Large-aperture empty nest brick manufacturing method

Abstract

The invention relates to a large-aperture empty nest brick manufacturing method, belonging to the technical field of artificial stones in chemistry. The brick manufacturing method comprises the following steps: (1) batching; (2) putting the raw materials into a stirrer and stirring for 5-7 minutes; (3) directly conveying the mixed raw materials to a vacuum extruder for extrusion molding by using a rubber belt conveyor; (4) forming semi-finished green bricks after the raw materials pass through an automatic brick cutter; (5) stacking the semi-finished green bricks on a drying vehicle and putting the semi-finished green bricks into a drying chamber for drying; and (6) carrying out calcinations by adopting an energy-saving annular kiln, and maintaining the sintering temperature to be 950-1,100 DEG C. The brick manufacturing method can comprehensively used for building rubbish and wasted polystyrene to prepare light-weight bricks.

Description

technical field [0001] The invention relates to a method for manufacturing large-aperture empty-nest bricks, 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 stacking cau...

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
