Problems solved by technology

This invention uses raw materials such as Yellow River silt and industrial slag to prepare sintered bricks. Although it has achieved the purpose of turning waste into treasure and saving resources to a certain extent, it does not make full use of the existing waste, and there is a need for further optimization and improvement.

Embodiment 1

[0035] All waste sintered bricks are composed of the following raw materials according to weight percentage:

[0036] River silt 30%

[0037] Paper Mill Sludge 60%

[0038] Cinder 10%.

[0039] Among the above raw materials, the river silt used as the configuration raw material is dried and sun-dried river silt; the coal cinder used as the configuration raw material is the cinder after impurity removal and grinding.

[0040] Among the above-mentioned raw materials, the composition of the paper mill sludge as a configuration raw material, by weight percentage, includes:

[0041] Vegetable short fiber 50%

[0042] Nitrogen 15%

[0043] Phosphorus 15%

[0044] Potassium 20%.

[0045] Among them, plant short fiber is a kind of natural organic matter, which can make the inside of bricks more viscous and not easy to break when used in brick making.

[0046] This batching scheme is a preferred implementation of the present invention, which can make the produced fired bricks ac...

Embodiment 2

[0048] In this embodiment, the river silt, paper mill sludge and coal cinder used as configuration raw materials are the same as in Example 1, except that the river silt accounts for 40% by weight, and the paper mill sludge accounts for 30% by weight , The percentage by weight of cinder is 30%.

[0049] The described paper mill sludge as configuration raw material, its composition by weight percentage, comprises:

[0050] Vegetable short fiber 70%

[0051] Nitrogen 10%

[0052] Phosphorus 10%

[0053] Potassium 10%.

[0054] This batching scheme is a preferred embodiment of the present invention, which can make the produced fired bricks achieve better quality, and the specific weight of the product bricks is greatly reduced. It is determined that the density of the fired bricks of the present invention is about 13% lower than that of clay solid bricks. , The density of bricks made from pure silt is reduced by about 17%.

Embodiment 3

[0056]In this embodiment, the river silt, paper mill sludge and coal cinder used as configuration raw materials are the same as in Example 1, the difference is that the river silt accounts for 50% by weight, and the paper mill sludge accounts for 10% by weight , The percentage by weight of coal slag is 40%.

[0057] The described paper mill sludge as configuration raw material, its composition by weight percentage, comprises:

[0058] Vegetable short fiber 40%

[0059] Nitrogen 20%

[0060] Phosphorus 20%

[0061] Potassium 20%.

[0062] This batching scheme is a preferred embodiment of the present invention, which can make the produced fired bricks achieve better quality, and the specific weight of the product bricks is greatly reduced. It is determined that the density of the fired bricks of the present invention is about 16% lower than that of clay solid bricks. , The density of bricks made from pure silt is about 18% lower.

Abstract

The invention discloses an all scrap baked brick and relates to the field of scrap brickmaking. The baked brick is prepared from the following raw materials by weight percent: 30-90% of river mud, 5-60% of sludge of the paper mill and 5-40% of cinder, wherein the used river mud is dried and baked river mud, the used cinder is purified and grinded cinder and the used sludge of the paper mill comprises the following components by weight percent: 40-80% of short vegetable fiber, 10-20% of nitrogen, 5-20% of phosphorus and 5-20% of potassium. The all scrap baked brick of the invention adopts rivermud, sludge of the paper mill and cinder as raw materials so as to greatly reduce the specific gravity of the brick product; the test shows that the density of the baked brick of the invention is reduced by about 15% compared with the clay solid brick and by about 20% compared with the brick prepared from pure sludge. The all scrap baked brick has good economic benefit and environmental value andprominent comprehensive benefit.

Description

technical field [0001] The invention relates to the field of brick making from waste materials, in particular to a sintered brick made entirely of waste materials. Background technique [0002] River silt is a natural sediment formed by the flow of river water. It has a large amount and a wide area. If it is not treated and utilized, it will silt up and raise the river bed, forcing the river to overflow. If it encounters a flood season, it will be dangerous and seriously endanger the banks of the river. The lives and properties of the people are safe. The country spends a lot of manpower, material resources and financial resources every year on controlling river channel sedimentation. If the silt can be used well, it can not only turn harm into benefit, turn waste into wealth, save resources, improve the environment, but also be beneficial to river management. Simultaneously, the river bed after the silt is dug out will be silted up soon again. It can be seen that the rive...
