DETAILED DESCRIPTION

Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example 1

[0046] See also Figure 1 - Figure 6 , the present application provides a molten salt electrode boiler with energy storage function, comprising:

[0047] The boiler body 100 is provided with a distribution pipe 101 for conveying low-temperature molten salt inside the boiler body 100. Nozzles are provided on the side of the upper end of the distribution pipe 101. The number of nozzles can be set according to actual needs. The low-temperature molten salt is supplied to the distribution pipe 101 from the outside, and the low-temperature molten salt is sprayed from multiple nozzles;

[0048] The energy storage conversion structure 200 is installed on the outside of the nozzle and uses the kinetic potential energy of the low-temperature molten salt to convert the stored energy. The energy storage conversion structure 200 can use the low-temperature molten salt to act on the conversion component 202, and use the kinetic potential energy to drive the central axis 2025 to rotate and cut the magnetic flux lines to generate electrical energy, store the electrical energy, and use the stored electrical energy to function as the preheating component 300, so that the preheating component 300 preheats the bottom of the boiler furnace body 100, reduces the heat loss caused by the high-temperature molten salt falling on the bottom of the boiler furnace body 100, and maintains high temperature. The molten salt is used in a suitable temperature range. The energy storage conversion structure 200 includes a conversion component 202 sleeved on the nozzle, an energy storage box 201 installed on the outer surface of the boiler body 100 for energy storage, and a wiring tube 203 installed between the conversion component 202 and the energy storage box 201. The energy storage box 201 is provided with an energy storage battery. The wiring tube 203 is a high-temperature resistant ceramic fiber tube. The wiring tube 203 is provided with a cable connecting the winding 2023 and the energy storage box 201. The wiring tube 203 is used to protect and insulate the cable.

[0049] And a preheating component 300 installed at the lower end of the boiler furnace body 100 to preheat it.

[0050] In this embodiment, preferably, the conversion component 202 utilizing the low-temperature molten salt kinetic potential energy conversion includes:

[0051] A heat-resistant outer shell 2021 is fixedly mounted on the nozzle. Both the heat-resistant outer shell 2021 and the heat-resistant inner shell 2022 are made of high-temperature resistant zirconia shells, which provide high-temperature protection. A rotating blade group 2028 is provided inside the left end of the heat-resistant outer shell 2021 near the nozzle. The structure of the nozzle can be set according to actual production needs, and can be a high-pressure nozzle. The ejection force meets the potential energy required for the rotation of the rotating blade group 2028.

[0052] The heat-resistant inner shell 2022 is located inside the heat-resistant outer shell 2021, and multiple reinforcement brackets are set between the two, which do not affect the flow of low-temperature molten salt and can fix the heat-resistant inner shell 2022. A reinforcement seat 2029 is set between the two adjacent heat-resistant outer shells 2021 above and below, and a winding 2023 is set on the inner surface of the heat-resistant inner shell 2022;

[0053] The central shaft 2025 installed at the center of the heat-resistant inner shell 2022 can drive the central shaft 2025 to rotate as the rotating blade group 2028 rotates, thereby driving the permanent magnet 2024 to rotate. The central shaft 2025 is provided with a permanent magnet 2024 that cooperates with the winding 2023.

[0054] In this embodiment, preferably, a guide nozzle 20210 is connected to the left end of the heat-resistant inner shell 2022. The guide nozzle 20210 is conical, which is convenient for guiding the low-temperature molten salt passing through the rotating blade group 2028, so that the low-temperature molten salt continues to flow and act on the electrode plate 103. A sealing bearing 20212 is embedded between the guide nozzle 20210 and the center shaft 2025, so that the low-temperature molten salt will not enter the heat-resistant inner shell 2022. The specific sealing technology is an existing technology and will not be described in detail in this application. A stabilizing bearing 20211 is provided between the left end of the heat-resistant inner shell 2022 and the center shaft 2025, which supports and stabilizes the center shaft 2025 without affecting the rotation of the center shaft 2025.

[0055] In this embodiment, preferably, a bearing seat 2026 is provided at the right end of the heat-resistant inner shell 2022 for fixing the right end of the central axis 2025, which supports the right end of the central axis 2025. A material cavity 2027 is left between the heat-resistant inner shell 2022 and the heat-resistant outer shell 2021 for the low-temperature molten salt to pass through, and the annular material cavity 2027 has a distribution and diffusion effect on the low-temperature molten salt, which facilitates the diffusion of the columnar low-temperature molten salt and facilitates the diffused low-temperature molten salt to fully contact the surface of the electrode plate 103. The diffused low-temperature molten salt is thinner, and the thinner diffused low-temperature molten salt is heated to increase the sufficiency of the heating of the low-temperature molten salt.

[0056] In this embodiment, preferably, the preheating component 300 for preheating the bottom of the boiler furnace body 100 includes:

[0057] A protective shell 301 is fixedly mounted on the outer side of the lower end of the boiler furnace body 100. The protective shell 301 is a ceramic fiber shell with poor thermal conductivity. A preheating cavity is left between the inside of the protective shell 301 and the outer surface of the boiler furnace body 100 to facilitate the installation of the heating coil in the preheating cavity.

