Definitions
- the invention relates to a treatment plant for biowaste.
- bio-waste collected in this way is collected from the garbage disposal at regular intervals and fed to a composting plant.
- large plants have been set up, especially in large cities, in which large amounts of bio-waste are processed into so-called bio-compost with comparatively large construction and operating costs, in particular because of the associated odor pollution.
- the object of the invention is to provide a treatment plant for biowaste which can also be used in smaller municipalities and which in this context satisfies both economic and ecological requirements.
- this processing plant should reduce odor pollution inside and outside the plant to a minimum and be constructed in such a way that the extremely stressful sorting of organic waste can be avoided for the workers working in it.
- the processing plant for solving this problem is characterized by
- At least one closable mixer-crusher for processing a starting material
- a measuring device for acquiring measurement data of the starting material
- a programmable control system which is loaded with the recorded measurement data and which is connected to the feed device and by means of which the supplements according to the type and quantity can be fed to the starting material in accordance with the recorded measurement data;
- an automatically operating viewing and sorting device that follows the at least one mixer-shredder
- the starting material is either delivered bio-waste or bio-compost obtained from the delivered bio-waste.
- the organic waste which is usually collected in organic bins separately from other waste, is an inhomogeneous one
- the invention is based, inter alia, on the knowledge that the bio-waste collected and delivered from bio-bins has a pH value well below the neutral value, mostly at 4, and that the above-mentioned fermentation and putrefaction processes are anaerobic processes which are preferably acidic Mi ⁇ lieu expire.
- the processing plant according to the invention contains a closable mixer-shredder, so that the odor pollution for the environment is reduced by this alone.
- the delivered bio-waste is automatically mixed with additives, which dull the acidity of the delivered bio-waste and bind the liquid contained in it.
- the neutralization inhibits the aforementioned fermentation and putrefaction processes, so that the neutralized material no longer emits any notable odor.
- the organic waste in the mixer-shredder is converted in a comparatively very short processing time to an odorless, homogenized material of such a consistency that it can be piled up to form rotting piles and thus converted into biocompost.
- the otherwise pre-rotting together with the associated space and time required can therefore be omitted.
- the material discharged from the mixer-shredder has different grain sizes and contains foreign components which, according to the invention, are removed by an automatically operating viewing and sorting device.
- This viewing and sorting device advantageously contains a screening device, a separating device for light materials and a magnetic separator for magnetic foreign components; Furthermore, a separating device for metallic, non-magnetic foreign components and a separating device for stones can be provided.
- the above-mentioned, purely mechanical and therefore automatically operating devices are preferably arranged in such a way that the foreign components are separated off before composting.
- the processing plant according to the invention therefore dispenses with the otherwise conventional manual sorting, which is extremely stressful for the workers involved.
- the organic compost obtained from the rotting rent is a material that experience has shown that the nutrient content is too high, but is also not odor-free to the desired extent. In addition, it lacks some constituents that should be contained in the finished substrates depending on the respective intended use.
- the Biokom ⁇ post can therefore not be used everywhere as a finished substrate, but requires further processing. For this purpose, it is necessary to provide the organic compost with additives that are matched to the intended use of the respective finished substrate.
- Mixer-shredder which was used for the pretreatment of the bio-waste, can be loaded with the bio-compost and receives the necessary supplements for the production of the desired finished substrate. After mixing and shredding, the organic compost mixed with the additives is sufficiently homogenized for the respective use. The finished substrate is then obtained in the desired grain size after passing through the screening device.
- the processing plant according to the invention therefore uses essential components of the device in two ways, namely once for the pretreatment of the bio-waste for the production of a material that can be layered into rotting rents for the production of bio-compost and further for the production of the desired finished substrate from the bio-compost thus obtained.
- two mixer-shredders can be provided and operated alternately in such a way that one mixer-shredder can alternately be fed with the starting material and the additives while in the other mixer-shredder the input material can be mixed and comminuted and the mixed and comminuted material can be discharged therefrom.
- a feed device is assigned to each of the two mixer shredders, that the feed device contains an extendable conveying device, and that the conveyor runs from the discharge devices of the two mixer shredders to the viewing and sorting device.
- a processing plant designed in this way is distinguished by the fact that the mixer-shredders are fed alternately, thus permitting continuous operation of the processing plant. - -
- an automatically working processing plant which can be created and operated especially for smaller municipalities from an economic and ecological point of view, in particular also because it enables both the pretreatment of Biowaste to Biokom ⁇ post as well as the production of the desired finished substrates can optionally be carried out continuously.

