The patent document whose application number is 2010101171324 discloses a method for producing glass-ceramic by using the sludge of polished bricks, and the patent document whose application number is 011076860 discloses a method for producing ceramsite by using the waste mud of polished bricks, and the application number is 2004100790209 The patent document discloses a method of using polishing waste to produce ceramic tiles. The patent document with application number 101186519 discloses a porous ceramic material and its preparation method. Due to the limitations of these product characteristics, the output of the product is limited, and it is difficult to digest polished tiles. Due to the huge amount of solid waste produced in production, zero discharge of polishing waste cannot be implemented, and the quality of the obtained products is unstable

Embodiment Construction
[0016] The invention discloses a method for recycling polishing waste slag to be used in the production of polished tiles. It divides the polishing waste slag into two parts according to whether it contains resin, silicon carbide, and magnesium chloride. It is non-foaming waste residue; the sewage containing foaming waste residue is recovered by the existing sewage treatment method, and the obtained waste residue is used as foaming decoration in the polished brick fabric; the sewage containing non-foaming waste residue is treated by multi-stage precipitation method Sludge recycling treatment, the obtained particles above 100 mesh have low whiteness and are directly recycled as the base material of polished tiles, and the particles below 100 mesh are directly recycled and used as the surface of polished tiles due to their high whiteness. In the process of multi-stage sedimentation sludge recovery and treatment, the sewage is first passed into the first-level or first-level and s...

The invention discloses a method and a device for producing polished tiles by recycling polished waste residue, which is characterized in that the polished waste water is divided into sewage with foamed waste residue and sewage without foamed waste residue, the sewage with foamed waste residue and sewage without foamed waste residue are respectively performed a single processing, recovering and using; the sewage without foamed waste residue is carried out fine processing by using a multistage deposition method. The particles with greater than 100 meshes are directly recovered and used for a bottom material of the polished tiles, the particles with lower than 100 meshes are directly recovered and used for a surface material of the polished tiles, the obtained foamed waste residue is used for foaming effect of the polished tiles surface material, so that the polished waste residue enables hundred-percent stable reuse and realizes the zero discharge of polished waste residue.
Description
technical field [0001] The invention relates to the technical field of polishing brick production, in particular to a polishing brick waste slag recycling technology and automatic recovery equipment. Background technique [0002] In the existing production process of polished tiles, a large amount of solid waste will be produced, among which waste sludge, waste billet, and waste powder can be fully recycled through mature recycling technologies and processes. The polishing stage produces a large amount of waste residue, including rough grinding, scraping, rough polishing, fine polishing, fine grinding, chamfering and other processes. The waste residue produced by the rough polishing and fine polishing process contains resin, silicon carbide, When ingredients such as magnesium chloride are introduced into the production formula of polished tiles, defects such as body expansion, porosity, and deformation will occur during the firing process, so it is difficult to directly recy...
