Abstract
The invention discloses the diatomite filler and the preparation method, which is composed by the followings based on the weight per centage: diatomite 83 per cent to 87 per cent, ferrous powder 8 per cent to 12 per cent and rice bran powder 4 per cent to 6 per cent. The diatomite, ferrous powder and rice bran powder are dried under constant temperature after mixing and dehydrated, and are added with the vesicant and binder to stir evenly and smash. The pelletizer is used to make the smashed materials spheric shape with diameter of 3mm to 6mm and the materials of spheric shape are calcined. During calcining, the coal is dried and grinded into powder and the air injection gear is used to spray the coal powder evenly on the materials of spheric shape. The diatomite filler is gained through sieving and grading after calcining. The diatomite filler of the invention has the advantages of being stronger in biological adhesion, strong in microorganism adhesion, richer in species, larger in specific area, high in porosity, stabler in water treatment facilities, less in energy consumption, light in weight and hard in wearing.
Description
Technical field
The present invention relates to water treatment field, a kind of specifically diatomaceous earth filler that is used for water treatment and preparation method thereof.
Background technology
The key of influence processing quality is the quality of filler in water treatment, and filler also plays crucial effect to the cost of water treatment simultaneously, at present, and the filler in domestic traditional filter tank, mostly be ceramic packing, exist than great, problems such as porosity is low, energy consumption is big, treatment facility instability.
Summary of the invention
Goal of the invention of the present invention is for providing the diatomaceous earth filler that a kind of specific surface area is big, porosity is high.
The technical scheme that realizes the foregoing invention purpose is as follows:
A kind of diatomaceous earth filler, form by following compositions in weight percentage:
Diatomite 83～87%
Iron powder 8～12%
Chaff powder 4～6%
Another object of the present invention is for providing a kind of preparation method of above-mentioned diatomaceous earth filler.
A kind of method for preparing above-mentioned diatomaceous earth filler comprises the following steps:
A. diatomite, iron and chaff are mixed the back freeze-day with constant temperature, remove moisture;
B. add whipping agent and binding agent, stir, pulverize;
C. with tablets press the material of pulverizing is made the sphere of diameter 3～6mm;
D. globular material is calcined;
E. in the calcination process, the coal drying is clayed into power, evenly be sprayed at the coal dust end on the globular material with air jet system;
F. sieve after the calcining, classification, promptly.
The diatomaceous earth filler profile that makes is spherical in shape granular, and apparent colour is grey, the brown or khaki color of ash, and concrete parameter is as follows:
Diameter: 3～6mm burning decrement 0.09 ± 0.001%
Wear rate: 1.5～2.5% apparent densities, 1.45～1.8g/cm
3
Percentage of damage is: 0.02～0.04%, and hydrochloric acid soluble rate: 0.5～1%
Tap density 0.7～0.9g/cm
3Pile up porosity: 45～55%
Diatomaceous earth filler of the present invention has provides a kind of light wear-resistant, and it is stronger to have biological adhesiveness, and microorganic adhesion is strong, species are abundanter, and specific surface area is bigger, and porosity is higher, water processing establishment is more stable, energy consumption advantage still less.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
A kind of diatomaceous earth filler, form by following compositions in weight percentage:
Diatomite 85%
Iron powder 10%
Chaff powder 5%
After a kind of method for preparing above-mentioned diatomaceous earth filler, the diatomite with 85%, 10% iron powder and 5% chaff powder are done main starting material and mixed, send into drying machine, carry out drying, constant temperature is removed moisture content and is entered weighing room then in drying machine.The whipping agent and the binding agent of adding 5% stir in weighing room.The material that stirs need enter in the pulverizer and pulverize, and particle diameter is worn into the feed bin that uniform particle diameter material enters tablets press again through pulverizer on request.Tablets press causes the sphere of 3～6mm diameter with mixture by the water technology requirement, and the spherical work in-process after the shaping are sent into calcination stage, carry out in rotary kiln during calcining, and controlled temperature is 1100 ℃.Need to add a certain amount of coal in calcination process, the coal of adding needs to use the Raymond mill porphyrize then through super-dry, adopts air jet system to spray on spherical raw material evenly again, enters rotary kiln.Fire and sieve immediately after finishing, with grading, the product after the classification cools off, after the cooling with finished product packing.
The parameter of the diatomaceous earth filler of present embodiment preparation is as follows:
Diameter: 3～6mm burning decrement 0.09%
Wear rate: 5.21% apparent density 1.45g/cm
3
Percentage of damage is 0.01%, hydrochloric acid soluble rate 0.21%
Tap density 0.7～0.9g/cm
3The intragranular pore rate is 16.2%
Claims (2)
1. diatomaceous earth filler, form by following compositions in weight percentage:
Diatomite 83～87%
Iron powder 8～12%
Chaff powder 4～6%.
2. a method for preparing the described diatomaceous earth filler of claim 1 comprises the following steps:
A. diatomite, iron powder and chaff powder are mixed the back freeze-day with constant temperature, remove moisture;
