Definitions
- the present invention relates to a method and a device for obtaining a fiber material suitable as a raw material for insulation purposes or for producing nonwovens or as a filler or cushioning material, and uses of the fiber material.
- the known raw materials can be, for example, cotton, animal products or plastics.
- Obtaining a raw material from animal products requires partially ethically questionable factory farming because the animal products are made from duck and goose down or feathers.
- plastics e.g. Foams
- Foams as insulating or fillers
- these plastics have only a low level of breathability and, in some cases, give off harmful evaporation.
- Cotton fibers are used to produce insulating and filling materials or nonwovens. It is known that cotton harvesting and egrenier machines are used to harvest and obtain vegetable fibers from the fruits of cotton plants. With the help of these machines, already opened cotton capsules are cut off and taken up. The fibers are usually won nen that they are taken from the already opened fruit capsules. The fibers are separated from the seeds of the cotton plant using mechanical Egrenier processes and centrifugal methods.
- DE 183 923 discloses a machine for extracting the fibers stuck to cotton seed pods, in which the machine strikes the material to be processed with great force by striking elements.
- a lintering machine known from DE 23 37 227 AI is intended for the further processing of cotton seeds with linters adhering to them (short-staple cotton), for which seeds the long-staple cotton had previously been separated by an egreting machine.
- the Linter-Egrenier machine mentioned uses, inter alia, a drum which is lined on the inside with abrasion material.
- the object of the invention is to develop, in place of the known ways of obtaining cotton fibers, the easiest and most effective way of obtaining a vegetable fiber material that is gentle on the fibers.
- the solution according to the invention consists in a method according to patent claim 1, a device according to patent claim 18 and proposals for using the fiber material obtained by the method according to patent claims 34 to 40.
- the invention according to claim 1 is a method for obtaining a suitable as a raw material for insulation or for nonwoven manufacture or as a filler or upholstery fiber material from fruits of poplar, willow, aster family or similar plants, in its use closed fruits of poplars, willows, composites or similar plants in a treatment room using an air Current are dried and / or opened and moved in the treatment room in such a way that the fiber material contained in the fruit capsules is largely detached from the other fruit components.
- fruit is not to be understood here as the botanical-scientific term, but rather fruit capsules, seed capsules, possibly also pseudo fruits, which can be harvested as a unit from the plant (if possible in a largely or completely closed state), which when opened as part of the The method according to the invention release the fibers and seeds, the fibers being largely separated from the seeds by the method.
- the solution according to the invention makes it possible to substitute the known insulating materials or fillers in that a natural plant material native to Central Europe and many other regions of the world can be obtained with the same or improved quality characteristics.
- monocultures with the required use of pesticides and landscape use can be dispensed with, as well as long transport routes.
- the seed hair, flight appendages of the seeds, of different poplar or willow species (Salicaceae family) as well as daisies (Asteraceae family) and Epilobium species are suitable.
- the seeds do not necessarily have to be completely separated from the seed hair, since they can still be finally loosened and fail in subsequent processing processes in carding machines or carding machines.
- the fruits of the salicaceae can neither be harvested from the tree with existing machines, nor does the white fluff of the fruit (seed hair, flight attachments of the seeds) stick to the fruit capsules after opening the fruit capsules, because the flight attachments are already carried away by the light wind.
- the percussion elements of the machine according to DE 183 923 would cause the fibers to be contaminated / discolored by colored plant components and / or to cause the fibers to be contaminated by vegetable oil by squeezing the seeds. It is also important that the striking elements act mechanically on the plant fibers in an extreme manner, which results in a significant reduction in the quality of the fiber raw material obtained.
- a single The procedure is to open the fruit capsules, separate them from the remaining components of the supplied material and detach the appendages from the seeds. Because branches and leaves can also be filled into the container together with the fruit capsules, the plants to be picked do not have to be artificially defoliated.
