Abstract
The invention discloses a comprehensive utilization method of solid waste-waste residue generated by stone processing. In stone processing, sawing, cutting and grinding can cause the generation of waste material, especially fine powder which causes severe pollution to the environment, such as local dust storm and water source pollution, and brings severe influence on the life and production of the local people. The method comprises the following steps: sorting and carrying out rough machining on the waste material to prepare cobblestones and sand for common building and road building; crushing powdery substance with air flow driven by a wind inflator and grading into fine powder with the diameter of less than 74 mum and fine powder with the diameter of less than 50 mum, and carrying out surface modification on the powdery substance with the diameter of less than 50 mum to prepare into high-quality paint, rubber, plastic, and filling material for papermaking industry. The method is a good method which reduces solid waste-waste residue pollution of stone processing enterprises and makes waste profitable.
Description
Technical field
The present invention relates to a kind of technical field of industrial solid castoff comprehensive utilization, refer to the processing of stone solid waste especially---the comprehensive utilization of waste residue.
Background technology
In the processing of stone process, saw blade, cutting, abrasive disc process all produce a large amount of solid waste-waste residues.Along with the stone material industry is constantly developed, the place of production is also more and more concentrated, and pile up like a mountain for the discarded object that is produced, and has not only occupied a large amount of soils, and dust pollution and to the contaminated water source life of affect people's seriously.Restricting the sustainable economic development of this area simultaneously.Administer the important measures of polluting, optimizing the environment, economizing on resources and being the sustainable economic development of processing of stone area of concentration, transforming mode of economic growth.
Summary of the invention
The objective of the invention is the solid waste with processing of stone---waste residue,, process the stone and the sand of the common building and the usefulness of building the road through sorting and roughing; The airflow milling that flour uses the wind-force air compressor machine to drive broken and be classified to straight warp less than 74um with straight through less than the fine powder of 50um; Diameter directly is used as the common fillers of coating, rubber, plastics, paper industry less than the fine powder of 74um; And diameter is less than the flour of 50um; Through the surface modification of the epoxy silane coupling of high-quality, process coating, rubber, the plastics of high-quality, the senior filler of paper industry; And be the environment that master's powder can use erosion resistant (like acid, alkali) with the granite composition.
To achieve these goals, technical solution of the present invention is: the first step is broken with crocodile formula pulverizer with big lump waste materials, directly through the sieve of 5mm the stone material screen is gone out with sieve aperture, and the stone that sifts out can be used for building and builds the road; Second step directly sifted out sand through the sieve of 0.5mm with sieve aperture, and the sand that sifts out also can be used for building and builds the road; The 3rd step, less than the 0.5mm powder, with airflow milling fragmentation and classification that the wind-force air compressor machine drives, the diameter that obtains was sold to coating, rubber, plastics, paper industry less than the powder packaging of 74um as common fillers with residual diameter; Diameter uses epoxy silane coupling to carry out surface modification less than the trickle part of 50um, processes the filler of high-quality, is used for coating, rubber, plastics, paper industry; With granite is main material end filler, and wear-resisting, decay resistance then is far superior to precipitated calcium carbonate and powdered whiting, and is available as wear-resisting, corrosion resistant senior filler.
The practical implementation method:
1, stone manufacturing: big lump waste materials is broken with crocodile formula pulverizer, directly stone is sifted out with sieve aperture and to get final product through the sieve of 5mm;
2, sand sorting: with above-mentioned collect screenings and waste stone dust with the sieve of aperture 0.5mm sand is sifted out, both can be used for building and built the road;
3, the processing of fine powder: will screen out the screenings behind the sand, and, obtain diameter less than the fine powder of 74um and diameter micro mist less than 50um with airflow milling fragmentation and the classification that the wind-force air compressor machine drives; Diameter is directly packed less than the fine powder of 74um, can be as the common fillers of coating, rubber, plastics, paper industry;
4, micro mist surface modification: above-mentioned diameter can pass through surface modification less than the micro mist of 50um, produces wear-resisting, the corrosion-resistant filling of high-grade coating, rubber, plastics, paper industry.
The method of surface modification is following:
In the 1000L tank diameter; Add entry 500L; Under agitation add epoxy silane coupling 5kg; And stir; Continuation adds the barren rock micro mist 100kg-200kg of diameter less than 50um under high-speed stirred; After stirring, with slurry thing oven dry or dry with industrial microwave oven, dried differential shape thing is finished product very.
Present processing of stone overwhelming majority position granite are so fillers such as the fine particle calcium carbonate that the trickle powder of its manufacturing is used always, coarse whiting have better wear-resisting, decay resistance.
Used the surface modifier of premium properties; Make filler and coating binder, rubber, plastics etc. that better compatibility arranged, improved properties of product, use epoxy silane coupling; Make such filler both can be used for solvent-based system, also can prolong simultaneously and be used for water-based system.
The above; Practical ways only is that preferred implementation of the present invention is described; Be not that scope of the present invention is limited; Under the prerequisite of the spirit that does not break away from technology of the present invention; Various distortion and improvement that this area engineers and technicians make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
