Embodiment 1

[0097] The sorting system 5 sorting method that the embodiment of the present invention provides is as follows:

[0098] (1) Feed material recovery: The selected material under pressure enters the flotation column directly through the feed distribution box or through the self-priming microbubble generator, and the easily floating material is mineralized in the column and floats to buoyancy. The upper part of the selection column is collected by the foam trapping device for recovery, and then the concentrate product is discharged, and the remaining materials go down in the column.

[0099] (2) Reverse collision mineralization recovery of the flotation column: the remaining material is mineralized with the floating air bubbles during the downward process in the column, and the particles with good buoyancy adhere to the air bubbles to form mineralized bubbles, and the mineralized bubbles float up to The upper part of the column is captured by the foam trapping device and recovere...

Embodiment 2

[0102] The video enhancement system 9 enhancement method provided by the embodiment of the present invention is as follows:

[0103] 1) Obtain the resolution of the flotation video to be displayed.

[0104] 2) Acquire the video enhancement method corresponding to the resolution of the flotation video to be displayed according to the corresponding relationship between different resolutions and flotation video enhancement methods.

[0105] 3) Perform enhancement processing on the flotation video to be displayed by using the flotation video enhancement method.

[0106] According to the corresponding relationship between different resolutions and flotation video enhancement methods provided by the present invention, the flotation video enhancement method corresponding to the resolution of the flotation video to be displayed is obtained, including:

[0107] If the resolution is the first resolution, acquire a noise reduction method for the flotation video to be displayed as a flotat...

Embodiment 3

[0112] According to the corresponding relationship between different resolutions and flotation video enhancement methods provided by the present invention, obtaining the flotation video enhancement method corresponding to the resolution of the flotation video to be displayed includes:

[0113] It is judged whether the resolution is smaller than a preset resolution.

[0114] If yes, acquire the method for reducing noise of the flotation video to be displayed as the flotation video enhancement method.

[0115] If not, acquire a method of performing contrast enhancement and saturation enhancement on the flotation video to be displayed as a flotation video enhancement method.

[0116] The enhancement processing of the flotation video data corresponding to the flotation video to be displayed through the flotation video enhancement method provided by the present invention includes: reducing noise on the flotation video to be displayed Flotation video for enhancement processing.

Abstract

The invention belongs to the technical field of magnetic flotation columns, and discloses a magnetic flotation column with an adjustable coil height and a forced ore discharge device and a control method thereof. The control system of the magnetic flotation column with the adjustable coil height and the forced ore discharge device comprises a video monitoring system, a main control system, an inflation system, a microbubble generation system, a separation system, a recovery system, a flushing system, a coil adjustment system, a video enhancement system and a display system. The number and thequality of flotation are guaranteed by the separation system and the height of the flotation column is reduced; meanwhile, different flotation video enhancement modes are obtained through the video enhancement system according to different flotation video resolutions so taht flotation video enhancement of different modes is carried out on the flotation videos with different resolutions, flotationvideo enhancement processing is enabled to better meet the characteristics of the flotation videos, a better flotation video enhancement effect is obtained and the ultra-definition visual effect of flotation video display is achieved.

Description

technical field [0001] The invention belongs to the technical field of magnetic flotation columns, and in particular relates to a magnetic flotation column with an adjustable coil height and a forced ore discharge device and a control method. Background technique [0002] The flotation column is an inflatable flotation machine that inflates and stirs the pulp through compressed air through a porous medium (aerator). There are microbubble countercurrent flotation columns and microbubble jet flotation columns. The cross section of the plate flotation column is round, square or round above and below. The ore slurry is fed from the upper feeding pipe and evenly flows into the flotation column. Compressed air is charged into the column through the air-filled chamber at the lower end of the column through the vertical air pipe. A large number of fine air bubbles formed are evenly distributed on the entire section, the slurry slowly descends under the action of gravity, and the a...
