Abstract

The invention relates to a semi-closed type silver casting intermediate-frequency furnace movable smoking device which comprises an exhaust fume collecting hood (1), a ventilation dust removal system(2) and an exhaust tube; the exhaust tube is divided into a fixed tube (3) and a movable tube (4), and the fixed tube and the movable tube are in sealed connection through a flange plate connector (5); the side, at the end of the fixed tube (3), of a flange plate and the side, at the end of the movable tube (4), of the flange plate are movably connected through a hinge (6), a suspension point (7)is perpendicularly arranged overhead the hinge (6), and a suspension lug (8) is arranged above the exhaust fume collecting hood (1); a chain or a steel wire pull rope (9) is arranged between the suspension point and the suspension lug (8) for traction. The device is simple in structure, convenient to produce and operate, durable and stable.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment for intermediate frequency furnaces, in particular to a semi-closed silver melting and casting intermediate frequency furnace mobile smoking device. Background technique [0002] In the production of electrolytic and refined silver smelting, it is necessary to use intermediate frequency furnaces to melt silver and cast anode plates for production. Since the crude silver raw materials contain a large amount of impurities, smoke and dust will be generated during silver melting and smelting, which will pollute the site environment; usually an umbrella-shaped ventilation is set above the entrance of the intermediate frequency furnace cover. However, due to the furnace opening or other maintenance operations, personnel must stand above the intermediate frequency furnace mouth, which affects the operation of the operators. [0003] On February 22, 2017, the Chinese utility model patent a...
