Description

[0001] The invention relates to a processing plant for processing a mixture of waste glass according to the preamble of claim 1.

[0002] It is known that used glass is collected as waste glass and recycled. To avoid waste and save energy, the collected and processed waste glass is melted down as part of the recycling process and at least partially used in the glass melt during the production of glassware.

[0003] However, processing waste glass is relatively complex, as the waste glass mixture can contain undesirable substances and is not collected in a sufficiently pure form to meet recycling requirements. Therefore, a preliminary process is necessary, usually in a processing plant, to remove unwanted components and separate the glass constituents, so that a cleaned waste glass mixture suitable for recycling can be provided.

[0004] Known processing plants for processing waste glass mixtures comprise, in addition to a feeding device by means of which the waste glass mixture can be introduced into the processing plant, various sorting, classifying, and separation devices with which unwanted solids can be removed from the waste glass mixture and the waste glass mixture can be sorted according to size and / or color. The various devices and functional components of the known processing plants for processing waste glass mixtures are connected to one another by suitable conveying devices in order to convey the raw materials or the mixture further.

[0005] The known glass processing plants are large-scale facilities, designed as individual units and then assembled at the respective user's site with the help of specialists and local installation companies. This individual design approach for these large-scale glass processing plants has numerous disadvantages. In addition to the considerable effort required for the design phase, a large number of installation companies from other disciplines must be involved in the on-site assembly, which can lead to significant problems due to the multitude of interfaces. Furthermore, these processing plants are not very flexible, requiring a high throughput and a constant supply of large quantities of waste glass to operate efficiently. Consequently, modifications or expansions are difficult to implement in these individually designed large-scale plants.Furthermore, the existing processing plants cannot be pre-assembled, resulting in significant on-site installation costs at construction sites, which are often located in remote areas. Another disadvantage of these existing plants is that they typically cannot be dismantled and reassembled at a different location.

[0006] Furthermore, in processing plants of this type, a supporting steel structure is necessary to ensure the required stability.

[0007] Creating structural analyses for individually designed large-scale plants is extremely complex, prone to errors, and significantly limits flexibility. Furthermore, the extensive project planning, structural calculations, and increased on-site assembly effort result in a considerable time lag between the start of project planning and the commissioning of the processing plant.

[0008] From DE 200 14 898 U1, a device for processing a raw mixture of glass shards containing defective pieces is known, comprising a separation device for separating the raw mixture of glass shards into a first fraction of larger grain sizes and a second fraction of smaller grain sizes, a further separation device for removing defective pieces from the first fraction of larger grain sizes, a comminution device for comminuting supplied fractions of glass shards, wherein the material flow of the second fraction is directed into the comminution device and the material flows of the first fraction and at least a portion of the second fraction are combined at a collection point after the comminution device and the further separation device to form a product mixture.

[0009] In DE 20 2009 013 552 U1, a separation plant with equipment for separating components, in particular valuable and / or residual materials, from an inhomogeneous input material stream is described, wherein the equipment is arranged in floors, wherein components from the input material stream discharged by the equipment of a floor are transferred under the influence of gravity to at least one floor below or a base level.

[0010] Based on this prior art, the object of the present invention is to propose a new processing plant for processing a mixture of waste glass, which avoids the disadvantages of the previously known prior art. In particular, the processing plant should be flexible in its application, require as little effort as possible, and be usable while minimizing the static structures to be erected at the installation site.

[0011] This problem is solved by the features of claim 1.

[0012] The invention is based on the fundamental idea that the processing plant comprises several modules and at least one transportable frame. At least one module is then housed in this transportable frame. According to the invention, the frame houses at least one feed module, at least one ferrous metal module, at least one coarse separation module, at least one reading module, at least one classification module, at least one crushing module, at least one separation module, and / or at least one metal removal module. In this way, complex functional components of the processing plant can be pre-assembled as modules in a frame and transported to the installation site, while less complex components of the processing plant can be assembled directly on site.

[0013] Within the scope of the invention, the term "waste glass mixture" refers to a mixture of at least used glass, which can typically be in different colors such as clear, green, and brown glass and in the form of cullet, wherein the waste glass mixture may contain undesirable impurities of metal, stone, ceramic, porcelain, or organic substances. It is known to those skilled in the art that the purity of the glass mixture increases the more processing steps the glass mixture has undergone in the processing plant.

