Description

Technical Field

[0001] This utility model relates to the field of fluid purification technology, and in particular to a brine purification device. Background Technology

[0002] Brine is a core raw material in the chlor-alkali industry and chemical synthesis. Natural or crude brine often contains impurities such as calcium and magnesium ions, sulfate ions, and silt, which can easily cause scaling in subsequent equipment, catalyst poisoning, and reduce product purity. Brine purification is a key process for removing these impurities, and it often relies on methods such as precipitation. However, this method suffers from problems such as incomplete impurity removal and low purification efficiency, making it difficult to meet the demands of modern industry for high-purity brine.

[0003] In industrial production, the core objective of brine purification is to control the content of impurities such as calcium and magnesium ions to meet the process requirements of ion-exchange membrane electrolysis and high-end chemical synthesis. Traditional brine purification equipment has two major problems: First, insufficient mixing. Unidirectional stirring easily creates eddy dead zones in the mixing drum, resulting in uneven mixing of brine and impurity removal agents in some areas. The agent concentration is too low in some areas, and calcium and magnesium ions cannot fully react to form precipitates, or the agent concentration is too high, resulting in waste. Ultimately, this leads to fluctuations in the purity of the purified brine and a high rate of non-compliance. Second, the filter components are difficult to maintain. Filter plates are prone to clogging due to long-term retention of impurities. In traditional equipment, replacing filter plates requires disassembling the housing and interrupting production, which seriously affects continuous production efficiency. Moreover, if clogged filter plates are not replaced in time, the filtration accuracy will decrease, and impurities will enter subsequent processes with the brine, causing scaling in the electrolytic cell, damage to the ion-exchange membrane, and other malfunctions, increasing equipment operation and maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a brine purification device, which aims to improve the problem that unidirectional stirring prevents brine from being fully mixed, resulting in uneven concentration and sediment accumulation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brine refining device, comprising a stirring drum, a fixed frame fixedly connected to the upper surface of the stirring drum, a motor fixedly connected to the outer wall of the fixed frame, a first bevel gear fixedly disposed at the output end of the motor, a second bevel gear meshing with the tooth end of the first bevel gear, a transmission rod fixedly connected to the inner wall of the second bevel gear, a transmission rod rotatably connected to the inner wall of the fixed frame, a receiving plate rotatably connected to the bottom end of the transmission rod, the upper surface of the receiving plate fixedly connected to the lower surface of the stirring drum, a first stirring blade fixedly connected to the outer wall of the transmission rod, a third bevel gear meshing with the tooth end of the first bevel gear, and a stirring assembly fixedly connected to the inner wall of the third bevel gear, the stirring assembly being used for reverse stirring.

[0006] The above technical solution involves starting the motor on the outer wall of the fixed frame to rotate the first bevel gear at the output end. When the first bevel gear rotates, it rotates the transmission rod through the meshing connection of the second bevel gear at the tooth end. This causes the transmission rod to rotate synchronously with the first stirring blade inside the device. When the hollow tube rotates, it drives the second stirring blade to stir in the opposite direction, achieving bidirectional stirring of the brine. This breaks the eddy dead zone that is easily formed by unidirectional stirring, making the brine more uniformly mixed and ensuring that the purity of the final purified brine meets the requirements for industrial use.

[0007] Preferably, the stirring assembly includes a hollow tube, the outer wall of which is fixedly connected to the inner wall of the third bevel gear, the inner wall of which is rotatably connected to the outer wall of the transmission rod, and a second stirring blade fixedly connected to the outer wall of the hollow tube. A funnel is fixedly connected to the lower surface of the receiving pan, and a baffle is slidably connected to the inside of the funnel. A housing is fixedly connected to the lower surface of the receiving pan, and a filter plate is slidably connected to the inner wall of the housing. A fixing block is fixedly connected to the outer wall of the housing, a rotating plate is rotatably connected to the inside of the fixing block, and a downward pressure shaft is fixedly connected to the outer wall of the rotating plate. The outer wall of the downward pressure shaft fits against the outer wall of the filter plate, a rotating shaft is rotatably connected to the inside of the fixing block, and a fixing plate is fixedly connected to the outer wall of the rotating shaft.

