Sintered ore FeO content on-line detection device and method with inclined sleeve structure

Abstract

The invention belongs to the technical field of on-line detection devices, and particularly relates to a sintered ore FeO content on-line detection device of an inclined sleeve structure and a method. The detection device is characterized by comprising an electric control system, a feeding and batching scale, a feeding inclined chute arranged below a blanking point of the feeding and batching scale, a magnetic induction coil and the framework of the magnetic induction coil which are connected to the outer wall of the middle of the material conveying inclined chute in a sleeving mode, a material level detection instrument which is arranged above the material conveying inclined chute, and a material flow detection instrument which is arranged below the material conveying inclined chute, wherein the material conveying inclined chute comprises a first chute body and a second chute body which is correspondingly connected with the first chute body in a buckled mode. The material blocking state can be automatically judged, meanwhile, feeding is stopped, and material stacking is avoided; and the material conveying inclined chute, the magnetic induction coil and the framework of the magnetic induction coil are installed in a lubricating mode through a sleeve structure, the material conveying inclined chute can be conveniently pulled out of and installed back into the magnetic induction coil and the framework of the magnetic induction coil, the material conveying inclined chute is of a detachable split structure, blocked materials in the material conveying inclined chute can be conveniently removed, and the labor intensity of maintenance personnel is reduced.

Description

technical field [0001] The invention belongs to the technical field of on-line detection devices, and in particular relates to an on-line detection device and method for FeO content of sintered ore with an inclined sleeve structure. Background technique [0002] In steel production, the finished product produced by sintering is called sinter, and sinter is the main raw material for blast furnace ironmaking. Among them, the content of FeO (ferrous oxide) in sinter is one of the quality indicators that ironmaking and sintering attach great importance to. Ironworkers also use the content of FeO in sinter to evaluate the quality of sinter, especially the strength and reduction performance of sinter. An important sign of good or bad. Under certain conditions, the content of FeO in sinter is closely related to its strength, and the content of FeO in sinter also has a great influence on the indirect reduction in the upper and middle parts of the blast furnace. More importantly, i...

Problems solved by technology

However, due to the measurement principle, the diameter of the magnetic induction coil cannot be too large, and there are inevitably large pieces of material in the sintered ore, which leads to the biggest problem encountered in the actual use process is material blocking

The result is that the maintenance of the measuring device is difficult, and the life of the magnetic induction coil and the skeleton is greatly reduced due to wear and tear, which ultimately affects the use effect of the entire device.
