Description

Technical Field

[0001] This utility model relates to the field of extraction and separation machine technology, specifically a centrifugal extraction and separation machine for biomedicine. Background Technology

[0002] Biomedical extraction is a process involving the extraction, separation, and purification of bioactive compounds from natural products. These natural products can come from various sources such as plants, animals, and microorganisms, while the target compounds typically include pharmaceutical, health product ingredients, and other high-value bioactive molecules. Centrifugal extraction is a novel extraction technology that uses a centrifugal extractor as its core equipment. It is characterized by high efficiency, continuous operation, and environmental friendliness, and it is widely used in many fields of biomedicine.

[0003] Regarding centrifugal extraction separators for biopharmaceutical applications, a search revealed a publication (application number) CN217645981U. This centrifugal extraction separator, through the cooperation of a second motor, rotating tube, rotating rod, and cleaning brush, can automatically clean the filter cartridge, avoiding the tedious process of disassembling and cleaning the cartridge. The height of the cleaning brush can be adjusted through the cooperation of the rotating rod, third motor, screw, and drive block, allowing the brush to switch between cleaning and stop modes and increasing its cleaning range for more comprehensive cleaning of the filter cartridge. However, the cleaning brush is designed inside the filter cartridge and cannot be removed after cleaning. The rotating rod and cleaning brush being inside the filter cartridge also affect normal centrifugal extraction and separation operations, and the internal location of the cleaning brush makes replacement inconvenient.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figures 1-7 As shown, a centrifugal extraction and separation machine for biomedicine includes: a separator body 1, a filter cylinder 101 installed inside the separator body 1, multiple filter holes 102 opened on the outside of the filter cylinder 101, a cylinder cover 103 threadedly connected to the top of the filter cylinder 101, a feed hopper 104 installed on the top of the cylinder cover 103, a cleaning assembly set on the top of the filter cylinder 101, the cleaning assembly including: a workbench 2, a support frame 201, a lifting cylinder 202, a telescopic rod 203, an installation cylinder 204 and a cleaning block 205, and a filter assembly set at the bottom of the separator body 1, the filter assembly including: a drain pipe 5, a secondary filter box 501, a pad block 502, a filter plate 503, a fine filter screen 504, a handle 505 and a collection box 506.

[0028] The workbench 2 is equipped with a mounting base 3. The mounting base 3 has through holes 301 on both sides of its outer end. Each through hole 301 is equipped with a fixing screw 302. The separator body 1 has screw holes on both sides of its outer end. A handle 303 is installed on the outside of the fixing screw 302.

[0029] When using the separator body 1, place the separator body 1 inside the mounting base 3, so that the screw holes on both sides of the outer end of the separator body 1 are directly opposite the through holes 301 on both sides of the outer end of the mounting base 3. At this time, insert the fixing screw 302 from the through hole 301 into the screw hole, and grasp the handle 303 to rotate the fixing screw 302, so that the fixing screw 302 is tightened inside the screw hole, thereby fixing the separator body 1 and the mounting base 3 together, that is, the separator body 1, the mounting base 3 and the worktable 2 are used as a whole.

[0030] The separator body 1 has a limit frame 105 installed on the top, and a bearing 106 that is rotatably connected to the filter cartridge 101 is installed inside the limit frame 105. A servo motor 107 is installed at the bottom of the separator body 1, and a motor shaft 108 is connected to the top output end of the servo motor 107. The motor shaft 108 passes through the separator body 1 and is connected to the filter cartridge 101. The motor shaft 108 and the separator body 1 are rotatably connected by a sealed bearing.

[0031] After the separator body 1 is installed securely, when extracting and removing impurities from the liquid medicine, the liquid medicine is poured from the feed hopper 104 into the filter cylinder 101. At this time, the servo motor 107 is started. The servo motor 107 drives the motor shaft 108 to rotate the filter cylinder 101 and generate centrifugal force. Under the action of centrifugal force, the liquid medicine inside the filter cylinder 101 is thrown out from multiple filter holes 102 and falls into the separator body 1. Through the action of centrifugal force, impurities in the liquid medicine can be quickly extracted and removed.

