Embodiment 1

[0015] A kind of preparation method of sintered brick, the concrete process step of this preparation method is:

[0016] 1. Prepare materials, select waste cinders, clay and water from power plants with insufficient combustion, take the production of a brick as an example, 115 grams of cinder, 2365 grams of clay, and 1000 grams of water;

[0017] 2. Pulverize, pass the collected unburned waste coal slag from the power plant through a pulverizer to make the pulverized particle size about 3 mm;

[0018] 3. Stir, send cinder and clay to the mixer with a conveyor belt, add water and stir evenly;

[0019] 4. Enter the brick making machine for extrusion molding, and then enter the billet cutting table to make bricks;

[0020] 5. Dry and dry naturally in the cool billet rack;

[0021] 6. Roasting, enter the brick kiln to be fired into finished products, the firing temperature is 850°C, and the firing time is 4 hours.

Embodiment 2

[0023] 1. Prepare materials, select slag, clay and water, take the production of a brick as an example, 130 grams of slag, 2370 grams of clay, and 1250 grams of water;

[0024] 2. Pulverize, pass the collected slag through a pulverizer so that the pulverized particle size is about 3 mm;

[0025] 3. Stir, send the slag and clay to the mixer with a conveyor belt, add water and stir evenly;

[0026] 4. Enter the brick making machine for extrusion molding, and then enter the billet cutting table to make bricks;

[0027] 5. Drying, put it into the cool billet rack to dry naturally, or enter the special drying room to dry;

[0028] 6. Roasting, enter the brick kiln to be fired into finished products, the firing temperature is 900°C, and the firing time is 4 hours.

Embodiment 3

[0030] 1. Prepare materials, select flue ash, clay and water, take the production of a brick as an example, 145 grams of flue ash, 2375 grams of clay, and 1500 grams of water;

[0031] 2. Crushing, if the particle size of the collected flue ash is relatively large, use a pulverizer to make the particle size of the pulverization less than 5mm;

[0032] 3. Stir, send the flue ash and clay into the mixer with a conveyor belt, add water and stir evenly;

[0033] 4. Enter the brick making machine for extrusion molding, and then enter the billet cutting table to make bricks;

[0034] 5. Drying, put it into the cool billet rack to dry naturally, or enter the special drying room to dry;

[0035] 6. Roasting, enter the brick kiln to be fired into finished products, the firing temperature is 950°C, and the firing time is 4 hours.

Abstract

This invention relates to a method for preparing sintered bricks. The method comprises: (1) selecting 115-145 parts of incompletely burned fly ashes, 2365-2375 parts of clay and 1000-1500 parts of water; (2) pulverizing incompletely burned fly ashes to less than 5 mm; (3) mixing the above raw materials; (4) molding in a brick maker, and making into green bodies; (5) drying and torrefying to obtain the final products. The method effectively uses incompletely burned fly ashes from electricity plant waste fly ashes, waste residues, furnace ashes, furnace rewsidues, flue ashes, etc., thus can save coal, reduce pollution and reduce the weight of sintered bricks. The sintered bricks have better quality than conventional clay bricks.

Description

technical field [0001] The invention relates to a method for preparing fired bricks. Background technique [0002] At present, in the preparation process of sintered bricks, it is a relatively common method to add an appropriate amount of coal to clay, mix and stir with water to make bricks, and then roast them. In this method, the coal in the mixture of coal and clay participates in combustion-supporting during roasting. On the whole, although the roasting time is reduced and a certain amount of coal is saved, it is necessary to add about 150- About 180 grams of coal still has the disadvantage of a large coal consumption. In addition, because in industrial production and people's daily life, there are a large number of power plant waste coal ash, waste slag, furnace ash, slag, flue ash, etc. that have not been fully burned. A lot of cost and inconvenience. Even though there are some application examples and technical literature of fly ash in bui...