[0014] Within the scope of the invention, the term "feed module" relates to a device into which a mixture of recycled glass can be introduced and by means of which the mixture can be fed to the processing plant. The feed module can be loaded with the recycled glass mixture by a conveying vehicle, for example, a wheel loader. Preferably, the feed module is loaded with the recycled glass mixture in bulk form. For receiving and conveying the recycled glass mixture, the feed module can have a discharge chute and a conveyor belt and / or a bucket elevator. The use of a bucket elevator is particularly advantageous if the recycled glass mixture is already pre-sorted and a particularly compact design is desired.

[0015] In the context of the invention, an "ferrous metal module" relates to a component of the processing plant in which ferrous metals are separated from the waste glass mixture during a pre-sorting process. The separation of these ferromagnetic components of the waste glass mixture can be carried out, for example, using a permanent magnet.

[0016] Within the scope of the invention, the term "coarse separator module" refers to a device in which lightweight materials, in particular organic components and other coarse components, can be separated from the waste glass mixture. Coarse components are essentially those components of the waste glass mixture that, due to their size, are unsuitable for further processing in the recycling plant. These coarse components can be separated from the remaining waste glass mixture by means of a coarse screen. For the separation of lightweight materials, an organic separator can advantageously be provided, which separates the lightweight materials from the remaining waste glass mixture and removes them with an airflow.

[0017] The term "reading module" refers to a device in which solids can be removed from the waste glass mixture. This can be done, for example, by sorting out unwanted impurities or waste from the waste glass mixture at one or more manual workstations within the reading module. For this purpose, the waste glass mixture is conveyed along the workstations within easy reach of the employees working there, so that unwanted solids can be manually removed from the waste glass mixture.

[0018] Within the scope of the invention, the term "classification module" refers to a device in which the waste glass mixture can be separated into different fractions. Classification can be carried out, for example, using various sieves. Furthermore, unwanted foreign materials remaining in the waste glass mixture can be removed or sieved out during the classification process.

[0019] In the context of the invention, a "crusher module" relates to a device in which the components of the waste glass mixture can be crushed. Roller crushers are known to those skilled in the art for crushing waste glass mixtures. Preferably, a two-roller crusher is used in the context of the invention, by means of which the size range of the components of the waste glass mixture can be precisely defined as a result of the crushing process.

[0020] Within the scope of the invention, a "separation module" is a device in which ceramic components, stone components, and / or porcelain components can be sorted out of the waste glass mixture. Optical separation devices are preferably used within the scope of the invention to separate ceramic, stone, and porcelain components, which represent non-transparent impurities. Furthermore, it is conceivable that metals, heat-resistant glass components, and lead-containing glass components could also be sorted out of the waste glass mixture in the separation module.

[0021] A "metal removal module" within the scope of the invention is a device by means of which metals, in particular non-ferrous metals, can be separated from the waste glass mixture. Within the scope of the invention, non-ferrous metals are preferably sorted out by means of an eddy current separator. It is conceivable that, in addition to removing non-ferrous metals, ferrous metals are also removed in a magnetic drum arranged within the metal removal module. By means of the solution according to the invention, which involves mounting at least one module in a frame, the modules of the processing plant mounted in the frame can thus be pre-assembled at the manufacturer and delivered to the construction site together with the frame for the installation of the processing plant.The modules, which form pre-assembled functional elements of the overall system, drastically reduce the number of interfaces of the processing plant that need to be connected on the construction site.

[0022] The concept of pre-assembling the individual modules of the processing plant in transportable frames allows for the assembly of processing plants using a modular system. This makes it possible to create smaller and more flexible processing plants. If a processing plant is no longer needed at a particular location after a certain period of use, it can be dismantled and easily transported to another location by removing the transportable frames. Furthermore, the modularity of the system allows for the combination of numerous functional components and / or modules into a processing plant in virtually any configuration, which facilitates flexible modifications and easy reassembly of the processing plant at a different location.Furthermore, the modularity of the processing plant offers the advantage that the complex functional components do not need to be manufactured and / or assembled on-site, but can be delivered to the construction site as modules and simply connected there. Thus, only simple components of the processing plant, such as conveying equipment, or basic construction work, such as the construction of a foundation slab or the erection of support structures, need to be carried out on-site. As a result, this enables the construction of a processing plant with minimal effort and a minimal number of skilled workers required on-site.

