Description
Technical Field
[0001] This utility model relates to the field of energy storage technology, specifically a heating device for high-temperature molten salt energy storage. Background Technology
[0002] With the increasing demand for clean energy, renewable energy sources such as solar and wind power have been widely used. However, these renewable energy sources are intermittent and unstable. For example, solar energy cannot generate electricity at night or on cloudy or rainy days, and the power output of wind power is greatly affected by wind speed. This leads to an imbalance between energy supply and demand, requiring effective energy storage technologies to solve this problem. High-temperature molten salt energy storage, as an efficient energy storage method, can convert excess electrical or thermal energy into the thermal energy of molten salt for storage and release it when needed, thus ensuring a stable energy supply.
[0003] However, existing high-temperature molten salt energy storage heating devices usually require heating the outside of the salt storage tank during use. Most of these devices can only heat the outer wall of one type of salt storage tank. If it is necessary to uniformly heat the outer wall of other types of salt storage tanks, it is necessary to replace them with other types of heating devices. Replacing the heating devices will reduce the working speed and increase the production cost.
[0004] Therefore, a high-temperature molten salt energy storage heating device is proposed to solve the problems mentioned above. Utility Model Content

This solves the problem that most heating devices can only heat the outer wall of one type of salt storage tank. If it is necessary to uniformly heat the outer wall of other types of salt storage tanks, it is necessary to replace the heating device with another type. Replacing the heating device will reduce the working speed and increase the production cost.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example:
[0025] Please see Figure 1 - Figure 4 A heating device for high-temperature molten salt energy storage in this embodiment includes a rectangular base plate 1, a placement rack 2 fixedly connected to the top of the rectangular base plate 1, a salt storage tank 3 fixedly connected to the top of the placement rack 2, a feed inlet 4 connected to the top of the salt storage tank 3, and a movable frame 5 above the rectangular base plate 1.
[0026] The rectangular base plate 1 is equipped with a heating mechanism via a movable frame 5. The heating mechanism includes at least two movable plates 8, at least two heat-conducting plates 9, several heating rods 11, at least two sleeves 12, at least two threaded rods 13, and at least two rotating rings 14.
[0027] A threaded rod 15 is rotatably connected to the top of the rectangular base plate 1, and a transmission assembly is provided on the rectangular base plate 1 through the threaded rod 15;
[0028] When heating the salt storage tank 3, first turn the threaded rod 13. Under the action of the heating mechanism, the two moving plates 8 will drive the two heat-conducting plates 9 to contact the salt storage tank 3, and pour the molten salt into the salt storage tank 3 from the feed port 4. Start the heating rod 11 to heat the outer wall of the salt storage tank 3 through the heat conduction performance of the arc groove 10. Start the motor 16 and move the moving frame 5 through the transmission component to heat the outer wall of the salt storage tank 3 more evenly.
[0029] At this time, the outer wall of the salt storage tank 3 is heated evenly, and it can heat salt storage tanks 3 of different sizes, models and heights evenly, avoiding the problem that the heating device model needs to be changed when changing the model of the salt storage tank 3, thus improving the working speed and reducing the production cost.
[0030] Slide grooves 6 are provided on the inner walls of opposite sides of the movable frame 5, and sliders 7 are slidably connected to the inner walls of the slide grooves 6. The two movable plates 8 are symmetrically distributed.
[0031] The two sliders 7 are fixedly connected to the opposite sides of the moving plate 8 on the side that are close to each other. The two heat-conducting plates 9 are symmetrically distributed. The heat-conducting plates 9 are fixedly connected to one side of the moving plate 8 from the side. An arc groove 10 is provided on the top of the heat-conducting plate 9.
[0032] Several heating rods 11 are evenly distributed in the arc-shaped groove 10, and two sleeves 12 are symmetrically distributed. One end of the sleeve 12 is fixedly connected to the other side of the moving plate 8.
[0033] Two threaded rods 13 are symmetrically distributed. The threaded rods 13 penetrate the movable frame 5 from the side and are threadedly connected to the movable frame 5. One end of the threaded rods 13 that penetrates the movable frame 5 extends into the sleeve 12. A rotating ring 14 is slidably connected to the inner wall of the sleeve 12. The inner wall of the rotating ring 14 is fixedly connected to the outer wall of the threaded rods 13.
[0034] When heating different models of salt storage tanks 3, the threaded rod 13 is turned. Since the threaded rod 13 is threadedly connected to the moving frame 5, after turning the threaded rod 13, the threaded rod 13 will move on the moving frame 5. Since the threaded rod 13 is fixedly connected to the rotating ring 14, and the rotating ring 14 is rotatably connected to the sleeve 12, under the limiting effect of the slide groove 6 on the slider 7, the moving plate 8 will not rotate due to the rotation of the threaded rod 13. The moving plate 8 will drive the slider 7 to move in the slide groove 6 due to the movement of the threaded rod 13, so that the two heat-conducting plates 9 approach each other until they contact the outer wall of the salt storage tank 3. The heating rod 11 is then activated. The heating rod 11 will heat the outer wall of the salt storage tank 3 through the heat conduction performance of the heat-conducting plate 9.
[0035] At this time, the salt storage tanks 3 of different models were heated, making the device more flexible, reducing the time for changing heating devices, and improving work efficiency.
[0036] The transmission assembly includes a fixed plate 101 disposed above a rectangular base plate 1, the top of a threaded rod 15 passing through the fixed plate 101 and rotatably connected to the fixed plate 101, and the threaded rod 15 passing through a movable frame 5 and threadedly connected to the movable frame 5.
[0037] A motor 16 is installed above the fixed plate 101. The top of the threaded rod 15 is fixedly connected to the output end of the motor 16. A slide rod 17 is fixedly connected to the top of the rectangular base plate 1. The top of the slide rod 17 is fixedly connected to the bottom of the fixed plate 101. The slide rod 17 passes through the movable frame 5 and is slidably connected to the movable frame 5.
[0038] When the outer wall of the salt storage tank 3 is heated evenly, the motor 16 is started. The motor 16 will drive the threaded rod 15 to rotate. Since the moving frame 5 and the threaded rod 15 are threadedly connected, under the limiting action of the slide rod 17, the moving frame 5 will move up and down due to the rotation of the threaded rod 15, which will drive the two heat-conducting plates 9 to move, so as to facilitate the even heating of the outer wall of the salt storage tank 3.
[0039] At this time, the outer wall of the salt storage tank 3 is heated evenly, and salt storage tanks 3 of different heights can be heated evenly, which further improves the flexibility of the device and improves the efficiency of work.
