At this time, the first motor (35) is started to rotate the spiral feeding rod (36) to inject the waste lithium battery fragments from which the electrolyte has been removed through the discharge pipe (37) to the top of the belt conveyor (11), and then the fragments are injected into the right end of the upper side of the guide plate (42) through the belt conveyor (11); S5：当去除电解液的废旧锂电池碎片移动到导流板（42）上侧的右端后启动所有电热管（14）使得安装箱（1）内部的温度上升，将废旧锂电池碎片中残留的电解液烘干，烘干后的废旧锂电池碎片向下被所有的破碎条（52）和两个破碎辊（62）再次粉碎；S5: After the waste lithium battery fragments from which the electrolyte has been removed move to the right end of the upper side of the guide plate (42), all the electric heating tubes (14) are started to increase the temperature inside the installation box (1) so as to dry the electrolyte remaining in the waste lithium battery fragments. The dried waste lithium battery fragments are crushed again downward by all the crushing bars (52) and the two crushing rollers (62); S6：再次粉碎后的废旧锂电池碎片向下移动到安装框（73）与储存框（71）之间，此时启动吹气扇（74）将废旧锂电池碎片中重量较轻的塑料膜吹到储存框（71）的内部，去除塑料膜的废旧锂电池碎片继续向下重新下落到第二过滤网板（85）的上，此时启动第四电机（91）使得凸轮（92）转动，凸轮（92）转动的过程中当其凸起部位与固定架（81）接触时将挤压固定架（81）向左移动，当凸轮（92）的凸起部位远离固定架（81）时固定架（81）将在两个弹簧（84）的作用下重新恢复到原来的位置，持续转动凸轮（92）将使得固定架（81）进行左右往复运动，从而使得第二过滤网板（85）进行左右往复运动对废旧锂电池碎片进行筛分，筛分后合格的废旧锂电池碎片向下移动到第一过滤网板（22）的上方，而未合格的废旧锂电池碎片向左通过上料组件（3）重新注入进U形架（41）的内部再一次进行破碎，直至所有的废旧锂电池碎片全部合格即可完成破碎；S6: The waste lithium battery fragments that have been crushed again move downward to between the installation frame (73) and the storage frame (71). At this time, the blowing fan (74) is started to blow the plastic film with a lighter weight in the waste lithium battery fragments into the interior of the storage frame (71). The waste lithium battery fragments without the plastic film continue to fall downward again onto the second filter plate (85). At this time, the fourth motor (91) is started to rotate the cam (92). During the rotation of the cam (92), when the raised portion of the cam (92) contacts the fixing frame (81), the fixing frame (81) is pressed to move to the left. When the raised portion of the cam (92) is away from the fixing frame (81), the fixing frame (81) is pressed to move to the left. When the cam (81) is rotated, the fixing frame (81) will return to its original position under the action of the two springs (84), and the cam (92) will continue to rotate to make the fixing frame (81) reciprocate left and right, thereby making the second filter screen (85) reciprocate left and right to screen the waste lithium battery fragments. After screening, the qualified waste lithium battery fragments move downward to the top of the first filter screen (22), while the unqualified waste lithium battery fragments are re-injected to the left through the feeding assembly (3) into the interior of the U-shaped frame (41) to be crushed again, until all the waste lithium battery fragments are qualified and the crushing is completed; S7：完成破碎后将储存箱（21）抽出，抽出后将位于第一过滤网板（22）上方的废旧锂电池碎片注入进热解炉进行高温热解，以使得有机粘结剂分解，得到完全热解正极片，进一步破碎后得到呈球形且粒度均匀的铝箔颗粒和正极活性粉末的正极片混合物料。S7: After the crushing is completed, the storage box (21) is pulled out, and after the extraction, the waste lithium battery fragments located above the first filter plate (22) are injected into the pyrolysis furnace for high-temperature pyrolysis, so that the organic binder is decomposed to obtain a completely pyrolyzed positive electrode sheet, and after further crushing, a positive electrode sheet mixture material of spherical aluminum foil particles and positive electrode active powder with uniform particle size is obtained.
