AI Technical Summary

Technical Problem

The existing heavy medium shallow tank separation process involves complex adjustment of suspension density, which is difficult to control effectively and prone to accidents such as heavy medium blooming and vortex formation, affecting the separation effect and safety.

Method used

The system employs a heavy medium shallow tank intelligent control system, which combines AI visual analysis technology and machine learning algorithms to monitor and adjust the opening of the solenoid valves for horizontal and upward flow in real time. It achieves precise sorting through fluid force field control, avoiding flooding and vortex phenomena.

Benefits of technology

It improves the stability and accuracy of heavy medium shallow trough separation, reduces the coal content in gangue, increases clean coal production, reduces manual intervention, adapts to changes in coal quality and fluctuations in operating conditions, and achieves efficient production control.

Abstract

This invention provides an intelligent control method for heavy medium shallow tank sorting, comprising: acquiring and preprocessing images of heavy medium shallow tank sorting based on AI visual analysis technology to determine whether any abnormal phenomena exist; extracting features related to the abnormal phenomena from the preprocessed images; training the extracted features based on machine learning algorithms to establish a sorting identification and control model; acquiring images of heavy medium shallow tank sorting in real time and using the sorting identification and control model to identify whether any abnormal phenomena exist, their degree, location, and scope of influence; and adjusting the opening of the horizontal flow high-precision solenoid valve and the upward flow high-precision solenoid valve when abnormal phenomena are found. This invention can effectively improve the stability and accuracy of the heavy medium shallow tank washing process, adapt to changes in coal quality and operating conditions in industrial settings, guide actual production control, and significantly improve the intelligence level of coal preparation plants.
