Abstract

A visual monitoring device for a flotation froth image is used in the beneficiation process monitoring and the optimization control field. The monitoring device consists of a high-resolution industrial camera, a high-frequency light resource and hardware equipment like a computer. By debugging and installing various hardware equipment, particularly installing a double protective cover, the device reaches IP65 protection class and meets the requirements of acquiring a high-quality froth image and real-time processing in the respect of the device performances. The image acquisition method is as follows: the industrial camera acquires an image of a flotation tank froth layer; video signals are digitized, and digital video signals are generated and transmitted to an image conversion card by an optical fiber interface and an optical fiber. The image conversion card converts the protocol data of the camera into the digital signals which are suitable for computer processing and reads the data to a memory of the computer by a hardware driver interface, and an image processing and application program reads, analyzes and processes the froth image.

Description

[technical field] [0001] The invention relates to a flotation foam image visual monitoring device, in particular to a flotation foam image visual monitoring device with high precision and high protection level, which is used in the field of mineral processing process monitoring and optimization control. [Background technique] [0002] Flotation is the most widely used beneficiation method in mineral processing. Mineralization and foaming are necessary in the process, which involves extremely complex physical and chemical reaction processes. Flotation foam is a three-dimensional complex body composed of gas-solid-liquid three-phase, which contains visual information such as bubble size, color, speed, etc., and flotation status and indicators. For many years, the dressing plant has mainly relied on the production workers to observe the foam to adjust the operation, but the state of the foam is random, and there is no uniform and quantitative standard for the judgment of the fo...
