As shown in fig. 1, the processing aid 32 is a mixture of sand and iron particles. When sand grains and iron grains are mixed with the waste batteries with the cut-out flow-discharging openings, on one hand, part of the sand grains and the iron grains enter the battery core to accelerate drying inside the battery core, and the sand grains or the iron grains can rub dried electrolyte and electrode plate coating layers in the battery core in the process of entering and exiting the battery core, so that the dried and solidified electrolyte and electrode plate coating layers can be scraped into powder; on the other hand, when the liquid electrolyte flows out, more sand grains and iron grains are contacted, but the converter 3 is not turned over, so that the electrolyte is prevented from being excessively adhered to drying equipment, and the recovery rate is reduced; and finally, the iron particles are in the waste battery mixing process, so that the batteries are subjected to micro short circuit, the discharge of the batteries is realized, and the discharge of the batteries is realized in the drying process.

When the processing auxiliary material 32 is used specifically, the processing auxiliary material 32 is added from the auxiliary material adding pipe 31, and the processing auxiliary material 32 in this embodiment is sand and iron particles. Then, the material valve 9 of the auxiliary material addition pipe 31 is closed. Then, the added nitrogen is introduced from the air inlet 5 of the left supporting shaft 2, and the heated nitrogen heats the sand grains and the iron grains in the tilting furnace 3 through heat transfer on one hand, and on the other hand, the nitrogen enters the top cover at the top end of the box body 1 from the hopper 12. The spent batteries are relatively neatly stacked into the feed hopper 16 and, to improve efficiency, special material transfer equipment may be used to align the spent batteries in the same orientation before feeding into the feed hopper 16. The waste batteries in the feed hopper 16 are continuously fed into the top cover 17 by the conveyor 15 from the through slots 1701 in the side wall of the top cover 17 under the action of the conveyor. The batteries entering the top cover 17 are limited by a pressure plate 27 above and prevented from stacking, and the batteries encounter an inclined guide plate 29 during the transportation to the circular saw blade 19, and the guide plate 29 can make the waste batteries move towards the circular saw blade 19 and finally contact the baffle plate 23 to be aligned at one end of the baffle plate 23.

The aligned waste batteries are continuously conveyed towards the circular saw blade 19, the end of the arc-shaped tilting 2701 of the pressing plate 27 enters the pressing plate 27, and the compression spring 26 arranged at the upper end of the pressing plate 27 can enable the bottom of the pressing plate 27 to contact the waste batteries, so that the waste batteries can have certain downward acting force to ensure the stability of the waste batteries during cutting when contacting the circular saw blade 19, and the waste batteries are not completely limited to be cut while being conveyed. At the time of cutting, a support plate 28 is provided at the bottom of the conveyor belt 15 on the upper side, and the support plate 28 can provide a rigid support for cutting the waste battery. And the support plate 28 is U-shaped to avoid the lower conveyor 15 and the guide hopper 21. The waste batteries are partially cut by the circular saw blade 19, so that the waste batteries form a drainage port. The cut-off portion of the waste battery falls down into the material guide hopper 21 and slides from the material guide hopper 21 into the feed port 6 to enter the reversing furnace 3. The waste batteries on the conveyor belt 15 are also poured into the turnover furnace 3 through the waste batteries with the cut-off vents under the action of the conveyor belt 15.

Meanwhile, nitrogen entering the turnover furnace 3 from the air inlet enters the top cover 17 at the top end from the hopper 12 and the feed inlet 6, so that the top cover 17 is full of nitrogen, and the nitrogen in the top cover 17 can ensure no oxygen or oxygen deficiency in the cutting process and hardly generates sparks.

Then the material valve 9 of the hopper 12 is closed, the motor 4 of the turning furnace is started, so that the waste batteries are fully contacted and mixed with the processing auxiliary materials 32, and the processing auxiliary materials 32 and the waste batteries are rubbed with each other. The sand grains and the iron grains accelerate the drying of the waste batteries, and the solidified electrolyte and active substances on the electrode plates are scraped into powder. And finally, opening a material valve 9 of the discharge pipe 8 to pour the waste batteries and the processing auxiliary materials 32 out of the discharge hole 10, and then separating the waste batteries, the powdered electrolyte solid and the powdered electrode plate active substances by using a screen. This is faster than the use of lye to discharge and then to dry, and also will not be consumed by lye partly available components.

Wherein, the processing auxiliary material 32 can also use a mixture of sand grains and graphite grains. The graphite particles have the same effect as the iron particles, and the resistance of the graphite is higher, so that the mixed discharge process of the waste battery is more stable. Since the hardness of graphite is not as high as that of iron grains, the processing aid 32 according to the preferred embodiment of the present embodiment uses sand grains and iron grains.

While the present invention has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
