Bottom outflow treating device applied to material water washing system and process method for treating bottom outflow by using bottom outflow treating device

Abstract

The invention provides a bottom outflow treating device applied to a material water washing system and also relates to a process method for treating a bottom outflow by using the bottom outflow treating device. The treating device (1) comprises a water tank (3) used for accommodating the bottom outflow, wherein a transmission machine (4) with a transmission function is arranged in the water tank (3) and extends to the exterior of the water tank (3) from the interior of the water tank (3); and an output pipe (5) used for outputting the bottom outflow is arranged at the bottom of the water tank (3). By the bottom outflow treating device applied to the material water washing system, and the process method for treating the bottom outflow by using the bottom outflow treating device, large granular mine powder in the bottom outflow can be separated out and are conveyed to the exterior of the water tank from the water tank. After the treating device continuously works for hours, no hardened material is formed at the bottom of the water tank, and no large granular mine powder is found at the bottom of the water tank. Therefore, the device and the method are feasible for continuously treating the bottom outflow.

Description

technical field [0001] The invention belongs to the technical field of material water elutriation system, more specifically, relates to an underflow treatment device applied to the material water elutriation system, and also relates to a process method for using the underflow treatment device to treat underflow. Background technique [0002] Blast furnace concentrate is the basis for strengthening smelting and improving economic and technical indicators. Blast furnace concentrates include measures such as improving the grade of iron-containing materials and reducing the powder content of incoming materials. Due to its high grade, the imported lump ore has played an important role in improving the grade of the furnace charge. But its texture is soft, and the powder content can rise to about 28% during the unlucky process. Although it has been screened before entering the furnace, due to the influence of its moisture, especially in the rainy season, the screening efficiency ...

AI Technical Summary

Problems solved by technology

However, the bottom flow of the material water elutriation system has coarse particle size, high specific gravity, poor fluidity, and easy hardening, which is not conducive to the industrial continuous conveying operation of the pump.

Coupled with the limitation of the raw material site, the space of the material water elutriation system is small, and the processing load is large, and the continuous operation time is long. It is necessary to carry out ore slurry treatment at the same time as the lump ore water elutriation, and the large-area sedimentation tank method is not suitable for space and time. Systematic slurry treatment
