Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Nonmetal breeze only limits to brucite, tiff, quartz and sericite among this paper, and the order number is less than 100 orders, preferably 325 orders.This breeze obtains particle diameter after grinding be 3000～8000 purpose slurries.Slurry is meant the mixture of water and superfine powder among this paper, and when water cut was low, slurry can be filter cake shape, and when the slurry water cut was higher, slurry fluidity strengthened.When slurry is filter cake shape, also can realize the object of the invention.
Reforming apparatus embodiment
Referring to Fig. 1; Reforming apparatus provided by the invention, it comprises cylindrical shell 110, the induction trunk 130 that is communicated with cylindrical shell 110 bottoms, the outlet passageway 120 that is communicated with cylindrical shell 110 tops, cyclonic separator 400, induced draft fan 200, bagroom 300, is opened in slurry inlet 150 and properties-correcting agent inlet 140 on the sidewall of cylindrical shell 110 respectively.Cyclonic separator 400 includes the inlet mouth on the sidewall, the discharge port of bottom and the air outlet at top with bagroom 300.One end of outlet passageway 120 links to each other with the inlet mouth of cyclonic separator 400.The air outlet of cyclonic separator 400 links to each other with the inlet mouth of bagroom 300.The air outlet of bagroom 300 links to each other with induced draft fan 200.
This reforming apparatus also comprises first pipe connecting 151 that links to each other with slurry inlet 150.Slurry inlet 150 links to each other with an end of first pipe connecting 151.The other end of first pipe connecting 151 links to each other with the transfer lime of slurry.Among this paper in the slurry water cut indefinite, the gained slurry fluidity is better when water cut is higher, and water cut is mobile poor when low (like filter cake), then adopts screw rod extruding conveying this moment.Thereby e Foerderanlage can perhaps other can make devices of slurry inflow cylindrical shell 110 all can for pressure pump.The direction that slurry gets into cylindrical shell 110 is to extend along the direction of first pipe connecting 151.
This reforming apparatus also comprises second pipe connecting 141 that links to each other with properties-correcting agent inlet 140.One end of second pipe connecting 141 is fixedly connected on the outer wall of cylindrical shell 110.The other end of second pipe connecting 141 links to each other with the transfer lime of properties-correcting agent.Used properties-correcting agent can also can be liquid for solid, preferably properties-correcting agent is configured to liquid state during pan feeding.Properties-correcting agent gets into the cylindrical shell 110 from second pipe connecting 141.The direction that properties-correcting agent gets into cylindrical shell 110 extends to form for the direction along second pipe connecting 141.
During use, the warm air in air and the hotblast stove carries out feeding cylindrical shell 110 from induction trunk 130 after the heat exchange.Under the traction of induced draft fan 200, hot blast forms the air-flow of tornado in cylindrical shell 110.Fierce collision takes place with properties-correcting agent in the slurry that gets in the cylindrical shell 110 under the shear action of hot blast, mix fully, has just left particulate when surperficial at moisture, and the rapid and particle of properties-correcting agent reacts.The drop smooth surface.Because droplet profile is unstable, can merge after the drop of slurry and properties-correcting agent is touched mutually.Drop after the fusion gets into the exsiccant high temperature section under the transporting of high temperature gas flow, modified-reaction takes place.Water then evaporates and leaves.Thereby make the gained material not only satisfy dry requirement but also accomplished modification.The degree of activation of material is high after gained modification this moment.
After the droplet profile instability also can make slurry middle part separatory drop in to get into cylindrical shell 110, can meet once more and be fused into bigger drop each other.Properties-correcting agent also identical phenomenon can occur.If this moment, properties-correcting agent just met with slurry, then the improvement of the mixed effect of the two can not show a candle to when first dispersion forms drop, meet compatible effective.
Visible by above-mentioned analysis, the angle β between the feedstock direction that slurry and properties-correcting agent form in drying machine is the two key that whether can merge.For slurry and properties-correcting agent are mixed, the angle β between first pipe connecting 151 and second pipe connecting 141 is 0 °～360 °.This angle β also can be preferably 0～180 °.Referring to Fig. 1, angle β is meant that the extended line of medullary ray of extended line and second pipe connecting 141 of the medullary ray of first pipe connecting 151 intersects the gained angle.When first pipe connecting 151 and the vertical cylindrical shells 110 of second pipe connecting 141 are provided with, and first pipe connecting 151 and second pipe connecting 141 be when being in same horizontal plane, and angle β can be 0～360 °.When first pipe connecting 151 and second pipe connecting 141 are not in same plane, when being provided with for staggering, because the medullary ray of first pipe connecting 151 and the medullary ray of second pipe connecting 141 are one dimension, what the two surrounded can only be a two dimensional surface.Thereby the angle on this plane only limits to 0～360 °.Here 0～360 ° has comprised all angle values that can become.
After properties-correcting agent and slurry mix, at high temperature accomplish drying and modification and obtain material, leave cylindrical shell 110 from outlet passageway 120 after the mixing of materials.Under the traction of induced draft fan 200, material passes through separating material collection of cyclonic separator 400 and bagroom 300 successively with the mixture of gas.
Preferably, shown in Fig. 1 in the present embodiment angle β between first pipe connecting 151 and second pipe connecting 141 be 100 °.
Referring to Fig. 2, and the difference of embodiment 1 is that the angle β between first pipe connecting 151 and second pipe connecting 141 is 0 °, and apparently, when the two angle β was 0 °, slurry inlet 150 needed to be provided with at interval with properties-correcting agent inlet 140.
Referring to Fig. 3, and the difference of embodiment 1 is that the angle β between first pipe connecting 151 and second pipe connecting 141 is 180 °.
Referring to Fig. 4, and the difference of embodiment 1 is that the angle β between first pipe connecting 151 and second pipe connecting 141 is 90 °.When properties-correcting agent inlet 140 was opened in the top near cylindrical shell 110, from then on properties-correcting agent mouthful got into.Be merely 10% owing to reach the slurry water cut at cylindrical shell 110 tops, surface-moisture is few, and this moment, the reaction resistance of slurry and properties-correcting agent was little, and modified effect is best.
Referring to Fig. 5 and 6, be that with the difference of embodiment 1 first pipe connecting 151 and second pipe connecting 141 are in same plane, angle β is that the extended line of first pipe connecting 151 and second pipe connecting 141 intersects angulation, is specially 120 °.Even adopting this structure slurry therewith is that filter cake shape also can be realized.
Another aspect of the present invention also provides nonmetal breeze method of modifying, is used to handle the nonmetal breeze through grinding.This method comprises the steps: that nonmetal breeze after grinding, makes slurry.Afterwards this slurry is carried out drying.This moment, slurry and properties-correcting agent got into drying step simultaneously.Dry equipment therefor is above-mentioned reforming apparatus.
Properties-correcting agent used herein is a kind of or multiple arbitrarily in the group formed of Triple Pressed Stearic Acid, aluminic acid ester, zirconate, titanic acid ester and silicane properties-correcting agent.Silicane properties-correcting agent is the properties-correcting agent that contains element silicon and/or alkyl element, like vinyl silanes, organoalkoxysilane etc.The addition of properties-correcting agent can be the addition of properties-correcting agent commonly used.Be preferably 1～10% of solid masses in the slurry.Further be in the slurry solid masses 1～3%.
