Definitions
- the invention relates to a pulper with a shaft on which a spiral is arranged, and to a method for the treatment of composite materials.
- Pulpers with a shaft on which a spiral is arranged are known in various embodiments.
- the spiral serves to circulate the materials to be treated in the pulper, in particular of biological materials or residual paper.
- these materials are destroyed by intensive grinding and mixing and are preferably comminuted to fibers.
- the invention is based on the object to further develop such a pulper.
- a slotted basket in the middle area of the pulper favors the material flows. This standard baskets can be used in the field of currently available on the market pressure sorters.
- An advantageous embodiment provides that the two spirals are arranged on the same shaft. Depending on the embodiment of the spirals, after rotation of the helix and in the direction of the drive of the spirals, different flows occur in the reaction space of the pulper. Here, embodiments are preferred in which two flows meet in the central region of the reaction space, which cause a high friction of the material in this area.
- an outlet is provided radially from this area, which can be designed as a screen basket.
- Such a pulper may conventionally have a screen plate in the lower region. It is advantageous, however, if the spirals are surrounded by a strainer basket.
- the pulper has a feed screw in the upper region of the pulper.
- the material flows are optimized by the pulper having a slotted basket radially outside the area between the spiral and the opposite spiral.
- basket preferably a known basket of a pressure sorter can be used.
- Such a basket is preferably arranged with different openings around the spirals.
- successive units may have baskets with cylindrical hole areas, the axial length of the baskets varying.
- the radius of the baskets can also vary.
- a fibrillating grinding is achieved by the pulper having a basket with grinding media.
- the pulper has a basket of sand as a grinding media.
- the sand can be a conventional sand which is cleaned by repeated use in the pulper. But it can also find a quartz sand with a special grain size used, which is tailored to the material to be treated.
- the features of the basket and the grinding media are also essential to the invention regardless of the formation of the spirals.
- the invention is further based on the object to present a method for the treatment of composite materials, with which the composite materials can be decomposed in a simple manner again into recyclable residues.
- the process can also use a conventional non-perforated pulper to intensively treat the composites with the addition of sand as a grinding media.
- the pulper or subsequently the pulps can be separated.
- the rejects are separated into a plastic-containing fraction and a metal-containing fraction.
- the sand can be separated with the metal-containing fraction.
- air classifiers or melting processes can be used to separate the fractions from each other.
- the pulps can first be removed in the pulper. Subsequently, the rejects are separated into a plastic-containing fraction, in particular polyolefins and / or polyethylene, and into a metal-containing fraction, in particular aluminum.
- the sand and the aluminum can be separated by an air classification or a melt or by sieving.
- FIG. 2 shows a cross section through a pulper with a counter-rotating spiral arranged on a further shaft
- FIG. 3 shows a pulper with a plurality of successively arranged units
- FIG. 4 shows a pulper with a plurality of units and water feeds provided between the units
- FIG. 5 shows a heavy-duty catcher with radial feed and a central one
- the pulper 1 shown in FIG. 1 has a heavy part catch 2 in the upper area in order to convey with a racket 3 heavy parts radially outwards and into the heavy part exit 4, while the lighter parts reach the supply spiral 5 in the radially inner area.
- the feed spiral conveys the millbase into the reaction space 6, in which a first spiral 7 conveys the millbase in the middle of the reaction space upwards, so that it is pressed downwards at the edge of the reaction space. Thereafter, the reaction material passes further down into the engagement of the opposing second spiral 8, which conveys the millbase in the middle of the reaction space downwards and thus in the radially outer lower region of the reaction space upwards. Thus arises in the central region of the reaction chamber 6, an increased friction between the material to be ground.
- the ground material then passes in the outer region of the reaction space 6 into the region of the screen plate basket 1 1.
- This screen basket 11 has different slot sizes in order to sort the ground material.
- the regrind therefore passes through different regions 10 of the screen basket with different slot or hole sizes, in different chambers 12, through which it leaves the pulper 1.
- the material to be ground 9 passes through the middle region 10 of the basket 11 into the chamber 12, via which it is removed from the system.
