Description

Technical Field

[0001] This utility model relates to the technical field of port bulk material handling equipment, and more specifically, to a hopper. Background Technology

[0002] During the unloading process of existing bridge-type ship unloaders, when encountering materials with high viscosity and moisture content such as coal, these materials will gradually adhere to the inner wall of the large hopper. If the material is not cleaned in time and the material continues to be fed, the material will easily fill the large hopper or even block it. At this time, turning on the hopper wall vibration motor will only make the material in the lower part of the hopper more compacted, causing the material to be unable to fall to the ground conveyor belt. In this case, manual unblocking is required to allow the material to fall.

[0003] Existing methods for clearing blockages involve stopping the grab bucket unloading and manually cleaning the wet coal and other materials adhering to the hopper walls with shovels or other cleaning equipment. Then, the grid in the middle of the hopper is tapped to push any clumps of coal down, or the hopper is cleared by flushing it along the inner wall with a water hose. However, these methods are not only inefficient and wasteful of manpower and resources, but also pose numerous safety hazards during manual clearing, such as the risk of slipping and falling, threatening the safety of workers. Furthermore, flushing with water hoses increases the moisture content of the material, which may affect its quality and could cause a sudden accumulation of material that could trigger the emergency shutdown mechanism of the conveyor belt, directly harming the conveyor equipment and surrounding personnel. Utility Model Content

[0004] The problem this invention addresses is: how to design a hopper that can automatically clean materials with high viscosity and moisture content adhering to its inner wall, so as to avoid material accumulation and blockage in the hopper, while reducing the need for manual cleaning and related safety hazards, and improving the efficiency and reliability of the unloading process.

[0005] To address the aforementioned problems, this utility model provides a hopper, comprising: a hopper body, the hopper body including an upper hopper, a rotating hopper, and a lower hopper, the upper hopper, the rotating hopper, and the lower hopper all being inverted cone shapes, and the axes of the upper hopper, the rotating hopper, and the lower hopper coincide, the rotating hopper being disposed between the upper hopper and the lower hopper, the rotating hopper being configured to rotate relative to the upper hopper and the lower hopper along its axis, at least one scraper being connected to the inner wall of the rotating hopper, the scraper extending along the cone direction of the rotating hopper, with both ends of the scraper extending out of the rotating hopper and into the upper hopper and the lower hopper respectively, and a power mechanism being connected to the outer side of the rotating hopper, the power mechanism being used to drive the rotating hopper and the scraper to rotate relative to the upper hopper and the lower hopper.

[0006] Optionally, at least one bolt is connected to the scraper, one end of which passes through the rotating chamber and is connected to a locking nut.

[0007] Optionally, the two ends of the scraper have gaps between them and the inner peripheral walls of the upper chamber and the lower chamber, respectively.

[0008] Optionally, a first sealing ring is provided between the inner peripheral wall of the rotating chamber and the outer peripheral wall of the upper chamber.

[0009] Optionally, a second sealing ring is provided between the inner peripheral wall of the rotating chamber and the outer peripheral wall of the lower chamber.

[0010] Optionally, the outer peripheral wall of the rotating hopper is provided with a gear ring along the circumferential direction. The power mechanism includes a motor, a reducer and a drive gear. A support frame is connected to the outside of the hopper body. The motor and the reducer are both connected to the support frame. The output shaft of the motor is connected to the reducer. The drive gear is rotatably connected to the output end of the reducer. The drive gear meshes with the gear ring.

[0011] Optionally, a vision inspection device is provided at the upper end of the upper compartment body. The vision inspection device is connected to the support frame, and a controller is provided on the support frame. The vision inspection device and the motor are electrically connected to the controller.

[0012] Optionally, both the upper compartment and the lower compartment are connected to the support frame.

[0013] Optionally, the inner peripheral walls of the upper compartment, the rotating compartment, and the lower compartment are all provided with inner lining plates.

[0014] Optionally, the inner lining is made of stainless steel or polyethylene.

