Description
Technical field
The present invention relates to haydite, be specifically related to a kind of gravel-shaped attapulgite bed-silt haydite.
Background technology
China worsens the dredging engineering generation of taking for administering water quality of landscape water dredging bed-silt amount increases day by day, due to the bed-silt water ratio greater than 75%, moiety is complicated, easily produce secondary pollution, mishandlingly will cause totally unfavorable impact to environment, thereby the treatment and disposal of dredging bed-silt just become people's question of common concern.
The plasticity-of bed-silt is better, but water ratio is large and content ferric oxide is lower, directly has influence on bed-silt haydite production cost and quality.
Chinese patent Granted publication CN 101531500 B, on June 22 2011 Granted publication day, name is called " with the method for firing ceramsite by using sludge ", discloses a kind of " method with firing ceramsite by using sludge.At first the method will carry out mud drying process through the sludge of sewage treatment plant after mechanical dehydration or lake, river Dredged Sludge in special mud drying device, the water ratio of mud and volume are down to respectively below 30% with below 1/3rd.Then by special press, mud is pressed into raw material ball, the mud raw material ball through the roasting of 1000～1100 ℃ after, form sludge ceramsite, when sludge ceramsite is fired, the hot flue gas of discharging is as the thermal source of sludge drying.The method is not only than the general haydite of firing for raw material with clay, sandy loam, shale etc., and power consumption still less, production cost is lower, and the recycling sludge of having opened up the treatment of wastes with processes of wastes against one another and recycling waste is processed new way ".
The weak point of above-mentioned patent is to carry out drying and drying and other treatment to mud, has greatly increased the production cost of haydite, and the haydite intensity of utilizing merely mud to produce is low and porosity is little, has influence on the result of use of haydite.
Summary of the invention
The objective of the invention is to overcome weak point in prior art, a kind of gravel-shaped attapulgite bed-silt haydite is provided.
Gravel-shaped attapulgite bed-silt haydite is comprised of the sticking attapulgite clay powder of height, attapulgite clay mine tailing, red bentonite in powder, bed-silt, flyash and wood dust.
The production method of gravel-shaped attapulgite bed-silt haydite: with the batching of gravel-shaped attapulgite bed-silt haydite through mixing, granulation, roasting, cooling, pulverize and screening after be packaged as gravel-shaped attapulgite bed-silt haydite.
Attapulgite clay be a kind of layer of chain-like structure contain Shuifu County's zeopan clay mineral, the attapulgite clay soil property is fine and smooth, water-absorbent is strong, tool viscosity and plasticity-when wet, be conducive to the bonding between raw material, can improve granule strength, sticking power and the porosity of gravel-shaped attapulgite bed-silt ceramsite sand.
High sticking attapulgite clay powder refers to get 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add again 372g water, the suspension cup is placed on homogenizer, stirred 20 minutes under the rotating speed of 11000 rev/mins, to pour in the beaker of 250ml through the high-speed stirring sample suspension again the viscosity of using NDJ-1 type rotational viscosimeter to test its suspension, tested viscosity value 〉=2200 into
MPasThe attapulgite clay powder be high sticking attapulgite clay powder, the height that the present invention selects glues attapulgite clay powder particles fineness≤0.074 millimeter.
Attapulgite clay can mix in recovery process a certain amount of rubble and earth, can't sieve, and abandons as a kind of mine tailing, causes a large amount of wastings of resources, the particle fineness of attapulgite clay mine tailing≤0.1 millimeter.
Red wilkinite iron oxide content is high, and water-absorbent is strong, has plasticity-and agglutinating value(of coal), is used for the present invention and can improves the intensity of gravel-shaped attapulgite bed-silt ceramsite sand and reduce sintering temperature;
Red wilkinite originates in horse race mining area, mountain, Gui Wu town, Xuyi County, Jiangsu Province, main component has quartz, montmorillonite, kaolinite, rhombohedral iron ore and feldspar, iron oxide content 〉=14%, aluminium sesquioxide content 〉=10%, common wilkinite iron oxide content≤5%, reserve have more than 1,000,000 tons, it is a surface mines, because purposes is not extensive, at present not yet can big area exploitation, the particle fineness of red bentonite in powder≤0.1 millimeter.
The bed-silt water ratio is greater than 75%, be difficult to carry out drying treatment, because bed-silt plasticity-is better, after the sticking attapulgite clay powder of height, attapulgite clay mine tailing, red bentonite in powder, flyash, wood chip and bed-silt are mixed, the water content of mixture can be below fast-descending to 20%, the particle fineness of bed-silt≤0.15 millimeter.
The flyash main component is silicon-dioxide, aluminium sesquioxide, ferric oxide, calcium oxide and uncompleted burned carbon, does not fire charcoal and is loose porous form more, the particle fineness of flyash≤0.1 millimeter.
It is in order to increase the porosity of gravel-shaped attapulgite bed-silt haydite that the present invention adopts wood dust, gravel-shaped attapulgite bed-silt haydite is in roasting process, wood dust burning in haydite is ashes, forms a large amount of micropores, the particle fineness of wood dust≤0.15 millimeter.
The present invention is achieved by following technical proposals:
1, the batching of gravel-shaped attapulgite bed-silt haydite is comprised of following component by weight percentage: high sticking attapulgite clay powder 1～10%, attapulgite clay mine tailing 5～25%, red bentonite in powder 5～20%, bed-silt 45～65%, flyash 5～20% and wood dust 1～10%.
2, the production method of gravel-shaped attapulgite bed-silt haydite: ⑴ adds input Squeezinggranulator granulation after stirrer for mixing with the batching of gravel-shaped attapulgite bed-silt haydite, particle diameter is controlled at 8～25 millimeters, and particle length is controlled at 20～40 millimeters; ⑵ the particle input internally heated type revolution roasting in kilns after with granulation, maturing temperature is controlled at 550～850 ℃, and roasting time is controlled at 1～5 hour; ⑶ pulverize as the gravel particle and sieve in the particle input crusher after with roasting, particle fineness is controlled at 1～12 millimeter, is packaged as gravel-shaped attapulgite bed-silt haydite.
Screening is chip and the ashes that produce in roasting and crushing process in order to remove gravel-shaped attapulgite bed-silt haydite.
The present invention does not need mud is carried out drying and drying and other treatment, greatly reduces the production cost of haydite.
Because the granule strength after granulation of the present invention is higher, when adopting the internally heated type rotary kiln to carry out roasting, maturing temperature is controlled at 550～850 ℃, compare with 1000～1100 ℃ of high temperature sinterings of ordinary method, have sintering temperature low, reduce energy consumption, the characteristics of the fast and low production cost of speed of cooling.
Gravel-shaped attapulgite bed-silt haydite is erose particle, and granule interior has a large amount of trickle pores, be a kind of lightweight, intensity is high, thermal conductivity is low, refractoriness is high, chemical stability is good, weather resistance and the good building porcelain granule of heat preservation and soundproof performance.
The present invention fully utilizes bed-silt and mine tailing is produced gravel-shaped attapulgite bed-silt haydite, not only is conducive to improve resource utilization, turns waste into wealth, and can also reduce land occupation, and protection of the environment and environment purification are to achieve many things at one stroke.
Gravel-shaped attapulgite bed-silt haydite is applicable to produce haydite concrete and heat-insulating and noise-insulating material.
