Waste battery sorting method

Abstract

The invention discloses a waste battery sorting method which comprises the following steps: (1) primary selection of waste batteries: conveying metal garbage subjected to magnetic separation and a battery mixture into a battery sorting trough through a first conveying belt, wherein metal substances with sizes less than sizes of batteries fall into a second conveying belt from an outlet of the battery sorting trough; (2) detection of the batteries: judging the metal garbage and the barriers in the battery mixture on the second conveying belt according to the fact that the batteries have the electricity output characteristics; and (3) grabbing of the waste batteries: grabbing the batteries, confirmed in the step (2), through a battery grabbing manipulator, and putting the batteries into a waste battery collection box. According to the waste battery sorting method, workers can be replaced for sorting the waste batteries in household garbage subjected to the magnetic separation, so that pollution to the environment due to the waste batteries is prevented; and the waste battery sorting method is high in automation degree, time-saving and labor-saving.

Description

technical field [0001] The invention relates to a method for sorting waste batteries. Background technique [0002] Around our lives, many waste items are thrown into trash bins without classification every day, including recyclable garbage-batteries, which are incinerated, buried, or even discarded randomly, which will cause environmental pollution, water and soil pollution in the long run. Inhale harmful metals and cause harm to human body. Due to the irrational use of resources, it will also cause waste of resources. In the case of decreasing non-renewable resources, rational use of resources can suspend the use of resources. The amount of domestic waste in cities and rural areas is increasing, the composition is becoming more and more complex, and there are more and more types. It is becoming more and more difficult to classify recyclable and non-recyclable garbage. The traditional system and methods are often unable to meet the requirements of economic development and...

Problems solved by technology

Although this approach can bring some convenience for the public to participate in garbage sorting and recycling, it will make the public feel troublesome during the implementation process, and there will be littering, which leads to the limited coverage of this service and poor practicability

If things go on like this, it is difficult for these garbage sorting and recycling methods to continue to operate. At present, no similar solutions have been found for this type of problem.

[0003] And because the main components in the battery are iron and nickel, familiar with magnetic substances, it is impossible to separate the battery from other wastes by using a magnetic separator, but because the heavy metals mercury, cadmium, zinc, etc. ℃, cadmium is 765 ℃, zinc is 907 ℃), at high temperature, it is easy to gasify and volatilize, and some heavy metals react in the incineration furnace to form their chlorides, oxides or sulfides, which are easier to gasify and volatilize than the original metal elements

These heavy metals and their compounds will enter the atmosphere through the chimney, causing soil pollution and air pollution, and some metals will enter the furnace ash, which will further increase the difficulty of treatment.
