A heparin sodium filtration membrane assembly capable of precipitation treatment

Abstract

This invention discloses a heparin sodium filtration membrane assembly capable of precipitation, comprising a precipitation chamber, a drain outlet, and a filtration assembly. The drain outlet is located below the precipitation chamber for discharging liquid. The filtration assembly is disposed inside the precipitation chamber and includes a mounting frame, a fixing plate, a support plate, a connecting plate, a lateral filter enclosure, a movable filter plate, a filter belt, a movable roller, and the mounting plate. The mounting frame is secured above the precipitation chamber. This heparin sodium filtration membrane assembly capable of precipitation can shield the outside of the precipitate through the lateral filter enclosure and the movable filter plate. Then, by moving the mounting plate upward, the filter belt and precipitate move upward, and the liquid is discharged through the lateral filter enclosure and the movable filter plate. This allows the precipitate to be processed separately without draining the liquid in the precipitation chamber. Subsequently, opening the movable filter plate and moving the filter belt automatically carries the precipitate out, thus achieving the treatment of the precipitate.

Description

Technical Field

[0001] This invention relates to the field of heparin sodium preparation technology, specifically to a heparin sodium filtration membrane assembly capable of precipitation. Background Technology

[0002] Heparin sodium, as an anticoagulant, is commonly used in medicine. It is generally prepared through chemical synthesis. In the precipitation process of heparin sodium preparation, after the semi-finished heparin sodium is formed in the precipitation tank, it needs to be separated from the water on top. This separation can be achieved by filtration to remove the liquid from the precipitate, or by extraction. For example, a heparin sodium precipitation filter tank disclosed in application number CN202120460497.0 on October 22, 2021, is designed with a tank body and a top cover for easy maintenance and processing. A lifting mechanism is installed on the top cover. The device uses a pull rod to lift and lower the filter head and the flexible bellows, thereby solving the problem of wastewater discharge in the sedimentation separation tank. A heparin sodium filtration device disclosed in application number CN201520852164.7 on April 20, 2016, can significantly improve the product yield. It adopts a structure in which the drain pipe is distributed from top to bottom, which allows the waste liquid to be discharged naturally from the drain pipe, while the heparin sodium solution remains at the bottom of the tank, thereby preventing the loss of effective product. The long and short stirring blades of the agitator are distributed at intervals to fully mix the liquid before perfect filtration and sedimentation. The inclined bottom outlet can maximize the collection of heparin sodium, and the transparent window can be used to observe the situation inside the tank.

[0003] While current filtration membrane modules or filtration units can filter liquids, the filtered sediment remains on the filtration unit, making subsequent collection inconvenient. Cleaning the sediment can easily cause contamination. Furthermore, with traditional filtration methods, the liquid must be drained to remove the sediment. If the liquid needs to be reused later, the removed liquid needs to be temporarily stored and then added back into the equipment, reducing the convenience of subsequent sediment treatment and the ease of liquid reuse. Summary of the Invention