[0023] Preferably, the processing plant is composed of at least one feed module mounted in a frame, at least one ferrous metal module mounted in a frame, at least one coarse separation module mounted in a frame, at least one reading module mounted in a frame, at least one classification module mounted in a frame, at least one crusher module mounted in a frame, at least one separation module mounted in a frame, and at least one metal removal module mounted in a frame.

[0024] Advantageous embodiments of the invention are the subject of the dependent claims.

[0025] It has proven advantageous to mount at least one label removal module on a frame. Labels and other residues of paper, metal, or plastic coatings are undesirable as residues on the cullet in the cullet mix, as they restrict further processing and the melting of the cullet mix. In particular, such label residues complicate separation, sorting, and / or classification in downstream process steps. Preferably, the coating residues are abraded by means of at least one conveying paddle, which generates the necessary friction within the cullet mix to detach the adhering residues. Advantageously, dust and / or organic residues can also be removed during the label removal process.

[0026] It has also proven advantageous to include at least one dust collection module in a frame. In principle, centralized or decentralized dust collection for a waste glass processing plant is conceivable. However, centralized dust collection has proven advantageous. Preferably, the dust collection module, housed in a frame, is connected to the main dust-generating components of the processing plant via piping. The exhaust air contaminated with dust particles is fed to the dust collection module, where solid ceramic components are separated from the gas. The cleaned exhaust air can then escape from the dust collection module via an outlet.The dust removal module is particularly preferably connected via pipelines to at least one separation module in order to extract the dust-laden exhaust air generated during the sorting of ceramic components, stone components and / or porcelain components and to feed it to the dust removal module.

[0027] It is also conceivable that at least one color sorting module, in which the components of the waste glass mixture can be sorted by color, is mounted on a frame. Separating the waste glass mixture according to glass color ensures a high recycling rate and consistent quality of the products manufactured from it. The production of clear glass, in particular, places high demands on the quality and purity of the waste glass mixture, and even with brown and green glass, a certain percentage of off-colors must not be exceeded. Exceeding such permissible off-color percentages can be prevented by providing a color sorting module. Within the scope of the invention, a color sorting module equipped with optical sensors is preferably used.An optical color sorting module enables resource-saving, especially in terms of personnel and time, as well as reliable sorting of the waste glass mixture by color.

[0028] It is conceivable that the color sorting module could be integrated into the separation module, thus enabling the sorting of ceramic, stone, and / or porcelain components, as well as the color sorting of the waste glass mixture, all within a single module. This would advantageously reduce the installation space required for the processing plant, the number of interfaces, and the effort required for assembly and maintenance.

[0029] It has also proven advantageous for the separation module to include an optical sorting system. The optical sorting of ceramic, stone, and / or porcelain components from the waste glass mix enables the reliable, personnel-independent removal of these unwanted components. Furthermore, the optical sorting system can be used to separate other unwanted components from the waste glass mix, such as heat-resistant glass, leaded glass, or magnetic metals, in addition to ceramic, stone, and porcelain.

[0030] Within the scope of the invention, it has proven advantageous for the processing plant to have at least two separation modules, wherein the separation modules are arranged sequentially along the material flow of the waste glass mixture through the processing plant. In other words, the material flow of the waste glass mixture does not pass through the at least two separation modules in parallel, but rather the waste glass mixture is first fed to a first separation module, where initial sorting takes place, and then the remaining waste glass mixture is fed to one or more further separation modules. Thus, a two-stage sorting process is carried out along the material flow of the waste glass mixture through the processing plant. This increases the reliability of the sorting and the quality and purity of the waste glass mixture intended for remelting.Particularly preferred is the inclusion of a color sorting module in each sorting stage, enabling color separation of the waste glass mix at every stage. Even more preferred is the first sorting stage, in which a first separation module separates the waste glass mix into three fractions: a first fraction of brown and green glass, a second fraction of clear glass, and a third fraction of ceramic, stone, and porcelain components (CSP). Only the clear glass fraction is then fed into the subsequent second sorting stage and, due to the increased purity requirements for recycling clear glass, is subjected to further sorting in at least one additional separation module.It is conceivable that in the second stage of sorting the clear glass, the removal of the KSP components is omitted, and only color sorting is carried out using a color sorting module integrated into the separation module. This would remove the green and brown glass components remaining in the clear glass fraction after sorting in the first stage. This would advantageously achieve a purity level sufficient for remelting in both the clear glass fraction and the brown and green glass fractions of the recycled glass mix.

