Description

Technical Field

[0001] This invention belongs to the technical field of separation distillation columns, and particularly relates to a multi-group separation distillation column. Background Technology

[0002] In many fields such as chemical engineering, environmental protection, and biomedicine, distillation columns are widely used as core equipment for separating components of mixtures in processes such as solution purification, solvent recovery, and wastewater treatment. Their basic working principle is to heat the material inside the column and take advantage of the difference in boiling points of different components in the mixture to cause the low-boiling-point components to vaporize and rise, while the high-boiling-point components condense and sink, thereby achieving efficient separation of components.

[0003] However, existing conventional distillation columns have gradually revealed numerous technical defects during actual operation, restricting their separation efficiency and ease of operation and maintenance. In the heating stage, due to limitations in the internal structural design of the column, the liquid material is mostly in a relatively static or slow-flowing state. Heat can only be conducted and diffused through the column wall and the surface of the heating elements. This heat transfer method easily leads to uneven heating of the liquid in different areas of the column. Some areas of the material have reached a boiling state, while other areas remain at a low temperature. This not only disrupts the stability of the gas-liquid balance but also significantly reduces the rate of component vaporization and separation, prolonging production time. The increased cycle time and energy consumption costs are particularly pronounced when treating materials containing solid impurities, such as industrial wastewater. Industrial wastewater typically contains solid impurities such as silt, suspended particles, and residues. These impurities cannot rise with the vaporization of components during heating and will gradually settle at the bottom of the distillation column. These deposited solid impurities need to be manually cleaned or cleaned by external equipment after the distillation operation is completed. This cleaning process is not only cumbersome and time-consuming, but also seriously affects the continuous operating efficiency of the equipment. In view of this, we propose a multi-group separation distillation column. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-group separation distillation column to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a multi-group separation distillation column, comprising: A base is provided, on the top of which a distillation tank 1 is fixedly installed. A rotating rod 1 is rotatably installed inside the distillation tank 1. Several stirring blades 1 are fixedly installed around the circumference of the rotating rod 1. A heater 1 is fixedly installed at the bottom of the inner cavity of the distillation tank 1. A distillation tank 2 is fixedly installed on the top of the distillation tank 1. A rotating rod 2 is rotatably installed inside the distillation tank 2. Several stirring blades 2 are fixedly installed around the circumference of the rotating rod 2. A heater 2 is fixedly installed at the bottom of the inner cavity of the distillation tank 2. A connecting pipe is fixedly installed between the distillation tank 1 and the distillation tank 2. A drive assembly, located on the second distillation tank, is used to drive the second rotating rod and the first rotating rod to rotate. The feed hopper is fixedly installed on one side of the distillation tank 2. The feed hopper is equipped with a collection hopper. A filter screen is fixedly installed at the bottom of the collection hopper. Handles are fixedly installed on both sides of the collection hopper. Four limiting rods are fixedly installed on the collection hopper and inside the feed hopper. A limiting component is located inside the feed hopper and is used to limit the collection hopper.

[0006] In this technical solution, during use, personnel can feed wastewater into the collection hopper through the feed hopper. At this time, the wastewater will be filtered through the filter screen at the bottom of the collection hopper. The filter screen can filter out solid impurities in the wastewater, and the filtered impurities will remain in the collection hopper. After the distillation is completed, personnel can release the limit component of the collection hopper. Personnel can then remove the collection hopper from the feed hopper through two handles and clean the solid impurities remaining in the collection hopper. This ensures that solid impurities in the wastewater can be filtered before entering the first and second distillation tanks, preventing solid impurities from entering the first and second distillation tanks. This ensures that no impurities remain at the bottom of the first and second distillation tanks after distillation, eliminating the need for secondary cleaning by personnel, avoiding the trouble of manual secondary cleaning, and saving cleaning time. During distillation, personnel can activate heaters two and one, which heat the wastewater in distillation tanks two and one, respectively. Simultaneously, personnel can drive rotating rods two and one via a drive assembly. Rotating rod two causes several stirring blades two to rotate, and rotating rod one causes several stirring blades one to rotate, and so on.

