Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and more specifically, to a conveying device and a molten salt production system. Background Technology

[0002] Conveying devices play a crucial role in the transportation of chemical raw materials. They not only ensure the efficient and safe transport of raw materials but also significantly improve production efficiency and reduce labor costs, thus having immeasurable value and significance for the smooth operation of the entire chemical industry chain. The importance of conveying devices is particularly pronounced when handling special raw materials such as anhydrous magnesium chloride molten salt, which is characterized by high temperature and strong corrosiveness, placing stringent requirements on its transportation methods. Traditionally, the transportation of such molten salts has relied on intermittent operations in the ladle-lifting workshop. While this method solves the basic transportation problem, it has significant drawbacks in practical applications. For example, frequent handling and unloading operations increase the labor intensity and safety risks for workers. Furthermore, the interruption of production continuity caused by intermittent transportation severely impacts production efficiency and economic benefits. Therefore, existing technologies propose a conveying device that achieves continuous transportation via pipelines.

[0003] However, existing conveying systems suffer from significant pipe expansion due to the high temperature of the molten salt during transport. Conversely, the pipes rapidly cool and contract as the molten salt cools. This repeated thermal expansion and contraction causes pipe deformation, which becomes increasingly pronounced with longer transport distances. While most existing conveying systems incorporate pipe support structures, these structures often struggle to cope with the complex deformations caused by temperature variations over long distances. Especially during continuous molten salt transport, the dynamic changes in the pipes demand high flexibility and adaptability from the support structure – a current technological weakness. This results in poor deformation adaptability during long-distance, high-temperature molten salt transport, increasing safety hazards during the process. Utility Model Content

[0004] The main purpose of this utility model is to provide a conveying device and a molten salt production system that can solve the problem of poor deformation adaptability of pipelines in the long-distance, high-temperature molten salt conveying of existing conveying devices.

[0005] To achieve the above objectives, according to one aspect of the present invention, a conveying device is provided, including a conveying pipe and a support assembly. The support assembly is disposed below the conveying pipe and supports the conveying pipe. When the conveying pipe deforms in the vertical direction, the support assembly can rise and fall in the vertical direction along with the deformation of the conveying pipe.

[0006] Furthermore, the support assembly includes a support section and an elastic element. The first end of the support section is connected to the conveying pipe, and the second end is connected to the first end of the elastic element. The second end of the elastic element is connected to the support surface. The support section can move up and down in the vertical direction as the conveying pipe deforms.

[0007] Furthermore, the support assembly includes a movable part disposed between the elastic member and the support surface. When the conveying pipe deforms in the horizontal direction, the movable part can move in the horizontal direction along with the conveying pipe.

[0008] Furthermore, the movable part includes a mounting base, an elastic element is disposed in the mounting base, one end of the elastic element is connected to the support section, and the other end is connected to the mounting base. The bottom of the mounting base is provided with rollers, and the mounting base can move relative to the support surface.

[0009] Furthermore, the conveying device includes a limiting part, which is disposed on the support surface. The limiting part includes a limiting plate, and two limiting plates are disposed opposite to each other on both sides of the moving part along the conveying direction of the conveying pipeline. The limiting plates can limit the movement of the moving part along the conveying direction.

[0010] Furthermore, the conveying pipeline includes inclined sections and bent sections. Support components are arranged below the inclined sections and support the inclined sections. Multiple inclined sections are connected by bent sections. The bent sections include connecting sections and vertical sections arranged at both ends of the connecting sections. The angle between the vertical sections and the connecting sections is 120° to 150°.

[0011] Furthermore, the conveying pipeline includes a main pipe and branch pipes, with multiple branch pipes connected in parallel and communicating with the main pipe. Both the main pipe and branch pipes slope downwards along the conveying direction of the conveying pipeline.

[0012] Furthermore, a heat tracing component is installed on the conveying pipeline, which can heat the material inside the conveying pipeline.

[0013] Furthermore, a metal mesh, an insulation layer, and a skin are arranged radially from the inside to the outside along the outer edge of the conveying pipe, and a heat tracing component is arranged between the metal mesh and the conveying pipe.

