Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wastewater treatment equipment, and in particular to a waste liquid treatment device for heparin sodium production. Background Technology
[0002] Heparin sodium is a widely used anticoagulant drug, derived from the sodium salt of sulfated aminoglucan extracted from the intestinal mucosa of pigs. Wastewater generated during heparin sodium production mainly originates from extraction, purification, and refining processes. This wastewater contains high concentrations of organic matter, salts, and residual drug components; direct discharge without treatment will pollute the environment. Therefore, proper treatment of heparin sodium production wastewater is crucial.
[0003] Currently, the treatment of heparin sodium production wastewater typically employs a combination of physical, chemical, and biological methods. Physical methods such as sedimentation, filtration, and adsorption remove most suspended solids and impurities; chemical methods such as oxidation-reduction and neutralization further degrade organic matter and adjust pH; finally, biological treatment methods such as microbial degradation convert harmful substances in the wastewater into harmless substances, achieving compliant discharge or reuse.
[0004] In existing technologies, when physical methods are used to remove impurities, a large amount of flocculant is deposited at the bottom of the waste liquid pool after the impurities are adsorbed. It is difficult to replace and clean the substance that adsorbs the impurities, and the waste liquid needs to be extracted and the treatment container replaced for subsequent waste liquid cleaning. This requires a lot of manpower and resources and makes the treatment process complicated. Therefore, a waste liquid treatment device for heparin sodium production is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a waste liquid treatment device for heparin sodium production, which aims to improve the problem in the prior art where the deposition of flocculants makes it difficult to clean the bottom of the waste liquid pool and requires frequent replacement of treatment containers for subsequent treatment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A waste liquid treatment device for heparin sodium production includes a treatment tank. A purification box is slidably connected to the inner wall of the treatment tank. A filter plate is detachably connected to the inner wall of the purification box. A cylinder is installed on the outside of the treatment tank. A connecting plate is rotatably connected to the inner wall of the purification box. A rotating block is rotatably connected to the inner wall of the connecting plate. The driving end of the cylinder is fixedly connected to the bottom of the rotating block. A connecting rod is movably connected to the inner wall of the purification box. The other end of the connecting rod is movably connected to the inner wall of the connecting plate. An anti-backflow component is installed on the inner wall of the treatment tank to prevent backflow during the transport of purified water.
[0008] As a further description of the above technical solution:
[0009] The anti-backflow assembly includes a connecting pipe, the outside of which is fixedly connected to the inner wall of the treatment tank. A spring is fixedly connected to the inner wall of the connecting pipe, and a fixing pipe is fixedly connected to the outside of the connecting pipe.
[0010] As a further description of the above technical solution:
[0011] A fixing block is fixedly connected to the top of the linkage rod, and the outside of the linkage rod is slidably connected to the inner wall of the filter plate.
[0012] As a further description of the above technical solution:
[0013] The fixed tube is slidably connected to the outside of a rotating tube, the rotating tube is threadedly connected to the inner wall of a threaded tube, and the threaded tube is slidably connected to the inner wall of an intermediate tube.
[0014] As a further description of the above technical solution:
[0015] A conveying pipe is fixedly connected to the inner wall of the threaded pipe, and a small ball is movably connected to the inner wall of the threaded pipe.
[0016] As a further description of the above technical solution:
[0017] A second spring is fixedly connected to the inner wall of the conveying pipe, and the outer side of the second ball is in contact with the other end of the second spring.
[0018] As a further description of the above technical solution:
[0019] A small ball is movably connected to the inner wall of the fixed tube, and the outside of the small ball is in contact with the other end of the spring.
[0020] As a further description of the above technical solution:
[0021] The intermediate tube is fixedly connected to the outside of multiple intermediate blocks, and the other end of the intermediate tube is slidably connected to the inner wall of the fixed tube.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the lifting and lowering of the linkage rod drives the lifting and lowering of the purification box, which in turn drives the lifting and lowering of the filter plate, thereby enabling the operator to easily replace the purification material inside the purification box. This device allows for easier separation of purified water after waste liquid treatment, ensuring that the treated water is purer.
[0024] 2. In this utility model, a passage is formed between the second ball, the intermediate tube, and the first ball, allowing the liquid to flow. By twisting the rotating tube, the positional relationship is stabilized. The threaded tube is removed, and the first spring pushes the first ball into close contact with the inner wall of the fixed tube, thus preventing liquid leakage. This ensures that the treated water quality remains at a high standard and avoids the re-entry of pollutants into the purification component due to backflow. Attached Figure Description

[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 Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a wastewater treatment device for heparin sodium production, comprising a treatment tank 1, a purification box 5 slidably connected to the inner wall of the treatment tank 1, and the outer side of the purification box 5 fitting against the inner wall of the treatment tank 1, allowing the purification box 5 to slide freely inside the treatment tank 1, thereby ensuring that the purification box 5 can fully contact the wastewater to be treated. A filter plate 6 is detachably connected to the inner wall of the purification box 5, used to filter larger particles. The interior of the purification box 5 contains flocculants and other substances used for physical adsorption. A cylinder 2 is installed on the outside of the treatment tank 1, and a connecting plate 4 is rotatably connected to the inner wall of the purification box 5. A rotating block 3 (as shown in the attached figure) is rotatably connected to the inner wall of the connecting plate 4. Figure 4 The position change of the rotating block 3 causes the position of the connecting plate 4 to change.
