Technical Brief
—The production process of lithium batteries can be divided into front-end and back-end processes. The main procedures of the front-end process include mixing, coating, rolling, slitting, sheeting, die-cutting, etc., involving equipment such as mixers, coating machines, rolling presses, slitting machines, sheeting machines, and die-cutting machines. The slurry mixing involves mixing positive and negative solid battery materials evenly and then adding solvent to stir into a slurry. Coating involves evenly applying the mixed slurry onto metal foil and drying it to produce positive and negative electrodes. Rolling further compresses the coated electrodes to enhance the battery's energy density.
—In the production of lithium batteries, from the processes of material mixing, coating, rolling, to winding and welding, fine powders or oil fumes are generated. The dust removal in these processes is characterized by low air volume, fire prevention, explosion-proof, and high-efficiency purification. Based on the characteristics of the smoke and dust at each workstation, Tenzon has configured different fireproof or explosion-proof high-efficiency dust collectors such as MULT, HT, and LT, utilizing filter cartridges and filter plates as the filtering elements.
Main Safety Configurations
 |
—For combustible dust, do explosion-proof zoning analysis, configure dust system. Main configs: —The airflow velocity in the duct is higher than 23m/s; —Grounding of air ducts and dust collectors; —Large-angle ash hopper to prevent dust accumulation; —Star discharge valve; —The dust collector is equipped with a non-flame explosion vent or a directional explosion relief window (in a safe direction). —The intake duct is equipped with a safety explosion isolation valve. —The structure of the dust collector and the air intake duct is reinforced for explosion prevention. —Explosion-proof electric control cabinet (based on explosion-proof zoning). —Spark-resistant material for the fan inlet. —The fan motor and the discharge valve motor adopt explosion-proof motors (based on explosion-proof zoning).
