Description

Technical Field

[0001] This utility model relates to the field of anhydrous sodium sulfate processing technology, specifically to an anhydrous sodium sulfate processing and purification device. Background Technology

[0002] Anhydrous sodium sulfate is an important chemical raw material with wide applications in glass manufacturing, detergent production, papermaking and other fields.

[0003] Traditional anhydrous sodium sulfate production processes often suffer from high energy consumption, severe environmental pollution, and unstable product quality. Especially during purification, effectively removing impurities while maintaining high production efficiency and product quality is one of the main challenges facing the industry. Existing purification methods mostly rely on simple precipitation or recrystallization methods. While these methods can remove impurities to some extent, their effectiveness in removing trace impurities is limited, making it difficult to meet the high-end market's demand for high-quality anhydrous sodium sulfate. Therefore, a high-quality anhydrous sodium sulfate processing and purification device is needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a high-quality anhydrous sodium sulfate processing and purification device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an anhydrous sodium sulfate processing and purification device, including a support base, a dissolving tank, a filter and a processing box;

[0006] After the dissolving tank is fixed on the support base, the top is connected to the feed pipe and the solvent pipe. After the raw material enters the dissolving tank through the feed pipe, the chemical solvent enters the dissolving tank through the solvent pipe and is fully mixed with the help of the heating plate on the inner wall of the dissolving tank.

[0007] The mixed solution enters the filter on the support base through the feed pipe. After the filter removes impurities, the solution is introduced into the processing tank. The temperature control mechanism in the processing tank works to concentrate and crystallize the solution. A discharge valve is connected to one side of the processing tank, and a one-way exhaust valve is connected to the top of the other side.

[0008] As an improvement, it also includes ion exchange columns, which are set on a support base and are evenly arranged in multiples. The ion exchange columns are connected to each other. After the feed port of the end ion exchange column is connected to the discharge port of the filter, the discharge port of the other end ion exchange column is connected to the feed port of the treatment box. The heavy metal ions are removed from the water by the exchangeable ions on the ion exchange resin and the heavy metal ions in the solution.

[0009] As an improvement, the temperature control mechanism includes a heating element and a cooling plate;

[0010] The processing chamber is equipped with an inclined plate. After the solution falls onto the inclined plate, the heating plate located below the inclined plate works to concentrate the solution. After the solution becomes supersaturated, the cooling plate works to slowly cool and crystallize the solution. The heating tube and the cooling plate are evenly connected to an external temperature controller.

[0011] As an improvement, a vibration motor is also included, which is installed on the outer wall of the processing chamber.

[0012] As an improvement, a stirrer is installed inside the dissolving tank, and a rotating motor fixed to the bottom of the dissolving tank drives the stirrer to rotate.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. By adding chemical agents to the dissolving tank, heavy metals are precipitated as insoluble compounds. Combined with a filter, this can significantly reduce the impurity content in the product, especially difficult-to-treat heavy metal ions and other organic pollutants.

[0015] 2. Use a temperature control mechanism to perform efficient concentration and crystallization processes, thereby improving purification efficiency. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. Example 1

[0023] An anhydrous sodium sulfate processing and purification device, combined with an auxiliary Figure 1 and 3 As shown, it includes a support base 1 and a dissolving tank 2. After the dissolving tank 2 is fixed on the support base 1, a feed pipe 4 and a solvent pipe 5 are connected to the top. After the raw material enters the dissolving tank 2 through the feed pipe 4, the chemical solvent enters the dissolving tank 2 through the solvent pipe 5 and is fully mixed with the cooperation of the heating plate 6 on the inner wall of the dissolving tank 2. A stirrer 14 is rotatably installed inside the dissolving tank 2, and a rotating motor 15 fixed on the bottom surface of the dissolving tank 2 drives the stirrer 14 to rotate. Example 2

[0024] Based on Example 1, combined with Appendix Figure 2-4 As shown, the processing tank 16 and filter 3 are connected. The mixed solution enters the filter 3 on the support base 1 through the feed pipe. After the filter 3 removes impurities, the solution is introduced into the processing tank 16. The temperature control mechanism in the processing tank 16 works to concentrate and crystallize the solution. One side of the processing tank 16 is connected to the discharge valve 7, and the top of the other side is connected to the one-way exhaust valve 8. The temperature control mechanism includes a heating tube 10 and a cooling plate 11. An inclined plate 12 is provided in the processing tank 16. After the solution falls above the inclined plate 12, the heating tube 10 located below the inclined plate 12 works to concentrate the solution. After the solution is supersaturated, the cooling plate 11 works to slowly cool and crystallize the solution. The heating tube 10 and the cooling plate 11 are uniformly connected to external temperature controllers.

[0025] It also includes a vibration motor 13, which is installed on the outer wall of the processing box 16 to facilitate crystallization feeding. At the same time, the installation of the vibration motor 13 facilitates crystallization.

[0026] It also includes ion exchange columns 9, which are set on the support base 1 and are evenly arranged in multiples. Each ion exchange column 9 is connected to the other. After the feed port of the end ion exchange column 9 is connected to the discharge port of the filter 3, the discharge port of the other end ion exchange column 9 is connected to the feed port of the treatment box 16. The heavy metal ions are removed from the water by the exchangeable ions on the ion exchange resin and the heavy metal ions in the solution.

[0027] In practical implementation, the raw materials enter the dissolving tank 2 through the feed pipe 4, and the chemical solvent enters the dissolving tank 2 through the solvent pipe 5. The heating plate 6 on the inner wall of the dissolving tank 2 heats the mixture to ensure thorough mixing. The rotating motor 15 fixed to the bottom of the dissolving tank 2 drives the stirrer 14 to rotate, improving the mixing efficiency. After mixing, the heavy metals form insoluble compounds and precipitate. The solution then enters the filter 3, where the filter screen removes impurities and other precipitates. The pre-purified solution then enters multiple ion exchange columns 9 in sequence. The exchangeable ions on the ion exchange resins exchange with the heavy metal ions in the solution, thereby removing the heavy metal ions from the water. Finally, the purified solution enters the processing tank 16, where the heating tube 10 concentrates the solution. After the solution becomes supersaturated, the cooling plate 11 slowly cools and crystallizes the solution. The vibration motor 13 induces spontaneous crystal nucleation. The heating tube 10 and the cooling plate 11 achieve the concentration and crystallization process. The resulting anhydrous sodium sulfate is removed by opening the discharge valve 7, and the vibration motor 13 promotes the discharge.

In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
