Description

Technical Field

[0001] The invention relates to a centrifuge, in particular to a combined pharmaceutical intermediate production device, belonging to the technical field of quick-brewed ganoderma lucidum substitute tea production. Background Art

[0002] In the prior art, for example, the invention with application number 202311187807.6 discloses a centrifuge for the production of arbidol hydrochloride. In order to solve the problem that the impurities filtered out by the existing centrifuge are easily attached to the inner wall of the filter cartridge during the centrifugal filtration, resulting in a decrease in the filtration performance of the filter cartridge, which seriously affects the normal centrifugal filtration. At the same time, it is necessary to manually clean the impurities on the filter cartridge, and the process is quite cumbersome, resulting in the problem of inconvenience in use. By setting a shovel ring, the shovel ring can be driven to move upward through the servo push cylinder. At this time, the slide groove on the tooth plate slides on the limiting block to guide the shovel ring so that the shovel ring can slide on the inner wall of the filter cartridge to scrape off the impurities adsorbed on the inner wall of the filter cartridge during centrifugal filtration, thereby ensuring the good filtration performance of the filter cartridge and allowing the centrifugal filtration to proceed normally. Although the scraping method can continuously clean the inner wall of the filter cartridge, the filter residue is also prone to cause clogging of the mesh. The scraping method cannot clean the impurities inside the mesh, affecting the filtration rate of the solution.

[0003] In the prior art, for example, the invention with application number 202310053061.3 discloses a centrifuge and screening method for polymer material production. In order to solve the problem that the polymer material is easily attached to the outer surface of the drum, which may not only cause the filter holes on the drum to be blocked, but also cause waste, the polymer material attached to the drum is appropriately shaken off by intermittent impact of the rubber head to prevent the filter holes on the drum from being blocked, thereby avoiding the phenomenon of polymer material waste. In addition, the driving device and the vibration mechanism are interconnected, and the mechanical structure performance is relatively strong. Through the mutual cooperation with the cleaning mechanism, the inner wall of the outer cylinder and the outer wall of the drum can be flushed, thereby reducing the waste of polymer materials again. There is no need to manually open the top cover for cleaning, which not only reduces the labor intensity, but also increases the convenience during use. Although the filter holes can be flushed and cleaned by flushing, they can only be cleaned after the centrifugal filtration is completed. The filter holes cannot be cleaned at the same time during the centrifugation process, which also affects the centrifugal rate.

[0004] Therefore, a combined pharmaceutical intermediate production device is designed to optimize the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide a combined pharmaceutical intermediate production device, wherein a centrifugal disk is rotatably installed inside a filter cartridge, and arc-shaped scrapers are evenly arranged between the outer side of the centrifugal disk and the filter cartridge, so that the inner wall of the filter cartridge can be scraped and cleaned while centrifugally filtering, and the lifting mechanism is used to control the lifting and lowering of the centrifugal disk, so that the position of the centrifugal disk inside the filter cartridge can be changed during the centrifugal process, and the local filter hole blockage and the influence of the centrifugal rate can be effectively avoided. In addition, two groups of annular nozzles are arranged on the outer side of the filter cartridge, and the annular nozzles are located at the side and bottom of the centrifugal disk, and then used in conjunction with the infusion component, and the two groups of annular nozzles are lifted and lowered together with the centrifugal disk, so that during the lifting and lowering process of the centrifugal disk, not only the inner wall of the filter cartridge can be scraped and cleaned, but also the filter holes can be rinsed and cleaned from the outside by the annular nozzles, thereby ensuring the permeability of the filter holes and improving the centrifugal filtration rate. By fixing the liquid inlet pipe at the middle position of the centrifugal disk, and providing a collecting bucket on the top of the centrifugal disk, after the inner wall of the filter cartridge is scraped and cleaned, the filter residue can fall into the inside of the collecting bucket along the arc-shaped scraper, When used in conjunction with an outer sleeve, a material guide pipe and a spiral blade, the scraped raw materials can be automatically discharged outward during centrifugal filtration, which is more practical. The lifting mechanism is composed of a reducer, a pulley mechanism, a transmission shaft, a reciprocating screw, a slider and a fixed rod. The pulley mechanism connects the driving shaft of the reducer with the output shaft of the driving motor, and the fixed rod is located outside the outer sleeve. During the rotation of the driving motor, the slider outside the reciprocating screw can be controlled by transmission to drive the fixed rod to slowly rise and fall, thereby controlling the up and down movement of the centrifugal disk, which is more convenient to control. In addition, the material guide pipe is fixedly connected to the annular nozzle through a vertical rod, and the movement of the annular nozzle can be controlled at the same time. Through the infusion assembly composed of the first cylinder body, the first piston, the liquid extraction pipe, the liquid discharge pipe, the crankshaft and the first connecting rod, the liquid after centrifugation can be automatically extracted and injected into the inside of the annular nozzle during the centrifugal process. In addition, when used in conjunction with the second cylinder body, the second piston, the circulation pipe, the reflux pipe and the second connecting rod, the flushing waste liquid at the bottom of the casing can be automatically circulated for circulating centrifugal filtration.

