The technical field is as follows:

the utility model relates to a metal smelting technical field especially relates to a novel feeding mouth device of hot stove in ore deposit.

Background art:

the hot stove in ore deposit unloading mouth is used for the hot stove in ore deposit smelting along cloth around the electrode, because the unloading mouth is located furnace, and operating temperature is high, consequently must install cooling device on the unloading mouth, and in prior art, cooling device generally is the spiral water pipe, and the outer wall of spiral water pipe suit at the unloading mouth, the cooling water flows from top to bottom during the use and reaches the cooling effect, but the following problem of ubiquitous in the in-service use process: 1. the spiral cooling water pipe has an excessively long flow path, so that the temperature of the cooling water pipe is sequentially increased from top to bottom, the cooling effect at the bottom of the cooling water pipe is poor, the bottom of the cooling water pipe is just the bottom of the blanking nozzle and is the highest temperature position, the bottom of the blanking nozzle is easy to burn through, and the cooling effect is to be further improved; 2. the spiral cooling water pipe is difficult to process and manufacture, has higher cost, wastes time and labor once damaged and repaired and replaced, and has high repair cost.

The utility model has the following contents:

an object of the utility model is to provide a novel feeding mouth device of hot stove in ore deposit.

The content of the utility model is as follows: a novel discharging nozzle device of a submerged arc furnace comprises a vertically arranged square inner cylinder, a plurality of inner cooling grooves with semicircular cross sections are vertically and downwards arranged on the outer wall of the square inner cylinder in an evenly distributed mode, sealing long grooves are vertically arranged between the adjacent inner cooling grooves in an adjacent mode, sealing strips are arranged in the sealing long grooves, outer guard plates are fixedly arranged on the four outer walls of the square inner cylinder through bolts, a plurality of outer cooling grooves with semicircular cross sections are evenly arranged on the inner side of the outer guard plates in an evenly distributed mode, the inner cooling grooves and the outer cooling grooves are buckled together to form a cooling vertical pipe, an upper concentrating ring and a lower concentrating ring are respectively and horizontally and fixedly arranged at the top end and the bottom end of the square inner cylinder, an upper cooling ring cavity is formed in the upper concentrating ring, the upper cooling ring cavity is communicated with the top end of the cooling vertical pipe, and a water outlet pipe is arranged on the outer wall of the upper concentrating ring, the water outlet pipe is communicated with the upper cooling ring cavity, a lower cooling ring cavity is formed in the lower concentration ring, the lower cooling ring cavity is communicated with the bottom end of the cooling vertical pipe, a water inlet pipe is installed on the outer wall of the lower concentration ring, and the water inlet pipe is communicated with the lower cooling ring cavity.

Furthermore, sealing rings are arranged at the communication position of the cooling vertical pipe and the upper cooling ring cavity and the communication position of the cooling vertical pipe and the lower cooling ring cavity.

The utility model has the advantages that: the spliced cooling structure has simple processing and manufacturing, low equipment manufacturing cost, quick and simple maintenance and replacement, trouble and labor saving; simultaneously the utility model discloses a cooling standpipe flow path is shorter, and the cooling effect is more even, and the flow direction of cooling water is for following supreme flow pattern down, can effectually guarantee that blanking nozzle bottom cooling effect is best, prevents that the bottom of blanking nozzle from being burnt, improves the life of blanking nozzle, is worth using widely on a large scale.
