Embodiment Construction

[0027] 1. battery sorting

[0028] Firstly, the batteries are screened by a screening machine, so that the waste batteries are classified according to the type and specification. The screening machine is equipped with spray water to wash these batteries and remove the solid particles contaminating the batteries. Then batteries of different specifications are led to the magnetic separator for magnetic separation to obtain acidic and alkaline zinc-manganese batteries. Other batteries are sorted and stored for later use.

[0029] 2. Mechanical crushing and separation of batteries

[0030] Use a battery cracker to break up the battery. When crushing, it should be noted that the shell of the battery should be relatively large pieces, and the substances should not be embedded in each other. A sieving device is used to separate bulk material from powder under the action of a stream of water. Bulk substances include iron sheets, zinc cylinders, sealing asphalt, plastic part...

Abstract

The invention provides a method for separating a shell, electrolyte, an electrode material, a collector and the like of a waste zinc-manganese battery by using a physical method, as well as a method for preparing a zinc-manganese soft magnetic ferrite material by taking the electrode material and electrolyte obtained through separation as main raw materials. According to the method, the particularity of the zinc-manganese battery manufactured in different periods is considered, byproducts of sodium salts and ammonia water are generated, and the heat energy of all organic matters contained in the waste battery and all the metal components are recovered. Due to proper control, pollutants are not released into the environment, a low-cost route is provided for resourcing of the waste zinc-manganese battery, and the method is a production technology which accords with the principle of circular economy.

Description

technical field [0001] The invention belongs to the field of solid waste recycling, in particular to a method for preparing zinc-manganese soft magnetic ferrite by using waste zinc-manganese batteries. Background technique [0002] Zinc-manganese dry battery is a kind of primary chemical power source, which has the characteristics of low price and good storage performance, and is widely used in low-power portable devices, such as clocks, remote controls, radios, cameras, etc. In recent years, secondary batteries such as lithium-ion batteries and nickel-metal hydride batteries have widely replaced zinc-manganese dry batteries in frequently-used larger-power portable devices because of their high energy density and power density and low cost of use. [0003] Nevertheless, zinc-manganese batteries still occupy a considerable share in the battery market, and a large number of waste batteries are produced every year. There are two types of zinc-manganese batteries, one uses ammo...