[0058] The side heating coil 302 is sleeved on the side of the lower end of the boiler furnace body 100, and the side heating coil 302 heats the side of the boiler furnace body 100;

[0059] And the bottom heating coil 303 installed at the bottom of the preheating chamber, the bottom heating coil 303 heats the bottom of the boiler furnace body 100, and a connecting wire pipe 304 is provided between the bottom heating coil 303 and the side heating coil 302 and the energy storage box 201 to facilitate the energy supply to the bottom heating coil 303 and the side heating coil 302.

[0060] In summary, when in use, the outside world supplies low-temperature molten salt to the distribution pipe 101, and the low-temperature molten salt is then sprayed out at high speed through the nozzle. The low-temperature molten salt sprayed out at high speed acts on the blades of the rotating blade group 2028. The blades are forced to rotate, driving the central shaft 2025 to rotate, and the central shaft 2025 drives the permanent magnet 2024 to rotate. The permanent magnet 2024 cuts the magnetic flux lines of the winding 2023 to generate electrical energy. The generated electrical energy is transmitted to the battery in the energy storage box 201 through the cable in the wiring tube 203 for storage. The stored electrical energy is discharged to power the bottom heating coil 303 and the side heating coil 302. The bottom heating coil 303 and the side heating coil 302 are heated and the heat is transferred to the bottom of the boiler furnace body 100 to preheat the bottom of the boiler furnace body 100. The whole process realizes the conversion of the potential energy of the low-temperature molten salt into mechanical energy and then into electrical energy. Finally, it is converted into thermal energy, which plays the role of energy storage and conversion, and preheats the bottom of the boiler furnace body 100, reducing the heat loss of the high-temperature molten salt falling on the bottom of the boiler furnace body 100, so that the high-temperature molten salt is maintained in a relatively suitable temperature range, and the low-temperature molten salt passing through the rotating blade group 2028 flows into the material cavity 2027 along the guide nozzle 20210 and continues to flow to the right. During the flow, it diffuses through the annular material cavity 2027. The diffused low-temperature molten salt is relatively thin and acts on the electrode plate 103, allowing the columnar low-temperature molten salt to diffuse into a thinner annular low-temperature molten salt, which is convenient for fully heating the low-temperature molten salt, solves the problem that the middle of the columnar low-temperature molten salt cannot be fully heated, increases the sufficiency of the heating of the low-temperature molten salt, and solves the problem of heat loss when the heated high-temperature molten salt falls on the bottom of the boiler furnace body 100.

[0061] Example 2

[0062] Reference Figure 7 and Figure 8 , which is the second embodiment of the present invention.

[0063] In this embodiment, preferably, by providing a mixing component 400, when the high-temperature molten salt falls on the bottom of the boiler furnace body 100, the potential energy of the fall can be used to drive the bottom blade 402 to rotate, thereby fully mixing the high-temperature molten salt at the bottom, so that the high-temperature molten salt can maintain a uniform temperature as a whole without temperature error, thereby solving the problem of uneven heating caused by uneven temperature of the discharged high-temperature molten salt. In addition, the materials of each component in the entire mixing component 400 meet the temperature requirements of the high-temperature molten salt, and the use will not be affected by the high temperature. The mixing component 400 installed inside the boiler furnace body 100 for mixing the high-temperature molten salt includes:

[0064] A bottom ring 401 is horizontally mounted inside the boiler body 100. An annular groove 403 is formed on the lower surface of the bottom ring 401. The cross-sectional shape of the annular groove 403 is not limited to the rectangular shape shown in this application, but may also be circular or wedge-shaped.

[0065] A plurality of bottom blades 402 are installed on the upper surface of the bottom ring 401 and are distributed obliquely along its circumference. The curvature and inclination of the bottom blades 402 are convenient for adapting to the falling high-temperature molten salt and facilitating force rotation.

[0066] The inner surface of the lower end of the boiler body 100 is provided with an arc-shaped support block 404 extending into the annular groove 403. The upper surface of the arc-shaped support block 404 is provided with balls to reduce the contact area with the annular groove 403 and facilitate the rotation of the bottom ring 401.

[0067] In summary, when in use, the low-temperature molten salt acts on the electrode plate 103 to heat it into high-temperature molten salt. The high-temperature molten salt is pressurized by the pressure component 500 and falls on the bottom blade 402. The bottom blade 402 is forced to drive the bottom ring 401 to rotate, and the annular groove 403 rotates along the arc-shaped support block 404, and the two will not be separated from each other. As the bottom blade 402 rotates, the arc-shaped and inclined bottom blade 402 stirs the high-temperature molten salt at the bottom of the boiler furnace body 100 as it rotates, and the rotation of the bottom ring 401 will not restrict each other with the distribution pipe 101 and the discharge pipe 102. The continuously falling high-temperature molten salt drives the bottom blade 402 to rotate, so that the high-temperature molten salt is fully mixed, so that the temperature of the high-temperature molten salt located in the boiler furnace body 100 is uniform and within the appropriate temperature range, and there will be no temperature error of the high-temperature molten salt in different parts, thereby increasing the convenience and stability of the use of the high-temperature molten salt.

