Example Embodiment

[0030] As shown in the figure, the specific steps are as follows:

[0031] (1) Break the waste battery in the storage pit so that the waste electrolyte can flow to the storage pit by itself;

[0032] (2) Send the broken waste battery to the hopper of the vibrating feeder, and then convey it to the crusher by the conveyor belt. The magnetic metal and iron fragments in the waste are detected by the magnetic separation equipment installed on the conveyor belt It is screened and separated to protect the crusher after being crushed by the crusher to produce mixed crushed materials with the largest particle size not greater than 80MM, and the crushed materials directly enter the oscillating separator;

[0033] (3) After the pulverized material is separated by shaking, the slurry enters the sedimentation collection tank to concentrate the slurry into lead paste concentrated slurry; the large particulate matter left on the screen of the vibrating separator enters the hydrodynamic separato...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of lead smelting in the non-ferrous metal smelting industry, and in particular relates to a method for pretreatment and component separation of waste lead-acid batteries used in the separation of components of waste lead-acid batteries in the lead recycling process. Background technique [0002] The output of secondary lead metal in developed and moderately developed countries has exceeded the output of primary lead metal. The ratio of secondary lead output to total output is more than 70% in the United States, more than 78% in Europe, and 50% on average in the world, and only 25∽30% in my country. below the world average. my country's secondary lead technology is backward, and the recycling work is not perfect is a major factor causing this situation. At present, the more representative technologies for recycling lead from waste batteries are as follows: [0003] 1. The recycled lead smelter in BROOKLYN, A...
