Description
Technical field:
The present invention relates to filter block, be specifically related to a kind of production method of baking-free natural-minerals adsorptive filter block.
Background technology:
For production efficiency and the economic benefit that improves breeding water body, plant takes the high density intensive culture mostly, the balanced capacity of water ecosystem is limited, the high density intensive culture, a large amount of bait throwing in easily cause water body dissolved oxygen deficiency, cause and produce a large amount of organic matters in the water, algal grown is too fast, water colour changes greatly, and the pH value is unstable, and ammonia-nitrogen content exceeds standard.For making the limited maximum production capacity of breeding water body performance, must keep good water quality environment condition, this just must solve by loose, the corrupt water pollutions that caused of organic matter such as residual bait and excreta, minimizing is owing to the excessive harm that causes of harmful substance, the raising culture benefit.
In the process for purifying of breeding water body, begun to use filter block to carry out purification of water quality, Gong Ying filter block has in the market: ceramic filter piece, plastics filter block and stainless steel cloth filter block etc., the material of these filter blocks is made up of raw materials such as potter's clay, quartz sand, steel wire, plastics and strings mostly, absorption property is relatively poor in actual applications, biofilm efficient is low, is unfavorable for the growth and breeding of biological bacteria, can not effectively reduce the ammonia-nitrogen content of breeding water body.
Chinese patent publication number CN1594223, open day is on March 16th, 2005, name is called " a kind of production method that is applied to the porous filtering pottery of water treatment ", it discloses " a kind of production method that is applied to the porous filtering pottery of water treatment, it comprises batching, slurry and foams mix, irritates operations such as mould, high temperature sintering; The employed mould of production method of the present invention can adopt common plastics to make, thereby can reduce the cost of mould, correspondingly can reduce production cost of products, improves the competitiveness of product in market; The present invention is widely used in culturing the water treatment field of industry ".
The foregoing invention weak point is:
1, porous ceramics just contains concavo-convex rod in the base, is putting into kiln at 1000-1500 ℃ scope constant temperature sintering after 3-5 hour, and the crystal structure of concavo-convex rod has suffered serious destruction, greatly reduces the absorption property of concavo-convex rod.
2, cement, gypsum, quartz sand and the concavo-convex rod in the batching put into kiln at 1000-1500 ℃ scope constant temperature sintering after 3-5 hour, be molten condition, the bubble that foaming agent produced and the space that forms will significantly reduce, therefore can cause retaining power not strong, biofilm efficient is lower, the growth and breeding that is unfavorable for biological bacteria can not effectively reduce the ammonia-nitrogen content of breeding water body.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, provide that a kind of production technology is simple, absorption and strainability is good, biofilm efficient height, help the production method of the baking-free natural-minerals adsorptive filter block of biological bacteria growth and breeding.
The production method of baking-free natural-minerals adsorptive filter block is: baking natural-minerals adsorptive filter medium is transported in the mixer, adding cement, quartz sand and water stirs, join after stirring in the adsorption filter block mould, the working pressure machine is pressed into the semi-finished product of baking-free natural-minerals adsorptive filter block, semi-finished product are sent into the conventional maintenance of carrying out cement products in the maintenance room, dry the back naturally and be the finished product of baking-free natural-minerals adsorptive filter block.
One, the production method of baking natural-minerals adsorptive filter medium:
Zeolite, Concave-convex clay rod acidifying after, bentonite acidifying after, diatomite acidifying after, volcanic rock and the alumine of the batching of baking natural-minerals adsorptive filter medium after by acidifying formed.
The production method of baking natural-minerals adsorptive filter medium is: mix in the batching input mixer with baking natural-minerals adsorptive filter medium, be input to after mixing to push in the extruder and be tablet, and tablet is transported to the cement threshing ground carries out airing, to pulverize in the input of the tablet after the airing pulverizer, the particle transport of pulverizing is carried out roasting to roaster, be packaged as finished product after the cooling.
Zeolite can be selected some heavy metal of exchange, can be used for removing heavy metal ion, zeolite has very big specific area, can produce bigger extension, be outstanding adsorbent, and it not only can regulate water quality zeolite, remove the harmful substance in the water body, and mycotoxin had detoxification, can also promote the growth and breeding of beneficial organism bacterium in the breeding water body, to reduce the ammonia-nitrogen content of breeding water body.Zeolite behind acidifying and the high-temperature activation contains a large amount of holes, nutrients can be adsorbed in its a large amount of hole, directly award the breeding place of planktonic organism the best, keep the stable and content of microorganisms of water colour, because zeolite has very strong suction-operated, organic, harmful substance can be adsorbed in the hole of zeolite.
Concave-convex clay rod soil property exquisiteness, smooth surface, be viscosity and plasticity when moist, its viscosity can reach more than the 3000mPas, and dry contraction is little, and do not produce be full of cracks, help the bonding between the filter block raw material, the hardness of Concave-convex clay rod is Mohs 2～3 degree, when sintering temperature reaches 450～650 ℃, the hardness of Concave-convex clay rod rises to Mohs 5～6 degree, can guarantee the active strength of baking natural-minerals adsorptive filter medium; After the Concave-convex clay rod acidification, specific area can reach 350m
2More than/the g, its absorption property is greatly improved.
Bentonite has higher molecule porosity, and higher plasticity and stronger caking property are arranged, and hot green tensile strength and dry-pressing intensity are higher; Stronger cation exchange capacity (CEC) is arranged, all gases, liquid, organic substance are had certain adsorption capacity, maximal absorptive capacity can reach 5 times of weight to it, and the bentonite after the acidification can be adsorbed with color substance.
The diatomite mineral deposit belongs to the siliceous rock biochemical deposit origin cause of formation, be by the accumulation of Diatomeae animal and other biological siliceous skeleton part and thereupon transformation form, because diatomite has characteristics such as exquisiteness, loose, light weight, porous, suction and permeability are strong, diatomite after the acidification, its special structure structure makes it have many special technique and physical property has obtained further raising, as big porosity, stronger adsorptivity, and certain intensity is arranged.
Volcanic rock is a kind of coarse, lightweight, porous and the higher ore of water absorption rate that the volcanic eruption overflow forms, and can improve the performance of its absorption biofilm.
Alumine is through after the roasting, and its inner crystallization water, constitution water, attached water overflow, and by dredging, pine, softly becoming fine and close hardly, helps increasing the bulk strength of filter block on the structure.
