Description

Technical Field

[0001] This invention belongs to the field of sodium sulfate production technology, specifically relating to a sodium sulfate content detection device and its detection method. Background Technology

[0002] my country possesses abundant sodium sulfate resources, widely distributed in Sichuan, Yunnan, Hunan, Guangxi, and other regions. Sodium sulfate (Na₂SO₄·CaSO₄) is primarily used in the production of sodium sulfate (Na₂SO₄). Sodium sulfate, also known as anhydrous sodium sulfate, has a wide range of industrial applications. However, it readily absorbs moisture when exposed to air, forming sodium sulfate decahydrate. Sodium sulfate mainly contains water and impurities such as calcium and magnesium. The content of these impurities largely depends on the production process and is relatively fixed. Given its hygroscopic nature, it is necessary to determine the sodium sulfate content before the product leaves the factory to assess its quality. Existing methods for determining the sodium sulfate content in sodium sulfate are time-consuming and involve numerous steps, typically taking around 7 hours to analyze a single sample. This excessively long analysis time makes it very inconvenient for manufacturers to test the sodium sulfate content. Summary of the Invention

[0003] The purpose of this invention is to provide a sodium sulfate content detection device and method, which solves the problem of inconvenience caused by the cumbersome steps and long detection time of existing sodium sulfate content detection methods.

[0004] The technical solution adopted in this invention is as follows:

[0005] A sodium sulfate content detection device includes a mounting support frame. A pull-out filter plate is mounted on the lower part of the mounting support frame. A reaction assembly is mounted on the mounting support frame above the pull-out filter plate. The reaction assembly includes a connecting plate mounted on the mounting support frame. A guide hopper is connected to the lower surface of the connecting plate. The guide hopper is connected to a reaction cylinder. A reaction solution is placed inside the reaction cylinder. A pull-out baffle is provided at the bottom of the reaction cylinder. A receiving cup is provided below the pull-out filter plate. A dehydration assembly is mounted on the top of the mounting support frame. The dehydration assembly includes a dehydration chamber. A door is installed at the bottom of the dehydration chamber. A discharge chamber is provided below the door. A top cover is installed on the top of the dehydration chamber. A heater is provided inside the dehydration chamber. An exhaust pipe is connected to the dehydration chamber. A water absorption meter is installed inside the exhaust pipe.

[0006] Furthermore, the hatch electrical signal is connected to a trigger switch.

[0007] Furthermore, a handle is installed on the top cover.

[0008] Furthermore, the heater is an electric heater.

[0009] A detection method for sodium sulfate content detection device includes the following steps:

[0010] S1. According to the testing requirements, determine the content and volume of the reaction solution based on the weight of the sodium sulfate to be tested, and proceed to step S2.

[0011] S2, install the pull-out filter plate and reaction components on the mounting support frame in sequence, place the receiving cup under the pull-out filter plate for later use, and proceed to step S3;

[0012] S3. According to the detection requirements of step S1, weigh the corresponding weight of sodium sulfate to be tested and proceed to step S4.

[0013] S4, open the top cover of the dehydration component, place the sodium sulfate weighed in step S3 into the dehydration chamber, close the top cover, and proceed to step S5;

[0014] S5, start the heater to heat the sodium sulfate to be tested, so that the moisture in the sodium sulfate evaporates. The water vapor is discharged through the exhaust pipe and absorbed by the water absorption meter in the exhaust pipe, and then proceed to step S6.

[0015] S6, turn off the heater, read the data from the water absorption meter, obtain the mass of water in the sodium sulfate, and proceed to step S7;

[0016] S7, start the trigger switch to open the door, and the dehydrated sodium sulfate falls into the feed hopper through the feed chamber. It is then introduced into the reaction cylinder to react with the reaction solution. The reaction time is 30-40 minutes. Proceed to step S8.

[0017] S8. After the reaction is completed, precipitate is generated in the reaction chamber. At this time, pull out the pull-out baffle so that the clear liquid in the reaction chamber is filtered through the pull-out filter plate and enters the receiving cup for collection. After collection, replace and place another receiving cup for later use, and proceed to step S9.

[0018] S9, pull out the pull-out filter plate to let the precipitate in the reaction cylinder fall into the receiving cup, dry the precipitate in the receiving cup at a constant temperature, weigh the precipitate after drying, and proceed to step S10.

[0019] S10. Calculate the mass of sulfate ions in the precipitate based on its weight, and finally calculate the mass of anhydrous sodium sulfate. The ratio of the mass of anhydrous sodium sulfate to the mass of sodium sulfate weighed in step S3 is the content of sodium sulfate.

[0020] Furthermore, the reaction solution is a barium chloride solution, and the precipitate is barium sulfate.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. This invention includes a mounting support frame, with a pull-out filter plate clamped at the lower part of the mounting support frame. A reaction assembly is mounted on the mounting support frame above the pull-out filter plate. The reaction assembly includes a connecting plate mounted on the mounting support frame. A guide hopper is connected to the lower surface of the connecting plate. The guide hopper is connected to a reaction cylinder. A reaction solution is disposed inside the reaction cylinder. A pull-out baffle is disposed at the bottom of the reaction cylinder. A receiving cup is disposed below the pull-out filter plate. A dehydration assembly is mounted on the top of the mounting support frame. The dehydration assembly includes a dehydration chamber. A door is disposed at the bottom of the dehydration chamber. A discharge chamber is disposed below the door. A top cover is disposed on the top of the dehydration chamber. A heater is disposed inside the dehydration chamber. An exhaust pipe is connected to the dehydration chamber. A water absorption meter is installed inside the exhaust pipe.

[0023] This setup determines the content and volume of the reaction solution based on the weight of the sodium sulfate to be tested. The pull-out filter plate and reaction components are sequentially installed on the mounting support. The receiving cup is placed below the pull-out filter plate for later use. The corresponding weight of sodium sulfate to be tested is weighed. The top cover of the dehydration component is opened, and the weighed sodium sulfate is placed in the dehydration chamber. The top cover is closed, and the heater is started to heat the sodium sulfate to be tested, causing the water in the sodium sulfate to evaporate. The water vapor is discharged through the exhaust pipe and absorbed by the water absorption meter in the exhaust pipe. The heater is then turned off, and the data from the water absorption meter is read to obtain the mass of water in the sodium sulfate. The hatch is then opened, and the dehydrated sodium sulfate falls into the feed hopper through the feed chamber. It is then guided into the reaction chamber to react with the reaction solution for 30-40 minutes. After the reaction, precipitate forms in the reaction chamber. At this point, the pull-out baffle is pulled out, allowing the clarified liquid in the reaction chamber to be filtered through the pull-out filter plate and collected in the receiving cup. After collection, another receiving cup is placed for later use. The pull-out filter plate is then pulled out, allowing the precipitate in the reaction chamber to fall into the receiving cup. The precipitate in the receiving cup is then dried at a constant temperature. After drying, the precipitate is weighed, and the mass of sulfate ions in the precipitate is calculated based on the weight. Finally, the mass of anhydrous sodium sulfate is calculated. The ratio of the mass of anhydrous sodium sulfate to the mass of sodium sulfate weighed is the sodium sulfate content. This method quickly and efficiently detects the sodium sulfate content, effectively solving the problem of inconvenience caused by cumbersome procedures and long detection times in existing sodium sulfate content detection methods.
