Currently, typically washing Jigging process includes following link:
(1) coal classification link: the raw coal of run coal bin passes through 40/200mm bilayer classifying screen (or single layer classifying screen 40/
Two sections of 200mm screenings), material, the material of 40-200mm and the material of 0-40mm greater than 200mm are sifted out respectively.
(2) sort link: the material of general 0-40mm is smalls, and smalls does not sort to be sold directly as thermal coal；It is greater than
The material of 200mm is crushed to after sorting out bulk spoil and sundries by picking less than 200mm；The material of 40-200mm and picking are broken
Material after broken enters jigging machine sorting together.Jigging machine makes water flow speed change up and down by air compressor machine air blast using water as medium
It moves (i.e. jigging), making material according to itself characteristic (density, granularity, shape), moving relative to each other is layered, finally
So that low density ore particle concentrates on top layer, the high ore particle of density concentrates on the bottom, to sub-elect spoil and cleaned coal.
(3) product dehydrate link: the spoil of jigging machine discharge is generally dehydrated by bucket elevator；The essence that jigging machine is selected
Coal generally passes through 2/40mm double layer dewatering screen (or two sections of single layer dewatering screen 2/40mm screenings) and is classified and is dehydrated, on upper sieve
40-200mm block cleaned coal passes through moisture general satisfaction requirement after dewatering screen, can sieve upper 2- directly as block cleaned coal product, lower screen
The fine cleaned coal of 40mm need to be dehydrated since granularity is thinner by small coal dewatering centrifuge.
(4) slime water treatment link: the centrifugation of water and centrifuge that water, the cleaned coal dewatering screen of bucket elevator removing are taken off
Liquid three is referred to as black water.Coal slime is divided into coarse granule and fine grained in black water, the former generally refers to the material of 0.25-2mm,
The latter generally refers to 0-0.25mm material.Slime water treatment need to be carried out dehydrating respectively according to thick, fine grain division.
(5) product blends link: general jigging block cleaned coal can be used as chemical industry coal or civil coal, and being needed according to market can also
To select after being crushed as power product of coal；General jigging fine cleaned coal, 0-40mm bypass smalls and coarse slime can be used as final dynamic
Power product of coal；The general moisture of fine coal slurry is bigger, calorific value is lower, general independent sale at low prices or directly dumps.
Above-mentioned washing Jigging process not only expends great lot of water resources, also has the disadvantages that
1) material layering is made to sub-elect spoil by the jigging process of jigging machine, so that spoil has certain band coal
Rate, usually 5%-6%, sharpness of separation are lower.
2) jigging sorting by water due to being sorted, it is also necessary to is equipped with dewatering system and is carried out dehydrating, so that sorting
Technics comparing is complicated.
3) since jigging sorting need to generate a large amount of coal slimes by water, the general moisture of coal slime is big, calorific value is low, encounters spoil
Easy argillization reduces the product quality and product yield of cleaned coal.
4) material size of the sorting of jigging machine have the upper limit, generally 200mm, can not to greater than 200mm material into
Row sorting, the material greater than 200mm can only be sorted after broken by jigging machine.
For convenient for understanding the present embodiment, first to a kind of raw coal sorting process disclosed in the embodiment of the present invention into

Small, the size of spoil and lump coal is bigger relative to smalls, smalls can be screened from raw coal, by what is mixed
Spoil and lump coal are used as to sorting material, and smalls does not need to be sorted, can be directly as power product of coal.
Step S2 identifies spoil and lump coal by material recognizing device.
Step S3 spoil or lump coal is discharged to sorting material by discharger, to sub-elect lump coal.
All lump coal sub-elected in S1- step S3 through the above steps constitute block cleaned coal product, can be used as chemical industry
It is used with coal or civil coal, in addition, lump coal can also be carried out after being crushed as needed as power product of coal.
Above-mentioned raw coal sorting process provided in this embodiment identifies spoil and lump coal by material recognizing device, and passes through
Spoil is discharged discharger, which is dry separation, does not need to avoid expending water resource using water as medium.Also, phase
For washing Jigging process, process flow is enormously simplified, without being carried out dehydrating and the links such as slime water treatment.
In step sl, raw coal can specifically be screened by the classifying screen being sized, filters out and is located on sieve
To sorting material, should be while to filter out greater than the material being sized and being located at lower being less than of sieve and set ruler to sorting material
Very little material, i.e., above-mentioned smalls.This is sized can according to need and be selected, it is preferred that is sized as 40mm.
It should be noted that since the color of spoil and lump coal, density, Texture eigenvalue are different, above-mentioned object
Material identification device can identify spoil and lump coal according to these features.
In a kind of optional embodiment, the material recognizing device in above-mentioned steps S2 can identify mould by X-ray
Block identifies spoil and lump coal.
Specifically, X-ray identification module can emit X-ray to spoil and lump coal, due to the density ratio lump coal of spoil
Density is big, so spoil is greater than lump coal to the absorption intensity of X-ray, so that after X-ray passes through spoil to the absorption intensity of X-ray
Residual intensity be less than X-ray pass through lump coal after residual intensity.Therefore, it may recognize that according to the size of above-mentioned residual intensity
Spoil and lump coal.
In another optional embodiment, in order to increase the accuracy of material recognition, identified in X-ray identification module
On the basis of, spoil and lump coal further can also be identified by picture recognition module.Due to the color of spoil and lump coal, texture
Etc. differences, therefore, picture recognition module can identify spoil and lump coal by identification color and texture etc..
In practical applications, material recognizing device and the discharger can be set in the same screening installation, be

It is configured according to specific needs, such as pressure P=0.8Mpa.
It should be noted that high pressure air feed system can not only spray spoil, it is also an option that lump coal is sprayed, this is
Because the spoil content in raw coal is likely less than lump coal, it is also possible to be greater than lump coal, if spoil content is less than lump coal, can incite somebody to action
Spoil sprays, if spoil content is greater than lump coal, lump coal can be sprayed, and so as to save high pressure wind-resources, reduces function
Consumption.
In practical applications, high pressure air feed system can use air compressor and air accumulator, will by air compressor
High-pressure blast is sprayed after gas compression in air accumulator.Specifically, a solenoid valve can be set in air compressor, when spoil passes through
When air compressor, solenoid valve is opened, and air compressor sprays high-pressure blast and sprays spoil, so as to avoid air compressor
High-pressure blast is sprayed always, and gas waste and power consumption is caused to increase.
Since certain moisture or oil may be contained in above-mentioned high-pressure blast, in order to avoid the drying of high pressure wind effect lump coal
Degree in the present embodiment, can also be dried high-pressure blast by drying equipment.For example, drying equipment can use
Freezing type drier, to realize that the oil removing to high-pressure blast removes purifying water process.
