Material online moisture detection device and detection method thereof

Abstract

A material online moisture detection device comprises a (cylindrical) rotating bin (1), multiple microwave generation devices (2) arranged at the upper part of a rotating bin top cover (101) and multiple weighing devices (3) arranged at the lower part of a rotating bin chassis (102); four chambers are formed in the rotating bin chassis (102); the rotating bin (1) has four stations which are a material feeding station (a), a primary drying station (b), a secondary drying station (c) and a material discharging station (d) in sequence in a clockwise direction, wherein the four chambers are switched between the positions of the four stations in circulation. The material online moisture detection device provided by the invention has the advantages that the four chambers and the four stations work in sequence in circulation so as to guarantee that the moisture detection device can continuously detect the moisture content of materials on line in real time.

Description

technical field [0001] The invention relates to a material moisture detection device and method, in particular to an on-line moisture detection device for bulk materials and a detection method thereof, and belongs to the technical field of raw material property detection in the production process of sintered pellets in the metallurgical industry. Background technique [0002] In the field of metallurgical sintering and pelletizing, a certain amount of moisture is generally required in the process of mixing materials to provide the necessary cohesiveness and adhesion for the formation of material pellets. This moisture includes a part of the moisture contained in the mineral material itself, and moisture will also be added during the mixing process, so that various raw materials can be mixed evenly, which is convenient for the balling and granulation of the material, and is conducive to a more sufficient reaction in the subsequent process. If the amount of water is too low, t...

AI Technical Summary

Problems solved by technology

When the material conveyed on a belt is uncertain, it is difficult to realize automatic water measurement of different materials, and it is necessary to manually adjust the detection parameters of the moisture meter according to the change of the material on the belt. When the material changes frequently, it is difficult. Realize the online detection of moisture; the microwave method cannot accurately detect the moisture content in the core of the material

[0004] The detection equipment and theoretical solutions corresponding to the above methods are complicated, and sometimes professionals are required to solve them.
