Crushing and sorting system for lead-acid storage battery

Abstract

The invention discloses a crushing and sorting system for a lead-acid storage battery, and belongs to the technical field of recovery of lead-acid storage batteries. The crushing and sorting system comprises a crushing and sieving unit, a lead plaster collection unit and a hydraulic sorting unit. The crushing and sieving unit is used for crushing and sieving a to-be-recovered lead-acid storage battery. The lead plaster collection unit is used for separating and collecting undersizes obtained through separation of the crushing and sieving unit. The hydraulic sorting unit is used for separatingand collecting the undersizes obtained through separation of the crushing and sieving unit. According to the crushing and sorting system, the lead-acid storage battery is crushed by a compound crusherinnovatively, the lead-acid storage battery is crushed only by one compound crusher, lead metals, heavy plastics and light plastics are separated simultaneously by a hydraulic back flushing flotationdevice, not only is the recovery rate of the lead-acid storage battery up to more than 98%, but also the whole crushing and sorting system is greatly simplified, and required support devices are reduced; and compared with the prior art, the crushing and sorting system has the advantages that the occupied area can be reduced by more than 60%, the power consumption can be reduced by more than 40%,and the operation cost is lowered when the investment of enterprise devices is reduced.

Description

technical field [0001] The invention belongs to the technical field of recovery of lead-acid batteries, in particular to a crushing and sorting system for lead-acid batteries. Background technique [0002] Lead-acid battery is the battery with the largest output and widest application among all kinds of batteries in the world. However, with the continuous increase of battery usage, a large number of waste batteries are produced, and waste batteries contain a large amount of lead metal and waste acid. , spent alkali and other electrolyte solutions. Recycling the used waste lead-acid batteries can not only prevent environmental pollution, but also reuse the recyclable parts to save resources. [0003] The Chinese invention patent with the notification number CN 103490115 B discloses a battery recovery and separation system, including: a crushing and screening unit for crushing and screening the battery to be recovered; a lead paste recovery unit for separating the battery fro...

AI Technical Summary

Problems solved by technology

[0004] However, the Chinese invention patent whose notification number is CN 103490115 B has the following disadvantages: (1) two or more crushers need to be used, and the power of the crushers is extremely high, which leads to complex techniques and control of the crushing process, requiring equipment installation. The space is large, the supporting equipment is increased, and the power consumption is high, which greatly increases the equipment investment and operation cost; (2) The hydraulic recoil device is a vertical cylindrical structure, and the mixing inlet is bent at the cylindrical barrel, which not only feeds The structure is complex, and due to the upward resistance of the water flow, it is necessary to equip a separate feeding mechanism to force the feeding; (3) The separation efficiency of the single-stage hydraulic recoil device is high, and it cannot be realized simultaneously for light plastics, heavy plastics and lead metals. For the sorting, it is necessary to configure the combination process of 3-stage hydraulic flotation device and flotation vibration, which further increases the process and control complexity of the whole system
