Abstract
The invention discloses a combined holder electrode sealing device for a submerged arc furnace and belongs to a part of the submerged arc furnace. The device is arranged at the upper part of a furnace cover (smoke hood) and used for sealing an electrode, so that the smoke in a hearth does not go up to the furnace cover the electrode can be guided to go up and down. Sealing rings are made of brass (H62), each sealing ring is of 30 degrees, 12 sealing rings constitute a circle, the sealing rings are divided into an upper layer and a lower layer, and a set of electrode sealing device is provided with 24 sealing rings. A lug is arranged on the outer ring surface of each electrode sealing ring, a spring gland is correspondingly arranged on a water-cooled jacket, a spring is arranged between the spring gland and the water-cooled jacket, and the electrode sealing rings tightly press the surface of an electrode protective screen by means of the spring to achieve a sealing effect.
Description
Technical field
The present invention relates to the hot stove parts in a kind of ore deposit, relate in particular to the electrode seals of the hot stove in combined holder ore deposit.
Background technology
The electrode sealing of the existing combined holder for ore furnace of China at present all adopts refractory brick (high-alumina brick) to carry out the electrode sealing, its structure such as Fig. 1, comprise the cold water jacket up and down that is combined into one, be provided with the annular tile that is placed on the electrode protection screen in the last cold water jacket, the shortcoming of this structure maximum is: (one) refractory brick is limited service life in hot environment; (2) electrode protects screen and refractory brick and friction takes place and collide the easy unfilled corner of fragment of brick and cracked in process up and down; (3) because refractory brick can not be free movable after installing, and to protect screen back thickness of slab be δ 6mm, the service life that screen is protected in long-time friction back influence; (4) refractory brick can not be docile in the protection screen periphery; sealing effectiveness is poor; effect is poorer after stove moves a period of time; must often change; it is quite big that stove is changed difficulty at run duration, can't change substantially, could change in the time of can only waiting until blowing out; not only increase labour intensity but also caused economically waste, and more can cause personal injury accident sometimes.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, improved the combined holder for ore furnace electrode seals that a kind of long service life, good sealing effect, replacing are convenient, improved the rate of starting of equipment.
Key problem in technology of the present invention is the seal member in the last cold water jacket is improved; make fixed refractory brick into movable brass sealing ring; sealing ring utilizes the strain of spring to be close to the protection screen surface by the spring capping device; reach good sealing effectiveness; concrete technical scheme is: a kind of combined holder for ore furnace electrode seals; comprise the water collar up and down that is combined into one; described water collar up and down is located on the electrode protection screen; one deck is placed in the sealing ring that electrode protection shields to it is characterized in that being built-in with at least by described upward water collar; the gland seal of sealing ring upper surface; described sealing ring is spliced by some identical arc ring pieces; described each arc ring piece outer ring surface is equipped with a projection; projection is placed in holddown spring one end; the holddown spring other end is placed on the lead of the corresponding spring capping device that arranges of water collar; described spring capping device comprises the guide pipe and the center fixation that are fixed in water collar in addition the lead gland, and both compress the holddown spring between projection and lead by the screw-threaded coupling connection.
As a further improvement on the present invention, the end of described adjacent arc ring piece is provided with the end difference that connects mutually, and end difference is provided with the projection/slotted eye that connects mutually, and described slotted eye aperture is greater than projection.By this kind setting; adjacent arc ring piece can be realized interconnecting and moving radially; effectively by the distortion of holddown spring, each arc ring piece is pressed on the electrode protection screen, and can prevents wearing and tearing that the rigid connection of arc ring interblock causes and the thrust deficiency of holddown spring.
As a further improvement on the present invention, the described sealing ring of going up in the water collar is provided with two-layer, is provided with one between the levels sealing ring and is placed in the toroidal membrane that electrode protection shields.By two-layer sealing ring is set, the holddown spring that utilizes that can realize multi-faceted multi-angle compresses, for example, if a sealing ring is spliced into by 12 arc ring pieces, average per 30 degree just are provided with holddown spring and compress, and two-layer just is 24 arc ring pieces, when the certain angle setting of staggering of each arc ring piece, just can realize on average that more low-angle just utilizes holddown spring to compress, improve leakage efficiency greatly.
As preferably, toroidal membrane is stainless steel.
As preferably, described sealing ring is brass.
Beneficial effect of the present invention: the present invention has improved electrode seals leakage efficiency and service life greatly by last cold water jacket inner seal structure is improved.

The specific embodiment
A kind of combined holder for ore furnace electrode seals; comprise the water collar up and down (001 that is combined into one; 002); described water collar (001 up and down; 002) is located on the electrode protection screen 003; the described water collar 001 of going up is built-in with the two-layer sealing ring 004 that is placed in electrode protection screen 003; 004 of levels sealing ring is provided with a toroidal membrane 005 that is placed in electrode protection screen 003; sealing ring 004 upper surface seals with gland 011; described sealing ring 004 is spliced by 12 identical arc ring pieces 041; the end of described adjacent arc ring piece 041 is provided with the end difference 411 that connects mutually; end difference 411 is provided with the projection/slotted eye (411a that connects mutually; 411b); described slotted eye 411b aperture is greater than projection 411a; can make projection 411a radially mobile in slotted eye 411b; each arc ring piece 041 outer ring surface is equipped with a projection 412; projection 412 is placed in holddown spring 006 1 ends location; holddown spring 006 other end is placed on the lead 071 of the water collar 001 corresponding spring capping device 007 that arranges; described spring capping device 007 comprises the guide pipe 072 and the center fixation that are fixed in water collar 001 in addition lead 071 gland 073, and both compress by the holddown spring 006 that screw-threaded coupling connects 071 of projection 412 and lead.Described sealing ring 004 is brass, and toroidal membrane 005 is stainless steel.
In the process that electrode moves up and down; sealing ring 004 is because the effect of holddown spring 006 and toroidal membrane 005 move left and right slightly; can make electrode protection screen 003 not be subjected to the hard extruding of external force like this and damage, and sealing ring 004 can be close to electrode protection and shield 003 periphery.
