Embodiment Construction

[0029] A method for reclaiming and utilizing lead acid-leached solid waste of battery plates, comprising the following steps:

[0030] (1) Prepare a recovery and utilization system for the treatment of lead-containing suspended acid produced during the production of battery plates.

[0031] (2) The plate smears are mass-produced separately, and the composition, quantity, and composition of the lead alloy in the lead-containing suspension acid solution are clearly recorded. The collection of lead-containing suspended acid produced during the process of separating the positive and negative plates should be handled separately and collected collectively. Because the additive components in the positive and negative plates are different, they cannot be used in confusion. In order to facilitate recycling and reduce reuse raw materials and costs, batch manufacturing of the same electrode should be carried out in the separation and brushing process of battery plates, that is, positive...

Abstract

The invention belongs to a recovering and utilizing method for a solid waste acid-leaching lead slime on a polar plate of a storage battery and a system. According to the method, an obtained lead-bearing suspension acid liquid is collected and lead powder in the lead-bearing suspension acid liquid is immediately separated from an acid leaching liquid through a pressure filtration method. The recovered lead powder is collected, dried, crushed and decontaminated and then is recycled according to the components and the amount of the lead powder. The system comprises a weighing control adder, a vacuum paste mixing machine, a plate coating machine and a crushing and decontaminating machine. The lead-bearing suspension acid liquid can be automatically separated and recycled immediately, so that the problems that the lead-bearing suspension acid liquid pollutes the environment, and is high in recovery cost and large in floor area can be effectively solved, and the system has the advantages of being reasonable in method, simple in structure, low in recovery cost, high in resource recovery utilization ratio and good in energy-saving and environment-friendly effects.

Description

[0001] technical field [0002] The invention belongs to a method and system for recovering and utilizing lead acid sludge from solid waste of storage battery pole plates. Background technique [0003] In the manufacturing process of the raw plate of the storage battery, the smear is to apply the lead paste on the cast grid through the plate coating machine. In order to ensure the product quality and prevent excessive water loss on the surface of the plate, the wet The surface of the plate is required to be acid-leached to form a lead sulfate layer to prevent the surface of the plate from cracking. However, after the plate is soaked and washed with acid, a large amount of lead-containing suspended acid will be produced. This large amount of lead-containing suspended acid needs to occupy a large number of sealed containers and sites for long-term precipitation. After a long period of precipitation, the precipitate formed The waste is lead acid sludge, which is hazardous s...