[0015] The beneficial effects of this utility model's hopper are as follows: The hopper body is divided into an upper hopper, a rotating hopper, and a lower hopper, all three parts being inverted cones with their axes coinciding, ensuring structural alignment and functional consistency. The rotating hopper is located between the upper and lower hoppers and can rotate relative to them along a common axis. At least one scraper is connected to the inner wall of the rotating hopper, extending along its generatrix. The scraper not only covers the inner wall of the rotating hopper but also extends into the upper and lower hoppers at both ends, allowing it to effectively scrape away material adhering to the inner walls of the hopper, whether it's the upper, rotating, or lower hopper, when the rotating hopper rotates. A power mechanism is connected to the outer side of the rotating hopper, providing the necessary power to rotate the rotating hopper and its scraper relative to the fixed upper and lower hoppers. In this way, the scraper can periodically scrape away accumulated material, preventing excessive accumulation or blockage of material on the inner wall of the hopper.

[0016] This invention's hopper achieves automated cleaning through mechanical means, avoiding the tediousness and danger of manual cleaning. The scraper, driven by the rotating chamber, automatically scrapes away material, improving cleaning efficiency and safety. Because the scraper covers the entire inner wall of the hopper, including the upper, rotating, and lower chambers, it effectively prevents material accumulation and blockage in these areas, ensuring smooth material flow. Automated cleaning reduces the need for manual intervention, lowers maintenance costs, and improves equipment reliability and stability. By reducing downtime due to material blockage, this hopper helps improve production efficiency, enabling more continuous equipment operation. It also avoids methods such as water flushing that could increase material moisture content and trigger emergency shutdown mechanisms, reducing adverse environmental and equipment impacts.

It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0023] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0024] like Figure 1 As shown in the figure, an embodiment of the present invention provides a hopper, comprising: a hopper body 1, the hopper body 1 including an upper hopper body 11, a rotating hopper body 12 and a lower hopper body 13, the upper hopper body 11, the rotating hopper body 12 and the lower hopper body 13 are all inverted cone shape, and the axes of the upper hopper body 11, the rotating hopper body 12 and the lower hopper body 13 coincide, the rotating hopper body 12 is disposed between the upper hopper body 11 and the lower hopper body 13, the rotating hopper body 12 is configured to rotate relative to the upper hopper body 11 and the lower hopper body 13 along the axis, at least one scraper 2 is connected to the inner wall of the rotating hopper body 12, the scraper 2 extends along the cone direction of the rotating hopper body 12, the two ends of the scraper 2 extend out of the rotating hopper body 12 and extend into the upper hopper body 11 and the lower hopper body 13 respectively, and a power mechanism 3 is connected to the outer side of the rotating hopper body 12, the power mechanism 3 is used to drive the rotating hopper body 12 and the scraper 2 to rotate relative to the upper hopper body 11 and the lower hopper body 13.

[0025] Specifically, the hopper body consists of three main parts: an upper hopper 11, a rotating hopper 12, and a lower hopper 13. All three are designed with an inverted conical structure and coincident axes to ensure that materials flow smoothly to the bottom of the hopper under gravity. The rotating hopper 12 is located between the upper hopper 11 and the lower hopper 13 and can rotate relative to both hoppers along its axis. At least one scraper 2 is installed on the inner wall of the rotating hopper 12. The scraper 2 extends along the conical direction of the rotating hopper 12, i.e., parallel to the generatrix of the inner wall of the rotating hopper 12, and extends at both ends into the upper hopper 11 and the lower hopper 13, respectively. When material is fed into the hopper, it begins to adhere to the inner wall of the hopper, especially materials with high moisture content and viscosity, such as wet coal. The power mechanism 3 is activated, driving the rotating chamber 12 to rotate. This causes the scraper 2 to move in a circular motion along the inner wall of the hopper. The scraper 2 is designed to scrape away the material adhering to the inner wall of the hopper and push it to the outlet of the lower chamber 13, thus preventing material accumulation and blockage. Because the scraper 2 extends into both the upper chamber 11 and the lower chamber 13, it ensures that the entire interior of the hopper is effectively cleaned.

[0026] In this embodiment, by setting up a rotating hopper 12 and a scraper 2, automatic cleaning of the inner wall of the hopper is achieved, avoiding the tediousness and danger of manual cleaning, improving cleaning efficiency, and reducing the risk of material accumulation and blockage. This reduces the need for manual hopper cleaning, thereby lowering the safety risks for operators, such as slipping and falling, and avoiding the problems of increased material moisture content and emergency shutdown of the conveyor belt caused by using water hoses for flushing. The hopper of this embodiment is suitable for materials of various moisture content and viscosity, especially easily adhered materials such as wet coal, improving the versatility and flexibility of the equipment, and adapting to the unloading needs of different scenarios and material types.

