A method and device for dismantling lead-plastic separation of waste lead-acid batteries

Abstract

The invention discloses a method and a device for dismantling lead-plastic separation of waste lead-acid batteries. The separation method includes the following process steps: (1). Preparation for loading; (2). Remove the upper cover; the cover removal machine uses a reciprocating mechanism to cooperate with the stopper fixed on the support frame of the cover removal machine, and squeezes the waste lead Remove the upper shell of the acid battery, (3). Crushing the box; send the waste lead-acid battery box to the known battery pulverizer through the conveyor belt to pulverize it into pieces; (4). Buoyancy sorting; battery pulverization The machine puts the waste lead-acid battery box fragments into the separation pool of the separation mechanism. The separation pool is filled with separation liquid. The density of the separation liquid is between the density value of plastic and lead metal. Using the difference in buoyancy, the battery box The lead metal and plastics of scraps are automatically separated; (5). Sorting and recycling. The separation device includes five parts: feeding machinery, cap removal device, conveying machinery, battery crushing machinery and the main innovative separation mechanism.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a method and device for dismantling and separating lead and plastic from waste lead-acid batteries. Background technique [0002] Lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main component of the positive and negative electrodes is lead sulfate. [0003] Due to its stable quality, high reliability, and good safety performance, lead-acid batteries are widely used in transportation, electric power, communications, military, and aerospace. Therefore, it is very important to separate and recycle the waste of waste lead-acid batteries; it can not only reduce the pollution of lead-acid batt...

AI Technical Summary

Problems solved by technology

[0004] Lead-acid battery is a battery composed of lead and plastic. Although there are many designed methods and equipment at this stage, many methods and equipment have problems such as low efficiency, poor practicability, and difficult processing and manufacturing.

Chinese patent (CN201410076147.9) introduces a method for full-cycle recovery and treatment of waste lead-acid batteries. This method separates waste lead-acid batteries after sawing, and the product conversion rate and purity are higher than those obtained by previous separation methods; its disadvantages This method needs to add multiple devices to realize its function, the separation speed is not easy to control in actual operation, and the coordination of each device is poor

Chinese patent (CN200810117607.2) introduces an automatic sorting and splitting method for the recycling of waste lead-acid batteries. Separation efficiency is low

Chinese patent (CN 201210143964.2) introduces a separation and screening device for waste lead-acid batteries. This device can realize the separation and recovery of lead-acid batteries after crushing and has a high recovery rate. Sex is not high

It uses X-rays to detect waste lead-acid batteries, then cuts the lead-acid batteries, separates and recycles them after crushing. This process system is harmful to the human body and the environment, and the cost of implementation is high.
