Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sintering equipment, and in particular relates to a grate plate forced resetting device for a chain grate machine. Background Art
[0002] In the chain-return-globe ball process, the chain grate is one of the three main machines. The raw balls are evenly arranged on the grate plate of the chain grate. After the process of blowing, drying and preheating, they enter the rotary kiln. The grate plate of the chain grate is fixed on the grate bed by a pin shaft. Due to the deformation of the grate plate or the loosening of the fixing pile, the grate plate will be abnormally positioned or stuck relative to the grate bed, resulting in the grate plate being unable to reset after returning to the lower return stroke and being flat on the grate bed, causing the grate bed to have hollow areas and cause different degrees of ball leakage. The ball leakage problem will seriously affect the efficiency of the production line. When the ball leakage reaches a certain level, it will directly threaten the production of the production line due to the excessive circulation of the production line. The existing chain grate grate plate reset device is mostly a heavy roller, which applies the gravity of the heavy roller to the grate plate to force the grate plate to reset. This method will cause serious wear on the surface of the grate plate, which not only affects its normal service life, but also requires manual care of the grate plate, wasting manpower.
