According to the online testing device, an original image grey value comparison method is used for testing the flotation tailing ash content and is original at home and abroad, and the blank in the field at home and abroad is filled. The problem that flotation tailing ash content cannot be measured directly is solved, defects of large test errors, poor real-time properties, large labor intensity and tedious processes caused by prior manual sampling, drying and instantaneity are overcome, the adjusting time of prepared coal product index control is reduced, the usage amount of flotation reagents of coal preparation plants is reduced, and the accuracy and the reliability of testing are effectively improved.
Description
Technical field
This is practical newly relates to a kind of on-line measuring device that detects coal preparation plant's flotation tailing ash content, belongs 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 of the coal of producing is high, this batch coal is defective; Even if institute's producing coal charcoal ash rate customer requirements is low little by little, in hundreds and thousands of ten thousand tons, wherein the fine particle coal through floatation process accounts for 20% left and right that always enters the amount of washing due to institute's coal washing, accumulation gets up also will cause larger economic loss and energy dissipation.Therefore rationally control the floating product ash content 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 large, operation is loaded down with trivial details, error is large, real-time is poor, and the adjustment time that the coal selecting product index is controlled is long, and the use amount of floating agent is large, 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 costs.
The utility model content
This practical new technical matters to be solved is to provide 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 comprised of mounting suspension, vision sensor, permanent light source, zoom lens, protective cover, computing machine and display, mounting suspension is connected with protective cover, vision sensor, permanent light source, zoom lens connect successively, and be arranged on from top to bottom protective cover inside, preparation power supply and signal transmission interface on 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 tailing tank 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 tailing tank, 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 arranged on tailing tank directly over, vision sensor and tailing tank in protective cover are vertically opposite.
Above-mentioned flotation tailing ash content on-line measuring device, described permanent light source is cold light source.
This practical new beneficial effect is:
This practical new tailings ash content 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.
This practical new vision sensor is arranged in 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, without ambient light, shines and the environmental change impact, and the picture signal that zoom lens and vision sensor gather to the ash content measurement accurately, reliably.
This practical new difficult problem that the flotation tailing ash content can't directly be measured that solved, overcome the shortcoming that Error and Assay is large, real-time is poor, labour intensity is large, operation is loaded down with trivial details that existing artificial sample, oven dry, sample preparation bring, reduced the adjustment time that the coal selecting product index is controlled, reduce the use amount of Floatation Agents in Coal Preparation Plant, effectively improved detection accuracy and reliability.This practical coal industry fluid ash content that newly is applicable to detects, and the automatic on-line that is particularly useful for coal preparation plant's ore pulp ash content detects.
The accompanying drawing explanation
Fig. 1 is this practical new structural representation.
In figure, mark is as follows: mounting suspension 1, vision sensor 2, power supply input port 3, light source control mouth 4, signal transmission interface 5, permanent light source 6, zoom lens 7, protective cover 8, tailing tank 9, computing machine and display 10.
Embodiment
Basis is practical newly to be comprised of mounting suspension 1, vision sensor 2, permanent light source 6, zoom lens 7, protective cover 8, computing machine and display 10.
In figure, show, package unit is arranged on flotation machine tailing tank 9 tops, protective cover 8 belows probe into that the mine tailing liquid level of tailing tank 9 is following directly to be contacted with mine tailing, connection vision sensor 2, permanent light source 6, zoom lens 7 successively from top to bottom in protective cover 8, preparation power supply and signal transmission interface 5, power supply input port 3, light source control mouth 4 on vision sensor 2, vision sensor 2 is connected with computing machine and display 10 by signal transmission wire.
In figure, show, protective cover 8 is cylindrical, protective cover 8 bottoms are equipped with the clear glass guard shield, the transparent glass cover lower end directly contacts with the interior liquid of tailing tank 9, can directly observe the real-time status of flotation tailing, protective cover 8 inside surfaces are coated with reflector layer, form the permanent light source chamber of sealing, and the permanent light source 6 in protective cover 8 is cold light source.