[0031] The storage quantities required for the waste glass mixture are very large, as a processing plant can have an exemplary throughput of 20 tons of waste glass mixture per hour. These large quantities are regularly stored independently of the processing plant and fed to the feed module of the processing plant according to the invention. For simple and loss-free feeding of the waste glass mixture to the processing plant, it has proven advantageous if a feeding device is arranged on the feed module, through which the waste glass mixture can be fed to the feed module. Preferably, the feed module, which forms a complex functional component of the processing plant, is mounted in a frame and transported to the construction site pre-assembled, while the feeding device is manufactured on site and attached to the feed module.Since the feeding device is a relatively simple component of the processing plant, there is no need to pre-assemble it and place it in a frame.

[0032] It has proven particularly advantageous if the feeding device for the waste glass mixture is designed in the form of a filling funnel. Such filling funnels can be easily manufactured on-site, for example as sheet metal constructions, and arranged on the feed module. Preferably, the filling funnel is positioned above the feed module. It is intended that the filling funnel can be filled using a bulk material transport device, such as a tipper truck or an excavator.

[0033] The feeding device itself is primarily intended for supplying the waste glass mixture to the processing plant. To enable a continuous supply of waste glass mixture to the processing plant, it is advantageous if a small quantity of the waste glass mixture can be temporarily stored in the feeding device, particularly in the filling hopper. This allows the filling hopper to be filled discontinuously with waste glass mixture using transport machines, while continuously supplying waste glass mixture to the processing plant. The temporarily stored quantity of waste glass mixture depends on both the size of the feeding device and the throughput of the processing plant.For example, it may be provided that the quantity of waste glass mixture is temporarily stored in the feeding device, corresponding to the throughput of the processing plant in 0.5 hours, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours or 10 hours.

[0034] Furthermore, it has proven advantageous if the processing plant includes at least one storage facility for storing at least one sorting component of the waste glass mixture. Within the scope of the invention, the term "sorting component" refers to a component that is separated during the processing of the waste glass mixture in the processing plant. This can include, for example, unwanted foreign materials in the waste glass mixture, such as metals, ceramics, stone, or porcelain, but also the fractions of clear glass, green glass, or brown glass intended for recycling. Preferably, the storage facilities are constructed on-site as simple components of the processing plant and are not mounted on racks or transported to the installation site pre-assembled. Preferably, the storage facility is designed as a bunker for receiving the sorting components. Particularly preferably, one bunker is provided for each component separated from the waste glass mixture.

[0035] Within the scope of the invention, it has been found to be advantageous to provide at least one conveying device for connecting the modules. Stationary conveyors are preferably used as conveying devices. Belt conveyors are even more preferred, as they advantageously enable a long conveying length, high conveying volume, and high conveying speed with relatively low drive power. While it is conceivable to mount the conveying device in a frame and transport it to the installation site of the processing plant in pre-assembled sections, it has proven advantageous to manufacture and assemble the conveying device on-site at the installation site of the processing plant.The relatively straightforward assembly of the conveying system can be carried out on-site with minimal skilled personnel, thus avoiding transport costs that would be incurred when installing the conveying system in racks and moving the racks to the installation site of the processing plant. This approach also reflects the fundamental concept of the processing plant according to the invention, namely that complex functional components of the processing plant are pre-assembled as modules in a rack and transported to the installation site, while less complex components of the processing plant are assembled on-site.

[0036] Therefore, depending on the complexity of the drive system, it is conceivable to pre-assemble it in a frame and only connect it to other components, such as the belts and the supporting structure of a conveyor system, at the installation site. A drive system can include not only a drive for a conveyor system but also a transfer unit for transferring at least part of the waste glass mixture to a downstream process step and / or a downstream component of the processing plant.

[0037] Furthermore, it is conceivable that the individual modules could be connected to a conveying system in any way. However, it has proven advantageous that at least the feed module is connected to the ferrous metal module via a conveying system, and / or the ferrous metal module is connected to the coarse separation module via a conveying system, and / or the reading module is connected to the metal rejection module via a conveying system, and / or the label removal module and the classification module are connected via a conveying system. This connection via a conveying system allows the modules to be spaced apart from one another within the processing plant, enabling the transport of large distances and volumes between the modules.

