[0003] Traditional molten salt recovery methods mostly use high-temperature molten salt directly injected into large static cooling tanks or molds, relying on natural convection or simple air cooling for heat dissipation. This method has a very slow cooling speed, and the molten salt is in a high-temperature liquid state for a long time, which not only leads to large equipment space occupation and long processing cycle, but also causes large temperature gradients and thermal stress in the molten salt, resulting in serious cracks or even explosion of the solidified salt block, affecting the efficiency and safety of subsequent mechanical crushing. In addition, the slow cooling process may allow some impurity components to have sufficient time to precipitate and enrich in the grain boundaries, affecting the purity of the recovered salt.

[0004] In addition, there is no industrialized method for crushing and collecting the solidified molten salt after cooling. Obviously, the existing static cooling method has poor compatibility with continuous molten salt discharge or upstream processes, which restricts the automation and scaling of the entire recovery process.

[0024] Example 1 Combined with appendix Figure 1 To be continued Figure 4 This embodiment proposes a molten salt condensation crushing and recovery device, including a cooling platform 1, a discharge pipeline 3, a recovery silo 4, a moving frame 5, a crushing roller 7, a scraper 8, and a circulating cooling section.

[0025] The cooling platform 1 is equipped with a liquid cooling channel 90 and a track. The output end of the discharge pipe 3 faces one end of the cooling platform 1. The top opening of the recovery hopper 4 is located below the other end of the cooling platform 1. A drive unit 6 is provided on the moving frame 5, which drives the moving frame 5 to move along the track. A crushing roller 7 is rotatably mounted on the moving frame 5, with a gap between the crushing roller 7 and the surface of the cooling platform 1. A scraper 8 is located at the bottom of the moving frame 5, on the side of the crushing roller 7 facing the discharge pipe 3. The circulating cooling unit is connected to the liquid cooling channel 90 and is used to transport the heat exchange medium to the liquid cooling channel 90 for recovery and cooling. A thermometer 2 is also included, pointing towards the surface of the cooling platform 1.

[0026] In the molten salt condensation, crushing, and recovery device of this embodiment, the circulating cooling section preferably includes a liquid tank 91, a pump body 92, and a radiator 93. The liquid tank 91 stores a liquid heat exchange medium. The liquid tank 91 is connected to the input end of the liquid cooling channel 90 through the pump body 92, and the output end of the liquid cooling channel 90 is connected to the input end of the liquid tank 91 through the radiator 93. Specifically, the heat exchange medium can be water. Relatively cool water is pumped from the liquid tank 91 into the liquid cooling channel 90 by the pump body 92 for the condensation of the liquid molten salt. Subsequently, the heated water in the liquid cooling channel 90 flows into the radiator 93 for heat dissipation and cooling, and then flows back into the liquid tank 91. The above process is repeated cyclically, thereby ensuring that a relatively cool heat exchange medium is always flowing in the cooling channel, thus achieving efficient condensation of the liquid molten salt.

[0027] As is conceivable, the radiator 93 can be integrated with or connected to a waste heat recovery unit, such as a high-temperature heat pump or a generator set. This unit uses the medium- and low-temperature thermal energy recovered from the molten salt and present in the heat exchange medium to generate electricity. The generated electricity can be used to power the drive unit 6 or other low-voltage electrical equipment (such as sensors and controllers) in the device of this embodiment. Thus, not only is the latent heat of solidification and sensible heat of the molten salt effectively utilized, reducing the net energy consumption of the entire recovery process and realizing the cascade utilization of energy, but the energy self-sufficiency rate and environmental benefits of the device are also improved.

[0028] Furthermore, in this embodiment, the cooling platform 1 also includes vertical baffles 13, which are fixedly disposed on both sides of the cooling platform 1. Thus, in this embodiment, due to the arrangement of the vertical baffles 13, the flowing molten salt can be prevented from overflowing to the outside of the cooling platform 1.

