And the situation that the burner structure or the burner hole is easily damaged when a tool is manually used for cleaning is avoided, maintenance and replacement in production are avoided, and the production risk is greatly reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of refractory materials for a Kifset furnace in pyrometallurgical lead smelting, in particular to a burner structure for a Kifset furnace. Background Art

[0002] The Kifset furnace is divided into four main parts: reaction tower, molten pool, electric heating zone and ascending flue, which are arranged on the same fixed furnace bed. The reaction tower and the electric heating zone are separated by a partition wall to form a common rectangular molten pool, and the outer wall is composed of a copper water jacket. Burner structures of the same size are set at different positions on the reaction tower and the side wall of the electric heating zone on the upper part of the copper water jacket. The burner structure includes a burner structure body 1 and a burner hole 2 opened on the burner structure body 1. When a new Kifset furnace is opened to heat up or the furnace is stopped for insulation during production, the natural gas burner can be inserted into the furnace through the burner hole on the burner structure to perform the above operations. It is also used for temperature measurement, sampling, and observation of the furnace situation through this hole during the actual production process of the Kifset furnace.

[0003] In the actual production process, due to factors such as improper process control or poor charge reaction, the burner hole is easily slowly blocked or even completely blocked by the sticky slag in the furnace. At this time, it is necessary to manually operate a pneumatic pick to clean and dredge it. However, since the burner structure is made of one-piece magnesium-chromium refractory bricks with burner holes processed, the material strength is limited. The vibration of the pneumatic pick or improper operation can easily crack and damage the burner structure or cause cracks inside the burner hole. At this time, the safety risk of being forced to replace it during production is relatively high. Utility Model Content

[0004] The utility model develops a burner structure of a Kifuset furnace, which has a metal shell on the outside and is poured with high-temperature resistant castable inside. The manufactured burner structure has the characteristics of high temperature resistance and not easy to be damaged, which solves the problem that after the burner hole is blocked by sticky slag in the actual production process, the burner structure or the burner hole is easily damaged when manually cleaning with tools, avoids maintenance and replacement during production, and greatly reduces production risks.

[0005] A burner structure of a Kifusite furnace, comprising a metal shell 3, a burner structure body 1 inside the metal shell 3, and a through burner hole 2 provided on the burner structure body 1.

[0006] Furthermore, the burner structure body 1 is made of high temperature resistant castable material.

[0007] Advantages of the utility model:

[0008] 1. The utility model can not only withstand the erosion of high temperature of 1300℃, but also withstand the vibration and impact of pneumatic pick without damage, thus reducing the cost of repairing and replacing the burner structure;

[0009] 2. Since there is no need to replace the burner structure during the production process of the Kifuset furnace, the replacement operation in a high temperature environment is avoided, greatly reducing the safety risk. BRIEF DESCRIPTION OF THE DRAWINGS
