[0027] The utility model is further described below in conjunction with embodiments.
[0028] Embodiment 1:
[0029] See also Figure 1-Figure 7 The dialysis membrane 74 is provided with three groups, and the outer surfaces of the three groups of dialysis membranes 74 are all provided with dialysis holes 741, and the size of the dialysis holes 741 decreases from top to bottom. The three groups of dialysis membranes 74 filter pollutants step by step, so as to improve the filtering efficiency.
[0030] The bottom of the glass conical bottle 6 is fixedly connected with a liquid outlet pipe 8, and the outer surface of the liquid outlet pipe 8 is fixedly connected with a valve 81, and the liquid outlet pipe 8 is connected to the bottom of the filter barrel 2. The valve 81 is convenient for controlling the flow rate of doxycycline hydrochloride for injection. When the valve 81 is opened, the filtered doxycycline hydrochloride for injection flows out through the liquid outlet pipe 8.
[0031] The inner wall of the filter barrel 2 is fixedly connected with an ultraviolet sterilization lamp 21, the bottom end of the filter barrel 2 is fixedly connected with a motor 9, the output end of the motor 9 is fixedly connected with a rotating rod 91, the top of the rotating rod 91 is fixedly connected with a driving wheel 92, the outer surface of the liquid outlet pipe 8 is fixedly connected with a driven wheel 82, the driving wheel 92 is meshed and linked with the driven wheel 82, and the rotating rod 91 is connected through the bottom end of the filter barrel 2. The ultraviolet sterilization lamp 21 can penetrate the glass cone 6 for disinfection, start the motor 9, the motor 9 drives the rotating rod 91 to rotate, the rotating rod 91 drives the driving wheel 92 to rotate, the driving wheel 92 rotates and drives the driven wheel 82 to rotate, thereby driving the glass cone 6 to rotate, and the rotation of the glass cone 6 facilitates the ultraviolet sterilization lamp 21 to sterilize the glass cone 6 in all directions.
[0032] An activated carbon filter 51 is provided inside the transmission air pipe 5. The activated carbon filter 51 is used to filter particulate pollutants in the air to prevent the pollutants from entering the filter barrel 2 and affecting the filtering effect.
[0033] The top of the filter barrel 2 is provided with a sealing cover 22, and a through opening 223 is provided at the top of the sealing cover 22. A sealing plug 221 is movably connected inside the through opening 223. The sealing cover 22 is opened to facilitate taking out the filter assembly 7, and the sealing plug 221 is opened, and the doxycycline hydrochloride for injection enters the glass conical bottle 6 through the through opening 223 for filtration.
[0034] A first sealing gasket 52 is fixedly connected at the connection between the transmission air pipe 5 and the filter barrel 2, and a second sealing gasket 222 is fixedly connected at the connection between the sealing plug 221 and the sealing cover 22. The first sealing gasket 52 and the second sealing gasket 222 strengthen the sealing of the entire device to prevent external bacteria from entering.
[0035] The outer surface of the filter barrel 2 is fixedly connected with an annular support frame 23, and the bottom end of the annular support frame 23 is fixedly connected with a support leg 231, and the support leg 231 is fixedly connected to the base 1.

The rotation of the glass conical bottle 6 is convenient for the ultraviolet sterilization lamp 21 to sterilize the glass conical bottle 6 in all directions. After the sterilization is completed, the sealing plug 221 is unscrewed, and the doxycycline hydrochloride for injection enters the interior of the glass conical bottle 6 through the opening 223, and then the sealing plug 221 is screwed on, and the air pump 3 is started. Under the action of the air pump 3, the outside air is filtered by the activated carbon filter device 51 arranged inside the transmission air pipe 5 and then enters the inside of the filter barrel 2, so that the internal air pressure of the filter barrel 2 is higher than the external air pressure, so as to prevent pollutants in the air from entering the inside of the filter barrel 2. The doxycycline hydrochloride for injection filters the pollutants step by step through the three groups of dialysis membranes 74. After the filtration is completed, the valve 81 is opened, and the filtered doxycycline hydrochloride for injection flows into the sterile collection barrel 4 through the liquid outlet pipe 8 for collection. When the dialysis membrane 74 needs to be replaced, the sealing cover 22 is opened, and the handle 75 is pulled to move the handle 75 upward. The upward movement of the handle 75 drives the mounting frame 72 upward, thereby driving the slide bar 71 to slide upward inside the slide groove 61, so as to facilitate the removal of the filter assembly 7 from the glass conical bottle 6. The dialysis membrane 74 is flexibly connected to the mounting groove 73 to facilitate the replacement of the contaminated dialysis membrane 74.
