Description

Technical Field

[0001] The present application relates to the technical field of port equipment, and in particular to a ship unloader. Background Art

[0002] As an important energy supply facility, the normal operation of thermal power plants depends on two key materials: coal and limestone. Coal is the main fuel for power generation, while limestone is used in the desulfurization process to reduce sulfide emissions generated during coal combustion and meet environmental protection requirements. The effective supply of these two materials is crucial to the stable operation of thermal power plants. However, due to the design and functional limitations of ship unloaders, the current ship unloaders in thermal power plants are mainly used for unloading coal, while limestone cannot share the existing coal unloading equipment due to its material characteristics.

[0003] Due to the differences in material properties of limestone and coal, they need to be transported and unloaded separately. Coal can be unloaded directly to the ship unloader of the thermal power plant by water transportation, while limestone usually needs to be transported by land truck due to its fragile and dusty characteristics. This separate transportation method not only increases logistics costs, but also reduces the efficiency of material supply. Compared with water transportation, land transportation is more expensive, and it is more difficult to control the dust problem of limestone during transportation, posing a potential threat to the environment and human health. Therefore, the existing ship unloader technology and transportation methods have obvious limitations when handling the two key materials required by thermal power plants. Summary of the invention

[0004] The purpose of this application is to provide a ship unloader that has the function of unloading coal and limestone. While reducing the material management cost and transportation cost of thermal power plants, it effectively controls the dust problem during limestone unloading and improves the efficiency and environmental protection of material handling.

[0025] The material recovery and blocking system comprises:

[0026] a material recovery cover plate, disposed between the first discharge hopper and the second discharge hopper, the material recovery cover plate being rotatable between 0° and 90°, and when the material recovery cover plate is at the 0° position, the material recovery cover plate at least partially covers the inlet of the first discharge hopper in a horizontal state, and when the material recovery cover plate is at the 90° position, the material recovery cover plate separates the inlet of the first discharge hopper from the inlet of the second discharge hopper in a vertical state;

[0027] A recovery drive member is connected to the material recovery cover plate, and the recovery drive member is used to adjust the rotation position of the material recovery cover plate.

[0028] In some embodiments, the second unloading system is further provided with a dust blocking device, the dust blocking device is located inside the second unloading hopper, and the dust blocking device includes:

[0030] An elastic mechanism connected to the grid plate, and the grid plate is kept in the second flipping position through the elastic action of the elastic mechanism;

[0031] When the limestone moves downward, the grid plate flips to the first flip position to allow the limestone to pass through, and the grid plate returns to the second flip position under the action of the elastic mechanism to block dust.

[0033] In some embodiments, the second unloading system is further provided with a double-opening rod valve and an arc valve, the double-opening rod valve is located at the connection between the second unloading hopper and the discharge cone hopper, and the arc valve is located at the connection between the discharge cone hopper and the loading system.

[0034] Compared with the above-mentioned background technology, the ship unloader provided in the present application mainly includes a first unloading system, a second unloading system and a dust collection system. The first unloading system is provided with a first unloading hopper for coal unloading; the second unloading system is provided with a second unloading hopper for limestone unloading; the dust collection system is connected to the second unloading system, and the dust collection system is used to suck the dust generated by the limestone unloading.

[0035] The limitations of the existing ship unloader technology and transportation methods mentioned in the background technology, especially when processing the two key materials of coal and limestone required for thermal power plants, are mainly manifested in two aspects: first, due to its material properties, limestone cannot share the same coal unloading equipment, resulting in the need for additional land road transportation, which increases logistics costs; second, the dust problem of limestone during land transportation is difficult to control, posing a potential threat to the environment and human health.

[0036] In response to these technical problems and defects, the technical solution of the ship unloader provided in this application realizes the joint unloading function of coal and limestone by integrating the first unloading system, the second unloading system and the dust collection system. The first unloading system is specially designed for unloading coal, while the second unloading system is specially designed for the characteristics of limestone to ensure that limestone can be unloaded from the ship safely and efficiently. This design allows thermal power plants to complete the unloading of two materials on the same equipment without the need for additional equipment or land transportation, thereby reducing the material management cost and transportation cost of thermal power plants.

