Description

The present invention relates to the field of bulk material handling technology. It is mainly a short-process ore mixing treatment method and system at the stage of raw material production in ore processing trade and steel metallurgy, which mixes and homogenizes different types of materials to make mixed ore that is homogeneous in terms of grain size and composition.

Steel metallurgy, which requires high precision in the composition and grain size of ore materials, has traditionally set up a second processing plant for blending and homogenization in addition to the first processing plant in the general raw material field, which allows different types of materials to be processed. Homogenization is the mainstream. As a process, after the materials arrive at the first processing plant, they are transported to a large-scale storage-type homogeneous blending tank by a feeding device at different times. Sent for homogenization. Although this conventional process can improve material homogeneity and quality consistency, the construction cost of compounding and homogenization plants is high, especially in the homogenization plant, which requires the installation of closed workshops and stacker clays. It is essential and cost is a challenge. Other problems include multiple shipments of materials, complex treatment processes, large amounts of equipment required, and high maintenance costs.

The problems to be solved by the present invention are the above-mentioned high construction costs, the large number of transportations of materials, the complexity of the treatment process, the large number of required facilities, the high maintenance costs, etc. To provide a mixed processing method and system.

The present invention, which is a short-process ore mixing method, uses a high-precision mixing method to take out different types of materials in the first processing plant at the same time based on a predetermined amount, merge, homogenize, and transfer. It realizes homogenization of mixed ore particle size and composition through transportation system including homogenization and cloth homogenization.

Confluence homogenization involves merging, dispersing, and concentrating materials at the confluence point of the materials taken out. More than one type of material is flowed together, and the secondary confluence homogenization is to flow two or more material flows that have passed through the first confluence homogenization.

Transfer homogenization is the agitation of the material stream that has undergone the secondary confluence homogenization.

Fabric homogenization is the layering of material streams that have undergone transfer homogenization.

When different types of materials are brought into the first treatment plant, they are transported to their respective positions on each line according to a predetermined proportion.

The present invention, which is also a short-process ore mixing processing system, consists of a material infeed line, a first processing plant, a stacker clay, and a material outflow line. The material delivery line has a structure in which a confluence homogenization section, a transfer homogenization section, and a cloth homogenization section are sequentially connected. A plurality of the stacker clays take out materials of different types at the same time based on a predetermined proportion, using a high-precision mixing method, and send them to a material delivery line. The merging and homogenizing portion performs merging, dispersing, and consolidating materials of different types at the merging point of the materials. The transfer homogenization section agitates the materials from the confluence homogenization section. The fabric homogenization station stacks the material stream from the transfer homogenization station.

The confluence homogenization part is divided into a first confluence homogenization part where two or more types of materials flow together and a second confluence homogenization part where two or more material flows that have undergone the first homogenization of the confluence flow. divided.

Said primary confluence homogenization section consists of a first funnel, a counter-attack loading plate and a first downstream belt conveyor. The second confluence homogenization part consists of a second funnel, a first material cone, a mixer, and a second downstream belt conveyor. Connected to the funnel, it contains a built-in counter-loading plate that serves to disperse the material flow. The second funnel contains a first distribution cone that functions to disperse the material flow from top to bottom and a material flow cross-sectional mixing device. And below the second funnel there is a second downstream belt conveyor. The vanes of the mixer are serrated or double hooked.

Said transfer homogenization section consists of a third funnel, a second dispensing cone, an agitator and a third downstream belt conveyor. The third funnel is connected to the second funnel through the second downstream belt conveyor, and inside there are the second distribution cone that has the function of dispersing the material flow and the agitator that agitates the material. There are three downstream belt conveyors. The blades of the agitator are helical.

The cloth homogenization part consists of a fourth funnel and a cloth wheel. The vertically long fourth funnel is connected to the third funnel through the third downstream belt conveyor, and is equipped with a cloth car that repeatedly reciprocates and stacks materials.

In the present invention, materials transported to the first treatment plant are mixed by controlling the amount of inflow and outflow, adding physical dispersion work, and finishing different types of materials into high quality mixed ore. , It eliminates the need to construct mixing equipment and homogenization treatment plants, shortens the work process, and reduces capital investment and maintenance costs.

The ore mixing process and system of the present invention is simple and practical, and can significantly shorten the production process over conventional ore mixing homogenous blending systems.

The present invention applies to the process of raw material production stage in ore processing trade and steel metallurgy field.
