Abstract
The invention discloses a technique for identifying coal, coal gangue and iron ore by surface structure and texture, comprising a host machine, an industrial camera, a left side light source, a right side light source, a shell body and a crude coal conveying belt machine; the upper part of the shell body is provided with the host machine; the lower part of the shell body is equipped with the industrial camera; both sides of the shell body are respectively equipped with the a left side light source and the right side light source; the crude coal conveying belt machine is arranged beneath the industrial camera. The technique has the beneficial effects that 1, the surface shape and structure method is applied to efficiently identify the coal, the coal gangue and the iron ore; the method manually selected for identifying by eyes is replaced, the identifying working efficiency is improved, and the identification rate is also greatly improved; 2, by comparing with a moving sieve and a dense medium shallow slot which are identified and separated by applying hydration dense medium, the technique has the advantage of not using medium and stopping water pollution; meanwhile, the technique is also small in equipment volume, low in cost, and low in running cost, and so on.
Description
Technical field
The present invention relates to be identified using the method for surface texture and texture to the coal and gangue and iron block in raw coal
Technology.
Background technology
The quality of raw coal ature of coal is affected, mainly due to contained gangue in raw coal and the iron block (machine zero being usually scattered
Part etc. is mixed into raw coal, amount is little) number determined；If these gangues and iron block can be removed, the matter of raw coal
Amount just can be greatly improved.Want to remove these gangues, first have to effectively recognize coal and gangue and iron block.
The major way of gangue and iron block is recognized at present：One is by the knowledge (efficiency otherwise of eyes in artificial hand selection
Low, discrimination power is low)；Two be according to coal it is different with the proportion of gangue and by the way of the dynamic sieve and dense-medium shallow-tank of water and dense medium
It is identified separating (causing water pollution).
The content of the invention
To solve the above problems, the present invention provides what a kind of use surface texture and texture were recognized to coal and gangue and iron block
Technology.
The technical solution used in the present invention is：A kind of use surface texture and texture are to coal and gangue and the skill of iron block identification
Art, including main frame, industrial camera, left side area source, right side area source, housing and raw coal belt conveyer, the top cloth of housing
It is equipped with main frame；Industrial camera is installed immediately below housing；The both sides of housing are separately installed with left side area source and right flank light
Source, is raw coal belt conveyer below industrial camera.
Having the beneficial effect that produced by the present invention：
1st, efficient identification is carried out to coal and gangue and iron block using the method for surface configuration and structure, instead of artificial hand
Choose by eyes knowledge otherwise, improve identification operating efficiency, discrimination power is also greatly improved；
2nd, compare with dense-medium shallow-tank with being identified detached dynamic sieve by the way of water with dense medium, with not using Jie
Matter, prevents the advantage of water pollution.Have equipment volume little simultaneously, low cost, the low advantage of operating cost.
Description of the drawings
Technical scheme is further illustrated with reference to the accompanying drawings and detailed description.
It as shown is schematic structural view of the invention
In accompanying drawing：1- main frames, 2- industrial cameras, 3- left sides area source, 4- right sides area source, 5- housings, the conveying of 6- raw coal
Belt feeder.
Specific embodiment
As illustrated, the technology that a kind of use surface texture and texture are recognized to coal and gangue and iron block, including main frame 1,
Industrial camera 2, left side area source 3, right side area source 4, housing 5 and raw coal belt conveyer 6, the top of housing 5 is disposed with master
Machine 1；The underface of housing 5 is provided with industrial camera 2；The both sides of housing 5 are separately installed with left side area source 3 and right side area source
4, the lower section of industrial camera 2 is raw coal belt conveyer 6.
The left side area source 3 and right side area source 4 are respectively left side White LED area source, right side White LED face light
Source；
The present invention operation principle be：
Coal and gangue and iron block in raw coal, Jing raw coal belt conveyer 6 is delivered to immediately below industrial camera 2；Pass through
After White LED area source illuminates, industrial camera 2 just captures coal and gangue and the characteristics of image of iron block, and characteristics of image is passed
Main frame 1 is delivered to, system has the surface texture of complexity to the imagery exploitation coal for shooting in main frame 1, texture is more；And gangue surface
Structure is smoother, and texture is less, and iron block surface texture is simple, substantially no grain.This feature is identified to them
And differentiation, there is more or all surfaces product, be that the more raw coal of texture of complex surface structures is judged to coal；Have more or whole
It is gangue that surface area is the judgement that simple structure is smoother, texture is less；Surface texture is simple, substantially and veined does not sentence
It is set to iron block.
Easy to understand, the embodiment is only the part of the present invention, and those skilled in the art are not making creativeness
The other embodiment obtained on the premise of work, and the various changes and change without departing from spirit and scope of the invention for carrying out
Type, all should belong within protection scope of the present invention.
The technology not described in detail of the invention, shape, construction part are known technology.
