Embodiment 1

[0025] A method for producing porous shale sintered bricks using crystal solid waste shale gangue, the method comprising the following steps:

[0026] 1) According to 8% of construction waste, 20% of crystal solid waste, 42% of shale, 15% of coal gangue tailings, and 15% of road waste;

[0027] 2) Use shale as the main sintered brick material, mix crystal solid waste, and add coal gangue mine tailings, after crushing and vigorous stirring, add crystal wastewater with 15% of the total weight of solid materials during stirring, and mix evenly;

[0028] 3) After mixing evenly, the raw materials are sent to the storage room for plasticity treatment. After the plasticity uniformity reaches the molding requirements, the mixture is sent to the strong mixer through the grab machine and the conveyor, and then sent to the hard plastic extruder after stirring. All kinds of porous blocks are sent into the professional drying kiln, and the waste heat of drying is to use the waste flue gas ...

Embodiment 2

[0031] A method for producing porous shale sintered bricks using crystal solid waste shale gangue, the method comprising the following steps:

[0032] 1) According to 10% of construction waste, 12% of crystal solid waste, 50% of shale, 20% of coal gangue tailings, and 8% of road waste;

[0033] 2) Shale is used as the main sintered brick material, mixed with crystal solid waste, and coal gangue mine tailings are added, after crushing and strong stirring, crystal wastewater with a total weight of 10-15% of solid materials is added during stirring, and mixed evenly ;

[0034] 3) After mixing evenly, the raw materials are sent to the storage room for plasticity treatment.

Abstract

The invention relates to a method for producing a building material from solid wastes, in particular to a method for producing a porous shale sintering brick from crystal solid waste shale coal gangue. According to the method, crystal solid waste shale is used, coal gangue tailings are added in proportion, the mixture is crushed and strongly stirred, crystal wastewater is added during stirring and uniformly mixed, raw materials are sent into a storage chamber for plasticity treatment and can be sent into a strong stirrer by a grab machine and a conveyor and then sent into a hard-plastic extruder after being stirred to form various porous building blocks, the building blocks are sent into a special drying kiln by a ferry vehicle to be preheated, the mixture forms a porous brick, and the porous brick enters a calcining kiln to be calcined after being dried. The porous shale sintering brick has high strength, good durability, standard size, complete outline, uniform color and luster and as well as primitive, plain and natural appearance, can be used for a dry wall, and can also be used for any external decoration. Thus, the porous shale sintering brick replacing a clay brick is an upgraded new building material product with great development prospect.

Description

technical field [0001] The invention relates to a method for producing building materials from solid waste, in particular to a method for producing porous shale sintered bricks by utilizing crystal solid waste shale coal gangue. Background technique [0002] In Pujiang, known as the capital of crystal, the processing and sales of crystal materials have become one of the main sources of income for thousands of households. Its vigorous development has enriched the majority of peasant brothers, cultivated a large number of social talents, and also promoted the development of logistics, transportation, packaging and other related industries, and promoted the social and economic development of Pujiang. However, due to the characteristics of the crystal industry, such as low technical level requirements, many geographical distribution points, large quantities, and wide areas, the distribution of the entire industry is unreasonable; the processing of crystal materials in Pujiang Co...