[0027] Optionally, such as Figure 1 As shown, at least one bolt 21 is connected to the scraper 2, and one end of the bolt 21 passes through the rotating chamber 12 and is connected to the locking nut 22.

[0028] Specifically, when installing the scraper 2, first pass the bolt 21 through the rotating hopper 12, and then fix the scraper 2 to the bolt 21. Next, tighten the bolt 21 with the lock nut 22 on the outside of the rotating hopper 12 to ensure that the scraper 2 is firmly installed on the inner wall of the rotating hopper 12. If it is necessary to adjust the position or angle of the scraper 2, it can be done by loosening the lock nut 22, moving the scraper 2 to the desired position, and then tightening the lock nut 22 again. Once the scraper 2 is firmly installed on the inner wall of the rotating hopper 12, when the rotating hopper 12 is driven by the power mechanism 3 to rotate, the scraper 2 will move in a circular motion along the inner wall of the hopper, scraping off the material attached to it, or agitating the material in the hopper body 1 to prevent the accumulation and blockage of the material.

[0029] In this optional embodiment, the scraper 2 is securely fixed to the inner wall of the rotating hopper 12 by bolts 21 and locking nuts 22, ensuring that it will not loosen or fall off during rotation. Simultaneously, the position and angle of the scraper 2 can be adjusted to adapt to different material types and unloading requirements. Bolts 21 and locking nuts 22 simplify the replacement and maintenance of the scraper 2; when the scraper 2 is worn or damaged, the locking nuts 22 can be easily loosened to remove and replace the scraper 2. By ensuring that the scraper 2 is securely fixed to the inner wall of the rotating hopper 12, the risk of damage due to loosening or falling off during rotation is reduced, contributing to improved durability of the scraper 2 and the entire hopper.

[0030] Optionally, such as Figure 1 As shown, the two ends of the scraper 2 have gaps between them and the inner peripheral walls of the upper chamber 11 and the lower chamber 13, respectively.

[0031] Specifically, a certain gap is maintained between both ends of the scraper 2 (i.e., the top and bottom of the scraper 2) and the inner peripheral walls of the upper hopper 11 and the lower hopper 13. The gap exists to avoid direct and continuous friction between the scraper 2 and the inner peripheral wall of the hopper during rotation. The main function of the scraper 2 is to scrape off the material adhering to the inner wall of the hopper, and the gap ensures that the scraper 2 will not damage the inner wall of the hopper or the scraper 2 itself due to excessive friction while scraping off the material. When the rotating hopper 12 rotates under the drive of the power mechanism 3, the scraper 2 rotates together. The cutting edge of the scraper 2 contacts the material on the inner wall of the hopper body 1, scrapes it off, and pushes it to the outlet position of the lower hopper 13. Due to the existence of the gap, the scraper 2 will not have direct and tight contact with the inner peripheral wall of the hopper during rotation, thereby reducing friction and wear.

[0032] In this optional embodiment, the clearance significantly reduces friction between the scraper 2 and the inner wall of the hopper, thereby extending the service life of both the scraper 2 and the hopper. This not only reduces maintenance costs but also improves the overall performance and reliability of the equipment. The appropriate clearance ensures that the scraper 2 can more effectively scrape off material adhering to the inner wall of the hopper. The scraper 2 is not hindered by friction during rotation, allowing for smoother material scraping and pushing to the outlet position of the lower hopper 13. The clearance allows the scraper 2 to adapt to hopper inner walls of different shapes and sizes, increasing its versatility and flexibility, enabling its application in a wider range of scenarios and material types. Reducing direct contact and friction between the scraper 2 and the inner wall of the hopper also reduces noise and vibration during equipment operation, improving equipment comfort and helping to reduce the risk of equipment failure and damage.

[0033] Optionally, such as Figure 1As shown, a first sealing ring 14 is provided between the inner peripheral wall of the rotating chamber 12 and the outer peripheral wall of the upper chamber 11.