[0038] It has proven particularly advantageous if the frame is self-supporting. This allows for easy transport of the frames to the installation site of the processing plant, as well as the erection of the processing plant itself without additional supporting structures. Consequently, the separate steel structure typically erected at the installation site is eliminated. This minimizes not only the costs for the steel structure itself but also the effort required to create the corresponding structural analysis for the processing plant.

[0039] During the processing of waste glass, the resulting dust generation can pose an increasing problem, as dust emissions are often only tolerated in very small quantities. To solve this problem, it is therefore particularly advantageous if the rack has a closed outer wall that dust-tightly encloses a closed interior space within the rack. In this way, a dustproof shell can be created around the rack. If several racks are combined to form a section of the processing plant, the racks only have a dustproof wall on their outer surfaces, which together form the outer shell of the combined racks.

[0040] For quick and easy assembly of the processing plant at the installation site, it has proven particularly advantageous if the plant comprises several transportable racks, each holding one or more modules of the processing plant. By combining the racks, pre-assembled modules of the processing plant can be easily delivered to the construction site and, if necessary, removed again. Ideally, the individual racks are already fully wired and can be connected and put into operation simply by plugging them together with the other racks.Preferably, the processing plant is constructed from several transportable frames, wherein at least one frame is provided with a feed module, at least one frame with a ferrous metal module, at least one frame with a coarse screening module, at least one frame with a reading module, at least one frame with a classification module, at least one frame with a crusher module, at least one frame with a separation module and at least one frame with a metal removal module.

[0041] Furthermore, it has proven advantageous for a space-saving design of the processing plant and a simple material flow within the plant if the various racks of the processing plant can be arranged one above the other and / or stacked on top of each other. If the various racks are arranged one above the other and / or stacked, the material flow can occur easily from top to bottom, preferably solely by gravity. In addition, it is advantageous if the majority of the racks are self-supporting within the processing plant. Thus, even when combining multiple racks, the complex steel structure required for processing plants of this type can be avoided.In other words, the transportable frames form the basic structure of the processing plant or a section thereof, without the need for additional structural elements such as columns or beams. Preferably, the frames are designed in the form of a truss structure, with bracing provided by diagonally installed struts, the ends of which are connected at nodes.

[0042] To enable simple, resource-efficient transport of the racks, it has been found to be advantageous for the racks of the processing plant to be the size of a standard shipping container or half-container, or to be arranged inside a shipping container. In this way, all racks can be transported to the installation site of the processing plant by container transport, for example on so-called flatracks, and, if necessary, also transported away again from there. It is known to those skilled in the art that the term "flatrack" refers to a container without side walls or a roof. A flatrack can be designed with or without end walls and has the standard dimensions of ordinary standardized ISO containers, and it is known to those skilled in the art that the abbreviation ISO stands for the International Organization for Standardization.Preferably, the racks are designed in the size of a freight container or in the size of a freight half-container.

[0043] Further details, features, and advantages of the invention will become apparent from the following description of a preferred embodiment in conjunction with the dependent claims. The respective features can be implemented individually or in combination with one another. The embodiment is shown schematically in the figures. Identical reference numerals in the individual figures denote identical or functionally equivalent elements, or elements that correspond to one another with respect to their function.

