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 multistage lead paste precipitation and separation process for a waste storage battery. The multistage lead paste precipitation and separation process comprises the process flows of waste lead-acid storage battery crushing, lead paste separation lead paste precipitation, second-stage precipitation and the like. Through the arrangement of a two-stage sedimentation tank, alead paste solution with low lead paste content in a first-stage sedimentation cylinder is introduced into the second-stage sedimentation tank; the lead paste solution in the second-stage sedimentation tank is aerated through an an aeration pipe group, so that the contact surface of a flocculating agent and the lead paste solution is further improved, and the flocculating agent and the lead pastesolution are mixed and reacted for a long time to obtain secondarily separated lead paste, that is to say, piston rods are driven through air cylinders to drive a support plate to move upwards, and the support plate moves a bottom plate out of the second-stage sedimentation tank, so as to take out the lead paste in the second-stage sedimentation tank. The lead paste in the waste lead-acid storagebattery is precipitated and separated out more thoroughly through twice precipitation, and the purification effect of the waste lead-acid storage 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...