[0032] During the rotation of the filter cartridge 101, the top of the filter cartridge 101 is limited by the limiting frame 105, and the normal rotation of the filter cartridge 101 is ensured by the bearing 106.

[0033] The separator body 1 has drain pipes 5 installed on both sides of the bottom. A secondary filter box 501 is installed at the bottom of the drain pipes 5. Pads 502 are installed on both sides inside the secondary filter box 501. A filter plate 503 is installed on the top of the pads 502. A fine filter screen 504 is installed inside the filter plate 503. Handles 505 are installed on both sides of the top of the filter plate 503. A collection box 506 is installed at the bottom of the filter plate 503.

[0034] After the extracted and purified medicinal liquid falls into the separator body 1, it can be discharged from the outside of the separator body 1 through the drain pipe 5. That is, the medicinal liquid is discharged from the drain pipe 5 into the secondary filter box 501, so that the medicinal liquid falls on the filter plate 503. The medicinal liquid can be filtered a second time through the fine filter screen 504 inside the filter plate 503, which makes it easier to filter out the fine impurities in the medicinal liquid, improve the purity of the extracted medicinal liquid, and avoid the impurities remaining and affecting the quality of the pharmaceutical.

[0035] During use, the filter plate 503 is supported by the pad 502 to ensure that it is placed flat. When there are many impurities filtered on the fine filter screen 504, the filter plate 503 can be lifted out of the secondary filter box 501 by grasping the handle 505 to apply force. This makes it easier to clean the impurities on the fine filter screen 504 and rinse it clean to prevent the mesh of the fine filter screen 504 from becoming clogged and affecting normal filtration.

[0036] The filter cartridge 101 has a connecting cylinder 4 installed at its bottom. Inside the connecting cylinder 4 are three reinforcing rubber rings 401 that are adapted to the motor shaft 108. The motor shaft 108 is movably connected to the reinforcing rubber rings 401. After the filter cartridge 101 is used, many impurities are filtered inside. The filter cartridge 101 can be grabbed and pulled upwards. When the filter cartridge 101 is under force, the motor shaft 108 disengages from the reinforcing rubber rings 401 inside the connecting cylinder 4, so that the connecting cylinder 4 is separated from the motor shaft 108. The filter cartridge 101 can be lifted and pulled out from the limiting frame 105 and the bearing 106. Then, the cylinder cover 103 is rotated to loosen and disassembled from the top of the filter cartridge 101, making it easy to pour out and clean the impurities inside the filter cartridge 101.

[0037] After cleaning the impurities from the filter cartridge 101, insert the filter cartridge 101 into the separator body 1 from the limiting frame 105. That is, the connecting cylinder 4 at the bottom of the filter cartridge 101 can be inserted into the motor shaft 108. At this time, the connecting cylinder 4 can be sleeved together with the motor shaft 108 through the reinforcing rubber ring 401. The reinforcing rubber ring 401 can increase the stability of the connection between the connecting cylinder 4 and the motor shaft 108.

[0038] Among them, the bottom of the separator body 1 is equipped with a workbench 2, the top side of the workbench 2 is equipped with a support frame 201, the top of the support frame 201 is equipped with a lifting cylinder 202, the bottom output end of the lifting cylinder 202 is connected to a telescopic rod 203, the bottom of the telescopic rod 203 is equipped with an installation cylinder 204, and the bottom of the installation cylinder 204 is equipped with a cleaning block 205.

