Abstract
The utility model discloses a kind of mineral hot furnace petticoat pipe sealing top tight sealing circle, including annular insulating piece, multiple jacking mechanisms are evenly equipped with outside the annular insulating piece；The jacking mechanism Bao Junhan pedestal, the pedestal screw-internal thread fit has adjusting screw, protruding into for the inserting end of the adjusting screw is provided with block on direction, for the block between the annular insulating piece and the inserting end, the upper side and lower side of the pedestal is provided with the ring body for installing positioning.There is flue gas evolution there are smoke seal is not tight to solve the problem of the sealing device of existing mineral hot furnace.
Description
Technical field
The utility model belongs to metallurgical submerged-arc furnace equipment technology field, and in particular to a kind of sealing of mineral hot furnace petticoat pipe is with holding out against
Sealing ring.
Background technique
Water cooled seal device is widely used in mineral hot furnace, is typically mounted at the electrode at the top of petticoat pipe and reserves hole location, with
The protective case of holding system is in contact, and the gap for protective case and petticoat pipe top electrodes preformed hole to the system of holding carries out close
Envelope, prevents inner flue gas of the stove from escaping use.
The cavity that the bottom design of water-cooled sealing device has water flowing cooling, to prevent toast of the hermetic unit because of high-temperature flue gas
Roasting deformation, influences normal use, so multiple directive wheels need to be installed when design, to the protective case of stabilized holding system, together
When prevent because partially charging cause the pole heart circle variation.But water cooled seal device is generally cylindrical annular, there is water cooling cavity in bottom, leads
It is mounted in water cooling cavity top to wheel, it is (general because maintaining certain interval between sealing device and the protective case of holding system
20mm), thus when occur collapsing in furnace expect when, partial fume can be escaped often from the gap from protective case and petticoat pipe preformed hole, right
Annular pollutes.
Utility model content
The purpose of the utility model is to provide a kind of mineral hot furnace petticoat pipe sealing top tight sealing circles, solve existing mineral hot furnace
That there are smoke seals is not tight for sealing device, there is the problem of flue gas evolution.
In order to achieve the above object, the technical scheme adopted by the utility model is a kind of mineral hot furnace petticoat pipe sealing top
Close seal, including annular insulating piece, the annular insulating piece are evenly equipped with multiple jacking mechanisms outside；The jacking mechanism Bao Junhan
Pedestal, the pedestal screw-internal thread fit have adjusting screw, and protruding into for the inserting end of the adjusting screw is provided with block on direction,
Between the annular insulating piece and the inserting end, the upper side and lower side of the pedestal is provided with for pacifying the block
Set the ring body of position.
The technical solution of the utility model also has the following characteristics that
Compressed spring is provided between the side of the block and the inserting end.
The side of the block and the inserting end are provided with cylinder, and the both ends of the compressed spring are set in pair
On the cylinder answered.
Insulation board is provided between two ring bodies and the pedestal.
The annular insulating piece and the insulation board are made of material ZCuSn5Pb5Zn5.
The beneficial effects of the utility model are: the mineral hot furnace petticoat pipe sealing top tight sealing circle of the utility model, instead of
Centripetal wheel in water-cooled sealing device, principle are to be held out against annular insulating piece on the protective sleeve using jacking mechanism, can be had
It prevents the flue gas in mineral hot furnace from leaking outside to effect, external environment moulding is polluted.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of mineral hot furnace petticoat pipe sealing top tight sealing circle of the utility model；
In figure, 1. ring bodies, 2. insulation boards, 3. pedestals, 4. adjusting screws, 5. compressed springs, 6. annular insulating pieces, 7. gears
Block, 8. cylinders.
Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
A kind of mineral hot furnace petticoat pipe sealing top tight sealing circle as shown in Figure 1, including annular insulating piece 6, the annular insulating piece 6
It is evenly equipped with multiple jacking mechanisms outside；Jacking mechanism Bao Junhan pedestal 3,3 screw-internal thread fit of pedestal have adjusting screw 4, adjusting screw 4
Protruding on direction for inserting end be provided with block 7, block 7 is between annular insulating piece 6 and inserting end, the upside of pedestal 3
The ring body 1 for installing positioning is provided with downside.
The mineral hot furnace petticoat pipe sealing top tight sealing circle of the utility model, it is centripetal in water-cooled sealing device for replacing
Wheel, is respectively arranged with mounting hole in two ring bodies 1 and pedestal 4, and installation Shi Xianyong bolt passes through two ring bodies 1 and pedestal 3, then by spiral shell
Bolt is fixed on above the cooling chamber of original water cooled seal device.
When work: to ensure that annular insulating piece 6 can play good sealing effect, can respectively to each jacking mechanism into
Row holds out against adjusting, need to only screw in pedestal 3 adjusting screw 4 when being adjusted, the inserting end of adjusting screw 4 is made to push baffle 5
Advance, until baffle 5 compresses annular insulation board 6 against on the protective sleeve, forming good sealing.It needs to illustrate
It is that jacking mechanism is answered equal angular in the outside for being circumferentially distributed in annular insulating piece 6, it is ensured that the uniform force of annular insulating piece 6,
Good sealing is formed between protective case.In addition ring body 1 install when, generate all gaps use ceramic fiber cotton into
Row sealing guarantees that insulation is good.
When not needing the sealing of ring packing block 6, release adjusting can be carried out to each jacking mechanism respectively, carry out release tune
Adjusting screw 4 need to only be screwed out in pedestal 3 when section, make separate the baffle 5 of adjusting screw 4, hereafter annular insulation board 6 will not be followed by
Continuous compression on the protective sleeve, can carry out subsequent replacement or other operations.
As shown in Figure 1, being provided with compressed spring 5 between the side and inserting end of block 7, on the one hand pass through compressed spring 5
Effect can make the stress of baffle 7 more uniform, and when movement will not shift, and when on the other hand not needing to hold out against, block 7 can be
The elastic force of compressed spring 5 acts on lower Rapid reset.
As shown in Figure 1, the mounting means of compressed spring 5 as one preferred, it can be in the side of block 7 and inserting end point
It is not provided with cylinder 8, the both ends of compressed spring 5 need to be only set on corresponding cylinder 8 by when installation.
As shown in Figure 1, being provided with insulation board 2 between two ring bodies 1 and pedestal 3, flue gas can be further prevented to leak outside.
As shown in Figure 1, annular insulating piece 6 and insulation board 2 are made of material ZCuSn5Pb5Zn5, heat dissipation good every magnetic
Fastly.
Therefore, the mineral hot furnace petticoat pipe sealing top tight sealing circle of the utility model, using jacking mechanism by annular insulating piece
The flue gas that holding out against can be effectively prevented on the protective sleeve in mineral hot furnace leaks outside, and avoids polluting external environment moulding.
