Description

Technical Field

[0001] The utility model relates to the technical field of plastic detection of coking coal, and particularly relates to a device for measuring the plasticity of coal. Background Technique

[0002] Coking coal is a kind of bituminous coal. It is customary to collectively refer to the raw coal with certain caking properties that can coke under the coking conditions of a chamber coke oven and is used to produce coke of a certain quality as coking coal. The Gieseler fluidity index of coking coal can simultaneously characterize the quality and quantity of the plastic mass generated during the carbonization of coking coal. It is a comprehensive index and has an obvious correlation with other plasticity indexes. The Gieseler fluidity indexes of coking coals with different degrees of metamorphism have their own characteristics. Within a certain range, the coal type can be more accurately identified by relying on the Gieseler fluidity index, which has the advantages of high automation, time saving, and accurate data. However, in the actual working process, the existing detection devices often cause the stirring paddle to be "jammed" or the speed to slow down, resulting in a lower fluidity result, thus leading to inaccurate detection results. Therefore, we propose a device for measuring the plasticity of coal. Content of the Utility Model
