However, the existing cleaning methods are too cumbersome and complicated, the cleaning effect is poor, and the cleaning is not thorough enough.

[0031] A water storage tank 6 is fixed to the outer side wall of the barrel body 1. A cleaning assembly 7 adapted to the hollow shaft 4 is provided on one side of the barrel body 1. A discharge pipe 8 connected to the interior is fixed on one side of the barrel body 1;

[0032] It should be noted that when the cleaning component 7 is used to clean the barrel body 1 after the mixing is completed, the barrel body 1 is cleaned with a chemical reagent to achieve the purpose of cleaning the barrel body 1 after the mixing is completed. This is a conventional setting in the art, so it will not be described in detail here.

[0033] It should also be noted that two symmetrically distributed feed pipes 12 are fixed to the top side wall of the barrel body 1, and the other end of the feed pipe 12 is connected to the interior of the barrel body 1. A support frame 13 is fixed to the bottom side wall of the barrel body 1. By arranging two feed pipes 12 at the barrel body 1, it is convenient for the staff to add sodium carbonate into the barrel body 1 in time, which can improve the mixing effect of the mixing work.

[0034] Further as Figure 3 and Figure 4 As shown, it is worth mentioning that the stirring assembly 5 includes a transmission frame 51, which is tightly sleeved on the outer side wall of the hollow shaft 4. A plurality of transmission shafts 52 distributed in a circumferential manner are rotatably connected to one side wall of the transmission frame 51.

A plurality of stirring rods 53 distributed in a circumferential manner are fixed to the outer side wall of the transmission shaft 52.

[0035] Among them, by setting one end of the transmission shaft 52 in the annular guide groove 9 as a chamfered inclined surface, the smoothness of the transmission shaft 52 during operation can be improved, and the transmission shaft 52 can be effectively prevented from getting stuck during operation.

The projected area value of the bottom plate 15 is greater than the projected area value of the barrel body 1. The bottom plate 15 is arranged in a circular shape, and the bottom plate 15 can effectively form a support role for the support frame 13 and the barrel body 1, thereby greatly improving the stability of the entire device during use;

[0039] Water pipe b74, the other end of water pipe b74 is fixed to the output end of water pump 72, one end of hollow shaft 4 extends to the outside of barrel body 1 in the vertical direction, one end of water pipe b74 extends to the inside of hollow shaft 4, and the outer side wall of hollow shaft 4 is provided with multiple through holes 75 distributed in a circumference.

[0040] It should be noted that the central axis of the output end of the water pipe b74 is collinear with the central axis of the hollow shaft 4 to ensure that the two are on the same straight line. In addition, the material of the water pipe b74 is specially selected as a metal hard material. This material has high strength and rigidity, ensuring that under pressurization, the chemical reagents can be stably and smoothly transported to the inside of the hollow shaft 4, making it convenient for the staff to clean the barrel body 1, and preventing the occurrence of chemical reactions due to incomplete cleaning, thereby greatly improving the quality of the next mixing of sodium carbonate and lithium mother liquor, and significantly improving the cleaning effect of the barrel body 1.

[0041] This solution has the following working process: when sodium carbonate and lithium mother liquor need to be mixed, the working principle of mixing sodium carbonate and lithium mother liquor is as follows:

[0042] First, a quantitatively proportioned sodium carbonate and lithium mother liquor are fed into the barrel 1 through the feed pipe b. After the material feeding is completed, an appropriate amount of sodium carbonate can be added into the barrel 1 through the feed pipe b;

[0043] Secondly, the servo motor 3 drives the hollow shaft 4 to rotate, driving the transmission frame 51 to rotate synchronously, and then drives the multiple transmission shafts 52 to rotate synchronously, causing the spur gears 55 to rotate synchronously. The meshing transmission between the spur gears 55 and the toothed ring 54 enables the transmission shaft 52 to rotate during its circular motion, driving the stirring rod 53 to rotate synchronously, and the stirring rod 53 is used to fully mix the sodium carbonate and lithium mother liquor in the barrel 1;

[0044] Then, after the sodium carbonate and lithium mother liquor are mixed, they need to be discharged to the next process for processing and discharged from the discharge pipe 8;

[0045] Finally, when the barrel body 1 needs to be cleaned after the mixing work is completed, the chemical reagent in the water tank 6 is pressurized by driving the water pump 72, and the pressurized chemical reagent is output to the hollow shaft 4 through the water pipe b74, and then the barrel body 1 is spray-cleaned, and then the cleaning work inside the barrel body 1 is completed.

[0046] The servo motor 3 and the water pump 72 can both be purchased on the market. Both the servo motor 3 and the water pump 72 are equipped with power supplies. They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
