Description

Technical Field

[0001] This invention relates to a system for storing and recycling bulk materials. The system includes a bulk material holding space with a bottom portion and a discharge port. The invention also relates to applications of the system and to vessels, land-based storage facilities, and hoppers incorporating the system. Background Technology

[0002] Today, large quantities of goods are transported globally via large ocean-going vessels or ships capable of long-distance voyages on the high seas. Similarly, large quantities of goods are transported over more moderate distances via inland waterways such as rivers and lakes. This large volume of cargo therefore necessitates considerable handling and storage, including, for example, in conjunction with reloading.

[0003] When transporting bulk cargoes or loads (such as coal or ore), bulk naval vessels or ships specifically designed for bulk cargo are typically used because of their capacity to handle bulk loads. Bulk carriers are usually equipped with large cargo holds covered by some form of hatch or cover, which is opened during loading and unloading of the cargo. When handling bulk cargo, cranes or similar equipment equipped with buckets are typically used to process the cargo.

[0004] Similarly, large onshore storage facilities are typically used to store bulk cargo. Bulldozers or similar equipment are commonly used in these facilities to distribute, reload, and unload bulk cargo.

[0005] In addition, bulk cargo can be temporarily stored and reloaded in a so-called hopper system.

[0006] However, more efficient reloading or unloading of bulk cargo can be achieved using so-called self-unloading systems, which can be installed, for example, on ships or storage facilities. In a self-unloading system, bulk cargo is automatically unloaded from the ship or cargo hold through gates located at the bottom of the space or hold. The space used to hold the cargo in a self-unloading system is typically equipped with steeply sloping sidewalls along which the bulk cargo slides toward the gates located at the bottom. From the gates, the bulk cargo is then typically transported away using conveyors, transport machines, or feed screws.

[0007] In self-unloading systems, bulk cargo is prone to jamming during unloading. Several reasons contribute to this. One reason is that the sidewalls of the space used to hold the cargo are not steep enough. Another reason is that the sidewalls of the space exhibit excessive friction due to material blockage or adhesion. Yet another reason is that the bulk cargo forms a wall during unloading. Yet another reason is that the bulk cargo arches, for example, over a gate. A further reason is that the material properties of the bulk cargo do not allow for free flow due to high internal friction, thus causing it to arch, for example, above a gate. This means that the area closest to the gate may be emptied, but the material forms a self-supporting arch above the gate, making unloading difficult.

[0008] To mitigate these problems, a common practice is to use steep sidewalls with vibrators attached. This arrangement reduces the risk of bulk cargo getting stuck during unloading. However, other drawbacks often arise when using this method.

[0009] Figure 1 A partial perspective cross-sectional view of a vessel according to the prior art is schematically shown. The vessel, depicted mainly in dashed lines, has a deadweight tonnage of approximately 8,600 tons and a gross vehicle capacity of approximately 11,300 cubic meters. More specifically, Figure 1 The cargo port of a bulk loader equipped with a self-unloading system is shown. From Figure 1 As can be seen, the steep sidewalls of the cargo opening prevent valuable interior space from being used for cargo storage on the sides and midships. Furthermore, to avoid wasting too much space, the vessel is equipped with two sets of parallel gates, one on the starboard side and one on the port side. The use of parallel gate sets necessitates the use of multiple conveyors beneath the gates. The use of multiple parallel conveyors necessitates the use of cross conveyors extending laterally along the vessel to feed bulk cargo to C-shaped conveyors used for lifting and transferring bulk cargo out of the vessel. Using multiple conveyors is both expensive and increases the number of moving parts, thus increasing maintenance, failure risks, and costly downtime. Furthermore… Figure 1 The vibrator is attached to the steep sidewalls of the vessel. This arrangement of the vibrator leads to undesirable body or structural noise and premature material fatigue. The vibrator can generate centripetal forces up to 300 kN, most of which are absorbed by the sidewalls and supporting structures.

[0010] Similar or identical problems arise when using land-based self-unloading systems with steep sidewalls and vibrators, as well as hopper systems using steep sidewalls and vibrators.

[0011] US2010 / 0272543 A1 recommends using less steep sidewalls combined with an array of individual surface segments incorporating vibrating elements. Each individual surface segment is supported by a dedicated support structure to form a funnel-shaped structure sloping towards the outlet. Therefore, the described system offers greater load capacity. However, the described system is very complex and expensive to construct. Furthermore, due to the vibrating elements, the described system still causes undesirable body or structural noise and premature material fatigue. By fixing the vibrating elements to the support structure, the ability of the vibrating elements to propagate vibrations to, for example, bulk materials is significantly impeded, thus reducing the effectiveness of the vibrating elements.

[0012] US 4,907,721 discloses a bulk silo for grains and granular materials, the bulk silo comprising an inclined floor tilted toward a set of nozzles. The inclined floor includes a vibrator attached to the floor for vibrating the floor. Each nozzle is formed like a tunnel, allowing grain or granular material to flow through the nozzle to a chain conveyor. Furthermore, each nozzle uses a gate to control the flow of grain passing through it. However, such nozzles can be prone to clogging.

[0013] Therefore, an improved system for the storage and recycling of bulk materials is needed. Invention Overview

[0015] In view of the above, one object of the present invention is to provide an improved system for the storage and recycling of bulk materials, the use of the system, and ships, land-based storage facilities and hoppers including the system.

