Waste dry battery pretreatment recovery process and recovery treatment device

Abstract

The invention discloses a waste dry battery pretreatment and recovery process and a recovery treatment device, and belongs to the field of resource recycling. According to the present invention, through a waste battery recovery process, the electrolyte and a metal shell are firstly separated from each other, then the electrolyte flows out, and after a waste battery is disassembled, the metal shellis recycled, and the electrolyte flushes out and is uniformly mixed, the two above steps can be carried out at the same time, and the waste battery recycling step has coherence. Compared with the phenomenon in the prior art that part of electrolyte cannot be completely recycled, according to the present invention, the electrolyte can be fully flushed out and intensively mixed through a high-pressure water pipe, so that the metal recovery rate of the waste batteries is increased. Meanwhile, the device used in the process can dissipate heat generated instantaneously in the waste battery recovery process in time, so that the safety of waste battery pretreatment is improved.

Description

technical field [0001] The invention relates to the field of resource regeneration and utilization, more specifically, to a waste dry battery pretreatment recovery process and recovery treatment device. Background technique [0002] After the lead-acid battery is scrapped, it needs to be disassembled to separate the shell from the plate before it can be smelted. The existing dismantling method is to use a machete to separate the plastic cover on the upper part of the shell from the shell, and then use a manual electric pick to re-smelt it. The single component of the nose welding is separated, and the pole plate is melted in the smelting furnace to produce reduced lead; the outer shell is crushed by a plastic shredder to produce plastic particles. However, in the existing dismantling method, each battery needs to be cut several times to separate the cover shell, which is difficult to disassemble, and the residual electrolyte of the battery after cutting will cause the acid s...

Problems solved by technology

[0004] Although the above-mentioned invention patents refine the battery dismantling process, the dismantling process is not direct and coherent enough, and it is easy to cause the electrolyte solution in the dry battery to not be completely collected after dismantling, which increases the difficulty of later purification treatment, and the above-mentioned invention During the dismantling process, the waste battery will generate heat under the impact of dismantling. If the heat is not discharged in time, the battery may explode, causing huge losses to the overall equipment and even threatening the safety of the staff.