[0007] The system can fully agitate the wastewater in the second distillation tank, while the rotation of several stirring blades in the first distillation tank can also fully agitate the wastewater, ensuring that the wastewater is thoroughly stirred and moderated during the heating process. This results in more uniform heating of the wastewater. The stirring action promotes efficient convection of liquid in different areas of the column, allowing heat to be quickly and evenly diffused throughout the liquid system. This effectively avoids the coexistence of local overheating and local undertemperature, significantly improves the distillation rate, shortens the overall production cycle, reduces the continuous operating time of the heating equipment, and thus reduces the energy consumption cost per unit of processing capacity.

[0008] In the above technical solution, further, the driving component includes: a first synchronous wheel, which is rotatably mounted on the top of the second distillation tank; the bottom end of the first synchronous wheel penetrates the top of the second distillation tank and is coaxially connected to the second rotating rod; a second synchronous wheel is rotatably mounted on the top of the second distillation tank and on one side of the first synchronous wheel; a synchronous belt is installed between the second synchronous wheel and the first synchronous wheel; a connecting rod is fixedly mounted on the bottom end of the second synchronous wheel; the bottom end of the connecting rod penetrates the top of the second distillation tank and the first distillation tank and is coaxially connected to the second rotating rod; a protective shell is fitted around the second synchronous wheel and the first synchronous wheel; a drive motor is fixedly mounted on the top of the protective shell; the output end of the drive motor penetrates the top of the protective shell and is coaxially connected to the second synchronous wheel.

[0009] In this technical solution, starting the drive motor causes the output shaft of the drive motor to rotate synchronous pulley one. The rotation of synchronous pulley one rotates rotating rod two, which in turn rotates several stirring blades two. Simultaneously, the rotation of synchronous pulley one also drives the synchronous belt, which in turn drives synchronous pulley two to rotate. The rotation of synchronous pulley two then drives the connecting rod to rotate, which in turn drives rotating rod one. The rotation of rotating rod one then drives several stirring blades one. The rotation of these stirring blades two effectively agitates the wastewater in the distillation tank two, ensuring thorough agitation and tempering of the wastewater during heating. This results in more uniform heating of the wastewater. The agitation promotes efficient convection in different areas of the column, allowing heat to spread rapidly and evenly throughout the liquid system. This effectively avoids the coexistence of localized overheating and underheating, significantly improving the distillation rate, shortening the overall production cycle, and reducing the continuous operation of heating equipment.

[0010] This reduces time, thereby lowering the energy cost per unit of processing volume.

[0011] In the above technical solution, the protective shell is further welded tightly to the distillation tank, and the output shaft of the drive motor is rotatably connected to the protective shell.

[0012] In this technical solution, the structural stability of the protective shell and the distillation tank is ensured, and the output shaft of the drive motor can rotate normally inside the protective shell.

[0013] In the above technical solution, the limiting component further includes: a sliding groove, the sliding groove being opened in the feeding hopper, limiting blocks being symmetrically slidably installed in the sliding groove, a limiting hole being opened at the top of the collecting hopper, the top end of the limiting block penetrating the limiting hole, a fixing plate being fixedly installed in the sliding groove and located between the two limiting blocks, and guide rods being fixedly installed on both sides of the fixing plate, with springs sleeved on the guide rods.

[0014] In this technical solution, pressing the two limiting blocks brings them closer together. This close proximity compresses two springs, causing them to contract until the tops of both limiting blocks are inside the limiting holes. At this point, the limiting blocks release the collection hopper, allowing personnel to remove it from the feed hopper using the two handles. Any remaining solid impurities in the collection hopper can then be cleaned. This ensures that solid impurities in the wastewater are filtered before entering distillation tanks one and two, preventing them from entering these tanks. This ensures that no impurities remain at the bottom of distillation tanks one and two after distillation, eliminating the need for secondary cleaning and saving time.

