrusion element above the press ram.
- the feed channel can contain, for example, a driven screw conveyor.
- a pressing element arranged in a circle can be provided with stirring blades, with which the supplied material is better distributed over the individual openings of the housing, so that a more uniform pelleting takes place. Since the device pelletizes in particular loose, dry material, in a further embodiment the press rams and the openings can also be arranged in several radial planes.
- the press rams are preferably interchangeable and / or adjustable in length, the length setting changing the immersion depth in the openings, replaceable and / or length-adjustable nozzles are preferably used in the openings, their length setting changing the pressing resistance.
- the nozzles can in particular consist of a material which is inert with respect to the material to be pelletized. The materials can thus be selected and also changed according to the requirements, in particular being corrosion-resistant, abrasion-resistant, etc. Stainless steel is particularly suitable for the press rams and hard bronze for the nozzles.
- a pressing resistance is necessary for the pelleting, which of course must not be too high in order to avoid damage to the device.
- a preferred embodiment therefore provides that an element regulating the pressure resistance is provided in the outlet area of each nozzle. If the pressure resistance becomes too high, the control element yields, which increases the outlet cross section and reduces the pressure resistance again.
- the control element can protrude inwards in a particularly adjustable basic position, and is particularly elastically loaded. In order to facilitate the introduction of the material, in a further preferred embodiment the inlet area of the nozzle can extend up to the control element.
- FIG. 1 shows a partially sectioned, diagonal view of essential parts of a first embodiment of the pelletizing device according to the invention
- FIG. 2 shows an axial section through the embodiment according to FIG. 1
- 3 shows an end view of an outlet nozzle for the pellets
- Fig. 4 is an axial section through a second embodiment of an outlet nozzle
- Fig. 5 is a schematic horizontal section through a second embodiment.
- a relatively high compression of the waste material is required for pelletizing, in particular, dry waste material, for example cardboard or paper dust, wood chips, etc., into fuel.
- Pellets from cardboard or paper dust should have a density of at least 1.3 kg / dm 3 , in particular 1.5 kg / dm 3 , which can be achieved with nozzles with a diameter of approximately 2 cm with pressing forces of 150 to 200 kN.
- FIGS. 1 to 4 A first embodiment of a pelletizing device is shown in FIGS. 1 to 4.
- a hollow cylindrical, device-fixed housing 1 has a vertical axis 5, and is closed at the bottom by a base plate 2 and at the top by a cover plate 25 (FIG. 2).
- a drive element 4 has two bearing journals 3, which are mounted in the base plate 2 and the cover plate 25 centrally in the axis 5 of the housing 1.
- a drive (not shown) is assigned to the upper bearing journal 3, but instead the lower bearing journal 3 can pass through the base plate 2 and a drive can be provided there.
- the drive element 4 between the two journals 3 is cylindrical and has an axis 6 which runs parallel to the axis 5 of the housing 1 and the journals 3.
- On the drive element 4, a likewise hollow cylindrical extrusion element 7 is rotatably mounted.
- the press-out element 7 carries a lower ring of outwardly projecting press rams 9, which are adjustable in length in punch sleeves 8 fixed to the press-out element 7, an externally toothed wheel 22 at the upper end, and outwardly projecting wings 17.
- the externally toothed wheel 22 engages due to the eccentric arrangement of the pressing element 7 only over part of its circumference into a housing-fixed internal toothing 23, so that the pressing element 7 does not rotate when the drive shaft 4 rotates about the housing axis 5, but rotates on the drive shaft 4 about its axis 6 and encircles the housing axis 5, the externally toothed wheel 22 rolling in the inner toothing 23.
- the housing 1 has radial openings 10, into which nozzles 11 are inserted, at the level of the press ring. In the illustrated embodiment, the number of openings 10 is larger by one than the number of press rams 8, which gradually move into the rotation of the pressing element 7 Enter openings 10 and withdraw from them again.
- Material is introduced laterally into the space 21 between the housing 1 and the extrusion element 7 through a feed channel 19, in particular equipped with a screw conveyor, above the ram 8 and by the circular movement of the extrusion element, supported by the protruding wings 17 all around
- the press rams 9 each capture a small one
- FIGS. 2 and 3 show in detail a first embodiment of a nozzle 11 with a control element 12 which can be pivoted about an axis 13 and which is formed by a nozzle insert, the basic position of which can be adjusted by means of a handwheel 16.
- the handwheel 16 is rotatably mounted in an approximately U-shaped or bracket-shaped bracket 15, the side legs of which penetrate or grasp the nozzle 11 and are supported on the opposite side by springs 14.
- the nozzle insert which itself consists in particular of an elastic material, can be pivoted about the axis 13 in such a way that in the region of the axis 13 the passage cross section does not essentially change when the control element 12 dodges.
- the area of the nozzle insert lying inwards from the axis 13 is chamfered or rounded (FIG. 2).
- the lower bearing of the drive element 3 is covered by a sealing washer 18.
- the lower bearing 20 of the press-out element 7 is covered by a seal 27 surrounding the drive element 4 against penetrating material.
- a control element 31 is provided in the outlet area of the nozzle 11, which is formed by a sleeve made of plastic.
- an expandable ring 32 is provided, the inner diameter of which is smaller than the diameter of the sleeve.
- a suitable rubber-elastic plastic can have a Shore hardness of 70 to 80, for example.
- the ring 32 by one metallic ring 33 reinforced, which rests on the outside of the expandable ring 32 and on the
- Nozzle 11 or on the housing 1 is fixed.
- the externally toothed wheel 22 is preferably designed as a chain wheel, to which a track of a double roller chain is assigned as the internal toothing 23.
- the second track of the double roller chain encloses a second externally toothed sprocket 24, which is fixed to the housing 1 via a support ring 28.
- a seal 26 is also provided between the sprocket 24 and the wheel 22.
- the press rams 9 are guided radially displaceably in a ring 30 fixed to the housing, and are also gradually pushed into the opening 10 and pulled out again by the rotating pressing element 7, so that the same insertion and pressing process is given.
- the press rams 9 can be arranged on a flexible element in which the elliptical extrusion element 7 rolls. Furthermore, the press rams 9 could also be pushed in and out by means of a crankshaft-like drive.
