Description
Technical field
The utility model belongs to the parts on the metallurgy industry oxygen bottom blowing smelter, is specifically related to the oxygen lance of oxygen bottom-blowing furnace stationary installation.
Background technology
One general configuration, 4-6 oxygen rifles in oxygen bottom blowing smelter bottom spray into industrial pure oxygen by the oxygen rifle in stove, driving the vigorous agitation of melt in the molten bath, thereby reach the purpose of intensified smelting.Therefore, the oxygen rifle is one of technological core of oxygen enriched molten bath lead smelting process.Because the oxygen rifle will insert melt inside, melt temperature is all up to more than 1000 ℃ in the molten bath when normally producing, and oxygen rifle skin passes into N usually
2And the mixture of water improves the work-ing life of oxygen rifle as the shielding gas of oxygen rifle with this.In any case protection, the work-ing life of oxygen rifle is eventually limited, and is short then used only 3-5 days, long then with regard to one month; Therefore the work of changing the oxygen rifle is absolutely necessary.At present known oxygen bottom blowing smelter oxygen rifle is to adopt bolt and nut to connect with being connected of body of heater, dismounting and fixed installation will be carried out rigid operation with pipe wrench, spanner etc., in running order oxygen bottom blowing smelter threaded connection place temperature is high, often burn to death, dismounting is to the easy injury such as oxygen rifle core, screw thread by force.Sometimes it is very difficult to change the oxygen rifle, many times all can pull out out, whole rifle all can only be pounded more to renew rifle in the stove, and very large to the damage of oxygen rifle brick, each replacing all needs to waste the plenty of time, manpower, and labour intensity is large.And the production of oxygen bottom blowing smelter, what need is stable continuity; Change the oxygen rifle time and drag longly, often cause the furnace temperature fluctuation to system, not only increased energy consumption, also had a strong impact on output.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiency of prior art, and a kind of oxygen lance of oxygen bottom-blowing furnace stationary installation is provided, can solve the oxygen rifle and change complicated, difficult technical problem, and operational safety is convenient, and it is short to change the oxygen rifle time, can not cause system's furnace temperature fluctuation.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of oxygen lance of oxygen bottom-blowing furnace stationary installation, to divide into large flange capping at the ring seal water-cooled box body in oxygen lance of oxygen bottom-blowing furnace zone, secondary side's cover plate is divided in large flange capping, the center of secondary side's cover plate arranges minor flaps, the center of minor flaps and the welding of oxygen gun barrel one; Wherein, the use bolt and nut is connected between large flange capping and the ring seal water-cooled box body; Push mutually by the 1# bolt between large flange capping and the secondary side's cover plate and connect; Push mutually by the 2# bolt between secondary side's cover plate and the minor flaps and connect; It is to fix the 1# bolt seat that keyhole is opened in four centres with the distribution of centrosymmetry ground in large flange capping that described 1# bolt pushes connection mutually, all has a 1# bolt to pass this keyhole on each 1# bolt seat, and the wedge nose part that exposes is pressed on the cover plate edge, secondary side; Described 2# bolt pushes mutually that to connect be to distribute symmetrically with both sides to fix the 2# bolt seat that keyhole is opened in four centres on secondary side's cover plate, all have a 2# bolt to pass this keyhole on each 2# bolt seat, and the wedge nose part that exposes is pressed on the minor flaps edge.
Use the utility model, when needs are torn the oxygen rifle open, with hammering the wedge nose part that raps four 2# bolts into shape, allow it be retracted in the keyhole of 2# bolt seat, take down oxygen rifle together with minor flaps from the oxygen bottom blowing furnace bottom, finish fast dismantling oxygen rifle process; When needs dress oxygen rifle, to insert together with the gun barrel of minor flaps oxygen rifle in the oxygen bottom blowing furnace bottom, allow minor flaps be close to secondary side's cover plate, with the 2# bolt in four 2# bolt seats on secondary side's cover plate with the hand push support minor flaps of starting going to a nursery, then rap four 2# bolts with hammer, the wedge nose part that exposes is pressed on the minor flaps edge, finishes rapid dress oxygen rifle process.
If when needing maintenance to tear the oxygen gun water-cooling box body open, with hammering the wedge nose part that raps four 1# bolts into shape, allow it be retracted in the keyhole of 1# bolt seat, take down secondary side's cover plate together with the oxygen rifle of minor flaps from the oxygen bottom blowing furnace bottom, finish fast dismantling oxygen rifle process; Otherwise, can be fast with secondary side's cover plate together with the oxygen rifle of the minor flaps oxygen bottom blowing furnace bottom of packing into.
If when overhauling oxygen rifle water jacket, the bolt and nut that then needs to tear open between large flange capping and the ring seal water-cooled box body is processed.
Compared with prior art, the beneficial effects of the utility model are, the utility model oxygen rifle pushes connection mutually with being connected by bolt and nut+1# and 2# bolt of oxygen bottom blown furnace, the replacing of oxygen rifle is become to be easy to fast, operational safety is convenient, change only 1-2 minute oxygen rifle time, can not cause to system furnace temperature fluctuation.