[0008] Preferably, the outer wall of the rotating shaft is slidably connected to the inner wall of the rotating plate, the outer wall of the fixed plate is rotatably connected to the outer wall of the rotating plate, a collection box is slidably connected to the inner wall of the housing, and a handle is fixedly connected to the outer wall of the collection box. Bolts are threaded into the interior of the housing, and the outer walls of the bolts are slidably connected to the interior of the filter plate.

[0009] This utility model has the following beneficial effects: 1. In this utility model, the interaction between the stirring drum, the fixed frame, the motor, the first bevel gear, the transmission rod, the first stirring blade, the third bevel gear, the hollow tube, and the second stirring blade achieves the effect of bidirectional stirring of brine. This helps to break the dead zone of eddy currents that are easily formed by unidirectional stirring, making the brine more uniformly mixed as a whole, avoiding the accumulation of impurities caused by uneven local concentration, and ensuring that the purity of the final purified brine meets the requirements for industrial use.

[0010] 2. In this utility model, through the mutual cooperation between the housing, filter plate, fixed block, rotating plate, lower pressure shaft, rotating shaft, and fixed plate, this structure achieves the effect of quickly replacing the filter plate through the linkage of the rotating plate and the lower pressure shaft. This facilitates the timely replacement of old plates that are blocked or whose pores are filled with impurities, restoring filtration accuracy, ensuring the impurity interception effect, and preventing unqualified brine from entering subsequent processes and affecting product purity. Compared with traditional devices, it shortens maintenance time and significantly improves continuous production efficiency. At the same time, the double fixing of the lower pressure shaft and the fixed plate ensures that the filter plate is not loose after installation, avoiding the increase of filtration gap due to vibration and reducing the impurity leakage rate.

[0013] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example 1: Reference Figures 1-3 This utility model provides an embodiment of a brine refining device, comprising a stirring cylinder 1, a fixed frame 2 fixedly connected to the upper surface of the stirring cylinder 1, a motor 3 fixedly connected to the outer wall of the fixed frame 2, a first bevel gear 4 fixedly mounted at the output end of the motor 3, a second bevel gear 5 meshing with the tooth end of the first bevel gear 4, a transmission rod 6 fixedly connected to the inner wall of the second bevel gear 5, the outer wall of the transmission rod 6 rotatably connected to the inside of the fixed frame 2, a receiving plate 8 rotatably connected to the bottom end of the transmission rod 6, the upper surface of the receiving plate 8 fixedly connected to the lower surface of the stirring cylinder 1, a first stirring blade 7 fixedly connected to the outer wall of the transmission rod 6, a third bevel gear 9 meshing with the tooth end of the first bevel gear 4, and a stirring assembly fixedly connected to the inner wall of the third bevel gear 9 for reverse stirring.

[0015] The stirring drum 1 supports and fixes the fixed frame 2, which in turn supports and fixes the motor 3, ensuring the stability of the motor 3 during operation. When the motor 3 starts, it drives the first bevel gear 4 at the output end to rotate, causing the second bevel gear 5, which is meshed with the first bevel gear 4, to rotate. The transmission rod 6 supports and fixes the second bevel gear 5, and the stirring drum 1 supports and fixes the receiving plate 8. Therefore, when the transmission rod 6 rotates, it rotates synchronously inside the fixed frame 2 and on the upper surface of the receiving plate 8. The fixed frame 2 and the receiving plate 8 support and fix the rotation of the transmission rod 6. The moving rod 6 supports and fixes the first stirring blade 7, causing the first stirring blade 7 to rotate synchronously inside the stirring cylinder 1 when the transmission rod 6 rotates. When the first bevel gear 4 rotates, it will simultaneously rotate the third bevel gear 9 connected to the tooth end. When the third bevel gear 9 rotates, it will drive the reverse stirring component to rotate synchronously. Thus, when the first stirring blade 7 rotates, it will cooperate with the reverse stirring component to perform bidirectional stirring of the brine, breaking the eddy dead zone that is easily formed by unidirectional stirring, making the brine more uniformly mixed, avoiding the accumulation of impurities caused by uneven local concentration, ensuring the stability of the purification process, and ensuring that the purity of the final purified brine meets the requirements for industrial use.

