Embodiment 1

[0044] Such as figure 1 and figure 2 As shown, the method for preparing composite colored silica sand for permeable bricks provided in this example includes first placing a variety of monochromatic silica sands in a stirring device for stirring and mixing. The stirring device has a rotatable horizontal mixing chamber 1 and does not have The stirring paddle, the inner wall of the horizontal mixing chamber 1 is provided with a number of stirring protrusions 2, thus stirring the mixed composite color silica sand, the surface of the silica sand particles is dense and smooth, and the water permeability of the permeable brick prepared from this composite color silica sand is comparable to that of a single color The permeable rate of permeable bricks made of silica sand is basically the same. This is due to the use of the horizontal mixing chamber 1 and the cancellation of the stirring paddle, which fully utilizes the advantages of horizontal stirring. With the help of the silica s...

Abstract

The invention relates to the technical field of water permeable brick preparation, in particular to a method and stirring device for preparation of composite colored silica sand used for water permeable bricks. The preparation method includes putting a variety of single color silica sand in the stirring device for mixing, the stirring device has a rotatable horizontal stirring bin and has no stirring paddle, the inner wall of the horizontal stirring bin is equipped with a plurality of stirring bulges, and the stirring method includes placing of the variety of single color silica sand in the stirring device for mixing. According to the method and stirring device for preparation of composite colored silica sand used for water permeable bricks provided by the invention, the prepared water permeable bricks have the characteristics of high water permeation rate and good water seepage effect.

Description

technical field [0001] The invention relates to the technical field of preparation of permeable bricks, in particular to a method and a stirring device for preparing composite colored silica sand for permeable bricks. Background technique [0002] With the gradual improvement of the "sponge city" concept, laying permeable pavement in the city, speeding up the water seepage rate of the pavement, reducing the water on the road, and even setting up a water storage space under the permeable pavement. Evaporating into the air through the road surface can provide a good regulating function for the city and become the first choice for new urban construction schemes. [0003] At present, when paving permeable pavement, permeable bricks with silica sand as the main material are mostly used. According to the color design requirements of the pavement, monochrome silica sand such as white, black, and yellow is common, and composite colors formed by mixing two or more monochrome silica s...
