Definitions
- the invention relates to a baffle reactor for comminuting composite material, comprising a cylindrical shell, in which a rotor is arranged and a filling opening for filling the composite material and a discharge opening for discharging the comminuted composite material.
- Baffle reactors are used to shred objects composed of different materials so that a material separation is possible.
- the objects are crushed by a impact stress with a high pulse transfer by means of rotating impact elements and separated into individual components.
- a baffle reactor is known with a cylindrical basic body, in which a rotor driven by a drive motor is arranged.
- the rotor is made of wear-resistant steel and has interchangeable at its propeller-shaped or wing-shaped ends
- baffle reactor removal openings In the shell region of the baffle reactor removal openings are arranged. These can be covered with slotted or perforated sheets, so that a differentiated discharge of comminuted particles in the desired particle size is possible.
- Beverage packages often include at least one polyethylene terephthalate (PET) packaging portion. This material can be recycled to high quality and, for example, to textile fibers
- PET-containing material does not heat up so much during comminution that the material properties change adversely.
- the invention has for its object to provide a baffle reactor for comminuting composite material, which allows a gentle comminution of temperature-sensitive materials.
- the impact reactor according to the invention for comminuting composite materials comprises a cylindrical jacket in which a rotor is arranged and a filling opening for filling the composite materials and a removal opening for discharging the comminuted composite material, wherein at least one further filling opening for a cooling medium is provided.
- Composite material does not overheat the composite material.
- the rotor may be provided with baffles arranged at the free ends of the rotor blades.
- the rotor can be rod-shaped Rotor blades or alternatively chains, ropes, sword-shaped rotor blades or wings have.
- the cooling medium comprises water.
- Water is particularly inexpensive and easy to use.
- Composite materials such as beverage packaging can be crushed particularly effectively and gently in a baffle reactor when the process is performed together with water. This is because the water filled in the baffle reactor mixes rapidly with the composite material. This dampens the water
- Contaminate and residues can be removed from the composite material. This is particularly advantageous in connection with the crushing of beverage packaging. Usually located in
- the result of the comminution is a comminuted, or in individual components separated and purified composite material.
- the cooling medium may comprise an additive.
- Additives are in particular those substances which facilitate the purification and separation of substances
- additives are, for example, surfactant-containing or alcohol-containing cleaning agents which dissolve beverage residues and the like.
- Other possible additives are solvents, which release, for example, adhesive labels or adhesive residues from the composite material.
- the removal opening may be associated with a classifier. This is particularly advantageous if there is a continuous discharge of the comminuted composite material from the impingement reactor. This is the case, for example, when the removal opening of the impact reactor is open at least during the comminution process. In principle, a batchwise operation is conceivable. This is especially the case when the residence time of the composite material in the impact reactor is very short.
- the classifier is designed as an air classifier. This allows effective separation of the film-like components from the material removed from the baffle reactor.
- the baffle reactor on a lid, which with the
- the further filling opening may be associated with the jacket and / or the lid.
- the cooling medium is preferably added simultaneously with the composite material in the baffle reactor space.
- the cooling medium may be liquid nitrogen, dry ice or a comparable cooling medium.
- the cooling medium is water, which is added via a filling opening in the baffle reactor space.
- the cooling medium may further comprise an additive.
- the crushed composite material can be continuously removed from the
- Impaler reactor space can be removed. Alternatively, the crushed
- Composite material batchwise be removed from the baffle reactor space In particular, in plastic, for example, made of PET beverage packaging are composite materials with a relatively low specific weight and a relatively low strength.
- a cooling medium is also introduced into the impingement reactor chamber, it is possible to prevent the composite material from being heated and thus from being prevented from being used further.
- the residence time is only fractions of seconds. This may be the case in particular if the rotor has a plurality of rotor blades arranged one above the other which can be arranged offset from one another on the same shaft. In this embodiment, a kind of labyrinth forms, which causes rapid comminution.
- Cooling medium water and the short residence time of the composite material of a few seconds in the impingement reactor chamber ensures that the composite material is separated only into its individual components. This may be due to the removal of the crushed composite material
- This can be in the form of a
- Wind sifter or be designed in the form of a sieve.
- the use of an air classifier has proven to be advantageous and very effective.
- FIG. 1 shows schematically an embodiment of the impact reactor according to the invention.
- Figure 1 shows a baffle reactor 1, or a
- the impact reactor 1 comprises a cylindrical shell 2 made of metallic material.
- a rotor 3 is arranged, which is provided with baffles 5.
- the rotor 3 is operatively connected to an electric motor 6, which is arranged outside the shell 2.
- the shaft connecting the rotor 3 to the electric motor 6 extends in the axial direction of the cylindrical jacket 2.
- the rotor 3 is provided with wings 4 which protrude radially from the shaft. At the ends of the free wings 4 are
- the baffle elements 5 are removably attached to the wings 4.
- the impact reactor 1 is closed at the rotor facing away from the end with a cover 7.
- the jacket 2 has a filling opening 9 for filling the composite material.
- the jacket 2 also has in the region of the rotor 3 a removal opening 8 for discharging the comminuted composite material.
- a further filling opening 10 is integrated for a cooling medium.
- the further filling opening 10 is formed as a pipe socket through which water can be passed into the limited by the jacket 2 and the cover 7 baffle reactor space.
- the removal opening 8 is a classifier 1 1 in the form of a
- the composite material is introduced via the filling opening 9 into the impingement reactor chamber. Furthermore, a cooling medium is added via the further filling opening 10 into the baffle reactor. The composite material is comminuted under the action of the rotor 3 and the cooling medium provided with the baffles 5 and finally discharged via the removal opening 8 from the baffle reactor space. Subsequent to the removal of the comminuted composite material, a classification by means of a
- Air classifier The removal of the shredded composite material from the
- Baffle reactor space is carried out continuously in the present embodiment.
- the device is also suitable for batchwise operation.
