Abstract

The invention relates to a sintered light environmentally-friendly brick produced from ceramic waste residues and silt and a manufacturing method thereof. The method is characterized by comprising the following steps of: mixing the ceramic waste residues, the silt, fly ash, garbage ash residues, marble waste residues, calcium sulfate, boric acid, sodium borate, ferrous sulfate, magnesium sulfate, a Li high molecular heavy metal collector and water serving as raw materials; stirring by using a double-shaft stirrer; extruding by using a de-airing extruder after the raw materials are wet; cutting and forming by using a blank cutter; manufacturing a light environmentally-friendly brick blank of the ceramic waste residues and the silt under the pressure of between 20 and 30Mpa; and feeding the formed and naturally dried light environmentally-friendly brick blank into an annular kiln by using a battery truck for baking to prepare a light environmentally-friendly brick product of the ceramic waste residues and the silt. The raw materials can also be used for preparing hollow blocks and pedestrian road bricks of different specifications; and the product has the advantages of light weight, high strength, no pollution, low cost and good benefit.

Description

technical field [0001] The present invention relates to a kind of sintered light-weight environment-friendly brick produced from ceramic waste slag and silt. Specifically, it is produced by using dehydrated dry powder of ceramic waste slag and silt produced when cleaning rivers, canals and lakes as main raw materials. A sintered lightweight environmental protection brick belongs to the field of waste treatment. [0002] The invention also relates to a manufacturing method of the sintered lightweight environmental protection brick. Background technique [0003] Ceramic waste slag is the damaged blank produced by the ceramic factory in the process of producing porcelain, the damaged waste that has not been calcined and glazed, the semi-finished product that has been calcined and glazed in the factory, the waste product due to damage or cracks, and the waste building ceramics from the construction site. , waste sanitary ceramics and other places where ceramics are used, and wa...
