Abstract
The utility model relates to a water-cooled structure of a lid and a blanking nozzle of a submerged arc furnace, which comprises a lid and a blanking nozzle of a submerged arc furnace. The blanking nozzle is provided with a feeding port, the periphery of a blanking nozzle body is additionally provided with an isolating plate, thereby forming isolated space, and circulating cooling water flows in the space, thereby forming a water-cooled wall on the periphery of the blanking nozzle body. The end of the water-cooled wall is provided with a cooling water feeding and discharging pipe. Since the isolating plate is additionally arranged on the periphery of the blanking nozzle and circulating water flows for cooling, the utility model changes the working environment of the material nozzle, and reduces the temperature of the blanking nozzle to below 800 DEG C from original 600 DEG C, thereby prolonging the service life of the blanking nozzle to two years, and greatly reducing the production cost and the rate of parking for troubleshooting.
Description
Technical field
The utility model relates to the hot stove in ore deposit, the water-cooling structure of particularly a kind of ore deposit hot stove bell blanking mouth.
Background technology
Calcium carbide (ferroalloy, industrial silicon) ore deposit hot stove bell blanking mouth is in continuous operation under the hot environment for a long time, its main effect is to connect blanking system and burner hearth, the material piece is in blanking system quilting mouth imports the hot stove in ore deposit, its average speed reaches per hour 125 cubic metres, is last link in the material piece course of conveying.Because its environment temperature height, 600 ℃ of average out to instantaneously reach 800 ℃, and device damage is serious, will change once in average two months.
Therefore, be necessary to design a kind of ore deposit hot stove bell blanking mouth water-cooling structure, to improve the current working condition of the hot stove in ore deposit.
The utility model content
Task of the present utility model provides a kind of ore deposit hot stove bell blanking mouth water-cooling structure, it has solved above-mentioned existing in prior technology problem, by adding one deck division board in the blanking mouth periphery, connecing the recirculated water cooling, changed material mouth working environment, prolong service life, reduced production cost and trouble hunting parking rate.
Technical solution of the present utility model is as follows:
A kind of ore deposit hot stove bell blanking mouth water-cooling structure comprises hot stove bell in ore deposit and blanking mouth, and blanking mouth is provided with charging aperture, one deck division board is set up in described blanking mouth body periphery, form an insulating space, this space circulation recirculated cooling water is thus at the peripheral water-cooling wall that forms of blanking mouth body;
The end of described water-cooling wall is provided with the cooling water water inlet pipe and water outlet pipe.
Described division board is arranged on the below of blanking mouth charging aperture.
Ore deposit of the present utility model hot stove bell blanking mouth water-cooling structure is to add one deck division board in the blanking mouth periphery, connect recirculated water cooling, changed material mouth working environment, the blanking mouth body temperature is reduced to below 80 ℃ by original 600 ℃, can extend to 2 years service life, greatly reduces production cost and trouble hunting parking rate.

Reference numeral:
1 is the hot furnace charge pipe in ore deposit, and 2 is blanking mouth, the hot stove bell in 3 ore deposits, and 4 is charging aperture, and 5 is water-cooling wall, and 6 is the cooling water water inlet pipe and water outlet pipe.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to Fig. 1 to Fig. 6, a kind of ore deposit of the present utility model hot stove bell blanking mouth water-cooling structure is made up of hot stove bell 3 in ore deposit and blanking mouth 2, and blanking mouth 2 is provided with charging aperture 4, and charging aperture 4 is a weldment, as shown in fig. 1, the hot furnace charge pipe 1 in ore deposit inserts in the charging aperture 4 of blanking mouth 2.
Shown among Fig. 2 and Fig. 4 that blanking mouth 2 body peripheries have set up one deck division board, formed an insulating space, this space circulation recirculated cooling water is thus at the peripheral water-cooling wall 5 that forms of blanking mouth 2 bodies.In the end of water-cooling wall 5 cooling water water inlet pipe and water outlet pipe 6 is set, connects the recirculated water cooling.
Specifically, division board is the below that water-cooling wall 5 is arranged on blanking mouth charging aperture 4.Set up water-cooling wall 5, changed material mouth working environment, the blanking mouth body temperature is reduced to below 80 ℃ by original 600 ℃, prolonged service life, reduced the trouble hunting parking rate, also reduced production cost.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
