Embodiment 1

[0037] Utilize waste lead-acid batteries to recover lead raw material system, mainly include crushing device, sorting device, desulfurization treatment device, smelting device and crude lead copper removal device, wherein crushing device includes crushing box 21, is installed in the crushing box 21 and is used for scrap lead Acid battery for crushing the rollers and a drive motor for driving the rollers; the bottom of the crushing box 21 is provided with a material output port 22 . The lead raw material sorting device includes a sorting box 1, and the upper part of the sorting box 1 is provided with a feeding port, and the feeding port communicates with the material output port 22 of the crushing device. There is a material distributing platform 2 below the feed inlet, the material distributing platform 2 is V-shaped, and the material distributing platform 2 is slidably connected to the inner wall of the sorting box 1, specifically: the front and rear inner walls of the sorting...

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is that the bottom of the crushing box 21 is provided with an intermittent feeding unit, which is used to intermittently feed the crushed materials into the lead raw material sorting device to reduce the accumulation of materials. probability. The intermittent feeding unit includes a cylinder 23 , the top of which is welded to the bottom of the crushing box 21 , and the bottom of the cylinder 23 is welded or abuts against the top surface of the sorting box 1 . The diameter of the barrel body 23 is larger than the bottom port of the material output port 22 of the crushing box 21 . A fixed plate 31 arranged horizontally is welded in the cylinder body 23, the left side of the fixed plate 31 is located below the material output port 22, and the right side of the fixed plate 31 is provided with a blanking port 30, which is located at the lead raw material point. The top of the feed port of the selection device is oppos...

Abstract

The invention relates to the technical field of waste battery recycling, and discloses a system for recycling lead raw materials by utilizing waste lead-acid batteries. The system comprises a lead rawmaterial sorting device, and the lead raw material sorting device comprises a sorting box, a material dividing platform, a first screen, ejector rods and a collecting tank; rotary drums are rotatablyconnected to the two sides of the collecting tank, and cylindrical cams are arranged at the tops of the rotary drums and matched with the ejector rods; first rotating shafts are rotationally connected to the two sides of the top of the sorting box, and one first rotating shaft is connected with a first motor; a transmission belt is connected between the two first rotating shafts; the two first rotating shafts penetrate into the sorting box and are provided with first gears, and outer gear rings are fixed to the rotary drums; and a plurality of layered centrifugation units for performing layered centrifugation on the materials are arranged in each rotary drum. According to the system, the probability that materials are accumulated can be reduced, the materials are in a dispersed state in the sorting process, and therefore lead raw materials in the materials can be separated out more easily, subsequent recycling treatment is facilitated, and the separation effect of the lead raw materials is improved.

Description

technical field [0001] The invention belongs to the technical field of waste battery recycling. Background technique [0002] Waste lead-acid batteries are lead-containing waste and are hazardous waste. Improper disposal of them will cause serious pollution of ambient air, soil, surface and groundwater resources, and then threaten human health through the food chain. Therefore need to reclaim the lead raw material in the waste lead-acid battery. [0003] The existing system for recycling lead raw materials of waste lead-acid batteries mainly includes crushing device, sorting device, desulfurization treatment device, smelting device and crude lead copper removal device. The crushing device crushes the waste lead-acid battery and sends it to sorting Sorting in the device to separate the lead raw materials, and then send the collected lead raw materials to the desulfurization treatment device for desulfurization treatment to obtain desulfurized lead paste; put the desulfurized...
