A kind of ceramic particle and the preparation method of non-fired permeable brick using same

Abstract

The invention discloses a ceramic particle and a preparation method of a baking-free water permeable brick using the ceramic particles. The method comprises the following preparation steps that 1, ball milling is performed: water is added into a ceramic brick waste material, ball milling is performed, and slurry is obtained; 2, the slurry is subjected to spraying granulation to obtain round powder materials with the particle diameter being 20 to 40 meshes; 3, sintering is performed: the round powder materials are sintered to obtain ceramic brick particles. The preparation method of the baking-free water permeable brick using the ceramic particles comprises the following steps of 1, blending: mixing the ceramic particles and bonding agents, and uniformly stirring the mixture to obtain a mixed raw material; 2, material distribution: distributing the mixed raw material blended in the first step into the mold, performing vibration, and then performing punching forming; 3, mold opening and product obtaining: opening the mold and obtaining the baking-free water permeable brick product.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a ceramic particle and a method for preparing a fire-free permeable brick using the same. Background technique [0002] Urban waterlogging disasters are becoming more and more serious. Building a water-absorbing "sponge city" that absorbs, stores, infiltrates, and purifies water when it rains, and "releases" the stored water when needed, has become a new generation of urban stormwater management. concept. [0003] At present, regardless of whether the permeable bricks are sintered or bonded with adhesives, the particle size of the barren particles used in them needs to be uniform, because only when the particles are approximately round and uniform in size can a better water permeability effect be obtained, but Although the currently used barren aggregates (such as stones) can achieve this feature, their waste is serious, because in the process of crushing ...

Problems solved by technology

[0003] At present, regardless of whether the permeable bricks are sintered or bonded with adhesives, the particle size of the barren particles used in them needs to be uniform, because only when the particles are approximately round and uniform in size can a better water permeability effect be obtained, but Although the currently used barren aggregates (such as stones) can achieve this feature, their waste is serious, because in the process of crushing and screening, there will be a large amount of finely divided powder that cannot be used (it will block the pores), and The barren granules obtained by crushing are mostly irregular in shape, so they also have certain deficiencies in water permeability

[0004] In addition, waste materials (such as waste powder, mud, clinker particles, etc.) generated during the production of ceramic tiles are difficult to handle, and are generally disposed of in landfills, which not only wastes resources but also saves energy. pollute water bodies
