Definitions
- the invention relates to a device for producing
- Such a device is in particular from WO
- pellets made from shredded biomass e.g. Wood pellets, straw pellets or residual pellets, in importance in recent decades
- Biomass which has a very different nature and can be particularly heavily contaminated with dust particles, there is the problem of these dust particles being deposited in the device, which leads to increased energy consumption and / or wear and tear or maintenance. This is particularly the case with lignin-containing materials, since the lignin in the
- Pelletizing device temperatures can lead to sticking.
- the invention is therefore based on the object
- At least one line for extracting air connects to the space between the inner cylinder and the outer cylinder, through which dust particles and also larger suspended matter, which are not pressed through the holes and can be deposited at other points within the device, are immediately extracted. These extracted solids are preferably returned to the material to be pelletized, so that no material is lost.
- pelletizing material is received before it is pressed through the holes, however, it is according to the invention
- the space has an interior and at least one exterior, and that the holes for pressing the material to be pelletized are in the area of the interior.
- the interior corresponds to the press nip.
- this aperture also contains the feed opening for the material to be pelletized, the line leading to the
- Extracting air is connected to the outside.
- the feed opening could also be at another
- the interior is delimited on both sides by panels, that exterior spaces are located outside the panels, and that the line for extracting air is connected to at least one of the two exterior spaces.
- the line for extracting air is connected to the outside space which is on the side of the screen in which the feed opening for the
- the line for extracting air may be connected to the outside space, which is on that of the feed opening for the material to be pelletized
- Air flow or several air flows can be generated in a targeted manner, which depending on the respective spatial conditions create ideal conditions for the extraction of floating material.
- Biomass which can have a very different nature, particularly with regard to material properties and size of the shredded material, it is disadvantageous if the Device for pressing pellets not different
- the device can therefore be constructed, for example, as described in WO 2018/104457 A. That is, the size of the wedge-shaped press nip between
- Outer cylinder and inner cylinder is changeable to the
- At least one screen is used in the present invention to separate the interior from the exterior
- the edge portion of the diaphragm overlapping the shoulder and a narrow gap in between it is possible to move the inner cylinder and / or the outer cylinder with respect to the diaphragm, while the interior remains delimited from the exterior .
- the width of the narrow gap only has to be adjusted once to the desired conditions and does not change if the wedge-shaped press gap between the outer cylinder and inner cylinder is changed.
- a line for extracting air can only be directed to one outside space or to both outside spaces
- the line for extracting air is connected to a conveying channel for the material to be pelletized and that the conveying channel is connected to the feed opening. This allows material to be sucked off while it is still in the
- Delivery channel is floating. Likewise, through this
- Embodiment also floating material can be sucked out of the space between the inner cylinder and the outer cylinder, in particular from the interior, in which the delivery channel opens.
- the room can have at least one opening for the supply of fresh air.
- fresh air does not mean that it must be fresh ambient air, but this fresh air can also be air from a circuit within a system into which the
- One or more of these openings can be arranged at any desired or suitable locations in order to bring about a targeted air flow which removes all floating particles from the device, if possible, so that these do not become deposited and can impair the function of the device.
- the opening for the supply of fresh air lies on the side of the room which lies opposite the supply opening, as a result of which an air flow running essentially through the entire room is made possible.
- FIG. 1 shows a side view of a device according to the invention
- FIG. 2 shows a section along the sectional plane II-II in FIG. 1,
- Fig. 3 is an oblique view of the device according to the invention cut along the section plane II-II, and
- Fig. 4 shows the drive end of a screw conveyor in a sectional view.
- the drawings show a device 1 according to the invention for producing pellets, the pellets consisting in particular of comminuted biomass.
- a hollow outer cylinder 2 is rotatably mounted about an axis of rotation 33 and a hollow inner cylinder 3 is arranged in the hollow outer cylinder 2.
- the inner cylinder 3 is rotatably mounted about a second axis of rotation 34 parallel to the first axis of rotation 33.
- a wedge-shaped press nip 6 is formed.
- the press nip 6 is largest in an upper region in the drawings and in the installed position of the device 1 and in a lower region
- the device 1 according to the invention as far as the setting of the wedge-shaped press nip 6 between the inner surface 4 of the outer cylinder 2 and the outer surface 5 of the inner cylinder 3 is concerned, can in principle be designed as described in WO 2018/104457 A.
- Outer cylinder 2 and the inner cylinder 3 are driven. If only one of the two cylinders 2, 3 is driven, then the other cylinder 3, 2 is also rotated by the frictional forces which arise from material to be pelletized, which is fed into the press nip 6 and compressed in the lower region of the press nip 6.
- the material in particular crushed biomass, is in the upper region of the wedge-shaped press nip 6 by means of a
- Delivery channel 10 introduced through a feed opening 7 between the cylinders 2, 3, by the rotation thereof to the lower
- Inner cylinder 2 are open to the side, from the side
- a space 11 is formed between the outer cylinder 2 and the inner cylinder 3, which is additionally shown only schematically
- the space 11 is divided by panels 14, 15 into an interior 16 and two exterior spaces 17, 18.
- the interior 16 is located between the outer cylinder 2 and the inner cylinder 3 and between the two panels 14 and 15. In this embodiment, the interior 16 corresponds to the press nip 6. Outside the panels 14, 15, the two outer spaces 17, 18 are located.
- Inner cylinder 3 and the side walls 12, 13 formed.
- the two outer spaces 17, 18 can of course also be delimited by other sections of the device 1.
- the panels 14, 15 each have a radially inner edge portion 22 and a radially outer edge portion 23 which is parallel to the shoulders 19, 20 and these
- a narrow gap 24, 25 is formed between the edge sections 22, 23 and the shoulders 19, 20, which gap is preferably so small that the material to be pelletized cannot essentially pass through.
- the width of the narrow gaps 24, 25 is so large that there is friction between the panels 14, 15 and
- At least one line 27, 28, 29 is provided for this, but it can also be a plurality of lines 27, 28, 29, which are connected to different areas or rooms 16, 17, 18 within the device 1.
- conveying channel 10 is formed by a screw conveyor 35 shown in FIG. 4, on the drive end 36 of which the line 29
- the line 29 can also be connected to another location of the delivery channel 10.
- a further improvement in the extraction of air according to the invention can be achieved in that an opening 31, 32 is provided at one or more points of the device 1 for the supply of fresh air. On the one hand, this ensures a sufficiently high volume flow, which
- device 1 which is essentially of a tight design, would otherwise not have been provided.
- the air flow within the device 1, in particular the space 11, can be arranged through a targeted arrangement of one or more openings 31, 32 for the supply of fresh air can be controlled and directed to critical points.
- Such openings 31, 32 can be provided, for example, in the area of the two outer spaces 17, 18, both in their upper and lower area.