[0004] The purpose of this invention is to provide a heparin sodium filtration membrane assembly capable of precipitation treatment, in order to solve the problems mentioned above. Although the filtration membrane assemblies or filtration assemblies currently used can filter liquids, the precipitates remain on the filtration assembly after filtration, making subsequent collection inconvenient. Cleaning the precipitates can easily cause contamination. Furthermore, with traditional filtration methods, the liquid must be drained to remove the precipitates. If the liquid needs to be reused later, the removed liquid needs to be temporarily stored and then added back into the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heparin sodium filtration membrane assembly capable of precipitation, comprising a precipitation chamber, a drain outlet, and a filtration assembly. The drain outlet is located below the precipitation chamber for discharging liquid. The filtration assembly is disposed inside the precipitation chamber. The filtration assembly includes a mounting frame, a fixing plate, a support plate, a connecting plate, a lateral filter enclosure, a movable filter plate, a filter belt, a movable roller, and the mounting plate. The mounting frame is secured above the precipitation chamber, and a fixing plate is fixed above the mounting frame. A support plate extends through the interior of the fixing plate, and a connecting plate is fixed below the support plate. A lateral filter enclosure is fixed below the connecting plate to shield the precipitate. A movable filter plate is located on the left side of the lateral filter enclosure, and the movable filter plate and the lateral filter enclosure form a sliding structure. A mounting plate is fixed below the lateral filter enclosure, and a movable roller is rotatably mounted on the inner side of the mounting plate. A filter belt is connected to the surface of the movable roller, providing support for the precipitate through the filter belt and allowing the precipitate to pass through the movable roller. The rotation drives the filter belt to move, carrying out sediment. A drive shaft is connected to the front of the movable roller, providing rotational power. A transmission mechanism is located on the outer side of the mounting frame, connecting to the drive shaft to control its rotation after the mounting plate rises. A guide plate is located below the movable filter plate, with a control shaft fixed to its end. The guide plate is rotatably connected to the mounting plate via the control shaft. A rotation control mechanism is located behind the control shaft, allowing the control shaft to rotate and extend the guide plate to guide the sediment after the mounting plate moves upward. A first magnetic block is fixed to the outer side of the movable filter plate, and a second magnetic block is fixed above the fixed plate.

[0012] To further optimize this technical solution, sliders are fixed at both the front and rear ends of the movable filter plate. The sliders and the lateral filter enclosure form an up-and-down sliding structure.

A power supply mechanism is provided on the outside of the rotating shaft to provide rotational power to the rotating shaft. A stirring shaft is provided on the outside of the rotating shaft, and a fixed shaft is fixed to the inner end of the stirring shaft. The fixed shaft and the rotating shaft are rotatably connected, and a torsion spring is installed at the end of the fixed shaft. A storage groove is opened on the surface of the rotating shaft to store the rotating stirring shaft.

[0024] To further optimize this technical solution, the power supply mechanism includes a second gear, a transmission block, a connecting groove, a third gear, and a second motor.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] (1) The heparin sodium filter membrane module that can be settled can shield the outside of the precipitate through the side filter enclosure and the movable filter plate. Then, by moving the mounting plate upward, the filter belt and the precipitate move upward. The liquid is discharged through the side filter enclosure and the movable filter plate, so that the subsequent precipitate can be treated separately without the need to discharge the liquid in the sedimentation chamber. Afterward, the movable filter plate is opened, and the precipitate is automatically carried out by the movement of the filter belt, thereby realizing the treatment of the precipitate, reducing the possibility of the precipitate being contaminated, and improving the convenience of subsequent precipitate collection.

[0032] (2) After the mounting plate rises, the heparin sodium filter membrane assembly can provide feeding guidance for the precipitate under the filter belt through the rotation of the guide plate, so that it can be smoothly discharged from the sedimentation chamber and collected on the outside of the sedimentation chamber. The side filter enclosure is installed above the sedimentation chamber through the mounting frame and the fixing plate, which makes subsequent installation and disassembly convenient and also facilitates the enclosure of the filter belt and other structures.

[0033] (3) The heparin sodium filter membrane assembly that can be settled can stir the liquid in the settling chamber by rotating the rotating shaft in conjunction with the stirring shaft, thereby accelerating the reaction. When the subsequent mounting plate rises, the stirring shaft is squeezed and can rotate and be stored in the storage tank, so that the rotating shaft can move smoothly up and down with the mounting plate.

