According to the on-line detection device, the difficulty that the flotation tailing ash cannot be directly measured is solved, and the shortcomings of large chemical check error, low instantaneity, high labor intensity and complex working procedures which are caused by artificial sampling, drying and sample making in the prior art are overcome; the adjustment time of controlling indexes of coal separation products is shortened; the using amount of floatation medicines of the coal preparation plant is reduced; the detection accuracy and the detection reliability are effectively improved.
Description
Technical field
The present invention relates to a kind of on-line measuring device that detects coal preparation plant's flotation tailing ash content, belong to colliery coal separation checkout equipment technical field.
Background technology
Ash content of coal is aphlogistic impurity part, and the ash content of coal size is an important indicator of Coal Quality.The work of coal preparation plant is exactly to produce to meet the coal that certain industry requires ash content.If the ash rate customer requirements height of the coal of producing, then this batch coal is defective; If even institute's producing coal charcoal ash rate customer requirements is low little by little, because institute's coal washing is in hundreds and thousands of ten thousand tons, wherein accounts for through the fine particle coal of floatation process and always go into about 20% of the amount of washing, accumulation gets up also will cause bigger economic loss and energy dissipation.Therefore rationally control floating product ash content is significant concerning coal preparation plant.
At present, the flotation tailing ash content of coal can't directly be measured, the coal separation process is artificial sample, the labour intensity of tailings ash content manual detection is big, operation is loaded down with trivial details, error is big, real-time is poor, and the adjustment time of coal selecting product index control is long, and the use amount of floating agent is big, these shortcomings have reduced the accuracy and the reliability that detect, also improve the cost of coal separation, therefore be necessary to take advanced detection method to detect coal preparation plant's flotation tailing ash content, to raise the efficiency and to reduce cost.
Summary of the invention
Technical matters to be solved by this invention provides a kind of flotation tailing ash content on-line measuring device, and this on-line measuring device can directly be measured coal preparation plant's flotation tailing ash content by the image processing and analyzing method, effectively improves detection accuracy and reliability.
The technical scheme that solves the problems of the technologies described above is:
A kind of flotation tailing ash content on-line measuring device, it is formed by suspension bracket, vision sensor, permanent light source, zoom lens, protective cover, computing machine and display are installed, suspension bracket is installed to be connected with protective cover, vision sensor, permanent light source, zoom lens connect successively, and be installed in protective cover inside from top to bottom, preparation power supply and signal transmission interface on the vision sensor, vision sensor is connected with computing machine and display by signal transmission wire, and protective cover below probes into that the mine tailing liquid level of mine tailing case is following directly to be contacted with mine tailing.
Above-mentioned flotation tailing ash content on-line measuring device, described protective cover is cylindrical, and the protective cover bottom is equipped with the clear glass guard shield, and the transparent glass cover lower end directly contacts with the interior liquid of mine tailing case, can directly observe the real-time status of flotation tailing, the protective cover inside surface is coated with reflector layer.
Above-mentioned flotation tailing ash content on-line measuring device, described protective cover be installed in the mine tailing case directly over, vision sensor and mine tailing case in the protective cover are vertically opposite.
Above-mentioned flotation tailing ash content on-line measuring device, described permanent light source is cold light source.
The invention has the beneficial effects as follows:
Tailings ash content of the present invention detects and adopts original image gray-scale value comparison method to belong to original creation both at home and abroad, fills up this field blank both at home and abroad.
Vision sensor of the present invention is installed in the protective cover, protective cover is the permanent light source chamber of sealing, the image acquisition region of protective cover is in below the mine tailing liquid level, and no ambient light is shone and the environmental change influence, and the picture signal that zoom lens and vision sensor are gathered to the ash content measurement accurately, reliably.
The invention solves the difficult problem that the flotation tailing ash content can't directly be measured, overcome the shortcoming that Error and Assay is big, real-time is poor, labour intensity is big, operation is loaded down with trivial details that existing artificial sample, oven dry, sample preparation bring, reduced the adjustment time of coal selecting product index control, reduce the use amount of coal preparation plant's floating agent, effectively improved detection accuracy and reliability.The present invention is applicable to that coal industry fluid ash content detects, and the automatic on-line that is particularly useful for coal preparation plant's ore pulp ash content detects.
