Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to production wastewater treatment equipment based on ion exchange adsorption for ulinastatin production. Background Art

[0002] As a drug, ulinastatin produces wastewater during its production. For environmental protection, the wastewater usually needs to be treated before it can be discharged.

[0003] Ion exchange resin filter is a device that uses ion exchange resin to remove impurities in water. When it is used, the resin has the function of exchanging cations or anions in water. When water flows through the resin layer, the ions in the water (such as hardness ions Ca 2 +, Mg2+, etc.) will exchange with the exchangeable ions on the resin and be adsorbed and fixed by the resin. As the resin is used for a long time, the exchange sites on the resin will be occupied. At this time, the resin needs to be regenerated with salt water (for cationic resins) or other chemical solutions (for anionic resins) to restore its exchange capacity.

[0004] However, since the resin is more fully filled, it has better adsorption properties during wastewater treatment. However, during regeneration, the more full and dense resin is not conducive to the passage of the solution and sufficient contact with the resin, which makes the resin regeneration time longer.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The embodiment of the present invention provides a production wastewater treatment device based on ion exchange adsorption of ulinastatin production, such as Figure 1-12As shown, the production wastewater treatment equipment based on ion exchange adsorption for ulinastatin production includes: an upper assembly plate 1, a lower assembly plate 2, an ion exchange resin filter tank 4 and a salt solution tank 5, the upper assembly plate 1 and the lower assembly plate 2 are fixedly connected by multiple support plates 3, the upper assembly plate 1 is located directly above the lower assembly plate 2, the ion exchange resin filter tank 4 is fixedly mounted on the upper assembly plate 1 and the lower assembly plate 2, the salt solution tank 5 is fixedly mounted on the lower assembly plate 2 and is located on one side of the ion exchange resin filter tank 4; the top and bottom of the ion exchange resin filter tank 4 are both open, and the top and bottom of the ion exchange resin filter tank 4 are respectively detachably mounted with an upper tank cover 6 and a lower tank cover 7 by bolts, the top of the upper tank cover 6 is fixedly mounted with a wastewater inlet pipe 8 and a backwash drain pipe 11, and the bottom of the lower tank cover 7 is fixedly mounted with a clean water The discharge pipe 9 and the backwash liquid inlet pipe 10, the wastewater inlet pipe 8, the clean water discharge pipe 9, the backwash liquid inlet pipe 10 and the backwash discharge pipe 11 are all provided with control valves, and a liquid pump 12 is fixedly installed on the lower assembly plate 2, and the liquid inlet end of the liquid pump 12 is connected to the brine tank 5 by a suction pipe 13, and the liquid outlet end is connected to the backwash liquid inlet pipe 10 by a discharge pipe 14; a limiting support ring 15 is fixedly installed on the bottom inner wall of the ion exchange resin filter tank 4, and a lower partition 16 is placed on the top of the limiting support ring 15, and an upper partition 17 is provided above the lower partition 16, and resin is filled between the lower partition 16 and the upper partition 17, and the lower partition 16 and the upper partition 17 can slide up and down along the inner side of the ion exchange resin filter tank 4; the ion exchange resin filter tank 4 is provided with a resin backwash shaking mechanism for shaking off the resin during backwashing.

[0033] In this embodiment, when the production wastewater treatment equipment based on ion exchange adsorption for ulinastatin production of the present invention is used, the wastewater is first introduced into the ion exchange resin filter tank 4 through the wastewater inlet pipe 8, and the wastewater is subjected to ion exchange adsorption treatment by the resin filled between the lower partition 16 and the upper partition 17, and the treated clean water is discharged from the clean water discharge pipe 9.

[0034] When the resin needs to be regenerated, the brine in the brine tank 5 is extracted through the suction pipe 13 by the liquid pump 12, and is sent into the ion exchange resin filter tank 4 through the discharge pipe 14 and the backwash liquid inlet pipe 10. At the same time, the resin backwash shaking mechanism is used to shake the resin so that the brine can better contact with the resin, completing the resin regeneration process. The regenerated waste liquid is discharged through the backwash discharge pipe 11.

