Embodiment Construction

[0007] The present invention is realized by adopting the following technical solutions: the manufacturing method of the large-scale green brick, the size of the large-scale green brick is length × width × thickness = 4.2m × 2m × 1m; the raw materials and weight ratio used for the large-scale green brick are: clay 90 %, 0.5% of coal gangue powder, 7.5% of coal powder, 1% of coal slime, 0.5% of iron powder, and 0.5% of glass powder; There is a method of mixing mud with conventional size blue bricks; that is, select fine clay, turn over the soil and sieve to remove impurities, make the clay finely crushed and purified, pile the purified clay into a pile, beat the weir, soak water, and add ingredients such as coal gangue powder and coal slime , coal powder, iron powder, glass powder, and wet clay and turn it, add water and mix it into mud, simmer for 3-5 days, turn the mud and ribs again, and then make the billet; A mold with the size of a large blue brick is made into a mold with...

Abstract

The invention relates to a method for manufacturing black bricks, in particular to a method for manufacturing large-size black bricks, which solves the problem that the traditional baking process of black bricks in conventional sizes cannot manufacture large-size black bricks. Each large-size black brick respectively has the length, the width, and the height of 4.2 m, 2 m and 1 m, and the large-size black brick is made from the following raw materials in percentage by weight: 90 percent of clay, 0.5 percent of coal gangue powder, 7.5 percent of coal powder, 1 percent of coal slime, 0.5 percent of iron powder and 0.5 percent of glass powder. The manufacture process comprises the working procedures of kneading mud, making blanks, drying, loading the blanks into a kiln and roasting. During making the blanks, two fine iron wire nets are put among the brick blanks at intervals; during loading the blanks into the kiln, black bricks in the conventional sizes are palletized and clamped on the peripheries and the upper parts of the large-size black bricks; and during roasting, the brick blanks are roasted twice according to a roasting method of the black bricks in the conventional sizes. The large-size black bricks manufactured by the method have higher strength and no cracks and breakages and fully meet the requirement of brick carving.

Description

technical field [0001] The invention relates to a method for manufacturing green bricks, in particular to a method for manufacturing large-scale green bricks. Background technique [0002] In order to better inherit and develop the precious humanistic and artistic heritage in ancient buildings, and to make better use of brick carving techniques, large blue bricks are needed in practice. Due to the large size of large blue bricks, the existing firing process of conventional size blue bricks cannot meet the strength requirements of large blue bricks. Unable to meet the needs of brick carving. Contents of the invention [0003] The present invention provides a method for manufacturing large-scale green bricks in order to solve the problem that large-scale green bricks cannot be produced by the firing process of existing conventional-sized green bricks. [0004] The present invention is realized by adopting the following technical solutions: the manufacturing method of the l...
