Practical training device for automatic control of medicine addition of multi-process floatation column separation system

Abstract

The invention provides a practical training device for automatic control of medicine addition of a multi-process floatation column separation system and belongs to the technical field of floatation. The device comprises a medicine tank, a dosing pump, a stirring bucket, ore feeding pumps, floatation columns, ore discharge valves, a transferring tank, a concentrate tank, a tailings pond, flow sensors, an expert control system, a computer, a light source, CCD (charge-coupled device) cameras, mechanical arms, screens, a washing water tube and a rack, wherein both the flotation columns and the stirring bucket, the transferring tank, the concentrate tank and the tailings pond and the medicine tank and the stirring bucket are connected through pipelines; the dosing pump and the ore feeding pumps are respectively arranged outside the medicine tank, the stirring bucket and the transferring tank; the ore discharge valves are arranged at bottoms of the flotation columns; the CCD cameras and the mechanical arms are arranged above the flotation columns; the screens are fixed at the lower parts of the mechanical arms; the flow sensors are arranged on pipelines for connecting the ore feeding pumps and the dosing pump; and the expert control system is used for acquiring data and image information. The device supports switching of multiple flotation processes, is simple in structure and easy to achieve, and can be developed for a second time.

Description

technical field [0001] The invention relates to the technical field of flotation, in particular to a multi-process flotation column sorting system medicament addition automatic control training device. Background technique [0002] At present, my country's information technology and traditional mineral processing technology continue to be deeply integrated. Mineral processing is a typical process industry. Realizing on-line detection and control of mineral processing is of great significance for reducing the work intensity of labor workers and improving production efficiency; flotation is a kind of One of the most widely used separation methods in mineral processing, the images of the foam layer and sieved foam products of the flotation column need to be observed manually on site, and it can be judged from the images of the foam layer and the sieved foam products that have been added Whether the dosage of the agent is appropriate, and further dosing, the dosage of the agent is...

AI Technical Summary

Problems solved by technology

In most of the flotation workshops in China, the flotation agents are added through the flotation operators to observe the flotation foam, and manually take samples for screening and analysis with eyes, and judge whether the flotation agents are "deficient" or excessive according to years of accumulated experience. Then manually adjust the amount of reagent additives. Manual flotation reagent addition is labor-intensive, the control level varies from person to person, the accuracy is poor, the stability is poor, and the effect is difficult to estimate; due to the variety of mineral samples and the complicated flotation process, manual control The experience of reagent addition is poorly reproducible for different ore samples and different processes, and in the research process of the automatic control system of flotation reagent addition, according to different ore samples and processes, it is necessary to go to different flotation production sites to establish experts in foam state identification Knowledge base, time and economic cost are high. Even if the flotation system is built in the laboratory, its typicality, applicability and portability are poor. In the current teaching of mineral processing engineering, there is no corresponding demonstration and training The device, in general, lacks a typical systematic research and teaching demonstration and training device for the detection and control of mineral processing processes