[0016] Another objective is to provide a storage and recycling system for bulk materials that occupies less space.

[0017] Another objective is to provide a storage and recycling system for bulk materials that simplifies unloading from storage and recycling systems.

[0018] Another objective is to provide a storage and recycling system for bulk materials that allows for the handling of bulk materials with high internal friction.

[0019] Another objective is to provide a storage and recycling system for bulk materials that reduces the main noise level.

[0020] Another objective is to provide a storage and recycling system for bulk materials that reduces material fatigue in the system and surrounding components.

[0021] Another objective is to provide a storage and recycling system for bulk materials that reduces the number of auxiliary components used when unloading bulk cargo from the storage and recycling system.

[0022] To achieve the foregoing objectives and at least one of other objectives that are obvious from the following description, according to the concept of the present application, a storage and recycling system for bulk materials having the features defined herein is provided. According to the present application, a vessel including a storage and recycling system for bulk materials is provided. According to the present application, a land-based storage unit including a storage and recycling system for bulk materials is provided. According to the present application, a hopper including a storage and recycling system for bulk materials is provided. According to the present application, uses for the storage and recycling system are provided. Preferred variations of the inventive concept are readily apparent from this application.

[0023] More specifically, according to a first aspect, a system for storing and recycling bulk materials is provided, the system comprising: a bulk material holding space having a bottom portion provided with a discharge port, wherein the bottom portion includes an inclined support plate for supporting the bulk material and for assisting gravity-induced feeding of the bulk material toward the discharge port; a support structure supporting the support plate; and one or more vibrators connected to the support plate and configured to transmit vibrational energy to the support plate to induce vibrational movement of the support plate, wherein the support plate is inclined at an angle in the range of 15 degrees to 25 degrees relative to a horizontal plane. The support plate is supported by a support structure in a free-floating manner. The discharge port includes one or more inclined discharge port plates for guiding bulk material and assisting in gravity-induced feeding of the bulk material toward the discharge port. Each discharge port plate is inclined at an angle ranging from 30 to 70 degrees relative to the horizontal plane. One or more vibrators are connected to each discharge port plate and configured to transmit vibrational energy to the discharge port plate to induce vibrational movement. Each discharge port plate is supported by the support structure in a free-floating manner.

[0024] Therefore, an improved system for storing and recycling bulk materials is provided.

[0025] This storage and recycling system is designed for general bulk materials and is therefore suitable for general bulk materials.

[0026] Furthermore, the advantage of this storage and recycling system lies in its design to handle bulk materials exhibiting high internal friction (also known as high internal adhesion). Therefore, the system is designed to efficiently handle bulk materials that are prone to adhesion and clogging during processes such as unloading. Non-limiting examples of such bulk materials are wood chips and sawdust, which are prone to arching and forming walls during handling.

[0027] "Arching" refers to the ability of bulk materials to form a self-supporting arch that passes through the void space. This means that bulk materials can, for example, arch above the discharge port, such that the arch prevents the bulk materials from reaching the discharge port.

[0028] "Wall formation" refers to the formation of a self-supporting, steep wall by bulk materials. This means that bulk materials can form wall-like structures that prevent the material from flowing toward, for example, a discharge port. For instance, sawdust can form walls with more or less vertical surfaces, and their height can exceed 10 meters.

[0029] The storage and recycling system includes bulk material holding spaces. Bulk material holding spaces are typically designed to hold bulk cargo during transport, storage, and / or handling. Bulk cargo holding spaces can be, for example, cargo holds of ships or vessels, warehouses or storage facilities, hoppers, storage towers, railcars, or truck wreckage.

[0030] Therefore, bulk cargo can remain stationary in bulk material holding spaces for extended periods, such as when transported on ships or stored in storage facilities. Furthermore, bulk cargo can flow through bulk material holding spaces or remain stationary only for short periods, such as when handled in hoppers. Consequently, the size, shape, and design of bulk material holding spaces can vary considerably.

[0031] The bulk material holding space has a bottom section with a discharge port or gate. The discharge port is typically used to obtain bulk material from the bulk material holding space by opening the discharge port, allowing the bulk material to flow out or fall out of the bulk material holding space through the discharge port.

[0032] The bottom portion of the bulk material holding space includes an inclined support plate for supporting the bulk material and assisting in gravity-induced feeding of the bulk material toward the discharge port. Therefore, the bulk material can move along the inclined support plate toward the discharge port while being supported by it. The inclination of the inclined support plate causes gravity acting on the bulk material to assist in feeding it toward the discharge port.

[0033] The support plate is supported by a support structure. The support structure can be any structure capable of supporting the support plate. The support structure may include one or more plates supporting the support plate. The support structure may include one or more beams supporting the support plate. The support structure may include one or more grids supporting the support plate. The support structure may include a combination of one or more load-bearing structures, such as plates, beams, and grids.

[0034] One or more vibrators are connected to a support plate. The vibrators are configured to transfer vibrational energy to the support plate. Therefore, the vibrators induce vibrational movement of the support plate. This vibrational movement of the support plate propagates to the bulk material supported by the support plate. The vibrational movement propagating to the bulk material will thus vibrate or shake the bulk material or at least a portion of the bulk material. By vibrating the bulk material, arching and wall formation of the bulk material are prevented, thus making the bulk material less prone to adhesion and clogging. By vibrating the bulk material, the arching and wall formation of the bulk material can be caused to collapse, thereby preventing adhesion and clogging.

