AI Technical Summary
Existing powder feeding equipment suffers from low efficiency and poor performance in dust prevention and removal, especially in capturing fine dust particles smaller than 5 micrometers. Furthermore, the dust prevention structure has leakage points, leading to severe dust diffusion, which affects the health of operators and the operation of the equipment.
An arc-shaped dust cover forms a sealed space, which is combined with centrifugal filtration components and atomizing spray components. Through negative pressure extraction and the arrangement of atomizing nozzles in the same direction as the airflow, pre-wetting and agglomerating of dust and efficient centrifugal separation are achieved, especially for the deep purification of fine dust.
It significantly improves dust removal efficiency, reduces dust leakage rate, enhances the capture efficiency of fine dust below 5 micrometers, achieves deep dust purification, and improves the production environment and equipment operation stability.