[0037] In addition, the dust collection system is designed specifically to address the dust problem generated during limestone unloading. By connecting to the second unloading system, the dust collection system can effectively extract and treat dust, reduce environmental pollution, and improve the safety of the working environment. This is crucial to improving the working environment, protecting the health of workers, and reducing the impact on the surrounding environment.

[0038] In the ship unloader provided by the present application, the unloading process of coal and limestone is carried out separately, each independently but completed on the same equipment, so as to improve efficiency and reduce costs. At the beginning of the coal unloading process, the coal on the ship is unloaded through the first unloading system, the coal is unloaded through the first unloading hopper, and then sent to the fuel yard through the ground belt conveyor system of the dock.

[0039] At the beginning of the limestone unloading process, the limestone is unloaded through the second unloading hopper. Since the physical properties of limestone are different from those of coal, especially the problem of dust generation, this is specially considered in the design of the second unloading system. A second unloading system independent of the first unloading system is used to unload the limestone. During this period, the dust collection system is connected to the second unloading system, which is responsible for sucking the dust generated during the limestone unloading process to prevent the dust from spreading into the air. This system ensures the environmental friendliness of the limestone unloading process while protecting the health and safety of the staff. The limestone is directly loaded onto the truck after unloading, avoiding the additional cost and environmental impact of land transportation and improving the overall efficiency of material handling.

[0040] Combined with the above structure and process description, it can be seen that the ship unloader has at least the following beneficial effects: the ship unloader has the function of unloading both coal and limestone, which effectively controls the dust problem during limestone unloading while reducing the material management cost and transportation cost of the thermal power plant, thereby improving the efficiency and environmental protection of material handling.

[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0056] Please refer to Figure 1 , Figure 1 A schematic diagram of a ship unloader provided in an embodiment of the present application.

[0057] In the first specific embodiment, the ship unloader provided in the implementation scheme of the present application mainly includes a first unloading system 1, a second unloading system 2 and a dust collection system 3. The first unloading system 1 is provided with a first unloading hopper 11 for coal unloading; the second unloading system 2 is provided with a second unloading hopper 21 for limestone unloading; the dust collection system 3 is connected to the second unloading system 2, and the dust collection system 3 is used to suck the dust generated by the limestone unloading.

[0058] The limitations of the existing ship unloader technology and transportation methods mentioned in the background technology, especially when processing the two key materials of coal and limestone required for thermal power plants, are mainly manifested in two aspects: first, due to its material properties, limestone cannot share the same coal unloading equipment, resulting in the need for additional land road transportation, which increases logistics costs; second, the dust problem of limestone during land transportation is difficult to control, posing a potential threat to the environment and human health.

[0059] In view of these technical problems and defects, the technical solution of the ship unloader provided in this application realizes the joint unloading function of coal and limestone by integrating the first unloading system 1, the second unloading system 2 and the dust collection system 3. The first unloading system 1 is specially designed for unloading coal, while the second unloading system 2 is specially designed for the characteristics of limestone to ensure that limestone can be unloaded from the ship safely and efficiently. This design allows thermal power plants to complete the unloading of two materials on the same equipment without the need for additional equipment or land transportation, thereby reducing the material management cost and transportation cost of thermal power plants.

[0060] In addition, the design of the dust collection system 3 is specifically aimed at the dust problem generated during the limestone unloading process. By connecting with the second unloading system 2, the dust collection system 3 can effectively suck and treat the dust, reduce environmental pollution, and improve the safety of the working environment. This is crucial to improving the working environment, protecting the health of workers, and reducing the impact on the surrounding environment.

[0061] In the ship unloader provided by the present application, the unloading process of coal and limestone is carried out separately, each independently but completed on the same equipment, so as to improve efficiency and reduce costs. At the beginning of the coal unloading process, the coal on the ship is unloaded through the first unloading system 1, and the coal is unloaded through the first unloading hopper 11, and then sent to the fuel yard through the ground belt conveyor system of the dock.

