Description

Technical Field

[0001] This utility model relates to the technical field of magnesium sulfate purification equipment, and in particular to a continuous extraction magnesium sulfate calcium removal device. Background Technology

[0002] Magnesium sulfate, also known as thiopicrosite or bitter salt, contains calcium, an impurity that is difficult to remove in general purification processes because it belongs to the same group as magnesium. Therefore, a device that can efficiently remove calcium impurities from magnesium sulfate is needed.

[0003] For example, in a class of prior art represented by the Chinese invention patent CN103058235B, which describes a method for removing calcium from magnesium sulfate and high-purity magnesium sulfate, the main steps include (1) adding water to a reaction vessel and adding magnesium sulfate under stirring conditions to form a magnesium sulfate solution; (2) adding hydrofluoric acid to the magnesium sulfate solution while stirring; (3) allowing it to stand, filtering, and removing calcium fluoride; and (4) cooling and crystallizing, drying the crystals, and obtaining high-purity magnesium sulfate.

[0004] However, the existing methods still have the following problems when used: the existing methods require the use of hydrofluoric acid for calcium removal, which places strict requirements on the reaction vessel, and the existing methods require mixing and heating magnesium sulfate solution and hydrofluoric acid for calcium removal, which is a high-risk process. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a continuous extraction magnesium sulfate calcium removal device that uses anhydrous alcohol for continuous extraction by setting up an extraction device and a water bath device to remove calcium from magnesium sulfate, thereby reducing the need for reaction vessels and the production hazards.

[0006] This utility model discloses a continuous extraction magnesium sulfate calcium removal device, comprising a machine body; it also includes an extraction device, a water bath device, a water replenishment device, an extraction device, and an outlet device. The extraction device, water bath device, water replenishment device, and extraction device are all mounted on the machine body, and the outlet device is mounted on the extraction device. The machine body provides support. The extraction device continuously extracts magnesium sulfate, the water bath device heats the extraction device, the water replenishment device replenishes water to the water bath device, the extraction device extracts magnesium sulfate from alcohol, and the outlet device facilitates the discharge of residual calcium impurities from the extraction device.

[0007] Preferably, the body includes a base plate, two supports (a first support, a second support, and a third support), with the first and third supports mounted on the top of the base plate, and the second support mounted on the first supports; providing support.

[0008] Preferably, the extraction device includes an extraction tank, a filter screen, a first tank cover, a condenser, a siphon tube, an alcohol tank, a second tank cover, an extraction tube, and a gas guide tube. The extraction tank is mounted on a second support. The top of the extraction tank has a feed inlet, the bottom of the filter screen has a discharge outlet, the bottom of the filter screen has a liquid outlet, and the top of the filter screen has a gas inlet. The filter screen is installed inside the extraction tank and has an opening at its bottom. The first tank cover is installed at the discharge outlet. The condenser is installed at the top of the feed inlet, with a coolant inlet and a coolant outlet on its side. The top of the condenser has a feed inlet.

The alcohol tank is installed at the bottom of the siphon tube, with a liquid outlet at its front end and an extraction outlet on its side. The top of the alcohol tank has an exhaust outlet. The second tank cover is installed at the feed outlet, the first extraction tube is installed at the extraction outlet, and the gas guide tube is installed at both the exhaust outlet and the gas inlet. The extraction tank is used for processing unpurified materials. Magnesium sulfate is stored in a precipitated form. A filter screen prevents calcium impurities from entering the alcohol tank with the alcohol during purification. A lid allows for easy removal of any remaining calcium impurities after purification. A condenser facilitates the addition of materials to the extraction tank. Anhydrous alcohol is placed in the alcohol tank. When the alcohol tank is heated, the alcohol inside evaporates. The alcohol vapor flows into the extraction tank and condenser through a gas guide pipe. Cooling liquid is introduced into the condenser, where the alcohol vapor condenses into liquid alcohol, which flows into the extraction tank. The alcohol then dissolves the magnesium sulfate. Calcium impurities, being insoluble in alcohol, remain inside the extraction tank. As the amount of alcohol in the extraction tank gradually increases, it enters the siphon section of the siphon tube. When the alcohol passes through the siphon section, the siphon effect causes the alcohol inside the extraction tank to be completely discharged back into the alcohol tank, achieving continuous extraction of magnesium sulfate. Excess magnesium sulfate precipitates to the bottom of the alcohol tank due to alcohol evaporation. A lid seals the alcohol tank, facilitating the addition of alcohol. An extraction tube allows for easy removal of magnesium sulfate from the alcohol tank.

[0009] Preferably, the water bath device includes a support four and multiple electric heaters. The support four is installed on the top of the base plate, and the alcohol tank is located inside the support four. The support four is provided with a water inlet and a water outlet on its side. The multiple electric heaters are installed on the inner side wall of the alcohol tank.