[0034] Specifically, the rotating hopper 12 is located on the outside of the upper hopper 11 and the lower hopper 13. During rotation, the rotating hopper 12 must ensure that the internal material does not leak into the external environment. A first sealing ring 14 is positioned between the inner peripheral wall of the rotating hopper 12 and the outer peripheral wall of the upper hopper 11, forming a tight sealing interface. The first sealing ring 14 is typically made of an elastic material, such as rubber, silicone, or polyurethane, which possesses good elasticity and wear resistance. When the rotating hopper 12 rotates relative to the upper hopper 11, the first sealing ring 14 can tightly adhere to the contact surface of the two components, thereby preventing material leakage. The elasticity of the sealing ring can also adapt to minute gaps or deformations between the two components, ensuring a long-term stable sealing effect. During the operation of the hopper unloading device, the rotating hopper 12 continuously rotates under the drive of the power mechanism 3, and the first sealing ring 14 always maintains a tight contact state, effectively preventing material leakage regardless of the position of the rotating hopper 12.

[0035] In this optional embodiment, the first sealing ring 14 significantly improves the sealing performance between the rotating chamber 12 and the upper chamber 11, thereby effectively preventing material leakage. This not only reduces material waste and environmental pollution but also ensures the cleanliness and hygiene of the equipment. A stable sealing effect helps extend the service life of the equipment, reduces downtime and malfunctions caused by material leakage, improves the overall reliability and stability of the equipment, and lowers maintenance costs. The first sealing ring 14 is typically made of an elastic material, capable of adapting to sealing requirements under different temperature and pressure conditions, enabling the hopper unloading device to operate stably under a wider range of operating conditions, thus improving its adaptability and flexibility. Since the first sealing ring 14 is generally simple and easy to replace, equipment maintenance is also simplified. When the sealing ring is worn or damaged, a new sealing ring can be quickly replaced to ensure the continuous and stable operation of the equipment.

[0036] Optionally, such as Figure 1 As shown, a second sealing ring 15 is provided between the inner peripheral wall of the rotating chamber 12 and the outer peripheral wall of the lower chamber 13.

[0037] Specifically, the second sealing ring 15 is disposed between the inner peripheral wall of the rotating chamber 12 and the outer peripheral wall of the lower chamber 13, similar to the arrangement of the first sealing ring 14 between the rotating chamber 12 and the upper chamber 11 mentioned above, but in a different position, aiming to ensure the sealing between the rotating chamber 12 and the lower chamber 13. The second sealing ring 15 is also made of an elastic material, such as rubber, silicone, or other highly elastic polymers. When the rotating chamber 12 rotates relative to the lower chamber 13, the second sealing ring 15 can fit tightly against the contact surface of the two components, forming a continuous, leak-free sealing interface, ensuring that even when the rotating chamber 12 rotates at high speed or is subjected to large pressure, the material will not leak out from the gap between the rotating chamber 12 and the lower chamber 13. During the operation of the hopper unloading device, the rotating chamber 12 continues to rotate, while the second sealing ring 15 maintains a tight contact state, ensuring that the material is effectively confined within the rotating chamber 12 during the unloading process, thereby improving unloading efficiency and accuracy.

[0038] In this optional embodiment, the second sealing ring 15 significantly improves the sealing performance between the rotating chamber 12 and the lower chamber 13, which helps to prevent material from leaking from the gap between the rotating chamber 12 and the lower chamber 13 during the unloading process, thereby reducing material waste and environmental pollution.

[0039] Optionally, such as Figure 1 , Figure 2 As shown, a gear ring 121 is provided on the outer peripheral wall of the rotating hopper 12 along the circumferential direction. The power mechanism 3 includes a motor 31, a reducer 32 and a drive gear 33. A support frame 4 is connected to the outer side of the hopper body 1. The motor 31 and the reducer 32 are both connected to the support frame 4. The output shaft of the motor 31 is connected to the reducer 32. The drive gear 33 is rotatably connected to the output end of the reducer 32. The drive gear 33 meshes with the gear ring 121.

