Method for manufacturing intermediate-aperture empty nest bricks

Abstract

The invention relates to a method for manufacturing intermediate-aperture empty nest bricks, and belongs to the technical field of chemical artificial stone. The method for manufacturing the bricks comprises the following steps that (1) burdening is carried out; (2) above raw materials are put into a stirring machine to be stirred for 5 min to 7 min; (3) the mixed raw materials are directly conveyed to a vacuum extruder through a rubber belt conveyor for extrusion forming; (4) semi-finished green bricks are formed after the raw materials pass through an automatic green brick cutting machine; (5) the semi-finished green bricks are stacked on a drying vehicle and fed into a drying chamber to be dried; and (6) an energy-saving annular kiln is adopted for carrying out roasting, and the sintering temperature ranges from 950 DEG C to 1,100 DEG C. According to the method for manufacturing the bricks, the light bricks can be made by comprehensively utilizing building rubbish and waste polystyrene.

Description

technical field [0001] The invention relates to a method for manufacturing empty-nest bricks with medium apertures, and belongs to the technical field of artificial stone in chemistry. Background technique [0002] At present, the discharge of construction waste in my country is growing rapidly. According to statistics: only during the construction of new buildings such as brick-concrete structures, cast-in-place structures, and frame structures, 500-600 tons of construction waste will be generated per 10,000 square meters of construction. Today, the discharge of construction waste has accounted for 30% to 40% of the total amount of urban waste, most of which are transported to the suburbs or villages by the construction unit without any treatment, and are disposed of by open-air stacking or simple landfill, occupying a large amount of landfill. Land and consume a lot of shipping costs. At the same time, the dust generated in the process of clearing, transporting and stack...

Today, the discharge of construction waste has accounted for 30% to 40% of the total amount of urban waste, most of which are transported to the suburbs or villages by the construction unit without any treatment, and are disposed of by open-air stacking or simple landfill, occupying a large amount of landfill. Land and costly transportation costs

At the same time, the dust generated in the process of clearing, transporting and stacking causes environmental pollution.

[0003] In addition, as far as the applicant knows, the wide use of polystyrene products has brought a lot of convenience to people, but because waste polystyrene is difficult to compress and degrade, and people lack sufficient awareness of environmental pollution caused by waste foam plastics, The used waste foam plastic products are discarded at will, and polystyrene has the characteristics of aging resistance, refractory degradation, and corrosion resistance, which has caused serious harm to the environment and has become a major problem in garbage disposal