DETAILED DESCRIPTION

[0031] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0032] like Figure 1-Figure 8 As shown, this embodiment provides a combined pharmaceutical intermediate production device, including a casing 1, a base 2 located below the casing 1, and a filter cartridge 3 vertically fixed inside the casing 1, a centrifugal disc 4 is rotatably installed inside the filter cartridge 3, a cavity 5 is opened inside the centrifugal disc 4, the bottom end of the cavity 5 is in a conical protrusion shape, and centrifugal blades 6 are evenly arranged on the outer side of the conical protrusion at the bottom end of the cavity 5, and a discharge port 7 is evenly opened on the outer side of the centrifugal disc 4, and an arc scraper 8 is evenly fixed on the outer side of the centrifugal disc 4, and the arc scraper 8 is inclined. The centrifugal disc 4 is arranged on the top thereof and fits with the inner side of the filter cartridge 3. A collecting bucket 9 is provided on the top of the centrifugal disc 4. A liquid inlet pipe 11 is vertically fixed at the middle position of the bottom of the collecting bucket 9. A partition 10 fitting with the inner side of the filter cartridge 3 is rotatably installed on the bottom of the centrifugal disc 4. A flushing mechanism for cleaning the filter holes inside the filter cartridge 3 is provided on the outside of the filter cartridge 3. A driving mechanism for controlling the rotation of the centrifugal disc 4 is provided on the bottom of the centrifugal disc 4. A filter residue discharging mechanism is provided on the top of the centrifugal disc 4. A lifting mechanism for controlling the centrifugal disc 4 to move up and down inside the filter cartridge 3 is provided on the outside of the casing 1.

[0033] The general working principle is as follows: when in use, the solution after decoction and extraction is injected into the inside of the centrifugal disc 4 from the liquid inlet pipe 11, and the driving mechanism drives the centrifugal disc 4 to rotate at a high speed. The centrifugal blades 6 inside the centrifugal disc 4 exert centrifugal force on the solution to throw the liquid out from the discharge port 7. The impurities in the liquid will stick to the inner side of the filter cartridge 3, and the liquid will pass through the filter cartridge 3 and fall to the outside of the bottom of the casing 1 for discharge. While centrifuging, the arc scraper 8 rotates with the centrifugal disc 4, and the arc scraper 8 scrapes off the impurities on the inner wall of the filter cartridge 3. Due to the obstruction of the partition 10, the filter residue will not fall to the bottom of the casing 1. On the other hand, since the arc scraper 8 is inclined to provide an upward thrust for the filter residue, the filter residue moves upward along the arc scraper 8, then falls into the collecting bucket 9, and is discharged to the outside of the casing 1 through the filter residue discharge mechanism. In addition, during the centrifugal process, the use height of the centrifugal disk 4 can be controlled by the lifting mechanism to ensure that the centrifugal filtration operation is performed on different planes inside the filter cartridge 3, thereby ensuring the effect of the centrifugal filtration. In addition, during the lifting and lowering process of the centrifugal disk 4, the flushing mechanism is also started at the same time to backwash the filter holes of the filter cartridge 3 from the outside of the filter cartridge 3 to ensure the permeability of the filter cartridge 3.

