Embodiment Construction

[0013] Such as figure 1 As shown, the high-efficiency feeding method and feeding system of the powder for lithium-ion battery slurry mixing include a metering bin, a feeding funnel, and a feeding pipeline, and the metering bin, feeding funnel, and feeding pipeline are poured from top to bottom in sequence Arrangement and combination; the top of the metering bin 3 is equipped with a vent valve 2 and a metering bin feed port 1, the lower end of the metering bin 3 is connected to the feeding funnel 5-1, and the lower end of the feeding funnel 5-1 is connected to the feeding funnel 5-1. The pipeline 6-1 is through-connected, and the lower end port of the feeding pipeline 6-1 is connected with the slurry mixing kettle 11. Wherein, what the present invention adopts is that the metering bin 3, the feeding funnel 5-1 and the feeding pipeline 6-1 are integrally combined for feeding. The metering bin 3, the feeding funnel 5-1 and the feeding pipeline 6-1 are sequentially connected from...

Abstract

The present invention involves a kind of high -efficiency device for lithium -ion battery bodies, including measuring warehouses, feeding funnels, and feeding pipes.; The measuring warehouse top end is equipped with ventilation valves and measuring warehouses, which connects the lower end of the measuring warehouse with the leakage.Concorded in the jelly kettle.After the above structure is adopted, the pink -firing method of lithium -ion batteries in the invention is simple, the feeding system is simple, accurate, and highly reliable compared with the existing technology, which can achieve continuous production.The hammer and cross -rising air blowing structure effectively improves the efficiency of the feeding and the accuracy of the feeding.

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...
