Problems solved by technology

[0002] In the current production of ceramic tiles, the heat source in the pulverizing workshop of most manufacturers is the coal-water slurry furnace. The finely ground coal-water slurry is burned through the coal-water slurry furnace, and the hot air is sent to the spray drying tower to make powder and burn. The final ash is discharged as garbage and pollutes the environment. Therefore, it has become an inevitable trend to provide a technology for recycling the ash

Embodiment Construction

[0024] The present invention will be further described below in conjunction with embodiment:

[0025] Fly ash ceramic bricks are prepared from raw materials with the following mass fractions:

[0026] Diopside 4%

[0027] Laiyang soil 27%

[0028] Mengyin feldspar 23%

[0029] Laiwu feldspar 24%

[0030] Raw coke 7%

[0031] High-density porcelain stone 8%

[0032] CWS furnace ash 7%.

[0033] In the preparation process of fly ash ceramic bricks, 5% of the total mass of the above-mentioned raw materials is added to waste bricks.

[0034] The preparation method of fly ash ceramic brick is:

[0035] The above raw materials were mixed and ground, and the fineness of the mud grinding was 250 mesh sieve with a residue of 5%, the firing temperature was 1170°C, and the firing temperature was 40 minutes.

[0036] Product testing indicators are as follows.

[0037] Product implementation standard: Appendix K of GB / T4100—2006, tested by the Bureau of Technical Supervision, the ...

Abstract

The invention relates to a coal ash ceramic brick and a manufacturing method thereof, and belongs to the field of ceramic preparation methods. The coal ash ceramic brick is characterized by being prepared by the following raw materials by mass percent: 4% of diopside, 27% of Laiyang soil, 23% of Mengyin feldspar, 24% of Laiwu feldspar, 7% of green coke, 8% of high-density china stone and 7% of water coal slurry ash. The water coal slurry ash is no longer discharged to the outside, so that the production cost is greatly reduced. As the water coal slurry ash has no plasticity but a higher iron content, the ligand strength is enabled to meet the standards through adjusting a formula. The color of the produced blank body is slightly yellow than before, but the physicochemical indexes are all not less than those before. During operation, a production line can be applied without any change after the formula of the blank body is adjusted only.

Description

technical field [0001] The invention relates to a fly ash ceramic brick and a preparation method thereof, belonging to the field of ceramic preparation methods. Background technique [0002] In the current production of ceramic tiles, the heat source in the pulverizing workshop of most manufacturers is the coal-water slurry furnace. The finely ground coal-water slurry is burned through the coal-water slurry furnace, and the hot air is sent to the spray drying tower to make powder and burn. The final ashes are discharged as garbage and pollute the environment. Therefore, it is an inevitable trend to provide a technology for recycling the ashes. Contents of the invention [0003] According to the deficiencies of the prior art, the technical problem to be solved by the present invention is: to provide a fly ash ceramic brick and its preparation method, realize waste utilization, reduce production cost, and reduce environmental pollution. [0004] The technical scheme adopted...