[0035] Any number of vibrators, including a single vibrator, can be advantageously used. The vibrator can be of any suitable type. The vibrator can be hydraulically driven. The vibrator can be pneumatically driven. The vibrator can be electrically driven. The vibrator can be electromagnetically driven. The vibrator can be adjustable. The vibration power of the vibrator can be adjusted. The vibration force of the vibrator can be adjusted. The amplitude of the vibrator can be adjusted. The vibration frequency of the vibrator can be adjusted. The vibration time of the vibrator can be adjusted, to give some non-limiting examples. The vibrator can be adjusted based on the current bulk material, thereby achieving efficient feeding of the bulk material toward the discharge port. For example, for materials with high internal friction, the vibration amplitude may need to be increased. Similarly, for materials with limited internal friction, the vibration amplitude may need to be decreased.

[0036] The support plate is tilted at an angle ranging from 15 to 25 degrees relative to the horizontal plane. This allows for an efficient storage and recycling system while using less space.

[0037] The support plate is supported by a support structure in a free-floating manner.

[0038] "Free-floating manner" means that the support plate is supported by the support structure such that the support plate can vibrate independently of the support structure, or substantially independently of the support structure. Therefore, the support plate is supported in a free or substantially free manner at its contact surface with the support structure. In other words, the support plate can rest freely against the support structure. The support plate can be restricted to movement within its plane relative to the support structure. This arrangement of the support plate ensures that at least its central main portion is not connected or linked to any other entity or object such as the support structure.

[0039] With this arrangement, the vibrator can effectively transfer vibrational energy to the support plate while limiting the amount of vibrational energy transferred to the support structure. Therefore, less vibration is transmitted to the surrounding environment, effectively reducing overall sound and premature material fatigue. Due to natural causes, a limited amount of vibrational energy transmitted by the vibrator can be transferred to the surrounding environment.

[0040] Because the support plates are supported in a free-floating manner, vibrational energy can be effectively transferred to the bulk cargo, even with a significantly increased amplitude. This results in more effective mitigation of arching and wall formation, and the bulk material can move more easily toward the discharge port. Furthermore, since the support plates are supported in a free-floating manner, materials with high internal friction cannot flow without the additional energy in the form of vibration, and such materials can be advantageously handled by the storage and recovery system. Therefore, the inclination of the support plates can be reduced, thus requiring less space for the storage and recovery system. As a result, more space can be provided for holding the bulk material without wasting too much space. Another consequence of the reduced inclination of the support plates is the reduction of arching of the bulk material.

[0041] The discharge port includes one or more inclined discharge port plates to guide the bulk material and assist in gravity-induced feeding of the bulk material toward the discharge port. Each discharge port plate is inclined at 30-70 degrees relative to the horizontal plane. This arrangement facilitates the discharge of bulk material through the discharge port. The combination of support plates and one or more inclined discharge port plates allows the bulk material to flow more easily through the discharge port. If the inclination of the support plates is less than that of one or more inclined discharge port plates, arching of the bulk material can be further prevented. Arching can be reduced because the support plates will exhibit a reduced ability to accept forces transverse to the horizontal plane. In other words, the support plates will not be as effective as when using steep sidewalls in supporting material arching.

[0042] One or more vibrators are connected to each discharge port plate. These vibrators are configured to transfer vibrational energy to the discharge port plates to induce vibrational movement. Each discharge port plate is supported by a support structure in a free-floating manner. This arrangement further facilitates the discharge of bulk material through the discharge ports.

[0043] Any number of vibrators, including a single vibrator, can be used advantageously. Refer above for details on how the vibrators and each discharge port plate are supported by the support structure in a free-floating manner.

[0044] The support structure may include a backplate, on which the support plate rests. This is advantageous because the support plate can be safely supported by the backplate. By supporting one plate on top of another, the contact surface between the two plates can be maximized. This reduces the risk of wear and / or deformation of the support plate due to vibration.

[0045] Each vibrator can be connected to the main surface of the bulk material holding space behind the support plate. This is advantageous because more than one vibrator or even just one vibrator can effectively transfer vibrational energy to the support plate to induce vibrational movement of the support plate without disturbing the bulk material holding space. Therefore, the vibrator does not occupy any space within the bulk material holding space. The vibrator also does not interfere with the flow of bulk material fed towards the discharge port of the bulk material holding space.

[0046] Each vibrator can extend through the opening in the support structure, which is advantageous because more than one vibrator or one vibrator can effectively transfer vibrational energy to the support plate to induce vibrational movement of the support plate with minimal impact on the support structure.

[0047] The system may also include clamping profiles for the periphery of the clamping support plate and the periphery of the support structure, which is advantageous because the support plate can be held in place relative to the support structure. Furthermore, the use of clamping profiles allows the support plate to move freely within the plane of the support plate. The use of clamping profiles allows the support plate to move freely within a limited range within the plane of the support plate. Additionally, the use of clamping profiles allows the support plate to be sealed relative to the support structure and / or any underlying structure, thereby preventing unintentional leakage of bulk material from the bulk material holding space.