[0014] According to another aspect of the present invention, a molten salt production system is also provided, including a buffer tank and a conveying device. The buffer tank is equipped with a feeding pump, the feed end of the conveying device is connected to the feeding pump, and the discharge end of the conveying device is equipped with a collection tank. The conveying device is the aforementioned conveying device.

[0015] The present invention provides a conveying pipeline for transporting materials, particularly for the continuous transport of high-temperature or corrosive special materials. A support assembly is used to support the conveying pipeline. Because the conveying pipeline expands under the influence of high-temperature molten salt and contracts as the temperature decreases, this deformation caused by thermal expansion and contraction becomes increasingly significant with the increase in pipeline length. Therefore, the support assembly is designed to rise and fall with the vertical deformation of the conveying pipeline, allowing it to adapt to the pipeline's deformation. This ensures reliable support even when the long-distance conveying pipeline deforms due to temperature changes, greatly reducing the probability of failure caused by thermal stress deformation and guaranteeing the long-term stable operation of the conveying device.

Detailed Implementation

[0023] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] See also Figures 1 to 4As shown, this utility model provides a conveying device, which includes a conveying pipe 1 and a support assembly. The support assembly is disposed below the conveying pipe 1 and supports the conveying pipe 1. When the conveying pipe 1 deforms in the vertical direction, the support assembly can rise and fall in the vertical direction with the deformation of the conveying pipe 1.

[0025] In the above technical solution, the conveying pipeline 1 is used to transport materials, especially for the continuous transport of special materials that are high temperature or corrosive. The support assembly is used to support the conveying pipeline 1. Since the conveying pipeline 1 expands under the action of high-temperature molten salt and contracts when the temperature decreases, this deformation caused by thermal expansion and contraction becomes increasingly significant with the increase in the length of the conveying pipeline 1. Therefore, the support assembly is designed to rise and fall with the deformation of the conveying pipeline 1 in the vertical direction, allowing the support assembly to adapt to the deformation of the pipeline. This ensures reliable support even when the long-distance conveying pipeline deforms due to temperature changes, thereby greatly reducing the probability of failure caused by thermal stress deformation of the conveying pipeline and ensuring the long-term stable operation of the conveying device.

[0026] In one embodiment of the present invention, the support component includes a support section 21 and an elastic element 22. The first end of the support section 21 is connected to the conveying pipe 1, and the second end is connected to the first end of the elastic element 22. The second end of the elastic element 22 is connected to the support surface. The support section 21 can rise and fall vertically as the conveying pipe 1 deforms.

[0027] In the above technical solution, the support section 21 provides rigid support for the conveying pipeline 1, and the elastic element 22 connects the support section 21 to the support surface. Its elastic properties allow the support section 21 to move freely in the vertical direction while providing stable support force. When the conveying pipeline 1 is heated, it expands radially and deforms vertically. The combined use of the support section 21 and the elastic element 22 gives the support assembly vertical lifting capability, enabling it to adapt to the pipeline's vertical deformation and ensuring reliable support even when the long-distance conveying pipeline deforms due to temperature changes. The support surface typically refers to the ground or other fixed base surface, which is the foundation of the support assembly.

[0028] In one embodiment of the present invention, a connector is provided between the support segment 21 and the elastic member 22, and the support segment 21 is connected to the elastic member 22 through the connector.

[0029] In the above technical solution, the connector can be a connecting plate or a connecting column. By using a connecting plate or a connecting column, a reliable connection between the spring and the support section 21 can be achieved, ensuring that the support section 21 can smoothly transmit the vertical movement of the conveying pipe 1 to the spring. Under the elastic deformation characteristics of the spring, the support assembly is given the ability to lift in the vertical direction, so that the support section 21 can adapt to the deformation of the pipe in the vertical direction, ensuring that the long-distance conveying pipe can be reliably supported even when it deforms due to temperature changes.