[0062] At the beginning of the limestone unloading process, the limestone is unloaded through the second unloading hopper 21. Since the physical properties of limestone are different from those of coal, especially the problem of dust generation, this point is specially considered in the design of the second unloading system 2, and the second unloading system 2 independent of the first unloading system 1 is used to realize the unloading of limestone. During this period, the dust collection system 3 is connected to the second unloading system 2, which is specifically responsible for sucking the dust generated during the unloading process of limestone to prevent the dust from spreading into the air. This system ensures the environmental protection of the limestone unloading process, while also protecting the health and safety of the staff. After the limestone is unloaded, it is directly loaded onto the truck, avoiding the additional cost and environmental impact of land transportation, and improving the overall efficiency of material handling.

[0063] Combined with the above structure and process description, it can be seen that the ship unloader has at least the following beneficial effects: the ship unloader has the function of unloading both coal and limestone, which effectively controls the dust problem during limestone unloading while reducing the material management cost and transportation cost of the thermal power plant, thereby improving the efficiency and environmental protection of material handling.

[0064] Please refer to Figure 2 , Figure 2 for Figure 1 Schematic diagram of the mid-ship unloader omitting the support system and carrier.

[0065] In some embodiments, a dust collecting interface 22 is provided on the side of the second discharge hopper 21, and the dust collecting system 3 is connected to the dust collecting interface 22;

[0066] The dust collection system 3 includes:

[0067] The dust collecting pipeline 31 is connected to the dust collecting interface 22;

[0068] An air compressor 32 , an air storage tank 33 and a dust collector 34 are arranged in sequence along the dust collecting pipeline 31 .

[0069] In this embodiment, the second discharge hopper 21 is specifically used for the discharge of limestone, and a dust collection interface 22 is specially designed on its side, which is a key part for connecting the dust collection system 3. Through this interface 22, the dust collection system 3 can be effectively connected to the second discharge hopper 21, so as to directly extract and process the dust generated during the limestone discharge process.

[0070] The main components of the dust collection system 3 include a dust collection pipeline 31, which is an important passage connecting the dust collection interface 22 and subsequent dust collection equipment. The dust collection pipeline 31 ensures that the dust can be effectively transferred from the second discharge hopper 21 to the dust collection system for processing.

[0071] Arranged in sequence along the dust collecting pipeline 31 are an air compressor 32, an air tank 33 and a dust collector 34. The air compressor 32 is responsible for providing the necessary air pressure to push the dust to flow along the dust collecting pipeline 31. The air tank 33 is used to store the compressed air generated by the air compressor 32 to ensure the stable operation of the dust collecting system 3. The dust collector 34 is a device that finally captures and processes the dust, which can effectively reduce the impact of dust on the environment and protect the health of the workers.

[0072] Through such a configuration, the dust collection system 3 can efficiently handle the dust generated during limestone unloading, reduce environmental pollution, improve operation safety, and also reduce the additional environmental protection costs that may be caused by dust problems.

[0073] In some embodiments, the ship unloader further comprises:

[0074] The loading system 4 is provided with a first inlet 41 and a second inlet 42. The first inlet 41 is connected to the second unloading system 2, and the second inlet 42 is connected to the dust collecting system 3. The loading system 4 is used to load the collected limestone onto a truck.

[0075] In this embodiment, the design of the ship unloader further includes a loading system 4, which has two key connection points: a first inlet 41 and a second inlet 42. The first inlet 41 is directly connected to the second unloading system 2, which means that after the limestone is unloaded from the ship, it can directly enter the loading system 4 through this inlet to prepare for the loading process. The second inlet 42 is connected to the dust collection system 3, so that the material captured by the dust collection system during the limestone unloading process can also be redirected to the loading system 4.

[0076] The main function of the loading system 4 is to collect the limestone discharged by the second unloading system 2 and the limestone collected by the dust collecting system 3, and load them into the truck. This design enables the ship unloader to not only efficiently handle bulk materials, but also ensure the continuity and efficiency of the entire loading process, and reduce the loss of materials and environmental pollution during the transfer process.