[0035] The present invention provides a resin backwashing and shaking mechanism to effectively shake the resin during the resin regeneration process, allowing the salt solution to pass more easily and fully contact the resin, thereby shortening the resin regeneration time, improving the resin regeneration efficiency, and reducing production costs. Furthermore, the upper tank cover 6 and the lower tank cover 7 of the ion exchange resin filter tank 4 are detachably mounted using bolts, facilitating replacement and maintenance of the resin in the filter tank.

[0036] The upper assembly plate 1 and the lower assembly plate 2 are fixedly connected via a support plate 3, forming the main frame structure of the equipment and providing a mounting base for the ion exchange resin filter tank 4 and the brine tank 5. The ion exchange resin filter tank 4 is fixedly mounted on the upper assembly plate 1 and the lower assembly plate 2. The space between the lower and upper screens 16 and 17 inside the ion exchange resin filter tank 4 is filled with resin for ion exchange adsorption treatment of wastewater. The brine tank 5 is fixedly mounted on the lower assembly plate 2 and located on one side of the ion exchange resin filter tank 4. It is connected to the ion exchange resin filter tank 4 via a liquid pump 12, a suction pipe 13, and a discharge pipe 14, providing brine for resin regeneration. The wastewater inlet pipe 8, the clean water discharge pipe 9, the backwash inlet pipe 10, and the backwash discharge pipe 11 are respectively mounted on the upper tank cover 6 and the lower tank cover 7, and are used for the introduction of wastewater, the discharge of clean water, and the backwash inlet and discharge during resin regeneration. Each pipe is equipped with a control valve to facilitate water flow control.

[0037] In a further preferred embodiment of the present invention, the resin backwashing and shaking mechanism includes a U-shaped impact frame 18 fixedly mounted on the top of the upper partition 17, and the U-shaped impact frame 18 is located just below the discharge end of the wastewater inlet pipe 8, and is used to press down the upper partition 17 when the liquid is introduced, thereby cooperating with the lower partition 16 to stabilize the resin. The top of the upper partition 17 is also fixedly mounted with an assembly support 19, and the top of the upper tank cover 6 is fixedly nested with a valve cylinder 20, and the valve cylinder 20 is located just above the assembly support 19. A guide cylinder 21 is watertightly slidably mounted in the valve cylinder 20, and a resistance disc 22 is fixedly mounted on the top of the guide cylinder 21, and the bottom A threaded column 23 is fixedly installed at the end, and the threaded column 23 is detachably connected to the assembly support 19 through a thread. A return spring 24 is sleeved on the guide cylinder 21. The bottom end of the return spring 24 conflicts with the top of the valve cylinder 20, and the top end conflicts with the bottom of the conflicting disc 22. When the wastewater inlet pipe 8 does not enter the water, the backwash liquid inlet pipe 10 is used to fill the backwash solution and rebound the upper partition 17 to increase the distance between the lower partition 16 and the upper partition 17, thereby shaking off the resin when the lower partition 16 reciprocates up and down. The resin backwash shaking mechanism also includes a reciprocating drive mechanism for driving the lower partition 16 to shake back and forth up and down.

[0038] In this embodiment, the resin backwash loosening mechanism uses a U-shaped impact frame 18 to press down on the upper screen 17 when wastewater enters the pipe 8. This, in conjunction with the lower screen 16, stabilizes the resin and prevents it from shifting under the impact of the wastewater. When wastewater enters the pipe 8 and the backwash solution is introduced into the backwash inlet pipe 10, the return spring 24 rebounds, causing the upper screen 17 to move upward, increasing the distance between the lower screen 16 and the upper screen 17. At this point, the reciprocating drive mechanism drives the lower screen 16 in an up-and-down reciprocating motion, loosening the resin particles and facilitating full contact between the backwash solution and the resin, completing the resin regeneration process.

