The main components of molten salt include halides of alkali metals and alkaline earth metals, nitrates, sulfates, etc. Molten salt is a liquid ionic compound at high temperatures, with high heat capacity, good thermal conductivity and stability. In the process of molten salt heat exchange, ultra-high temperature molten salt needs to be introduced into the heat exchange device for heat exchange.

[0003] For example, the patent with announcement number CN210425559U (a molten salt energy storage heat exchange device) includes a heat exchange mechanism and a feeding pipe. A feeding mechanism is provided below the heat exchange mechanism, and a material exchange mechanism is provided below the heat exchange mechanism.

The No. 1 motor is installed on one side of the discharge pipe, and a sealing cover is provided on the other side of the discharge pipe.

[0004] While the existing technology facilitates the addition and replacement of molten salt, the heater used for heat preservation is located in the middle of the interior. Consequently, during the molten salt heat exchange process, the heat of the molten salt on the outside will dissipate outward through the shell of the box, resulting in a large waste of heat and poor energy efficiency. Therefore, there is an urgent need in the market to develop an ultra-high temperature molten salt heat exchange energy-saving device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-high temperature molten salt heat exchange energy-saving device to solve the problem mentioned in the background art that the heat of the molten salt on the outside during the molten salt heat exchange process will be dissipated outward through the shell of the box, resulting in a large amount of heat waste and poor energy efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultra-high temperature molten salt heat exchange energy-saving device, comprising a device housing, an internal material chamber, and an external heat exchange chamber. A temperature-conducting cylinder is fixedly installed between the material chamber and the heat exchange chamber. The temperature-conducting cylinder is made of die-cast aluminum alloy, and a heat exchange tube is spirally wound around the outside of the temperature-conducting cylinder. One end of the heat exchange tube extends to the upper side of one side of the device housing and is fixedly installed with a water inlet pipe, while the other end of the heat exchange tube extends to the lower side of the other side of the device housing and is fixedly installed with a water outlet pipe.

[0007] Preferably, a spiral groove is provided on the outer surface of the temperature conducting cylinder, and the heat exchange tube is embedded in the spiral groove of the temperature conducting cylinder, and a heat insulation layer is provided on the outer side of the inner part of the device box.

[0008] Preferably, a central shaft is rotatably mounted inside the material chamber of the device housing, and a stirring blade is fixedly mounted on the outside of the central shaft.

[0012] Preferably, a second valve is fixedly installed on one side of the device housing, and the second valve is connected to the output chamber. An output pipe is fixedly installed on one side of the second valve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention effectively solves the problem of energy waste caused by heat dissipation through the shell of the molten salt heat exchanger by setting a heat exchange chamber and a temperature-conducting cylinder made of die-cast aluminum alloy inside the device housing and using a spirally wound heat exchange tube design. Furthermore, by utilizing the excellent thermal conductivity of the temperature-conducting cylinder, the heat dissipated by the molten salt is efficiently transferred to the circulating water inside the heat exchange tube, realizing the full utilization and recovery of heat. This not only reduces heat loss but also significantly improves heat exchange efficiency and overall energy-saving performance, thus effectively overcoming the defects of large heat waste and poor energy efficiency in traditional molten salt heat exchange systems.

[0015] This invention, through the design of spiral grooves, ensures close contact between the heat exchange tube and the heat-conducting cylinder, maximizing the heat exchange area and thereby improving the heat transfer efficiency from molten salt to the water inside the heat exchange tube, further reducing heat loss. The insulation layer effectively blocks heat exchange between the external air and the internal high-temperature molten salt, reducing unnecessary heat loss, improving the overall energy efficiency ratio of the device, and enhancing energy-saving effects.

[0016] This invention, through the setting of a central shaft and stirring blades, drives the central shaft to rotate the stirring blades, which can agitate the molten salt in the material chamber, ensure a more uniform temperature distribution of the molten salt in the material chamber, avoid local overheating or cooling, and reduce the risk of molten salt crystallizing due to temperature differences.

[0022] 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.

[0023] Please see Figure 1-4 An embodiment of this utility model provides an ultra-high temperature molten salt heat exchange energy-saving device, including a device housing 1. The device housing 1 has a material cavity inside, and a heat exchange cavity 101 is arranged inside the device housing 1 along the outer side of the material cavity. A temperature conducting cylinder 14 is fixedly installed inside the device housing 1 between the material cavity and the heat exchange cavity 101. The temperature conducting cylinder 14 is made of die-cast aluminum alloy. A heat exchange tube 12 is spirally wound on the outer side of the temperature conducting cylinder 14. One end of the heat exchange tube 12 extends to the upper side of one side of the device housing 1 and is fixedly installed with a water inlet pipe 11. The other side of the heat exchange tube 12 extends to the lower side of the other side of the device housing 1 and is fixedly installed with a water outlet pipe 13.

