Abstract

The invention relates to a waste gas dust recovery device for a forging blank electric slag furnace. The waste gas dust recovery device for the forging blank electric slag furnace comprises an annularnegative pressure ring, an annular base plate and a necking mechanism; a negative pressure cavity is formed in the negative pressure ring, negative pressure openings are formed in the inner wall of the negative pressure ring, the negative pressure ring is in threaded connection with air opening adjusting bolts, heads of the air opening adjusting bolts are provided with air volume plugs, and one side of the negative pressure ring is provided with an air suction main pipe communicating with the negative pressure cavity; and the necking mechanism comprises a top plate and a bottom plate, slidinggrooves are formed in the top plate and the bottom plate correspondingly, blocking plates are arranged between the top plate and the bottom plate, sliding pins are arranged on the blocking plates, each blocking plate is a flat plate with at least two adjacent edges as straight edges, the two straight edges of each blocking plate correspondingly serve as a driving edge and a pressed edge, and thepressed edge and the driving edge of every two adjacent blocking plates are attached to each other. According to the waste gas dust recovery device, gaps around electrodes are reduced through the necking structure, so that waste gas is prevented from escaping from the peripheries of the electrodes; and negative pressure nozzles are uniformly distributed around the negative pressure ring and are matched with the necking mechanism to form a negative pressure zone at an opening of a crystallizer, and thus the waste gas dust recovery device does not need to be disassembled and assembled during feeding and discharging.

Description

technical field [0001] The invention relates to the technical field of waste gas and dust recovery devices for electroslag ingots, in particular to a waste gas and dust recovery device for forging rough electroslag furnaces. Background technique [0002] Large-scale cylindrical forging blanks with high quality requirements are usually formed by electroslag furnaces during production. When the electroslag furnace is working, dust or exhaust gas easily escapes from the top outlet of the crystallizer. Air nozzle, this method has limited effect and high noise. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a waste gas dust recovery device for forging blank electroslag furnace. [0004] The technical solution adopted by the present invention to solve the technical problem is: a waste gas and dust recovery device for forging blank electroslag furnace, comprising an annular negative pressure ring,...