[0048] The support plate can tilt at an angle ranging from 5 to 30 degrees relative to the horizontal plane. The support plate can tilt at an angle ranging from 17 to 23 degrees relative to the horizontal plane. The support plate can tilt at an angle of approximately 20 degrees relative to the horizontal plane.

[0049] The support plate can tilt at an angle ranging from 5 to 40 degrees relative to the horizontal plane. The support plate can tilt at an angle ranging from 5 to 50 degrees relative to the horizontal plane. The support plate can tilt at an angle ranging from 5 to 60 degrees relative to the horizontal plane. The support plate can tilt at an angle ranging from 20 to 30 degrees relative to the horizontal plane. The support plate can tilt at an angle of approximately 30 degrees relative to the horizontal plane.

[0050] The system may also include an intermediate layer disposed between the supporting structure and the support plate, the intermediate layer having sound attenuating properties, vibration isolation properties, and / or abrasion resistance properties. Several advantages can be obtained by arranging an intermediate layer between the supporting structure and the support plate. The intermediate layer can have sound attenuating properties, thereby reducing the overall sound level and / or mitigating the propagation of unwanted noise. The intermediate layer can have vibration isolation properties, thereby reducing the overall vibration level of the supporting structure and any entities connected to the supporting structure. Furthermore, the propagation of unwanted vibrations can be reduced. The intermediate layer between the supporting structure and the support plate can further reduce the overall sound. The intermediate layer between the supporting structure and the support plate can further reduce material fatigue. The intermediate layer can have abrasion resistance properties, thus reducing wear on the supporting structure and the support plate. Examples of suitable materials for the intermediate layer include rubber, natural rubber, synthetic rubber, polymers, PTFE, and steel-based energy-absorbing materials. The intermediate layer can include a variety of materials. The intermediate layer can include multiple layers disposed on top of each other. The multiple layers may or may not be connected to each other. The multiple layers can have different properties, including sound attenuating properties, vibration isolation properties, and abrasion resistance properties.

[0051] The system may also include additional inclined support plates for supporting bulk materials and for assisting in gravity-induced feeding of bulk materials from opposite sides of the system toward the discharge port, which is advantageous because the discharge port allows material to be fed from more than one direction.

[0052] The additional support plate may include one or more vibrators connected to the support plate and configured to transfer vibrational energy to the support plate to induce vibrational movement of the support plate, wherein the additional support plate is supported by a support structure in a free-floating manner. The advantages associated with the additional support plate are largely similar to those of the support plate itself, which is why the above description is provided.

[0053] Each vibrator can be independently controllable, which is advantageous because, if a discharge port plate and an additional support plate are present, the vibratory movement of the support plate can be controlled, enabling effective gravity-induced feeding of bulk material toward the discharge port. Therefore, if a discharge port plate and an additional support plate are present, vibratory movement may be induced in a certain area of ​​the support plate. Thus, the vibrators can be operated in a specific sequence to achieve effective feeding of bulk material toward the discharge port. Furthermore, the nature of the induced vibratory movement can be modified to suit different needs. For example, the amplitude, frequency, and operating time of each vibrator can be controlled independently. The fact that each vibrator can be independently controlled because it can operate only when needed also results in energy savings. The fact that each vibrator can be independently controlled because it can operate only at a specific power level also results in energy savings. The fact that each vibrator can be independently controlled because it can operate only when needed also results in the reduction of undesirable main body noise and / or vibration.

[0054] The system may also include a conveyor arranged below the bottom portion of the bulk material holding space for receiving bulk material from the bulk material holding space via a discharge port. Advantageously, the bulk material in the bulk material holding space can be transported away after leaving the bulk material holding space via the discharge port. The bulk material can be transported, for example, from a ship, storage facility, or warehouse.

[0055] According to another aspect of the invention, a vessel is provided that includes a storage and recovery system according to the first aspect. Generally, the features of this aspect provide similar advantages to those discussed above with respect to the first aspect. Therefore, to avoid undue repetition, these advantages will not be repeated.

[0056] According to another aspect of the invention, a land-based storage device is provided, comprising a storage and retrieval system according to the first aspect. Generally, the features of this aspect provide similar advantages to those discussed above with respect to the first aspect. Therefore, to avoid undue repetition, these advantages will not be repeated. However, it can also be mentioned that the land-based storage device according to the invention can have a significantly reduced height compared to prior art land-based storage devices. The reduced height, in turn, can lead to an increase in the overall capacity of the land-based storage device.

[0057] According to another aspect of the invention, a hopper is provided that includes a storage and recovery system according to the first aspect. Generally, the features of this aspect provide similar advantages to those discussed above with respect to the first aspect. Therefore, to avoid undue repetition, these advantages will not be repeated. However, it can also be mentioned that the hopper according to the invention can have a significantly reduced height compared to prior art hoppers. This reduced height can, in turn, lead to an increase in the overall capacity of a loading system, for example, including a gripper attached to a crane, since the crane may not need to lift the gripper as high as when using prior art hoppers. Another advantage is that the hopper can have a lighter weight and can contain less material compared to prior art hoppers.

