Graded crushing and recovering method for waste batteries

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...
