Description
Technical field
The present invention relates to dry coal preparation technical field, more particularly to a kind of gas-solid loop flow magnetofluidization sorting unit.
Background technology
AND ENERGY RESOURCES CONSUMPTION IN CHINA is big, maldistribution of the resources weighing apparatus.Most of energy source minerals especially coal, is distributed in northeast, west
The colds such as north, North China, arid area.Wet coal preparation water consumption is big, and dehydration is difficult and winter easily freezes, and is brought to transporting and utilizing
Great difficulty, itself is on the contrary into highly energy-consuming unit.Therefore dry coal preparation is especially suitable for these areas.
The dry separation of fine grained coal is particularly difficult.The magnetic field fluidized bed generation that can effectively prevent air pocket in bed body, can
With more effectively graded shot coal.Magnetic field fluidized bed described in patent CN200920047214.9, the coil in its generation magnetic field is
Circle, inside is square fluid bed.Limited by coil, sorting path is short, and the sorting time is few, and treating capacity is small.
The content of the invention
For above-mentioned problem, the present invention provides a kind of gas-solid loop flow magnetofluidization sorting unit, can be effective
Extend sorting path, the increase sorting time, improve the efficiency of separation and treating capacity.
To achieve these goals, the scheme that uses of the present invention is：A kind of gas-solid loop flow magnetofluidization sorting unit.Including ring
Shape bed body, feed hopper supporting plate, medium feed hopper, feeding-coal bucket, float discharge device, hypostasis hopper, angling hole air distribution plate, air
Dispersion layer, blast pipe, cloth wind bellows chamber, ajutage, air compartment and magnet coil.It is characterized in that feed hopper supporting plate is fixed on annular bed body
Above material feeding end, medium feed hopper and feeding-coal bucket are fixed on feed hopper supporting plate.Float discharge device rides fixation by buckle
In annular bed body, discharge height adjustable, hypostasis hopper is fixed on the tailing floss hole of annular bed body bottom.Angling hole cloth wind
Plate, air dispersion layer and air compartment stack the air outlet for being fixed on annular bed body bottom.Blast pipe is connected to cloth wind bellows chamber, ajutage
Connection cloth wind bellows chamber and air compartment, annular bed body are all positioned in magnet coil.
Invention has the following advantages compared with prior art：
Want to compare with classical magnetic field fluid bed, it is longer that gas-solid loop flow magnetofluidization sorting unit sorts the time in magnetic field, sorting
More fully, more efficient, treating capacity is bigger.
Brief description of the drawings：
Fig. 1 isometric views of the present invention；
The annular bed body front view of Fig. 2 present invention；
Fig. 3 present invention annular bed body back side top view；
Fig. 4 air distribution plate front views of the present invention.
Embodiment：
The invention will be further described below in conjunction with the accompanying drawings：The present invention includes annular bed body（1）, feed hopper supporting plate（2）, be situated between
Matter feed hopper（3）, feeding-coal bucket（4）, float discharge device（5）, hypostasis hopper（6）, angling hole air distribution plate（7）, air disperses
Layer（8）, blast pipe（9）, cloth wind bellows chamber（10）, ajutage（11）, air compartment（12）, magnet coil（13）Deng composition.
The course of work is：To magnet coil（13）It is powered, detects magnetic field intensity with magnetic field strong detecting instrument device, debug magnetic field
Apparatus system, the stable state of requirement to be achieved proceed by experiment in next step later.
Fine-grained magnetite powder passes through medium feed hopper as medium solid（3）It is added to annular bed body（1）In, compressed air passes through
Blast pipe（9）Enter cloth wind bellows chamber（10）In, pass through cloth wind bellows chamber（10）On the ajutage that is distributed（11）Feed respectively
Each air compartment（12）In, the air quantity of each air compartment can pass through ajutage（11）On valve regulated.Air is in air compartment（12）
In via angling hole air distribution plate（7）, air dispersion layer（8）, angling hole air distribution plate（7）The cloth wind system of trilaminate enters ring
Shape bed body（1）It is middle to form the air-flow for tilting injection.On the one hand the air flow component vertical with horizontal direction causes medium solid in bed body
Interior fully to fluidize, on the other hand the air flow component with horizontal direction parallel promotes medium solid to travel forward.Treat medium solid in bed body
Interior fully fluidisation passes through feeding-coal bucket again later（4）Coal sample is fed, coal sample is carried out in the exacerbation mass flow fully fluidized by density point
Layer, light product float over upper strata, sink to bottom under end-product.When reaching at discharge device, float discharge device（5）On scraper plate
The light product for floating over upper strata, float discharge device are scraped under the drive of motorized pulleys（5）Scraper height adjustable, can basis
Different situations come adjust scraper height, reach efficiency maximization.It is heavy that medium solid and coal sample mixture after discharge light product pass through
Thing hopper（6）Discharged from bed body bottom, complete whole assorting room.