[0077] Through this configuration, the loading system 4 optimizes the logistics management of the entire process of limestone unloading from ships to loading trucks, reduces operating costs, and improves the environmental standards of operations. This integrated design allows thermal power plants to manage their supply chain of key materials more flexibly and efficiently, while also reducing the impact on the environment.

[0078] In some embodiments, the loading system 4 includes:

[0079] A loading chute 43, used for collecting limestone and loading the collected limestone onto a truck;

[0080] The lifting mechanism 44 is connected to the loading chute 43 and is used to adjust the lifting position of the loading chute 43 relative to the carrier 01 to adapt to the changing surface height when the limestone is loaded.

[0081] In this embodiment, the loading system 4 is further refined into two main parts including a loading chute 43 and a lifting mechanism 44. The function of the loading chute 43 is to collect the limestone unloaded from the second unloading system 2 and guide the limestone to the loading point to achieve efficient loading. The design of the loading chute 43 allows the limestone to flow smoothly during the loading process, reduces the blockage or overflow that may occur during the loading process, and ensures the continuity and safety of the loading operation.

[0082] The lifting mechanism 44 connected to the loading chute 43 is responsible for adjusting the lifting position of the loading chute 43. This adjustment function is to adapt to the change in the height of the inner surface of the carrier 01 when the limestone is loaded, and ensure that the loading chute 43 always maintains an appropriate distance from the material surface in the carrier 01. The lifting mechanism 44 can automatically or manually adjust the position of the loading chute 43 according to real-time feedback, such as the loading height of the limestone, thereby improving the loading efficiency, reducing material waste, and ensuring the stability and safety of the loading process.

[0083] Through the precise control of the lifting mechanism 44, the loading chute 43 can flexibly adapt to the loading requirements of different vehicles 01, and can achieve efficient and precise loading operations for both large trucks and small vehicles. This design not only improves the flexibility and adaptability of loading operations, but also helps to reduce material losses and environmental pollution caused by improper loading, further improving the working efficiency and environmental performance of the entire ship unloader.

[0084] Please refer to Figure 3 and Figure 4 , Figure 3 for Figure 1 Schematic diagram of the mid-ship unloader omitting the first unloading system and the support system. Figure 4 for Figure 1 Side view of the second discharge hopper.

[0085] In some embodiments, the loading chute 43 includes:

[0086] The telescopic inner tube 431 is connected to the lifting mechanism 44. The telescopic inner tube 431 is used to move up and down under the drive of the lifting mechanism 44. The interior of the telescopic inner tube 431 is connected up and down. The telescopic inner tube 431 is connected to the first inlet 41.

[0087] The dustproof outer tube 432 is sleeved on the outside of the telescopic inner tube 431, the dustproof outer tube 432 is connected to the telescopic inner tube 431, the inside of the dustproof outer tube 432 is connected from top to bottom, and the channel between the dustproof outer tube 432 and the telescopic inner tube 431 is connected to the second inlet 42. When in use, the inside of the telescopic inner tube 431 and the channel between the dustproof outer tube 432 and the telescopic inner tube 431 simultaneously unload limestone to the carrier 01.

[0088] In this embodiment, the loading chute 43 is composed of two main parts: a telescopic inner tube 431 and a dustproof outer tube 432. The telescopic inner tube 431 is directly connected to the lifting mechanism 44 and is lifted and lowered by the lifting mechanism 44. This design enables the telescopic inner tube 431 to be vertically adjusted according to the change in the height of the limestone surface in the carrier 01, ensuring that the loading chute 43 always maintains an appropriate working distance from the material surface. The telescopic inner tube 431 is connected to the first inlet 41 and is responsible for transporting the limestone from the loading system 4 to the loading chute 43.

[0089] The dust-proof outer tube 432 is sleeved on the outside of the telescopic inner tube 431, connected to the telescopic inner tube 431, and forms a closed channel system. The function of the dust-proof outer tube 432 is to prevent dust from overflowing during the loading process and keep the loading environment clean. The channel between the dust-proof outer tube 432 and the telescopic inner tube 431 is connected to the second inlet 42, which means that the limestone collected by the dust collection system 3 can also be transported to the loading chute 43 through this channel, further enhancing the ability of the loading chute 43 to collect limestone.

