Abstract

The invention relates to an efficient powder discharging device for lithium ion battery pulp combining. The efficient powder discharging device comprises a metering bin, a discharging funnel and a discharging pipeline, all of which are sequentially arranged and combined from top to bottom. A vent valve and a metering bin feeding port are formed in the top end of the metering bin, the lower end of the metering bin is connected with the discharging funnel in a penetration manner, the lower end of the discharging funnel is connected with the discharging pipeline in a penetration manner, and a port in the lower end of the discharging pipeline is connected with a pulp combining kettle. After the above structure is adopted, compared with the prior art, according to the efficient powder discharging manner for lithium ion battery pulp combining and a discharging system of the efficient powder discharging manner, the structure is simple, metering is accurate, reliability is high, and continuous production can be achieved; and meanwhile, through the arrangement of an air hammer and a crossed concentric-square-shaped air blowing structure, the discharging efficiency and the discharging precision are effectively improved.

Description

technical field [0001] The invention relates to a production blanking device, in particular to a high-efficiency powder blanking device for lithium-ion battery slurry mixing. Background technique [0002] The active materials of lithium batteries must go through the process of batching, mixing with corresponding solvents, stirring and dispersing evenly, and making slurry before they can be used in the manufacture of lithium batteries. During the mixing process, the small particles in the active material of the powder are likely to cause dust pollution and pollute the working environment. A small amount of powder active material remains in the packaging bag after feeding, and it is easy to pollute the working environment. Represented by lithium iron phosphate cathode materials and carbon nanotube conductive agents, the situation of dust pollution is particularly serious. [0003] The State Intellectual Property Office of the People's Republic of China announced an invention...
