Abstract
The utility model discloses an oxygen gun mouth sealing plug of an energy-saving and low-consumption rotary furnace, which is used for reducing consumption of nitrogen of oxygen gun mouth sealing. The oxygen gun mouth sealing plug of the energy-saving and low-consumption rotary furnace comprises a round hole and an plug body of an annular groove, the round hole is formed at the middle of the oxygen gun mouth sealing plug, the upper plane of the plug body is provided with a set of sealing cavity, the plug body is arranged on an oxygen gun mouth, an oxygen gun passes through the round hole at the middle and is supported by a baffle plate, and the baffle plate is welded on the oxygen gun. The oxygen gun mouth sealing plug of the energy-saving and low-consumption rotary furnace has the advantages that an environment-friendly effect is improved, and nitrogen consumption is reduced.
Description
Technical field
This use is novel to relate to a kind of converter steelmaking field devices, is anti-excessive energy-conservation, the low-coumption converter oxygen gun mouth sealing plug of block muzzle place flue gas.
Background technology
Energy-conservation, low-coumption converter oxygen gun mouth sealing plug is installed on the oxygen muzzle of converter evaporation cooling air flue, the flue dust that produces when smelting and on the flame of scurrying block, play stop that flue gas, flame are excessive, the effect of protection environment and miscellaneous equipment.Original sealing plug is a pyramidal structure, round-meshed cock body and guide section in the middle of comprising, and cock body is contained on the oxygen rifle through the intermediary circle hole sleeve, and is held by the baffle plate on the oxygen rifle.Owing between cock body intermediary circular hole and the oxygen rifle slit is arranged, when blowing, scurry out from slit between the two like this with regard to some flue gas and flame, pollute site environment, also can burn out oxygen hose when serious.
The utility model content
The main purpose of the utility model is to solve gap, cock body and guide section junction flue gas and the excessive problem of flame between oxygen rifle and the cock body, and a kind of energy-conservation, low-coumption converter oxygen gun mouth sealing plug is provided, and reduces the nitrogen usage quantity of oxygen muzzle sealing.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of energy-conservation, low-coumption converter oxygen gun mouth sealing plug, it is the middle cock body that circular hole, ring groove are arranged, planar band one cover enclosed housing on the cock body, cock body is installed on the oxygen muzzle, and the oxygen rifle passes from the intermediary circular hole, and holds through the baffle plate that is welded on the oxygen rifle.
Said cock body comprises the close-fitting with it guide section of ball sealer and ball sealer outside, and enclosed housing is installed in the junction of guide section top and oxygen rifle.
Said enclosed housing mainly is made up of snap ring, slip-knot bolt, asbestos twine, strap and adjusting bolt, and wherein snap ring is installed in the guide section top through the slip-knot bolt, in snap ring, is provided with asbestos twine, and asbestos twine is connected with strap, and strap is connected with the adjusting bolt.
Said ring groove is arranged on the inwall of ball sealer and around the oxygen rifle.
The utility model is made up of several parts such as guide section, ball sealer, snap ring, cover plate, straps.The gas of HTHP rises along gasification cooling flue when the oxygen rifle blows, and outwards overflows at oxygen muzzle place.The gap of the gas of HTHP between oxygen rifle and ball sealer forms turbulent flow to excessive in ring groove when excessive gas rises to ring groove, thereby increase the rising resistance of follow-up excessive gas; The partial fume that continues to rise can enter into the annular seal space of being made up of cover plate, asbestos twine, slip-knot bolt, snap ring, strap, thereby has effectively stoped the excessive of flue gas because of asbestos twine closely contacts with the oxygen rifle.The elasticity of adjusting strap through the adjusting bolt is to regulate the exposure level between asbestos twine and the oxygen gun body.Because of asbestos twine belongs to elastomerics, the frictional force between asbestos twine and the oxygen rifle is much smaller than the gravity of sealing plug, so the oxygen rifle can free lifting in converter steelmaking process.Because of ball sealer and guide section have adopted hemispherical dome structure, thereby can tight cooperation effectively avoid flue gas excessive between the two from junction between the two.
The beneficial effect of the utility model is: simple in structure, easy to use, and good sealing effect.
Description of drawings
Fig. 1 is the sectional view of the utility model.
Fig. 2 is the vertical view of the utility model.
Among the figure, 1 oxygen rifle, 2 guide sections, 3 ball sealers, 4 snap rings, 5 cover plates, 6 asbestos twines, 7 slip-knot bolts, 8 are regulated bolt, 9, ring groove, 10 baffle plates, 11 straps.
Embodiment
Do further explanation according to accompanying drawing and specific embodiment to this use is novel below:
As shown in Figure 1, energy-conservation, low oxygen consumption muzzle sealing plug is made up of guide section 2, ball sealer 3, snap ring 4, cover plate 5, asbestos twine 6, slip-knot bolt 7, strap 11, adjusting bolt 8.Guide section 2 is installed on 1 mouthful in the oxygen rifle, and sealing plug is sleeved on the oxygen rifle 1, and has baffle plate 10 to hold, thereby can be with 1 one liftings of oxygen rifle.When 1 blowing of oxygen rifle; Through the tight cooperation of guide section 2, ball sealer 3, excessive gas forms turbulent flow and increases the rising resistance of follow-up excessive gas and realize stoping the purpose that flue gas is excessive, reduce nitrogen consumption by the annular seal space that cover plate 5, asbestos twine 6, slip-knot bolt 7, snap ring 4, strap 11 are formed in ring groove 9.The degree of tightness of asbestos twine 6 is adjusted through strap 11 by regulating bolt 8.