[0040] Specifically, a gear ring 121 is provided circumferentially on the outer peripheral wall of the rotating hopper 12, enabling the rotating hopper 12 to receive power through gear transmission. The power mechanism 3 consists of a motor 31, a reducer 32, and a drive gear 33. These components work together to transmit the power of the motor 31 to the rotating hopper 12. A support frame 4 is connected to the outer side of the hopper body 1 to support and fix the motor 31, reducer 32, and other components, ensuring the stability and reliability of the entire power mechanism 3. When the motor 31 starts, its output shaft begins to rotate, transmitting power to the reducer 32 connected to it. The reducer 32, through the reduction action of its internal gears, converts the high-speed rotation of the motor 31 into a low-speed, high-torque output to meet the rotational requirements of the rotating hopper 12. The output end of the reducer 32 is connected to the drive gear 33, which rotates with the output shaft of the reducer 32. The drive gear 33 meshes with the gear ring 121 on the rotating chamber 12. When the drive gear 33 rotates, it drives the gear ring 121 and the entire rotating chamber 12 to rotate together. As the rotating chamber 12 rotates, the scraper 2 contacts and moves relative to the inner wall of the rotating chamber 12. The scraper 2 scrapes the material off the chamber wall and pushes it toward the outlet during the rotation.

[0041] In this optional embodiment, the power mechanism 3, composed of a motor 31, a reducer 32, and a drive gear 33, achieves efficient and stable power transmission. The reducer 32 converts the high-speed rotation of the motor 31 into the low-speed, high-torque output required by the rotating hopper 12, improving unloading efficiency. The power mechanism 3 is connected to the outer support frame 4 of the hopper body 1, making the entire equipment structure compact and occupying a small area, which is beneficial for equipment installation and layout, especially in space-constrained working environments. The gear transmission method makes the rotation of the rotating hopper 12 smoother and vibration-free, which not only improves the operational stability of the equipment but also reduces noise and wear caused by vibration. The main components of the power mechanism 3 (motor 31, reducer 32, drive gear 33) are all connected to the support frame 4, facilitating daily maintenance and inspection. When these components need to be replaced or repaired, they can be easily disassembled and reinstalled, reducing maintenance costs and time. The power mechanism 3 in this embodiment can be adjusted and optimized according to different unloading requirements and working conditions. For example, the rotation speed and torque output of the rotating chamber 12 can be changed by replacing different models of motor 31 and reducer 32 to adapt to the requirements of different materials and unloading speeds.

[0042] Optionally, such as Figure 1 As shown, a vision inspection device 41 is provided at the upper end of the upper compartment 11. The vision inspection device 41 is connected to the support frame 4. A controller is provided on the support frame 4. The vision inspection device 41 and the motor 31 are electrically connected to the controller.

[0043] Specifically, a vision inspection device 41 is added to the upper end of the upper hopper 11. The vision inspection device 41 typically includes components such as a camera, image processor, and sensors, used to monitor and record the material status inside the upper hopper 11 or on the rotating hopper 12 in real time. A controller is also installed on the support frame 4, serving as the central hub of the entire system. This controller receives signals from the vision inspection device 41, processes data, and issues commands to actuators such as the motor 31. The coordinated operation between the vision inspection device 41 and the motor 31 is achieved through the controller. Based on the feedback signals from the vision inspection device 41, the controller adjusts the operating state of the motor 31 in real time to ensure that the material inside the rotating hopper 12 is unloaded in a predetermined manner and at a predetermined speed.

[0044] In this optional embodiment, the introduction of the vision inspection device 41 makes the unloading process more intelligent and precise. By monitoring the status and position of the material in real time, the controller can precisely control the operating status of the motor 31, thereby achieving precise unloading control and reducing material waste and errors. The combination of the vision inspection device 41 and the controller makes the entire hopper unloading device more automated and intelligent. Without manual intervention, the equipment can automatically adjust the unloading method and speed according to the actual situation of the material, improving work efficiency and safety.

[0045] Optionally, such as Figure 1 As shown, both the upper compartment 11 and the lower compartment 13 are connected to the support frame 4.

[0046] Specifically, the support frame 4, as the skeleton of the entire hopper, supports and fixes all components. The connection between the upper hopper 11 and the support frame 4 may involve the bottom or side wall of the upper hopper 11, ensuring its stable fixation to the support frame 4 and preventing it from shaking or tilting during unloading. The connection between the lower hopper 13 and the support frame 4 may involve the bottom or side wall of the lower hopper 13, or indirectly through the connection between the rotating hopper 12 and the lower hopper 13, ensuring the stability of the lower hopper 13 during unloading and allowing the rotating hopper 12 to rotate relative to the lower hopper 13. By connecting both the upper hopper 11 and the lower hopper 13 to the support frame 4, a stable overall structure is formed, capable of withstanding various forces during unloading, such as the weight of the material and the centrifugal force of the rotating hopper 12, ensuring the normal operation and safety of the equipment.