[0030] In one embodiment of the present invention, the support component includes a movable part disposed between the elastic member 22 and the support surface. When the conveying pipe 1 deforms in the horizontal direction, the movable part can move in the horizontal direction along with the conveying pipe 1.

[0031] In the above technical solution, the conveying pipeline 1 will also deform along the pipeline conveying direction under the influence of temperature changes. The moving part is set between the elastic member 22 and the support surface and can move on the support surface. When the conveying pipeline 1 deforms in the horizontal direction due to thermal expansion and contraction, the moving part can adjust its own position with the lateral movement of the conveying pipeline 1, thereby avoiding the deformation of the pipeline in the horizontal direction being rigidly constrained and reducing the lateral stress caused by the expansion and contraction of the pipeline.

[0032] In one embodiment of the present invention, the movable part includes a mounting base 231, an elastic member 22 is disposed in the mounting base 231, one end of the elastic member 22 is connected to the support section 21, and the other end is connected to the mounting base 231. A roller 232 is provided at the bottom of the mounting base 231, and the mounting base 231 can move relative to the support surface.

[0033] In the above technical solution, the mounting base is the basic structure of the moving part, used to support the elastic element 22 and limit the support section 21, ensuring that the support section 21 can move together with the mounting base on the support surface. One end of the elastic element 22 is connected to the support section 21, and the other end is connected to the mounting base 231. On the one hand, it provides the support section 21 with vertical freedom, ensuring that the support section 21 can adapt to the deformation of the conveying pipe 1 in the vertical direction. On the other hand, it ensures that the elastic element 22 can move together with the mounting base on the support surface, ensuring that the support assembly can adapt to the deformation of the conveying pipe 1 in the horizontal direction. Rollers are set at the bottom of the mounting base 231, so that the mounting base and its connected elastic element 22 and support section 21 can move smoothly on the support surface. The roller design can reduce friction and make the movement of the moving part smoother, thereby ensuring that the support assembly can adapt to the deformation of the pipe in the horizontal direction without restricting or hindering the deformation of the conveying pipe 1.

[0034] In one embodiment of this utility model, the mounting base 231 is a box or sleeve, and the top of the mounting base 231 is provided with a through hole. The support section 21 passes through the through hole and is connected to the elastic member 22.

[0035] In the above technical solution, the through hole ensures that the support section 21 can pass through the mounting base 231 and connect with the elastic element 22. On the other hand, when the mounting base 231 moves along the support surface, the support section 21 contacts the inside of the through hole, so that the support section 21 can move together with the mounting base 231.

[0036] In one embodiment of the present invention, the conveying device includes a limiting part, which is disposed on the support surface. The limiting part includes a limiting plate 31. Two limiting plates 31 are disposed opposite to each other on both sides of the moving part along the conveying direction of the conveying pipe 1. The limiting plates 31 can limit the movement of the moving part along the conveying direction.

[0037] In the above technical solution, the limiting part is used to limit the movement range of the moving part. The limiting part includes a limiting plate 31. By fixing the limiting plate 31 to the support surface, a boundary is formed to limit the movement range of the moving part. If the movement range of the moving part is not limited, the moving part may exceed the safe range and collide with surrounding equipment or structures, or the moving part may move excessively under the action of external force, causing the support component or the conveying pipe 1 to fail. Since the main deformation of the conveying pipe 1 in the plane is along the conveying direction, by setting two limiting plates 31 opposite to each other on both sides of the moving part along the conveying direction of the conveying pipe 1, the movement of the moving part along the conveying direction is limited, reducing unnecessary limiting in other directions and reducing the complexity and processing cost of the device.

[0038] In one embodiment of the present invention, the conveying pipe 1 includes an inclined section 11 and a bent section 12. A support component is disposed below the inclined section 11 and supports the inclined section 11. Multiple inclined sections 11 are connected by the bent section 12. The bent section 12 includes a connecting section and vertical sections 13 disposed at both ends of the connecting section. The included angle between the vertical section 13 and the connecting section is 120° to 150°.

