[0024] Example

[0025] This embodiment provides a soft capsule-filled drug filtration device; see [link to relevant documentation]. Figure 1 The device includes a support 1 and a main body box 2 mounted on it. The main body box 2 is equipped with a filter mechanism 3 inside. The filter mechanism 3 is connected to a feed pipe 4 extending to the outside of the main body box 2. The lower side of the main body box 2 is also equipped with a medicine storage box 5. The filter mechanism 3 is connected to the medicine storage box 5, and a discharge pipe 6 is connected to one side of the medicine storage box 5. The medicine can be pumped into the filter mechanism 3 through the feed pipe 4. After filtration by the filter mechanism 3, the clean medicine without particulate impurities can be concentrated in the medicine storage box 5. By connecting the spray nozzle and the discharge pipe 6, the medicine in the medicine storage box 5 can be injected into the soft capsule, effectively avoiding the clogging of the spray nozzle. The structure of the filter device (the above-mentioned soft capsule filling medicine filter device) is described in detail below with reference to the accompanying drawings.

[0026] In this embodiment, combined with Figure 2 and Figure 3 As the core technical concept of this utility model, since the medicine usually has a certain viscosity, in order to ensure the filtration efficiency of the filtration mechanism 3, the structure of the filtration mechanism 3 includes a vertically arranged columnar filter cylinder 31. The upper side of the filter cylinder 31 is connected to the pressure filter piston unit 33 through the drive unit 34. The middle part of the filter cylinder 31 is also provided with a filter screen unit 39. The upper outer side of the filter cylinder 31 is provided with a feed branch pipe 35 that connects the filter cylinder 31 and the feed main pipe 4, and the lower end is provided with a discharge branch pipe 38 that connects to the medicine storage tank 5. Based on this structure, the medicine to be filtered can be added into the filter cylinder 31 through the feed main pipe 4 and the feed branch pipe 35. The drive unit 34 drives the action of the pressure filter piston unit 33 to press the medicine into the medicine storage tank 5 through the discharge branch pipe 38. During the transfer of the medicine, the filter screen unit 39 completes the filtration of the medicine, preventing incompletely dissolved components or other insoluble impurities in the medicine from clogging the nozzle and ensuring that the medicine injection of the soft capsule can be carried out smoothly.

[0027] Specifically, regarding the cooperation structure between the filter press piston unit 33 and the filter cartridge 31, the filter cartridge 31 has a through hole in the middle of its upper side, and a guide cylinder 32 is vertically arranged on the upper side of the filter cartridge 31 corresponding to the through hole. The filter press piston unit 33 includes a guide post 331 vertically arranged in the through hole. The upper end of the guide post 331 is slidably arranged in the guide cylinder 32, and the lower end is located in the filter cartridge 31 and is horizontally connected to a circular piston plate 333 that cooperates with the inner ring of the filter cartridge 31. By driving the guide post 331 to move, the piston plate 333 can be moved to complete the pressing of the agent.

[0028] Specifically, the drive structure of the drive unit 34 includes a telescopic motor vertically disposed outside the guide cylinder 32. The guide cylinder 32 is vertically provided with a strip-shaped sliding opening. The guide post 331 is provided with a connector 332 extending out of the sliding opening on one side. The drive unit 34 also includes a vertically disposed connecting rod, and the telescopic motor is connected to the connector 332 of the filter press piston unit 33 through the connecting rod.

[0029] As a preferred embodiment of this invention, in order to prevent excessive pressure from the filter piston unit 33 from damaging the structure of the filter screen plate 393, and to ensure the filtration efficiency of the agent under the action of the filter piston unit 33, a sensor (not shown) is provided in the middle of the connecting rod to detect the driving force of the telescopic motor in real time. Through the sensor, the magnitude of the driving force of the filter piston unit 33 by the drive motor 391 can be detected in real time.

[0030] Combination Figure 4 Specifically, the filter unit 39 includes a circular filter screen plate 393 that is horizontally rotatably disposed within the filter cylinder 31. The filter screen plate 393 is connected to a drive motor 391 that drives it to rotate. During the pressure filtration of the pharmaceutical agent, the drive motor 391 drives the filter screen plate 393 to rotate, thereby agitating the pharmaceutical agent to be filtered at the bottom layer. This prevents incompletely dissolved components or other insoluble impurities in the pharmaceutical agent from clogging the filter screen plate 393, ensuring that the pressure filtration can proceed more smoothly.

[0031] In a preferred embodiment of this invention, to facilitate the replacement of the filter screen 393 and to ensure the stability of the filter screen 393 under pressure during the filtration process, the drive motor 391 is located in the middle of the filter cylinder 31 with the drive axis pointing upwards, and the motor body is connected to the inner wall of the filter cylinder 31 through the connecting rib 392. The inner ring of the middle part of the filter cylinder 31 is provided with a protruding annular platform, and the filter screen 393 is placed on the annular platform and inserted and snapped into the drive shaft of the drive motor 391 in the middle.

[0032] As a further preferred embodiment, in order to ensure the structural strength of the filter screen plate 393 and prevent damage caused by pressure during the filtration process, thereby ensuring that the filtration process can proceed smoothly, the filter screen plate 393 includes a circular outer ring frame and a connecting seat in the middle. Several reinforcing ribs are circumferentially connected between the connecting seat and the inner ring of the outer ring frame, and a filter cloth is provided between two adjacent reinforcing ribs.

[0033] In this embodiment, to ensure that the agent can be smoothly added into the filter cartridge 31 through the feed pipe 35, an exhaust pipe 36 communicating with the inside of the filter cartridge 31 is also provided on the outer side of the upper end of the filter cartridge 31. The exhaust pipe 36 is equipped with a switch valve. Based on this structure, when the agent is added into the filter cartridge 31 through the feed pipe 35, the pressure inside the filter cartridge 31 can be balanced by opening the switch valve, ensuring that the agent can be smoothly injected into the filter cartridge 31.

[0034] Furthermore, an air inlet pipe 37 is provided on the outer side of the middle part of the filter cartridge 31, and on the lower side of the filter screen plate 393, which connects to the inside of the filter cartridge 31. The air inlet pipe 37 is equipped with a switch valve. Based on this structure, when the filter press piston unit 33 rises under the drive unit 34 after one filter press is completed, the switch valve can be opened to ensure that the filter press piston unit 33 moves smoothly upward. When the filter press piston unit 33 rises, the airflow entering from the air inlet pipe 37 can blow upward from the lower side of the filter screen plate 393, thereby blowing out the insoluble impurities that are blocked in the mesh of the filter screen plate 393, ensuring that the next filter press can be carried out smoothly.

[0035] In this embodiment, in order to ensure that the filtration operation of the filtration device can match the liquid injection and forming operation of the soft capsule and to ensure the supply of clean medicine, multiple sets of filtration mechanisms 3 are arranged in parallel. The feed pipes 35 of the multiple sets of filtration mechanisms 3 are all connected to the feed main pipe 4, and the discharge pipes 38 are connected to the medicine storage tank 5.