[0039] This embodiment realizes the automatic downward pressure and rebound function of the upper partition 17 by setting a U-shaped impact frame 18 and a return spring 24, which can effectively control the stability of the resin during the entry of wastewater and backwashing, and during backwashing, by increasing the spacing between the partitions and the reciprocating shaking of the lower partition 16, the resin is shaken out, the resin regeneration efficiency is improved, the regeneration time is reduced, and at the same time, the problem of incomplete regeneration caused by resin compaction is avoided, the service life of the resin is extended, and the equipment operating cost is reduced.

[0040] A U-shaped impact frame 18 is fixedly mounted on top of the upper screen 17, directly below the discharge end of the wastewater inlet pipe 8. It is used to press down on the upper screen 17 when wastewater enters, and cooperate with the lower screen 16 to stabilize the resin. An assembly support 19 is fixedly mounted on top of the upper screen 17, and a valve cylinder 20 is fixedly nested in the top of the upper tank cover 6 and directly above the assembly support 19. A guide cylinder 21 slides watertightly within the valve cylinder 20. Its top end is fixed with a friction disc 22, and its bottom end is fixed with a threaded column 23, which is threadedly connected to the assembly support 19. A return spring 24 mounted on the guide cylinder 21 rebounds when the wastewater inlet pipe 8 is empty, causing the upper screen 17 to move upward, increasing the distance between the lower screen 16 and the upper screen 17.

[0041] In a further preferred embodiment of the present invention, the reciprocating drive mechanism includes a reciprocating lifting shaft 25 slidably mounted on the upper screen 17, the bottom end of the reciprocating lifting shaft 25 is fixedly connected to the top of the lower screen 16, the top of the reciprocating lifting shaft 25 extends to the inside of the U-shaped impact frame 18, the reciprocating lifting shaft 25 penetrates the resin, and a reciprocating power shaft 26 is rotatably mounted on the ion exchange resin filter tank 4, the reciprocating power shaft 26 penetrates the U-shaped impact frame 18 and is located directly above the reciprocating lifting shaft 25, the reciprocating power shaft 26 is arranged perpendicular to the reciprocating lifting shaft 25, and two fixed sleeves are provided on the reciprocating power shaft 26. Cam 1 27, the two cams 27 are respectively located on both sides of the reciprocating lifting shaft 25, and a track groove 28 is provided on the side where the two cams 27 are close to each other. The track groove 28 is opened along the shape of the cam 1 27, and a force-bearing cylinder 29 is installed in the two track grooves 28. The two force-bearing cylinders 29 are fixedly connected to the reciprocating lifting shaft 25. A motor 30 is fixedly installed on the upper assembly plate 1, and a sprocket 1 31 is fixedly installed on the output shaft of the motor 30 and one end of the reciprocating power shaft 26. The two sprockets 31 are provided with the same chain 32 for driving the reciprocating power shaft 26 to rotate.

[0042] In this embodiment, the reciprocating drive mechanism rotates a reciprocating power shaft 26 via a motor 30. Two cams 27 on the reciprocating power shaft 26 interact with a force-bearing cylinder 29 via a track groove 28. The force-bearing cylinder 29 is fixedly connected to the reciprocating lift shaft 25. As the reciprocating power shaft 26 rotates, the track groove 28 of the cam 27 pushes the force-bearing cylinder 29, causing the reciprocating lift shaft 25 to slide up and down within the upper screen 17. Because the bottom end of the reciprocating lift shaft 25 is fixedly connected to the lower screen 16, the lower screen 16 vibrates back and forth with the up and down motion of the reciprocating lift shaft 25, thereby loosening the resin and facilitating full contact between the backwash liquid and the resin, completing the resin regeneration process.

