Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption technology, specifically to a heparin sodium activated carbon adsorption device. Background Technology

[0002] Sodium heparin can interfere with many aspects of the blood clotting process and 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 becoming thrombin, inhibiting thrombin, and thus preventing fibrinogen from becoming fibrin, thereby exerting an anticoagulant effect.

[0003] In the production and processing of heparin sodium, to ensure environmental safety and prevent pollution from waste liquid, the heparin sodium needs to be purified and removed. This requires the use of a heparin sodium activated carbon adsorption box. However, existing heparin sodium activated carbon adsorption box equipment not only has poor adsorption efficiency, but also often requires cumbersome disassembly, installation, and sealing work when replacing the activated carbon, increasing replacement time and labor costs. Therefore, we propose a heparin sodium activated carbon adsorption device. Utility Model Content

[0005] The technical solution of this utility model is implemented as follows: A heparin sodium activated carbon adsorption device includes a filter tank, the top of which is sealed by a first sealing cover. Inside the filter tank, a first annular support and a second annular support are coaxially connected from top to bottom, and the inner diameter of the second annular support is smaller than that of the first annular support. An activated carbon filter element is sealed between the first annular support and the second annular support. A first connecting pipe is connected to one side of the filter tank, located at the bottom of the second annular support, and a second connecting pipe is connected to the other side of the filter tank, located between the first annular support and the second annular support.

The outlet end of the second connecting pipe is connected to the suction device, and a third connecting pipe is connected to the outlet end of the suction device. The third connecting pipe passes through the second sealing cover and extends into the acid washing tank, and an exhaust pipe is connected to the second sealing cover.

[0006] Optionally, the bottom of the activated carbon filter element is coaxially connected to the first connecting seat, the first connecting seat is sealed to the top of the second annular support, and the outer diameter of the first connecting seat is smaller than the inner diameter of the first annular support.

[0009] Optionally, an annular pressure plate is coaxially connected to the bottom of the first sealing cover, and the bottom of the annular pressure plate abuts against the top of the second connecting seat.

[0010] Optionally, a check valve is fitted at one end of the third connecting pipe near the air extraction 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 Figures 1 to 3 This utility model provides a technical solution: a heparin sodium activated carbon adsorption device, including a filter tank 11, the top of the filter tank 11 is sealed by a first sealing cover 2, and a first annular support 14 and a second annular support 16 are coaxially connected from top to bottom inside the filter tank 11, and the inner diameter of the second annular support 16 is smaller than the inner diameter of the first annular support 14; and an activated carbon filter element 15 is sealed between the first annular support 14 and the second annular support 16.

[0020] like Figure 2 , 3 As shown, the bottom of the activated carbon filter element 15 is coaxially connected to the first connecting seat 3, and the first connecting seat 3 is sealed to the top of the second annular support 16. The outer diameter of the first connecting seat 3 is smaller than the inner diameter of the first annular support 14. The top of the activated carbon filter element 15 is coaxially connected to the second connecting seat 18, and the second connecting seat 18 is sealed to the top of the first annular support 14. This ensures that the top and bottom of the activated carbon filter element 15 are sealed by the first annular support 14 and the second annular support 16, respectively, so that the space formed between the activated carbon filter element 15 and the inner wall of the filter canister 11 can be used to discharge the filtered gas.

[0021] Meanwhile, to improve the sealing of the activated carbon filter element 15 connection, an annular pressure plate 13 is coaxially connected to the bottom of the first sealing cover 2. The bottom of the annular pressure plate 13 abuts against the top of the second connecting seat 18. Sealing rubber rings 17 are provided between the first connecting seat 3 and the second annular support 16, as well as between the first connecting seat 3 and the second annular support 16. Under the pressing and abutting action of the annular pressure plate 13, the sealing of the end of the activated carbon filter element 15 can be effectively guaranteed, thereby ensuring the effective filtration of gas. When replacing the activated carbon filter element 15, it can be directly pulled upwards to remove it from between the first annular support 14 and the second annular support 16, thus realizing the quick replacement of the activated carbon filter element 15.

[0022] like Figure 1 , 2 As shown, in actual use, one side of the filter tank 11 is connected to the first connecting pipe 1, and the first connecting pipe 1 is connected to the preparation equipment ( Figure 1 Connect the first connecting pipe 1 to the bottom of the second annular support 16 (as indicated by arrow A), so that the gas in the preparation equipment can be discharged into the filter tank 11 through the first connecting pipe 1 and filtered by the activated carbon filter element 15. The second connecting pipe 4 is connected to the other side of the filter tank 11. The second connecting pipe 4 is located between the first annular support 14 and the second annular support 16. The filtered gas can be discharged through the second connecting pipe 4, realizing continuous gas filtration. In order to improve the stability of the filter tank 11, multiple support legs 12 are fastened circumferentially at the bottom of the filter tank 11.

[0023] In summary, when the heparin sodium activated carbon adsorption device is in use, this utility model also includes an acid washing tank 10. The top of the acid washing tank 10 is sealed by a second sealing cover 9. An air extraction device 5 is provided on the top of the second sealing cover 9. The outlet end of the second connecting pipe 4 is connected to the air extraction device 5, and a third connecting pipe 7 is connected at the outlet end of the air extraction device 5. The third connecting pipe 7 passes through the second sealing cover 9 and extends into the acid washing tank 10.

[0024] The negative pressure of the extraction device 5 draws the gas inside the preparation equipment into the filter tank 11, where it is adsorbed by the activated carbon filter element 15. The treated gas is then transported to the pickling tank 10 through the second connecting pipe 4 and the third connecting pipe 7. Pickling solution is placed in the pickling tank 10, and the third connecting pipe 7 delivers the gas into the pickling solution, which further treats the odor in the gas, effectively improving the gas filtration efficiency. In order to prevent the pickling solution from flowing backward under the negative pressure, a one-way valve 6 is tightened at the end of the third connecting pipe 7 near the extraction device 5, and an exhaust pipe 8 is connected to the second sealing cover 9 to discharge the treated gas.

[0025] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
