Description

TECHNICAL FIELD

[0001] The present application relates to the field of metering device, in particular to a clinker metering chain plate type metering scale. BACKGROUND

[0002] In some cement, metallurgical and other industries, high-temperature clinker after rotary kiln calcination is cooled by grate cooler and other equipment, and then is transported to clinker storage by cableway, so as to calculate production capacity and adjust process. In domestic clinker calcination process, raw meal and coal powder entering the kiln are measured with high precision, but high-temperature clinker after exiting the kiln is not accurately measured before being transported into the storage, and there is no mature and reliable metering device for accurate measurement of clinker exiting the kiln. Accurate measurement of clinker exiting the kiln helps to improve the calcination process, accurately controls the loss on ignition of clinker, and improves the quality of clinker exiting the kiln. Some manufacturers use a rigid support rail weighing mechanism with four weighing sensors, but the mechanism can only obtain relatively accurate weighing results in a static state. The conveying assembly in dynamic variable speed operation generates a resultant force including rolling friction and deviation friction on the track, and the friction increases and causes wear when the track is covered with dust, which eventually leads to an unrealistic weight signal and large fluctuations, which is unacceptable for production capacity statistics.