[0029] Furthermore, in this embodiment, the temperature probe of the thermometer 2 is preferably positioned vertically pointing towards the surface of the cooling platform 1, and the thermometer 2 is not located on the travel path of the moving frame 5, so as not to interfere with the moving frame 5. In this embodiment, the thermometer 2 can measure the temperature of the molten salt on the surface of the cooling platform 1. Multiple thermometers 2 can be arranged along the laying direction of the cooling platform 1 to comprehensively detect the temperature of the molten salt on the cooling platform 1.

[0030] The working process of the molten salt condensation, crushing, and recovery device in this embodiment includes: (1) material spreading and cooling; (2) crushing and scraping; and (3) return stroke. After the above three working processes are carried out in sequence, they can be repeated in a cycle, thereby realizing the continuous or semi-continuous automated cooling and recovery of liquid molten salt. The following is a description of the above three working processes.

[0031] Regarding the "material spreading and cooling" process: High-temperature liquid molten salt flows out through the discharge pipe 3, which is preferably centrally located directly above the starting end of the cooling platform 1. After flowing out, the molten salt forms a sheet-like fluid and flows naturally towards the other end of the cooling platform 1, eventually spreading evenly across the entire cooling platform 1 from the starting end and gradually cooling to form a thin layer. During the flow, the outflowing high-temperature liquid molten salt achieves initial cooling due to the gradually increasing heat dissipation area. Simultaneously, the presence of the liquid cooling channel 90 accelerates the removal of heat from the liquid molten salt, making the cooling process even faster. The heat exchange medium within the liquid cooling channel 90 circulates and cools through the aforementioned circulating cooling section.

[0032] To ensure a more uniform distribution of the molten salt and improve its cooling efficiency, the opening width of the drain pipe 3 should be compatible with the width of the cooling platform 1. Generally, the opening width of the drain pipe 3 needs to be slightly narrower than the width of the cooling platform 1. In a preferred embodiment, the ratio of the opening width of the drain pipe 3 to the width of the cooling platform 1 is 1:1.2 to 1:1.5. It is conceivable that if the edge of the opening of the drain pipe 3 is too close to the edge of the cooling platform 1, when the flow rate of the molten salt flowing out of the drain pipe 3 is high, the molten salt may splash outside the cooling platform 1. When the cooling platform 1 is equipped with vertical baffles 13, molten salt may also adhere to the vertical baffles 13 on both sides of the cooling platform 1. Therefore, this embodiment sets a lower limit value of 1:1.2. However, the opening width of the discharge pipe 3 should not be too narrow. It is necessary to ensure that the molten salt flows out and avoids accumulating in the center of the platform due to the narrow outlet, making it difficult to spread to both sides. Therefore, this embodiment sets an upper limit of 1:1.5. At this time, it can be ensured that the molten salt flowing out of the opening of the discharge pipe 3 has a sufficient flow rate, so that the molten salt can quickly cover most of the platform width.

[0033] In a preferred embodiment, the discharge pipe 3 includes a flat opening. Specifically, the discharge pipe 3 can be a reducing pipe that transitions from a circle to a flat rectangle, installed at the outlet of the molten salt pipe, so that the molten salt flows out as a flat, sheet-like flow. The width of the flat opening conforms to the preferred proportion of the aforementioned embodiment. This flattening design not only helps to improve the flow and coverage rate of the molten salt in the width direction of the cooling platform 1, but also, compared to a circular pipe, the flat opening structure can increase the instantaneous discharge area and flow velocity of the molten salt, thereby increasing the initial kinetic energy of the molten salt film. The relatively large initial kinetic energy helps to propel the molten salt film towards the far end of the cooling platform 1, effectively accelerating the spread speed of the molten salt across the entire cooling platform 1, eliminating the risk of molten salt accumulating at the initial end and insufficient coverage at the far end, and thus significantly improving the continuity and efficiency of the entire condensation and crushing process.

[0034] Regarding the "crushing and scraping" process: When thermometer 2 detects that the molten salt temperature is below a certain set temperature value below the solidification temperature, it indicates that the molten salt has fully solidified. Preferably, only one thermometer 2 is set, that is, only the local temperature on the cooling platform 1 near the recovery hopper 4 is detected. Taking this single thermometer 2 as an example, if the temperature is below the lower limit value, it indicates that even the molten salt in the far end area of ​​the cooling platform 1 that is the last to solidify has been fully cooled and solidified, and crushing can begin at this time.

