Abstract
The utility model discloses a submerged arc furnace electrode water-cooling protective jacket including an outer jacket body, a flange plate, annular water channels, a vertical water channel, a water pipe, a fireproofing asbestos rubber pipe and a separation channel. One end of the outer jacket body is provided with the flange plate. The annular water channels are annular cooling water pipelines welded on the inner wall of the outer jacket body. Two adjacent annular water channels are separated through a separation plate. Each separation plate is provided with a notch. The notch is the only communication portion of two adjacent annular water channels. The notches in two adjacent separation plates are staggered by 180 degrees. A separation channel is arranged between the annular water channels and the flange plate. According to the submerged arc furnace electrode water-cooling protective jacket, the main cooling water channels are arranged in an annular manner, the weld joint temperature difference is changed gradually, so the welding firmness can be enhanced, and according to the annular design, the welding area is reduced as far as possible while ensuring the largest cooling area, and the machining cost can be reduced; two circulation water channels can be used to increase the flow of the cooling water and ensure the cooling effect.
Description
Technical field
The utility model belongs to metallurgical equipment field, is specially a kind of electrodes in mine hot stove water-cooling protective sleeve.
Background technology
Electrode water-cooling protective sleeve is the key equipment in closed submerged stove electrode column.In mine heat furnace smelting process, electrode column bottom device is exposed in the high-temperature furnace gas of 1000 DEG C of left and right, in the mineral hot furnace of especially smelting at submerged arc, electrode need to insert in the high-temp. furnace material of 1500 DEG C of left and right of semi-molten state, under this hot environment, and very easily scaling loss of electrode column equipment.Therefore, the protective sleeve of claimed electrode bottom device can adapt to this condition of work.The effect of electrode water-cooling protective sleeve is guard electrode column bottom device, and itself and high-temp. furnace material, furnace gas are completely cut off, and ensures the normal work of electrode column.
The water-cooling protective sleeve water-cooled cavity of prior art design is for being longitudinally welded, and under hot environment, weld seam is easy to crack, and cooling water leaks out in stove, and moment produces a large amount of gas, blasts, and causes production accident; Cooling water longitudinally circulates, and back and forth circulates in high-temperature region and low-temperature space, and cooling effect is poor.
Utility model content
The purpose of this utility model is: provide one to overcome the shortcomings such as existing electrode water-cooling protective sleeve is easy to crack, cooling effect is poor, electric leakage sparking, and the electrodes in mine hot stove water-cooling protective sleeve of lower processing cost.
In order to achieve the above object, the technical scheme adopting is: electrodes in mine hot stove water-cooling protective sleeve, and it comprises outer sleeve body, flanged plate, water annulus, vertical water channel, water pipe, fire-proof asbestos rubber tube He Ge road; Described outer sleeve body one end is provided with flanged plate; Described water annulus is the annular cooling water pipeline that is welded on outer sleeve body inwall, in the middle of adjacent water annulus, separated by dividing plate, each dividing plate is equipped with breach, this breach is unique connectivity part of adjacent annular water channel, breach in adjacent separator staggers 180 °, between water annulus and flanged plate, is provided with every road; Described vertical water channel is two the adjacent vertical cooling water pipelines that are welded on outer sleeve body inwall, and vertically water channel is through flanged plate, every road and water annulus, and is communicated with apart from a flanged plate ring farthest with water annulus; Described water pipe is four, and water pipe is all through flanged plate He Ge road, and wherein two are communicated with water annulus, and another two are communicated with vertical water channel, and the other end of water pipe is all connected with fire-proof asbestos rubber tube.
Adopt the beneficial effect of technique scheme to be: the main cooling water channel of this electrodes in mine hot stove water-cooling protective sleeve is annular array, the temperature difference of its weld seam gradually changes, strengthen the fastness of welding, its annular design, ensure to have reduced bonding area under maximum film-cooled heat as far as possible, has reduced processing cost; Two-way cyclic water channel has increased the flow of cooling water, has ensured cooling effect.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model electrodes in mine hot stove water-cooling protective sleeve.
In figure, 1-outer sleeve body, 2-flanged plate, 3-water annulus, the vertical water channel of 4-, 5-water pipe, 6-fire-proof asbestos rubber tube, 7-Ge road.
Embodiment
Below in conjunction with drawings and Examples, the utility model is explained.
A kind of electrodes in mine hot stove water-cooling protective sleeve, it comprises outer sleeve body 1, flanged plate 2, water annulus 3, vertical water channel 4, water pipe 5, fire-proof asbestos rubber tube 6 He Ge roads 7; Described outer sleeve body 1 one end is provided with flanged plate 2; Described water annulus 3 is the annular cooling water pipelines that are welded on outer sleeve body 1 inwall, in the middle of adjacent water annulus 3, separated by dividing plate, each dividing plate is equipped with breach, this breach is unique connectivity part of adjacent annular water channel 3, breach in adjacent separator staggers 180 °, between water annulus 3 and flanged plate 2, is provided with every road 7; Described vertical water channel 4 is two the adjacent vertical cooling water pipelines that are welded on outer sleeve body 1 inwall, and vertically water channel 4 is through flanged plate 2, every road 7 and water annulus 3, and is communicated with apart from flanged plate 2 ring farthest with water annulus 3; Described water pipe 5 is four, and water pipe 5 is all through flanged plate 2 He Ge roads 7, and wherein two are communicated with water annulus 3, and another two are communicated with vertical water channel 4, and the other end of water pipe 5 is all connected with fire-proof asbestos rubber tube 6.
Cooling water enters vertical water channel 4 from fire-proof asbestos rubber tube 6 and water pipe 5, more moving by circulation from the water annulus 3 of outer sleeve body 1 opposite side, after water annulus 3 is run through, discharges again; The temperature difference of water annulus 3 gradually changes, and makes weld seam be difficult for splitting, and has strengthened fail safe and the cooling effect of water-cooling protective sleeve, and flanged plate 2 is installation positions of water-cooling protective sleeve, when installation, insulating barrier is padded on to flanged plate 2 upper and lower, locking; The contact site of water-cooling protective sleeve and body of heater all insulate, and ensures that not having electric spark produces the potential safety hazard causing.