[0068] Example 3

[0069] Reference Figure 9 , which is the third embodiment of the present invention.

[0070] In this embodiment, preferably, an electrode plate 103 is vertically provided inside the boiler furnace body 100 and is located on the right side of the nozzle. The electrode plate 103 heats the low-temperature molten salt falling on its surface and heats it into high-temperature molten salt. A pressure component 500 is provided at the lower end of the electrode plate 103 and is located above the right end of the bottom ring 401. All components of the pressure component 500 are high-temperature resistant components. The pressure component 500 can be used to collect the high-temperature molten salt, and the high-temperature molten salt can be pressurized and discharged onto the bottom blades 402. The high-temperature molten salt is tilted to act on the bottom blades 402 through the inclined pressure discharge pipe 503, so that the bottom blades 402 rotate to fully mix the high-temperature molten salt at the bottom of the boiler furnace body 100.

[0071] In this embodiment, preferably, the pressurizing member 500 for pressurizing the high-temperature molten salt flowing along the surface of the electrode plate 103 includes:

[0072] The collecting box 501 is fixedly mounted on the lower end of the electrode plate 103. The lower end of the electrode plate 103 is flush with the top of the collecting box 501. The upper surface of the collecting box 501 is provided with a slot for collecting the high-temperature molten salt, which is convenient for collecting the high-temperature molten salt.

[0073] The piston plate 502 is vertically installed inside the collection box 501. The piston plate 502 fits the inner wall of the collection box 501, which facilitates pushing the high-temperature molten salt to be discharged from the pressurized discharge pipe 503. A micro electric cylinder 505 is provided on the right side of the collection box 501 to drive the piston plate 502 to move.

[0074] In this embodiment, preferably, a plurality of pressurized discharge pipes 503 are provided on the lower surface of the collecting box 501 near the right side. The shape of the pressurized discharge pipes 503 can be set as needed, and the pressurized discharge pipes 503 are inclined, so that the discharged high-temperature molten salt acts on the bottom blade 402 obliquely, which facilitates the rotation of the bottom blade 402. The pressurized discharge pipes 503 are located on the left side of the piston plate 502, and an electric cylinder housing 504 is provided on the right side of the collecting box 501 to surround and protect the micro electric cylinder 505. The electric cylinder housing 504 is a high-temperature resistant housing. For details, please refer to the material of the heat-resistant housing 2021, which can protect the micro electric cylinder 505.

[0075] In this embodiment, preferably, a discharge pipe 102 is provided through the bottom of the boiler body 100 to facilitate the discharge of high-temperature molten salt, and switch valves are provided on the discharge pipe 102 and the distribution pipe 101.

[0076] In summary, when in use, the high-temperature molten salt flows downward along the electrode plate 103 and is collected by the collecting box 501. The micro-electric cylinder 505 is then used to drive the piston plate 502 to move to the left, pushing the high-temperature molten salt in the collecting box 501 to converge to the left. Part of it is discharged through the slot and falls on the bottom blade 402 through gravitational potential energy, driving the bottom blade 402 to rotate, while the other part is discharged through the pressurized discharge pipe 503. The pressurized high-temperature molten salt acts obliquely on the bottom blade 402, accelerating the rotation of the bottom blade 402, and driving the bottom ring 401 to rotate along the arc-shaped support block 404. The rotation of multiple bottom blades 402 allows the high-temperature molten salt gathered at the bottom of the boiler furnace body 100 to be fully mixed, so that the temperature of the high-temperature molten salt at the bottom is uniform, and there will be no temperature error, which increases the convenience and stability of the use of the high-temperature molten salt. When the low-temperature molten salt stops spraying, the bottom blade 402 stops rotating.

[0077] Example 4

[0078] This embodiment is obtained by combining the first embodiment, the second embodiment and the third embodiment.

[0079] During use, the potential energy of the low-temperature molten salt spray acts on the rotating blade group 2028, driving the central shaft 2025 to rotate, converting the potential energy into mechanical energy, and the central shaft 2025 drives the permanent magnet 2024 and the winding 2023 to rotate relative to each other, cutting the magnetic lines of force, converting the mechanical energy into electrical energy and storing it. The stored electrical energy is discharged to supply energy to the preheating component 300, converting the electrical energy into thermal energy, preheating the bottom of the boiler furnace body 100, so that when the high-temperature molten salt falls on the bottom of the boiler furnace body 100, the heat loss is reduced, and while the high-temperature molten salt falls, the pressure component 500 is used to heat and act on the mixing component 400, fully mixing the high-temperature molten salt, making the temperature of the high-temperature molten salt uniform and maintaining a suitable temperature range, increasing the convenience and stability of the use of the high-temperature molten salt.
