Composite low-resistance high-efficiency paint mist filter paper box

Abstract

The utility model discloses a composite low-resistance high -efficient paint mist filter paper box relates to filter technical field, including outer box shell, and the outer box shell is installed with the front stage labyrinth type filter unit and the rear stage honeycomb composite filter unit in proper order from input end to output end, and the output of front stage labyrinth type filter unit is precisely docked with the input of rear stage honeycomb composite filter unit, and the outer box shell is the hollow rectangular frame that multiple corrugated paperboard adhesion formed, is used for encapsulating, fixed inside front stage labyrinth type filter unit and rear stage honeycomb composite filter unit and provides support, and front stage labyrinth type filter unit is formed by the staggered stack adhesion of multiple corrugated paperboard, and front stage labyrinth type filter unit has continuous zigzag airflow channel, is used for low -resistance pre -filtration to contain paint mist airflow, intercepts big particle paint mist and reduces airflow impact, and rear stage honeycomb composite filter unit is composed of multiple honeycomb paper net, and multiple honeycomb paper net is used for to the accurate filtration of the airflow after the filtration of front stage labyrinth type filter unit, and high -efficient intercepts fine paint mist particle.
