Abstract

The invention discloses a raw material impurity removing and grouting device applied to lithium battery manufacturing. The raw material impurity removing and grouting device comprises a dry powder screening box, a driving motor, a wet powder screening box and a material mixing rotary drum, the top of the dry powder screening box is in threaded connection with a box body cover plate, perspective glass is connected to the outer side of the dry powder screening box in a penetrating mode, the driving motor is installed on the outer side of the dry powder screening box, a discharging pipeline is fixedly welded under the dry powder screening box, the outer side of the wet powder screening box is in threaded connection with a grouting faucet, and a feeding pipeline is fixedly installed in the dry powder screening box. The raw material impurity removing and grouting device applied to lithium battery manufacturing is provided with a two-way lead screw and material mixing panels, the two-way lead screw is used for driving the material mixing panels on the left side and the right side to rotate, the two-way lead screw is used for driving the material mixing panels to obliquely rotate, the material mixing panels are used for grinding the outer sides of materials, and different types of material bodies in the materials can be conveniently stirred and screened.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a grouting device for removing impurities in raw materials used in lithium battery manufacturing. Background technique [0002] In the production process of lithium battery manufacturing, the materials of different proportions of lithium manganese oxide, lithium cobalt oxide and lithium nickel oxide are mainly mixed and stirred. Lithium alloy metal oxide is used as the positive electrode material, graphite is used as the negative electrode material, and batteries using non-aqueous electrolytes , The raw material impurity removal grouting device used in the manufacture of lithium batteries is to screen the materials that do not meet the size of the raw materials and the impurities inside the materials, so as to reduce the content of impurities inside the raw materials. [0003] The first step in the production of lithium batteries is the preparation of electr...
