[0028] Working principle: After the lithium carbonate raw material is put into the crushing box 2, the large pieces of raw material can be crushed into small pieces by the collision between the crushing rod 11 and the crushing block 10 inside the crushing box 2. Due to the obstruction of the screen plate 9, the raw material will fall into the screen box 7 below after being crushed to a small enough size. The screen box 7 forms a sufficiently effective screening effect by moving back and forth, and can screen out the raw material particles that accidentally fall and do not meet the set particles and flow them out of the crushing box 2.

After the solvent reaction is complete, the valve 28 in the water pipe 27 is opened to allow the lithium carbide solution that has reacted completely to be output to the rear for use. After the solution is completely discharged, the valve 28 inside the water pipe 27 is closed to proceed to the next round of dissolution process. After multiple uses, in order to avoid solid crystals precipitating inside the dissolution box 3, the lower valve 28 is opened to supply water to the water pipe 3 29 to allow the cleaner 30 to work. After cleaning is completed, the water supply to the water pipe 3 29 is stopped and the cleaning work is completed after the cleaning water is exhausted.
