The invention relates to an online detection method and device for the moisture content of a belt conveyor material. First, the image acquisition device is used to collect images of the materials located at the initial position of the weighing section of the belt conveyor according to a preset frequency; secondly, when the Whether the sum of the material advance distances corresponding to the material image of the belt conveyor meets the length requirement of the weighing section of the belt conveyor, the control material weighing device collects the actual weight of the material on the weighing section of the belt conveyor, and, according to the material surface in the collected material image Calculate the dry basis weight of the material on the weighing section according to the corresponding pixel information and the calibrated dry basis density of the material; calculate the moisture content of the material according to the above actual weight and dry basis weight. The present invention uses the method of collecting material images to calculate its dry basis weight, and the actual mass of the material is directly measured by a contact weighing device, so the detection result of the present invention is not limited by the detection of the moisture content of the material surface area and is not easily affected. Interference from the external environment.
Description
technical field [0001] The invention relates to the technical field of on-line detection of materials, in particular to an on-line detection method and device for the moisture content of materials in belt conveyors. Background technique [0002] Belt conveyor, referred to as belt conveyor, as a material transportation device, has been widely used in various industries such as metallurgy, coal and chemical industry. For example, in sintering production, firstly, various materials with different components are sent to the mixer through a belt conveyor, then, according to the moisture content of each material, an appropriate amount of water is added to the mixer for mixing, and finally, The mixed materials are sent to the sintering machine for material sintering. Since the moisture content of the mixture during the sintering production process will directly affect the granulation effect of the sintering ore, the real-time collection and analysis of the moisture data in the mat...