[0045] Fig. Figure 1 shows a processing plant for reprocessing a mixture of waste glass consisting of different types, such as clear, brown, and green glass, as well as unwanted foreign materials or impurities. The processing plant essentially comprises racks 2a, 3a, 4a, 5a, 6a, 7a, 8a, 9a, 11a, and 16a, and the conveying devices 15.1, 15.2, and 15.3 connecting the racks. The dimensions of the racks correspond to the dimensions of transport containers or flatracks, or are dimensioned such that they can be arranged in a transport container, allowing the racks and their modules to be transported to the construction site for installation of the processing plant in pre-assembled form.The frames with the modules they contain are arranged on the construction site in such a way as to allow for the simple and rapid assembly of a fully functional processing plant for waste glass. In the illustrated embodiment, the processing plant comprises a feed module 2 mounted in frame 2a, with a feed device designed as a filling hopper 13.1 located above the feed module. The filling hopper 13.1 is designed so that it can be filled with waste glass using a transport vehicle 20, for example, a wheel loader. The waste glass is then conveyed via the feed module 2 to the ferrous metal module 3, which is mounted in frame 3a. In the ferrous metal module 3, ferrous metal components are separated from the waste glass during a pre-sorting process.The waste glass mixture is then conveyed via conveyor 15.1 to the coarse separation module 4 in frame 4a. In the coarse separation module 4, lightweight materials, particularly organic ones, are separated from the cullet of the waste glass mixture and removed. The remaining waste glass mixture is then fed to a sorting module 5 in frame 5a. In this sorting module 5, which in the illustrated embodiment is designed as a manual workstation, further coarse impurities and waste are manually removed from the waste glass mixture and disposed of. In the downstream crusher module 7 in frame 7a, the remaining waste glass mixture is crushed to a defined cullet size. Via the conveyor 15.2, which is designed as a conveyor belt or bucket elevator and is driven by the drive unit 16 housed in frame 16a, the crushed waste glass mixture is fed to the metal removal module in frame 9a.There, non-ferrous metals are removed, as well as any remaining ferrous metals after the initial ferrous metal pre-sorting in the waste glass mixture. Downstream of the metal removal module 9 is a label removal module 10, in which both labels adhering to the glass shards and other waste, particularly organic waste, are sorted out. The remaining waste glass mixture is transported from the label removal module 10 to the classification module 6, which is housed in rack 6a, via conveyor belt 15.3. In the classification module 6, the waste glass mixture is passed through various sieves, separating the material into different particle sizes and removing any remaining foreign materials. After classification, the waste glass mixture is fed to the separation module 8 in rack 8a. In the separation module, foreign materials such as ceramics, stone, and porcelain are removed using optical sorting.Furthermore, it is possible to sort out heat-resistant glass, leaded glass, and magnetic metals in the separation module 8. In the illustrated embodiment, the separation module advantageously includes a color sorting module 12, which is housed within the separation module 8 and thus within the frame 8a. The color sorting module allows the waste glass mixture to be sorted by color, in particular by brown, green, and clear glass. After processing, the individual components of the waste glass mixture are stored in storage facilities 14, in this embodiment in separate bunkers, so that the cleaned waste glass, which meets the requirements for remelting, can be easily removed from the storage facilities 14. In addition, the foreign materials and waste removed from the waste glass mixture during processing are also stored in separate storage facilities 14.To minimize dust emissions from processing plant 1, a dust extraction module 11, which is also pre-assembled in a frame 11a and transported to the installation site of processing plant 1, is provided. It can be seen that the frames 2a, 3a, 4a, 5a, 6a, 7a, 8a, 9a, 11a, and 16a can be arranged on a base plate or elevated, depending on the installation method. Furthermore, the frames 2a, 3a, 4a, 5a, 6a, 7a, 8a, 9a, 11a, and 16a are stackable and self-supporting. To further reduce dust exposure, racks 2a, 3a, 4a, 5a, 6a, 7a, 8a, 9a, 11a, 16a can be fitted with an outer wall, which is not shown here for the sake of clarity.

[0046] Fig. Figure 2 shows a feed module 2, which is mounted in a frame 2a, with a feed device 13 arranged above it, designed as a filling hopper 13.1. The feed module 2 includes at least one discharge chute 18 for receiving the waste glass mixture. In the illustrated embodiment, a hopper base 19 and a conveyor belt with a conveyor belt tensioning station 17 are also arranged in the frame 2a, which feeds the fed waste glass mixture to the discharge chute 18. By providing a hopper base 19 in the frame 2a, the filling hopper 13.1 can be easily arranged above the frame 2a and connected to the hopper base 19. This creates a simple filling hopper 13.1 that can be mounted at the installation site of the processing plant 1, allowing the processing plant 1 to be loaded with a transport vehicle 20. For easy filling of the filling funnel 13.1. As in the illustrated embodiment, it may be provided that an access ramp 21 is constructed as an access route to the filling hopper 13.1.