A filter belt 9 is connected to the surface of the movable roller 10, providing support for the sediment. The rotation of the movable roller 10 drives the filter belt 9 to move, carrying the sediment out. A drive shaft 12 is connected to the front of the movable roller 10, providing rotational power. A transmission mechanism is provided on the outer side of the mounting frame 3, connecting to the drive shaft 12 after the mounting plate 11 rises to control the rotation of the drive shaft 12. A guide plate 13 is provided below the mounting plate 11, located below the movable filter plate 8, and a control shaft 1 is fixed to the end of the guide plate 13. 5. The guide plate 13 is rotatably connected to the mounting plate 11 via the control shaft 15. A rotation control mechanism is provided on the rear side of the control shaft 15. After the mounting plate 11 moves upward, the control shaft 15 can rotate, causing the guide plate 13 to extend and guide the sediment. A first magnetic block 21 is fixed to the outer side of the movable filter plate 8, and a second magnetic block 22 is fixed above the fixed plate 4. The second magnetic block 22 and the first magnetic block 21 are arranged with opposite magnetic poles facing each other. The movable filter plate 8 is moved by the attraction of the second magnetic block 22 to the first magnetic block 21. A through groove 23 is provided inside the fixed plate 4 to provide movement space for the movable filter plate 8. A movement control mechanism is connected above the support plate 5 to control the movement of the support plate 5 and the connecting plate 6. The lateral filter enclosure 7 and the movable filter plate 8 are also connected. The outer side of the filter plate 8 is attached to the inner wall of the sedimentation chamber 1, allowing the sediment to fall above the filter belt 9. A cleaning brush 14 is installed above the guide plate 13 and is mounted on the inner side of the mounting plate 11 to clean the surface of the filter belt 9, ensuring that the sediment falls completely above the guide plate 13. Slider 19s are fixed at both the front and rear ends of the movable filter plate 8. The slider 19 and the side filter enclosure 7 form an up-and-down sliding structure, and a second spring 20 is connected above the slider 19 to provide a downward pushing force to keep the movable filter plate 8 stable. The transmission mechanism includes an output shaft 24, a first motor 25, an auxiliary block 38, an adsorption magnet 39, a telescopic block 40, and a third spring 41. The output shaft 24 is located on the front side of the mounting frame 3, and the first motor 25...The output shaft 24 is connected to and controls its rotation. An auxiliary block 38 is fixed to the front of the mounting bracket 3. The output shaft 24 is rotatably mounted on the rear of the auxiliary block 38. An adsorption magnet 39 is located on the rear of the output shaft 24, with its center coinciding with the center of the rising transmission shaft 12. The front end of the transmission shaft 12 is made of magnetic material, attracting the adsorption magnet 39. The rear of the adsorption magnet 39 is made of rubber. A telescopic block 40 is fixed to the front of the adsorption magnet 39 and is positioned inside the output shaft 24, forming a front-to-back telescopic structure. A third spring 41 is located on the outside of the telescopic block 40, providing forward thrust. The movement control mechanism includes a fourth gear 36 and a third motor 37. The fourth gear 36 is rotatably mounted inside the fixed plate 4, and a meshing connection is formed between the fourth gear 36 and the support plate 5. The third motor 37 is connected to the fourth gear 36 to control its rotation.

[0047] In use, the mounting bracket 3 can be placed above the sedimentation chamber 1, allowing the filter belt 9 to enter the bottom of the sedimentation chamber 1. Then, reagents are added to the sedimentation chamber 1 to react and generate precipitate. The precipitate will fall along the side filter enclosure 7 and the movable filter plate 8 onto the surface of the filter belt 9. After the precipitate is fully generated, the fourth gear 36 can be rotated by the third motor 37. The fourth gear 36, through meshing with the support plate 5, drives the support plate 5 to move. The support plate 5, through the connecting plate 6, drives the side filter enclosure 7, the movable filter plate 8, and the mounting plate 11 upwards, carrying the precipitate upwards. Simultaneously, the liquid will enter the sedimentation chamber 1 along the side filter enclosure 7 and the movable filter plate 8. When the mounting plate 11 rises above the sedimentation chamber 1, the second magnetic block 22 engages with the first magnetic block 2. 1. The suction causes the movable filter plate 8 to move upward, opening the left side of the lateral filter enclosure 7. Simultaneously, the drive shaft 12 moves to a position opposite to the output shaft 24. The drive shaft 12 and the adsorption magnet 39 attract each other, causing them to adhere to each other. This moves the telescopic block 40. Then, the output shaft 24 can be rotated by the first motor 25. The output shaft 24 drives the adsorption magnet 39 to rotate. The adsorption magnet 39, through friction with the drive shaft 12, drives the drive shaft 12 to rotate, causing the movable roller 10 to rotate. This moves the filter belt 9, sending out the sediment. The cleaning brush 14 helps prevent sediment from sticking to the filter belt 9. Afterward, the mounting plate 11 and the filter belt 9 can be lowered back into the sedimentation chamber 1 for continued use of the liquid and continued collection and treatment of sediment.