[0039] In the above technical solution, the inclined section 11 is designed to slope downwards along the conveying direction, which helps to promote the natural flow of molten salt by utilizing gravity and reducing resistance during the conveying process. The inclined section 11 has a simpler structure than the bent section 12; therefore, placing the support assembly below and supporting the inclined section 11 can significantly improve the reliability of the support assembly for the conveying pipeline 1. The bent section 12 is mainly used to adjust the vertical height of the conveying pipeline and to regulate the flow rate of the conveyed material, preventing the material from continuously accelerating downwards under gravity within the inclined section 11 and causing additional impact on the pipeline. The bent section 12 can bend in the conveying direction or to the side opposite to the conveying direction. Setting the bent section 12 to bend in a Z-shape to the side opposite to the conveying direction allows the conveying pipeline 1 to extend backwards when heated and expanded by heat at the bent section 12. This avoids the conveying pipeline 1 from only expanding along the conveying direction, resulting in insufficient expansion space and excessive stress, or even breakage. The connecting section works in conjunction with the vertical section 13 to achieve bending and turning of the conveying pipeline.

[0040] The angle between the vertical section 13 and the connecting section is designed to be between 120° and 150°. This angle range ensures a smooth transition of molten salt in the bending section 12, effectively reducing material flow rate and impact. At the same time, it ensures that the material can flow naturally along the slope under the action of gravity. In addition, the appropriate bending angle can also provide enough space to accommodate the thermal expansion of the conveying pipeline 1 and reduce the risk of pipeline rupture caused by thermal stress.

[0041] In one embodiment of the present invention, the conveying pipeline 1 includes a main pipe 14 and branch pipes 15. Multiple branch pipes 15 are arranged in parallel and connected to the main pipe 14. Both the main pipe 14 and the branch pipes 15 are inclined downward along the conveying direction of the conveying pipeline 1.

[0042] In the above technical solution, the main pipe 14 serves as the primary channel for molten salt transport, mainly connecting the feed pump 6 and the branch pipes 15 to form a material transport path. The branch pipes 15 are designed to connect in parallel to the main pipe 14, with each branch pipe capable of independently handling a portion of the transport task. The downward-sloping branch pipes 15 also utilize gravity to ensure smooth flow of molten salt within each branch pipe. This parallel arrangement increases system redundancy; even if individual branch pipes are temporarily unusable due to blockages or other abnormalities, the remaining branch pipes can still maintain a continuous supply of molten salt, improving the system's ability to respond to emergencies.

[0043] In one embodiment of this utility model, a heat tracing component 4 is provided on the conveying pipeline 1, which can heat the material inside the conveying pipeline 1.

[0044] In the above technical solution, the heat tracing assembly 4 typically includes electric heat tracing tape, steam heat tracing pipe, or hot oil heat tracing pipe, among which electric heat tracing tape is widely used in the continuous transportation of molten salt due to its convenience and precise temperature control capability. The heat tracing assembly 4 is directly wound or wrapped around the outer wall of the transportation pipeline 1, transferring heat to the molten salt inside the pipeline through heat conduction, heating the main pipe 14 and branch pipes 15 to the melting point of the molten salt, and keeping the transportation pipeline within the required temperature range of the molten salt to ensure the fluidity of the molten salt.

[0045] In one embodiment of this utility model, when the heat tracing assembly 4 uses an electric heat tracing cable, the electric heat tracing cable is spirally wound around the conveying pipe 1, or the electric heat tracing cable is continuously wrapped around the conveying pipe 1 in a U-shape.

[0046] In the above technical solution, the electric heating cable is spirally wound around the conveying pipe 1. This arrangement increases the contact area between the electric heating cable and the pipe surface, improves heat transfer efficiency, and ensures that the molten salt can be continuously and uniformly heated. The electric heating cable is wrapped in a continuous U-shape around the conveying pipe 1. Compared with the spiral winding method, the continuous U-shape reduces the overlap of the electric heating cable on the pipe, avoids local overheating, and provides sufficient coverage area to maintain the temperature of the molten salt.