[0035] Once the temperature reaches the target, the operation of the circulating cooling unit is simultaneously stopped, and the heat exchange medium in the liquid cooling channel 90 ceases circulation to achieve energy savings. Subsequently, the drive unit 6, typically a motor, is activated, rotating the wheels at the bottom of the moving frame 5 to move it along the track. The moving frame 5 moves from the side closest to the discharge pipe 3 towards the side where the recovery hopper 4 is located. During this movement, the crushing roller 7 contacts and rubs against the solidified molten salt, causing it to roll. This rolling action crushes the solidified molten salt flakes into particles. Simultaneously, the scraper 8, installed at the bottom of the moving frame 5 and located behind the crushing roller 7, scrapes up the crushed molten salt particles and pushes them along the surface of the cooling platform 1 until they fall into the recovery hopper 4.

[0036] Regarding the "return stroke", when the moving frame 5 travels to the end of the stroke of the cooling platform 1, the drive unit 6 reverses and drives the moving frame 5 back to the starting position, and then the next working cycle can begin, thereby realizing the continuous or semi-continuous automated cooling and recovery of liquid molten salt.

[0037] In a preferred embodiment, the cooling platform 1 includes a base plate 11 and a wear-resistant panel 12. A liquid cooling channel 90 is laid below the base plate 11, and the wear-resistant panel 12 is laid above the base plate 11. The wear-resistant panel 12 is preferably made of austenitic stainless steel. Austenitic stainless steel has excellent mechanical properties at high temperatures, a hardness far greater than molten salt particles, and excellent corrosion resistance to liquid molten salt. The wear-resistant panel 12 can be fixed to the base plate 11 by bolts or other means, and can be replaced individually after wear, simplifying maintenance and significantly extending the service life of the cooling platform 1.

[0038] In conjunction with the aforementioned embodiments, vertical baffles 13 are provided on both sides of the cooling platform 1. A transition surface can be provided between the vertical baffles 13 and the wear-resistant panel 12. The provision of the transition surface can prevent material residue and make it difficult for solidified molten salt to adhere to corners, facilitating cleaning. The transition surface is generally arc-shaped and can be achieved by providing rounded corners at the connection between the baffles and the wear-resistant panel 12.

[0039] In this embodiment, the crushing roller 7 is preferably mounted on the movable frame 5 via a bearing seat 500. The crushing roller 7 is a passive roller, which rolls by relying on the propulsion force of the movable frame 5 and the friction force with the solidified material, and crushes the solidified molten salt sheet on the cooling platform 1 by its own weight.

[0040] Preferably, the crushing roller 7 is densely covered with crushing teeth 70. These teeth 70 effectively break down solidified molten salt into molten salt particles. By selecting crushing teeth 70 with different densities, the size of the molten salt particles can be varied. Furthermore, there is a gap of 0.5-3 mm between the tip of the crushing teeth 70 and the cooling platform 1. This gap ensures that the crushing teeth 70 do not directly scrape or abrade the platform surface, effectively protecting the equipment, while simultaneously enabling effective crushing of solidified molten salt flakes of most thicknesses.

[0041] The crushing roller 7 is preferably mounted on the movable frame 5 via a bearing seat 500. In another preferred embodiment, the movable frame 5 is provided with a limiting groove 501, and the bearing seat 500 is movably engaged with the limiting groove 501. A first elastic element 502, which is a spring, is provided between the bottom surface of the bearing seat 500 and the limiting groove 501. In this embodiment, the bearing seat 500 and the first elastic element 502 constitute an elastic floating mechanism between the crushing roller 7 and the movable frame 5. This elastic floating mechanism allows the crushing roller 7 to have a certain elastic jumping space in the vertical direction. At the same time, the bearing seat 500 is placed in the slot of the movable frame 5, so that the crushing roller 7 can only move up and down relative to the movable frame 5, but can move horizontally with the movable frame 5. When encountering molten salt blocks that are not completely solidified or have uneven thickness, the crushing roller 7 can float upwards elastically, avoiding equipment jamming or bearing excessive impact loads, thus providing overload protection. Secondly, this floating design can automatically adapt to the slight unevenness of the surface of the cooling platform 1, ensuring the smooth operation of the crushing operation.

