Definitions
- the aim of the present invention is to carry out a technically and economically advantageous on-line pre-resolution in the pre-shortening of fiber-containing plant stalks or stems for the purpose of fiber extraction, before an abbreviation cut is made and the resulting fractions are subsequently separated from one another.
- the stalks of the fiber plants are either harvested in whole stalks or at harvest in sections from 500 to 600 or in step mowers to mostly 600 to 1200 mm, e.g. T. more, cut to length by simple cutting processes.
- the stalk material is shortened to sections of between 2 and 150 mm by simple cutting before the so-called deforestation. There are no pre-resolutions.
- a pre-dissolution of the stalks can bring considerable technical and economic advantages both during harvesting and during fiber extraction.
- a moderate pre-dissolution of the grown stalk structures means that numerous
- the mechanical effect of the pre-dissolution in the course of the harvesting process also means that a large part of the leaf material which is unsuitable for further use is crushed and falls off during the harvest. You get a purer crop. The unsuitable material for further use remains as natural fertilizer in the field.
- Another object of the invention is to facilitate the separation of wooden parts or cockroaches from the main product, the fibers, and to make them more complete. It has been shown that shives / wooden parts already detached from the fibers become increasingly caught again with the fibers, the more fine fibers and shives / wooden parts are dissolved, unraveled, crushed in the course of further process steps. It is therefore also an object of the invention to prospect the largest possible proportion of the shives / wood parts from the fibers, as long as they are still coarse and large and can be more easily viewed and separated from the fibers. As a result, the expense of fiber cleaning as the last stage of fiber extraction can be significantly reduced.
- the degree of pre-dissolution or pre-deforestation that is achieved with the solution according to the invention is even sufficient, so that further disassembly or fiberization can be omitted. Then costs are saved to a particularly high degree.
- the bulk material, which was pre-shortened to intermediate length during the harvest, is thus shortened again in a further cutting step in the plant. Then the bulk material is in a
- the mill is deforested or defibrated by impact, friction or shear in order to obtain fibers. According to the state of the art, all of the pre-shredded material is fed into the mill. This means that the mill is also unproductively burdened with wood-shaped, leaf or leaf-shaped components and accordingly a lot of energy is senselessly used.
- the object of the present invention is achieved in that machines known per se are modified and supplemented both for the crop cut and the end shortening in such a way that, prior to the cut short, the stalk or stem material of a striking and / or subject to kinking action.
- the intensity is limited to avoid loss of usable material in the field.
- pre-dissolution / shortening in the factory on the other hand, the effect is fully exploited to cause the brittle, wood-like material of the straw to splinter and detach, while the flexible fibers partially or strongly detach from the rigid wooden part due to the resulting shear stresses.
- the dry leaves and leaves still contained in the feed material also splinters under the influence and mostly break down into granules and dust.
- the cut-off is then carried out by a subsequent knife, which likewise represents an impact-like intervention in the material to be cut. This hard intervention leads to the cracks in the wooden part and between the wooden part and fibers or
- the brittle, wood-like material is severely shredded in the actual deforestation plant.
- Technical effort and costs can be significantly reduced if it is possible to introduce as little of the wood into the actual de-woodworking plant as possible, so that the share of shredded shives / wood in the fibers leaving the de-wooding plant is as low as possible .
- Figure 1 illustrates the device based on the preferred embodiment.
- the straw or stem material (l) is fed to a cutting rotor (3) at a constant speed via a feed device (2).
- the cutting rotor (3) is equipped with at least one knife (4) and at least one striking and kinking tool (5).
- the striking and kinking tool (5) has a shorter radius than the cutting knife (4) so that it can slide past the kinked material after the impact without causing the machine to lock.
- the striking and kinking tool should also be able to be arranged in a flexible manner in order to be able to dodge to the rear when the material layer is high.
- the striking tool should also be able to be designed in segments in order to allow adaptation to different layer thicknesses.
- bast peels off the wood in whole or in part or only loosens it.
- the blow and kinking of the preferably blunt tool is then followed by a cut through the subsequent knife (4).
- the cut also represents a hard mechanical intervention that expands existing cracks and continues existing peeling.
- the cut material is pushed through the knife at high speed over a rough friction surface ( ⁇ ) for discharge from the machine housing.
- the friction on the grater bar ( ⁇ ) leads to a further detachment of wood-containing constituents from the fibers and also to a further grinding of fragile sheet material into fines.
- the increasingly disassembled material then falls out onto a conveyor (9) which discharges it from the machine for subsequent viewing of the wooden parts / shives.
- Figure 2 shows a preferred combination of the device for pre-dissolving and shortening the stalk material with an equally novel viewing system, which is particularly suitable for the present purpose, the task of which is to separate fibers from detached wooden parts / cockroaches. Protection is also applied for the viewing system.
- Conveyor (9) passes the mixture of loosened fibers, fiber with wood / shives still attached and already loosened wood to the needle conveyor (IO). This consists of a large number of strips (10.1) in which needles (10.2) pointing upwards are fastened.
- IO needle conveyor
- Needle strips are connected by narrow belts to the needle strip conveyor belt (IO). Open spaces remain between the needle bars.
- the fibers and fibers with still adhering wooden parts have a tangled, felting consistency and are held and taken away by the needles (10.2).
- the dissolved wood or the cockroaches on the other hand, have a granulate-like structure and are very free-flowing. They cannot be held by the needles in the needle bars and fall through the bars onto a collecting tray (11) on which they slide to a collecting screw (12) and are discharged laterally from the needle bar conveyor belt system (IO).
- the preferably me- The metallic support and support structure of the needle bar conveyor system (IO) as well as the collecting tray (11) are equipped with one or more common or separate vibration exciters / vibrators in order to set the needle bar system (IO) in a permanent vibration, with the aim of loose Shake off wood / shives as intensively as possible from the fibers or the fiber-wood composite material. Likewise, the failed wood / shives should be shaken from the collecting tray (11) to the collecting screw (12).
- the fiber material largely cleaned of detached wood / shives, and fiber-wood / shank composites are thrown off at the highest point of the needle bar conveyor system by a high-speed rotating spiked roller (13) and pulled apart.
- the spiked roller (13) hurls the pre-dissolved material into a collecting shaft of the pneumatic conveyor system (15) in order to feed it to the main deforestation machine, which is not the subject of the present application and is therefore not shown.
- the radial fan (15) the material is subjected to a further impact by the rotor blades, which leads to a further detachment of wooden parts / shaving fibers.
- This loosened wood (shaving material) can then be separated from a vibrating trough with a screen plate as the floor before the main material flow is fed into the actual deforestation or fiber extraction plant.
- screening and classifying systems can be used and combined in many ways.
