[0031] The outer wall of the second connecting pipe 302 is communicated with an inclined pipe 303, the inclined pipe 303 is distributed below the second connecting pipe 302 at a certain slope, a filter pipe 305 is installed on the inner wall of the inclined pipe 303, the holes opened on the filter pipe 305 are nanoscale and are distributed on the outer surface wall of the filter pipe 305, one end of the filter pipe 305 away from the inclined pipe 303 is fixedly connected to the inner wall of the second connecting pipe 302, and the liquid medicine enters the second connecting pipe 302 and is filtered to a certain extent through the filter pipe 305.
[0032] An inner cavity 304 is installed on the inner wall of the second connecting pipe 302. The inner cavity 304 is a kind of raised block connected to the outer wall of the filter pipe 305 to achieve a certain sealing effect. The inner wall of the inner cavity 304 is fixedly connected to the outer wall of the filter pipe 305. There are two inner cavities 304, symmetrically distributed centered on the second connecting pipe 302, used to connect the two sides of the filter pipe 305 to the inner wall of the second connecting pipe 302, so that the liquid medicine can only enter the liquid pump delivery end 1 after being filtered through the filter pipe 305.
[0033] One end of the second connecting pipe 302 away from the liquid pump delivery end 1 is attached to the first connecting pipe 301. At the connection between the first connecting pipe 301 and the second connecting pipe 302, connection blocks of the same size and material are installed for the connection between the first connecting pipe 301 and the second connecting pipe 302, and this connection block has a certain sealing effect.
[0034] The inner wall of the second connecting pipe 302 is threadedly connected with a first bolt 306. The first bolt 306 is threadedly connected with the first connecting pipe 301. There are multiple first bolts 306, and they are evenly distributed around the circumference of the connection block installed on the second connecting pipe 302, used for fixing between the first connecting pipe 301 and the second connecting pipe 302, and at the same time facilitating personnel to install and disassemble it.
[0035] A sealing device is provided between the connection of the first connecting pipe 301 and the second connecting pipe 302. One end of the second connecting pipe 302 is threadedly connected to the first connecting pipe 301 through the first bolt 306, and the other end of the second connecting pipe 302 is threadedly connected to the liquid pump delivery end 1 through the first bolt 306.
[0036] Refer to Figures 2-4 As shown in the figure, an auxiliary structure 4 is provided on the filtering structure 3. The auxiliary structure 4 includes a threaded block 403 threadedly connected to one end of the filter pipe 305 away from the second connecting pipe 302. By turning the threaded block 403, it is convenient to clean the impurities left inside the filter pipe 305. The inner wall of the threaded block 403 is rotatably connected with a rotating rod 404. The outer wall of the rotating rod 404 is rotatably connected through the inner wall of the threaded block 403. One end of the rotating rod 404 is located at the center position of the inner wall of the filter pipe 305, and the other end is located at the bottom position of the threaded block 403.
[0037] A connecting rod 405 is installed on the outer wall of the rotating rod 404. The connecting rod 405 is located at the exact center position inside the filter pipe 305. Multiple connecting rods 405 are distributed around the circumference of the rotating rod 404 on the rotating rod 404. When the rotating rod 404 rotates, it drives the connecting rod 405 to rotate. The connecting rod 405 drives the liquid medicine to rotate, improving the degree of fusion between the liquid medicines. At the same time, if the liquid medicine is not viscous, the impurities contained inside will remain on the threaded block 403 due to the action of physical gravity.
[0038] One end of the inclined tube 303 far from the second connecting tube 302 is provided with a motor 401. The output end of the motor 401 is connected to one end of the rotating rod 404 far from the connecting rod 405. When the motor 401 is started, the motor 401 drives the rotating rod 404 to rotate. The connecting rod 405 is located above the threaded block 403. One end of the connecting rod 405 far from the rotating rod 404 is equipped with a scraper 406. One side of the scraper 406 far from the connecting rod 405 is in contact with the inner wall of the filter tube 305. Each connecting rod 405 is equipped with a scraper 406. Under the rotation of the connecting rod 405, the liquid medicine or impurities contaminated on the inner wall of the filter tube 305 are scraped to a certain extent.
[0039] By the combined use of the rotating rod 404 and the connecting rod 405, the effect of stirring the liquid medicine is achieved, effectively mixing different components in the liquid medicine evenly, ensuring that the liquid medicine maintains a consistent concentration and composition distribution during transportation. And for some liquid medicines that need to undergo chemical reactions, stirring can accelerate the reaction rate. By stirring, the contact area between reactants can be increased, and the mass transfer resistance can be reduced, thereby promoting the progress of the reaction.
[0040] Stirring helps to accelerate the mass transfer process in the liquid medicine, such as the dispersion of gas in liquid, the dissolution of solid in liquid, etc. And by stirring, the formation of precipitates can be prevented, maintaining the fluidity and cleanliness of the liquid in the pump. In addition, in some cases, stirring can also help control the temperature of the liquid medicine. By stirring, the contact area between the liquid and the surrounding environment can be increased, promoting heat transfer and exchange, thereby realizing the regulation and control of temperature.
