Description

Technical Field

[0001] This utility model relates to the field of heparin sodium processing technology, and in particular to a rapid precipitation separation device for heparin sodium processing. Background Technology

[0002] A heparin sodium separation unit is a device used to extract heparin sodium from biological materials (such as intestinal mucosa). It operates primarily through a series of physical and chemical separation methods. It includes a filtration unit to remove impurities and an ion exchange column for adsorbing and separating heparin sodium components. This device can precisely control reaction conditions, such as temperature and pH, effectively improving the purity and extraction efficiency of heparin sodium, playing a crucial role in the industrial production of heparin sodium.

[0003] The heparin sodium separation unit mainly consists of a feeding system, a separation unit, and a control system. The feeding system transports raw materials containing heparin sodium. The separation unit is the core component, including a filtration device to intercept large particulate impurities; an ion exchange resin column to adsorb heparin sodium; and an elution device to separate the heparin sodium. The control system precisely regulates parameters such as flow rate, temperature, and pH. The working principle is that after the raw material enters, it undergoes filtration, adsorption, and elution steps, utilizing differences in physical and chemical properties to separate the heparin sodium from the raw material.

[0004] In existing technologies, some heparin sodium separation devices still use traditional bolt fixing, which makes it impossible to quickly install and disassemble the filter cartridge. When the filter cartridge and other components inside the filter cartridge need to be replaced, the inability to quickly install and disassemble them will greatly increase the time and cost of maintenance and repair, while also reducing overall production efficiency and increasing production costs. Therefore, a rapid precipitation separation device for heparin sodium processing is proposed to solve the above problems. Utility Model Content

Due to the characteristics of the second spring, the scraper will rebound when it scrapes stubborn impurities. The scraper will squeeze the second spring through the sliding plate to reset the scraper and remove stubborn impurities, reducing the risk of blockage and protecting the filter barrel.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a rapid precipitation separation device for heparin sodium processing, comprising a separation tank 1, which serves as the main structure of the entire device, providing a mounting base and accommodating space for internal components. A filter tank 2 is fixedly connected to the inner wall of the separation tank 1. The filter tank 2 performs preliminary filtration of the precipitation during heparin sodium processing, separating impurities from the target substance. A housing 3 is fixedly connected to the outside of the filter tank 2, protecting the internal transmission and other related components and enabling them to operate in a relatively stable environment. A transmission column 4 is rotatably connected to the inner wall of the housing 3, transmitting the rotational force of an external knob 5 to the interior, driving the corresponding components to move. A knob 5 is fixedly connected to the outside of the transmission column 4, allowing for convenient external application of operating force by rotating the knob 5. A gear 6 is fixedly connected to the end of the transmission column 4 away from the knob 5, serving as a key component of the transmission, converting rotational motion into linear motion to drive other components. A locking pin 8 is slidably connected to the inner wall of the housing 3, fixing the position of the filter tank 2 and ensuring its stability during normal operation.

[0033] The external fixed connection of the locking post 8 is a rack plate 7, which cooperates with the gear 6 to realize the transmission of force and the conversion of motion. The gear 6 and the rack plate 7 are meshed. The external fixed connection of the housing 3 is a protective cover 9, which further protects the internal moving parts and prevents external factors from interfering with their normal operation. The inner wall of the protective cover 9 is slidably connected to a limit plate 10, which limits the range of motion of the fixed post 11 and other parts. The external fixed connection of the limit plate 10 is a fixed post 11, which connects the pull post 12 and the limit plate 10 and plays a key role in the transmission of force. The end of the fixed post 11 away from the limit plate 10 is fixedly connected to a pull post 12, which allows the operator to apply pulling force from the outside to perform corresponding operations. The external fixed connection of the fixed post 11 is a spring 13, which uses its elasticity to realize the reset of the parts and provide a certain buffering effect during operation. The external fixed connection of the separation tank 1 is a drive assembly that drives the subsequent parts.

[0034] Reference Figure 2 and Figure 4 The drive assembly includes a motor 14, which serves as a power source to provide power for the operation of the entire device, enabling it to actively perform operations such as separating sediment. A rotating column 15 is fixedly connected to the drive end of the motor 14. The rotating column 15 transmits the rotational power of the motor 14 to other connected components. Multiple fixing rods 16 are fixedly connected to the outside of the rotating column 15. The fixing rods 16 can enhance the connection stability between the rotating column 15 and the limiting sleeve 17 and transmit the rotational force. Two limiting sleeves 17 are fixedly connected to the ends of the multiple fixing rods 16 away from the rotating column 15. The limiting sleeves 17 restrict the range of motion of components such as the slide plate 18, ensuring that the scraper 19 can work in the appropriate position.

