Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0026] The polishing waste residue recycling method of this embodiment, the present embodiment divides the polishing waste residue into foaming waste residue and non-foaming waste residue, said foaming waste residue refers to polishing waste residue containing resin, silicon carbide, magnesium chloride and other components; said non-foaming waste residue Foaming waste refers to polishing waste that does not contain resin, silicon carbide, magnesium chloride, etc., and non-foaming waste can be recycled by existing conventional treatment methods, which will not be explained in detail here;

[0027] The recycling of foaming waste slag described in the present embodiment comprises the following steps:

[0028] A. Settling, after the flocculant is added to the polishing waste water of the foaming waste r...

Abstract

The invention discloses a polishing waste slag recycling method which comprises the following steps: settling, screening, pressure filtration and utilizing, wherein the screening step comprises the process of sequentially passing the settled slurry through a 6-20-mesh screen, a 40-60-mesh screen and a 110-130-mesh screen. The polishing waste slag recycling facility comprises a polishing wastewater output tube, a flocculant output tube, a settling tank, filter screens, scrapers and a filter press. By using the polishing waste slag recycling method, the flocculant added into the settling tank accelerates the solid-liquid separation of the polishing wastewater; the settled slurry is subjected to layered screening, thereby enhancing the screening efficiency and avoiding the problem of screen blockage caused by the settled slurry; and the settled slurry is recycled for different purposes by different screening ways, thereby implementing the maximum-applicability reutilization on the waste.

Description

technical field [0001] The invention belongs to the technical field of architectural ceramics, and in particular relates to a method for recycling polishing waste slag and used equipment. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and the continuous rise of production costs, how to recycle waste and turn waste into treasure is an important issue in various industrial productions. [0003] In the production of polished tiles of architectural ceramics, since the fired ceramic tiles need to be polished and polished to form finished products, how to rationally recycle a large amount of solid sludge (hereinafter referred to as polishing waste) generated during the polishing process has always been an important issue. Technical problems urgently needed to be solved by technical personnel in the field. Polishing waste slag contains resin, silicon carbide, magnesium chloride and other components. When it is introd...
