The outer ring of the auxiliary plate 1201 is fixedly connected to the fixed seat 1205.

[0022] See also Figure 3 and Figure 4A guide rod 1206 is vertically penetrated and slidably installed on the surface of the fixed seat 1205. By setting the fixed seat 1205 and the guide rod 1206, the displacement of the displacement plate 1204 can be guided to ensure the movement stability of the displacement plate 1204. The bottom of the guide rod 1206 is fixedly connected with the displacement plate 1204. By setting the displacement plate 1204, the fixed installation requirements of the vibration motor 1203 and the upper pressure head 13 can be met.

[0023] See also Figure 3 and Figure 4 A spring 1202 is sleeved between the fixed seat 1205 and the displacement plate 1204 and on the outer side of the guide rod 1206. The two ends of the spring 1202 are fixedly connected to the fixed seat 1205 and the displacement plate 1204 respectively. By setting the spring 1202, an elastic supporting force can be provided for the displacement plate 1204 to prevent the displacement plate 1204 from being displaced randomly without external force. Vibration motors 1203 are bolted on both sides of the top of the displacement plate 1204. By setting the vibration motor 1203, a vibration group can be formed in the installed state, so that the displacement plate 1204 can be continuously vibrated and displaced up and down;

[0024] See also Figure 3 and Figure 4 The anti-blocking air bleed mechanism 15 includes a hollow tube 1503, and an auxiliary frame 1504 is fixedly sleeved on the bottom of the surface of the hollow tube 1503.

By providing the conical bucket 1501, the falling material can be guided to achieve the purpose of shielding and protecting the hollow tube 1503 and prevent the material from entering the hollow tube 1503.

[0026] See also Figure 3 and Figure 4 The top of the surface of the processing cylinder 8 is fixedly connected with a mounting frame 10. By setting the mounting frame 10, it can be fixedly connected with the processing cylinder 8, thereby meeting the fixed installation requirements of the hydraulic cylinder 11. The surface of the hydraulic cylinder 11 is fixedly connected with the connection of the mounting frame 10;

[0027] See also Figure 3 and Figure 4A discharge plate 16 is bolted to the center of the bottom of the processing cylinder 8. By setting the discharge plate 16, the heat in the processing cylinder 8 can be prevented from escaping at will in the installed state. The upper pressure head 13 is adapted to the lower bearing seat 14. By setting the upper pressure head 13 and the lower bearing seat 14, the solidified material on the lower bearing seat 14 can be crushed by extrusion when the upper pressure head 13 moves downward.

[0028] The bottom of the hollow tube 1503 is connected to an external gas pump through a pipeline, and the gas transmitted by the gas pump is the waste heat after the boiler is used in the lead-acid battery production process, thereby achieving the purpose of energy saving and better meeting actual use needs.

[0029] When in use, all components are in the initial state. The lead sludge produced by the production of lead-acid batteries is passed into the sedimentation tank 1 for sedimentation, and then the lead sludge is drawn out by the filtering and extracting equipment 2 after being filtered, placed in the spray cleaning tower 3 for cleaning, and then steam-cured by the steam curing equipment 4 to form a solid material containing moisture inside. The solid material is put into the processing cylinder 8 through the injection pipe 9, and the waste heat of the boiler in the production process of lead-acid batteries is introduced through the hollow pipe 1503. The hot gas evenly enters the processing cylinder 8 through multiple jet holes 1502, passes through the discharge hole 17 to dry the solid material on the lower bearing seat 14, and the gas is discharged from the injection pipe 9 along with the dried moisture. After the drying process is completed, the discharge plate 16 is disassembled. The processing cylinder 8 is then controlled to extend the hydraulic cylinder 11 and the vibration motor 1203, wherein the extension of the hydraulic cylinder 11 causes the displacement plate 1204 and the upper pressure head 13 to move downward synchronously, and the downward movement of the upper pressure head 13 plays a role of extrusion type crushing, while the operation of the vibration motor 1203 causes the displacement plate 1204 and the upper pressure head 13 to vibrate continuously, and the guide rod 1206 repeatedly moves up and down, and the spring 1202 is compressed or stretched, and then the upper pressure head 13 performs vibration type crushing on the solid material to achieve efficient crushing processing, and the qualified material falls through the discharge hole 17, and the discharge hole 17 plays a role of pre-screening, and then after fine screening by the material screening equipment 6, the horizontal mixing equipment 7 performs mixing processing.

[0030] In summary: the lead mud recycling system in the lead-acid battery production process solves the problem that the basic recycling system cannot combine the drying, crushing and pre-screening processes well, affecting the production efficiency, and each process is set up separately, which increases the site occupation area and also increases the actual production cost, and there are certain restrictions.