- the crop is pretreated in such a way that it is stored for one to two days at high atmospheric humidity (the intrinsic moisture and possibly condensation moisture are generally sufficient) in order to initiate the process of detaching the seeds from the seed hair in a manner which is gentle on the fibers and without mechanical influences .
- the crop is pretreated in such a way that it is watered for several days in order to initiate the process of detaching the seeds from the seed hair in a manner which is gentle on the fibers and without mechanical influences.
- the crop is pretreated in such a way that it is deep-frozen before being poured into the device in order to promote the detachment process of the seeds from seed hair.
- the crop is pretreated in such a way that it is pretreated before being filled into the device by at least initial fermentation and / or milling (mechanical pressure exerted on the closed capsules).
- the crop is pretreated in such a way that it is shaken by vigorous shaking before being poured into the device.
- the air flow leads the fiber material to a separation chamber, the air flow weakened in the separation chamber and the fiber material is collected, for example in a net (safety net).
- the air flow carries the fiber material out of the treatment space of the container and directs the fiber material to the separation chamber.
- the air flow loses a large part of its eroding power in the separation chamber.
- the heavy particles entrained in the air stream such as seeds and smaller pieces of fruit capsules, can deposit on the bottom of the separation chamber.
- These can also be separated using screening techniques or other separation processes.
- the much lighter appendages are carried out through the outlet of the separation chamber with the much weaker air flow.
- the air flow carrying the flight tags then feeds the flight tags to the net, the mesh size of which roughly corresponds to that of a mosquito net. The air can escape while the flight tags are being caught.
- fruit-bearing branch material is brought into the treatment room.
- the branch material can be kinked from the coarse branches, stripped and / or chopped before filling into the container. Cutting fruit capsules while chopping is not a problem.
- the separation process can be accelerated by moving the container or having a movable inner insert (drum insert).
- a movement of the components which promotes the separation of the components can be achieved in that the container or a container insert is arranged horizontally and rotates about the longitudinal axis of the container.
- the separation of the seeds from the seed hair is promoted by the use of fillers in the rotating drum, which hit the seed hair associated with the seeds by falling.
- fillers with a non-hard or soft surface a white Test-protecting the fibers.
- light fillers with a hard surface can additionally be used in the rotating drum, depending on the type of plant. More preferably, cork granules can also be used in the rotating drum.
- cereal grains remains of corn cobs / inner pieces, acorns, chestnuts, wood chips, bark chips, chippings, broken split, crushed limestone (broken limestone), light stones such as expanded clay or tufa stones or similar fillers can also be used.
- the separation chamber extends much more (twice in one example) in the horizontal than in the vertical direction. This results in the advantage that the contaminated material no longer hinders the pure fiber material suspended above as the two fractions to be separated flow along separate paths from the point of exit from the connection channel leading to the separation chamber.
- the fiber material collected in the collecting net can optionally be further processed in order to at least partially produce insulating materials, filling materials, papers and body pads or supports and / or nonwovens from the fiber material.
- the fiber material is suitable for allergies to bird feather and animal hair.
- a cyclone separator is provided instead of the separation chamber with a collecting device, by means of which the light seed hair is separated from the heavier impurities. According to the current view, this version is not very gentle on the fibers.
- At least two of the previously mentioned method or device features can be combined with one another.
- Fig. 1 shows a schematic side view of an apparatus for performing a method for obtaining fiber material from fruit capsules of poplar, willow, daisy or similar plants.
- Fig. 2 shows an embodiment with an exhaust fan.
- Fig. 3 shows an embodiment with a drum arranged slightly inclined to the horizontal plane.
- Fig. 4 shows a non-rotating transition piece.
- Fig. 5 shows a relatively long separation chamber.
- Fig. 6 shows an output end face of a drum.
- Fig. 7 shows an output end face of another drum.
- Fig. 8 shows a cross section through a drum with driving ribs or teeth.
- FIG. 9 shows the driver tines of FIG. 8 in a top view.
