Abstract

The invention relates to a method for classification, crushing and recycling of waste batteries. First, the recovered waste batteries are soaked and de-charged, and then put into the crusher. The battery first passes through the equipment and comes to the A pipeline, and then under the action of gravity, it comes to the No. 1 cutter under the A pipeline for primary crushing. Remove the zinc cylinder from the surface of the battery. Then it enters the B pipeline, and the battery that removes the zinc cylinder is subjected to gravity, and enters the No. 2 cutter under the B pipeline. The No. 2 cutter performs secondary crushing to remove the black matter outside the battery. The broken battery is sent to the C pipeline and discharged to the receiving device. Through the method of graded crushing and recycling of waste batteries, waste batteries can be broken step by step; coarse zinc flakes and carbon rods can be recovered separately; and the value of waste dry battery recycling can be maximized.

Description

A method for classification, crushing and recycling of waste batteries

technical field

The invention relates to a method for classification, crushing and recycling of waste batteries, which belongs to the technical fields of waste battery treatment and environmental protection.

Background technique

With the continuous development of electronic products, the problem of battery disposal is becoming more and more serious. At present, the internationally accepted method is to solidify and bury deeply and store them in mine wells, but this method not only costs too much, but also causes waste of resources. There is another method, which is recycling. However, it is easy to recycle batteries, but it is difficult to crush them with high efficiency. As far as my country's current recycling technology is concerned, ordinary crushing methods have low work efficiency, incomplete and uneven crushing, Does not have specificity and other shortcomings.

The advantage of the present invention is that the waste battery graded crushing recovery method can realize the step-by-step crushing of the dry battery zinc cylinder and the black mixed substance inside the dry battery, and has high crushing efficiency and strong crushing specificity.

Contents of the invention

The purpose of the present invention is to provide a method for classification, crushing and recycling of waste batteries.

The present invention adopts the method of two kinds of crushing modes graded crushing, as shown in Figure 1. Firstly, the recovered waste batteries are soaked and deionized, and then put into the waste battery classification crushing recovery device, as shown in Figure 2. The two crushing methods use different knives respectively, as shown in Figure 3, the two knives have different functions, the No. It reaches more than 95%. The No. 2 rotary cutter (4) located below is used to destroy the black substance outside the carbon rod of the battery, and to keep the battery core almost intact. The battery first goes through the equipment to the A pipeline, and then it comes to the No. 1 rotary cutter (2) under the A pipeline under the action of gravity. After the primary crushing, the battery is removed from the zinc cylinder on the surface and comes to the B pipeline. The battery that has been removed from the zinc cylinder is subjected to gravity and comes to the No. 2 rotary cutter (4) below the A pipeline. The No. 2 rotary cutter (4) further crushes it. Drain the C line into the receiving tool.

Through the method of graded crushing and recycling of waste batteries, waste batteries can be crushed step by step; coarse zinc flakes and carbon rods can be recovered separately; and the value of waste dry battery recycling can be maximized.

detailed description

The specific experimental case is shown in Figure 2, including the following steps:

1. Turn on the device, put the waste dry batteries that need to be processed into the crusher after soaking and de-charging, and the dry batteries will fall freely from the A pipeline (1) to the top of the No. 1 rotary cutter (2) under the action of gravity. The rotary cutter (2) performs primary crushing on the dry battery, removes the zinc cylinder on the surface of the dry battery, and the zinc cylinder is received by the corresponding receiving tool, and the primary crushing is completed. The No. 1 rotary cutter (2) is characterized in that the teeth of the rotary cutter are distributed on the circumferential surface, and it is a multi-edged rotary cutter. There is a circular hole in the middle of the cutter, which can break the zinc cylinder of the dry battery without destroying the internal structure of the battery. Realize single crushing.

2. Then, the broken dry battery enters the B pipeline (3), and the zinc cylinder is discharged from the broken debris outlet on the B pipeline (3). When the dry battery slides down to the No. 2 rotary cutter (4), the separated black matter. The secondary crushing is completed. The No. 2 rotary cutter (4) is characterized in that the teeth of the rotary cutter are distributed on the circumferential surface, and it is a multi-edged rotary cutter. There is a circular hole channel in the middle of the cutter, which can break the black mixed substance inside the dry battery without destroying the carbon rod. , to achieve single crushing.

3. Finally, the thick carbon rod passes through the C pipe (5), is discharged from the C pipe (5), and is received by the corresponding receiving tool, and the separated black substance is discharged from the black mixed material outlet on the C pipe.
