Description
Technical Field
The utility model relates to an Ou smelt stove tuyere coal gas plugging device.
Background
The plug of the mud jacking hole of the oxygen tuyere large sleeve of the Ou smelting furnace is damaged after being impacted by the tuyere small sleeve, and cannot be removed and replaced on line. From patent retrieval, the process method for blocking and treating the leakage pressurized gas of the blast furnace base seal plate is CN 201510756510.6. The invention relates to a process method for blocking and treating leakage pressurized gas of a blast furnace foundation sealing plate, which adopts three composite materials with different performances in a cavity of the furnace foundation sealing plate: the special solid resin composite material, the special plastic colloid material and the high-strength pouring material are used as plugging materials, after the construction is carried out by the process of plugging and treating the leakage pressurized gas of the blast furnace foundation sealing plate, the plugging sealing material is tightly combined with the surfaces of the furnace foundation sealing plate and the cement foundation pier in the protection box of the blast furnace foundation sealing plate, cracks, gaps and cavities are not generated, and the plugging sealing material has high bonding strength, toughness and rigidity, so that the internal structure of the protection box of the blast furnace foundation sealing plate is thoroughly changed, the defects generated at the joint of the blast furnace foundation sealing plate and the furnace foundation cement foundation pier are fully repaired, is combined, the problem that the leakage pressurized gas of the blast furnace foundation sealing plate is solved, and the safe operation of blast furnace production and the energy conservation are ensured. The mechanism and the treatment mode of the similar patent and the oxygen tuyere large sleeve gas leakage of the European and metallurgical furnace are different, and the safety requirement of the European and metallurgical furnace tuyere gas plugging treatment is not met.
Disclosure of Invention
The utility model aims at providing an Ouyi stove wind gap coal gas plugging device is applicable to the shutoff behind the big cover mud jacking hole coal gas leakage in Ouyi stove oxygen wind gap, reduces the risk of the coal gas leakage in the work process of Ouyi stove, can handle the big cover coal gas leakage in Ouyi stove oxygen wind gap fast on line.
The utility model provides an Ou smelt stove wind gap coal gas plugging device, including installing the oxygen rifle in the wind gap overcoat, set up a screw rod in the wind gap overcoat, the screw rod top is the arc face of cylinder, the axis of face of cylinder is mutually perpendicular with the screw rod, the screw rod top is vertical to be set up a plurality of recesses at the interval side by side, the recess is arranged along the axis direction of face of cylinder, screw rod top face of cylinder offsets with the oxygen rifle, a sleeve is being put to screw rod lower part cooperation suit, the sleeve top is fixed and is being set up an adjusting nut, the sleeve lower extreme is fixed and is being set up a packing box, be setting up the shutoff in the packing box and pack, packing box and shutoff are packed the.
When the oxygen tuyere large sleeve of the Ou metallurgical furnace needs to block coal gas, the upper end of the screw is propped against the oxygen lance, the adjusting nut is rotated, the sleeve drives the packing box to move downwards along the screw together, and the packing box blocks coal gas leakage points. The device is safe and reliable to use, reduces the production cost, reduces the labor capacity, can obviously improve and reduce the concentration of on-site coal gas, realizes the quick plugging of tuyere coal gas, and maintains the normal and stable production of the Ou-smelting furnace.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic perspective view of the present invention;
fig. 2 is a schematic view of a front half-section structure of the plugging device of the present invention.
Detailed Description
The utility model provides an Ou smelt stove wind gap coal gas plugging device, as figure 1, as shown in figure 2, including installing oxygen rifle 1 in the wind gap overcoat, set up a screw rod 5 in the wind gap overcoat, 5 tops of screw rod are the arc face of cylinder, the axis of face of cylinder is perpendicular with screw rod 5 mutually, 5 vertical side by side intervals in top of screw rod are setting up a plurality of recesses 7, recess 7 is arranged along the axis direction of face of cylinder, 5 top face of cylinder of screw rod and oxygen rifle 1 offset, 5 lower part cooperation suits of screw rod are setting up a sleeve 3, 3 tops of sleeve are fixed and are being set up an adjusting nut 4, 3 lower extremes of sleeve are fixed and are setting up a packing box 2, be setting up shutoff filler 6 in the packing box 2, packing box 2 and shutoff filler 6 are used for sealing the mud jacking hole. When the device is used, the top end of the screw rod 5 props against the oxygen lance 1, the screw rod 5 does not rotate, and the adjusting nut 4 is rotated to drive the sleeve 3 and the packing box 2 to move downwards, so that the plugging packing 6 can plug a leakage point.