[0039] When the filter cartridge 101 needs to be cleaned after use, loosen and remove the top cover 103 of the filter cartridge 101. At this time, start the lifting cylinder 202 to drive the telescopic rod 203 to move downward, so that the telescopic rod 203 pushes the mounting cylinder 204 and the cleaning block 205 downward into the filter cartridge 101. This can drive the cleaning block 205 to move up and down inside the filter cartridge 101 and pour clean water into the filter cartridge 101. The cleaning block 205 can clean the inside of the filter cartridge 101. After cleaning, the cleaning block 205 and the telescopic rod 203 can be removed from the outside of the filter cartridge 101 without affecting the normal centrifugal extraction and separation of the medicine in the filter cartridge 101, and it is also convenient to replace the cleaning block 205.

[0040] The size of the cleaning block 205 is the same as the inner diameter of the filter cylinder 101, meaning that the cleaning block 205 can fit against the inner wall of the filter cylinder 101, ensuring that the filter cylinder 101 can be cleaned thoroughly.

[0041] The telescopic rod 203 has an external thread layer 206 on its bottom outer side, and the mounting cylinder 204 has an internal thread layer that is threaded to the external thread layer 206. When the cleaning block 205 is in use, it is installed and used together with the telescopic rod 203 through the mounting cylinder 204. That is, the internal thread layer on the inner wall of the mounting cylinder 204 is threaded to the external thread layer 206 on the bottom outer side of the telescopic rod 203, so that the mounting cylinder 204 and the telescopic rod 203 can be flexibly installed. When the cleaning block 205 is worn, it is easy to disassemble and replace it with a new one.

[0042] Working principle:

[0043] When using the separator body 1, place the separator body 1 inside the mounting base 3, so that the screw holes on both sides of the outer end of the separator body 1 are directly opposite the through holes 301 on both sides of the outer end of the mounting base 3. At this time, insert the fixing screw 302 from the through hole 301 into the screw hole, and grasp the handle 303 to rotate the fixing screw 302, so that the fixing screw 302 is tightened inside the screw hole, thereby fixing the separator body 1 and the mounting base 3 together. That is, the separator body 1, the mounting base 3 and the worktable 2 are used as a whole. After the separator body 1 is installed securely, when extracting and removing impurities from the liquid medicine, pour the liquid medicine from the feed hopper 104 into the filter cylinder 101. At this time, start the servo motor 107 to work. The servo motor 107 drives the motor shaft 108 to drive the filter cylinder 101 to rotate and generate centrifugal force. Under the action of centrifugal force, the liquid medicine inside the filter cylinder 101 is thrown out from multiple filter holes 102 and falls into the separator body 1. Through the action of centrifugal force, the impurities in the liquid medicine can be quickly extracted and removed.

[0044] After the extracted and purified medicinal liquid falls into the separator body 1, it can be discharged from the outside of the separator body 1 through the drain pipe 5. That is, the medicinal liquid is discharged from the drain pipe 5 into the secondary filter box 501, so that the medicinal liquid falls on the filter plate 503. The medicinal liquid can be filtered a second time through the fine filter screen 504 inside the filter plate 503, which makes it easier to filter out the fine impurities in the medicinal liquid, improve the purity of the extracted medicinal liquid, and avoid the impurities remaining and affecting the quality of the pharmaceutical.

[0045] When the filter cartridge 101 needs to be cleaned after use, loosen and remove the top cover 103 of the filter cartridge 101. At this time, start the lifting cylinder 202 to drive the telescopic rod 203 to move downward, so that the telescopic rod 203 pushes the mounting cylinder 204 and the cleaning block 205 downward into the filter cartridge 101. This can drive the cleaning block 205 to move up and down inside the filter cartridge 101 and pour clean water into the filter cartridge 101. The cleaning block 205 can clean the inside of the filter cartridge 101. After cleaning, the cleaning block 205 and the telescopic rod 203 can be removed from the outside of the filter cartridge 101 without affecting the normal centrifugal extraction and separation of the medicine in the filter cartridge 101, and it is also convenient to replace the cleaning block 205.