- the viewing and sorting device 6 described below can contain all or only some of the components specified in the exemplary embodiment shown and described, as required. It initially contains a screening device, which in the exemplary embodiment shown is designed as a wave screen 34, which consists of a plurality of rotating shafts with disks arranged thereon at certain intervals.

- the biowaste usually shows an acidic reaction up to pH values of 4. Since these pH values favor odor-intensive, anaerobic fermentation and putrefaction processes and, furthermore, the structureless, liquid-containing material only under very specific conditions in difficult ratios to rotting rents can be stacked up in which the organic compost is formed, a pretreatment must be provided.
- the first storage container 14 of the feed device 5 accordingly contains a neutralizing agent such as lime, which is added to the biowaste to dull the acid level, and the second storage container 14 contains a thickening agent such as stone flour, which absorbs liquid.
- the feed hopper 24 of the feed device 22 is loaded with a structure-forming material, which is selected from straw, wood chips, sawdust, rotting compost, green waste compost, peat-like material and similar materials and structures the informal mass, whereby the layering of the material enables rents to be made ⁇ is light.

- the material pretreated in this way is suitable for the subsequent stacking to Rotte ⁇ rent 7. It no longer contains any undigested constituents such as fruits, vegetables and others, which form 7 densifications in rotting pots, so that there would be anaerobic fermentation and putrefaction processes.
- the pre-treated material is fed via the discharge device 30 and the conveyor 32 to the viewing and sorting device 6, in which the material pre-treated in the mixer-shredder 2 is subjected to a screening and sorting in which, in connection with the shaft sieve 34, light materials by means of the separating device 40, metallic non-magnetic foreign components by means of the separating device 46, magnetic foreign components by means of the magnetic separator 54 and steep ne can be separated from this material by means of the separating device 58.
- the second conveying device 38 is covered and out of operation.
- the sieve passage and the sieve residue are taken up by the discharge conveyor 52 and delivered to the steep conveyor 60, which piles up the compostable material into a heap at a predetermined location.
- the material heaped up on the stockpile is picked up by a wheel loader and piled up to form a red heap 7 which is triangular or trapezoidal in cross section.
- the material decomposes to bio-compost within a period of 6 to 8 weeks.
- the rotting piles 7 are implemented one or more times for adequate ventilation, in order to avoid local putrefaction processes and the associated processes . To a large extent exclude odor pollution.
- the organic compost is removed from the rotting rent 7 by means of a deliverer 8, such as a wheel loader, and input into the mixer-shredder 2.

- the conveyor 32 extends over the discharge devices 30 of the two mixer-shredders 2, so that it can take up the mixed, shredded and homogenized material from both mixer-shredders 2.
- this arrangement works as follows: A first mixer-shredder 2 is charged with bio-waste and receives the necessary supplements from the associated feed device 5.
- a second mixer-shredder 2 already contains bio-waste and the necessary aggregates and is in operation in which the input material is mixed, crushed and homogenized.
- the homogenization process in the second mixer-shredder 2 and the discharge process of the homogenized material on the conveyor 32 take place.
- the second mixer-shredder 2 is then free for re-loading with bio-waste, while the homogenization process and the discharge of the homogenized material take place in the first mixer-shredder 2.
- the processing system 10 modified in this way can also be operated continuously in the second mode of operation for producing the respectively desired finished substrate.
- FIGS. 5 to 7 show a treatment plant 66 as a second exemplary embodiment; parts which are also contained in the first exemplary embodiment according to FIGS. 1 to 4 are provided with the same reference numerals.
- the first side view of FIG. 5 shows the mixer-shredder 2 and the feed device 5 with storage containers 14 on stands 18, and the discharge devices 16 for the respective supplements.
- the storage containers 14 are arranged in a row above the conveyor to the mixer-shredder 2; the conveying device is designed here as a common belt conveyor 68 and a first ascending conveyor 70 leading to the mixer-shredder 2.
- the mixer-shredder 2 is charged in one of the ways described above.
- FIG. 6 is a side view of the processing plant 66 from the side opposite to FIG. 5.
- a second ascending conveyor 72 emerges from the mixer-shredder 2 and leads to an intermediate bunker 74 for receiving the starting material mixed and comminuted with the additives.
- the intermediate bunker 74 contains a conveyor belt 76 at the bottom, which feeds the introduced material to the conveyor 32 through a passage 78, which is designed here as a conveyor and leads to the viewing and sorting device 6.
