DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 10 As shown, the present invention provides a biomedical drug extraction and filtration device, comprising a sealing cylinder 1;

[0035] A feed pipe 2 is arranged on one side of the surface of the sealing cylinder 1;

[0036] The filter cartridge 3 is placed inside the sealing cartridge 1;

[0037] The blowing mechanism 4 is arranged on the outer surface of the sealing cylinder 1, and includes a fixed shell 401, which is fixedly connected to the outer surface of the sealing cylinder 1, and the fixed shell 401 is rotatably connected to the inside of the fixed shell 401. A water pipe 403 is fixedly installed on the top of the fixed shell 401, and the other end of the water pipe 403 extends to the inside of the feed pipe 2, and a fan blade 404 is fixedly installed on one side of the impeller 402. An exhaust groove 405 is opened inside the sealing cylinder 1, and an exhaust hole 406 is opened in the inner cavity of the exhaust groove 405.

[0038] The above scheme is adopted: the operator connects the pipe containing the medicine solution to the feed pipe 2, and then the medicine solution passes through the feed pipe 2 into the interior of the sealing cylinder 1 and falls into the interior of the filter cylinder 3, and then the filter cylinder 3 can filter out impurities in the medicine solution, thereby ensuring the purity and quality of the drug extract;

[0039] Since the other end of the connecting water pipe 403 extends to the inside of the feed pipe 2, when the medicine enters the inside of the feed pipe 2, a part of the medicine will enter the inside of the connecting water pipe 403, and then pass through the connecting water pipe 403 to enter the inside of the fixed shell 401, and then the flowing medicine will contact the fan blades on the surface of the impeller 402, and will drive the impeller 402 to rotate, and the impeller 402 will drive the fan blades 404 to rotate. During the rotation of the fan blades 404, the blowing gas is generated to enter the inside of the exhaust groove 405, and then it will be discharged from the exhaust hole 406, and then the flowing gas will disperse the The residual medicine at the top of the filter cylinder 3 is blown into the interior of the filter cylinder 3, and finally the flowing medicine drives the fan blade 404 to rotate, and the moving gas is used to blow the medicine scattered at the top of the filter cylinder 3 into the interior of the filter cylinder 3, so as to avoid the medicine remaining at the top of the filter cylinder 3, thereby reducing the accumulation of medicine at the top of the filter cylinder, avoiding the risk of drug loss and contamination due to residue, and ensuring the filtration efficiency, because the flowing gas ensures the continuous cleaning of the top of the filter cylinder 3, so that the medicine can be filtered by the filter cylinder 3 without hindrance, thereby improving the purity and yield of drug extraction.

[0040] like Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, it also includes: a blocking mechanism 5, which is arranged inside the sealing tube 1, and the blocking mechanism 5 includes a fixed groove 501, which is opened inside the sealing tube 1, and the inner cavity of the fixed groove 501 is opened with a square groove 502, one end of the square groove 502 is connected with the fixed groove 501, and the other end of the square groove 502 is connected with the exhaust groove 405, the inner cavity of the square groove 502 is fixedly installed with an electromagnetic valve 503, the interior of the fixed groove 501 is provided with a spring 504, one end of the spring 504 is fixedly installed with a movable plate 505, and a blocking plate 506 is hinged on one side of the movable plate 505.

[0041] The above scheme is adopted: through the design of the blocking mechanism 5, when the gas enters the exhaust groove 405, the electromagnetic valve 503 can be opened, and then the gas will pass through the electromagnetic valve 503 and enter the interior of the square groove 502. Since one side of the square groove 502 is connected with the fixed groove 501, the gas will pass through the square groove 502 and enter the interior of the fixed groove 501. Then the air pressure in the fixed groove 501 will increase, and then the gas will squeeze the movable plate 505. During the squeezing process, the movable plate 505 will move. When the movable plate 505 moves, When the air is exhausted, the spring 504 will be stretched, and then the movable plate 505 will push the blocking plate 506 to move out of the fixed groove 501, and then the blocking plate 506 will move to the side of the exhaust hole 406, thereby blocking the liquid medicine and preventing the liquid medicine from entering the exhaust groove 405 along the exhaust hole 406, and finally entering the fixed groove 501 through the flowing gas, and pushing the blocking plate 506 to move to block the liquid medicine and prevent the liquid medicine from entering the exhaust groove 405, thereby ensuring that the blowing mechanism 4 can work continuously and stably, and significantly reducing the waste of costs.