[0043] This embodiment sets up a reciprocating drive mechanism and uses a motor 30 to drive a cam 27 and a reciprocating lifting shaft 25 to achieve reciprocating shaking of the lower partition 16, which can effectively loosen the resin particles and avoid the compaction of the resin during long-term use, thereby improving the regeneration efficiency and adsorption performance of the resin, significantly shortening the resin regeneration time, reducing equipment operating costs, and improving wastewater treatment efficiency.

[0044] The reciprocating lifting shaft 25 is slidably mounted on the upper screen 17. Its bottom end is fixedly connected to the top of the lower screen 16, and its top extends into the interior of the U-shaped impact frame 18 and penetrates the resin. The reciprocating power shaft 26 is rotatably mounted on the ion exchange resin filter tank 4, penetrates the U-shaped impact frame 18, and is located directly above the reciprocating lifting shaft 25, arranged perpendicular to the reciprocating lifting shaft 25. Two cams 27 are fixedly mounted on the reciprocating power shaft 26. The track grooves 28 of the cams 27 are equipped with force-bearing cylinders 29, which are fixedly connected to the reciprocating lifting shaft 25. The motor 30 is fixedly mounted on the upper assembly plate 1. A sprocket 31 is mounted on its output shaft and one end of the reciprocating power shaft 26. The two sprockets 31 are connected by a chain 32, which is used to drive the reciprocating power shaft 26 to rotate, thereby achieving the reciprocating vibration of the lower screen 16.

[0045] In a further preferred embodiment of the present invention, a plurality of reinforcing ribs 33 are fixedly mounted on the bottom end of the reciprocating lifting shaft 25 , and the plurality of reinforcing ribs 33 are all fixedly connected to the lower partition net 16 .

[0046] In this embodiment, multiple reinforcing ribs 33 are fixedly mounted on the bottom end of the reciprocating lifting shaft 25 and fixedly connected to the lower screen 16, thereby enhancing the connection strength between the reciprocating lifting shaft 25 and the lower screen 16. This structural design ensures that when the reciprocating lifting shaft 25 drives the lower screen 16 to reciprocate, the lower screen 16 can stably transmit power, preventing loosening or deformation of the connection due to the weight of the resin or resistance during movement, thereby ensuring smooth resin backwashing and shaking.

[0047] In a further preferred embodiment of the present invention, a controller 34 is fixedly mounted on the upper assembly plate 1 , and the controller 34 is connected to the motor 30 and the liquid pump 12 .

[0048] In this embodiment, automated control of the wastewater treatment equipment is achieved by fixing a controller 34 on the upper assembly plate 1 and connecting the controller 34 to the motor 30 and the liquid pump 12. The controller 34 can control the start and stop and rotation speed of the motor 30 according to a preset program or operating instructions, thereby adjusting the rotation speed of the reciprocating power shaft 26 and, in turn, the reciprocating vibration frequency of the lower screen 16. Simultaneously, the controller 34 can also control the operation of the liquid pump 12, adjusting the flow rate and time of the saline solution delivery, and ensuring the smooth progress of the resin regeneration process.

[0049] In a further preferred embodiment of the present invention, the top of the U-shaped impact frame 18 is a plane, and the width of the plane is larger than the drainage end opening of the wastewater inlet pipe 8.

[0050] In this embodiment, the top of the U-shaped impact frame 18 is designed as a flat structure, and its flat width is larger than the drainage end opening of the wastewater inlet pipe 8. This design allows the wastewater discharged from the wastewater inlet pipe 8 to evenly impact the top plane of the U-shaped impact frame 18, and then transmits the impact force of the wastewater to the lower screen 16 and the upper screen 17 through the U-shaped impact frame 18, thereby stabilizing the resin layer and preventing the resin from shifting or loosening under the impact of the wastewater, ensuring the stability and reliability of the wastewater treatment process. It can also effectively disperse the impact force of the wastewater, preventing the wastewater from directly impacting the resin layer and causing the resin particles to be dispersed or damaged. This structure improves the stability of the resin layer, extends the service life of the resin, reduces the frequency of resin replacement, and reduces the operating cost of the equipment.

