Description
Technical field
The present invention relates to a kind of apparatus and method for coal and spoil automatic sorting, belong to coal and gangue sorting skill
Art field.
Background technique
Since, containing the spoil of different proportion, spoil can generate the application of coal from raw coal mined in mine
Adverse effect, therefore in many applications, it requires using the coal after dressing of coal by washing.The washing of coal has very long go through
Shi Liao, the prior art are usually completes in coal washery to the dressing of coal by washing of coal, according to the property of coal with application demand not
Together, different washing process can be taken to be produced and processed, such as Jigging process, dense medium cyclone, dense-medium shallow-tank, flotation
Deng for coarse coal, or even passing through artificial hand selection.The techniques such as Jigging process, dense medium cyclone, dense-medium shallow-tank, flotation belong to often
Washing process is advised, technology is very mature, but a large amount of water and electric energy are consumed during coal separation, and equipment is built with workshop
If investing also larger.
In recent years, there is a kind of coal and spoil quickly distinguished on coal conveyer belt by on-line measuring device, and
Automatically control the equipment that separator separates coal with spoil.This technology is in the 1980s just it has been proposed that and tasting
Examination, but due to technical restriction, do not promote and apply success.With the progress of online measuring technique and automatic control technology, now
All having already appeared both at home and abroad can be with the equipment of practical application.This common working method of equipment is: lump coal being laid in special
Coal conveyer belt on, by online coal property test equipment, distinguishing every block of material is coal or spoil, in a delay time
Afterwards, the air nozzle array for driving coal conveyer belt end, opens the nozzle of corresponding position, spoil is blown away from coal, or
Coal is blown away from spoil, this is decided by the setting of system.This device is compared with traditional approach, in sorting lump coal side
Face has apparent advantage, specifically has: (1) whole equipment investment is far below traditional equipment.(2) water is not used, can be saved big
The water of amount.(3) a large amount of electric energy is saved.(4) without using ferromagnetic miberal powder needed for dense-medium separation, ferromagnetic miberal powder belongs to expendable material
Material, so as to save this part expense.Therefore coal enterprise will have very big demand to this equipment.This equipment is led at present
Often referred to as " intelligent dry separation ".But there is also defects for current intelligent dry separation: (1) the minimum granularity sorted is big, for small grain size
Coal can not sort；(2) due to using air blown coal or spoil, cause dust in workshop very big, it has to large size be installed and removed
Dirt equipment increases the demand of cost of investment, energy consumption, maintenance cost and installation space in this way；(3) it is sprayed using air
Blow, air from nozzle come out after, begin to scatter by not far, not only reduce push coal cinder power, also reduce blowing
Position precision, be not available intelligent dry separation so as to cause small grain size coal.
Mined coal generally all passes through primary breakup from mine, and maximum particle size is in 300mm.Using automatic dry
Choosing, can sort the lump coal of 30mm-300mm, this part lump coal is to be separated the coal for being less than the particle size range by screening system
It goes out, small grain size coal will be sorted into traditional washing system, can solve prior art presence if employed new technology
The problem of, further decrease intelligent dry separation sorts granularity lower limit, just means that this can improve the efficiency of separation, improves economic effect
Benefit.
