Definitions
- the invention relates to a method and a device for the environmentally compatible preparation of containers, such as containers, barrels, cans with liquid residues therein and / or layers of residues adhering to them, such as paints, adhesives, plastics, wherein the containers can also consist of non-metallic material .
- containers such as containers, barrels, cans with liquid residues therein and / or layers of residues adhering to them, such as paints, adhesives, plastics, wherein the containers can also consist of non-metallic material .
- water residues from atmospheric influences can also occur in the containers.
- processes which essentially comprise the process steps known per se, such as crushing the containers, supercooling to embrittle the residual materials, separating and separating the reusable materials and disposing of the residual materials.
- devices which mainly consist of known shredding devices such as shredders, rotary tube coolers, separating and separating and disposal devices.
- the invention is therefore based on the object, the above. Generic methods and devices to be improved in such a way that their performance and availability are increased and energy consumption is reduced.
- the process steps known per se technically, physically and economically have been eliminated, so that the previous disadvantages are remedied if, prior to supercooling and shredding, the containers compress them according to the invention to increase the thermal conductivity and thereby squeeze out parts of residues from the containers and be separated.
- the method in accordance with claims 2 to 9, can be influenced in such a way that advantageously a piece size optimization and thus the increase in performance and availability of the method and the device can be achieved.
- the method can be designed in such a way that it can advantageously be largely automated by combining it with a control / regulation of the flow rate depending on the particular degree of preparation of the container components.
- the inventive design of the device according to claims 10 to 20 supports and reinforces the technical-economic effect of the method in its entire sequence.
- the compression of the applied containers with the increase in thermal conductivity leads to a reduction in energy consumption and to piece size optimization and ultimately to an increase in the efficiency of the process.
- the design of a roller press makes it possible to stretch, open or unlock the compacted surface structure of the containers, which further reinforces the effect already described.
- the invention is explained in the following embodiment.
- the drawing shows a schematic representation of a device according to the invention for processing containers with which the method can be carried out.
- the device essentially consists of a roller press 1 with rollers 1.1, a sieve-like grate 2 arranged underneath, a container 3 located under the grate, a rotor shear 4 arranged downstream of the roller press 1, a screw conveyor 5, a cooling device, e.g. a rotary tube cooler 6, with an outlet (not shown in more detail) to a hammer crusher 7 with hammers 7.1 pivotably arranged on a rotor and an anvil-like counter tool 7.2 and a lower grate 7.3, a cascade sieve 8 located under the grate 7.3 with a container 10 arranged underneath, a subordinate one Magnetic separator 9 and containers 11 and 12.
- the roller press 1 is adjustable with respect to the compression pressure and the speed of the rollers 1.1.
- the rollers 1.1 can advantageously be operated at different speeds.
- the containers to be processed are fed in the direction of the arrow to the opposing rollers 1.1 of the roller press 1 via feed devices (not shown).
- the containers are compacted and parts of residues, such as paint residues and water, are pressed or squeezed out.
- the container is compressed and the thermal conductivity increased.
- the compression process which is decisive for increasing the thermal conductivity, is further enhanced in its process-relevant effect when the compressed material of the container is stretched by the rollers 1.1 operated at different speeds relative to one another until the surface structure of the flat container is opened. If the lateral surfaces of the rollers 1.1 are additionally profiled or even tool-like, this effect of compression / stretching / material opening, which is important for the further process sequence, is attained to the maximum.
- the thus compressed, stretched or opened and flat material of the container reaches the rotor shears 4 as an overflow of the grate 2, in which the first and pre-comminution takes place by cutting at a relatively low speed.
- the container parts treated in this way enter the cooling device, e.g. the rotary tube cooler 6 it is expedient to form the bottom of the screw conveyor in a sieve-like manner in order to remove any residues separated by the crushing in the rotor shears before
- the rotary tube cooler 6 is supplied with a continuous and relatively homogeneous flow of compressed, pre-shredded pack parts. This enables time-saving and energy-saving supercooling, for example with liquid nitrogen, up to the embrittlement temperature of the residual substances R 2 still adhering to the container parts, since the compression / thermal conductivity effect and the proportion of the residual substances R 2 still to be embrittled have a particular effect here the previous steps are already reduced.
- the process flow is thus further expanded in terms of its performance, its reduced use of energy and its efficiency.
- the material cooled down to the embrittlement temperature of the residues R 2 from container parts is fed as feed material to the hammer crusher 7.
- the container parts that have been given in are finally separated from the embrittled residues predominantly by the impact energy.
- the actual idea of the invention can be advantageously used, for example by allows the design and effect of the hammer breaker 7 to be determined for this method and thus favorable conditions for the subsequent separation into single-variety fractions are created.
- the crushed container parts and separated, embrittled residues R 2 passing through the grate 7.3 are then passed over a sieving device, such as a cascade sieve 8.
- the embrittled residues R 2 are taken up by the container 10 to be disposed of as a screen underflow.
- the sieve overflow is over
- Spare sheet a magnetic separator 9 is subjected to a separation, for example into an Fe fraction F Fe for the container 12 and a non-iron / non-metal fraction F NE / NM for the container n.
- the latter fraction can be processed into further desired recyclable material fractions by means of a non-specific separation, not shown here.
- the compression according to the invention which is effective in terms of its effectiveness and technical-physical effect, also enables a sorting of reusable materials and residues to be disposed of before they are crushed and supercooled.
- the invention realizes a method and a device for the preparation of containers, which makes the process sequence environmentally friendly, energy-saving and with a continuous flow.
- the separation of the reusable fractions from the residual materials to be disposed of ensures a high degree of exploitation of valuable materials.
