Abstract

The invention provides a combined method and device for charged crushing of waste lithium-ion power batteries, which is to put waste lithium-ion power batteries into the inner chamber of the first crusher with an open bottom outlet through a feeding platform, so that the batteries are sheared and shredded for pretreatment into coarse Then the battery coarse material is quickly dropped into the corrosion-resistant water tank docked with the discharge port of the first crusher, so that the battery coarse material will fail under immersion in water; the battery coarse material falling in the water tank is soaked in the The conveyor belt in the water tank is sent to the belt dryer, and the conveyor belt set in the drying chamber of the belt conveyor is dried at the same time as it is transferred, and then sent to the second crusher for further crushing into fine materials. The invention adopts coarse crushing pretreatment and water immersion to protect the safety of lithium battery crushing, eliminates potential safety hazards in the processing process, and avoids the disadvantage of being unable to sort due to overhumidity of materials through subsequent drying, which is safe and reliable , high degree of automation, no waste water outflow, effectively avoiding environmental pollution.

Description

technical field [0001] The invention relates to the technical field of waste battery recycling, in particular to a method and a device for combined charging and crushing of waste lithium ion power batteries. Background technique [0002] With the continuous growth of the number of new energy vehicles, it not only brings a huge demand for power lithium batteries, but also an industry opportunity for lithium battery recycling and cascade utilization. The development of lithium battery recycling and cascade utilization will avoid waste of resources and pollution, and will also Generate considerable economic benefits and investment opportunities. How to deal with these waste lithium-ion batteries has always been a big problem to be solved in our country, which is not only related to environmental protection, but also related to the recycling of natural resources. However, in order to recycle the waste lithium-ion battery, the waste lithium-ion battery must be crushed first. ...