[0041] The output end of the motor 401 is equipped with a cross block 402. The outer wall of the cross block 402 is inserted into the inner wall of the rotating rod 404. Among them, the rotating rod 404 at the position connecting the cross block 402 is provided with a notch for inserting the cross block 402. By setting the cross block 402, the cross block 402 is inserted into the motor 401, which is convenient for personnel to disassemble and install the motor 401.
[0042] Start the liquid pump to suck the liquid medicine through the first connecting tube 301 into the interior of the second connecting tube 302. At this time, the liquid medicine enters the filter tube 305. Start the motor 401 to drive the cross block 402 to rotate. The cross block 402 drives the rotating rod 404 to rotate. The rotating rod 404 drives the connecting rod 405 and the scraper 406 to rotate. Under the rotation of the connecting rod 405 and the scraper 406, while improving the fusion degree of the liquid medicine, it can also filter certain impurities in the liquid medicine, effectively reducing problems such as equipment damage or performance degradation of the liquid medicine.
[0043] Refer to Figures 3-4, one end of the inclined tube 303 away from the second connecting tube 302 is inserted with a connecting plate 408. An outer wall of the connecting plate 408 is installed with a connecting member 2. An inner wall of the connecting member 2 is threadedly connected with a second bolt 5. An outer wall of the second bolt 5 is threadedly connected with an inner wall of the inclined tube 303. The number of the connecting members 2 is four and they are distributed equidistantly along the circumference of the connecting plate 408, and each connecting member 2 is distributed with a second bolt 5.
[0044] Insert the connecting plate 408 into one end of the inclined tube 303 away from the second connecting tube 302. At this time, an outer wall of the connecting member 2 is in contact with an outer wall of the inclined tube 303, and a hole on the connecting member 2 and a threaded hole on the inclined tube 303 are on the same horizontal plane. Then screw the second bolt 5 into the inside of the inclined tube 303 through the connecting member 2 to achieve the effect of fixing the connecting plate 408 on the inclined tube 303. Additionally, when aligning the hole on the connecting member 2 with the threaded hole on the inclined tube 303, the cross block 402 just engages with a notch opened on the rotating rod 404.
[0045] The outer wall of the connecting plate 408 is fixedly connected with an outer wall of the motor 401. An output end of the motor 401 is rotatably connected through an inner wall of the connecting plate 408. By providing the connecting plate 408, it is used to fix the motor 401 to a certain extent, which is convenient for improving the stability of the motor 401 during operation and thus improving the service life of the motor 401.
[0046] One side of the threaded block 403 away from the connecting rod 405 is installed with an abutting block 407. One side of the abutting block 407 away from the threaded block 403 is in contact with one side of the connecting plate 408 away from the motor 401. The number of the abutting blocks 407 is two and they are symmetrically distributed with the threaded block 403 as the center. By providing the abutting blocks 407, it is used to control the distance between the connecting plate 408 and the threaded block 403.
[0047] When the connecting plate 408 is inserted into the inclined tube 303, a top wall of the connecting plate 408 abuts against a bottom wall of the abutting block 407. At this time, just the outer wall of the connecting member 2 is in contact with the outer wall of the inclined tube 303. Additionally, through the two abutting blocks 407, it is convenient for personnel to unscrew the threaded block 403 from the filter tube 305. By providing the threaded block 403, it is convenient for personnel to clean the threaded block 403, the rotating rod 404, the connecting rod 405 and the scraper 406 to a certain extent.
[0048] When it is necessary to clean the filter tube 305, unscrew the second bolt 5, remove the motor 401 from the rotating rod 404, and then unscrew the threaded block 403 through the abutting block 407. At this time, it is possible to clean the impurities remaining inside the filter tube 305 to a certain extent, effectively improving the service life of the filter tube 305.
[0049] Working principle:
[0050] Start the liquid pump to suck the liquid medicine through the first connecting pipe 301 into the interior of the second connecting pipe 302. At this time, the liquid medicine enters the filter pipe 305. Start the motor 401 to drive the cross block 402 to rotate. The cross block 402 drives the rotating rod 404 to rotate, and the rotating rod 404 drives the connecting rod 405 and the scraper 406 to rotate. With the rotation of the connecting rod 405 and the scraper 406, while improving the fusion degree of the liquid medicine, it can also filter certain impurities in the liquid medicine, effectively reducing problems such as equipment damage or performance degradation of the liquid medicine.
[0051] When it is necessary to clean the filter pipe 305, unscrew the second bolt 5, remove the motor 401 from the rotating rod 404, and then unscrew the threaded block 403 through the abutting block 407. At this time, certain cleaning can be carried out on the impurities remaining inside the filter pipe 305, effectively improving the service life of the filter pipe 305.
