For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0021] Please refer to Figure 1-7 , the embodiments of the present application provide a technical solution: a drug preparation and purification device, including an equipment rack 1, a main body mechanism 2, a pressure regulating mechanism 3, a condensation mechanism 4, a steam pipe 8, and two one-way valves 7. The main body mechanism 2 includes a purification tank 201. The top of the purification tank 201 is provided with a feeding port 202. Inside the purification tank 201, there are a temperature sensor, a water level sensor, and a pressure sensor, which significantly improve the accuracy, safety, and automation level of the process. The temperature sensor monitors the heating process in real time to avoid the decomposition of active ingredients or the combustion and explosion of solvents. The water level sensor prevents dry burning and automatically adjusts the solvent amount to ensure the extraction efficiency. The pressure sensor monitors the pressure change in the closed system to ensure operation safety and optimize the separation effect. The three work together to achieve precise temperature control, prevent misoperation, save energy and reduce consumption, and at the same time provide support for data traceability and automatic control in the pharmaceutical process. An exhaust port 203 is provided at the top of the purification tank 201, a liquid return port 204 is provided on one side of the purification tank 201, a heating component 205 is fixedly installed inside the purification tank 201. Drugs and solvents are added through the feeding port 202, and the solvents and medicinal materials are heated by the heating component 205 to dissolve the available components in the medicinal materials in the solvents, completing the purification operation. One set of one-way valves 7 is fixedly connected to the top of the exhaust port 203, and the other set of one-way valves 7 is fixedly connected to one side of the liquid return port 204. The two sets of one-way valves 7 are fixedly connected to both ends of the steam pipe 8. The steam generated during the purification process enters the interior of the steam pipe 8 through the exhaust port 203, is condensed by the condensation mechanism 4, and then returns to the interior of the purification tank 201 through the liquid return port 204. During this process, the flow direction of the steam is determined by the one-way valve 7; The pressure regulating mechanism 3 includes a pressure regulating tank 301. An installation rod 302 is slidably installed inside the pressure regulating tank 301. A piston disc 303 is fixedly connected to the bottom of the installation rod 302. A sealing ring 307 is sleeved on the outer wall of the piston disc 303. The sealing ring 307 ensures the sealing between the piston disc 303 and the pressure regulating tank 301. A spring 304 is sleeved on the outer wall of the installation rod 302. A first connection head 305 is provided at the bottom of the pressure regulating tank 301, and a second connection head 306 is provided at the bottom of the pressure regulating tank 301. The pressure regulating tank 301 is fixedly connected to the interior of the steam pipe 8 through the first connection head 305 and the second connection head 306. During the heating and purification process, the air pressure inside the equipment will increase. When the air pressure is high, the steam will cause the piston disc 303 to move upward against the elastic force of the spring 304, allowing the gas to enter the interior of the pressure regulating tank 301. When the air pressure is stable, the air inside the pressure regulating tank 301 will return to the interior of the steam pipe 8 under the action of the spring 304. The pressure regulating mechanism 3 balances the air pressure to prevent the air pressure inside the equipment from getting out of balance; The condensation mechanism 4 includes a condensation box 401. Inside the condensation box 401, a condensation pipe 403 is fixedly installed. The condensation pipe 403 is fixedly connected inside the steam pipe 8. On one side inside the condensation box 401, a refrigeration component 402 is fixedly installed. One side of the refrigeration component 402 is fixedly connected to a cooling pipe 405. The cooling pipe 405 is arranged inside the condensation box 401. A number of heat conduction fins 404 are fixedly installed on the outer walls of the refrigeration component 402 and the cooling pipe 405. Through the heat conduction fins 404, the heat exchange efficiency of the refrigeration component 402 and the cooling pipe 405 is ensured. A heat exchange medium is arranged inside the condensation box 401, and a refrigeration medium is arranged inside the cooling pipe 405. The refrigeration component 402 cools the refrigeration medium inside the cooling pipe 405 and makes the refrigeration medium circulate inside the cooling pipe 405. Then, the temperature of the heat exchange medium inside the condensation box 401 is reduced through the cooling pipe 405. In summary, when steam enters the inside of the condensation pipe 403 through the steam pipe 8, it condenses under the action of the heat exchange medium, and then enters the inside of the purification tank 201 through the steam pipe 8, the one-way valve 7, and the liquid return port 204. The pressure regulating mechanism 3, the condensation mechanism 4, and the main body mechanism 2 are all fixedly installed on the top of the equipment rack 1.

