Description

Technical Field

[0001] This utility model relates to the technical field of heparin sodium production equipment, specifically to a layered feeding heparin sodium production eluent tank. Background Technology

[0002] Heparin sodium is an anticoagulant that interferes with many aspects of the blood clotting process. It has anticoagulant effects both in vivo and in vitro. Its mechanism of action is relatively complex. It mainly works by binding to antithrombin III, thereby enhancing the latter's inhibitory effect on activated coagulation factors II, IX, X, XI, and XII. The consequences include preventing platelet aggregation and destruction, hindering the formation of coagulation-activating enzymes, preventing prothrombin from converting into thrombin, and inhibiting thrombin, thus exerting an anticoagulant effect.

[0003] When washing heparin sodium, elution tanks are often used. While existing elution tanks can achieve basic elution functions, their stirring blades are mostly fixed and spatially arranged in a relatively static position, making dynamic adjustment by moving them up and down impossible. Since there are inevitably gaps between the stirring blades, this static and gapped stirring mode directly leads to difficulties in achieving a uniform mixing state between the heparin sodium raw material and the eluent. Poor mixing uniformity during elution will trigger a series of chain reactions, most notably severely affecting elution efficiency and making it difficult to achieve the ideal extraction rate of heparin sodium. Therefore, improvements are needed. Utility Model Content

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1 to 7 As shown, this utility model provides a layered feeding eluent for the production of heparin sodium, including a support rod 1. A ring 2 is fixedly connected to the top of the support rod 1. An eluent body 3 is fixedly sleeved on the inner surface of the ring 2. A stirring motor 4 is movably installed at the middle of the top of the eluent body 3. A stirring shaft 5 is fixedly sleeved at the other end of the output shaft of the stirring motor 4. The bottom of the stirring shaft 5 penetrates through the eluent body 3 and extends into the interior of the eluent body 3, and a stirring blade 6 is fixedly connected thereto. A stirring blade located at the top of the eluent body 3 is fixedly connected to the stirring motor 4. The rear pneumatic cylinder 7 has a first round shaft 8 fixedly connected to its top. A rotating plate 9 is movably connected to the outer surface of the first round shaft 8. A movable shaft 10 is movably sleeved in the middle of the rotating plate 9. A fixed rod 11 is fixedly sleeved on the outer surface of the movable shaft 10. The bottom of the fixed rod 11 is fixedly connected to the top of the washing tank body 3. A second round shaft 12 is movably connected to the inner surface of the other end of the rotating plate 9. A fixed plate 13 is fixedly connected to the other end of the second round shaft 12. The bottom of the fixed plate 13 is fixedly connected to the top of the stirring motor 4.

[0029] When the pneumatic cylinder 7 is running, it will drive the first circular shaft 8 to move downward, which in turn causes the rotating plate 9 to rotate around the movable shaft 10 as the axis, driving the second circular shaft 12 and the fixed plate 13 to move upward, thereby causing the stirring motor 4 to move upward as a whole. At the same time, the stirring motor 4 starts, which will cause the stirring shaft 5 to drive the stirring blade 6 to rotate. With the up and down movement of the stirring blade 6, the raw materials and eluent are mixed more evenly.

[0030] The washing tank body 3 has an inlet 14 fixedly connected to the left side of the top, and a first cover plate 15 is hinged to the top of the inlet 14. A first handle 16 is fixedly connected to the top of the first cover plate 15.

[0031] Pulling the first handle 16 causes the first cover plate 15 to rotate, which will release the sealing effect on the top of the feed inlet 14, making it easier for the operator to add heparin sodium raw material.

[0032] The inner surface of the washing tank body 3 is fixedly fitted with a cylinder 17, and the cylinder 17 has a circular hole 18 inside.

[0033] This design allows the detergent inside the cylinder 17 to be discharged into the washing tank body 3 through the round hole 18.

[0034] The top of the cylinder 17 is hinged to a second cover plate 19, and the top of the second cover plate 19 is fixedly connected to a second handle 20.

[0035] Pulling the second handle 20 causes the second cover plate 19 to rotate, releasing the sealing effect on the top of the cylinder 17, thus making it easier for the operator to add eluent to the inside of the cylinder 17.

[0036] The cylinder 17 has a movable sleeve 21 inside, and a pull rod 22 is fixedly connected to the outer surface of the movable sleeve 21. The outer surface of the pull rod 22 is movably connected to the inner surface of the cylinder 17, and a through hole 23 is opened inside the movable sleeve 21.

