Abstract

The invention provides an accurate adjusting instrument for a bore diameter of a flue grate brick. The accurate adjusting instrument comprises an adjusting rod, a rotating shaft, a small flue, a grate brick, an upper adjusting steel plate, a bore, an adjusting sheet, a lower adjusting steel plate, a stop block, a sliding groove, a slider and a middle element, wherein the grate brick is arranged above the small flue, the rotating shaft is arranged in the small flue, the two ends of the rotating shaft are movably connected with the upper adjusting steel plate and the lower adjusting steel plate, respectively, one end of the middle element is movably connected with the adjusting rod through a pin, a scale is marked on one end of the outer side of the adjusting rod, and the adjusting rod is arranged in the wall bore of the small flue and capable of sliding freely in the wall bore. The accurate adjusting instrument is simple in structure, convenient to operate, and also accurate in adjustment, and convenient and practical.

Description

technical field [0001] The invention relates to the field of aperture adjustment of coke oven flue grate bricks, in particular to an instrument for precisely adjusting the aperture of the flue grate bricks. Background technique [0002] At present, domestic and foreign stamped coke oven briquettes are easily collapsed after being loaded into the carbonization chamber, which is one of the difficult problems in the production of stamped coke ovens. Combined with the actual production experience, it shows that the briquettes at the burner head on the side of the machine coke are the most likely to collapse. Observe the collapse of the briquettes through the smoke elimination hole. The collapse degree is about 1 to 2 meters. Coal directly affects the temperature of the furnace head, usually the first to fourth vertical channels of the furnace head, resulting in an increase in the temperature of the furnace head and deterioration of coke quality. The service life of the coke ove...