[0022] In this solution, the steam generated during purification is condensed through the cooperation among the one-way valve 7, the steam pipe 8, and the condensation mechanism 4 and then flows back into the inside of the main body mechanism 2, significantly improving the recycling utilization rate of the solvent, reducing raw material loss and production costs. At the same time, the pressure regulating mechanism 3 maintains the air pressure balance of the purification system, ensuring the stability of process parameters and the consistency of extraction efficiency, and can also effectively reduce the emission of volatile substances, solving the problem in the prior art that in the drug preparation and purification equipment, the steam generated during the heating and purification process is directly discharged. The steam contains valuable chemical components or solvents, increasing production costs and causing waste of resources.

[0023] Please refer to Figure 8, the present invention provides a technical solution: a drug preparation and purification device, further comprising a cleaning mechanism 5. The cleaning mechanism 5 includes a connecting flange 501 fixedly installed on the top of the purification tank 201. A connecting pipe 502 is slidably installed inside the connecting flange 501. A main liquid supply pipe 503 is provided at the top of the connecting pipe 502, and a secondary liquid supply pipe 504 is provided on one side of the connecting pipe 502. An installation frame 505 is fixedly installed on the top of the connecting flange 501. A first motor 506 is fixedly installed on the top of the installation frame 505. The bottom of the output shaft of the first motor 506 is fixedly connected to a screw rod 507 through a coupling. The screw rod 507 is rotatably installed inside the installation frame 505. A slider 508 is threadedly connected to the outer wall of the screw rod 507. The bottom of the connecting pipe 502 is fixedly connected to a spray rod 509. The bottom of the spray rod 509 is rotatably installed with an installation head 514. A spray disc 510 is rotatably installed on one side of the installation head 514. A number of spray heads 511 are equiangularly installed on the outer wall of the spray disc 510. The extension line of the axis of the spray head 511 does not intersect with the center of the spray disc 510. A first bevel gear 512 is sleeved on the outer wall of the spray rod 509. A second bevel gear 513 is fixedly installed on one side of the spray disc 510. The second bevel gear 513 is meshed and connected to one side of the first bevel gear 512. The flushing liquid is provided through the main liquid supply pipe 503, and the cleaning agent is provided through the secondary liquid supply pipe 504. After the two are mixed, they enter the inside of the spray rod 509 through the connecting pipe 502, and then are sprayed out from the end of the spray head 511. Because the extension line of the axis of the spray head 511 does not intersect with the center of the spray disc 510, the spray disc 510 will rotate self-driven under the reaction force of the spray head 511 after the mixed liquid is sprayed out. Then, under the cooperation between the first bevel gear 512 and the second bevel gear 513, the installation head 514 rotates around the center of the spray rod 509. Further, through the cooperation among the installation frame 505, the screw rod 507, and the slider 508, when the first motor 506 operates, it can drive the spray rod 509 to move up and down inside the purification tank 201. In summary, when the cleaning mechanism 5 operates, the spray head 511 can move up and down inside the purification tank 201 while rotating around the center of the spray disc 510 and rotating around the center of the spray rod 509, spraying the cleaning mixed liquid evenly onto the inner wall of the purification tank 201 to clean the inner wall of the purification tank 201. In summary, this device can efficiently clean the inner wall of the purification tank 201 through the cleaning mechanism 5, can thoroughly remove the residual drug components and impurities in the tank, effectively avoid cross-contamination; significantly improve the cleaning efficiency and reduce the equipment downtime; at the same time reduce the manual cleaning intensity and safety risks.

[0024] Please refer to Figure 1-4, the present invention provides a technical solution: a drug preparation and purification device, which further includes a discharging mechanism 6.

The transmission rod 605 is rotatably installed inside the sealing cover 601 and the filter screen 603. A number of stirring claws 606 are fixedly installed at the top of the transmission rod 605. During the purification process, the second motor 604 drives the transmission rod 605 to rotate, and then the solvent and medicinal materials are stirred by a number of stirring claws 606. After the purification is completed, the purified liquid is discharged through the liquid discharge valve 602. During this process, the purified liquid is filtered by the filter screen 603 to prevent the medicinal residues from being discharged. When the purified liquid is completely discharged, the sealing cover 601 is rotated and the medicinal residues can be discharged from the bottom of the purification tank 201. In summary, during the purification of this equipment, the medicinal materials and the solvent can be fully mixed by stirring, enhancing the dissolution rate and extraction uniformity of the active ingredients. The liquid medicine and medicinal residues are convenient to discharge, greatly reducing the difficulty of manual cleaning and improving the production efficiency.
