Blowing and suction dust removal device for cleaning powder on surface of plate
In order to improve the safety performance and quality of Li-ion battery,a blowing and suction dust removal device based on high-frequency airflow is designed.The Li-ion battery anode plate and micron-sized copper powder are selected as the research object,the dust removal effect is compared with that of air knife and suction hood.When the plate running speed is 0.3 m/s,the dust removal ratio is decreased from 97.04% to 71.88% with the working distance of the blowing and suction dust removal device increase from 2 mm to 10 mm.When the working distance is 2 mm,the dust removal ratio is decreased from 97.96% to 95.29% with the running speed of the battery plate increase from 0.1 m/s to 0.5 m/s.With the increase of the working positive pressure,the dust removal performance is increased,the dust removal ratio on the surface of the electrode reaches to 99.27% with the working positive pressure at 14 kPa.Compared with the air knife and suction hood,the blowing suction dust removal device can achieve a higher dust removal rate with lower power consumption.
