Intelligent mixing device and mixing method thereof

Abstract

The invention discloses an intelligent mixing device. The intelligent blending device comprises a pellet material blending system (A), an intelligent mixing system (C) and a material conveying belt (B) mounted between the blending system (A) and the intelligent mixing system (C), and is characterized in that the intelligent mixing system (C) comprises a mixing degree detecting instrument (namely,a pellet material mixing degree detector) (C1), a strong mixing control cabinet (C2) and a powerful mixing machine (C3); the mixing degree detecting instrument (C1) is arranged to a position near an outlet of the powerful mixing machine (C3); the mixing degree detecting instrument (C1) is electrically connected with the strong mixing control cabinet (C2); the strong mixing control cabinet (C2) iselectrically connected with the powerful mixing machine (C3); the strong mixing control cabinet (C2) is electrically connected with the blending system (A). The intelligent mixing device can detect the mixing degree indexes in real time and feed back the indexes to a powerful mixing machine control system and the blending system, so as to realize interlocking control, is based on the premise of guaranteeing the fresh pellet quality, reduces energy, equipment and bentonite consumption, and reduces the production cost.

Description

technical field [0001] The invention relates to a pellet production process in iron and steel smelting, in particular to an intelligent mixing device and a mixing method for pellet raw materials. Background technique [0002] In recent years, with the depletion of high-quality lump ore, fine ore and ultrafine fine ore have become the main raw materials for ironmaking. Due to the advantages of the pelletizing process in fine ore and ultrafine fine ore agglomeration, the pelletizing process has developed rapidly in recent years. development and maintained a good momentum of development. [0003] The mixing process is the core technical link of the pelletizing process and the core factor affecting the technical and economic indicators of the pelletizing process. The raw material of the pellets is mainly iron concentrate, which needs to be made into small balls of 8 mm to 16 mm before being roasted in the kiln. Since the concentrate powder itself has no cohesive force, it cann...

AI Technical Summary

Problems solved by technology

[0006] The amount of bentonite added is mainly determined by the quality of the green balls. The quality of the green balls is evaluated by the two indicators of drop strength and compressive strength. When the index is lower than the acceptance standard, it is unqualified green balls, but it is not necessary if the index is too much higher than the acceptance standard. Does not help production, but consumes more energy, equipment and bentonite, pure waste
