A method of pre-treatment and components separation of waste lead-acid accumulator

The invention relates to a method for the pretreatment and the components separation of a waste lead-acid battery with separated components, the method is used for processing the waste lead-acid battery during the recycling process of lead, solid and liquid are separated preliminarily by the overturning of a hydraulic six-petal grab crane, solid materials are treated with electromagnetic iron removing, magnetic metal detection, crushing and screen filtering, a prepared lead paste is connected to a lead paste stirring storage tank by using a scraping machine, then a pump is used for sending the lead paste to a filter press to obtain a lead-containing filter cake and an electrolyte, the filter cake returns for lead smelting; one part of the electrolyte returns to a system, one part is sent for preparing a sulfuric acid, a water power separator is connected before a sieve plate of a vibration sieve to separate the lighter solid, the sealing parts of a crushing machine head, a scraping machine head, the lead paste stirring storage tank and the filter press, etc. are connected to an air purifier by using a pipeline, then the electrolyte is sent to a chimney by a fan; the method has the advantages of thorough separation, low energy consumption, good environment and less investment.