[0047] In one embodiment of the present invention, a metal mesh 101, an insulation layer 102, and a skin 103 are arranged radially from the inside to the outside along the outer edge of the conveying pipe 1, and a heat tracing component 4 is arranged between the metal mesh 101 and the conveying pipe 1.

[0048] In the above technical solution, the metal mesh 101 is attached to the outer wall of the conveying pipe 1, providing a foundation for the support and positioning of the heat tracing assembly 4. The heat tracing assembly 4 is positioned between the metal mesh 101 and the conveying pipe 1, ensuring that the heat tracing assembly can be uniformly and tightly attached to the pipe, thereby improving heat transfer efficiency, ensuring uniform temperature of the molten salt, and avoiding local overheating or condensation. The metal mesh 101 can protect the conveying pipe 1 from minor external physical impacts and abrasions, protecting the internal insulation layer and the conveying pipe from direct damage, and extending the service life of the equipment.

[0049] The insulation layer 102 typically comprises insulation materials such as felt or aerogel. Under high-temperature transportation conditions, the insulation layer 102 can effectively slow down heat loss from the outer wall of the pipe, maintain the temperature of the molten salt inside the pipe, and prevent solidification and blockage due to temperature drop. By reducing heat loss, the insulation layer 102 indirectly reduces the energy consumption of the heat tracing components and improves the overall thermal energy utilization efficiency of the system.

[0050] The skin 103 is typically made of aluminum alloy and is located outside the insulation layer 102. As the outermost protective shell, it can withstand the influence of harsh external environments, such as weather changes and corrosive gases. At the same time, it seals the insulation layer 102 and the metal mesh 101 to prevent them from being directly damaged. In addition, the skin 103 has good waterproof and dustproof effects, protecting the internal structure from the erosion of moisture and dust, thereby maintaining the good appearance and structural stability of the entire conveying system.

[0051] In one embodiment of this utility model, the metal mesh 101 is an arc-shaped sheet, and multiple metal meshes 101 are arranged in a layered manner along the circumference and axial direction of the conveying pipe 1 to wrap the conveying pipe 1. Multiple clamps are provided along the circumference of the conveying pipe 1 to fix the metal mesh 101 on the conveying pipe 1.

[0052] In the above technical solution, the conveying pipe 1 is typically cylindrical. The arc-shaped sheet-like metal mesh 101 can better conform to the outer surface of the pipe. The pipe expands when heated, and the arc-shaped sheet-like metal mesh 101 is designed to account for thermal expansion, allowing for some axial and radial movement of the pipe, reducing mechanical stress caused by thermal expansion, and protecting the pipe from damage. The segmented design of the arc-shaped sheet-like metal mesh 101 makes installation and maintenance easier; the metal mesh can be replaced or repaired by removing the clamps without extensive disassembly of the entire conveying system.

[0053] In one embodiment of this utility model, the insulation layer 102 is an arc-shaped sheet, and multiple insulation layers 102 are stacked sequentially along the circumference and axial direction of the conveying pipe 1 to wrap the conveying pipe 1. Multiple clamps are provided along the circumference of the conveying pipe 1 to fix the insulation layer 102 to the conveying pipe 1.

[0054] In the above technical solution, the insulation layer 102 is designed as an arc-shaped sheet, which can tightly fit the outer surface of the conveying pipeline 1, reduce air gaps, improve thermal insulation performance, effectively reduce heat loss, and maintain the temperature stability of the molten salt inside the pipeline. The stacked arrangement of multiple insulation layers 102 provides adaptability to the pipeline when it is heated and expands, avoiding damage to the insulation layer due to pipeline expansion. At the same time, this design can ensure the structural integrity and insulation effect of the insulation layer during the thermal expansion and contraction of the pipeline. The arc-shaped sheet-like insulation layer 102 is easy to install in sections and can be fixed with clamps without complicated welding or pasting processes, reducing the difficulty and cost of installation and maintenance. When it is necessary to replace or repair the insulation layer, a single clamp can be removed and the insulation layer sheet underneath can be replaced without affecting the insulation layer structure of other parts.