[0090] Through this design, the loading chute 43 can not only effectively load limestone, but also control dust during the loading process, reduce environmental pollution, and improve the environmental friendliness of the loading operation. The coordinated use of the telescopic inner tube 431 and the dustproof outer tube 432 makes the loading chute 43 an efficient and environmentally friendly loading component, further improving the overall performance of the ship unloader and the safety of the operation.

[0091] Optionally, the dust collection system 3 also includes a discharge screw machine 35, which is located at the end of the dust collection pipeline 31. The outlet of the dust collector 34 is connected to the second inlet 42 of the loading system 4 through the discharge screw machine 35, that is, it is connected to the channel between the dust-proof outer tube 432 and the telescopic inner tube 431. The collected dust is sent into the channel between the dust-proof outer tube 432 and the telescopic inner tube 431 through the discharge screw machine 35.

[0092] In some embodiments, the lifting mechanism 44 includes:

[0093] A lifting device 441 is used to adjust the lifting position of the loading slide 43;

[0094] The detection device 442 is electrically connected to the lifting device 441, and is used to detect the surface height that changes when the limestone is loaded, so as to adjust the lifting position of the loading chute 43 according to the surface height that changes when the limestone is loaded.

[0095] In this embodiment, the lifting mechanism 44 is composed of two core components: a lifting device 441 and a detection device 442. The main function of the lifting device 441 is to adjust the lifting position of the loading chute 43 to adapt to the loading requirements of different vehicles 01 and the changing surface height of limestone during loading. By precisely controlling the lifting device 441, the loading chute 43 can be flexibly adjusted to the optimal working position to ensure the continuity and efficiency of the loading process.

[0096] The detection device 442 is connected to the lifting device 441 through an electrical signal and is responsible for real-time monitoring of changes in the material surface height during the limestone loading process. This real-time monitoring function enables the lifting mechanism 44 to dynamically adjust the position of the loading chute 43 according to the detected surface height data. The addition of the detection device 442 enables the lifting mechanism 44 to not only respond to the preset loading height, but also adapt to various changes that may occur during the loading process, such as changes in the limestone accumulation speed or irregularities in the space inside the carrier 01.

[0097] Through this intelligent design, the lifting mechanism 44 can ensure that the loading chute 43 always maintains the best working distance from the limestone surface, reducing the overflow or blockage problems that may occur during the loading process, while improving the safety and accuracy of the loading operation. This automated adjustment mechanism reduces the need for manual intervention, reduces the workload of operators, and improves the efficiency and reliability of the entire loading process.

[0098] As an option, the lifting device 441 uses a three-wire electric hoist to control the lifting and lowering movement of the telescopic inner tube 431. The telescopic inner tube 431 can be set to three sections connected in sequence, thereby extending the total length of the telescopic inner tube 431. The lifting device 441 drives the telescopic inner tube 431 with variable frequency, and is designed with a double closed-loop feedback of encoder speed and position. The lifting function has upper and lower limit control, which can accurately read the height of the telescopic inner tube 431 and realize automatic loading. The detection device 442 uses a radar, which senses the height of the material in the box of the carrier 01. The detection device 442 can also further use an alarm, which automatically rises the telescopic inner tube 431 with the height of the material. When it is detected that the material height is flush with the carrier 01, it automatically sounds the horn to lift the driver to drive the carrier 01 forward. The detection device 442 can also further control the arc valve 26. When it is detected that the carrier 01 is full, the arc valve 26 is automatically closed and the horn is automatically sounded to remind the driver that the carrier 01 is full.

