Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, described a kind of steel slag hot with explosion trap boils in a covered pot over a slow fire device, comprise: slag stewing hole 1, and bore is in the tubaeform slag stewing lid 2 from top to bottom increased gradually, the heavy caliber inlet end of tubaeform slag stewing lid 2 cheats 1 top by water seal mechanism sealing cover in slag stewing, and the small-bore outlet side of tubaeform slag stewing lid 2 is connected with steam-pipe 3, steam-pipe 3 is provided with explosion trap 4, the structure of described explosion trap 4 is: comprise the tubular valve body 5 be connected with steam-pipe 3, tubular valve body 5 is hinged with the cover plate 6 that can cover tubular valve body 5 upper orifice downwards, at the pin jointed end place of cover plate 6, limited block 7 is installed, when cover plate 6 upwards overturns, the limited block 7 at cover plate 6 pin jointed end place is just in time against on the outer side wall of tubular valve body 5, in the present embodiment, be provided with a root rubber sealed strip 8 at the upper orifice edge of tubular valve body 5, when cover plate 6 covers tubular valve body 5 upper orifice downwards, cover plate 6 is just in time pressed on rubber weather strip 8, can improve the stopping property of explosion trap 4 so further, in the present embodiment, the structure of described water seal mechanism is: slag stewing hole 1 is provided with the aqua storage tank 10 that a circle has water 9, in aqua storage tank 10, interval is provided with some cushion blocks 11 be immersed in water 9, a circle bulge loop 12 is integrally extended with downwards at the edge of tubaeform slag stewing lid 2 heavy caliber inlet end, when tubaeform slag stewing lid 2 cover downwards slag stewing cheat 1 time, the bulge loop 12 of tubaeform slag stewing lid 2 is just in time against on the cushion block 11 in aqua storage tank 10 downwards, this water seal mechanism can not only substantially increase tubaeform slag stewing lid 2 and slag stewing and cheat stopping property between 1, prevent high-temperature steam cheat 1 from tubaeform slag stewing lid 2 and slag stewing between the outside loss in gap and scald workman, and structure is simple, easy for installation, and cost is lower double, in the present embodiment, be also respectively arranged with water eliminator 13 in three sides in slag stewing hole 1, can prevent the water in slag stewing process in aqua storage tank 18 from splashing out and scald workman like this, eliminate potential safety hazard, in the present embodiment, slag stewing hole 1 is also arranged and can cheat to slag stewing the nitrogen purging mechanism 14 purging nitrogen in 1, steel slag hot can not only be boiled in a covered pot over a slow fire the steam containing flammable explosive gas such as a large amount of hydrogen produced in process like this to blow away from slag stewing hole 1, prevent the flammable explosive gas such as hydrogen from cheating enrichment in 1 in slag stewing and quick-fried hole occurs, and due to nitrogen be rare gas element, prevent the generation of quick-fried hole phenomenon further, substantially increase safety in utilization,
Principle of work of the present utility model is as follows:
Slag in slag stewing hole 1 is being fetched water in efflorescence process of cooling, a large amount of steam containing flammable explosive gas such as hydrogen that can produce, these contain the flammable explosive gas such as hydrogen steam can together directly on enter steam-pipe 3 from the small-bore outlet side of tubaeform slag stewing lid 2 upper end, discharge through steam-pipe 3 again, when the instantaneous increase of the pressure in steam-pipe 3, some vapor can from the direct exhaust vapour pipeline 3 of tubular valve body upper orifice of explosion trap 4, avoid causing damage to steam-pipe, simultaneously by the design of cover plate pin jointed end place limited block 7, cover plate 6 excessive outwards upset because the outside impulse force of steam of directly discharging from tubular valve body upper orifice is excessive can be avoided, further increase the operation stability of equipment, in the process of steam to the small-bore outlet side movement of tubaeform slag stewing lid 2 upper end, some vapor can diffuse to the aqua storage tank 10 around slag stewing hole 1, this some vapor diffusing to aqua storage tank 10 can be absorbed by the water 9 in aqua storage tank 10, thus avoids high-temperature steam to scald workman to slag stewing hole 1 outer loss, cheat that internal pressure is instantaneous higherly causes water 9 in aqua storage tank 10 outwards to splash when steel slag hot is boiled in a covered pot over a slow fire in process, the water outwards splashed can be blocked by water eliminator 13, avoids water to splash out and scald workman, make nitrogen purging mechanism 14 purge nitrogen in slag stewing hole 1 simultaneously, be purged into the nitrogen in slag stewing hole 1, the steam containing flammable explosive gas such as hydrogen can not only be made successfully to cheat 1 from discharge slag stewing together, and due to nitrogen be rare gas element, prevent slag stewing to cheat 1 further and the probability in quick-fried hole occur.The utility model has energy good seal performance, can effectively prevent from, during slag stewing, quick-fried hole phenomenon, advantage safe to use occur.