- the material to be ground 9 passes through the middle region 10 of the basket 11 into the chamber 12, via which it is removed from the system.
- the material to be ground 9 passes through the middle region 10 of the basket 11 into the chamber 12, via which it is removed from the system.
- the grist 13 reaches the chamber 14 and in the upper part of the material 15 reaches the chamber 16th
- a plurality of chambers are arranged around the reaction space 6, which make it possible to remove different sortings from the reaction space 6 through different slot or hole openings in the strainer basket 1.
- a drive (not shown) below the pulper makes it possible to rotate the shaft 17 inserted into the reaction space through the packing 18.
- the counter-rotating spirals 7, 8 convey the ground material into the middle region of the pulper.
- the spirals are formed as opposite spirals and preferably arranged on the same shaft.
- the spirals can be designed so that they promote the material in the region of the shaft to each other or promote in the opposite direction. Both leads to the fact that the material in the central region of the reaction chamber 6 meets each other and is ground by the resulting friction.
- the pulper 20 shown in FIG. 2 has a first spiral 21 on a shaft 22 and a second spiral 23 on a shaft 24.
- the shafts 22, 24 are separated from each other so that they can be driven in different directions.
- the ground material 25 passes centrally with the spiral 21 conveyed into the reaction space 26 of the pulper 20. In this reaction space creates a flow which causes a friction between the flowing millbase.
- the millbase passes as a pulp through a cylindrical screen plate 27 into an outlet 28, while the residue leaves the pulper through an exit 29.
- a good separation process is achieved either by passing the regrind several times through a single-stage reactor. This is done by a batch operation with an external circuit.
- a Multi-stage circuit proposed, for example, a reactor 30 may be used, as shown in Figure 3.
- the pulper shown in Figure 3 can be placed vertically like the other pulpers shown.
- the output 36 should be closable to prevent leakage of the pulper.
- the outlet can also be pulled as a tube up to the uppermost level of the pulper, so that the opening of the outlet is approximately at the level of the pulp inlet. This prevents the outlet from creating too much suction that pulls the liquid out of the pulper.
- An advantageous embodiment provides that the pulper is placed horizontally so that the units 31 to 35 are juxtaposed and not one above the other. The pulper then comes out with a relatively small ceiling height.
- the pulper 40 shown in FIG. 4 has three units 41, 42, 43, which are arranged one behind the other on a shaft 44.
- the ground material passes at the entrance 45 into the pulper and from there to the first Unit 41.
- pulp 46 passes through a cylindrical screen basket 47.
- the material to be treated is conveyed through a passage 48 into the second unit 42.
- the fabric is further treated and pulp is discharged through a cylindrical screen basket 49.
- the residue passes through a passage 50 in a third unit 43 with a further screen basket 51.
- the axial extent of the screen baskets 47, 49, 51 arranged one behind the other decreases more and more.
- the pulper 40 has three water inlets 52, 53, 54, of which the first water inlet 52 is arranged opposite the substance 45 to be treated, while the further water inlets 53, 54 are arranged between the units 41, 42 and 42, 43 , It is thereby achieved that the total material density in each pulper can be maximized by supplying as little water as possible. Nevertheless, more water can be supplied than would be possible if only at the entrance of a water inlet 52 would be provided.
- FIG. 5 shows a heavy section catch 60 in plan view and as a side view.
- Such Schwermaschinefang can be preceded by a pulper, if necessary, to mix without digestion effect, to separate, dissolve and deposit heavy parts. The material is shredded if necessary and arrives at the entrance 61 in the Schwerteil catch 60.
- the rendering step of deinking is strongly promoted.
- the printing ink is dissolved in the first pass of the paper (possibly using the usual chemistry) and washed out with a little water. Little water is used to minimize fiber losses.
- higher degrees of whiteness are achieved than with the known treatment. This is because the remaining black particle size distribution is shifted upward and thus leads to a lower gray tone - due to the lower specific surface area. This ultimately results from the significantly shorter residence time in the shear zone (kappa effect).
- the conditioner can combine the following treatment steps in a single aggregate:
- Entstuf ensortierers the usual stock preparation in the connection or as a conclusion of a multi-stage sorting cascade.
