Abstract
An electrode sealing device for a submerged arc furnace is arranged on a smoke helmet of an electrode and comprises a water-cooling sealing sleeve, a plurality of electrode adjusting devices arranged around the circle center of the electrode, an elastic adjusting device arranged on the water-cooling sealing sleeve and a plurality of electrode guiding devices. The elastic adjusting device comprises a high-density cement asbestos brick, a high-temperature-resistant cloth inserted hose and a sealing brick pressing plate. The high-density cement asbestos brick and the high-temperature-resistant cloth inserted hose are arranged in the water-cooling sealing sleeve, one end of the high-density cement asbestos brick makes contact with the high-temperature-resistant cloth inserted hose, and the other end of the high-density cement asbestos brick is pressed in a protecting sleeve. The high-temperature-resistant cloth inserted hose is arranged in the water-cooling sealing sleeve, and one end of the high-temperature-resistant cloth inserted hose abuts against the inner wall of the water-cooling sealing sleeve. The electrode sealing device has the good properties of heat preservation, heat insulation, insulation, corrosion resistance and the like.
Description
Technical field
Basis is practical belongs to mineral hot furnace device electrode sealing device, belongs to mineral hot furnace device fabrication industry.
Background technology
In mine heat furnace smelting ferrosilicon process, a large amount of high-temperature smoke can be produced, if seal bad between bell and electrode, make the flue gas in burner hearth excessive from bell, the problem brought is: one, can make the cable on petticoat pipe top cover, the equipment such as short net, carrying cylinder hanging scorch by high-temperature flue gas for a long time, easily break down and reduction of service life.Two, flue dust fills the air, and worsens the work working condition of workman, and three, sealing effectiveness is bad, is unfavorable for the recovery of flue dust.Current electrodes in mine hot stove sealing device, great majority are that copper sealing ring-spring regulates hermetically-sealed construction.The defect of this kind of device is: one is that the cost of copper sealing shroud is very high, and the first input cost of enterprise is high.Two is spring regulating device complex structures, produce and maintenance cost higher.Three is be circumferentially that loose point regulates at sealing shroud, and do not reach the object of even regulation power, electrode is in use eccentric along with the increased frequency pressing, pull out, bad stability.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of mineral hot furnace electrode seals with premium properties such as insulation, heat insulation, insulation, corrosion resistants.
For realizing the object of the invention, provide following technical scheme: mineral hot furnace electrode seals, be arranged on the petticoat pipe of electrode, comprise water-cooled seal sleeve, several electrode regulators arranged around the electrode center of circle, be arranged at water cooled seal and put flexible adjustment device and several electrode guides, it is characterized in that flexible adjustment device comprises weighted cement asbestos brick and high-temperature heat-resistance fabric hose and seals brick pressing plate, described weighted cement asbestos brick, high-temperature heat-resistance fabric hose is arranged in water-cooled seal sleeve, weighted cement asbestos brick one end contacts with high-temperature heat-resistance fabric hose, the other end is pressed in protective sleeve, described high-temperature heat-resistance fabric hose is as in water-cooled seal sleeve, one end is butted on water-cooled seal sleeve inwall.
Beneficial effect of the present invention: 1, high-temperature heat-resistance fabric hose is rubber tube, cheap, compared with the spring regulating device of copper sealing ring, need not process, and buy just energy use, initial investment expense is low.2, rubber tube is a circumference entirety, and integrally-regulated performance is better, and whole electrode can be made more stable, makes that guider thrust adjustable extent is large, apparatus adaptability good.3, because structure is simple, the maintenance when equipment runs, recondition expense are relatively low.4, weighted cement asbestos brick be high temperature resistant, insulation, environmental protection ceramic fiber sheet material, cost is more cheap than copper sealing shroud, initial estimate: the weight of a set of copper sealing shroud is 260kg, by minimum cost 260kg × 55 yuan/kg=14300 unit, stove=3 × 14300 yuan=42900 yuan.As long as sealing shroud 260kg × 25 yuan of a set of brick and rubber tube combination/kg=6500 unit, stove 6500 × 3=19500 unit, a stove just can save 42900-19500=23400 unit.5, failure rate is low, improves electric furnace operating rate.

Detailed description of the invention
Embodiment 1: mineral hot furnace electrode seals, be arranged on the petticoat pipe 2 of electrode 1, comprise water-cooled seal sleeve 3, 2 electrode regulators 4 arranged around electrode 1 center of circle, be arranged at flexible adjustment device 5 and 6 electrode guides 7 on water-cooled seal sleeve 3, flexible adjustment device 5 comprises weighted cement asbestos brick 5.1 and high-temperature heat-resistance fabric hose 5.2 and seals brick pressing plate 5.3, described weighted cement asbestos brick 5.1, high-temperature heat-resistance fabric hose 5.2 is arranged in water-cooled seal sleeve 3, weighted cement asbestos brick 5.1 one end contacts with high-temperature heat-resistance fabric hose 5.2, the other end is pressed in protective sleeve 8, described high-temperature heat-resistance fabric hose 5.2 is as in water-cooled seal sleeve 3, one end is butted on water-cooled seal sleeve 3 inwall.
Electrode regulator 4 in above-described embodiment, its structure of electrode guide 7 are content of the prior art, identical with the electrode regulator of prior art accompanying drawing 1 ~ 4 in the application, electrode guide, no longer repeated description in the application, the application mainly improves and is the copper of present technology sealing ring-spring to regulate the structure of sealing to change the structure of the flexible adjustment device 5 of the application into, all the other are prior art, without any change.