[0034] In this embodiment, the driving mechanism includes a sleeve 16, a spline shaft 17 and a driving motor 18. The sleeve 16 is fixed at the middle position of the bottom end of the centrifugal disk 4. The spline shaft 17 is vertically slidably installed inside the sleeve 16. The spline shaft 17 is rotatably connected to the bottom of the casing 1 and extends to the bottom of the casing 1. The top of the base 2 is installed with a driving motor 18 that drives the spline shaft 17 to rotate.

[0035] Local working principle: During use, the driving motor 18 can drive the spline shaft 17 to rotate, the spline shaft 17 drives the sleeve 16 to rotate, the sleeve 16 controls the rotation of the centrifugal disk 4, and in the process of the centrifugal disk 4 sliding up and down, the sleeve 16 is driven to move up and down. The spline shaft 17 is always located inside the sleeve 16 to ensure the stable rotation of the centrifugal disk 4.

[0036] In this embodiment, the shaft sleeve 16 passes through the partition 10 and is rotatably connected to the partition 10 , and a rubber sealing ring is provided between the outer side of the partition 10 and the inner side of the filter cartridge 3 .

[0037] Partial working principle: The use of the partition 10 effectively prevents the filter residue from falling to the bottom of the casing 1, and also prevents the solution thrown out from the inside of the centrifugal disc 4 from flowing into the bottom of the casing 1.

[0038] In this embodiment, the filter residue discharge mechanism includes an outer sleeve 12, a material guide pipe 13 and a spiral blade 14. The outer sleeve 12 is sleeved on the outside of the liquid inlet pipe 11, and the material guide pipe 13 is vertically installed on the top of the outer side of the outer sleeve 12. The liquid inlet pipe 11 passes through the top of the outer sleeve 12 and is rotatably connected to the outer sleeve 12. The outer side of the liquid inlet pipe 11 is fixed with a spiral blade 14, and the outer side of the spiral blade 14 is in contact with the inner side of the outer sleeve 12.

[0039] Local working principle: During the centrifugal filtration process, the liquid inlet pipe 11 rotates with the centrifugal disk 4, and the outer sleeve 12 is fixed relative to the liquid inlet pipe 11. The rotation of the liquid inlet pipe 11 will drive the spiral blade 14 to rotate. The rotation of the spiral blade 14 can transport the filter residue inside the collecting bucket 9 upward and then discharge it from the guide pipe 13.

[0040] In this embodiment, a lower hopper 15 is rotatably mounted on the top of the liquid inlet pipe 11, and the interior of the lower hopper 15 is funnel-shaped.

[0041] Partial working principle: The setting of the lower hopper 15 can ensure stable installation with the decoction and extraction liquid pipeline, and is more convenient to use.

[0042] In this embodiment, the lifting mechanism includes a reducer 19, a pulley mechanism 20, a transmission shaft 21, a reciprocating screw 22, a slider 23 and a fixed rod 24. The reducer 19 is installed on the top of the base 2. A pulley mechanism 20 is provided between the driving shaft of the reducer 19 and the output end of the driving motor 18. The output shaft of the reducer 19 is installed with a transmission shaft 21. A reciprocating screw 22 is fixed to the top of the transmission shaft 21. A slider 23 is provided on the reciprocating screw 22. A fixed rod 24 is fixed between the outer side of the slider 23 and the outer side of the outer sleeve 12.

[0043] Local working principle: During centrifugal filtration, the driving motor 18 can drive the reducer 19 to rotate through the pulley mechanism 20, thereby controlling the transmission shaft 21 to operate at a low speed. The transmission shaft 21 drives the reciprocating screw 22 to rotate, and the slider 23 reciprocates on the reciprocating screw 22, thereby driving the outer sleeve 12 and the centrifugal disc 4 to move up and down through the fixed rod 24.

[0044] In this embodiment, positioning blocks are evenly fixed on the outer side of the housing 1 on the same vertical line, and the transmission shaft 21 passes through the inside of the positioning blocks and is rotatably connected to the positioning blocks.

[0045] Partial working principle: By using the positioning block, the stable rotation of the transmission shaft 21 can be ensured.