[0037] Pull the lever 22 to rotate until the through hole 23 is aligned with the round hole 18, which will release the sealing effect on the round hole 18. At this time, the detergent inside the cylinder 17 will flow from the round hole 18 and the through hole 23 into the interior of the washing tank body 3, achieving the purpose of layered feeding.

[0038] Among them, a valve 24 is fixedly installed at the bottom of the washing tank body 3, and a discharge pipe 25 is fixedly connected to the bottom of the valve 24.

[0039] Opening valve 24 will allow the heparin sodium feedstock inside the eluent tank 3 to be discharged through discharge pipe 25.

[0040] The discharge pipe 25 has a filter screen 26 installed inside it, and the filter screen 26 is circular in appearance.

[0041] The filter screen 26 is designed to filter impurities in the heparin sodium raw material.

[0042] Among them, a drive motor 27 is fixedly connected to the bottom of the back of the washing tank body 3, and a rotating shaft 28 is fixedly sleeved at the other end of the output shaft of the drive motor 27. A rectangular plate 29 is fixedly sleeved on the outer surface of the rotating shaft 28.

[0043] When the drive motor 27 is running, it will cause the rotating shaft 28 to drive the rectangular plate 29 to rotate.

[0044] Among them, the top and bottom of the front of the rectangular plate 29 are hinged with connecting rods 30, and the other end of the connecting rods 30 is hinged with a movable plate 31. The inner side of the movable plate 31 is fixedly connected with round rods 32. There are two round rods 32. The inner sides of the two round rods 32 pass through the discharge pipe 25 and the filter screen plate 26 in sequence and extend into the interior of the filter screen plate 26.

[0045] The two connecting rods 30 rotate, causing the two movable plates 31 to move in opposite directions, which in turn causes the two round rods 32 to move in opposite directions. When the two round rods 32 move to the outside of the filter screen plate 26, the fixing effect on the filter screen plate 26 will be released. At this time, the filter screen plate 26 can be pulled down to achieve the purpose of quickly disassembling the filter screen plate 26.

[0046] There are four support rods 1, all of the same size, and the four support rods 1 are symmetrical about the center of the ring 2.

[0047] The design of four support rods 1 provides a more stable support effect for the ring 2.

[0048] Working principle and usage process of this utility model:

[0049] When eluting heparin sodium raw material, firstly, pull the first handle 16 to rotate the first cover plate 15 to release the sealing effect on the feed port 14. Then, pour the heparin sodium raw material into the eluent tank body 3 through the feed port 14. Next, open the second cover plate 19 to release the sealing effect on the top of the cylinder 17. Then, pour the eluent into the cylinder 17. At this time, pull the lever 22 to rotate until the through hole 23 is aligned with the round hole 18, which will release the sealing effect on the round hole 18. Then, the detergent inside the cylinder 17 will flow from the round hole 18 and the through hole 23 into the eluent tank body 3, achieving the purpose of layered feeding.

[0050] After the material is added, the stirring motor 4 is started, which will cause the stirring shaft 5 to drive the stirring blades 6 to rotate, mixing the raw material with the eluent. At the same time, the pneumatic cylinder 7 is started, which will drive the first circular shaft 8 to move downward, thereby causing the rotating plate 9 to rotate around the movable shaft 10 as the axis, driving the second circular shaft 12 and the fixed plate 13 to move upward, thus causing the stirring motor 4 to move upward as a whole. With the up and down movement of the stirring blades 6 and the rotation stirring, the raw material and the eluent are mixed more evenly. When the heparin sodium raw material is washed out, the valve 24 is opened, so that the heparin sodium raw material inside the eluent tank body 3 is filtered through the filter screen plate 26 and discharged to the outside through the discharge pipe 25.

[0051] When a large amount of impurities are adsorbed inside the filter screen plate 26, the drive motor 27 is started, which will cause the rotating shaft 28 to drive the rectangular plate 29 to rotate. This will cause the two connecting rods 30 to rotate, causing the two movable plates 31 to move in opposite directions. Consequently, the two round rods 32 will move in opposite directions. When the two round rods 32 move to the outside of the filter screen plate 26, the fixing effect on the filter screen plate 26 will be released. At this time, the filter screen plate 26 can be pulled down to achieve the purpose of quickly disassembling and replacing the filter screen plate 26.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
