Problems solved by technology

However, there are still a large amount of lead powder (lead mud) in lead-acid batteries, as well as recyclable plastic products. It is a waste of resources that these materials are not classified and recycled, and lead can also cause heavy metal poisoning, which is harmful to the human body. harm
[0003] However, the current recycling process is backward, and the mixed pulverization recycling method is generally used. The recovery rate is low and the cost is high. Many recyclable substances are not recycled and discharged, especially some harmful substances such as lead are often not recycled and only diluted and discharged. , not only waste resources, but also pollute the environment

Embodiment 1

[0033] Such as figure 1 Shown, a kind of waste and old lead-acid battery crushing separation disposable energy-saving recovery process, comprises the following steps:

[0034] (1) Feeding

[0035] The waste lead-acid batteries in the raw material pit are grabbed by a six-petal hydraulic grab crane and sent to the silo above the feeder, and the vibrating feeder below the silo (the feeding speed is determined by changing the frequency of the motor to ensure uniform feeding) Feeding) The battery is transported to the belt conveyor, and an electromagnetic separator and a metal detector are installed above the conveyor belt to remove the magnetic metal mixed in the battery transportation process, so as to ensure the normal operation of the crusher and extend the life of the hammer. service life;

[0036] (2) Broken

[0037] The belt conveyor transports the waste lead-acid batteries to the crusher for crushing. There are four groups of 20 hammers in the crusher to beat and grind ...

Embodiment 2

[0060] A kind of waste lead-acid storage battery fragmentation separation disposable energy-saving recycling process, comprises the following steps:

[0061] (1) Feeding

[0062] The waste lead-acid batteries in the raw material pit are grabbed by a six-petal hydraulic grab crane and sent to the silo above the feeder, and the vibrating feeder below the silo (the feeding speed is determined by changing the frequency of the motor to ensure uniform feeding) Feeding) The battery is transported to the belt conveyor, and an electromagnetic separator and a metal detector are installed above the conveyor belt to remove the magnetic metal mixed in the battery transportation process, so as to ensure the normal operation of the crusher and extend the life of the hammer. service life;

[0063] (2) Broken

[0064] The belt conveyor transports the waste lead-acid batteries to the crusher for crushing. There are four groups of 20 hammers in the crusher to beat and grind the batteries. : 8...

Abstract

A waste lead-acid storage battery crushing-and-separation one-step energy-saving recycling process. According to work principle of a system in the process, an impact hammer crusher crushes a waste storage battery, and the crushed material is cleaned and separated through a vibration sieve to obtain lead plaster, and according to the physical characters of the crushed materials of the storage battery, wherein the specific gravities of the materials are different, the materials are separated through water buoyant force and compressed air, and finally, the materials are separately conveyed into different stores for storage through a spiral conveyor.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery recycling, in particular to a process for crushing and separating waste lead-acid batteries for one-time energy-saving recycling. Background technique [0002] At present, due to the unsatisfactory urban traffic conditions, more and more citizens buy electric bicycles. Generally, electric bicycles use a set of 3 or 4 lead-acid batteries, and their weight is about 12 to 16 kilograms. Lead-acid batteries are mainly composed of lead, sulfuric acid and some other metals and plastics. The average service life of this type of battery is 1 year, so a large number of lead-acid batteries are scrapped every year, which is worrying, and the disorderly management of lead-acid batteries has become a serious social problem. Vendors bought back used lead-acid batteries, dismantled them by hand, poured out the waste acid on the spot, and sold the disassembled lead plates of the batteries. However, the...
