Abstract
The present invention relates to a method for treating inorganic solid waste materials and an application of inorganic solid waste materials. The method comprises the following steps: waste silicon, waste concrete blocks, coal gangue and blast-furnace slag are used as solid waste materials to be primarily separated and then are respectively crushed into removing impurities whose granularity is smaller than 400mm; all the coarsely crushed raw materials are respectively and finely crushed into materials whose granularity is smaller than 80mm to form regenerated aggregate; then the formed regenerated aggregate is divided into regenerated aggregate with the granularity of 80 to 60mm, 60 to 40mm, 40 to 20mm, 20 to 5mm and 5 to 0mm; all kinds of separated regenerated aggregate with each level of granularity are magnetically separated, washed and floated, impurities are removed, and regenerated aggregate with high quality can be obtained. Inorganic solid waste materials can be mixed with lime or cement and fly ash to be stirred into road bed materials and can also be mixed with cement, fly ash, sand and water to be stirred into concrete by the treatment method. The present invention has the advantages of high quality, stable performance and high productive efficiency.
Description
Technical field
The present invention relates to a kind of processing method that caking shape offal treatments such as building waste, barren rock piece, gangue, blast-furnace cinder become regrown material that is used for.
The invention still further relates to the application of the regrown material that is used to be processed into.
Background technology
Along with the development of urban construction, the building waste that the removal of urban architecture is discharged is increasing, and not only land occupation, contaminated environment have also caused the wasting of resources.Therefore, for addressing this problem, be that CN1298772A discloses a kind of processing of building waste and the patent of invention of regeneration method as the Chinese patent publication number.Its processing procedure is by after manually will give up brick and the sorting of waste concrete piece, is crushed to granularity respectively less than 200mm, and impurity such as metal object, wooden unit are rejected; Be crushed to granularity respectively less than 60mm through machinery again, form available regeneration stone material; The stone material of will regenerating mixes formation and changes underfill material and roadbed material with sand and lime, flyash; Mix with cement, sand and form new concrete material by the regeneration stone.This technology efficiently solves regenerated utilization of building waste, and takies a large amount of arable lands and environmental pollution problems.But also exist certain defective, as adopting technologies such as artificial separation, particle size after cracking, rejecting impurity, it is low to exist the efficiency of separation, once rejects the combined aggregate that impurity is handled, and only makes low quality finished product material or low grade regeneration concrete.
Summary of the invention
The objective of the invention is for solving the problem of above-mentioned existence, and a kind of processing method of inoganic solids discarded object is provided, thereby further improve the treatment process condition of discarded object, the high-quality regeneration aggregate after it is handled.
Another object of the present invention has provided the application of the regrown material of this processing, makes it can form high-quality roadbed material or concrete.
For achieving the above object, the technical solution that the present invention taked is finished by following measure: a kind of processing method of inoganic solids discarded object, it is to utilize solid waste such as useless brick, waste concrete piece, gangue, blast-furnace cinder to be base-material, its method is: will the give up solid waste of brick, waste concrete piece, gangue, blast-furnace cinder of a is carried out primary election, and coarse crushing forms the raw material of granularity less than 400mm respectively, preliminary metal object or timber impurity of rejecting wherein; B is each raw material of above-mentioned coarse crushing, carry out respectively fine crushing to granularity less than 80mm, form regeneration aggregate; C sub-elects the regeneration aggregate that grade is 80-60mm, 60-40mm, 40-20mm, 20-5mm, 5-0mm with the regeneration aggregate of above-mentioned fine crushing; D carries out magnetic separation, flushing, flotation with the regeneration aggregate of above-mentioned each sorting, rejects impurity, forms the high-quality regeneration aggregate,
Technical scheme of the present invention also comprises: described regeneration aggregate through flushing, the clay content after its flushing is less than 1%.Described regeneration aggregate through magnetic separation, the iron-holder after its magnetic separation is less than 1 ‰.The floating regeneration aggregate of washing of described warp, the timber impurity after its flotation is less than 1 ‰.
In the above-mentioned processing method through in small, broken bits to granularity less than the regeneration aggregate that 80mm forms, can be used for course, also can utilize it to mix lime (or cement), its weight ratio of flyash is that 5: 1: 3 mixs become compound to make roadbed material;
Select the regeneration aggregate of 80-60mm, 60-40mm, 40-20mm, 20-5mm, six grades of 5-0mm in the above-mentioned processing method through screening, can select two grade aggregates of 40-20mm, 20-5mm wherein, mix cement, flyash, sand, water, its weight ratio is 4.2: 1-0.7: 0-0.3: 1.8-0.8: 0.5 mix becomes concrete; Other grade aggregate also can mix lime or cement, the flyash mix becomes compound to do roadbed material.
The present invention makes its building material that obtains regeneration by building waste is handled, through mixing the structure material that different batchings can obtain different purposes.Form regeneration concrete, reach intensity, workability, frost resistance, the impermeability of regulation performance, can obtain according to the intensity difference: C5, C10, C15, C20, C25 regeneration concrete; Can obtain the normal concrete of the pump concrete of the high slump (160-220mm), the middle slump (40-160mm) and low slump (≤40mm) no slump concrete according to slump difference.Therefore, through the aggregate that this processing method obtains, make have the quality height, stable performance, structure material that production efficiency is high.
The specific embodiment
Below in conjunction with embodiment, the present invention is further described.
Its processing method is as follows:
A, building wastes such as its useless brick, waste concrete piece, gangue, blast-furnace cinder are carried out preliminary sorting, use vibration hammer or crane hammer with the armored concrete bulk respectively coarse crushing to granularity less than below the 400mm, it is standby tentatively to reject impurity such as reinforcing bar, timber;
B, with each raw material of above-mentioned coarse crushing, adopt loading machine pack into heavy-duty plate feeder with its send into disintegrating machine carry out fine crushing to granularity less than below the 80mm, it is standby to form regeneration aggregate;
