Heavy metal separation device for lead-acid battery recovery wastewater treatment

Abstract

The invention discloses a heavy metal separation device for lead-acid battery recovery wastewater treatment, which comprises a stirring box, a settling box and a material taking box; the bottom of thesettling box is obliquely arranged, and the bottom of the stirring box is fixedly connected with the top of the settling box through a connecting rod.The invention relates to the technical field of alead-acid battery recovery. According to the heavy metal separation device for lead-acid battery recovery wastewater treatment, generated heavy metal precipitates fall into the precipitation box andthen move into the material taking box, the positioning ring plate is driven by the pull rope to move, and after the positioning ring plate moves to the contact position of the precipitation box and the material taking box, the heavy metal precipitates enter the positioning ring plate; the heavy metal precipitate is driven to move through the annular iron wire net; due to the fact that the material taking box is annular, when the positioning annular plate moves to the position over the material taking cabinet, the annular iron wire net is located above the heavy metal precipitate, the heavy metal precipitate enters the material taking box under the action of gravity, the heavy metal precipitate is taken out through the material taking box, complete treatment is not needed in the material taking process, and the time is saved.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery recovery, in particular to a heavy metal detachment device for waste water treatment of lead-acid battery recovery. Background technique [0002] In addition to lithium batteries, commonly used rechargeable batteries, lead-acid batteries are also a very important battery system. The advantage of lead-acid batteries is that the electromotive force is relatively stable during discharge, but the disadvantage is that the specific energy (electric energy stored per unit weight) is small and it is highly corrosive to the environment. Lead-acid batteries have stable working voltage, wide range of operating temperature and operating current, can charge and discharge hundreds of cycles, good storage performance (especially suitable for dry charging storage), and low cost, so they are widely used. Lead-acid batteries refer to batteries whose electrodes are mainly made of lead and its oxides, and ...