The motor provides power to drive the gear pumps to pump water from the water tank into the support and pump water from the support back into the water tank. This automatically replenishes water to the support and controls the water temperature inside the support, preventing the alcohol from overheating and improving production safety.

[0011] Preferably, the extraction device includes a second gear pump, a second reducer, a second motor, a mixing chamber, a second water tank, a pipeline filter membrane, an extraction tube, an extraction tube 3, a storage tank, and a third lid.

The third extraction tube is mounted on the bottom of the pipeline filter membrane. The storage tank is mounted on the bottom of the third extraction tube and is mounted on the top of the base plate. The third lid is mounted on the storage tank. At the top, motor two provides power, driving gear pump two to pump the magnesium sulfate mixed with alcohol inside the alcohol tank into the mixing chamber. Water tank two supplies water to the mixing chamber. The mixing chamber mixes water, alcohol and magnesium sulfate, dissolving solid magnesium sulfate and reducing the amount of magnesium sulfate dissolved in the alcohol.

The tank lid three seals the storage tank and facilitates the removal of alcohol from the storage tank for reuse, reducing production costs. When there is a large amount of magnesium sulfate dissolved in the water in water tank two, the water in water tank two can be removed and dried to obtain purified magnesium sulfate.

[0012] Preferably, the discharge device includes a bracket five and a bracket six. The bracket five is installed at the front end of the extraction tank, and the bracket six is ​​installed at the rear end of the bracket five.

[0030] First, open the lid 27 and add anhydrous alcohol to the alcohol tank 26. Then, add unpurified magnesium sulfate to the extraction tank 21 through the condenser 24. The extraction tank 21 stores the unpurified magnesium sulfate. Next, turn on the electric heater 32 to heat the water, thus heating the alcohol tank 26 in a water bath. When the alcohol tank 26 is heated, the alcohol inside evaporates. The alcohol vapor flows into the extraction tank 21 and the condenser 24 through the gas pipe 29. Coolant is introduced into the condenser 24, where the alcohol vapor condenses into alcohol. Liquid flows into extraction tank 21, where alcohol dissolves magnesium sulfate. Calcium impurities, being insoluble in alcohol, remain inside extraction tank 21. As the alcohol content in extraction tank 21 gradually increases, it enters the siphon section of siphon tube 25. When the alcohol passes through the siphon section, the siphon effect causes the alcohol in extraction tank 21 to be completely drained back into alcohol tank 26, achieving continuous extraction of magnesium sulfate. Filter screen 22 prevents calcium impurities from entering alcohol tank 26 with the alcohol during purification. Tank lid 23 facilitates the removal of any remaining calcium impurities after purification. Simultaneously, motor 44 is turned on. Motor 44 provides power to drive gear pump 42, which drains water from water tank 41 into support 31 and vice versa. It automatically replenishes water to support 31 and controls the water temperature inside to prevent overheating of the alcohol, thus improving production safety. When there is a high amount of magnesium sulfate in alcohol tank 26, motor 53 is activated, providing power to drive gear pump 51 to pump the magnesium sulfate-alcohol mixture from alcohol tank 26 into mixing chamber 54. Water tank 55 supplies water to mixing chamber 54. Water, alcohol, and magnesium sulfate are mixed to dissolve solid magnesium sulfate and reduce the amount of magnesium sulfate dissolved in the alcohol. The pipeline filter membrane 56 filters the mixed liquid discharged from the mixing chamber 54, allowing the alcohol to be discharged through the extraction tube 3 58 to the storage tank 59, while the water is discharged back to the water tank 2 55 through the extraction tube 2 57. The tank lid 3 60 seals the storage tank 59 and facilitates the removal of alcohol from the storage tank 59 for reuse, reducing production costs. When there is a large amount of magnesium sulfate dissolved in the water in the water tank 2 55, the water in the water tank 2 55 can be removed and dried to obtain purified magnesium sulfate. Example 2

[0031] like Figure 8 As shown, the embodiment also includes:

[0032] The export device 06 includes a fifth bracket 61 and a sixth bracket 62. The fifth bracket 61 is installed at the front end of the extraction tank 21, and the sixth bracket 62 is installed at the rear end of the fifth bracket 61.

