Build discarded object, Industry Waste cinder and Double shaft stirring is sent into via rubber conveyer with the ratio of 10%-30%, 50%-75%, 10%-25%
Machine, is stirred mixing, and the moisture content of domestic sludge, building castoff, Industry Waste cinder compound after stirring is 18%-
22%；Stir mixed domestic sludge, building castoff, Industry Waste cinder and ground via rubber conveyer feeding and practice equipment, grind and practice
After the completion of, carry out ripening；Domestic sludge after ripening, building castoff, Industry Waste cinder compound are carried out half
Hard plastic extrusion molding；The adobe of shaping is calcined by tunnel cave, sintering temperature is 950 DEG C -1100 DEG C, roasting time is
24h-36h, adobe need to be dried treatment before roasting, and after the completion of roasting, fired brick is prepared and completed.
Wherein, fired brick is that semi-stiff extrusion process or quadratic code burn.
Wherein, after crushing domestic sludge, building castoff, Industry Waste cinder press 15%-25%, 55%-70%, 15%-23%
Ratio be stirred mixing.
Wherein, after crushing domestic sludge, building castoff, Industry Waste cinder are stirred in 20%, 60%, 20% ratio
Mix mixing.
Wherein, domestic sludge be sanitary sewage is processed produced by sludge, building castoff includes the remaining mud of building
And architecture sediment.
Wherein, sintering temperature is 1000 DEG C, and roasting time is 30h.
The beneficial effects of the invention are as follows：The situation of prior art is different from, fired brick of the invention is obtained by following raw material,
Raw material by mass percentage, including component：10%-30% domestic sludges, 50%-75% building castoffs, 10%-25% industry waste coals
Slag.The fired brick prepared by said components, with the characteristic that intensity is big, lightweight, thermal resistance is big, as materials for wall, can expire
Sufficient wall demand, and it is small to the pressure of wall ground, while having excellent heat-insulating property.Above-mentioned domestic sludge, construction waste
Thing, Industry Waste cinder have similar part in nature with traditional brick-making raw material, can completely substitute traditional brick-making raw material, meanwhile,
Traditional handicraft need to add water when fired brick adobe is prepared, and the addition of moisture can be reduced using domestic sludge, or even completely not
With adding water, saving water resource.Fired brick preparation method of the present invention can not only realize that waste material is recycled, while can also be in waste material
Heavy metal carries out deeply-curing, it is to avoid environmental pollution.
