DEDUSTING DEVICE FOR HOPPER FOR RAW MINING MINING MATERIALS Russian patent published in 2023 - IPC B65G65/32 B65G69/18 

FIELD: mining materials.

SUBSTANCE: device for dedusting the hopper for raw mining materials. Device contains a dustproof casing, a pneumatic transport line and a synchronous transportation system controlled by opening and closing valves. The synchronous transportation system contains an air intake, a movable air box, a ventilation duct, ventilation openings and valves. The movable air box is made in the form of an inverted U, mounted with the possibility of movement on the upper surface of the ventilation duct and is configured with the possibility to move synchronously with the pneumatic conveying line. Ventilation openings with valves on the upper surface of the ventilation duct connect the movable air box and the ventilation duct. The distances between adjacent ventilation holes are less than the length of the movable air box.

EFFECT: improves dust removal efficiency and reduces energy consumption.
