Description

Technical Field

[0001] The present invention belongs to the technical field of raw material extrusion, and relates to a raw material extrusion device for heparin sodium production. Background Art

[0002] Heparin sodium can interfere with many links of the blood coagulation process and has anticoagulant effects both in vivo and in vitro. Its mechanism of action is relatively complex. It mainly binds to antithrombin III (AT-III), thereby enhancing the inhibitory effect of the latter on activated coagulation factors II, IX, X, XI, and XII. The consequences involve preventing platelet aggregation and destruction, interfering with the formation of thrombin activator, preventing prothrombin from becoming thrombin, inhibiting thrombin, and thus interfering with the conversion of fibrinogen into fibrin, thereby exerting an anticoagulant effect.

[0003] When preparing heparin sodium, small intestinal mucosa needs to be used, and heparin sodium can be obtained after treatment. During the treatment process, the raw materials need to be dried, and before drying, the water or other liquids in the raw materials need to be extruded to improve the drying efficiency.

A limit frame 11 is fixedly connected inside the first mounting port. A filter plate 12 is movably connected inside the limit frame 11. A positioning frame for positioning the filter plate 12 is fixed on the inner wall of the limit frame 11 to prevent the filter plate 12 from falling. A jacking mechanism 15 for improving the filtering effect is provided at the bottom of the filter plate 12. A second mounting port is opened at the top of the pressing box 2. A feeding hopper 5 is fixedly connected to the top of the second mounting port. The feeding hopper 5 can temporarily store raw materials. A vibration mechanism 10 for preventing the feeding hopper 5 from being blocked is provided on one side of the feeding hopper 5. An adjusting mechanism for adjusting the feeding speed of the feeding hopper 5 is provided on one side of the feeding hopper 5. A third mounting port is opened on one side of the pressing box 2. A discharging mechanism 3 for discharging materials is provided inside the third mounting port. The discharging mechanism 3 includes a gantry 25. The gantry 25 is fixedly connected between the outer walls on both sides of the pressing box 2. Sliding channels are opened on both sides of the gantry 25. A sliding plate 26 and a blocking plate 28 are slidably connected between the two sliding channels. The blocking plate 28 is located inside the third mounting port. Two first tension springs 27 are fixedly connected between the sliding plate 26 and the blocking plate 28. The first tension springs 27 are used to pull the blocking plate 28 so that the blocking plate 28 can only be opened when there is pressure. An adjusting component for adjusting the position of the sliding plate 26 is provided on the top of the gantry 25. Anti-blocking mechanisms 18 for preventing blockage during feeding are provided on both sides of the pressing box 2. Two fixing plates 13 are fixedly connected to the outer wall of the bottom of the pressing box 2. A water collecting hopper 14 is fixedly connected between the two fixing plates 13. The extruded liquid can be collected through the water collecting hopper 14. A support plate 16 is fixedly connected between the two sides of the chassis 1. A collecting hopper 17 is provided on the upper surface of the support plate 16. The collecting hopper 17 is used to collect the raw materials after extrusion.

[0043] In the present invention, the anti-blocking mechanism 18 includes two guiding blocks 19 which are respectively fixedly connected to the outer walls on both sides of the extrusion box 2. A driving frame 20 running through is slidably connected in each of the two guiding blocks 19. One end of each driving frame 20 is fixed to the pressing plate 8, and the other end of each driving frame 20 is fixedly connected to a push rod 21. The other end of each push rod 21 is fixedly connected to a guide rail 22. An inserting frame 24 is slidably connected between the two guide rails 22. The driving frame 20 can push the guide rail 22 to move through the push rod 21, thereby driving the inserting frame 24 to push out the extruded raw materials, avoiding the raw materials staying on the blocking plate 28. A spring 23 is fixedly connected to the inner wall on one side of each of the two guide rails 22, and the other end of each of the two springs 23 is fixed to the inserting frame 24. The spring 23 provides a buffer space for the movement of the inserting frame 24 to avoid the inserting frame 24 coming into hard contact with the blocking plate 28. The adjusting component is a first threaded rod 29. The first threaded rod 29 rotatably penetrates through the top of the gantry 25, and the other end of the first threaded rod 29 passes through the sliding plate 26 and is threadedly connected to the sliding plate 26. By rotating the first threaded rod 29, the first threaded rod 29 can drive the sliding plate 26 to move, thereby changing the tension of the first tension spring 27 and the pressure of the blocking plate 28 and changing the extrusion effect. The jacking mechanism 15 includes two push plates 40 and a fixed shaft 42. The fixed shaft 42 is fixedly connected between the inner walls on both sides of the limiting frame 11. A slantingly arranged ejector rod 43 is rotatably connected to the circumferential outer wall of the fixed shaft 42. A roller is rotatably connected to the top of the ejector rod 43, and the roller contacts the bottom of the filter plate 12. The two push plates 40 are respectively fixedly connected to the bottoms of the two driving frames 20, and a push shaft 41 is fixedly connected between the bottoms of the two push plates 40. While the driving frame 20 moves, it also drives the push plates 40 and the push shaft 41 to rotate. When the push shaft 41 contacts the ejector rod 43, it pushes the bottom of the ejector rod 43, and the top of the ejector rod 43 jacks up the filter plate 12. After the extrusion is completed, the filter plate 12 resets under its own gravity, preventing the raw materials from always adhering to the surface of the filter plate 12 and improving the filtering effect. The vibration mechanism 10 includes a fixed block 30 and a plurality of wedge-shaped blocks 37. The fixed block 30 is fixedly connected to the outer wall on one side of the feeding hopper 5. A penetrating mounting shaft 31 is rotatably connected to one side of the fixed block 30. At least one knocking block 32 is fixedly connected to the circumferential outer wall of the mounting shaft 31. At least one mounting rod 33 is fixedly connected to the circumferential outer wall of the mounting shaft 31. A second tension spring 34 is fixedly connected to one side of the mounting rod 33, and the other end of the second tension spring 34 is fixed to the feeding hopper 5. Two overrunning clutches 35 are symmetrically fixedly connected to the circumferential outer wall of the mounting shaft 31. A lever 36 is fixedly connected to the circumferential outer wall of each overrunning clutch 35. The plurality of wedge-shaped blocks 37 are evenly and symmetrically fixedly connected to the upper surfaces of the two driving frames 20 respectively. While the driving frame 20 moves, it also drives the wedge-shaped blocks 37 to move. After the wedge-shaped block 37 contacts the lever 36, it pushes the lever 36 to rotate. The lever 36 drives the mounting shaft 31 to rotate through the overrunning clutch 35. When the wedge-shaped block 37 disengages from the lever 36, the mounting shaft 31 resets under the pulling of the second tension spring 34.The feeding hopper 5 is struck by the striking block 32 to prevent the accumulation of raw materials. The adjusting mechanism includes a plug board 38 which is inserted into one side of the feeding hopper 5. A through second threaded rod 39 is threadedly connected to one side of the plug board 38. The other end of the second threaded rod 39 is rotatably connected to the feeding hopper 5. By rotating the second threaded rod 39, the second threaded rod 39 drives the plug board 38 to move, thereby changing the feeding speed.

