Description

High-efficient washing drying equipment of positive electrode material Technical Field The utility model belongs to the technical field of battery anode material processing, and particularly relates to efficient water washing and drying equipment for an anode material. Background The moisture in the battery can affect the performance of the battery, such as causing deterioration of electrolyte, generation of harmful gas by reaction with the electrolyte, causing problems of increased internal pressure, deformation, high internal resistance, high self discharge, low capacity, poor circulation, and even leakage of liquid in the battery, so that the moisture content needs to be controlled at an extremely low level by drying, the moisture content is generally required to be between (100 and 300) x 10- 6 ppm, and the heated air is used as a drying medium to transfer heat to the material by convection so as to evaporate the moisture in the material. This method is suitable for drying most battery materials, but it still has the following drawbacks in practical use: In the drying process of the positive electrode material, the positive electrode material of the battery is directly dried by adopting drying equipment, and in the drying process, the positive electrode material on the fluidized bed flows, but in the flowing process, the pressures of different positions are different in hot air conveying, and the holes on the fluidized bed are easily blocked by the materials in the conveying process, so that the drying effect of the materials is affected; Secondly, the whole drying equipment of material discharge after the drying, after the material output after the drying, still need the concentrated material after the drying of extra collecting hopper, and in its operation, the material is blown out by the air current easily in output process, and it is inconvenient to collect.