[0015] In the above technical solution, the top end of the limiting block is engaged with the limiting hole, the top end of the limiting block has an inclined structure, and the two ends of the spring are respectively tightly welded to the fixing plate and the limiting block.

[0016] In this technical solution, it is ensured that the top of the limiting block can be engaged in the limiting hole, thus ensuring the structural stability of the limiting block and the spring.

[0017] Furthermore, the above technical solution also includes: two collection boxes, both of which are fixedly installed on the top of the base and respectively located at the distillation...

[0018] On one side of the first distillation tank and the second distillation tank, a conveying pipe is fixedly installed on one side of the second distillation tank, the bottom end of the conveying pipe extends into one of the collection tanks, a conveying pipe is fixedly installed on one side of the first distillation tank, the bottom end of the conveying pipe extends into another collection tank, and a discharge pipe is fixedly installed on one side of the collection tank.

[0019] In this technical solution, the liquids after distillation in distillation tank 1 and distillation tank 2 will enter two collection tanks through delivery pipe 2 and delivery pipe 1 respectively for collection. With the cooperation of distillation tank 1 and distillation tank 2, a multi-group separation effect can be achieved, making the distillation effect and rate better.

[0020] In the above technical solution, the top of the inner cavity of both the first distillation tank and the second distillation tank is inclined, and the first stirring blades are distributed in a ring at equal intervals, and the second stirring blades are distributed in a ring at equal intervals.

[0021] In this technical solution, it is ensured that the distilled water at the top of the inner cavity of distillation tank 1 and distillation tank 2 can flow into delivery pipe 2 and delivery pipe 1 respectively, ensuring that the distribution of several stirring blades 1 and several stirring blades 2 is uniform.

[0022] In the above technical solution, the limiting rod is further configured to be inserted into the feed hopper.

[0023] In this technical solution, it is ensured that the limiting rod can be inserted into the feed hopper.

[0024] The beneficial effects of this invention are as follows: 1. This multi-group separation distillation column, through the setting of several stirring blades II and several stirring blades I, continuously and uniformly stirs the liquid material during the heating process, breaking the single heat transfer mode of traditional distillation columns that rely on heat conduction. The stirring action promotes efficient convection of liquid in different areas of the column, so that heat can be quickly and uniformly diffused to the entire liquid system, effectively avoiding the phenomenon of local overheating and local low temperature coexisting. This improvement can not only quickly establish a stable gas-liquid equilibrium environment, accelerate the vaporization and separation process of low boiling point components, and significantly improve the distillation rate, but also shorten the overall production cycle, reduce the continuous operation time of heating equipment, and thus reduce the energy consumption cost per unit processing volume.

[0025] 2. This multi-unit separation distillation column, through its collection hopper and filter screen, and with the cooperation of limiting components, ensures that solid impurities in the wastewater are filtered before entering distillation tank one and distillation tank two, preventing solid impurities from entering distillation tank one and distillation tank two, and ensuring the safety of distillation tank one.

[0026] After distillation, no impurities remain at the bottom of the second distillation tank, eliminating the need for secondary cleaning and saving time.

[0027] 3. This multi-unit separation distillation column, with its uniform heating effect provided by the stirring mechanism, avoids thermal stress damage to the column body and internal components caused by excessive local temperature differences, thus slowing down the aging process of the equipment. The reduced difficulty in cleaning solid impurities decreases wear and corrosion on the heating elements and gas-liquid contact components within the column, further extending the overall service life of the equipment. Furthermore, the improved heating uniformity and reduced impurity residue jointly ensure the stability of the gas-liquid balance during distillation, reducing the interference of impurities on component separation, effectively improving the purity and separation accuracy of the distillation products, and meeting higher production standards.

