Problems solved by technology
[0004] The general practice of each sintering plant is to use the original moisture of each raw material to calculate the raw material moisture through proportioning. Due to the uneven distribution of moisture in the raw material bin and the change of moisture in the new material, the calculated value of the moisture content of the batch is not real-time and accurate.

Abstract
A moisture detection and analysis device for sintered batch materials and an analysis method thereof belong to the field of measurement and control technology in the metallurgical industry. Device: Each probe of the moisture meter is set above the belt conveyor through a bracket, the speed sensor is set on the belt conveyor, the flow meter probe and control valve are set on the pipeline of the water supply system; the speed sensor, flow meter, control valve and moisture meter are respectively connected with the The central controller is connected, and the central controller is connected to the factory-level control system. Analysis method: Step 1: Set the preset parameters; Step 2: Determine the material running time from each blanking point to the batching outlet; Step 3: Determine the dry material content and moisture content of each layer of material at each time; Step 4: Determine the The real-time dry material content and moisture content of each layer of materials at the batching outlet; Step 5: Obtain the real-time batch material moisture at the batching outlet; Step 6: Send the real-time batch moisture content at the batching outlet to the factory level after a delay of time T Control system, as a real-time moisture content of the batch before mixing.
Description
technical field [0001] The invention belongs to the technical field of metallurgical industry measurement and control, and in particular relates to a moisture detection and analysis device for sintering batch materials and an analysis method thereof. Background technique [0002] The water content of the sintering batch plays a guiding role in the feed-forward regulation of the sintering supplementary water control. Since there are many types of sintering batch materials, the moisture content of each material is also different, and the material is distributed layer by layer on the belt conveyor through the feeding device; the ordinary moisture meter can only measure the surface moisture of the material, and can only detect the final distribution on the belt conveyor. Material moisture, and the penetrating moisture meter such as neutron moisture meter, its principle leads to the measurement result is "full water" composed of material moisture and crystal water, which cannot b...
