Abstract

The invention relates to a sintered light-weight environment-friendly brick produced from printing and dyeing sludge and a manufacture method thereof. The sintered light-weight environment-friendly brick is characterized by being prepared by adopting printing and dyeing sludge, base waste sludge, furnace slag, refuse ash, calcium oxide, calcium sulfate, sodium carbonate, boric acid, ferrous sulfate, magnesium sulfate, Li macromolecular heavy metal trapping agent, water and the like as raw materials; and the manufacture method comprises the following steps of: mixing and stirring the raw materials in a biaxial mixer to be in a moisture state; extruding into rectangular bars by a vacuum sludge extruder; cutting and forming by a blank cutter; manufacturing light-weight environment-friendly brick blanks of printing and dyeing sludge under the pressure of 20-30 MPa; conveying the formed and naturally dried light-weight environment-friendly brick blanks into an annular kiln by a storage battery car to roast; and manufacturing light-weight environment-friendly brick products after roasting. Air laying bricks and pavement bricks in different specifications can also be manufactured from the raw materials of the invention, and the product has the advantages and the effects of light weight, great strength, zero pollution, low cost and good benefits.

Description

technical field [0001] The invention relates to a sintered lightweight environmental protection brick produced from printing and dyeing sludge.
