Abstract

The invention discloses a novel environment-friendly brick and a manufacturing method thereof. The novel environment-friendly brick comprises the following raw materials in percentage: 40 to 50 percent of half-finished waste, 40 to 50 percent of construction spent clay, 3 to 8 percent of coal slag, 2 to 6 percent of coal ash, and 1 to 3 percent of lime. The manufacturing method comprises the following steps: 1) mixing the compositions according to the proportion, stirring the mixture into mud after adding water; 2) fermenting the mud; 3) manufacturing an adobe by a brick molding machine; 4) drying; and 5) firing by a ring kiln. The invention has the advantages: 1) the half-finished waste and the construction spent clay are used as raw materials, thereby changing wastes into valuable, reducing waste pollution, and contributing to environmental protection; 2) clay resource is protected; 3) field for drying the brick is saved, and the production is not affected by season or weather; 4) residual heat can be recovered to save energy and reduce emission; and 5) environment-friendly facilities are arranged to protect environment from being polluted.

Description

A kind of environment friendly brick and preparation method thereof

Technical field:

The present invention relates to material of construction, specifically is a kind of environment friendly brick and preparation method thereof.

Background technology

Traditional brick is to be raw material with the clay, through brick press make adobe, dry, loading of kiln fires and forms.Along with development of science and technology, the raw material of brickmaking and the method for brickmaking have had many variations, mud environment protection brick, energy-saving environment protection brick, coal gangue environmental protection brick or the like have especially occurred.

Summary of the invention

The objective of the invention is to provide a kind of is the environmental protection brick of main raw material with rubbish, building roach, and this brick both can be turned waste into wealth rubbish, roach, can reduce refuse pollution again, and cost was low.

The object of the invention realizes by following technical proposals:

Environmental protection brick of the present invention is made up of following raw material and consumption weight percent:

Work in-process rubbish 40-50%

Building roach 40-50%

Cinder 3-8%

Coal ash 2-6%

Lime 1-3%.

Described work in-process rubbish be earlier can not brickmaking material screen after, again through the pulverizing material of crushing screening.

Described lime mainly plays disinfection.

The making method of environmental protection brick of the present invention comprises the steps:

1) batch mixes, Jia Shui stir into mud according to the above ratio;

2) with the mud fermentation, fermentation time is 20～40 days;

3) with the mud that ferments brick press brickmaking base, described adobe is atresia or porous;

4) with brick blank drying, drying time is 150～250 minutes;

5) adobe after will drying is fired through annular kiln, and firing temperature is 1400～1600 ℃, and the firing time is 20～30 hours.

Described oven dry is to utilize the waste heat of annular kiln to be transported to baking room by underground pipeline, the oven dry adobe, and the cigarette that produces when baking bricks is transported to the boiled water room water bath dust-removing through the current drainage underground pipeline.

Advantage of the present invention:

1) makes raw material with work in-process rubbish, can turn waste into wealth, reduce refuse pollution, for the protection environment is contributed;

2) protection clay resource;

3) save ground, hack, produce and be not subjected to the weather effect in season;

4) UTILIZATION OF VESIDUAL HEAT IN, energy-saving and emission-reduction;

5) be provided with dust-eliminating environment protecting facility, environmentally safe.

Embodiment

1, by following weight percent batching: work in-process rubbish 45%, building roach 45%, cinder 5%, coal ash 3.5%, lime 1.5%;

2, batch mixes is stirred into brick mud;

3, with brick mud fermentation 30 days;

4, with 500 type brick press brickmaking bases;

5, annular kiln waste heat oven dry;

6, the annular kiln base burns, and firing temperature is 1500 ℃, and the firing time is 24 hours, obtains the finished bricks that compressive resistance reaches 80-110.

Environmental protection brick of the present invention is pressed GB6566-2001 standard accredit through quality testing department.
