Description
Technical field
Present invention relates particularly to a kind of method utilizing mud and building castoff sintering self-insulating brick.
Background technology
At present, building trade is flourish, huge to the demand of fired brick, and country has forbidden clay solid brick
Use and produce, using solid waste brickmaking to become the trend substituting clay-brickmaking.Along with China's urban wastewater treatment firm
Building, the generation amount of its mud also sharply increases.Mud is organic by Organic substance, inorganic particle, colloid, heavy metal and persistency
Thing and microorganism etc. form, can be to environment if not being acted upon utilization.Building industry is produced as the mainstay of the national economy
One of industry, China has been achieved for the development advanced by leaps and bounds.Over the nearlyest 30 years, along with the high speed development of Chinese Urbanization, city
City updates rapidly, and construction scale constantly expands, and generation and the discharge of building castoff also grow at top speed.Low developed area and city
Overwhelming majority rubbish is unprocessed, directly transports countryside or rural area soot air storage or landfill to, takies a large amount of soil, make again
Become serious environmental pollution.Differ again on building castoff (brick and tile, concrete) and tradition clay brick raw material composition
, there is the difficulty of technology for fired brick in sample.How to deal carefully with mud and subway is cut the earth, it is achieved its recycling, and not
Pollute environment, be our urgent need to solve the problem.
Summary of the invention
The technical problem to be solved in the present invention, is that providing a kind of utilizes mud and building castoff sintering self-insulating brick
Method.
The present invention is achieved in that a kind of method utilizing mud and building castoff sintering self-insulating brick, including with
Lower step:
(1) sewage adds flocculation aid in settlement treatment process, and the mud precipitated is dehydrated through pressure filter, until mud
Moisture content reach 40%-70%, standby；Described sewage is the sewage handled by municipal sewage plant；
(2) building castoff accounts for more than 50% through the fine powder being crushed to particle diameter 60-70 mesh, remaining particle diameter 2.5mm with
Under, standby；
(3) by the building castoff mixing machinery stirring of the mud of 30-40 weight portion and 60-70 weight portion, the most pre-all
Change 6-12h, then be aged 12-24h；Use the operation of pre-homogenizing, make raw material mix homogeneously；
(4) the sulfate slag pore creating material mixing of 0.2-0.5 weight portion is added toward the raw material after ageing, it is thus achieved that blank；Sulfate slag
The interpolation of pore creating material makes green brick forming easy, and is provided that calorific value when burning, can form again microcellular structure, make sintering go out
Product can be incubated.
(5) blank is carried out under pressure 35-50MPa hydraulic pressure compressing, obtain adobe；Hyperpressure is compressing to be made
The self-insulating brick intensity prepared is high；
(6) adobe is sent into hothouse and is dried to moisture content is 5%-8%, is then fed into tunnel cave roasting, and sintering temperature is
950 DEG C-1050 DEG C, sintering time is 5h-8h, obtains self-insulating brick.
Further, described flocculation aid is blast furnace ash or flyash；The flocculation aid such as blast furnace ash or flyash is utilized to realize dirt
The efficient low-consume dehydration of mud.
Further, described self-insulating brick is solid brick, porous brick or hollow brick.
It is an advantage of the current invention that: utilize mud and building castoff fired brick, it is not necessary to burning coal powder in adding, it is achieved become useless
For precious, minimizing environmental pollution；Technique is simple, low cost, and intensity is high, and the heat transfer coefficient 0.3-1.35W/ (m of self-insulating brick2·
K), outward appearance is good.
