Problems solved by technology

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, Disadvantages such as lack of specificity

Embodiment Construction

[0011] Specific experimental cases such as figure 2 , including the following steps:

[0012] 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.

[0013] 2. Then, the broken dry ba...

Abstract

The invention provides a graded crushing and recovering method for waste batteries. Recovered waste batteries are subjected to soaking and electricity removal and then are thrown into a crusher, the batteries firstly reach a pipeline A through equipment and then reach a first cutter below the pipeline A under the action of gravity, and primary crushing is carried out to remove zinc cylinders on the surfaces of the batteries; the batteries with the zinc cylinders removed enter a pipeline B and then enter a second cutter below the pipeline B under the action of gravity, and the second cutter conducts secondary crushing to remove black substances outside the batteries; and crushed batteries are conveyed to a pipeline C and discharged to a receiving device. By means of the graded crushing and recovering method for waste batteries, graded crushing of the waste batteries can be achieved, rough zinc sheets and carbon bars can be recovered separately, and the recycling value of waste dry batteries is maximized.

Description

technical field [0001] 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 [0002] 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. [0003] The advantage of the present invention is that the waste battery graded crushing r...
