The utility model discloses a double -ply bellows pressure ring of hot stove in large capacity ore deposit, including annular water -cooling box and copper tile closing device, copper tile closing device is including setting up in annular water -cooling box one side and imbed the bellows closing device of annular water -cooling box and set up in the top of the embedding annular water -cooling box for bellows closing device one side diagonal opposite side, bellows closing device and top one -to -one, be equipped with the copper tile closing device of two pair at least upper and lower ranges on the annular water -cooling box, whenever, include two at least bellows closing device to copper tile closing device. The utility model discloses a two pair upper and lower bellows closing device implement two application points to copper tile and compress tightly, and copper tile is stressed even reliably, solved that the single -point compresses tightly that copper tile leads to and the electrode between the occurence of failure probability reduction of beating the arc produces, prolonged copper tile's life to a certain extent, improved the operation rate of electric stove.
Description
Technical field
The utility model relates to a kind of pressure rings, particularly a kind of double-ply bellows pressure rings of large-capacity ore furnace.
Background technology
For mineral hot furnace, electrode hold tightly basic adopt Conducting copper tile hold mode tightly, the pressure rings of therefore holding brasses tightly also becomes one of critical component.
Pressure rings is the critical piece of mineral hot furnace conducting system, is also the critical component of holding and degree of tightness electrode simultaneously, and its effect compresses brasses to hold electrode tightly, and electric current is entered in electric furnace uniformly by brasses and electrode.
At present, mode held tightly by the brasses of domestic and international employing: one is taper ring type, the power which acts on brasses is uneven, cause the contact of brasses and electrode also uneven, contact resistance is caused to increase, imbalance, easily causes brasses and electrode to beat the accidents such as arc, directly affects the operating rate of electric furnace.Two is hydraulic oil cylinder types, and this kind of mode dismounting is inconvenient, and failure rate is high, maintenance difficult.
Now due to domestic to expanding economy and the requirement to metallurgy industry, various mineral hot furnace capacity expands gradually, conductive component also increases thereupon, traditional design, no matter take the pressure rings of what form, it is all the pressure rings of the individual layer adopted, because present furnace volume strengthens, the size also corresponding increase of Conducting copper tile, traditional design existing defects, its defect is exactly be all single-contact between pressure rings and brasses, such form is used on jumbo electric furnace, brasses discontinuity can be caused, the contact of brasses and electrode is uneven simultaneously, easily cause the generation of beating the accidents such as arc.
Summary of the invention
Goal of the invention: the purpose of this utility model is that solving present furnace volume strengthens, the size also corresponding increase of Conducting copper tile, it is all single-contact between existing pressure rings and brasses, such form is used on jumbo electric furnace, brasses discontinuity can be caused, the contact of brasses and electrode is uneven simultaneously, easily causes the problem of the generation of beating the accidents such as arc.
Technical scheme: the utility model provides following technical scheme: a kind of double-ply bellows pressure rings of large-capacity ore furnace, comprise annular water-cooled casing and brasses hold down gag, described brasses hold down gag comprises and is arranged at annular water-cooled casing side and embeds the bellows hold down gag of annular water cooling box body and be arranged at the top of the embedding annular water cooling box body relative to bellows hold down gag side diagonal opposite side, bellows hold down gag and top one_to_one corresponding, described annular water-cooled casing is provided with at least two to the brasses hold down gag be arranged above and below, two bellows hold down gags connection place straight lines that the described two pairs of brasses hold down gags be arranged above and below are positioned at the same side are vertical with annular water-cooled casing top planes, described often pair of brasses hold down gag comprises at least two bellows hold down gags.
As optimization, described annular water-cooled casing comprises upper cover plate, base plate, interior plate, peripheral board and dividing plate, upper cover plate, base plate, interior plate close into confined space with peripheral board, annulus water-cooled casing is provided with hanger, annulus water-cooled casing is divided into two-layer along direction, cross section, every layer arranges several bellows hold down gags, and bellows hold down gag is fixed in annular water-cooled casing by interior plate and peripheral board.
As optimization, described annular water-cooled casing is stainless steel annular water cooling box body.
As optimization, described bellows hold down gag comprises expansion box and the hydraulic system of many group bellows compositions.
As optimization, described hydraulic system comprises oil inlet pipe, water-stop sheet, water inlet pipe and return pipe.
As optimization, described bellows group number is identical with brasses block number.
Operation principle: expansion box is exactly a kind of hydraulic cylinder of special construction in fact, instead of the cylinder body of hydraulic cylinder with bellows.When hydraulic system gives pressure, bellows extends, and drive compression box to compress brasses, when removing pressure, bellows rebounds by its own resilient and unclamps brasses.Sylphon seal is good, can not leakage of oil.
Beneficial effect: the utility model is relative to prior art: the utility model adopts upper and lower two pairs of bellows hold down gags, implement two application points to brasses to compress, brasses pressure is evenly reliable, solve single-point compression brasses to cause producing the contingency occurrence probability reduction of beating arc between electrode, extend the useful life of brasses to a certain extent, improve the operating rate of electric furnace.Sylphon seal is good, can not leakage of oil.
