Abstract

The invention discloses a feed inlet with an improved structure on a smelting furnace. The feed inlet comprises a feed pipe. A water tank cavity is formed in the lower end of the feed pipe. A water injection hole communicated with the water tank cavity is formed in the outer wall at the lower end of the feed pipe. A vertical annular cavity groove is formed in the portion, at the upper side of thewater tank cavity, in the feed pipe. Annular cut grooves are formed in the upper and lower bottom surfaces of the annular cavity groove. A first vent hole and a second vent hole penetrating through the outer wall of the feed pipe are correspondingly formed in portions, at the upper and lower ends of the annular cavity groove, of the side walls of the cut grooves. An annular boss is formed on the portion, between the first vent hole and the second vent hole, of the outer wall of the feed pipe. A circular rotating disc is inserted into the annular boss. A sector-shaped stopper is formed on the end surface of the inner side of the rotating disc. The stopper abuts against the inner side bottom face of the annular boss. The outer wall of the stopper abuts against the inner wall of the annular boss. By the adoption of the feed inlet, a charging material at a charging port of a metallurgical furnace can be cleaned conveniently, and the coking condition is reduced.

Description

Technical field:

[0001] The invention relates to the technical field of smelting furnaces, in particular to a structure-improved feed port on the smelting furnace. Background technique:

[0002] Metallurgy furnace is a commonly used metallurgical industrial equipment. When feeding into the metallurgy furnace, the furnace material will stick to the inlet of the metallurgy furnace and coke. The existing coking problem in the inlet of the metallurgical furnace is generally manually stabbed. The required labor intensity is relatively large and there are many people. If the furnace charge contains substances that are difficult to clean, once it sticks to the charging port, it will not help even manual poking. In addition, sometimes a large amount of smoke will be emitted when the furnace charge is stuck on the charging port, which will endanger the health of personnel and cause personnel to operate the table. Unable to stay on for a long time. Invention content:
