Abstract

The invention belongs to the technical field of waste lithium battery recycling equipment, and particularly relates to new energy automobile waste lithium battery wet recycling equipment which comprises a recycling barrel fixedly connected with an external connecting piece. A first liquid supply system used for assisting battery discharging and a second liquid supply system used for assisting stripping of active substances in a battery are communicated to the recycling barrel, and an ultrasonic module used for stripping the active substances in the battery is fixedly connected to the bottom of the inner wall of the recycling barrel; the outer wall, close to the middle, of the recycling barrel is provided with a discharging port communicated with the inner cavity, and the discharging port is rotationally connected with a sealing bin gate. Discharging and active substance stripping are conducted in the recycling barrel, related assemblies are matched with the first liquid supply system and the second liquid supply system, the operation steps are simplified, the recycling efficiency is improved, and the recycling efficiency is improved. And meanwhile, the problem that the punctured battery is easy to leak during transfer is solved.