[0016] Reference Figures 1-3The stirring assembly includes a hollow tube 10. The outer wall of the hollow tube 10 is fixedly connected to the inner wall of the third bevel gear 9, and the inner wall of the hollow tube 10 is rotatably connected to the outer wall of the transmission rod 6. A second stirring blade 11 is fixedly connected to the outer wall of the hollow tube 10. The hollow tube 10 supports and fixes the third bevel gear 9. The hollow tube 10 is placed on the outer wall of the transmission rod 6 so that when the third bevel gear 9 rotates, it drives the hollow tube 10 to rotate synchronously on the outer wall of the transmission rod 6. The hollow tube 10 supports the rotation of the second stirring blade 11, and thus, when the hollow tube 10 rotates, it drives the second stirring blade 11 to stir in the opposite direction inside the device.

[0017] Reference Figures 4-6 A funnel 12 is fixedly connected to the lower surface of the receiving plate 8. A baffle 13 is slidably connected inside the funnel 12. A box 14 is fixedly connected to the lower surface of the receiving plate 8. A filter plate 15 is slidably connected to the inner wall of the box 14. A fixing block 16 is fixedly connected to the outer wall of the box 14. A rotating plate 17 is rotatably connected inside the fixing block 16. A pressing shaft 18 is fixedly connected to the outer wall of the rotating plate 17. The outer wall of the pressing shaft 18 is in contact with the outer wall of the filter plate 15. A rotating shaft 19 is rotatably connected inside the fixing block 16. A fixing plate 20 is fixedly connected to the outer wall of the rotating shaft 19. The outer wall of the rotating shaft 19 is slidably connected to the inner wall of the rotating plate 17. The outer wall of the fixing plate 20 is rotatably connected to the outer wall of the rotating plate 17. A collection box 21 is slidably connected to the inner wall of the box 14. A handle 22 is fixedly connected to the outer wall of the collection box 21.

[0018] The receiving plate 8 supports and fixes the funnel 12. The receiving plate 8, in conjunction with the funnel 12, allows for the transfer of the stirred brine. The baffle 13 slides inside the funnel 12 to prevent the brine from flowing down. The housing 14 supports and fixes the receiving plate 8. The filter plate 15 slides against the inner wall of the housing 14, filtering the brine. The housing 14 supports and fixes the fixing block 16. The rotating plate 17 rotates inside the fixing block 16, supporting and limiting its rotation. The rotating plate 17 supports and fixes the lower pressure shaft 18. When the rotating plate 17 rotates, it causes the lower pressure shaft 18 to rotate synchronously and come into contact with the outer wall of the filter plate 15. Furthermore, the rotation of the rotating plate 17 causes the rotating shaft 19 to slide into the inner wall of the rotating plate 17. The rotating shaft 19 supports and fixes the fixed plate 20. Twisting the rotating shaft 19 causes the fixed plate 20 to rotate on the outer wall of the rotating plate 17, which in turn causes the rotating plate 17 to fix the filter plate 15 through the pressing shaft 18. This allows the filter plate 15 to be replaced, and old plates that are clogged or filled with impurities can be removed and replaced in a timely manner, restoring filtration accuracy, ensuring the impurity interception effect, preventing unqualified brine from entering subsequent processes and affecting product purity, reducing the risk of impurity leakage caused by damage to old plates, reducing equipment scaling and energy consumption, and achieving the effect of maintaining the stable operation of the refining system. The collection box 21 supports and fixes the handle 22. The collection box 21 collects the filtered brine at the bottom of the device. Pulling the handle 22 causes the collection box 21 to slide on the inner wall of the box body 14, so that the filtered brine can be pulled out for subsequent use.