[0099] In some embodiments, the ship unloader further comprises a support system 5 and a material recovery and blocking system 6, and the support system 5 is provided with a first unloading system 1, a second unloading system 2, a dust collection system 3 and a material recovery and blocking system 6;

[0100] The material recovery and blocking system 6 comprises:

[0101] The material recovery cover plate 61 is disposed between the first discharge hopper 11 and the second discharge hopper 21. The material recovery cover plate 61 can rotate between 0° and 90°. When the material recovery cover plate 61 is located at 0°, the material recovery cover plate 61 at least partially covers the inlet of the first discharge hopper 11 in a horizontal state. When the material recovery cover plate 61 is located at 90°, the material recovery cover plate 61 separates the inlet of the first discharge hopper 11 and the inlet of the second discharge hopper 21 in a vertical state.

[0102] The recovery driving member 62 is connected to the material recovery cover plate 61 , and the recovery driving member 62 is used to adjust the rotation position of the material recovery cover plate 61 .

[0103] In this embodiment, the design of the ship unloader is further extended to include a support system 5 and a material recovery and blocking system 6, which are essential for improving the efficiency and safety of the ship unloader. The support system 5, as the basic structure of the ship unloader, carries and connects the first unloading system 1, the second unloading system 2, the dust collection system 3 and the material recovery and blocking system 6, ensuring the stability and structural integrity of the ship unloader.

[0104] The design of the recovery and blocking system 6 aims to optimize the recovery of materials and prevent cross contamination between different materials. The material recovery cover 61 is a key component of the recovery and blocking system 6. It is arranged between the first discharge hopper 11 and the second discharge hopper 21 and can rotate between 0° and 90°. When the material recovery cover 61 is in the 0° position, that is, in a horizontal state, it can cover the inlet of the first discharge hopper 11 to prevent materials from entering by mistake. When the material recovery cover 61 is rotated to the 90° position, that is, in a vertical state, it can effectively separate the inlet of the first discharge hopper 11 and the second discharge hopper 21, ensuring that the two materials will not interfere with each other during the unloading process, and maintaining the orderly progress of the unloading operation.

[0105] The recovery drive 62 is a drive device connected to the material recovery cover 61, and is responsible for adjusting the rotation position of the material recovery cover 61. Through the operation of the recovery drive 62, the position of the material recovery cover 61 can be flexibly adjusted according to the actual needs of the ship unloading operation to adapt to different ship unloading scenarios. This design not only improves the operational flexibility of the ship unloader, but also enhances its adaptability to different operating conditions, ensuring the efficiency and safety of the ship unloading operation.

[0106] In some embodiments, the second unloading system 2 is further provided with a dust blocking device 23, which is located inside the second unloading hopper 21, and includes:

[0107] The grid plate 231 has a first flip position for allowing limestone to pass downward and a second flip position for blocking dust from surging upward;

[0108] The elastic mechanism 232 is connected to the grid plate 231, and the grid plate 231 is kept at the second flipping position by the elastic action of the elastic mechanism 232;

[0109] When the limestone moves downward, the grid plate 231 flips to the first flip position to allow the limestone to pass through, and the grid plate 231 returns to the second flip position under the action of the elastic mechanism 232 to block dust.

[0110] In this embodiment, the second unloading system 2 is specially equipped with a dust blocking device 23 to further control the dust problem during the limestone unloading process. The dust blocking device 23 is designed to be installed inside the second unloading hopper 21, and its main function is to reduce the flying of dust during the limestone unloading and keep the working environment clean and safe.

[0111] The core component of the dust blocking device 23 is the grid plate 231, which is a movable plate that can be flipped to two different positions as needed. In the first flip position, the grid plate 231 allows the limestone to be unloaded from the ship through the discharge hopper 21 smoothly; while in the second flip position, the grid plate 231 blocks the dust generated when the limestone is unloaded from surging upward, effectively reducing the spread of dust.

[0112] In order to realize the automatic flipping and positioning of the grid plate 231, the dust blocking device 23 also includes an elastic mechanism 232. The elastic mechanism 232 is connected to the grid plate 231, and uses its elastic effect to keep the grid plate 231 in the second flip position, that is, the position to block dust during the non-unloading period. When the limestone starts to move downward, the grid plate 231 flips to the first flip position under the action of gravity, allowing the limestone to pass smoothly. After the limestone passes, due to the elastic effect of the elastic mechanism 232, the grid plate 231 automatically returns to the second flip position, continues to block dust, and can also guide the dust formed by the material inside.

