AI Technical Summary
Technical Problem
The roasting furnace generates a large amount of dust during the falling of the filling material, resulting in serious dust exceeding the standard in the working environment, affecting work safety and environmental hygiene.
Method used
Main ventilation ducts and U-shaped ventilation ducts are set up around the furnace chamber and equipped with dust collectors. Dust is drawn in through the air inlet and treated by the dust collectors. Combined with electric cylinders to control the opening and closing of the air ducts, the air volume configuration is optimized to improve the dust removal effect.
Benefits of technology
It effectively reduced the spread of dust, lowered surrounding dust pollution, improved the working environment, and increased dust removal efficiency.

Abstract
The utility model discloses a roasting furnace filler dust removal device which comprises a furnace chamber, a flame path wall, a plurality of parallel rectangular furnace chambers which are defined by the flame path wall and separated, a main ventilating duct is arranged above the same side ends of the plurality of furnace chambers, and a U-shaped ventilating duct is arranged above the periphery of each furnace chamber. The two ends of any U-shaped ventilating duct are communicated with the side wall of the main ventilating duct; a plurality of air inlets are respectively formed in the side wall, facing the furnace chamber, of the U-shaped ventilating duct; one side of the main ventilating duct is communicated with an auxiliary ventilating duct, an air outlet is formed in the top of the auxiliary ventilating duct, a dust suction port of the dust remover is connected with a corrugated pipe, and the corrugated pipe is fixedly connected to the air outlet through a pipe hoop; a plurality of electric cylinders are arranged on the side wall of the main ventilating duct in a penetrating mode, a cover plate is fixed to the telescopic end of each electric cylinder, a ventilating window body is fixed to the end of the U-shaped ventilating duct, and the cover plates are attached to the ventilating window body. The furnace has the advantages that raised dust at the furnace mouth can be sucked into the main ventilating duct and the U-shaped ventilating duct and is finally removed by the dust remover, diffusion is reduced, and surrounding dust pollution is reduced.