[0035] The inner walls of the two limiting sleeves 17 are slidably connected to slide plates 18. The slide plates 18 move the scraper 19 within a certain range to scrape different positions on the inner wall of the filter barrel 2. The scraper 19 is fixedly connected to the outside of the slide plates 18. The scraper 19 directly contacts the inner wall of the filter barrel 2 and can scrape off the more stubborn impurities attached to the inner wall of the filter barrel 2, ensuring that the filtration effect of the filter barrel 2 remains good. Multiple springs 20 are fixedly connected to the end of the slide plates 18 away from the scraper 19. The springs 20 use their elasticity to make the scraper 19 rebound when it scrapes stubborn impurities, preventing the scraper 19 from being damaged due to excessive resistance. At the same time, it can also allow the scraper 19 to return smoothly after completing the scraping action. The motor 14 is fixedly connected to the outside of the separation barrel 1.

[0036] Reference Figure 3The gear 6 is externally rotatably connected to the inner wall of the housing 3. This rotatable connection allows the gear 6 to rotate smoothly within the housing 3, stably transmitting the rotational force from the knob 5. The rack plate 7 is externally slidably connected to the inner wall of the housing 3. This sliding connection ensures that the rack plate 7 moves linearly within the housing 3 according to the drive of the gear 6, thereby driving the locking pin 8 to complete the corresponding action. The end of the fixed pin 11 away from the pull pin 12 is in contact with the inner wall of the housing 3. This contact method ensures that the fixed pin 11 has a stable support point when under force, making the entire operation process more stable. The spring 13 is externally fixedly connected to the outside of the limiting plate 10, allowing the spring 13 to fit tightly with the limiting plate 10. When the limiting plate 10 moves, the spring 13 can accurately exert its elastic effect.

[0037] One end of spring 13, away from the limiting plate 10, is fixedly connected to the inner wall of the protective cover 9. This connection determines the installation position of spring 13, allowing it to extend and retract within the space defined by the protective cover 9 to achieve the corresponding function. The outer part of spring 13 is slidably connected to the inner wall of the protective cover 9. This sliding connection avoids unnecessary obstruction during the extension and retraction of spring 13, ensuring its smooth operation. The outer part of the fixing post 11 is slidably connected to the inner wall of the locking post 8. This sliding connection allows the fixing post 11 to move flexibly in and out of the locking post 8, enabling control of the position of the locking post 8. The outer part of the pull post 12 is in contact with the outer part of the protective cover 9, making it convenient for the operator to grasp the pull post 12 from the outside for lifting operations, and ensuring that the pull post 12 has a stable position reference during operation.

[0038] Reference Figure 2 and Figure 4 The end of scraper 19 furthest from slide plate 18 contacts the inner wall of filter barrel 2. This close contact ensures that scraper 19 can effectively scrape away stubborn impurities on the inner wall of filter barrel 2, maintaining the good filtration performance of filter barrel 2. The end of spring 20 furthest from slide plate 18 is fixedly connected to the inner wall of limiting sleeve 17. This connection allows spring 20 to accurately provide rebound and reset force to slide plate 18 and scraper 19 with limiting sleeve 17 as support. The external rotating column 15 is rotatably connected to the inner wall of filter barrel 2. This rotatable connection allows rotating column 15 to rotate stably inside filter barrel 2, smoothly transmitting the power of motor 14. The movable locking column 8 is movably connected to the inner wall of separation barrel 1. This movable connection ensures that locking column 8 can perform corresponding movement operations inside separation barrel 1, thereby realizing the function of fixing and disassembling filter barrel 2.

[0039] Working Principle: In the operation of the equipment, when it is necessary to disassemble and replace the filter cartridge 2, first pull up the pull column 12. The pull column 12 will drive the fixed column 11 connected to it. As the fixed column 11 moves upward, it will act on the limiting plate 10, causing it to move upward as well, and will also compress the internal spring 13. As the fixed column 11 moves upward, it will disengage from the inside of the retaining column 8. Next, rotate the knob 5. The knob 5 drives the transmission column 4 to rotate, which in turn drives the gear 6 to start rotating. When the gear 6 rotates, it will drive the rack plate 7 to move, thereby causing the retaining column 8 to move out of the inside of the separation cartridge 1. At this point, the fixing device of the filter cartridge 2 is released, and it can be disassembled and replaced.

[0040] When the motor 14 is started, the rotating column 15 begins to rotate, driving the fixed rod 16, which in turn acts on the limiting sleeve 17. Because the second spring 20 is elastic, when the scraper 19 scrapes stubborn impurities, the second spring 20 causes the scraper 19 to rebound. Specifically, the scraper 19 is pressed against the second spring 20 by the sliding plate 18, and then the rebound force of the second spring 20 allows the scraper 19 to return to its original position, thus effectively removing stubborn impurities while preventing damage to the filter cartridge 2 and protecting it.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