[0113] This design enables the dust blocking device 23 to automatically respond during the limestone unloading process, effectively controlling dust without affecting the normal unloading of the limestone. Such an automated design reduces manual intervention, improves the efficiency and safety of the unloading operation, and also protects the environment and the health of the workers.

[0114] In some embodiments, the second unloading system 2 is further provided with a discharge cone hopper 24, the inlet of the discharge cone hopper 24 is connected to the outlet of the second unloading hopper 21, and the outlet of the discharge cone hopper 24 is connected to the loading system 4, and the loading system 4 is used to load limestone.

[0115] In this embodiment, the second unloading system 2 adds a discharge cone hopper 24 to optimize the transfer process of limestone from the discharge hopper to the loading system. The discharge cone hopper 24 is designed to be directly connected to the outlet of the second unloading hopper 21, ensuring that the limestone can be smoothly transferred from the discharge hopper to the discharge cone hopper. Such a design reduces the blockage or overflow of limestone that may occur during the transfer process, and improves the unloading efficiency.

[0116] The other end of the discharge cone hopper 24 is connected to the loading system 4, and this connection ensures that the limestone can be effectively transported to the loading chute 43, thereby realizing the loading operation. By setting the discharge cone hopper 24, the flow path of the limestone is optimized, reducing the loss of materials and environmental pollution during the transfer process, and also reducing the workload of operators.

[0117] The use of the discharge cone hopper 24 not only improves the continuity and efficiency of the limestone loading operation, but also enhances the operational safety and environmental performance of the entire ship unloader. The addition of this component makes the function of the second unloading system 2 more complete, providing a more efficient and environmentally friendly limestone unloading and loading solution for thermal power plants.

[0118] In some embodiments, the second unloading system 2 is further provided with a double-opening rod valve 25 and an arc valve 26. The double-opening rod valve 25 is located at the connection point between the second unloading hopper 21 and the discharge cone hopper 24, and the arc valve 26 is located at the connection point between the discharge cone hopper 24 and the loading system 4.

[0119] In this embodiment, the design of the second unloading system 2 further includes a double-opening bar valve 25 and an arc valve 26. The arrangement of these two valves enhances the control capability of limestone flow. The double-opening bar valve 25 is installed at the connection between the second unloading hopper 21 and the discharge cone hopper 24. Its main function is to adjust the flow rate of limestone from the second unloading hopper 21 to the discharge cone hopper 24. This design allows the operator to adjust the flow rate of limestone as needed, optimize the unloading process, and prevent the accumulation or overflow of limestone.

[0120] The arc valve 26 is located at the connection point between the discharge cone hopper 24 and the loading system 4, and is mainly responsible for controlling the process of limestone flowing from the discharge cone hopper 24 into the loading system 4. The design of the arc valve 26 helps to reduce the dust spillage of limestone during loading, ensuring the cleanliness and safety of the loading operation. At the same time, the arc valve 26 can also quickly cut off the flow of limestone after loading is completed, thereby improving loading efficiency and reducing material loss.

[0121] The coordinated operation of these two valves enables the second unloading system 2 to more accurately control the unloading and loading process of limestone. The provision of the double-opening rod valve 25 and the arc valve 26 improves the operational flexibility and safety of the entire ship unloader, while also helping to reduce environmental pollution and improve operating efficiency. This design enables the second unloading system 2 to adapt to different operating conditions, ensuring efficient and environmentally friendly unloading and loading operations of limestone.

[0122] As an option, the double-open bar valve 25 is used to reduce the material bin pressure and control the flow rate of the material flow. According to the different characteristics of the material particle size, dust, etc., the double-open bar valve 25 can be adjusted to achieve the best dust collection effect. The arc valve 26 is controlled by air pressure, has a fast action speed, and is tightly closed to prevent the material from being scattered from the carrier 01 to the ground. According to the material flowability, the flow area is quickly contracted.