[0042] like Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, it also includes: a blocking mechanism 6, which is arranged inside the sealing cylinder 1, and the blocking mechanism 6 includes a fixed groove 2 601, and the fixed groove 2 601 is opened inside the sealing cylinder 1, and the inner cavity of the fixed groove 2 601 is fixedly installed with a spring 2 602, and one end of the spring 2 602 is fixedly installed with a sealing plate 603, and one side of the sealing plate 603 is fixedly installed with a rack 604, and the sealing cylinder 1 is provided with a fixed groove 3 605, and the top of the fixed groove 3 605 is connected with the square groove 1 502, and the inner cavity of the fixed groove 3 605 is rotatably connected with a gear 606 meshing with the rack 604, and the top of the gear 606 is fixedly installed with a screw rod 607, and the surface of the screw rod 607 is threadedly sleeved with a blocking block 608, and the inner cavity of the exhaust groove 405 is provided with a square groove 2 609, and one end of the square groove 2 609 is connected with the fixed groove 2 601, and the square groove 2 609 is provided with an electromagnetic valve 2 610.

[0043] The above scheme is adopted: through the design of the blocking mechanism 6, when the electromagnetic valve 1 503 is opened, the electromagnetic valve 2 610 can also be opened, and then the gas inside the exhaust groove 405 will also enter the inside of the square groove 2 609. Since one end of the square groove 2 609 is connected with the fixed groove 2 601, the gas will enter the inside of the fixed groove 2 601. Since the surface of the sealing plate 603 is fully in contact with the fixed groove 2 601, the flowing gas will push the sealing plate 603 to move. When the sealing plate 603 moves, the spring 2 602 will be stretched, and then the sealing plate 603 will push the rack 604 to move inside the fixed groove 2 601. Because the rack 604 is engaged with the gear 606, the rack 604 will drive the gear 606 to rotate. When the screw rod 607 rotates, the gear 606 will drive the screw rod 607 to rotate. Since the screw rod 607 is threadedly connected with the blocking block 608, the blocking block 608 will move on the surface of the screw rod 607, and then the blocking block 608 will pass through the fixed groove three 605 and enter the interior of the square groove 502, so as to block the square groove 502 and prevent the gas from entering the interior of the fixed groove 501 all the time, resulting in excessive pressure inside the fixed groove 501. Finally, the rack 604 is pushed by the gas to make the blocking block 608 block the square groove 502 and prevent the fixed groove 501 from being over-pressured and causing damage to the internal components of the fixed groove 501, thereby improving the safety and reliability of the entire filtering device and providing a strong guarantee for the smooth progress of the drug extraction process.

[0044] like Figure 4 and Figure 8 As shown, a guide ring 8 located on one side of the fan blade 404 is fixedly installed inside the fixed shell 401, and the guide ring 8 is of conical design.

[0045] The above scheme is adopted: through the design of the guide ring 8, since the guide ring 8 is a conical design, when the fan blade 404 blows the gas, the guide ring 8 will guide the gas to the inside of the exhaust groove 405, thereby ensuring the orderly flow of the gas and effectively improving the utilization efficiency of the gas.

[0046] like Figure 1 and Figure 2 As shown, it also includes: a cleaning component 9, which is arranged at the top of the sealing cylinder 1, and the cleaning component 9 includes a motor 901, and the motor 901 is fixedly installed at the top of the sealing cylinder 1. The output end of the motor 901 extends to the interior of the sealing cylinder 1 and is installed with a rotating rod 902 located inside the filter cylinder 3, and the surface of the rotating rod 902 is fixedly installed with a cleaning blade 903 located inside the filter cylinder 3, and the surface of the cleaning blade 903 is in contact with the inner wall of the filter cylinder 3.

[0047] The above scheme is adopted: through the design of the cleaning component 9, the motor 901 can be driven to rotate the rotating rod 902, and the rotating rod 902 will drive the cleaning blade 903 to rotate. Because the surface of the cleaning blade 903 is in contact with the inner wall of the filter cartridge 3, when the cleaning blade 903 rotates, the inside of the filter cartridge 3 can be cleaned to prevent impurities from remaining inside the filter cartridge 3 and clogging the filter holes on the surface of the filter cartridge 3, thereby ensuring the filtering effect of the filter cartridge 3.

[0048] like Figure 2 As shown, a sealing shell 10 is threadedly sleeved on the bottom end of the surface of the sealing cylinder 1 , and a support block 11 located inside the sealing cylinder 1 is fixedly installed in the inner cavity of the sealing shell 10 , and the top end of the support block 11 contacts the bottom end of the filter cylinder 3 .