[0048] The rotation control mechanism includes a first gear 16, a drive plate 17, and a first spring 18. The first gear 16 is fixed to the rear end of the control shaft 15. The drive plate 17 and the first gear 16 are meshed together. The drive plate 17 is located inside the mounting plate 11 and forms an up-and-down sliding structure with the mounting plate 11. The upper end of the drive plate 17 penetrates the upper surface of the lateral filter enclosure 7. The first spring 18 is located on the outside of the drive plate 17 to provide an upward pushing and restoring force for the drive plate 17. When the mounting plate 11 moves upward, the drive plate 17 is squeezed by the fixed plate 4, which can control the first gear 16 to rotate.

[0049] When the mounting plate 11 moves above the sedimentation chamber 1, the drive plate 17 and the fixed plate 4 come into contact. The fixed plate 4 pushes the drive plate 17 to move, causing the drive plate 17 to drive the first gear 16 to rotate. The first gear 16 drives the guide plate 13 to rotate through the control shaft 15, causing the guide plate 13 to rotate outward at an angle to guide the sediment sent out on the filter belt 9 so that it can be smoothly discharged from the sedimentation chamber 1 for easy collection.

[0050] A rotating shaft 26 is rotatably mounted on the upper end of the connecting plate 6, and the upper end of the rotating shaft 26 passes through the fixed plate 4 to form a sliding structure. A power supply mechanism is provided on the outer side of the rotating shaft 26 to provide rotational power to the rotating shaft 26. A stirring shaft 27 is provided on the outer side of the rotating shaft 26, and a fixed shaft 28 is fixed to the inner end of the stirring shaft 27. The fixed shaft 28 and the rotating shaft 26 are rotatably connected, and a torsion spring 29 is installed at the end of the fixed shaft 28. A storage groove 30 is formed on the surface of the rotating shaft 26 to store the rotating stirring shaft 27. The power supply mechanism includes... The system comprises a second gear 31, a transmission block 32, a connecting groove 33, a third gear 34, and a second motor 35. The second gear 31 is sleeved on the outside of the rotating shaft 26 and is rotatably mounted inside the fixed plate 4. The transmission block 32 is fixed on the inside of the second gear 31. The connecting groove 33 is formed on the surface of the rotating shaft 26 and forms an up-and-down sliding structure with the transmission block 32. The third gear 34 is set on the outside of the second gear 31 and forms a meshing connection with the second gear 31. The second motor 35 is connected to the third gear 34 to control the rotation of the third gear 34.

[0051] During the liquid reaction, the third gear 34 can be rotated by the second motor 35. The third gear 34 drives the second gear 31 to rotate through the meshing of the second gear 31. The second gear 31 drives the rotating shaft 26 to rotate through the transmission block 32, causing the stirring shaft 27 to rotate and stir the liquid. When the mounting plate 11 moves upward, the rotating shaft 26 moves upward synchronously. The transmission block 32 slides in the connecting groove 33. When the stirring shaft 27 moves to the fixed plate 4, it will be squeezed by the fixed plate 4 and drive the fixed shaft 28 to rotate, so that the stirring shaft 27 can enter the interior of the receiving groove 30, so that it can pass smoothly through the second gear 31. Subsequently, the stirring shaft 27 can be automatically rotated out by the torsion spring 29.