[0055] According to another aspect of the present invention, a molten salt production system is also provided, including a buffer tank 5 and a conveying device. The buffer tank 5 is equipped with a feeding pump 6, the feed end of the conveying device is connected to the feeding pump 6, and the discharge end of the conveying device is equipped with a collection tank 7. The conveying device is the conveying device described in the above embodiment.

[0056] In the above technical solution, the buffer tank 5 serves as a temporary storage and preheating container for molten salt. Its function is to balance material supply and demand, providing a continuous and stable source of molten salt for the conveying device. It also preheats the molten salt, ensuring it reaches a suitable temperature before entering the conveying device, thus preventing changes in material properties due to temperature fluctuations. The feed pump 6 connects the buffer tank 5 to the feed end of the conveying device. Its main function is to pump the molten salt from the buffer tank 5 into the conveying device, while simultaneously controlling the flow rate and pressure of the molten salt by adjusting the pump speed, ensuring a smooth and efficient conveying process. The conveying device is the core of the molten salt production system. It consists of a main pipe 14, branch pipes 15, a heating assembly 4, and supporting components, responsible for conveying the molten salt from the buffer tank 5 to the collection tank 7. The inclined design and parallel branch pipe layout of the conveying device, combined with the heating of the electric heating tape, ensure the fluidity and temperature stability of the molten salt during the conveying process. The collection tank 7 is located at the discharge end of the conveying device, serving as the final receiving container for the molten salt. Its function is to collect the molten salt output by the conveying device, facilitating subsequent processing or storage.

[0057] This molten salt production system, by incorporating a conveying device with supporting components, enables the system to adapt to the deformation of pipelines caused by temperature changes when conveying high-temperature materials. This ensures reliable support even when long-distance pipelines deform, significantly reducing the probability of pipeline failures due to thermal stress deformation and guaranteeing the long-term stable operation of the molten salt production system.

[0058] In one embodiment of the present invention, the molten salt production system further includes a feed pipe 8, one end of which extends into the buffer tank 5, and the other end is connected to the feed end of the feed pump 6.

[0059] In the above technical solution, the suction pipe 8 is used to guide the material into the suction pump 6. The suction pipe 8 can extend to the bottom of the buffer tank 5 to ensure that the molten salt is drawn from the bottom of the tank, avoiding the inhalation of scum or incompletely melted solid particles from the material surface into the conveying pipeline, which would affect the normal operation of the system. The independent suction pipe 8 allows operators to easily inspect or clean the pipeline without operating the entire buffer tank 5, reducing maintenance workload and safety hazards during operation.

[0060] In one embodiment of this utility model, a flow regulating pump 9 is also provided on the conveying pipeline 1.

[0061] In the aforementioned technical solution, the flow regulating pump 9 can precisely adjust the conveying speed of molten salt according to production needs, which is crucial for ensuring the stability and efficiency of the production process. In a molten salt production system, excessively fast or slow flow rates can lead to a decline in system performance. For example, excessively fast flow rates may increase fluid resistance and pipe wear, while excessively slow flow rates will prolong the residence time of molten salt in the pipes, increasing the risk of cooling and solidification. The introduction of the flow regulating pump 9 enhances the overall adaptability of the system. It can cope with changes in the molten salt demand on the production line, ensuring that the optimal material flow rate is provided at different production stages, thereby maintaining the flexibility and efficiency of system operation.

[0062] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The conveying pipeline 1 is used to convey materials, especially for the continuous conveying of special materials that are high temperature or corrosive. The support assembly is used to support the conveying pipeline 1. Since the conveying pipeline 1 expands under the action of high-temperature molten salt and contracts when the temperature decreases, the deformation caused by this thermal expansion and contraction becomes increasingly significant as the length of the conveying pipeline 1 increases. Therefore, the support assembly is designed to rise and fall with the deformation of the conveying pipeline 1 in the vertical direction, so that the support assembly can adapt to the deformation of the pipeline and ensure reliable support even when the long-distance conveying pipeline deforms with temperature changes. This greatly reduces the probability of failure caused by thermal stress deformation of the conveying pipeline and ensures the long-term stable operation of the conveying device.