[0037] Example 1: Please refer to Figures 1-10. This embodiment provides a multi-unit separation distillation column, including: a base 1, a distillation tank 2 fixedly installed on the top of the base 1, a rotating rod 3 rotatably installed inside the distillation tank 2, several stirring blades 4 fixedly installed around the rotating rod 3, a heater 5 fixedly installed at the bottom of the inner cavity of the distillation tank 2, a distillation tank 6 fixedly installed on the top of the distillation tank 2, a rotating rod 7 rotatably installed inside the distillation tank 6, several stirring blades 8 fixedly installed around the rotating rod 7, a heater 9 fixedly installed at the bottom of the inner cavity of the distillation tank 6, and a connecting pipe 27 fixedly installed between the distillation tank 2 and the distillation tank 6. The drive assembly, located on the distillation tank 26, is used to drive the rotating rod 27 and rotate...

[0038] Rod 3 rotates; Feed hopper 16 is fixedly installed on one side of distillation tank 2 6. A collection hopper 17 is provided inside the feed hopper 16. A filter screen 18 is fixedly installed at the bottom of the collection hopper 17. Handles 19 are fixedly installed on both sides of the collection hopper 17. Four limiting rods 20 are fixedly installed on the collection hopper 17 and inside the feed hopper 16. A limiting component is located inside the feed hopper 16 and is used to limit the collection hopper 17.

[0039] In operation, wastewater is fed into the collection hopper 17 through the feed hopper 16. The wastewater is then filtered through the filter screen 18 at the bottom of the collection hopper 17, which removes solid impurities. These impurities remain in the collection hopper 17. After distillation, the collection hopper 17 can be released from its limit position using the limiting component. The collection hopper 17 can then be removed from the feed hopper 16 using the two handles 19. Any remaining solid impurities in the collection hopper 17 can then be cleaned. This ensures that solid impurities in the wastewater are filtered before entering the first and second distillation tanks 2 and 6, preventing them from entering these tanks. This ensures that no impurities remain at the bottom of the first and second distillation tanks 2 after distillation, eliminating the need for secondary cleaning and saving time. During distillation, personnel can activate heaters 2 (9) and 5 (5), which heat the wastewater in distillation tanks 2 (6) and 2 (2), respectively. Simultaneously, personnel can drive rotating rods 2 (7) and 3 (3) via a drive assembly. Rotating rod 2 (7) drives several stirring blades 2 (8), and rotating rod 3 drives several stirring blades 4 (4). The rotation of stirring blades 2 (8) thoroughly stirs the wastewater in distillation tank 2 (6), while the rotation of stirring blades 4 (4) thoroughly stirs the wastewater in distillation tank 2 (2). This ensures thorough stirring and gentle heating of the wastewater during the heating process, resulting in more uniform heating. The stirring action promotes efficient convection in different areas of the column, allowing heat to spread quickly and evenly throughout the liquid system. This effectively avoids the coexistence of localized overheating and underheating, significantly improving the distillation rate, shortening the overall production cycle, reducing the continuous operating time of heating equipment, and thus lowering the energy cost per unit processing volume.

[0040] Example 2: This embodiment provides a multi-group separation distillation column. In addition to the technical solutions of the above embodiments, it also has the following technical features: the driving component includes: a synchronous pulley 10, which is rotatably mounted on the top of the distillation tank 2 6. The bottom end of the synchronous pulley 10 passes through the top of the distillation tank 2 6 and is coaxially connected to the rotating rod 2 7. A synchronous pulley 21 is rotatably mounted on the top of the distillation tank 2 6 and on one side of the synchronous pulley 10. A synchronous belt 12 is installed between the synchronous pulley 21 and the synchronous pulley 10. A connecting rod 13 is fixedly mounted on the bottom end of the synchronous pulley 21. The bottom end of the connecting rod 13 passes through the top of the distillation tank 2 6 and the distillation tank 2 1 2 and is coaxially connected to the rotating rod 3. A protective shell 14 is sleeved around the synchronous pulley 21 and the synchronous pulley 10. A drive motor 15 is fixedly mounted on the top of the protective shell 14. The output end of the drive motor 15 passes through the top of the protective shell 14 and is coaxially connected to the synchronous pulley 10.