[0046] In this embodiment, the flushing mechanism includes an annular nozzle 25, a nozzle 26, a vertical rod 38 and an infusion assembly. The annular nozzle 25 is sleeved on the outside of the filter cartridge 3, and there are two groups of annular nozzles 25. The two groups of annular nozzles 25 are parallel to each other and fixed by a connecting rod. The annular nozzle 25 at the bottom of the outer side of the filter cartridge 3 is located below the partition 10, and the annular nozzle 25 at the top of the outer side of the filter cartridge 3 is located above the discharge port 7 and below the horizontal plane of the top of the centrifugal disk 4. A vertical rod 38 is fixed between the annular nozzle 25 at the top of the outer side of the filter cartridge 3 and the guide pipe 13. An infusion assembly is provided on the outside of the annular nozzle 25, and a flushing liquid circulation assembly is provided at the bottom end of the casing 1.

[0047] Local working principle: while the outer sleeve 12 and the guide tube 13 are rising and falling, the two groups of annular nozzles 25 will be driven to move through the vertical rod 38, and the infusion component will inject the centrifugally filtered liquid into the annular nozzle 25. During the upward movement of the centrifugal disk 4, the bottom annular nozzle 25 discharges the liquid from the nozzle 26 to flush the filter holes blocked after scraping and cleaning, and the flushing liquid falls into the bottom of the casing 1. The slag-containing liquid is extracted into the lower hopper 15 by the flushing liquid circulation component and then put into the bottom. The top annular nozzle 25 also sprays a certain amount of liquid, which can pre-clear the area that the centrifugal disk 4 is about to reach, and the flushing liquid is thrown out again by the centrifugal force exerted by the arc scraper 8 to pass through the filter cartridge 3 and fall to the outside of the bottom of the casing 1 for storage. If the centrifugal disk 4 descends, the filter holes are backwashed and cleared by the liquid discharged from the top annular nozzle 25, and the filter holes are pre-cleared by the liquid discharged from the bottom annular nozzle 25.

[0048] In this embodiment, the infusion assembly includes a first cylinder body 27, a first piston 28, a suction tube 29, a discharge tube 30, a crankshaft 35 and a first connecting rod 36. The first cylinder body 27 is installed below the casing 1. The first piston 28 is slidably installed inside the first cylinder body 27. The end of the first cylinder body 27 is provided with a suction tube 29 that is connected to the bottom of the casing 1. The end of the first cylinder body 27 is provided with a discharge tube 30 that is connected to the inside of the annular nozzle 25. A crankshaft 35 is installed between the output end of the drive motor 18 and the spline shaft 17. The first connecting rod 36 is hingedly installed on the side of the first piston 28, and the end of the first connecting rod 36 is rotatably connected to the center of the crankshaft 35.

[0049] Local working principle: During the rotation of the drive motor 18, the crankshaft 35 is controlled to rotate. When the crankshaft 35 rotates, it cooperates with the first connecting rod 36 to control the first piston 28 to slide inside the first cylinder 27. When the first piston 28 slides outward, the filtered liquid is drawn into the first cylinder 27 through the suction pipe 29. When the first piston 28 slides toward the inside of the first cylinder 27, the liquid inside the first cylinder 27 is discharged from the discharge pipe 30 to the inside of the annular nozzle 25.

[0050] In this embodiment, the flushing liquid circulation assembly includes a second cylinder body 31, a second piston 32, a circulation pipe 33, a return pipe 34 and a second connecting rod 37. The second cylinder body 31 is installed on the side of the bottom of the casing 1 away from the first cylinder body 27. The second piston 32 is slidably installed inside the second cylinder body 31, and the second connecting rod 37 is hingedly installed on the side of the second piston 32. The end of the second connecting rod 37 is rotatably connected to the middle position of the crankshaft 35. A circulation pipe 33 is provided between the end of the second cylinder body 31 and the inner bottom of the casing 1, and a return pipe 34 is installed between the end of the second cylinder body 31 and the side of the lower hopper 15.

[0051] Local working principle: During the rotation of the crankshaft 35 , the second piston 32 is controlled to slide inside the second cylinder 31 by the second connecting rod 37 , and the liquid at the bottom of the casing 1 is extracted by the circulation pipe 33 and injected into the lower hopper 15 through the reflux pipe 34 .
