Embodiment

[0021] A method for manufacturing large-aperture empty-nested bricks in this embodiment includes the following steps:

[0022] 1) Select the following component raw materials by mass:

[0023] Component 1: Clay: 45-75 parts;

[0024] Component 2: through the double-roller crusher, it is directly crushed into brick-making and concrete structure construction waste powder of less than 10 mm: 30-50 parts;

[0025] Component three: water: 16-18 parts;

[0026] Component 4: 0.7-1.1 parts of polystyrene spherical particles with a particle size of 1.0-1.2 mm;

[0027] 2) Put the above raw materials into the mixer and stir for 5-7 minutes;

[0028] 3) The mixed raw materials are directly conveyed by the belt conveyor to the vacuum extruder for extrusion molding;

[0029] 4) Form semi-finished adobes after passing through the automatic adobe cutting machine;

[0030] 5) Stack the semi-finished bricks on the drying car and send them into the drying room for drying;

[0031] 6) The ...

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...