[0047] The Fig. Figure 3 shows a metal removal module 9 and a drive unit 16. The drive unit 16 serves to drive a conveying device (not shown here), for example, a conveyor belt, and is housed in a separate frame 16a. This allows the drive unit 16 to be delivered pre-assembled to the installation site of the processing plant 1, so that only the less complex components of the conveying device, such as the supporting structure, need to be assembled on site. The metal removal module 9 is housed in the frame 9a, and the metal removal module 9 shown in this embodiment comprises a vibrating trough 24, a magnetic drum 22 for separating ferrous metal components, and an eddy current separator 23 for separating non-ferrous metal components from the waste glass mixture.

[0048] The Fig. Figure 4 shows a frame 16a with a drive unit 16 and a frame 4a in which a coarse separation module 4 is mounted. The coarse separation module 4 shown in this embodiment comprises at least a coarse screen 25 for screening out relatively large foreign materials in the waste glass mixture and an organic separator 26 for separating, in particular, organic, lightweight materials from the cullet of the waste glass mixture.

[0049] In the Fig. The frame 5a shown in Figure 5 houses a reading module 5. It is evident that the reading module 5 has a device for manually sorting foreign materials from the waste glass mixture. The motor-driven reading belt 28 conveys the glass mixture past the manual workstations, allowing foreign materials to be manually removed and disposed of via the waste chutes 27. An overband magnet 29 located downstream of the manual workstations separates any remaining metallic components from the waste glass mixture.

[0050] Fig. Figure 6 shows a two-roll crusher 30, which is included as an essential component of the crusher module 7 in the frame 7a.

[0051] The two-roller crusher 30 allows for a defined crushing of the shards of the waste glass mixture.

[0052] In Fig. Figure 7 shows a frame 6a in which a classification module 6 is mounted. The waste glass mixture is fed to the classification module 6 via a conveying device (not shown), which is driven by the drive unit 16. In the screening unit 34, the waste glass mixture is separated according to the particle size fractions, in this case into fine fraction, small fraction, and large fraction. For example, a fine fraction can have particle sizes from 0 mm to 8 mm, a small fraction from 8 mm to 24 mm, and a large fraction from 24 mm to 50 mm. The fine fraction is fed via the fine fraction outlet 31, the small fraction via the small fraction outlet 32, and the large fraction via the large fraction outlet 33, either to a storage unit 14 or to a downstream process step.

[0053] Fig.Figure 8 shows two separation modules 8.1 and 8.2, each mounted in a frame 8a. The stacked arrangement of the frames 8a, and thus the provision of two separation modules 8.1 and 8.2 arranged one above the other, enables a two-stage separation process in the illustrated embodiment. The first-stage separation takes place in separation module 8.1, while the second-stage separation takes place in separation module 8.2. Separation module 8.1 comprises two three-way sorting units 38. One of the three-way sorting units 38 receives a small fraction via the small fraction inlet 35 and a vibrating trough 24, while the other three-way sorting unit 38 receives a large fraction via the large fraction inlet 36 and a vibrating trough 24. The three-way sorting devices 38 of the separation module 8.1 can be controlled via a control panel 37.In the three-way sorting unit 38, the waste glass mixture is separated into "Gramber," which is a mixture of green and brown glass, and clear glass, as well as unwanted foreign materials such as ceramics, stone, and porcelain. Furthermore, other unwanted foreign materials, such as heat-resistant glass, leaded glass, and metals, can be sorted out. The fractions produced during the three-way sorting process in the three-way sorting unit 38—namely, green / brown glass, clear glass, and foreign materials—are separately conveyed either to a storage unit 14 or to a downstream process step. In the present embodiment, the clear glass components of the waste glass mixture are conveyed from separation module 8.1 to the second stage of separation in separation module 8.2 and fed via a vibrating trough 24 to a two-way sorting unit 39. The two-way sorting device 39 is also controlled via a control panel 37.Due to the increased requirements for white glass during remelting, the second stage of separation in separation module 8.2 involves the further removal of green and brown glass components from the white glass fraction formed in separation module 8.1. The white glass fraction separated in separation module 8.2 is then fed to a storage facility 14 (not shown here), and the green and brown glass fraction removed in separation module 8.2 is also fed to another storage facility. This two-stage separation in separation modules 8.1 and 8.2 typically concludes the processing, so that after passing through separation modules 8.1 and 8.2, recyclable fractions of a waste glass mixture are available, which can be fed into a subsequent remelting process.
