When using this device, the operator can control the progress and dosage of the drug addition process through the control panel, and can also observe the dosage through the metering dial on the metering pump. During the drug mixing process, the drug circulates between the two sets of storage cylinders through two sets of circulation pipes. The rotation of the connecting column will drive the scraper to rotate at the bottom of the storage cylinder, thereby scraping off the sediment at the bottom of the storage cylinder. This design utilizes the process of the drug flowing inside the device, which can not only scrape off the sediment at the bottom, but also the circulation itself can also make the drug mix evenly to a certain extent and avoid drug sedimentation.

[0014] 2. When the agent flows to the upper end in the circulation pipe, the flow of the agent will also drive the second rotating fan inside the circulation pipe to rotate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 7 This utility model provides an adjustable dosing machine, including a base plate 1 and two sets of bases 8 fixed to the top of the base plate 1. Two sets of storage cylinders 9 are fixedly installed at one end of each set of bases 8. A motor 2 is installed at the top of each set of storage cylinders 9, and a stirrer 6 rotates at one end of each motor 2. Two sets of metering pumps 3 are fixed to the top of the base plate 1. A control console 4 is fixedly installed to the top of the base plate 1. A circulation pipe 5 is fixedly connected to one side of each set of storage cylinders 9. A fixed bracket 10 is fixed to the top of the base plate 1. A first limiter 13 is installed at one end of the fixed bracket 10. A first rotating fan 11 rotates on one side of the first limiter 13. A track 14 is installed inside the first limiter 13. A second limiter 25 is provided at one end, and a connecting post 24 is rotatably connected to one end of the second limiter 25. A scraper 7 is fixedly connected to one end of the connecting post 24. A platform 16 is fixed to one side of the medicine storage cylinder 9. A liquid addition tank 15 is fixed to one end of the platform 16. A compression tube 19 is also fixed to one end of the platform 16. A threaded rod 22 rotates inside the compression tube 19. A sliding block 21 slides inside the compression tube 19. A rotating post 20 is fixed to one end of the threaded rod 22. A second rotating fan 12 is fixed to the outside of the rotating post 20. A spray pipe 17 is provided on one side of the liquid addition tank 15. The liquid addition tank 15 and the compression tube 19 are connected through a connecting pipe 18. An air inlet pipe 23 is provided on one side of the compression tube 19.

[0025] When using this device, the operator can control the progress and dosage of the dosing process through the control panel 4, and can also observe the dosing amount through the metering dial on the metering pump 3. During the mixing process, the agent will circulate between the two sets of storage cylinders 9 under the pressure of the water pump set at the lower end of the circulation pipe 5. When the agent flows between the circulation pipes 5, it will drive the first rotating fan 11 inside the circulation pipe 5 to rotate. The rotation of the first rotating fan 11 drives the track 14 to rotate between the first limiter 13 and the second limiter 25. At the same time, the rotation of the track 14 drives the connecting column 24 at the other end to rotate. The rotation of the connecting column 24 will drive the scraper 7 to rotate at the bottom of the storage cylinder 9, so as to scrape off the sediment at the bottom of the storage cylinder 9. This design utilizes the process of the agent flowing inside the device to not only scrape off the sediment at the bottom, but also the circulation itself can also make the agent mix evenly to a certain extent and avoid the agent sedimentation.

[0026] When the drug flows to the upper end in the circulation pipe 5, the drug flow will also drive the second rotating fan 12 inside the circulation pipe 5 to rotate. The rotation of the second rotating fan 12 drives the rotating column 20 and the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the sliding block 21 to slide up and down inside the compression pipe 19. The sliding block 21 presses down to compress the gas inside the compression pipe 19 through the connecting pipe 18 into the liquid addition tank 15. The liquid addition tank 15 stores a co-solvent. After the gas is compressed into the liquid addition tank 15, it will spray the co-solvent inside the liquid addition tank 15 into the drug storage cylinder 9 through the spray pipe 17. The co-solvent can help dissolve the precipitate inside the drug storage cylinder 9. This design can not only dissolve the precipitate scraped off the bottom of the drug storage cylinder 9, but also help the drug inside the drug storage cylinder 9 to mix evenly.