- Fig. 10 shows in cross section a pipe with flow obstacles.
- a device 1 for Carrying out the method comprises a container 10 with a drum insert 11.
- An outlet 12 of the container 10 is connected to a separation chamber 13 so that the container 10 has a passage to the separation chamber 13.
- a connection channel 14 adjoins the outlet 12, which in the example runs in a straight line, but in other embodiments is helical.
- the container 10 can be filled with fine branches 16, so that an inhomogeneous material can be moved in a treatment room 17 of the container 10.
- the treatment room 17 is supplied with fine branches 16, the fruit capsules 19 on the spindles 18 of which have not yet been opened.
- the inhomogeneous material of the treatment room 17 is composed of fine branches 16, fruit capsules 19, leaves 20, buds, seed hair 21 and seeds 22.
- the drum insert 11 is arranged in the horizontal direction (that is to say with a horizontal axis of rotation 24) and can rotate in the direction of the arrow 23 about the axis of rotation 24 of the container 10. At least one shoulder, wing or driver 25 formed on the edge of the drum insert 11 lifts the inhomogeneous material with each rotation.
- Heated air can be supplied to the treatment room 17 in the flow direction 27 via an inlet connection 26.
- the inflow of air leads on the one hand to a drying process of the fruit capsules 19, which are thereby opened and release the seeds with the seed hair.
- the fruit capsules 19 are swirled together in connection with the movement of the drum insert 11 in the treatment room 17. This contributes to the loosening and / or loosening of the seed hair 21 from the seeds 22.
- the seed hair 21 is blown by the air flow in the flow direction 28 from the treatment room 17 into the separation chamber 13.
- parts of the other foreign bodies can also get into the separation chamber 13.
- the air flow is weakened when entering the separation chamber 13, so that only the seed hair 21 can be moved by the air flow in the separation chamber 13.
- the air flow is weakened because the flow cross section of the separation chamber 13 is larger than that of the connecting channel 14, as the drawing shows.
- the foreign bodies to be separated from the seed hair 21 by the process such as leaves 20 and fruit capsule components 19, fall downward in the separating chamber 13 in the direction of the arrow 29 and accumulate on a bottom 30 of the separating chamber 13 because the air flow no longer moves is strong enough.
- the seed hairs 21 are fed in the flow direction 31 via an outlet connection 32, a collecting net 33.
- the outlet port 32 is located in an elevated position with respect to the connecting channel 14, so that it is ensured that foreign bodies cannot get into the outlet port 32.
- the safety net 33 is fine-meshed, comparable to a mosquito net.
- the seed hair 21 can collect in the collecting net 33.
- the safety net 33 is detachably connected to the outlet connection 32 so that the collected seed hair 21 can be fed to further processing as fiber material for fillers or insulating materials.
- the container 10 and the separation chamber 13 are arranged, for example, to carry out the method.
- a container of a device is to be used which in one embodiment has a plurality of treatment rooms arranged one behind the other.
- the drying temperature in the drum insert 11 is kept so low that the capsules open only slowly.
- the appropriate temperature varies depending on the type of plant.
- the speed of rotation of the drum insert 11 is kept so high that the crop is often lifted with the capsules still closed and falls to the bottom of the drum insert. This already loosens or loosens the connection between the seeds and the seed hair.
- the already loosened semen hair 21 and the semen hair still connected to the semen with a loosened connection are led out of the drum insert by a correspondingly strong air flow before they are showered more frequently by the other crop and their fiber quality is thereby impaired.
- FIG. 2 shows a particularly fiber-friendly embodiment of the invention, according to which a blower as a suction blower 35 is located behind the collecting device, the collecting device being located in a closed space 34.
- the axis of rotation 24 'of the drum insert 11' is not in a completely horizontal position, but in a position inclined by a few degrees to the horizontal plane 37. This ensures that the undigested crop remains closer to the heating, while the light fiber material is already being moved in the direction of the connecting channel 14 '.
