Continuous graphitization furnace and production system for lithium battery negative electrode material

Abstract

The invention relates to the technical field of lithium battery negative electrode production, in particular to a continuous graphitization furnace of a lithium battery negative electrode material and a production system.The continuous graphitization furnace of the lithium battery negative electrode material comprises a graphitization furnace body, a rotary supporting seat and a first pushing device, and the rotary supporting seat is used for being arranged on a working face; the graphitization furnace body is rotationally connected with the rotary supporting seat; the first pushing device is connected with the graphitization furnace and is used for driving the graphitization furnace to rotate relative to the rotary supporting seat. It can be seen that the pushing device drives the graphitization furnace body to rotate around the rotary supporting seat, so that the graphitization furnace body is in an inclined state, and the crucible placed in the graphitization furnace body is convenient to slowly move from the inlet end of the graphitization furnace to the outlet end under the action of gravity or small thrust, so that the graphitization furnace can be used for graphitization. The mechanical degree is high, the working efficiency is improved, in addition, the graphitization furnace can slowly rotate by 360 degrees, and excessive abrasion between the graphite crucible and the heating electrode is avoided.

Description

Technical field [0001] This application relates to the technical field of lithium battery anode production, and in particular to a continuous graphitization furnace and production system for lithium battery anode materials. Background technique [0002] The main configurations of a traditional graphitization furnace include furnace walls, furnace core (composed of furnace products and resistance materials), coke powder preheating material outside the furnace core, and high-current conductors (composed of aluminum and copper bars). Among them, the high-current conductor is used to connect the transformer and the graphitization furnace into an energized circuit. Under the action of the current, it generates heat through its own resistance, and finally achieves high-temperature graphitization. The conventional graphitization production process includes: (1) furnace loading: loading the crucible carrying materials to be graphitized, such as lithium battery negative electrodes, i...
