The following technical solutions are provided, and will be combined with Figures 1 - 4 be described in detail:

[0028] A material cooling device for inorganic salt production, comprising:

[0029] A cooling bin 1, one side of the top of the cooling bin 1 is communicated with a feed pipe 2, a throttle valve is installed on the pipe body of the feed pipe 2, one end of the cooling bin 1 far from the feed pipe 2 is arc-shaped, one side bottom of the cooling bin 1 close to the feed pipe 2 is communicated with a cold medium inlet pipe 3, and the other side bottom is communicated with a cold medium outlet pipe 4, and the middle part of the arc-shaped side of the cooling bin 1 is communicated with an overflow pipe 5.

[0030] A cooling plate 6 and an aggregate hopper 7, the cooling plate 6 is fixedly arranged above one side inside the cold zone bin, the aggregate hopper 7 is fixedly arranged on the other side inside the cooling bin 1, the cooling plate 6 is arranged obliquely downward, and its bottom end is connected to the upper edge of the aggregate hopper 7, and an overflow tank 601 is constructed at the upper end of the cooling plate 6;

[0031] The discharging mechanism 8 is arranged below the aggregate hopper 7. The discharging mechanism 8 is used to convey the cooled and precipitated inorganic salts outwards. The discharging mechanism 8 includes an injection barrel 801 connected to the lower end of the aggregate hopper 7. The injection barrel 801 obliquely penetrates upwards through the side wall of the cooling bin 1. A driving motor 802 is installed at the upper end of the injection barrel 801. The output shaft of the driving motor 802 is connected to a mounting rod 803. A screw blade 804 is arranged on the surface of the mounting rod 803. A discharge pipe 805 is connected to the bottom of the injection barrel 801 near the driving motor 802.

[0032] Workflow description:

[0033] Feeding stage: The inorganic salt solution to be cooled is fed into the cooling bin 1 through the feed pipe 2. The throttle valve is used to control the flow rate of the solution. The water solution first falls into the overflow tank 601. When the overflow tank 601 is filled with the water solution, the inorganic salt water solution will overflow outwards to the cooling plate 6 and flow down along the cooling plate 6.

[0034] Cooling stage: The cold medium flows into the cooling bin 1 from the cold medium inlet pipe 3 and flows out from the cold medium outlet pipe 4. It should be noted that in this technical solution, during the implementation process, a cooling system is also required. The cooling system consists of a refrigeration unit, a pump, and pipelines. The cooling medium generated by the refrigeration unit is sent into the cooling plate 6 bin through the pump by the cold medium inlet pipe 3. The heated cooling medium returns to the refrigeration unit through the pipeline for re-cooling, forming a closed cooling cycle. The solution is cooled when flowing on the cooling plate 6. The inorganic salts precipitate to form crystals due to the temperature drop and slide into the aggregate hopper 7 together with the water along the inclined cooling plate 6. Due to the action of gravity, the inorganic salt body sinks to the bottom of the aggregate hopper 7. When the water level in the aggregate hopper 7 reaches a certain height, it will overflow outwards from the overflow pipe 5.

[0035] Collection stage: The driving motor 802 in the discharging mechanism 8 works, and the screw blade 804 rotates to push the inorganic salts towards the discharge pipe 805, completing the collection of the inorganic salts.

[0036] Through the combined design of the cooling bin 1, the cooling plate 6, the aggregate hopper 7, and the discharging mechanism 8 of this inorganic salt production material cooling equipment, the continuous cooling of the inorganic salt solution can be realized, the production efficiency can be improved, the overall structure design is reasonable, and it is convenient for large-scale production.

[0037] As Figure 4 shown, in some embodiments, a return pipe 806 is connected between the upper side of the injection barrel 801 near the driving motor 802 and the cooling bin 1. More specifically, when the inorganic salt crystals and water enter the injection barrel 801 together, due to the differences in density and particle size, the heavier inorganic salt crystals will move along the injection barrel 801 towards the bottom, while the water is lighter and is more likely to stay in the upper layer. At this time, the return pipe 806 serves as a channel to guide the upper layer solution containing more water back into the cooling bin 1.

