Description
Technical field
The present invention relates to haydite, and in particular to a kind of production method of multi-functional quincunx slag lightweight through hole haydite.
Background technology
In purification of water quality filtration treatment technique, need using substantial amounts of ceramic grain filter, the ceramic grain filter that tradition is used is
Using the raw material such as potter's clay, clay and flyash, after pelletize, high temperature sintering is formed.Cultivate or plant various nursery stocks, flowers and plants and vegetable
During dish, also frequently with lytag, leca, haydites of book structure and flower ceramsite as soilless culture substrate.
Lytag, leca and haydites of book structure are a kind of artificial lightweight aggregates, using high-quality clay, shale or fine coal
Ash is primary raw material, by rotary kiln high-temperature roasting, forms through expanded, is in alveolate texture as which is internal, thus has light
The features such as matter, high-strength, heat conductivity are low, water absorption rate is little,（Refer to national standard：GB/T 17431.1-2010 light-weight aggregate and its
Test method）.
As artificial lightweight aggregate is after high-temperature roasting, its surface forms one layer of enamel, although inside artificial lightweight aggregate be in
The micropore of alveolate texture, but, the micropore of internal cellular shape structure is a kind of closed pore, the micropore of alveolate texture not only that
Do not connect between this, and and external environment, water absorption rate is relatively low, is practically free of moisture inside artificial lightweight aggregate, will be artificial
Light-weight aggregate is put in water body, can only float on the surface of water, and therefore, artificial lightweight aggregate can only be sprinkling upon the top layer of soil, as one
Kind of decoration, can not be directly used in the plants such as the various nursery stocks of plantation, flowers and vegetable, also not be suitable for purification of water quality filtration treatment
In technique.
Chinese patent Authorization Notice No.：102503539 B of CN, authorized announcement date：On 04 17th, 2013, entitled " circle
Spherical attapulgite flower ceramsite ", discloses that " a kind of spherical attapulgite flower ceramsite, spherical attapulgite flower ceramsite is by height
Viscous attapulgite clay powder, attapulgite clay mine tailing, red bentonite in powder, sludge, kieselguhr mine tailing and powdered rice hulls group
Become.The dispensing of spherical attapulgite flower ceramsite is packaged as spheroidal through mixing, pelletize, roasting, cooling and screening concavo-convex
Rod flower ceramsite ".
Chinese patent Authorization Notice No.：100423808 C of CN, authorized announcement date：On October 08th, 2008, entitled " recessed
The production method of convex stick ceramic grain filter ", discloses " a kind of production method of concave convex stick ceramic grain filter, the main points of its technical scheme
It is that the production method of concave convex stick ceramic grain filter is：Dispensing, pulverizing, pelletize, roasting, sieve, be packaged as finished product.Concave convex stick ceramic grain
Filtrate is made up of attapulgite clay, gangue and volcanic ash ".
Spheroidal ceramsite preparation process：(1) first powdery dispensing is added in the comminutor for having operated, with the height for preparing
Pressure spray water spray solution is in powdery dispensing, and powdery dispensing is delayed by the vaporific aqueous solution adhesion of high pressure on the surface of powdery dispensing
A kind of bead of diameter less than 0.5 millimeter is processed into slowly, and bead continues to roll in comminutor；(2) vaporific water-soluble by prepared
Liquid is sprayed at the surface of bead, and the bead in comminutor is sufficiently moistened in operation process, then powdery dispensing is trickled down
On the surface of Shi Run bead, powdery dispensing parcel is sticky on the surface of bead, and the volume of bead is increasing；(3) through repeatedly weight
The vaporific aqueous solution of multiple sprinkling and powdery dispensing is trickled down on the surface of Shi Run bead, powdery dispensing and vaporific aqueous solution are one
In the encapsulation process of the another layer of layer, promote the volume of bead constantly to be increased, the overall process of pelletize is finally completed, is prepared into
A kind of higher spheroidal haydite of intensity.
As spherical granules internal structure is very closely knit, the effective specific surface area of spherical granules is greatly reduced, circle
The proportion of spheroidal particle and bulk density are all than larger.
Spheroidal haydite internal structure after roasting is even closer, although the spheroidal haydite intensity after roasting compares
Height, but more cause effective ratio area and significantly reduce, and proportion and bulk density are remained than larger, so as to significantly
Reduce absorption, purification, filter capacity and the water absorption rate of spheroidal haydite.
Spheroidal haydite is difficult to grill thoroughly completely in roasting process, inside haydite, by the spheroidal haydite that does not grill thoroughly
It is put in water and explosion and disintegrate can be produced, directly influences purification of water quality filter effect.
Test through multiple sampling：Artificial lightweight aggregate average bulk density >=800kg/m on the market, mean water absorption
Rate≤18%, spherical attapulgite flower ceramsite average bulk density >=850kg/m, mean water absorption rate≤50%, Attapulgite ceramic
Grain filtrate average bulk density >=950kg/m, mean water absorption rate≤40%.
By contrast, the bulk density of this several haydite causes effective specific surface area smaller, water absorption rate all than larger
Than relatively low, user wishes to invent that a kind of advantages of good adsorption effect, the rate of filtration be fast, bulk density≤800kg/m and water absorption rate >=
65% light ceramic, to be applied to purification of water quality filtration, soil remediation and various afforestation projects.