[0033] The drive end of cylinder 2 is fixedly connected to the bottom of rotating block 3. Activating cylinder 2 causes the position of the drive end of cylinder 2 to change, thus changing the position of rotating block 3. The other end of the linkage rod 7 is movably connected to the inner wall of the linkage plate 4 (as shown in the attached diagram). Figure 2 The positional change of the linkage plate 4 causes the positional change of the linkage rod 7, mainly upward and downward. The inner wall of the purification box 5 is movably connected to the linkage rod 7, and the positional change of the linkage rod 7 causes the purification box 5 to rise or fall. A fixing block 8 is fixedly connected to the top of the linkage rod 7, ensuring that the other end of the linkage rod 7 does not detach from the position of the linkage plate 4 during movement. The outer surface of the linkage rod 7 is slidably connected to the inner wall of the filter plate 6 (as shown in the attached diagram). Figure 1 The position change of the linkage 7 causes the position change of the filter plate 6.
[0034] Reference Figure 1 and Figure 3 The inner wall of the treatment tank 1 is equipped with an anti-backflow component to prevent the purified water from flowing back. The anti-backflow component includes a connecting pipe 9, which is externally fixed to the inner wall of the treatment tank 1 (as shown in the attached figure). Figure 1 A spring 11 is fixedly connected to the inner wall of the connecting pipe 9, so that one end of the spring 11 is fixed in position during deformation. A fixing pipe 10 is fixedly connected to the outside of the connecting pipe 9, and the connecting pipe 9 fixes the position of the fixing pipe 10. A rotating pipe 14 is slidably connected to the outside of the fixing pipe 10, and the fixing pipe 10 fixes the position of a section of the rotating pipe 14. A threaded pipe 15 is threadedly connected to the inner wall of the rotating pipe 14. After the position of the threaded pipe 15 is fixed, turning the rotating pipe 14 allows the inner wall of the rotating pipe 14 to rotate outside the threaded pipe 15, thereby fixing the positions of the rotating pipe 14 and the threaded pipe 15.
[0035] An intermediate pipe 13 is slidably connected to the inner wall of the threaded pipe 15; the positional change of the threaded pipe 15 causes the positional change of the intermediate pipe 13. A conveying pipe 17 is fixedly connected to the inner wall of the threaded pipe 15; the positional change of the threaded pipe 15 causes the positional change of the conveying pipe 17. A small ball 16 (as shown in the attached figure) is movably connected to the inner wall of the threaded pipe 15. Figure 3 The intermediate tube 13 pushes the first ball 12, and the first ball 12 pushes the intermediate tube 13 in the opposite direction, causing the intermediate tube 13 to push the second ball 16 to move. A second spring 18 is fixedly connected to the inner wall of the conveying tube 17, and the outer side of the second ball 16 is in contact with the other end of the second spring 18 (as shown in the attached diagram). Figure 3 The positional change of the small ball 16 causes the spring 18 to deform, thereby the spring 18 returns to its original position and pushes the position of the small ball 16 to stabilize the position of the intermediate tube 13, so that the liquid can flow from the gap between the intermediate tube 13 and the small ball 16.
[0036] The other end of the intermediate tube 13 is slidably connected to the inner wall of the fixed tube 10. A small ball 12 is movably connected to the inner wall of the fixed tube 10. The positional change of the intermediate tube 13 can cause the position of the small ball 12 to change. The outside of the small ball 12 is in contact with the other end of the spring 11. The positional change of the small ball 12 causes the spring 11 to deform. The return of the spring 11 causes the small ball 12 to make tight contact with the intermediate tube 13, so that the liquid can only flow from the notch of the intermediate tube 13. A plurality of intermediate blocks 19 are fixedly connected to the outside of the intermediate tube 13. The intermediate blocks 19 are used to ensure that the position of the intermediate tube 13 is limited by the position of the threaded tube 15 and the fixed tube 10 when the connection relationship is not fixed.
[0037] Working principle: When cylinder 2 is started, the position change of the drive end of cylinder 2 causes the position change of rotating block 3, which manifests as lifting and lowering in the longitudinal direction. The rotation of rotating block 3 adapts to changes in angle tilt. The lifting and lowering of rotating block 3 causes the other end of connecting plate 4 to change in the opposite position. The position change of connecting plate 4 causes connecting rod 7 to slide laterally or longitudinally on the inner wall of connecting plate 4. Due to the limiting effect of fixed block 8, connecting rod 7 is lifted and lowered, thereby driving the lifting and lowering of purification box 5 and filter plate 6. This allows the operator to easily replace the purification material inside purification box 5. This device allows for easier separation of purified water after waste liquid treatment, ensuring that the treated water quality is purer. The replaceability and easy cleaning of the purification material box makes maintenance simple.
[0038] The position of the moving threaded tube 15 causes the position of the conveying tube 17 to change. The position change of the threaded tube 15 causes the position of the intermediate tube 13 to change. The intermediate tube 13 pushes the position of the small ball 12 to change. The position change of the small ball 12 causes the spring 11 to deform. The return of the spring 11 pushes the other end of the small ball 12 to make full contact with the outside of the intermediate tube 13, thereby pushing the position of the intermediate tube 13 to change. This allows the intermediate tube 13 to push the position of the second small ball 16 to change. The position change of the second small ball 16 causes the second spring 18 to deform. The return of the spring 18 causes the second small ball 16 to change. The ball 12 is in close contact with the outside of the intermediate tube 13, thus forming a passage between the ball 16, the intermediate tube 13, and the ball 12, allowing the liquid to flow. The rotating tube 14 is turned to stabilize its position. The threaded tube 15 is removed, and the spring 11 pushes the ball 12 into close contact with the inner wall of the fixed tube 10, thus preventing liquid leakage. This ensures that the treated water quality is always maintained at a high standard, avoiding backflow that could cause pollutants to re-enter the purification system and affect the efficiency and effectiveness of the entire wastewater treatment process. The anti-backflow measures also improve the stability and reliability of the equipment.
[0039] 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.