[0058] According to another aspect of the invention, a storage and recycling system based on the first aspect is provided for processing materials selected from the group consisting of: wood chips, wood pellets, sawdust, coal, ore, gypsum rock, vanadium oxide, alumina, cement, sand, gravel, crushed stone, salt, grain, and aggregates. Therefore, the storage and recycling system according to the first aspect can be used for a wide variety of materials. Generally, the features of this aspect provide similar advantages to those discussed above with respect to the first aspect. Therefore, to avoid undue repetition, these advantages will not be repeated. Brief description of the attached diagram

[0067] Detailed description

[0068] Referring to the accompanying drawings, which illustrate preferred variations of the inventive concept, the inventive concept will now be described more fully below. However, the inventive concept can be embodied in many different forms and should not be construed as limited to the variations set forth herein; rather, these variations are provided for thoroughness and completeness, and to fully communicate the scope of the inventive concept to those skilled in the art. Throughout this specification, the same reference numerals refer to the same elements.

[0069] First, refer to Figures 2-4 A storage and recycling system 100 is described. The storage and recycling system 100 is described in the context of being installed in a vessel 200. However, the storage and recycling system 100 can be used in many different applications and application areas. References will follow. Figure 5 and Figure 6 Examples are described. However, these examples are considered non-limiting, meaning that the storage and recycling system 100 can be used just as well in, for example, warehouses, storage towers, train cars, truck debris sections, or the like.

[0070] exist Figure 2 The vessel 200 described herein, shown primarily in dashed lines, is a large marine vessel 200 in the form of a bulk loader with a deadweight tonnage of approximately 8,600 tons and a gross vehicle capacity of approximately 12,500 cubic meters. Therefore, the vessel 200 is designed to transport bulk materials 102 in its material holding space 104, commonly referred to as cargo hatches or cargo holds. The material holding space 104 may be segmented and thus comprises several parts that together form the material holding space 104.

[0071] The vessel 200 is a so-called self-unloading type, which means that bulk materials 102 can be automatically unloaded from the material holding space 104 by means of a self-unloading system 202 installed in the vessel 200.

[0072] The self-unloading system 202 includes, among other things, a storage and recycling system 100.

[0073] The described self-unloading system 202 is a permanently installed system, which is installed on the ship 200 at the dock during the construction of the ship 200. However, according to the concept of the invention, existing ships can be advantageously converted to have a self-unloading system including the storage and recovery system 100. Similarly, the storage and recovery system 100 according to the concept of the invention can be advantageously adapted for other applications and application areas.

[0074] Bulk material 102 present in the material holding space 104 can be automatically unloaded from the material holding space 104 through multiple discharge ports 106 provided at the bottom of the material holding space 104. In other words, the bottom portion 108 of the material holding space 104 is provided with discharge ports 106. Discharge ports 106 are commonly referred to as gates. The number of discharge ports 106 can vary greatly, for example, depending on the size of the current vessel 200. Dozens or even hundreds of discharge ports 106 can be advantageously used. A single discharge port 106 can be advantageously used, for example, in small vessels, hoppers, or storage towers.

[0075] The discharge ports 106 of the described vessel 200 are arranged along the longitudinal direction of the vessel 200. The discharge ports 106 of the described vessel 200 are arranged along the centerline of the vessel 200. Each discharge port 106 can be opened and closed individually. Multiple discharge ports 106 can be opened and closed simultaneously. However, when unloading bulk material 102 from the material holding space 104, it is generally practiced to open one discharge port 106 at a time.

[0076] As depicted, each discharge port 106 can be located above the conveyor 110. Therefore, the conveyor 110 is arranged below the bottom portion 108 of the bulk material holding space 104 to receive bulk material 102 from the bulk material holding space 104 via the discharge port 106.

[0077] At the forward end of vessel 200, conveyor 110 curves upward in a C-shape, at which point it engages with and is supported by lifting conveyor 111. Thus, bulk material 102 traveling on conveyor 110 is compressed and held between conveyor 110 and lifting conveyor 111 upon reaching the forward end of vessel 200, causing the bulk material to be lifted upward along the C-shape and further away from vessel 200. Approximately 500 cubic meters of cargo can be unloaded from vessel 200 via conveyor 110 and lifting conveyor 111. Conveyor 110 may terminate, for example, at another conveyor arranged above the deck of vessel 200. Conveyor 110 may terminate, for example, at a transport arm arranged above the deck of vessel 200. Conveyor 110 may terminate, for example, at a transport screw arranged above the deck of vessel 200.

[0078] When the discharge port 106 is opened, the bulk material 102 may fall onto the conveyor 110 and travel along the conveyor 110 until it is lifted up by the conveyor 110 and the hoisting conveyor 111 and leaves the ship 200. In order to control the amount of bulk material 102 on the conveyor and avoid excessive accumulation of bulk material 102 at any point on the conveyor 110, a discharge port 106 is advantageously opened in a timely manner.

[0079] As in Figure 3 As can be seen, the bottom portion 108 of the described bulk material holding space 104 uses multiple modules, each module forming part of the storage and recycling system 100, which in turn forms part of the self-unloading system 202. Figure 3 Each module of the type described herein includes opposing material support surfaces in the form of a support plate 112.

[0080] exist Figure 4 The text describes a side of the module, for example, the starboard side. Therefore, the described... Figure 4 The arrangement corresponds to a portion of the storage and recovery system 100 of the self-unloading system 202. However, according to the concept of the present invention, the described... Figure 4 The arrangement can effectively form a complete storage and recycling system 100. Therefore, Figure 4 The arrangement described herein will be referred to as storage and recycling system 100 below, although the arrangement forms part of the overall storage and recycling system 100 of the described vessel 200.

