Abstract
The present invention aims to solve river silt and shell recycling, provides a method for preparation of lightweight ceramsite from shells and silt, and belongs to the technical field of preparation of ceramsite from a mixed waste. The method is as follows: processed silt and shell powder and clay are mixed uniformly together, and added with water and stirred to prepare material balls; then the material balls are naturally dried indoors, and put into a furnace doe roasting; and the ceramsite is cooled with the furnace to obtain the lightweight ceramsite. Under the present to solve the recycling of the river silt and shells, a new lightweight ceramsite preparation method is provided, and the method is low in cost, and does not require expensive equipment. The method belongs to environmental waste recycling, and the lightweight ceramsite has excellent adsorption properties, can be used as a water quality conditioner, has a certain bactericidal effect, and is mainly used in the technical field of environmental protection, water filtration, construction and the like.
Description
Technical field
The invention belongs to and utilize mixed waste to prepare ceramic particle technology field, particularly a kind of method utilizing shell and mud to prepare light ceramic.
Background technology
In recent years, along with the development of sea farming industry and people are to the increasing demand of seashell products, coastland shell output raises year by year.Be used to owing to only having a fraction of shell that fancy goods makes, fodder additives and lime raw material etc., most shell is abandoned except arbitrarily toppling over after meat, and is difficult to degraded due to shell, causes serious environmental pollution to surrounding area.Shell mainly by 95% calcium carbonate and a small amount of organism form.Calcium carbonate is decomposed into carbon dioxide and porousness height adsorption and oxidation calcium through high-temperature calcination.
Riverway sludge is deposited on because current slow down the atrament that various organism on riverbed and inorganics formed through large quantitative response.In river course, toxic organics and heavy metal contaminants all deposit in mud.Therefore mud not only can make aggrade and affect river flood discharge capacity, and the mud of dredging also can cause secondary pollution through landfill or Land_use change.
Therefore, be necessary to recycle shell and riverway sludge, to eliminate waste pollution.
Summary of the invention
The object of the invention is the problem of the recycling in order to solve riverway sludge process and shell, providing a kind of method utilizing shell and mud to prepare light ceramic.The method is by treated mud, shell and clay, and add water stirring, makes pellet, after shaping pellet is placed in Indoor Natural drying, put into the high temperature resistance kiln roasting for some time cooling setting temperature increasing schedule, after haydite furnace cooling, i.e. obtained required light ceramic.The method is easy and simple to handle, effectively make use of waste, is the method preparing light ceramic of environmental protection.
Utilize shell and mud to prepare a method for light ceramic, comprise the steps:
(1) batching balling-up: get treated mud and oyster shell whiting, Homogeneous phase mixing together with clay, adds water after stirring, makes the pellet that diameter is 0.5 ~ 1cm;
Described treated mud and oyster shell whiting and clay adding proportion, be: mud 40-60%, oyster shell whiting 25-45%, clay 10-20% by weight percentage;
The treatment process of described mud is: removed slag by mud, remove foreign material, then mud is put into baking oven and dry to constant weight, then by broken for the mud after drying and be milled to 100 mesh sieves;
Described mud is riverway sludge, city inland river mud, lake silt etc.;
The treatment process of described oyster shell whiting is: rinsed well by shell clear water and put into oven for drying, then the shell of oven dry was milled to 100 mesh sieves;
(2) dry and roasting: after pellet being placed in Indoor Natural drying, putting into stove and be warming up to 1120 DEG C ~ 1180 DEG C with stove, then be incubated 30 ~ 60 minutes;
(3) cool: after haydite furnace cooling, i.e. obtained light ceramic.
After testing, the light ceramic that aforesaid method obtains meets the requirement of GB, and haydite diameter is 0.5 ~ 1cm, and density is 1.00 ~ 1.30kg/m
3.
Compared with prior art, feature of the present invention is:
1, compared to the method for traditional baking ceramsite, the present invention selects oyster shell whiting pyrolytic decomposition to produce gas to replace the foaming effect of general chemistry whipping agent, and the calcium oxide that oyster shell whiting pyrolytic decomposition generates has good absorption property, provides advantage for preparing drainage haydite.
2, the present invention utilizes the mud at the place such as river course, city inland river, lake to replace most clay, and the pollution problem not only solving mud also protects arable land.
3, present method belongs to environmental waste recycling, and gained light ceramic good adsorption performance, can be used as improver of water quality, and has certain germicidal action, is mainly used in the technical fields such as environmental protection, drainage, building.
