Specific embodiment
Suspension flash of the present invention decomposes and homogenizing processing technique is achieved in that and does below in conjunction with the accompanying drawings specifically
It is bright.
See figure, suspension flash of the present invention decomposes and homogenizing processing technique, equipment by：Air-introduced machine 1, pulse dust collector 2,
Drawing-in device 3, raw material cabin 4, roller drier 5, calcining furnace 6, built in eddy current guidance system cyclone 7, discharge cut down 8, injecting type
Heat selects purifying machine 9, expensive goods collection device 10, air-introduced machine 11, expensive goods discharge to cut down 12, expensive goods storehouse 13, low-grade production
Product collection device 14, low grade products blow-off valve 15, low grade products storehouse 16, air-introduced machine 17 and combustion chamber 18 form.
Suspension flash of the present invention decomposes and homogenizing processing technique, comprises the following steps：
1st, raw material stores：Raw material is stored in raw material cabin 4；
2nd, raw material drying is handled：Raw material in raw material cabin 4 is uniformly sent into roller drier 5 by drawing-in device 3 to be dried
Processing, the dried lingering remnants of past customs are discharged after 2 dedusting of pulse dust collector by air-introduced machine 1；
3rd, dried raw material is calcined：Raw material after 5 drying process of roller drier evenly into calcining furnace 6 in into
Row calcination processing, combustion chamber 18 provide high temperature heat source for calcining furnace 6, and material absorbs the heat source that combustion chamber provides and reaches material
Grain itself decomposes；
4th, the finished product after calcining is collected：Calcining furnace 6 processing burn till product through efficient built in eddy current guidance system cyclone 7 into
Row finished product is collected；
5th, the product that burn till collected carry out sorting purification：Finished product is collected through efficient built in eddy current guidance system cyclone 7, is cut down through discharge
8 send to injecting type heat purifying machine 9 are selected to carry out high-grade purification processes；
6th, the high and low shelves product for sorting purification is collected, stores respectively：Expensive goods is by air-introduced machine 11 after heat choosing purification
The negative pressure of generation is directed to expensive goods collection device 10 and is collected, then is discharged to expensive goods storehouse through expensive goods blow-off valve 12
It is stored in 13；Low grade products is directed to low grade products collection device 14 by the negative pressure that air-introduced machine 17 generates and is collected, then through low
Shelves product blow-off valve 15, which is discharged in low grade products storehouse 16, to be stored.
Region is being sorted and purified, due to the respective property qualitative difference of material, distribution device and the homocline of purification section are selected in heat
Under the differential driving of device, with certain kinetic energy when particle moves, when movement velocity is identical, its kinetic energy of the big person of quality is also big,
I.e. motional inertia is big.When they are changed the active force of its direction of motion, since its inertia is different, different fortune can be formed
Dynamic rail mark is changed the movement locus of each material, and is aided with attached wall effect, finally there is vortex phenomenon and particle agglomeration phenomenon
Occur, until making to be sufficiently separated between each material, then material collections at different levels are got up to obtain expensive goods, low grade products.
Expensive goods is collected through air-introduced machine 11 to expensive goods collection device 10 after purified, then through 12 row of expensive goods blow-off valve
It being stored into expensive goods storehouse 13, low grade products is collected through air-introduced machine 17 to low grade products collection device 14, then through low grade
Product blow-off valve 15 is discharged in low grade products storehouse 16 and stores.
Suspension flash of the present invention decomposes and homogenizing processing process example
Magnesite flotation concentrate SiO2 in raw material cabin：0.13%； CaO：0.62%； F2O3 ：0.20%；Al2O3：0.06%；
MgO：45.98%, until ore dressing plant, after roller drier is dried, is equably fed in calcining furnace 6 and burning through drawing-in device 3
Room 18 provide high-temperature hot-air sufficiently contacted, in hot wind contact process, concentrate powder due to absorption hot wind contained by
Heat is contained and reaches itself and decompose, and index is as follows: SiO2：0.28%； CaO：1.43%； F2O3 ：0.47%；Al2O3：0.21%；
MgO：97.61%, fully decompose after burn till product again through efficient built in eddy current guidance system cyclone 7 collection after, set by lower part
Discharge cut down 8 and be fed to injecting type heat purifying machine 9 is selected to carry out heat and select purification processes, it is purified after expensive goods index it is as follows:
SiO2：0.16%； CaO：0.52%；
F2O3 ：0.08%；Al2O3：0.07%； MgO：98.45%, low grade products index is as follows:
SiO2：1.12%； CaO：1.87%； F2O3 ：0.75%；Al2O3：0.76%； MgO：87.75%, respectively by expensive goods
Collection device 10 and low grade products collection device 14 are collected storage, for use.
The present invention tests prove that：Magnesite concentrate powder after suspension flash decomposes and is homogenized the roasting of processing technique,
SiO2 can be produced：0.16%； CaO：0.52%； F2O3 ：0.08%；Al2O3：0.07%； MgO：98.45% expensive goods,
High-purity magnesium oxide criterion, low grade products SiO2 are reached：1.12%； CaO：1.87%； F2O3 ：0.75%；Al2O3：
0.76%； MgO：87.75%, also reach regular grade magnesia index request.
Using common suspension dynamic roasting technical products index：
SiO2：0.28%； CaO：1.43%； F2O3 ：0.47%；Al2O3：0.21%； MgO：97.61%, only do regular grade
Other magnesium oxide product uses.
Suspension flash of the present invention decomposes and homogenizing processing technique, the material of calcining furnace is fed, due to absorbing combustion chamber
The heat source of offer and reach material particles itself decomposition, region is being sorted and is purifying, due to the respective property qualitative difference of material, in heat
Under the differential driving of distribution device and homogenizing device for selecting purification section, with certain kinetic energy, movement velocity phase when particle moves
Meanwhile its kinetic energy of the big person of quality is also big, i.e., motional inertia is big.When they are changed the active force of its direction of motion, due to
Its inertia is different, can form different movement locus, be changed the movement locus of each material, and is aided with attached wall effect, most
There are vortex phenomenon and particle agglomeration phenomenon eventually, until making to be sufficiently separated between each material, then material collections at different levels are risen
Being to obtain expensive goods, low grade products.
Suspension flash of the present invention decomposes and homogenizing processing technique greatly reduces equipment investment, has the occupation of land face of reducing
Product reduces energy loss and consumption, extends service life of equipment, reduce repair density and expense, prevent the features such as environmental pollution,
It improves and stablizes finished product quality.