[0081] Therefore, in Figure 4 A storage and recovery system 100 for bulk material 102 is shown. The system 100 includes a bulk material holding space 104 having a bottom portion 108 as described above. The bottom portion 108 is provided with a discharge port 106. Furthermore, the bottom portion 108 includes an inclined support plate 112. Therefore, the support plate 112 supports the bulk material 102 within the bulk material holding space 104. Besides supporting the bulk material 102, the inclined support plate 112 has another primary purpose: to assist in gravity-induced feeding of the bulk material 102 toward the discharge port 106. Thus, under the influence of gravity, the bulk material 102 can flow or travel along the inclined support plate 112 toward the discharge port 106. The support plate 112 in the described system 100 is a steel plate with a thickness of 10 mm. Other thicknesses of the support plate 112 can also be advantageously used. For example, the thickness of the support plate 112 can typically be in the range of 2 mm to 20 mm. For example, the thickness of the support plate 112 can advantageously be in the range of 6 mm to 12 mm. Other materials such as aluminum and / or fiber-reinforced polymers can be advantageously used in the support plate 112. The support plate 112 can comprise a variety of materials.

[0082] The support plate 112 is supported by the support structure 114. The primary purpose of the support structure 114 is to bear and support the weight of the bulk material 102 present in the material holding space 104. The support structure 114 can be designed in different ways to achieve this purpose. The support structure 114 can advantageously include a metal plate. The support structure 114 can advantageously include a metal beam. The support structure 114 can advantageously include a metal grid. The support structure 114 can advantageously be made of other suitable materials, such as fiber-reinforced polymer materials.

[0083] exist Figures 2-4 In the described storage and recovery system 100, four vibrators 116 are connected to a support plate 112. Therefore, the vibrators 116 are configured to transfer vibrational energy to the support plate 112 to induce vibrational movement of the support plate 112. Thus, once one or more vibrators 116 are activated, the support plate 112 will begin to vibrate. The vibrators 116 can be, for example, hydraulic vibrators, pneumatic vibrators, electric vibrators, and / or electromagnetic vibrators. Different types of vibrators 116 are advantageously used. Different types of vibrators 116 can be advantageously combined. The vibrators 116 can operate according to different operating principles. Examples of suitable operating principles include counter-rotating unbalanced motors, dual unbalanced exciter gears, linear vibration, and triaxial unbalanced exciter designs. The vibrators 116 can operate according to different vibrational motions. Examples of suitable vibrational motions include linear motion, circular motion, and elliptical motion. The speed and stroke of the vibrators 116 can be adjusted. The speed and stroke of the vibrators 116 can be adjusted individually. The speed and stroke of the vibrator 116 can be adjusted according to the material properties of the current bulk material 102. Typical vibrational G-forces can be from 3G to 7G.

[0084] The support plate 112 is supported by the support structure 114 in a free-floating manner. Therefore, the vibrator 116 can transmit vibrational energy to the support plate 112 while affecting the support structure to a limited extent. In other words, the vibrator 116 can cause vibrational movement of the support plate 112 while only slightly affecting the support structure 114. The free-floating arrangement of the support plate 112 on the support structure 114 can thus significantly reduce the amount of vibration transmitted to the support structure 114. As a result of this vibration, the overall noise level in the ship 200 can be significantly reduced. As a further result, material fatigue and premature failure of the components of the ship 200, including the support structure 114, can be significantly reduced.

[0085] Furthermore, the induced vibrational movement of the support plate 112 can thus be transmitted to the bulk material 102 supported by the support plate 112. This induced vibrational movement of the support plate 112 can therefore prevent the bulk material 102 from arching and forming walls. Thus, such induced vibrational movement of the support plate 112 can disrupt the arches and / or walls formed in the bulk material 102. Therefore, such induced vibrational movement of the support plate 112 can also assist in the gravity-induced feeding of the bulk material 102 toward the discharge port 106.

[0086] As understood above, in addition to Figure 4 In addition to the support plate 112 described above, system 100 typically includes an additional inclined support plate 112 for supporting bulk material 102 and for assisting in gravity-induced feeding of bulk material 102 from opposite sides of the system toward discharge port 106. Also as understood above, the additional support plate 112 typically includes one or more vibrators 116 connected to it. Thus, the vibrators 116 are configured to transmit vibrational energy to the additional support plate 112 accordingly to induce vibratory movement of the additional support plate 112. Also as understood above, the additional support plate 112 is typically supported in a free-floating manner by support structure 114.

[0087] The described support structure 114 includes a back plate 118. A support plate 112 rests on the back plate 118. The back plate 118 in the described system 100 is a steel plate with a thickness of 10 mm. Other thicknesses of the back plate 118 can also be advantageously used. For example, the thickness of the back plate 118 can typically be in the range of 8 mm to 20 mm. Other materials such as aluminum and / or fiber-reinforced polymers can be advantageously used in the back plate 118. The back plate 118 can comprise a variety of materials.

[0088] In other variations, the support plate 112 may, for example, rest against a beam or against a grid.