[0038] As Figure 4 shown, in some embodiments, the top of the cooling plate 6 is equally spaced with protrusions 602. The protrusions 602 are arc-shaped. More specifically, the structure of the protrusions 602 can effectively delay the flowing speed of the aqueous solution on the cooling plate 6. This delaying effect increases the contact time between the solution and the cooling plate 6, making the heat exchange more sufficient, thereby promoting the more efficient precipitation of inorganic salts from the solution. The arc design conforms to the natural stacking form of inorganic salt crystals. Utilizing the action of gravity, it promotes the natural sliding of the crystals along the cooling plate 6, reducing the accumulation and bridging of crystals on the cooling plate 6.

[0039] As Figure 3 shown, in some embodiments, the number of the overflow pipes 5 is two, and they are located on both sides of the cooling bin 1. Valves are installed on the pipe bodies of the overflow pipes 5. More specifically, two overflow pipes 5 are provided. One of the overflow pipes 5 is mainly used to guide the water after the precipitation of inorganic salts to the waste water tank. When the cooling process is completed, most of the inorganic salts in the solution have been precipitated by cooling and collected through the aggregate hopper 7. At this time, the remaining water and other dissolved solids need to be separated and treated. Through this overflow pipe 5, the waste liquid can be effectively discharged from the cooling bin 1 for further treatment or disposal. The function of the other overflow pipe 5 is to introduce the water into the reserve tank body. These waters may still contain a small concentration of inorganic salts. Therefore, through the action of the water pump, it can be introduced into the cooling bin 1 again for reuse and cooling. This process not only reduces the consumption of water but also increases the recovery opportunity of the residual inorganic salts in the water until most of the inorganic salts are precipitated by cooling.

[0040] As Figure 4 shown, in some embodiments, the side wall of the cooling bin 1 is a hollow structure, and its interior is filled with heat-insulating cotton 101. More specifically, the hollow structure forms a heat-insulating layer. Since air is a poor conductor, the air layer in the hollow part serves as an additional heat-insulating barrier, enhancing the overall heat-insulating effect of the cooling bin 1. The heat-insulating cotton 101 filled in the side wall of the cooling bin 1 is a highly efficient heat-insulating material, which can significantly reduce the heat exchange speed between hot and cold energies. During the cooling process, the heat-insulating cotton 101 effectively prevents the heat transfer between the low temperature inside the bin and the external environmental temperature, thereby reducing the loss of cold energy.

[0041] As Figure 2 shown, in some embodiments, a temperature sensor 9 is installed at the bottom side of the front of the cooling bin 1, and the detection end of the temperature sensor 9 extends into the interior of the cooling bin 1. More specifically, the temperature sensor 9 can monitor the temperature inside the cooling bin 1 in real time to ensure that the temperature is controlled within the optimal range suitable for the precipitation of inorganic salts during the production process.

[0042] As Figure 2As shown, in some embodiments, an operation opening 102 is formed in the middle of the top of the cooling bin 1, and a transparent baffle 10 is movably arranged at the operation opening 102. More specifically, although the continuously flowing aqueous solution can cause the precipitated inorganic salt crystals to enter the aggregate hopper 7 along the cooling plate 6, there is still a small amount of inorganic salt adhering to the cooling plate 6. Through the operation opening 102, these attachments can be easily removed to maintain the efficiency and cleanliness of the cooling plate 6. The transparent baffle 10 enables the operator to directly observe the situation inside the cooling bin 1, including the flow state of the solution, the precipitation of inorganic salt crystals, and the working condition of the cooling plate 6.

[0043] As Figure 2 shown, in some embodiments, guide strips 11 are fixedly arranged at the edge of the operation opening 102, and a U-shaped slider 12 is fixedly arranged at the end of the transparent baffle 10. The U-shaped slider 12 is slidably connected to the guide strip 11. More specifically, the guide strip 11, as a track fixed at the edge of the operation opening 102, provides a stable sliding path for the U-shaped slider 12. This design ensures the smooth movement of the transparent baffle 10 during the opening and closing process.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
