I. Core Components and Technical Features of the Equipment The lead-acid battery recycling equipment from Jiangxi Mingxin adopts a modular design and is mainly composed of four parts: a crushing and sorting system, a heavy metal separation device, a plastic purification unit, and a wastewater treatment module. Its core technologies are reflected in the following three aspects: 1. Physical crushing and hydraulic sorting technology enable accurate separation of shells, lead paste, and separators, with a sorting purity of over 98%; 2. The patented electrolyte neutralization system achieves sulfuric acid recovery and meets discharge standards for neutralized wastewater through three-stage chemical treatment; 3. The intelligent control system is equipped with a PLC touchscreen operation interface, allowing real-time monitoring of equipment operation status and processing efficiency. II. Key Nodes of the Process Flow The equipment processing flow follows a closed-loop model of "crushing - sorting - refining": 1. The whole battery is transported by a conveyor belt into a rotary crusher, where it is safely crushed under the protection of inert gas; 2. The crushed materials are separated into three categories—plastic fragments, lead alloy grids, and lead paste—by a gravity sorting machine; 3. The lead paste enters the melting system to extract recycled lead (with a recovery rate of 96%), while polypropylene plastics are cleaned and granulated for reuse. III. Actual Application Data and Benefit Analysis According to the measured data from a recycling base in Jiangxi (2023): - Daily processing capacity of a single equipment: 10-12 tons of waste batteries - Power consumption per ton of material: 85kWh - Output ratio of recycled materials: lead ingots 82%, plastic 13%, sodium sulfate 5% Compared with traditional incineration processes, this equipment reduces heavy metal pollution emissions by 90% and saves 380 yuan per ton of processing cost. IV. Suggestions for Equipment Maintenance and Upgrade It is recommended that users pay attention to the following: 1. Clean the sediment in the hydraulic sorting tank monthly to prevent pipeline blockages 2. Regularly replace the neutralization packing in the acid gas absorption tower (recommended cycle: 1,500 hours) 3. For 2024 models, upgrade to nano-membrane filtration technology. Old equipment can contact the manufacturer to install this module Note: Operators must hold certifications and wear protective gear during processing, and the process must strictly comply with GB/T 37281-2018 standards. Detailed technical parameters of the equipment can be consulted on the Jiangxi Mingxin official website, where the Q/JMX 002-2022 enterprise standard is archived.
