[0021] According to the above structure, when feeding, aluminum fluoride is placed inside the storage bin 2, and aluminum fluoride is fed into the feeding chamber 13 through the bottom end of the storage bin 2, and then fed downward along the several feeding channels 14 on the side walls of the feeding chamber 13, and the electrolyte is pumped into the liquid inlet chamber 11. After the electrolyte reaches the top of the liquid inlet chamber 11, it flows downward along the changing channel 12. When aluminum fluoride is fed into the changing channel 12 from the bottom end of the feeding channel 14, it is mixed with the electrolyte inside the changing channel 12 and flushed out by the electrolyte inside the changing channel 12. The electrolyte flowing out of the changing channel 12 flows into the electrolytic cell, thereby bringing aluminum fluoride into the electrolytic cell, realizing the feeding of aluminum fluoride, avoiding the generation of dust by aluminum fluoride, and improving safety.
[0022] like Figure 3 and 4 As shown, the opening of the changing channel 12 is tilted downward, the angle between the changing channel 12 and the liquid inlet chamber 11 is 45°-60°, the angle between the discharge channel 14 and the feeding chamber 13 is 20°-30°, and a widening groove 17 is provided at the bottom of the discharge channel 14 and the connection point with the changing channel 12.
[0023] According to the above structure, when the electrolyte flows to the top of the liquid inlet chamber 11, it flows downward along the changing channel 12. The setting of the widening groove 17 widens the bottom end of the discharge channel 14, thereby increasing the contact area between aluminum fluoride and the electrolyte, thereby facilitating the mixing of aluminum fluoride and the electrolyte.
[0024] like Figure 4 As shown, a first baffle 15 inclined downward is provided inside the widening groove 17 , and a second baffle 16 inclined downward is provided inside the discharge channel 14 .
[0025] According to the above structure, the first separator 15 and the second separator 16 prevent the electrolyte from splashing upward, thereby preventing the electrolyte from flowing back into the interior of the feed channel 14 .
[0026] like Figure 3 As shown, the top end of the liquid inlet cavity 11 is a hemispherical structure, and the bottom end of the feeding cavity 13 is a conical structure.
[0027] According to the above structure, the setting of the liquid inlet chamber 11 can disperse the impact force of the electrolyte, and the setting of the feeding chamber 13 can make the aluminum fluoride evenly dispersed to the surroundings, so that it can be evenly fed downward along the plurality of feeding channels 14.
[0028] like Figure 2 As shown, the bottom end of the storage bin 2 is fixedly connected to a connecting pipe 21 , the bottom end of the connecting pipe 21 is fixedly connected to the top end of the feeding structure 1 , the connecting pipe 21 is connected to the feeding chamber 13 , and a valve 22 is fixedly installed on the connecting pipe 21 .
[0029] According to the above structure, the aluminum fluoride inside the storage bin 2 is fed downward through the connecting pipe 21, and the valve 22 plays the role of starting and stopping the feeding of aluminum fluoride.
[0030] The working principle of the present invention is as follows: when feeding, aluminum fluoride is placed inside the storage bin 2, and the aluminum fluoride inside the storage bin 2 is fed downwardly into the feeding chamber 13 through the connecting pipe 21. The valve 22 plays the role of starting and stopping the feeding of aluminum fluoride. The aluminum fluoride fed into the feeding chamber 13 is fed downwardly along the several feeding channels 14 on the side wall of the feeding chamber 13, and the electrolyte is pumped into the liquid inlet chamber 11 through the liquid inlet pipe 3. After the electrolyte reaches the top of the liquid inlet chamber 11, it flows downwardly along the changing channel 12. When the aluminum fluoride is fed into the changing channel 12 from the bottom end of the feeding channel 14, it is mixed with the electrolyte inside the changing channel 12 and is discharged by the electrolyte inside the changing channel 12. The liquid rushes out, and the electrolyte flowing out of the redirecting channel 12 flows into the electrolytic cell, thereby bringing aluminum fluoride into the electrolytic cell, realizing the feeding of aluminum fluoride, avoiding the generation of dust by aluminum fluoride, and improving safety. The setting of the widening groove 17 widens the bottom end of the feeding channel 14, increases the contact area between aluminum fluoride and the electrolyte, thereby facilitating the mixing of aluminum fluoride and the electrolyte. The first partition 15 and the second partition 16 prevent the electrolyte from splashing upward, and avoid the electrolyte from flowing back into the inside of the feeding channel 14. The setting of the liquid inlet chamber 11 can disperse the impact force of the electrolyte, and the setting of the feeding chamber 13 can make the aluminum fluoride evenly dispersed all around, so that it can be evenly fed downward along several feeding channels 14.
[0031] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