[0027] In an optional embodiment, the metering pump 3 is electrically connected to the control console 4 via a wire.

[0028] It should be noted that the operator can control the progress and dosage of the dosing process through the control console 4, and can also observe the amount of dosing through the metering dial on the metering pump 3.

[0029] In an optional embodiment, the first limiter 13 and the second limiter 25 are both gear-shaped and in mesh with the track 14, and the first rotating fan 11 and the second rotating fan 12 are both located inside the circulation pipe 5.

[0030] It should be noted that the rotation of the first rotating fan 11 drives the track 14 to rotate between the first limiter 13 and the second limiter 25, and the flow of the medicine also drives the rotation of the second rotating fan 12 inside the circulation pipe 5.

[0031] In an optional embodiment, the first limiter 13 and the second limiter 25 are rotatably connected to the track 14 via bearings, and the scraper 7 is in contact with the bottom of the medicine storage cylinder 9.

[0032] It should be noted that the rotation of the first rotating fan 11 drives the track 14 to rotate between the first limiter 13 and the second limiter 25. The rotation of the track 14 drives the connecting column 24 at the other end to rotate. The rotation of the connecting column 24 will in turn drive the scraper 7 to rotate at the bottom of the medicine storage cylinder 9.

[0033] In an optional embodiment, one end of the nozzle 17 is connected to the interior of the drug reservoir 9, and a one-way valve is provided inside the air inlet pipe 23.

[0034] It should be noted that when the sliding block 21 is pressed down, the gas will spray the co-solvent inside the liquid addition tank 15 into the storage cylinder 9 through the nozzle 17. When the sliding block 21 moves up, the gas inside the compression pipe 19 will be replenished from the outside to the inside through the air inlet pipe 23.

[0035] In an optional embodiment, the sliding block 21 and the threaded rod 22 are connected by a ball nut pair, and a sealing ring is provided at the bottom end of the sliding block 21.

[0036] It should be noted that when the threaded rod 22 rotates under the drive of the second rotating fan 12, the sliding block 21 will slide up and down along the thread on the surface of the threaded rod 22, and the sealing ring at the bottom of the sliding block 21 ensures the airtightness of the compression tube 19.

[0037] In an optional embodiment, a water pump is provided at one end of the circulation pipe 5.

[0038] It should be noted that the water pump installed at the lower end of the circulation pipe 5 pumps the medicine from the medicine storage cylinder 9 on one side to the medicine storage cylinder 9 on the other side. The two sets of circulation pipes 5 work together to form the circulation of the medicine.

[0039] Working principle: When using this device, the operator can control the process and dosage of the drug addition through the control panel 4, and can also observe the amount of drug added through the metering dial on the metering pump 3. During the drug mixing process, the drug will circulate between the two sets of storage cylinders 9 under the pressure of the water pump set at the lower end of the circulation pipe 5. When the drug flows between the circulation pipes 5, it will drive the first rotating fan 11 inside the circulation pipe 5 to rotate. The rotation of the first rotating fan 11 drives the track 14 to rotate between the first limiter 13 and the second limiter 25. At the same time, the rotation of the track 14 drives the connecting column 24 at the other end to rotate. The rotation of the connecting column 24 will drive the scraper 7 to rotate at the bottom of the storage cylinder 9.

[0040] When the agent flows to the upper end in the circulation pipe 5, the flow of the agent will also drive the second rotating fan 12 inside the circulation pipe 5 to rotate. The rotation of the second rotating fan 12 drives the rotating column 20 and the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the sliding block 21 to slide up and down inside the compression pipe 19. The sliding block 21 presses down to compress the gas inside the compression pipe 19 through the connecting pipe 18 into the liquid addition tank 15. The liquid addition tank 15 stores a co-solvent. After the gas is compressed into the liquid addition tank 15, it will spray the co-solvent inside the liquid addition tank 15 into the drug storage cylinder 9 through the nozzle 17.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