[0042] The device in this embodiment relies on scraper 8 to push the broken molten salt into the recovery hopper 4. In the preferred embodiment, as shown in the attached... Figure 2 As shown, the scraper 8 is inclined and hinged at one end to the movable frame 5. A second elastic element 503 is provided between the scraper 8 and the movable frame 5, and the second elastic element 503 is used to pull the scraper 8. The second elastic element 503 can be a spring. In this embodiment, the angle of the scraper 8 can be adjusted by selecting second elastic elements 503 of different lengths, thereby changing the gap height between the scraper 8 and the cooling platform 1 to adapt to different scraping requirements. Furthermore, the second elastic element 503 prevents excessive impact on the connection structure of the scraper 8 when it encounters molten salt powder, thus avoiding damage.

[0043] In actual operation, if the scraper 8 encounters molten salt powder and gets stuck, the lever principle may cause the entire moving frame 5 to lift. To solve this problem, upper and lower limit tracks can be used. The guide wheels at the bottom of the moving frame 5 can be constrained within the upper and lower limit tracks, thereby preventing the moving frame 5 from being lifted as a whole.

[0044] In other embodiments, a first baffle 101 is provided at one end of the cooling platform 1 near the drain pipe 3, and the side of the first baffle 101 facing away from the drain pipe 3 smoothly transitions to the surface of the cooling platform 1. (See attached diagram) Figure 3 As shown, the first baffle 101 can be a metal plate with a slope at one end, that is, a smooth transition between the slope and the surface of the cooling platform 1. The first baffle 101 can prevent liquid molten salt from overflowing from the end of the cooling platform 1 near the drain pipe 3, while the smooth transition can ensure that the molten salt flowing to that point can be naturally guided back to the cooling platform 1.

[0045] Furthermore, in another embodiment, a second slope 102 is fixedly provided on the surface of the cooling platform 1 near the end of the recycling hopper 4, and the side of the second slope 102 facing the discharge pipe 3 smoothly transitions with the surface of the cooling platform 1. (See attached diagram) Figure 4 As shown, the second slope 102 can also be a metal plate with a sloping end, that is, a smooth transition between the slope and the surface of the cooling platform 1. The setting of the second slope 102 can prevent the liquid molten salt from flowing out of the end of the cooling platform 1, while the smooth transition can ensure that the scraper 8 can smoothly push the broken molten salt into the recycling bin 4.

[0046] In addition, since there may be a certain drop between the top of the recycling bin 4 and the cooling platform 1, in order to collect the broken molten salt particles as completely as possible, a powder flow pipe can be set at the end of the cooling platform 1 to guide the molten salt particles into the recycling bin 4.

[0047] In summary, to address the shortcomings of existing molten salt recovery schemes, this embodiment uses the discharge pipe 3 to pour liquid molten salt onto the cooling platform 1, thereby quickly forming a large-area uniform solid molten salt layer. The moving frame 5 drives the crushing roller 7 to efficiently crush the solid molten salt. At the same time, the scraper 8 at the bottom of the moving frame 5 can push the crushed molten salt to the recovery bin 4 for collection as the moving frame 5 moves.

[0048] This embodiment has a simple structure and reduced cost. By integrating the crushing and scraping functions into a single mobile unit, the crushing and recycling of molten salt after condensation are carried out simultaneously, which significantly simplifies the equipment structure and reduces manufacturing and maintenance costs.

[0049] Furthermore, it boasts a high degree of automation, achieving fully automated continuous operation from molten salt spreading, cooling, crushing to collection, resulting in a short material handling path and high production efficiency. Compared to traditional molten salt cooling and recovery schemes, this invention can shorten the processing time per cycle, enabling short-intermittent continuous recovery of liquid molten salt and significantly improving molten salt recovery efficiency.

[0050] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