[0024] In use, ultra-high temperature molten salt is fed into the material chamber of the device housing 1. The heat of the molten salt dissipates outward. By spirally setting the heat exchange tube 12 outside the material chamber of the device housing 1, the heat dissipated by the molten salt can be directly used for heat exchange, reducing heat loss and increasing energy efficiency. Furthermore, by setting the temperature-conducting cylinder 14 made of die-cast aluminum alloy, the temperature transfer capability can be improved, the heat exchange efficiency can be increased, heat loss can be reduced, and energy efficiency can be further improved.

[0025] Furthermore, a spiral groove is provided on the outer surface of the temperature conducting cylinder 14, and the heat exchange tube 12 is embedded in the spiral groove of the temperature conducting cylinder 14. A heat insulation layer 15 is provided on the outer side of the inner side of the device housing 1. The heat insulation layer 15 is made of glass fiber heat insulation material.

[0026] The spiral groove design ensures close contact between the heat exchange tube 12 and the heat conduction cylinder 14, maximizing the heat exchange area and thus improving the heat transfer efficiency from molten salt to water, further reducing heat loss. The insulation layer 15 effectively blocks the heat exchange between the external air and the internal high-temperature molten salt, reducing unnecessary heat loss, improving the energy efficiency ratio of the entire device, and enhancing energy saving effect.

[0027] Furthermore, a central shaft 6 is rotatably installed inside the material chamber of the device housing 1, and a stirring blade 7 is fixedly installed on the outside of the central shaft 6. A drive motor for the central shaft 6 is installed above the device housing 1.

[0028] The device housing 1 has a design that rotatably mounts a central shaft 6 and a stirring blade 7 inside the material chamber. By driving the central shaft 6 to rotate the stirring blade 7, it can ensure that the temperature distribution of the molten salt in the material chamber is more uniform, avoid local overheating or cooling, and reduce the risk of molten salt crystallizing due to temperature differences.

[0029] Furthermore, a transmission plate 8 is fixedly installed on one side of the stirring blade 7, a strip plate 9 is fixedly installed on one side of the transmission plate 8, and a scraper 10 is fixedly installed on one side of the strip plate 9. Through the rotation of the stirring blade 7 and the transmission of the transmission plate 8, the strip plate 9 can drive the scraper 10 to scrape the inner wall of the temperature conducting cylinder 14 to prevent molten salt from crystallizing and adhering on the inner wall of the temperature conducting cylinder 14.

[0030] The design of the stirring blade 7 driving the scraper 10 to scrape the inner wall of the temperature conducting cylinder 14 through the transmission plate 8 and the strip plate 9 can clean the inner wall of the temperature conducting cylinder 14 and prevent molten salt from crystallizing and accumulating here. This not only maintains the heat exchange efficiency but also extends the service life of the equipment.

[0031] Furthermore, a valve 3 is fixedly installed on the top of the device housing 1. The valve 3 is connected to the material chamber. A feed pipe 2 is fixedly installed above the valve 3. The feed pipe 2 is connected to an ultra-high temperature molten salt supply device.

[0032] The arrangement of valve 3 and feed pipe 2 provides a convenient way to add molten salt, improving production efficiency and operational flexibility.

[0033] Furthermore, an output cavity 102 is provided at the bottom inside the device housing 1, and the output cavity 102 is connected to the material cavity. An output shaft 16 is rotatably installed inside the output cavity 102 of the device housing 1. A drive motor for the output shaft 16 is provided inside the device housing 1. A spiral blade 17 is fixedly installed on the outside of the output shaft 16.

[0034] The device housing 1 is designed with an output chamber 102 and a spiral blade 17 at the bottom. The rotation of the spiral blade 17 driven by the output shaft 16 can effectively push the molten salt out of the output chamber 102, so as to achieve continuous and uniform molten salt discharge.

[0035] Furthermore, a valve 4 is fixedly installed on one side of the device housing 1, and the valve 4 is connected to the output chamber 102. An output pipe 5 is fixedly installed on one side of the valve 4.

[0036] The opening and closing of valve 4 can flexibly adjust the discharge of molten salt according to production needs, while the output pipe 5 provides a direct channel for molten salt output, enhancing operability and flexibility.

[0037] Working principle: During use, ultra-high temperature molten salt is received into the material chamber through the feed pipe 2. The molten salt releases heat in the material chamber, and this heat is efficiently transferred through the temperature-conducting cylinder 14 made of die-cast aluminum alloy to the heat exchange tube 12 tightly embedded in its spiral groove. The water in the heat exchange tube 12 absorbs the heat and flows out, realizing the effective utilization of heat and improving energy efficiency. At the same time, it drives the central shaft 6 and the stirring blade 7 to rotate, ensuring uniform temperature distribution of molten salt and reducing the risk of crystallization. The design of the transmission plate 8, the strip plate 9 and the scraper 10 cleans the inner wall of the temperature-conducting cylinder 14 to prevent molten salt from adhering. In addition, the glass fiber insulation layer 15 on the outside of the device effectively blocks heat loss and improves energy efficiency. When the molten salt is discharged, the spiral blade 17 is driven to rotate by the output shaft 16, which continuously and evenly pushes the molten salt from the output chamber 102 to the output pipe 5.

[0038] 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.
