[0002] Sodium heparin can interfere with many aspects of the blood clotting process and has anticoagulant effects both in vivo and in vitro. The production of sodium heparin requires steps such as raw material processing, oxidation, precipitation, dissolution, and freeze drying.
[0003] Currently, during precipitation, the feed solution needs to be filtered and transferred to a precipitation tank, alcohol is added, and the mixture is stirred thoroughly. The tank is then allowed to stand and sealed to settle, and the precipitate is collected. Most current technologies separate the precipitate by retaining the heparin sodium precipitate. However, because the precipitate is newly settled and not yet stable, the extraction efficiency is affected. Therefore, we propose a heparin sodium precipitation solution draining device.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. 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 skilled in the art without creative effort are within the protection scope of this utility model.
[0019] Reference Figs. 1 to 3 This utility model provides a technical solution: a heparin sodium precipitation solution draining device, including a precipitation tank 3, with a feed pipe 2 connected to the upper end of the outer wall of the precipitation tank 3 and a discharge pipe 4 connected to the lower end of the outer wall of the precipitation tank 3, as shown below. Fig. 2 As shown, an observation port 15 is provided on the side wall of the sedimentation tank 3 to facilitate observation of the sedimentation of raw materials in the sedimentation tank 3, thereby facilitating the extraction of the upper liquid inside. The top of the sedimentation tank 3 is sealed by the tank cover 1. The tank cover 1 is rotatably connected to the fixing seat 19, and the fixing seat 19 is coaxially provided with the support tube 8 threadedly connected to it. The top of the tank cover 1 is fastened with a second motor 6. The output end of the second motor 6 and the outer wall of the fixing seat 19 are both connected with gears 7, which are meshed with each other. The second motor 6 drives the gears 7 to rotate, and under the meshing action, the support tube 8 can be raised and lowered and slid on the tank cover 1.
[0020] like Fig. 2 , 3 As shown, a connecting seat 17 is tightly fastened to the bottom of the support pipe 8 located in the sedimentation tank 3, and a protective mesh cover 18 is set at the bottom of the connecting seat 17. The end of the support pipe 8 extends into the protective mesh cover 18. In order to achieve stable lifting and sliding of the support pipe 8, a guide rod 25 penetrating the tank cover 1 is vertically connected to the top of the connecting seat 17. When the support pipe 8 lifts and slides, it can push the protective mesh cover 18 and the bottom of the support pipe 8 to move into the upper layer of liquid after stratification. Under the isolation and filtration effect of the protective mesh cover 18, the sediment is prevented from flowing into the support pipe 8, thereby ensuring the full extraction of the upper layer of liquid.
[0021] This utility model also includes a collection tank 12. The top of the support pipe 8 is connected to the pump body 10 through a hose 9. A transport pipe 21 is connected to the outlet of the pump body 10, and the other end of the transport pipe 21 extends into the collection tank 12. The top of the collection tank 12 is sealed by a top cover 11, and the pump body 10 is fastened to the top of the top cover 11. The transport pipe 21 is installed through the top cover 11. A filter screen 24 is installed in the collection tank 12. The filter screen 24 is located below the transport pipe 21. The upper liquid after being drawn by the support pipe 8 is discharged into the collection tank 12 through the transport pipe 21 and flows through the filter screen 24. Under the filtering action of the filter screen 24, the upper liquid can be filtered again to ensure the purity of the upper liquid after being drawn.
[0022] likeFig. 3 As shown, to improve the stability of the filter screen 24 placed in the liquid collection tank 12, a limiting seat 23 is coaxially connected to the inner wall of the liquid collection tank 12, a support seat 22 is coaxially connected to the top of the filter screen 24, and the support seat 22 is coaxially placed on the limiting seat 23. An outlet pipe 14 is connected to the bottom of the liquid collection tank 12. The upper liquid after secondary filtration can be transported through the outlet pipe 14. In order to improve the stability of the device, multiple support legs 13 are fastened circumferentially at the bottom of the liquid collection tank 12.
[0023] In summary, the heparin sodium precipitation solution draining device has a rotating shaft 16 rotatably connected to the tank cover 1, extending into the precipitation tank 3, and several stirring rods 20 fastened to the lower outer wall of the shaft 16. The top of the rotating shaft 16 extends above the tank cover 1 and is fixedly connected to a first motor 5. The first motor 5 drives the rotating shaft 16 to rotate, and drives the stirring rods 20 to stir the raw material inside the precipitation tank 3. The stirred raw material can then be precipitated. The operator can observe the precipitation situation inside the precipitation tank 3 in real time through the observation port 15.
[0024] Simultaneously, the second motor 6 drives the support pipe 8 to slide downwards, causing the protective mesh cover 18 and the bottom of the support pipe 8 to come into contact with the upper layer solution. Under the action of the pump body 10, the upper layer liquid is quickly extracted and transported to the collection tank 12. The separation and filtration effect of the protective mesh cover 18 and the filter screen 24 can prevent the sediment at the bottom from being sucked into the collection tank 12, thereby ensuring the purity of the extracted upper layer solution. In actual use, solenoid valves are connected to the feed pipe 2, discharge pipe 4 and liquid outlet pipe 14, which can effectively control the transportation of the upper layer liquid and internal raw materials, bringing great convenience to the operators.