- the volume of the intermediate bunker 74 is larger than that of the mixer-shredder 2.
- the material discharged from this accumulates in front of the passage 78, which has a limited passage cross section; This leads to a stabilization and adaptation of the material flow to the throughput of the subsequent viewing and sorting device 6.
- the screening and sorting device 6 contains a screening device in the form of a screening drum 80 and a wind sifter 88.
- the screening drum 80 is known per se and is commercially available (for example, model SM518St, Werner Doppstadt, Voßnackerstrasse 67, D-42555 Velbert); it is therefore not described in more detail here.
- a reversible first conveyor device 82, on the input side a second conveyor device 84 running transversely thereto for receiving the screen passage and on the output side a third conveyor device 86 for receiving the screen residue are assigned.
- the first and third conveying devices 82, 86 extend into the air classifier 88.
- the third conveying device 86 is assigned two spring rotors 87 which can be rotated during operation and whose spring steel arms 89 protrude into the sieve residue.
- the stirring movement of the spring steel arms 89 brings the light substances onto the surface of the sieve residue conveyed by the third conveying device 86, whereby the subsequent separation of the light substances in the air classifier 88 is promoted.
- the wind sifter 88 shown in section in FIG. 7 contains a blower 90 and deflection means 92 for the air flow generated by the blower 90.
- An impact drum 94 is arranged vertically between the end of the third conveyor device 86 and the end part of the reversible first conveyor device 82; laterally offset and axially parallel thereto there is a catch drum 96 with a scraper 98, under which the above-mentioned collecting container 44 for light substances is arranged.
- the air classifier 88 In operation of the air classifier 88, the sieve residue falling from the end of the third conveying device 86 is exposed to a first air flow from the deflecting means 92, which is directed laterally into the space between the third conveying device 86 and the impact drum 94.
- the material thrown off by the baffle drum 94 is exposed to a second air flow from the deflection means 92, which is directed from below to the space between the baffle drum 94 and the intercepting drum 96. Both air streams carry light substances contained in the sieve residue, from which they are deposited on the interception drum 96, from where they are conveyed into the collecting container 44 by the stripper 98.
- the falling sieve residue falls on the discharge conveyor 52, which follows the air classifier 88 and, in this embodiment of the processing plant, runs transversely and opposite to the second conveyor device 84.
- a magnetic separator 54 is also arranged on the discharge conveyor 52 here.
- the separating device 46 for separating metallic non-magnetic foreign components and / or the separating device 58 for stones can also be provided here.
- the second conveying device 84 is then out of operation.
- the first conveyor device 82 is reversed.
- the finished substrate obtained on the first conveying device 82 as a sieve passage then reaches the storage location or the packaging device 9 via the second conveying device 84. Meanwhile, the remaining sieve arrives via the third conveying device 86 and through the air classifier 88 on the discharge conveyor 52 and is poured on heap.
- FIG. 7 gives an overview of the entire processing plant 66 which, like the processing plant 10, is supplied with energy centrally by a conventional generator and whose central control 4 is accommodated in a control cabinet.
- the row of storage containers 14 with the belt conveyor 68 is arranged parallel to the ascending conveyor 72, the intermediate bunker 74 and the conveyor 32, so that overall there is a space-saving construction.
- the treatment plants 10 and 66 described above enable the economical and ecological treatment of bio-waste even in smaller municipalities.
- the processing takes place economically because the installation and operating costs of the processing plants are also affordable for smaller municipalities and because one and the same plant is used for the implementation of two different processes, namely for the pretreatment and conversion of the bio waste into bio compost as well as for the production the most diverse finished substrates from the biocompost obtained by the pretreatment.
- the preparation takes place in particular re largely automatically, so that the manual sorting of organic waste can be dispensed with, which represents an extraordinarily high burden for the workers.
- Wei ⁇ ter has a favorable effect in that the mixer-shredder 2 allows the otherwise usual pre-rotting process to be dispensed with, which results in a considerable saving in space, time and work processes.
- the treatment is also carried out in an ecological manner, because only comparatively short transport routes and therefore only minor traffic loads arise for the delivery of the bio-waste, because the pretreatment takes place in the closed mixer-shredder, whereby the otherwise associated, significant odor pollution is avoided, and because the entire preparation process up to the production of the practically odorless finished substrates is carried out under conditions under which odor pollution inside and outside the plant is reduced to an absolute minimum without the need for expensive filter devices and their used filters represent an environmental pollution themselves.
