A kind of lead slime recycling method

Abstract

The invention discloses a lead slime recycling and utilizing method which comprises the following steps: (1) recycling the lead slime, namely, feeding the lead slime subjected to separation by using a filter press into a bucket; (2) drying, namely, putting the bucket with the lead slime into a curing chamber and drying so as to reduce the water content of the lead slime inside the bucket to be less than 3%; (3) polishing and screening, namely, polishing the cured lead slime by using a grinding machine, and screening by using a 80-mesh sieve; (4) recycling, namely, conveying the ground lead powder into a mixer. The lead slime recycling and utilizing method is simple in process, and the curing chamber for machining batteries is adopted for curing, so that waste recycling and utilization can be achieved without purchasing extra new equipment, the investment is reduced, the economic benefits of companies are increased, the energy is saved, the emission is reduced, and the consumption is reduced.

Description

technical field [0001] The invention belongs to the field of accumulator manufacturing, and in particular relates to a method for recycling lead slime. The equipment used for producing accumulators is used to recycle the lead slime. Background technique [0002] At present, lead-acid batteries are becoming more and more popular among citizens as a means of transportation. In the process of processing lead-acid batteries, especially in the process of acid coating, a large amount of lead sludge and waste acid will be produced. The lead sludge filtered by the machine is generally treated according to the national standard and not recycled, but the lead sludge contains a large amount of lead powder. If the lead powder is discarded, it will not only cause lead poisoning, but also waste resources. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a method for recycling the lead slime, in which the solidi...

Problems solved by technology

[0002] At present, lead-acid batteries are more and more popular among citizens as a means of transportation. In the process of processing lead-acid batteries, especially in the process of coating and leaching acid, a large amount of lead sludge and waste acid will be produced. The lead slime filtered by the machine is generally processed according to the national standards and is no longer recycled. However, the lead slime contains a large amount of lead powder. If these lead powders are discarded, they will not only cause lead poisoning, but also waste resources.