- the advantage here is that the impure material that is whirled up does not reach the connecting channel 14 ′ so strongly, as a result of which better pre-cleaning is achieved.
- the suction surface 36 'of the connecting duct 14' can thereby be increased and the blower output of the suction device can be increased. Another advantage arises from the fact that the released seed hairs are no longer exposed to temperatures as high as the crops which have not yet been broken down and are thus additionally protected with regard to the thermal effects. Furthermore, the heating energy is used more effectively.
- Fig. 4 shows details of another preferred embodiment of the device.
- a non-rotating transition piece 82 is attached between the container 10 and the connecting channel 14 ′′, the diameter of which is somewhat smaller than that of the drum insert 11 and much larger than that of the connecting channel 14 ′′. This ensures that, on the one hand, due to the larger diameter with a correspondingly lower flow rate, more light seed hair and less contaminated material get into the connecting channel 14 '', whereby better pre-cleaning and more effective suction of the seed hair is achieved, and on the other hand less swirled contaminated material into the connecting channel 14 '', which also results in better pre-cleaning.
- Fig. 5 shows a relatively long, horizontally arranged separation chamber 13 ', in which the path of the fibers, which are moved by flowing air, is separated early from the path of the other fruit constituents.
- FIG. 6 shows an end wall of the drum 11 on the outlet side, which has a central opening 70 with a surrounding imperforate edge 72 which prevents coarse particles from falling through.
- FIG. 7 shows an alternative form to FIG. 6, in which perforation holes 71 are provided instead of the central large opening. There is also a non-perforated outer area here.
- the driver (s) 25 protrude into the interior of the drum 11 with fork-like projections or ribs 40 such that they let the crop 41 to be broken down trickle down from above, thereby effectively utilizing the dry air and a better whirling up of the seed hair is achieved.
- These fork-like driver ribs 40 are arranged on a plane at the edge of the drum along the axis of rotation 24.
- the aspirated, pre-cleaned material is introduced into FIG the separation chamber 13 is guided into tubes 50 which are grooved (ie not smooth-walled on the inside) and / or which have rough or uneven inner walls and / or which have obstacles, for example rod-shaped obstacles 51, in their interior.
- tubes 50 which are grooved (ie not smooth-walled on the inside) and / or which have rough or uneven inner walls and / or which have obstacles, for example rod-shaped obstacles 51, in their interior.
- the suctioned, pre-cleaned material is fed into pipes before being introduced into the separation chamber 13, in which pipes are confused, for example, by a curved or spiral staircase course and / or by sudden changes in direction and / or sudden changes in diameter. air currents are generated. As a result, seeds still associated with the seed hair are separated from the hair.
- the methods of any pretreatment, the opening of the fruit capsule and the cleaning are expediently fine-tuned to the conditions of the respective seed fiber plant and its degree of ripeness.
- the method is used to harvest and obtain a fiber material (21) suitable as a raw material for insulation purposes or for the production of nonwovens or as a filler or upholstery material from the poplar, willow, daisy or similar plants.
- a fiber material (21) suitable as a raw material for insulation purposes or for the production of nonwovens or as a filler or upholstery material from the poplar, willow, daisy or similar plants.
- closed fruits of poplar, willow, daisy or similar plants are dried and opened in a treatment room (17) of a device (1) by means of an air stream and moved in the treatment room (17) in such a way that that in the fruit capsules (19) contained fiber material (21) from the others Fruit components is dissolved.
- a simple and feasible extraction and use of another vegetable fiber material was developed.
- the process can also be used to obtain cotton or kapok.
- seed-free material does not necessarily have to be obtained by the processes mentioned, since there is also the possibility of gentle subsequent cleaning using known carding / carding machines or other machines.
- the most important feature of the processes and process combinations mentioned is that the fibers can be obtained much more gently than in previously known Egrenier processes, or that very fine fibers can only be obtained.
