[0002] Electrothermal molten salt energy storage heating is an advanced energy storage technology that uses molten salt as an energy storage medium, heats the molten salt with electrical energy and stores the thermal energy, and releases the thermal energy for heating when needed. The basic principle of electrothermal molten salt energy storage heating technology is that during periods of sufficient power supply and low electricity prices, electrical energy is used to heat the molten salt, converting electrical energy into thermal energy and storing it in the molten salt, and outputting it for heat exchange when in use.

[0003] For example, the patent with publication number CN209371376U (an electric heating molten salt heating device) includes a container and a cavity. The container is provided with a heat exchange tube inside. An electric heating element is inserted in the heat exchange tube. The cavity is located at the top of the container and communicates with the container. The cavity is provided with a flow distributor and communicates with the fluid inlet.

[0004] While the aforementioned existing technologies can save a significant amount of cost for the thick cable cores used in low-voltage, high-current applications, the heating structure is fixedly installed inside the container, making disassembly difficult during cleaning and maintenance. This reduces the efficiency of cleaning and maintenance, increases the difficulty of device maintenance, and extends downtime. Therefore, there is an urgent market need to develop an electrothermal molten salt energy storage and heating technology device to help people solve these existing problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 The present invention provides an embodiment of an electrothermal molten salt energy storage and heating technology device, comprising a device housing 1, a top cover 2 provided on the top of the device housing 1, an electric heating tube 7 installed below the top cover 2, an energy storage cavity 101 provided inside the device housing 1, and lifting cavities 102 symmetrically arranged on both sides of the energy storage cavity 101 inside the device housing 1, a lifting plate 8 provided inside the lifting cavity 102, the lifting plate 8 being fixedly connected to the top cover 2, a threaded cavity provided inside the lifting plate 8, and a threaded rod 9 threadedly installed inside the threaded cavity of the lifting plate 8, the lower end of the threaded rod 9 extending to the lower part of the lifting plate 8 and rotatably connected to the device housing 1.

[0023] The top cover 2 and the heating element 7 below it can be raised and lowered by rotating the threaded rod 9. This allows the heating element 7 to be lifted from inside the device housing 1 when cleaning and maintenance are required, avoiding the disassembly difficulties caused by traditional fixed installation methods, improving the cleaning and maintenance efficiency of the heating structure, and reducing the maintenance difficulty and downtime of the device.

[0024] Furthermore, a transmission cavity 103 is provided at the bottom inside the device housing 1. A transmission shaft 12 is provided inside the transmission cavity 103. Gears 15 are fixedly installed at both ends of the transmission shaft 12. Gears 14 are meshed on one side of each gear 15. A vertical shaft 13 is fixedly installed inside the gear 14. Both ends of the vertical shaft 13 pass through the gear 14 and are rotatably connected to the device housing 1. The vertical shaft 13 is fixedly connected to the threaded rod 9.

[0025] The linkage design of the transmission shaft 12, gear 2 15, gear 1 14 and vertical shaft 13 in the transmission cavity 103 provides a power transmission path for the rotation of the threaded rod 9. By driving the transmission shaft 12 to rotate, the gear 2 15 is driven to rotate, and the gear 1 14 is driven to rotate through meshing transmission. Then, the threaded rod 9 is driven to rotate through the vertical shaft 13. Thus, through the linkage of the transmission mechanism, the two threaded rods 9 can be rotated at the same time, which improves the lifting efficiency of the heating tube 7 and makes maintenance operations more convenient.

[0026] Furthermore, a gear 17 is fixedly installed on the outer side of the drive shaft 12, and a gear 16 is meshed on one side of the gear 17. A protective cover 10 is fixedly installed below the device housing 1. An electric motor 11 is installed inside the protective cover 10 and is fixedly connected to the device housing 1. The output end of the electric motor 11 is fixedly connected to the gear 16.

[0027] The installation of motor 11, gear 4 17 and gear 3 16 improves the automation level of the equipment. By starting motor 11, the heating element 7 can be automatically raised and lowered without manual intervention, which further improves maintenance efficiency and reduces labor intensity. At the same time, the design of protective cover 10 also protects motor 11 from damage by the external environment.

[0028] Furthermore, four heating elements 7 are provided, and the four heating elements 7 are respectively fixedly installed at the front end, rear end and both sides below the top cover 2.

[0029] The even distribution of the four heating elements 7 allows the molten salt to be heated more uniformly within the energy storage chamber 101, improving heating efficiency and shortening heating time. At the same time, the design of multiple heating elements 7 also increases the redundancy of the device. When one heating element fails, the other heating elements can continue to work, ensuring the stability and reliability of the equipment.

[0030] Furthermore, a feed pipe 3 is provided in the middle above the top cover 2, and a discharge pipe 4 is provided below the front end of the device box 1. Electric valves are provided at the connection between the feed pipe 3 and the top cover 2 and at the connection between the discharge pipe 4 and the device box 1.

[0031] The design of the feed pipe 3 and the discharge pipe 4 allows molten salt to be added into the energy storage chamber 101 through the feed pipe 3 and the heated molten salt to be discharged through the discharge pipe 4, thus increasing practicality.

[0032] Furthermore, an operation panel 5 is fixedly installed at the front end of the device housing 1, and base legs 6 are fixedly installed at the four corners below the device housing 1.

[0033] The base leg 6 allows the device to be placed stably on the ground, increasing its practicality.

[0034] Working principle: During use, molten salt is stored in the energy storage chamber 101 inside the device housing 1. The molten salt is heated by four distributed electric heating tubes 7 installed below the top cover 2. When the electric heating tubes 7 need to be cleaned and maintained, the motor 11 inside the protective cover 10 is started. Its output end is fixedly connected to gear three 16, which can drive gear four 17 and transmission shaft 12 to rotate. When the transmission shaft 12 is driven to rotate, it can drive gear two 15 to rotate, which in turn drives gear one 14 to rotate through meshing transmission. Then, the vertical shaft 13 drives the threaded rod 9 to rotate, realizing the simultaneous rotation of the two threaded rods 9. The lifting plate 8 in the lifting chamber 102 is fixedly connected to the top cover 2, realizing the lifting and lowering of the top cover 2 and the electric heating tubes 7 below it. This allows the electric heating tubes 7 to rise and be exposed from inside the device housing 1, improving maintenance efficiency, reducing labor intensity, and increasing practicality.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