[0033] First, open the lid 27 and add anhydrous alcohol to the alcohol tank 26. Then, add unpurified magnesium sulfate to the extraction tank 21 through the condenser 24. The extraction tank 21 stores the unpurified magnesium sulfate. Next, turn on the electric heater 32 to heat the water, thus heating the alcohol tank 26 in a water bath. When the alcohol tank 26 is heated, the alcohol inside evaporates. The alcohol vapor flows into the extraction tank 21 and the condenser 24 through the gas pipe 29. Coolant is introduced into the condenser 24, where the alcohol vapor condenses into liquid alcohol, which then flows into the extraction tank 21. Inside the extraction tank 21, the ethanol dissolves the magnesium sulfate. Calcium impurities, being insoluble in ethanol, remain inside. As the ethanol content in the extraction tank 21 increases, it enters the siphon section of the siphon tube 25. When the ethanol passes through the siphon section, the siphon effect causes the ethanol inside the extraction tank 21 to be completely discharged back into the ethanol tank 26, achieving continuous extraction of magnesium sulfate. The filter screen 22 prevents calcium impurities from entering the ethanol tank 26 during purification. The lid 23 facilitates the removal of any remaining calcium impurities after purification. The support 62 guides the calcium impurities discharged from the outlet of the extraction tank 21, facilitating the removal of impurities. Calcium impurities are removed, and simultaneously, motor 44 is turned on, providing power to drive gear pump 42 to drain water from water tank 41 into support 31 and vice versa. Water is automatically replenished to support 31, and the water temperature inside support 31 is controlled to prevent excessive heating of the alcohol and improve production safety. When there is a high amount of magnesium sulfate in alcohol tank 26, motor 53 is turned on, providing power to drive gear pump 51 to pump the magnesium sulfate mixed with alcohol from alcohol tank 26 into mixing chamber 54. Water tank 55 then pumps water into mixing chamber 54. Water supply and mixing chamber 54 mix water, alcohol and magnesium sulfate, dissolving solid magnesium sulfate and reducing the amount of magnesium sulfate dissolved in the alcohol. Pipeline filter membrane 56 filters the mixed liquid discharged from mixing chamber 54, allowing alcohol to be discharged through extraction pipe three 58 to storage tank 59, while water is discharged back to water tank two 55 through extraction pipe two 57. Tank lid three 60 seals storage tank 59 and facilitates the removal of alcohol from storage tank 59 for reuse, reducing production costs. When there is a large amount of magnesium sulfate dissolved in the water in water tank two 55, the water in water tank two 55 can be removed and dried to obtain purified magnesium sulfate.

[0034] like Figures 1 to 8As shown, this utility model discloses a continuous extraction-type magnesium sulfate calcium removal device. During operation, firstly, the tank cover 27 is opened, and anhydrous alcohol is added to the alcohol tank 26. Then, unpurified magnesium sulfate is added to the extraction tank 21 through the condenser 24. The extraction tank 21 stores the unpurified magnesium sulfate. Next, the electric heater 32 is turned on to heat water, thereby providing a water bath for heating the alcohol tank 26. When the alcohol tank 26 is heated, the alcohol inside evaporates. The alcohol vapor flows into the extraction tank 21 and the condenser 24 through the gas guide pipe 29. Cooling liquid is introduced into the condenser 24, and the alcohol vapor... Vapor condenses into liquid alcohol in condenser 24 and flows into extraction tank 21. The alcohol dissolves magnesium sulfate, while calcium impurities, being insoluble in alcohol, remain inside extraction tank 21. As the alcohol content in extraction tank 21 gradually increases, it enters the siphon section of siphon tube 25. When the alcohol passes through the siphon section, the siphon effect completely drains the alcohol from extraction tank 21 back into alcohol tank 26, achieving continuous extraction of magnesium sulfate. Filter 22 prevents calcium impurities from entering alcohol tank 26 with the alcohol during purification. Tank lid 23 facilitates the removal of any remaining calcium impurities after purification. Support 62 controls the discharge from extraction tank 21. The system guides the discharged calcium impurities for easy removal. Simultaneously, motor 44 is activated, providing power to drive gear pump 42, which drains water from water tank 41 into support 31 and vice versa. It automatically replenishes water to support 31 and controls the internal water temperature to prevent overheating of the alcohol, improving production safety. When there is a high amount of magnesium sulfate in alcohol tank 26, motor 53 is activated, providing power to drive gear pump 51, which pumps the magnesium sulfate-alcohol mixture from alcohol tank 26 into mixing chamber 54 and water tank 55. Water is supplied to mixing chamber 54, where water, alcohol, and magnesium sulfate are mixed to dissolve solid magnesium sulfate and reduce the amount of magnesium sulfate dissolved in the alcohol. Pipeline filter membrane 56 filters the mixed liquid discharged from mixing chamber 54, allowing alcohol to be discharged through extraction pipe three 58 to storage tank 59, while water is discharged back to water tank two 55 through extraction pipe two 57. Tank lid three 60 seals storage tank 59 and facilitates the removal of alcohol from storage tank 59 for reuse, reducing production costs. When a large amount of magnesium sulfate is dissolved in the water in water tank two 55, the water in water tank two 55 can be removed and dried to obtain purified magnesium sulfate.