[0041] When the drive motor 15 is started, its output shaft drives the synchronous pulley 10 to rotate. The rotation of the synchronous pulley 10 drives the rotating rod 7 to rotate, which in turn drives several stirring blades 8 to rotate. Simultaneously, the rotation of the synchronous pulley 10 also drives the synchronous belt 12, which in turn drives the synchronous pulley 11 to rotate. The rotation of the synchronous pulley 11 drives the connecting rod 13 to rotate, which in turn drives the rotating rod 3 to rotate. The rotation of the rotating rod 3 drives several stirring blades 4 to rotate. The rotation of the stirring blades 8 effectively agitates the wastewater in the distillation tank 26, while the rotation of the stirring blades 4 effectively agitates the wastewater in the distillation tank 26. The wastewater inside the tower is thoroughly stirred to ensure that it is adequately stirred and softened during the heating process, resulting in more uniform heating. The stirring action promotes efficient convection in different areas of the liquid within the tower, allowing heat to spread quickly and evenly throughout the entire liquid system. This effectively avoids the coexistence of local overheating and local underheating, significantly improves the distillation rate, shortens the overall production cycle, reduces the continuous operating time of the heating equipment, and thus lowers the energy consumption cost per unit of processing capacity.

[0042] Example 3: This embodiment provides a multi-group separation distillation column, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the protective shell 14 is tightly welded to the distillation tank 6, and the output shaft of the drive motor 15 is rotatably connected to the protective shell 14.

[0043] This ensures the structural stability of the protective shell 14 and the distillation tank 6, and guarantees that the output shaft of the drive motor 15 can rotate normally within the protective shell 14.

[0044] Example 4: This embodiment provides a multi-group separation distillation column. In addition to the technical solutions of the above embodiments, it also has the following technical features: the limiting component includes a sliding groove 22, which is opened in the feed hopper 16. Limiting blocks 26 are symmetrically slidably installed in the sliding groove 22. A limiting hole 21 is opened at the top of the collecting hopper 17. The top of the limiting block 26 passes through the limiting hole 21. A fixing plate 23 is fixedly installed in the sliding groove 22 and between the two limiting blocks 26. Guide rods 24 are fixedly installed on both sides of the fixing plate 23. Springs 25 are sleeved on the guide rods 24.

[0045] Pressing the two limiting blocks 26 brings them closer together, causing them to compress the two springs 25 until the tops of both limiting blocks 26 are inside the limiting holes 21. At this point, the two limiting blocks 26 release the collection hopper 17, allowing personnel to remove it from the feed hopper 16 using the two handles 19. This allows for the cleaning of any remaining solid impurities in the collection hopper 17, ensuring that solid impurities in the wastewater are filtered before entering the first and second distillation tanks 2 and 6. This prevents solid impurities from entering the first and second distillation tanks 2 and 6, ensuring that no impurities remain at the bottom of the first and second distillation tanks 2 and 6 after distillation, eliminating the need for secondary cleaning and saving time.

[0046] Example 5: This embodiment provides a multi-group separation distillation column, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the top end of the limiting block 26 is engaged with the limiting hole 21, the top end of the limiting block 26 has an inclined structure, and the two ends of the spring 25 are respectively tightly welded to the fixing plate 23 and the limiting block 26.

[0047] Specifically, it is ensured that the top of the limiting block 26 can be inserted into the limiting hole 21, thus ensuring the structural stability of the limiting block 26 and the spring 25.

[0048] Example 6: This embodiment provides a multi-group separation distillation column. In addition to the technical solutions of the above embodiments, it also has the following technical features, including: two collection boxes 30, both collection boxes 30 are fixedly installed on the top of the base 1 and are respectively located on one side of distillation box 1 2 and distillation box 2 6. A conveying pipe 1 28 is fixedly installed on one side of distillation box 2 6, and the bottom end of the conveying pipe 1 28 extends into one of the collection boxes 30. A conveying pipe 2 29 is fixedly installed on one side of distillation box 1 2, and the bottom end of the conveying pipe 2 29 extends into the other collection box 30. A discharge pipe 31 is fixedly installed on one side of the collection box 30.