[0047] In this optional embodiment, connecting both the upper hopper 11 and the lower hopper 13 to the support frame 4 significantly improves the stability of the entire hopper, ensuring the accuracy and safety of the unloading process. Connecting the upper hopper 11 and the lower hopper 13 to the support frame 4 forms a more robust structural system capable of withstanding greater forces and pressures, extending the equipment's service life. Connecting all components to the support frame 4 simplifies the equipment installation process. Furthermore, it allows for easier disassembly and reinstallation of components when maintenance or repair is required.

[0048] Optionally, the inner peripheral walls of the upper compartment 11, the rotating compartment 12, and the lower compartment 13 are all provided with inner lining plates.

[0049] Specifically, the inner walls of the upper hopper 11, rotating hopper 12, and lower hopper 13 are all fitted with inner lining plates. These lining plates are typically made of wear-resistant and corrosion-resistant materials, such as stainless steel, alloy steel, or polymer materials, to protect the hopper body from damage caused by material friction and corrosion. The lining plates are tightly attached to the inner walls of the hopper body using bolts 21, welding, or other fixing methods, forming a continuous, smooth inner surface. When materials flow within the hopper, they come into direct contact with the lining plates, rather than the hopper body material, significantly reducing wear and corrosion and extending the hopper's service life. The smooth surface of the lining plates also facilitates smooth material flow, reducing material accumulation and blockage within the hopper body, and improving unloading efficiency. Because the lining plates are installed independently of the hopper body, they can be easily removed and replaced when severely worn or corroded, without requiring repair or replacement of the entire hopper body. This greatly reduces equipment maintenance costs and downtime.

[0050] In this optional embodiment, by providing inner lining plates on the inner peripheral walls of the upper chamber 11, the rotating chamber 12, and the lower chamber 13, the main body of the chamber can be effectively protected from friction and corrosion damage caused by materials, thereby extending the service life of the chamber. The smooth surface of the inner lining plate facilitates the smooth flow of materials, reducing material accumulation and blockage within the chamber. This not only improves unloading efficiency but also reduces equipment failures and downtime caused by material blockage.

[0051] Alternatively, the inner lining may be made of stainless steel or polyethylene.

[0052] Specifically, stainless steel is a high-strength, corrosion-resistant alloy steel with excellent wear resistance, impact resistance, and high-temperature resistance. Stainless steel linings effectively resist material friction, corrosion, and high-temperature effects, maintaining the smoothness and flatness of the silo's inner wall, which facilitates smooth material flow. Polyethylene is a lightweight, high-toughness thermoplastic with good wear resistance, chemical corrosion resistance, and impact resistance. Polyethylene linings reduce the overall weight of the equipment and have good sliding and self-lubricating properties, helping to reduce material adhesion and blockage within the silo. Regardless of whether stainless steel or polyethylene is used, the linings are tightly fitted to the inner wall of the silo using appropriate fixing methods (such as bolted connections, welding, or bonding), ensuring that the linings will not fall off or loosen during equipment operation, thus guaranteeing the stability and safety of the equipment. Stainless steel linings are suitable for handling materials with high hardness and strong abrasion, such as ores and coal. Their high strength and wear resistance ensure that the silo maintains good shape and dimensional stability during long-term operation. Polyethylene liners are more suitable for handling corrosive materials or for applications where it is necessary to reduce the weight of equipment. Their excellent chemical resistance and lightweight properties make the equipment more durable and easier to move.

[0053] In this optional embodiment, the inner liner made of stainless steel or polyethylene effectively resists material friction and corrosion, extending the service life of the silo. The smooth surface of the liner facilitates smooth material flow, reducing material accumulation and blockage within the silo, and improving unloading efficiency. As a consumable part, the liner can be easily replaced when damaged without replacing the entire silo, thus reducing equipment maintenance costs. The choice between stainless steel and polyethylene allows the liner to adapt to different material characteristics and working environments, improving the equipment's versatility and flexibility.

[0054] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
