The invention discloses a moisture content measuring device. The device is used for measuring moisture of a sintered ore in a sintering process, and comprises a material collecting system, a pressure system, a material receiving plate, an image detection system, a model training system and a control system; the material collecting system is arranged at a feeding hole of the pressure system and is used for collecting a material as a sample; the pressure system extrudes the sample; the material receiving plate is arranged below a discharge hole of the pressure system and is used for receiving the sample; the image detection system is arranged at the material receiving plate and is used for acquiring an image of the sample and analyzing image characteristics; the model training system is used for receiving data from the image detection system, training a convolutional neural network model and outputting the moisture content of the sample through the trained convolutional neural network model; and the control system is used for controlling operation of the material collecting system and the pressure system. The invention also provides a moisture content detection method. The device and method can rapidly detect the moisture content of the sintered ore, and are simple in structure and high in precision.
Description
technical field [0001] The invention relates to the field of iron and steel production, in particular to a moisture content measurement device and a detection method. Background technique [0002] In the iron and steel industry, the moisture content of sinter has an important impact on the final product quality and economic benefits of sinter. The level of moisture content will not only affect the permeability of sintered ore, but also directly affect the sintering process, such as the influence on the over-burning and under-burning state of sintering ore. Quality affects, such as drum strength, FeO content, etc. [0003] At present, drying weighing detection method, infrared moisture meter detection method and neutron measurement method are commonly used in determining the moisture content of sintered ore. The drying weighing method is a general method for measuring the moisture content of powder materials. The percentage of the original weight is used as the water conte...