[0044] The advantages of Embodiment 2 compared to Embodiment 1 are as follows:

[0045] 1. By providing the vibration mechanism 10 at the bottom of the feeding hopper 5, the driving frame 20 can strike the feeding hopper 5 through the striking block 32 while moving, preventing the accumulation and blockage of raw materials in the feeding hopper 5 and improving the feeding effect of the feeding hopper 5;

[0046] 2. By providing the jacking mechanism 15 installed in the limiting frame 11, the driving frame 20 can jack up the filter plate 12 while moving. Subsequently, after the extrusion is completed, the filter plate 12 falls under its own weight, preventing raw materials from adhering to the filter plate 12 and improving the filtering effect of the filter plate 12;

[0047] 3. By providing that the sliding plate 26 can be adjusted, after rotating the first threaded rod 29, the position of the sliding plate 26 can be changed, the tension of the first tension spring 27 and the pressure of the blocking plate 28 can be changed, thereby changing the extrusion effect and improving the flexibility of the device in use.

[0048] Working principle: During use, raw materials are put into the extrusion box 2 through the feeding hopper 5. When it is necessary to adjust the feeding speed of the feeding hopper 5, rotate the second threaded rod 39. The rotation of the second threaded rod 39 drives the movement of the plug board 38, thereby changing the feeding speed. Subsequently, start the hydraulic cylinder 7. The hydraulic cylinder 7 drives the movement of the pressing plate 8 to extrude the raw materials. The liquid in the raw materials is extruded through the filter plate 12 and then falls on the water collecting hopper 14 for convenient collection by people. After extrusion is completed, when continuing to extrude the raw materials, the raw materials push the blocking plate 28 downward to open the blocking plate 28. At the same time as the pressing plate 8 moves, it also drives the movement of the driving frame 20. The driving frame 20 pushes the guide rail 22 to move through the push rod 21, thereby driving the insertion frame 24 to push out the extruded raw materials to prevent the raw materials from staying on the blocking plate 28. At the same time as the driving frame 20 moves, it also drives the movement of the wedge block 37. After the wedge block 37 contacts the lever 36, it pushes the lever 36 to rotate. The lever 36 drives the installation shaft 31 to rotate through the overrunning clutch 35, thereby moving the knocking block 32 away from the feeding hopper 5. When the wedge block 37 disengages from the lever 36, the installation shaft 31 is reset under the pulling of the second tension spring 34, and then the feeding hopper 5 is knocked by the knocking block 32 to prevent the accumulation of raw materials. When the driving frame 20 returns, the one-way rotation characteristic of the overrunning clutch 35 is utilized to prevent the wedge block 37 from being stuck with the lever 36. At the same time as the driving frame 20 moves, it also drives the push plate 40 and the push shaft 41 to rotate. When the push shaft 41 contacts the ejector rod 43, it pushes the bottom of the ejector rod 43, and the top of the ejector rod 43 jacks up the filter plate 12. After extrusion is completed, the filter plate 12 is reset under its own gravity to prevent the raw materials from adhering to the surface of the filter plate 12 all the time and improve the filtering effect.

[0049] However, as is well known to those skilled in the art, the working principle and wiring method of the hydraulic cylinder 7 are common knowledge, and they both belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
