Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] see Figure 1-11 , in the embodiment of the present invention, a kind of waste storage battery multistage lead paste sedimentation sorting process is characterized in that, the specific steps of this sorting process are:

[0045] Step 1: Crushing of waste lead-acid batteries: crush the waste lead-acid battery materials that need to be processed, so that the waste batteries are broken into broken materials;

[0046] Step 2: Precipitation of lead paste: ...

Abstract

The invention discloses a multi-stage lead paste precipitation and sorting process for waste batteries, including the process flow of crushing of waste lead-acid batteries, lead paste precipitation, lead paste precipitation, and secondary precipitation. By setting a secondary settling box, the first-stage The lead plaster solution containing a low amount of lead paste in the sedimentation tank is introduced into the secondary settling tank, and the lead plaster solution in the secondary settling tank is aerated through the aeration tube group to further increase the contact surface between the flocculant and the lead plaster solution. The flocculant and the lead plaster solution are mixed and reacted for a long time to obtain the secondary precipitated lead paste, that is, the cylinder drives the piston rod to drive the support plate to move upward, so that the support plate moves the bottom plate out of the secondary settling tank, and then takes it out of the secondary settling tank lead paste, that is, through two precipitations, the lead paste in the waste lead-acid battery is precipitated more thoroughly, and the purification effect of the waste lead-acid battery is better.

Description

technical field [0001] The invention belongs to the technical field of waste battery treatment, in particular to a multi-stage lead paste precipitation and separation process for waste batteries. Background technique [0002] As the most widely used chemical power source in the world, lead-acid battery has the advantages of stable voltage, safety and reliability, low price, wide application range and abundant raw materials. According to incomplete statistics, my country's lead-acid battery manufacturers have reached about 1,500, and the production volume has increased substantially at a rate of about 20% per year. In recent years, due to the development of the automobile industry, the proportion of lead used in lead-acid batteries to lead consumption is also increasing, from 27% in the 1960s to 80-85% at present; With the rapid development of China and the promotion of clean production and environmental protection, the consumption of lead-acid batteries is also developing r...
