Description
Technical field
The present invention relates to haydite prepare the field of test technology, specially it is a kind of prepare extruding dregs porcelain granule during alkali gather materials instead
The method answered.
Background technique
Haydite is exactly the particle of ceramic, and the external appearance characteristic of haydite is largely rounded or oval-shaped ball, but there are also
Imitative rubble haydite is not round or ellipse sphere, and is in irregular rubble shape, and haydite shape is different because of technique difference, it
Surface is one layer of hard shell, this layer of shell is in ceramic or enamel, there is water proof to protect gas effect, and it is higher to assign haydite
Intensity, Lightness is the most important and its main reason for capable of replacing heavy sandstone in many excellent performances of haydite,
There are many raw material for producing haydite, and it is sallow there are also special kinds that the color for roasting haydite, which is mostly kermesinus and ember,
Color, grey black, canescence and cinerous etc., baking-free ceramicite varies in color because solid waste used is different, generally greyish black
Color, the lackluster degree in surface are smooth not as good as roasting haydite.
The inner structural features of haydite are in fine and closely woven honeycomb micropore, these micropores are all case type, rather than communicate-types
, and alkali refers to the change that the aqueous slkali in concrete aggregate or haydite in certain active minerals and haydite micropore generates
Learn reaction, alkali is divided into three types: (1) alkali-oxidation pasc reaction, (2) alkali-carbonate reaction and (3) alkali-silica are anti-
It answers, since alkali is usually to occur in concrete or gradually after the haydite several years after molding, result causes its resistance to
Long property decline and reaction product volume increase, and destroy so as to cause concrete or haydite structure, Chinese patent CN
104163617 A provide the application of a kind of haydite production method and haydite and haydite, which is a kind of good functionality
Water treatment filler, due into haydite rough surface there is bigger serface to be easy to bio-film colonization effect by high-temperature calcination, and
And light intensity height can bear high load capacity hydraulic blow with stability for a long time, and there is bio-film colonization to carry out denitrification dephosphorization function,
It is a kind of filler that water treatmenting performance is excellent, can be used for the water treatment technologies such as biofilter, artificial swamp, but it is in production
Still there is the problem of by alkali, it is difficult to determine the degree of the haydite alkali resistant aggregate reaction, so propose a kind of prepare
During extruding dregs porcelain granule the method for alkali come solve the problems, such as it is above-mentioned proposed in.
Summary of the invention
(1) the technical issues of solving

Amount just reduce by 0.15%, the low-sulfur fire coal after incorporation is transmitted in cooling device, cooling device to high-titanium blast furnace slag into
Row water spray chilling；
3) projectile is air-cooled, and the high-titanium blast furnace slag after anxious jelly is cooling is passed in casting device, and casting device will still be located
High-titanium blast furnace slag among quenching process is smashed rapidly and is popped up along different parabola, high-titanium blast furnace slag ejection process
Middle generation mutually collision, is cooled down with blast furnace slag in collision process by natural wind casting；
4) cooling mixing, the high-titanium blast furnace slag after ball blast enter in the dreg collecting slot with cooling water carry out it is cooling and
Mixing, blast furnace slag mix in dreg collecting slot with cooling water, and explosion and further depth extruding occurs, to generate the extruding with water
Slag；
5) transmission water removal, extruding slag burst in dreg collecting slot after twenty minutes from slag-drip opening be discharged, and by transmitting device by its
It is transmitted to dry pit, and the extruding slag with water removes water in dry pit, and extruding slag is got after water removal；
6) it is crushed molding, the hopper of crusher system is transferred to after the extruding slag after natural drying, after broken crusher machine
Extruding slag particle diameter be respectively less than 20mm, extruding slag particle of the last partial size less than 20mm enters crushing and screening device, and extruding slag is through broken
Broken and screening obtains the extruding solid impurity particle that partial size is 4.75~20mm, which is extruding dregs porcelain granule, the extruding slag
Its sulfide and sulphates content, which are respectively less than, after haydite molding is equal to 1.0%, and should carry out alkali after the molding of extruding dregs porcelain granule and gather materials
Reaction test, experimental condition are phenomena such as whether there are cracks, fracture and colloid are excessive, and expansion rate is answered small within defined test age
In being equal to 0.10%, and experimental enviroment is maintained at 20 ± 5 degrees Celsius.

Expect reactivity worth, can effectively enhance the mixing uniformity of extruding dregs porcelain granule in this method, extruding is obtained by broken and screening
The partial size of solid impurity particle (i.e. extruding dregs porcelain granule) is 4.75~20mm, and alkali inhibitor is uniformly mixed with it, can
Extruding dregs porcelain granule is effectively reduced integrally inhibits the phenomenon that alkali performance is insufficient, so that effective solution haydite is producing
When without alkali test make it difficult to determine the haydite alkali resistant aggregate reaction degree the problem of.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