[0051] In a further preferred embodiment of the present invention, the assembly support 19, the valve cylinder 20, the guide cylinder 21, the abutment disc 22, the threaded column 23 and the return spring 24 are provided in multiple groups.

[0052] In this embodiment, multiple groups of assembly support 19, valve cylinder 20, guide cylinder 21, abutment disc 22, threaded column 23, and return spring 1 24 are provided. These multiple groups are evenly distributed on top of upper screen 17, allowing return spring 1 24 to more evenly rebound upper screen 17 when no wastewater enters pipe 8, thereby more effectively increasing the distance between lower screen 16 and upper screen 17 and providing more stable and uniform support for the resin's dispersion.

[0053] In a further preferred embodiment of the present invention, a through hole is provided on the upper partition net 17 for the reciprocating lifting shaft 25 to slide through.

[0054] In this embodiment, upper screen 17 is provided with a through-hole through which reciprocating shaft 25 slides. As reciprocating shaft 25 slides up and down in the through-hole, it drives lower screen 16 to move back and forth, thereby loosening the resin and ensuring that reciprocating shaft 25 is not obstructed by upper screen 17 during its movement.

[0055] In a further preferred embodiment of the present invention, the reciprocating power shaft 26 is located directly above the upper partition 17 , and both ends of the reciprocating power shaft 26 extend to the outside of the ion exchange resin filter tank 4 .

[0056] In this embodiment, reciprocating power shaft 26 is located directly above upper screen 17, with both ends extending to the exterior of ion exchange resin filter tank 4. This layout allows reciprocating power shaft 26 to be driven by an external power device (such as motor 30). Furthermore, the external extension of both ends facilitates the installation and connection of transmission components (such as sprocket 31 and chain 32), thereby achieving stable rotation of reciprocating power shaft 26. The rotation of reciprocating power shaft 26 drives cam 27, controlling the reciprocating motion of reciprocating lift shaft 25, thereby driving lower screen 16 to vibrate up and down, completing the resin loosening operation.

[0057] In a further preferred embodiment of the present invention, one end of the two force-bearing cylinders 29 located in the track groove 28 is movably embedded with balls, the balls are in contact with the inner wall of the track groove 28, and the diameter of the force-bearing cylinder 29 is equal to the opening width of the track groove 28.

[0058] In this embodiment, one end of each of the two force-bearing cylinders 29 located within the track groove 28 is movably embedded with a ball bearing, which contacts the inner wall of the track groove 28. This design effectively reduces friction when the force-bearing cylinders 29 move within the track groove 28 through the rolling contact between the ball bearings and the inner wall of the track groove 28. At the same time, the diameter of the force-bearing cylinders 29 is equal to the width of the track groove 28, ensuring that the force-bearing cylinders 29 can slide stably within the track groove 28 without loosening or getting stuck. This structural design allows the reciprocating lifting shaft 25 to reciprocate up and down more smoothly, thereby driving the lower screen 16 to achieve a stable resin shaking operation.

[0059] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments:

[0060] In another embodiment of the present invention, a brine mixing box 35 is fixedly installed on the top of the brine tank 5 for premixing brine, and a water inlet pipe 36 and a brine replenishing pipe 37 are fixedly installed at the bottom positions on both sides of the opposite sides of the brine mixing box 35. The discharge end of the brine replenishing pipe 37 is connected to the top of the brine tank 5. Valves are provided on the water inlet pipe 36 and the brine replenishing pipe 37. A salt inlet 38 is opened on the top of the brine mixing box 35, and a plurality of heating rods 39 are installed in the brine mixing box 35 for heating brine.

[0061] In this embodiment, a brine mixing box 35 is fixedly mounted on the top of the salt liquid tank 5 for premixing salt water.