[0089] Each of the four described vibrators 116 is connected to the main surface of the support plate 112 facing away from the bulk material holding space 104. In other words, all of the vibrators 116 are arranged on the underside of the support plate 112. To achieve this, each described vibrator 116 extends through an opening 117 in the support structure. This arrangement of the vibrators 116 places them all outside the bulk material holding space 104. Therefore, the presence of the vibrators 116 does not negatively affect how the bulk material 102 is fed toward the discharge port 106.

[0090] Each vibrator 116 can typically be connected to a bracket 119 extending through the opening 117. Each vibrator 116 can typically be connected to the bracket 119 by threading or welding. The bracket 119 can typically be connected to the support plate 112 by welding or threading.

[0091] In the described system 100, a clamping profile 120 is provided to clamp the peripheral portions of the support plate 112 and the peripheral portions of the support structure 114. Thus, the clamping profile 120 clamps the respective peripheral portions, such that the peripheral portions of the support plate 112 and the support structure 114 are held or pressed together. The described clamping profile 120 has a generally C-shape. For example, other shapes of the clamping profile 120 can be advantageously used depending on the current design or requirements. With this arrangement, the support plate 112 can be held in place relative to the support structure 114 while still allowing free movement within the plane of the support plate 112. More specifically, the support plate 112 has a limited range of free movement relative to the support structure 114 within the plane of the support plate 112. Furthermore, the use of the clamping profile 120 seals the support plate 112 relative to the support structure 114 and any underlying structure. This means preventing bulk material 102 from unintentionally leaving the bulk material holding space 104, which in turn means preventing bulk material 102 from entering between the support plate 112 and the support structure 114, which could otherwise have a negative impact on the system 100.

[0092] The clamping profile 120 may extend along one or more edges of the support plate 112. The clamping profile 120 may extend along all edges of the support plate 112. The clamping profile 120 may extend along portions of one or more edges of the support plate 112. In other words, the clamping profile 120 may be formed by multiple segments together forming the clamping profile 120. The clamping profile 120 may be positioned at the lowermost edge of the support plate 112 such that the support plate 112 is prevented or prevented from sliding downwards due to its tilt.

[0093] In the described system 100, the support plate 112 is inclined at an angle α of 20 degrees relative to the horizontal plane. Other angles α in the range of 5 to 30 degrees relative to the horizontal plane can also be used advantageously. By using an angle α of 20 degrees relative to the horizontal plane, a significant amount of valuable space can be saved. Therefore, the bulk material holding space 104 can be made larger compared to using steep sidewalls according to the prior art. For example, due to the free-floating arrangement of the support plate 112 and the vibrator 116 on the support plate 112, the support plate 112 can exhibit a significantly smaller angle α relative to the horizontal plane, while the bulk material 102 can still be fed toward the discharge port 106 in a gravity-assisted manner.

[0094] In the described system 100, an intermediate layer 122 is disposed between the support structure 114 and the support plate 112. Therefore, the intermediate layer 122 can be disposed between the support structure 114 and the support plate 112. The intermediate layer 122 in the described system 100 is a rubber sheet with a thickness of 10 mm. Other thicknesses of the intermediate layer 122 can be advantageously used. For example, the thickness of the intermediate layer 122 can typically be in the range of 2 mm to 50 mm.

[0095] Intermediate layer 122 can be used for a variety of purposes, including sound attenuation, vibration isolation, and abrasion protection. Other materials besides rubber can also be advantageously used in intermediate layer 122, such as polymers, PTFE, and steel-based energy-absorbing materials. Intermediate layer 122 may comprise multiple layers disposed on top of each other. System 100 may or may not include intermediate layer 122.

[0096] In the described system 100, the discharge port 106 further includes one or more inclined discharge port plates 124. Therefore, the discharge port plates 124 are arranged near the discharge port 106, and typically directly beside it. The discharge port plates 124 are used to guide the bulk material 102 and to assist in the gravity-induced feeding of the bulk material 102 toward the discharge port 106. For example, Figure 3 and Figure 4 As can be seen, the discharge port plate 124 is arranged at a steeper angle than the support plate 112. More specifically, each discharge port plate 124 is inclined at an angle ranging from 30 to 70 degrees relative to the horizontal plane. It should be noted that the discharge port plate 124 can be omitted, allowing bulk material to enter the discharge port directly from the support plate 112.

[0097] As in Figure 4 As can be seen, the described discharge port plate 124 is provided with two vibrators 116. Any number of vibrators 116 can be advantageously used on the discharge port plate 124. Thus, one or more vibrators 116 can be connected to each discharge port plate 124. The vibrators 116 are thus configured to transmit vibrational energy to the current discharge port plate 124 to induce vibrational movement of the discharge port plate 124. Furthermore, each discharge port plate 124 can be supported in a free-floating manner by the support structure 114. By supporting each discharge port plate 124 in a free-floating manner, the same or similar advantages as described with respect to the support plate 112 can be achieved. Therefore, those advantages will not be repeated here to avoid undue repetition.

[0098] The discharge port plate 124 may or may not be equipped with a vibrator 116. Some discharge port plates 124 may be equipped with a vibrator 116, while others may not.

[0099] The vibrator 116 of system 100 is advantageously independently controllable. Therefore, each vibrator 116 can be operated independently of any other vibrator in system 100. The operating parameters of each vibrator 116 can also be adjusted independently of any other vibrator in system 100. To give a few non-limiting examples, operating parameters may include the amount of vibration energy, frequency, operating time, and operating mode.

