Abstract
The utility model discloses an electric-furnace dust hood for nonferrous metal smelting. The electric-furnace dust hood is composed of an electric-furnace platform, a flat cylindrical base, a flue and the like. The flat cylindrical base is identical to an electric-furnace opening in appearance, the flue is communicated with the flat cylindrical base, two connecting shafts are arranged on the top side of the flat cylindrical base, the bottoms of the connecting shafts are fixedly connected with the electric-furnace platform, two semicircular dust hook covers cover the position of the upper opening of the flat cylindrical base and are hinged to the connecting shafts, and the flat cylindrical base is hermetically connected to the outer flange of the electric-furnace opening. The base of the dust hood is designed around the electric-furnace opening, the outlet portion of the electric-furnace opening is communicated with the dust flue, and after the dust hood cover is covered, flue gas leakage can be effectively avoided. As it shows in the test, convenience in furnace cleaning is achieved, operation efficiency can be obviously improved, flue gas absorption effect is good, processing of smoke is facilitated for a dust removing device, and working environment and atmospheric environment can be improved. Compared with the prior art, the electric-furnace dust hood is greatly improved.
Description
Technical field
The utility model relates to non-ferrous metal metallurgy dedusting field, relates in particular to a kind of non-ferrous metal metallurgy electric furnace dust arrester.
Background technology
In the smelting process of non-ferrous metal, can produce some flue dust, these flue dust of generation are collected by dust excluding hood, and blower fan is pumped, and, discharge after deduster is processed to deduster by pipeline.In whole process, the collection of flue gas is the crucial first step, if flue dust collecting is not thorough, dedusting also will lose meaning.At present, the dust excluding hood that in production, electric furnace uses uses iron plate to make, be bent into cylindrical shape dust excluding hood according to fire door bore, at top closure, cylindrical shape dust excluding hood radially four/part adopts Activities Design, weld handle above, to according to requirements feed in raw material and prepurging work under the prerequisite of movable dust removal cover not.But this structure dust excluding hood is high apart from fire door, and it is large, yielding to take up room, heavier when use, is not easy to rotate, and because cover itself is higher, petticoat pipe spatial volume is excessive, and flue dust is not easy to drain and occur the defect that part flue dust is excessive.
Summary of the invention
The utility model is for the deficiencies in the prior art, provides one to take up room less, not yielding, is easy to rotate, and is beneficial to the non-ferrous metal metallurgy electric furnace dust excluding hood of collecting and discharging fume.
The utility model is realized by following technical scheme, non-ferrous metal metallurgy electric furnace dust excluding hood, the flat drum shape base matching by electric furnace platform, with electric furnace mouth profile, the flue being communicated with flat drum shape base etc. form, it is characterized in that, be provided with two connecting axles at described flat drum shape base top avris, connecting axle bottom is firmly connected with electric furnace platform, two semicircle dust excluding hoods cover and are overlying on flat drum shape base upper opening place, described semicircle dedusting cover cap and described connecting axle are hinged, and described flat drum shape base is connected with electric furnace mouth outer rim secure seal.
The beneficial effects of the utility model are, ring electric furnace mouth design dust excluding hood base, and its exit portion is communicated with dust-removing flue, and flue gas enters dust-removing flue through the collection of dust excluding hood base, and base seal is welded in fire door outer rim.The dedusting cover cap of prior art is modified into two semicircular split type, Convenient switch uses.After dedusting cover cap is built, can effectively avoid flue gas excessive, dedusting cover cap between centers coordinates closely, closes flexibly, and does not affect the installation of crucible.Through test, the utility model not only prepurging is convenient, and operating efficiency also obviously improves, and smoking effect is good, facilitates cleaner to process flue dust, improves working environment and atmospheric environment.It is the once larger improvement to prior art.
