Abstract

The invention relates to an annular furnace, in particular to an annular furnace oil seal structure, and belongs to the technical field of annular furnace seal structures. The annular furnace oil sealstructure comprises an oil seal frame of an annular structure. An inner overflow frame and an outer overflow frame are arranged on the inner ring and the outer ring of the oil seal frame correspondingly. An oil seal tank is arranged in the oil seal frame and is filled with seal oil. Seal knives are inserted in the seal oil of the seal tank. An inner overflow tank is arranged in the inner overflowframe. An outer overflow tank is arranged in the outer overflow frame. A cooling frame is welded to the bottom of the oil seal frame. A cooling tank is arranged in the cooling frame and is filled with a cooling medium. The annular furnace oil seal structure is simple, compact and reasonable in structure, leakage and contamination of the seal oil can be avoided, and the use environment of maintenance devices is safe; and the height of the oil seal tank can be regulated, and cleaning and maintaining are convenient.

Description

technical field

[0001] The invention relates to an annular furnace, in particular to an annular furnace oil seal structure, and belongs to the technical field of annular furnace sealing structures. Background technique

[0002] The diameter of the large annular heat treatment furnace is usually 10m to 17m, and the seal between the middle turntable and the inner and outer ring shells is sealed by inserting a sealing knife into the sealing oil. The furnace is heated to 1000°C for a long time, and the heat is transferred to the sealing oil through the sealing knife, and the sealing oil is cooled by water heat exchange. Affected by the change of furnace pressure in the furnace, there is a pressure difference between the furnace and the outside of the furnace, causing the sealing oil to be pressed out of the sealing groove, resulting in leakage and pollution. Restricted by the length of the furnace bottom sealing knife, it is not easy to clean the oil seal groove close to the fu...