[0049] The above scheme is adopted: through the design of the sealing shell 10 and the support block 11, since the sealing shell 10 is threadedly connected to the sealing cylinder 1, the sealing shell 10 can be rotated, so that the sealing shell 10 will be separated from the bottom end of the sealing cylinder 1, and then the filter cylinder 3 can be taken out from the inside of the sealing cylinder 1 to clean the impurities inside the filter cylinder 3. After the cleaning is completed, the filter cylinder 3 can be reinserted into the inside of the sealing cylinder 1, and then the sealing shell 10 is put on the bottom end of the sealing cylinder 1, and then the support block 11 will enter the inside of the sealing cylinder 1, and will contact with the bottom end of the filter cylinder 3, and then the support block 11 can support the filter cylinder 3.

[0050] like Figure 2 and Fig. 9 As shown, it also includes:

[0051] The reflux mechanism 7 is arranged on one side of the fixed shell 401. The reflux mechanism 7 includes an extraction component 701, which is fixedly connected to one side of the fixed shell 401. A reflux pipe 702 is fixedly installed at the output end of the extraction component 701, and one side of the reflux pipe 702 extends to the interior of the sealing tube 1.

[0052] The above scheme is adopted: through the design of the reflux mechanism 7, after the medicine drives the impeller 402 to rotate, the extraction component 701 can be driven to make the reflux pipe 702 extract the medicine inside the fixed shell 401, and then the medicine will flow back into the interior of the filter cylinder 3, and when the extraction component 701 extracts the medicine, the flow speed of the medicine can be increased, thereby ensuring that the impeller 402 can rotate stably.

[0053] like Figure 5 and Figure 6 As shown, the blocking plate 506 is inclined and located at the top of the exhaust hole 406 , and the side of the blocking plate 506 close to the exhaust hole 406 is arc-shaped.

[0054] The above scheme is adopted: through the design of the blocking plate 506, since the blocking plate 506 is inclined, the medicine can be introduced into the interior of the filter cartridge 3 while blocking the medicine, and the side of the blocking plate 506 close to the exhaust hole 406 is arc-shaped, which can guide the flowing gas to the top of the filter cartridge 3, thereby ensuring that the gas can clean the medicine remaining on the top of the filter cartridge 3.

[0055] like Figure 6 and Fig.10 As shown, the movable plate 505 is square in design, and the surface of the movable plate 505 fully fits the inner wall of the fixing groove 1 501 . The number of the springs 2 602 is two, and they are designed to be longitudinally symmetrical about the center of the sealing plate 603 .

[0056] The above scheme is adopted: through the design of the movable plate 505, since the surface of the movable plate 505 fits with the inner wall of the fixed groove 501, the sealing between the movable plate 505 and the fixed groove 501 can be ensured, so that the flowing gas can push the movable plate 505 to move through the design of the spring 2 602. Since the sealing plate 603 is symmetrically designed, the sealing plate 603 and the rack 604 can move stably when stretched.

[0057] The working principle and use process of the present invention:

[0058] First, the operator can connect the pipe containing the medicine to the feed pipe 2, and then the medicine will pass through the feed pipe 2 and flow into the interior of the filter cartridge 3, and then the filter cartridge 3 can filter the medicine; then the filtered medicine will flow out from the drain pipe on the other side of the surface of the sealing cartridge 1, and while the medicine enters the interior of the feed pipe 2, a part of the medicine will enter the interior of the connecting water pipe 1 403, and then the medicine will enter the interior of the fixed shell 401, and will drive the impeller 402 to rotate, and the impeller 402 will drive the fan blade 404 to rotate. During the rotation of the fan blade 404, the gas will be blown into the interior of the exhaust groove 405 and will be discharged from the exhaust hole 406, and then the gas will blow the medicine residue scattered on the top of the filter cartridge 3 into the interior of the filter cartridge 3 to prevent the medicine from accumulating on the top of the filter cartridge 3;

[0059] When the gas enters the exhaust groove 405, the electromagnetic valve 503 can be opened, and then the gas passes through the square groove 502 and enters the fixed groove 501, and then the gas pushes the movable plate 505 and the blocking plate 506 to move. When the movable plate 505 moves, the spring 504 is stretched, and the blocking plate 506 moves out of the fixed groove 501, and then the blocking plate 506 moves to one side of the exhaust hole 406, thereby blocking the liquid medicine and preventing the liquid medicine from entering the exhaust groove 405 along the exhaust hole 406;

[0060] At the same time, the solenoid valve 2 610 can be opened, and the gas inside the exhaust groove 405 will also pass through the solenoid valve 2 610 into the inside of the square groove 2 609 and the fixed groove 2 601, and then the gas will push the sealing plate 603 and the rack 604 to move, and the rack 604 will drive the gear 606 and the screw 607 to rotate, and the blocking block 608 will move on the surface of the screw 607, and then the blocking block 608 will enter the inside of the square groove 1 502, thereby blocking it, avoiding excessive pressure inside the fixed groove 1 501, affecting the normal operation of its internal components, and finally completing the operation process.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
