[0021] Now, the present utility model will be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] As Figure 1 and Figure 2 shown, a drug concentration purification tank includes: a stirring assembly and a cleaning assembly arranged in the tank body 1. A pressure sensor 2 and a temperature sensor 3 are arranged inside the tank body 1, and a jacket layer 4 is arranged inside the outer wall of the tank body 1. The jacket layer 4 communicates with the inlet air pipe 5 and the exhaust pipe 6. The circulating steam enters the jacket layer 4 through the inlet air pipe 5 and is discharged from the exhaust pipe 6 to heat the liquid medicine in the tank body 1. An exhaust passage 21 is arranged at the upper part of the tank body 1, and the exhaust passage 21 is connected to the gas treatment process, and the steam is discharged through the exhaust passage 21.

[0023] As Figure 3As shown in the figure, the stirring assembly includes a stirring shaft 7 coaxially arranged in the tank body 1. A number of groups of stirring blades 8 are arrayed in the middle part of the stirring shaft 7, and a number of spiral scraping plates 9 are arrayed in the lower part of the stirring shaft 7. The bottom surfaces of the number of spiral scraping plates 9 are attached to the inner wall of the bottom of the tank body 1. An assembly plate is arranged at the upper part of the tank body 1, a driving device 19 is arranged on the top surface of the assembly plate, the output end of the driving device 19 is connected to the stirring shaft 7. The lower part of the tank body 1 is conical, a discharge pipe 22 is arranged at the lower part of the tank body 1. The lower end of the stirring shaft 7 is connected to a rotating shaft 17, and a spiral pushing blade 18 is arranged on the outer peripheral side of the rotating shaft 17. When the driving device 19 drives the stirring shaft 7 to rotate forward, the spiral pushing blade 18 lifts the medicine in the discharge pipe 22 to make it participate in the stirring and mixing, and cooperates with the stirring blades 8 to effectively improve the mixing efficiency of the medicine during heating. On the other hand, an arc-shaped scraping plate 15 is arranged at the upper part of the stirring shaft 7, the bottom surface of the arc-shaped scraping plate 15 is attached to the top surface of the filter plate 14. When the driving device 19 drives the stirring shaft 7 to rotate reversely, the spiral scraping plate 9 scrapes the inner wall of the bottom of the tank body 1, and at the same time the spiral pushing blade 18 quickly conveys the medicine through the discharge pipe 22.

[0024] In a preferred embodiment of the present invention, a number of the stirring blades 8 are spiral. When a number of groups of stirring blades 8 stir the medicine, since the spiral directions of the two groups of stirring blades 8 symmetrically arranged with respect to the stirring shaft 7 are opposite, a certain shear flow will be formed for the medicine in the tank body 1, further improving the medicine mixing efficiency, accelerating the heat transfer of the medicine in different regions, and thus increasing the medicine concentration purification efficiency.

[0025] As Figure 4 shown, the cleaning assembly includes an annular infusion pipe 10 coaxially arranged in the tank body 1. The infusion pipe 10 is communicated with a water pump through a water inlet pipe. The infusion pipe 10 is connected to the inner wall of the tank body 1 through a number of assembly rods 11. A number of drain pipes 12 are arrayed at the bottom of the infusion pipe 10. The bottom of the drain pipe 12 is rotatably connected to a cleaning spray head 13. The cleaning spray head 13 is spiral. When flushing the inner wall of the tank body 1, a cleaning liquid is conveyed into the infusion pipe 10 through an air pump, and the cleaning liquid is sprayed from the cleaning spray head 13 onto the inner wall of the tank body 1. When the spiral cleaning spray head 13 sprays water, the sprayed cleaning liquid will generate a certain reaction force on the cleaning spray head 13, causing the cleaning spray head 13 to rotate relative to the drain pipe 12 continuously, so that the cleaning spray head 13 can rotate and clean the tank wall by itself without external power, and the overall structural design is more reasonable.

[0026] In a preferred embodiment of the present invention, a spherical filter plate 14 is arranged at the upper part of the tank body 1, a slag discharge window 16 is arranged at the upper part of the tank body 1, and the slag discharge window 16 is arranged on one side of the filter plate 14. The medicine residue in the previous process is filtered by the filter plate 14, and the residue is separated from the slag discharge window 16 under the scraping of the arc-shaped scraping plate 15. The medicine passes through the filter plate 14 and enters the lower part of the tank body 1, effectively improving the purity of the medicine concentration purification.

[0027] When the utility model is in use, materials are conveyed to the upper part of the tank body 1 through the feeding pipe 20. After being filtered by the filter plate 14, residues and other impurities in the medicine will remain above the filter plate 14, and the medicine enters the lower part of the tank body 1. The circulating steam enters the jacket layer 4 through the air inlet pipe 5 and is discharged from the exhaust pipe 6 to heat the liquid medicine in the tank body 1. At the same time, the driving device 19 drives the stirring shaft 7 to rotate forward, and the spiral pushing blade 18 lifts the medicine in the discharge pipe 22 to make it participate in stirring and mixing, and cooperates with the stirring blade 8 to stir the medicine until the concentration and purification of the medicine are completed. When it is necessary to discharge the medicine, the driving device 19 drives the stirring shaft 7 to rotate reversely, the spiral scraper 9 scrapes the inner wall of the bottom of the tank body 1, and at the same time the spiral pushing blade 18 quickly discharges the medicine through the discharge pipe 22 into the next process.