[0049] The liquids after distillation in distillation tank 1 2 and distillation tank 2 6 will enter two collection tanks 30 through conveying pipe 2 29 and conveying pipe 1 28 respectively for collection. With the cooperation of distillation tank 1 2 and distillation tank 2 6, a multi-group separation effect can be achieved, making the distillation effect and rate better.

[0050] Example 7: This embodiment provides a multi-group separation distillation column, which, in addition to the technical solution of the above embodiment, also has the following technical features: the top of the inner cavity of distillation tank 1 2 and distillation tank 2 6 are both inclined, a number of stirring blades 1 4 are distributed in a ring at equal intervals, and a number of stirring blades 2 8 are distributed in a ring at equal intervals.

[0051] Specifically, it ensures that the distilled water at the top of the inner cavity of distillation tank 12 and distillation tank 26 can flow into the delivery pipe 29 and delivery pipe 128 respectively, and ensures that the distribution of the stirring blades 14 and 28 is uniform.

[0052] Example 8: This embodiment provides a multi-group separation distillation column, which, in addition to the technical solution of the above embodiment, also has the following technical features: the limiting rod 20 is inserted into the feed hopper 16.

[0053] Among them, it is ensured that the limit rod 20 can be inserted into the feed hopper 16.

[0054] Working Principle: During use, wastewater is fed into the collection hopper 17 through the feed hopper 16. The wastewater is then filtered through the filter screen 18 at the bottom of the collection hopper 17, which removes solid impurities. These impurities remain in the collection hopper 17. After distillation, the operator presses the two limiting blocks 26, bringing them closer together. This close contact compresses the two springs 25, causing them to contract until the tops of both limiting blocks 26 are inside the limiting holes 21. At this point, the limiting blocks 26 release the collection hopper 17, allowing the operator to remove it from the feed hopper 16 using the two handles 19. The remaining solid impurities in the collection hopper 17 are then cleaned, ensuring that solid impurities in the wastewater are filtered before entering the first and second distillation tanks 2 and 6, thus preventing them from entering and ensuring the smooth operation of the first distillation tank. The distillation tank 26 leaves no impurities at the bottom after distillation, eliminating the need for secondary cleaning and saving time. During distillation, personnel can activate heaters 9 and 5, which heat the wastewater in distillation tanks 6 and 2, respectively. Simultaneously, personnel can activate drive motor 15. The output shaft of drive motor 15 drives synchronous pulley 10 to rotate. The rotation of synchronous pulley 10 drives rotating rod 7, which in turn drives several stirring blades 8. Simultaneously, the rotation of synchronous pulley 10 also drives synchronous belt 12, which in turn drives synchronous pulley 11 to rotate. The rotation of synchronous pulley 11 drives connecting rod 13, which in turn drives rotating rod 3. The rotation of rotating rod 3 drives several stirring blades 4. The rotation of stirring blades 8 thoroughly stirs the wastewater in distillation tank 6, while the rotation of stirring blades 4 stirs the wastewater in distillation tank 2. The wastewater inside the column is thoroughly stirred to ensure that it is adequately agitated and moderated during the heating process. This results in more uniform heating of the wastewater. The stirring action promotes efficient convection in different areas of the liquid within the column, allowing heat to be rapidly and evenly distributed throughout the entire liquid system. This effectively avoids the coexistence of localized overheating and underheating, significantly improving the distillation rate and shortening the overall distillation time.

[0055] Reduce the production cycle and shorten the continuous operating time of heating equipment, thereby reducing the energy consumption cost per unit of processing volume; After distillation in distillation tank 1 2 and distillation tank 2 6, the liquids will enter two collection tanks 30 through delivery pipe 2 29 and delivery pipe 1 28 respectively for collection. With the cooperation of distillation tank 1 2 and distillation tank 2 6, a multi-group separation effect can be achieved, making the distillation effect and rate better.