[0100] Several advantages can be achieved by using independently controllable vibrators 116. For example, the vibrators 116 can be controlled in a certain mode to achieve efficient feeding of the bulk material 102 toward the discharge port 106. A typical mode could be to first activate one or more vibrators 116 closest to the discharge port 106. The relevant vibrators 116 can be activated first after the spontaneous gravity-induced flow of the bulk material 102 has stopped in order to save energy and prevent induced vibration for an unnecessarily long period of time. Then, the vibrators 116 located further away from the discharge port can be activated sequentially to feed the bulk material 102 along the support plate 112 toward the discharge port 106 in an efficient manner.

[0101] The level of bulk material in the bulk material holding space 104 can be monitored. The vibrator 116 can be controlled based on the level of bulk material in the bulk material holding space 104. Adhesion or blockage of bulk material 102 in the bulk material holding space 104 can be monitored. The vibrator 116 can be controlled based on the adhesion or blockage of bulk material 102 in the bulk material holding space 104.

[0102] Now for reference Figure 5 This section conceptually describes a land-based storage unit 300 comprising a storage and recovery system 100 of the type described above. (As in...) Figure 5 As can be seen, the land-based storage unit 300 comprises multiple modules, each module including two opposing support plates 112 inclined toward a central discharge port 106. In the described land-based storage unit 300, multiple modules are arranged in three rows, one after the other. In other words, the storage and recovery system 100 comprises multiple modules, each module including a support plate 112 and a discharge port 106. Furthermore, the support plates 112 are equipped with vibrators 116 and are arranged in a free-floating manner supported on a support structure 114, as already referenced. Figures 2-4In more detail, conveyor 110 is arranged below the corresponding row of discharge port 106. Therefore, three conveyors 100 are used in the described land-based storage unit 300. It should be understood that when designing a land-based storage unit 300 including the storage and recycling system 100 of the type described above, any number of modules can be arranged in any number of rows. Therefore, any number of support plates 112, vibrators 116, conveyors 110, etc., can be advantageously used in the land-based storage unit 300. Therefore, the land-based storage unit 300 of the type described above is a self-unloading land-based storage unit 300.

[0103] Now for reference Figure 6 This section conceptually describes how hoppers 400 are used for unloading from ships. Each hopper 400 includes a storage and recovery system 100 of the type described above. Each hopper 400 includes two opposing support plates 112 inclined toward a centrally located discharge port 106. The support plates 112 are supported in a free-floating manner by support structures 114, as described above regarding... Figures 2-4 As described. Each support plate 112 is provided with two vibrators 116 of the type described above. In other words, a typical hopper 400 includes a bulk material storage space 104 that gradually narrows toward the discharge port 106.

[0104] When handling bulk material 102 on a ship, for example, using a grab bucket, the bulk material 102 can be temporarily stored in the hopper 400. Figure 6 As described, when unloading bulk cargo from a ship, the grab bucket can grab the bulk material from the ship's cargo hold and then lower the bulk material 102 into the hopper 400 located near the ship, for example... Figure 6 On the dock described in the text.

[0105] Alternatively, one or more hoppers of the type described above may be located above the deck of the vessel.

[0106] Conveyors, conveyor belts, conveyor screws, or the like used for transporting bulk cargo from ships may typically be arranged below each hopper 400. The conveyors, conveyor screws, or the like may be located at the ship's location. The conveyors or the like may be located at the dock or shipyard.

[0107] One or more grabs for unloading cargo holds of a vessel may be lifted by a crane located above the deck of the vessel itself. One or more grabs for unloading cargo holds of a vessel may be lifted by a crane located at a dock, dry dock, barge or similar facility.

[0108] Compared to existing hoppers, the hopper 400 of the described type can be made significantly lower and therefore lighter. For example, the weight of a hopper 400 with a bulk material handling capacity of 50 tons per run can be reduced from 90 tons to 30 tons. When the hopper is installed above the deck of the vessel itself, the reduction in height and weight of the hopper 400 compared to standard existing hoppers can reduce the vessel's rolling.

[0109] When the hopper 400 is used with large offshore vessels and large cranes, 40-50 tons of bulk material 102 can be lowered into the hopper 400 in a single grab. Therefore, the bulk material 102 can be stored in the hopper 400 temporarily or for an extended period. For example, even after 40-50 tons of bulk material 102 has been lowered into the hopper, the hopper can be emptied within approximately 30-40 seconds. In this case, the hopper can typically be emptied onto a conveyor, transport screw, or other transport device.

[0110] Furthermore, when, for example, hopper 400 is installed in a storage tower, bulk material 102 can be stored in hopper 400 for an extended period. As a few non-limiting examples, discharge port 106 can be located above a conveyor, transport screw, or cargo hold.

[0111] As described in detail above, the storage and recycling system 100 can be used for a wide variety of bulk materials. The storage and recycling system 100 can be used, for example, to process bulk materials 102 such as wood chips, wood pellets, sawdust, coal, ore, gypsum rock, vanadium, alumina, cement, sand, gravel, crushed stone, salt, grain, and aggregates.

[0112] It should be understood that the inventive concept is not limited to the variations and examples shown. Therefore, various modifications and variations are contemplated within the scope of the invention as defined by the appended claims.
