Problems solved by technology
[0004] The purpose of the present invention is to provide a sulfuric acid paste smelting method based on waste lead storage batteries, which mainly solves certain defects in the existing sulfuric acid paste smelting methods based on waste lead storage batteries. High temperature or harmful gases are generated during the smelting process. , is easily discharged to the outside of the smelting device and affects the air environment, and even affects the health of the staff. It does not play a good protective role, the sealing performance is relatively poor, and the high temperature waste heat after the smelting process is usually discharged to the outside, which does not have The problem of the function of energy saving and consumption reduction

The invention discloses a lead sulfate paste smelting method based on waste lead storage batteries. The lead sulfate paste smelting method based on the waste lead storage batteries comprises the following specific steps: step 1, collecting the waste lead storage batteries, and putting the plurality of groups of waste lead storage batteries into a crusher for cracking and crushing, and then extracting lead sulfate paste in the waste lead storage batteries through filter pressing and dehydration. According to the invention, high temperature or harmful gas in an oxidation box can be prevented from being discharged out of the device to influence the air environment, a good protection effect is achieved, good sealing performance is achieved, certain required temperature conditions can be provided for smelting of the reduction box by means of waste heat in the oxidation box, the energy consumption required for generating high-temperature heat in the reduction box is reduced, and a good energy-saving effect is achieved.
Description
technical field [0001] The invention belongs to the technical field of recycling waste lead storage batteries, in particular to a method for smelting lead sulfate paste based on waste lead storage batteries. Background technique [0002] After more than 100 years of development and improvement, lead-acid batteries have become a chemical power source widely used in the world. It is also the battery with the largest output and widest application in the world. It is an indispensable product in social production and operation activities and human beings. . With the progress of society, the demand for resources is also increasing, and the global mineral resources are depleting day by day, it is particularly important to improve the recycling of renewable resources, and to continuously improve the level of equipment and adopt the recycling technology of lead-acid batteries. is the key to development; [0003] The existing lead sulfate smelting method based on waste lead batterie...
