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

Embodiment 1

[0059] The online detection method of the present embodiment comprises:

[0060] The first step: the sintering raw material is transported to the entrance of the mixer through the feeding belt, and a weighing detection device and a speed detection device are installed at the feeding belt, and the feeding speed of the sintering raw material is obtained through weighing and belt speed measurement. The sintered raw materials are stirred and mixed in a cylinder mixer to form a granular mixture.

[0061] Step 2: The mixed material at the outlet of the cylinder mixer falls onto the belt conveyor at the outlet, and the belt conveyor at the outlet changes the running speed through the frequency converter to adjust the thickness of the material layer.

[0062] Step 3: According to the collection cycle, the camera collects the material surface image of the belt conveyor at the discharge outlet at a fixed point and time, and uploads it to the online detection server.

[0063] Step 4: Th...

Description

technical field [0001] The invention relates to an online detection method for 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 combustion; moderate humidity is mainly to impro...
