Online detection method for granulation effect of cylinder mixer

Abstract

The invention discloses an online detection method for the granulation effect of a cylinder mixer. The method comprises the following steps: calculating the feeding speed of a sintering raw material; the method comprises the following steps: calculating and adjusting the angle of a blanking surface of an inclination-angle-adjustable multi-stage screening channel at a discharge port of a cylinder mixer, collecting weight data of undersize materials of each stage of screening channel, and uploading the weight data to an online detection server; and the online detection server calculates the granulation effect of the mixing machine according to the channel grading condition, the sieve pore diameter and the undersize material weight. By arranging an inlet feeding speed detector, an adjustable inclination angle type multi-stage screening channel and a weighing sensor for different grades of screen underflow, on-line detection and analysis of the material granularity at the outlet of the cylinder mixer are realized, and evaluation indexes are formulated to quantitatively evaluate the granulation effect; the online detection on the granulation effect of the mixing machine is realized.

Description

Technical field: [0001] The invention relates to a detection device and a detection method for an online detection method of the granulation effect of a cylinder mixer. Background technique: [0002] Iron ore sintering is an important link in the modern iron and steel metallurgical process. Its main production link is to ignite and burn evenly mixed small granular raw materials on a trolley-type sintering machine to fuse them into massive sinter. In order to ensure the strength and chemical composition of sinter agglomerates, the raw materials need to be fully burned on the sintering machine. Various raw materials produced by sintering must be uniformly mixed, granular, and moderately humid before entering the sintering machine. Among them, uniform mixing is to ensure the consistency of the chemical composition of the material; granularity is to ensure sufficient air permeability during combustion, increase the outer surface of the material, and improve the consistency of c...

AI Technical Summary

Problems solved by technology

In the traditional mixing and granulation production process, the barrel length of the cylinder mixer is fixed, the transmission device is driven by a high-voltage motor with power frequency, and the inclination angle of the installation support is also fixed, so there is no effective means to control the mixing and granulation process

At the same time, the granulation effect of the mixer cannot be measured and described by simple physical quantities, so the production of the cylinder mixer can only be monitored by manual observation, and cannot be automatically quantitatively detected on-line

The unmeasurable and uncontrollable state of the mixed production process of sintering raw materials makes it difficult to realize the precise process control of the process. The quality of the mixture preparation in the iron ore sintering process cannot be guaranteed, and there will be local bulk or large sticky materials. It affects the normal operation of the subsequent production process of sintering, thereby reducing the quality stability of sintered ore products