[0019] Example 2: Reference Figure 7 The housing 14 is internally threaded with bolts 23, and the outer wall of the bolts 23 is slidably connected to the inside of the filter plate 15. Tightening the bolts 23 moves the housing 14 through the threaded connection, allowing the bolts 23 to slide into the inside of the filter plate 15, thus enabling the replacement of the filter plate 15. This allows for the timely removal and replacement of old plates that are clogged or filled with impurities, restoring filtration accuracy, ensuring impurity retention, preventing substandard brine from entering subsequent processes and affecting product purity, reducing the risk of impurity leakage due to damage to old plates, lowering equipment scaling and energy consumption, and maintaining the stable operation of the refining system.

[0020] Working principle: During use, brine and impurities such as calcium and magnesium ions are poured into the stirring drum 1. The motor 3 on the outer wall of the fixed frame 2 is started to rotate the first bevel gear 4 at the output end. When the first bevel gear 4 rotates, it rotates the transmission rod 6 through the second bevel gear 5 connected by meshing teeth. When the transmission rod 6 rotates, it drives the first stirring blade 7 to rotate synchronously inside the device. When the first bevel gear 4 rotates, it drives the hollow tube 10 to rotate on the outer wall of the transmission rod 6 through the third bevel gear 9 connected by meshing teeth. When the hollow tube 10 rotates, it drives the second stirring blade 11 to stir in the opposite direction, realizing bidirectional stirring of brine. This breaks the eddy dead zone that is easily formed by unidirectional stirring, making the brine more uniformly mixed as a whole. It avoids the accumulation of impurities caused by uneven local concentration, ensures the stability of the purification process, and ensures that the purity of the final purified brine meets the requirements for industrial use.

[0021] After the brine is stirred, pull the baffle 13 inside the receiving tray 8 to allow the brine to enter the interior of the tank 14. The filter plate 15 will filter the brine. Pull the filter plate 15 to slide inside the tank 14 to replace the clogged filter plate 15. Lift the rotating plate 17 to rotate through the fixing block 16. When the rotating plate 17 rotates, it will press the filter plate 15 against the lower shaft 18, so that the rotation of the rotating plate 17 will cause the rotating shaft 19 and the fixing plate 20 to slide into the inner wall of the rotating plate 17. Twist the rotating shaft 19 to rotate through the fixing plate 20 to the outer wall of the rotating plate 17 to fix the replaced filter plate 15. This can promptly remove and replace the old plates that are clogged or whose pores are filled with impurities, restore the filtration accuracy, ensure the impurity interception effect, prevent unqualified brine from entering subsequent processes and affecting product purity, reduce the risk of impurity leakage caused by the damage of old plates, reduce equipment scaling and energy consumption, and achieve the effect of maintaining the stable operation of the refining system.

[0022] In practical use, this device can not only achieve bidirectional stirring of brine, breaking the dead zones of eddies that are easily formed by unidirectional stirring, making the brine more uniformly mixed, avoiding the accumulation of impurities caused by uneven local concentration, ensuring the stability of the purification process, and ensuring that the purity of the final purified brine meets the requirements for industrial use, but also replace and fix the filter plate 15. It can promptly remove and replace old plates that are blocked or whose pores are filled with impurities, restore filtration accuracy, ensure the impurity interception effect, prevent unqualified brine from entering subsequent processes and affecting product purity, reduce the risk of impurity leakage caused by damage to old plates, reduce equipment scaling and energy consumption, and achieve the effect of maintaining the stable operation of the purification system.
