Description
Technical field
The present invention relates to building waste processing technology fields, in particular, being related to a kind of mixed separation synthesis of building refuse brick
Disposing technique.
Background technique
Building waste refers to the solid waste generated in the newly-built of building, enlarging, finishing or demolishing process,
Such as: brick and tile, sandstone, concrete, dregs, mud and other wastes.According to the difference in the generation source of building waste, Ke Yifen
For construction building rubbish, tear Old building rubbish and finishing building waste open.With the continuous development of Building Trade in China, especially premises
The high speed development of industry is produced, the yield of the annual building waste in China accounts for the 30%-40% of municipal refuse total amount.
Currently, the disposal options of China's building waste mainly also rest on air storage or simple landfill, mode is more
Fall behind.With the iterative method of urbanization process, building waste yield increases year by year, and traditional disposal options not only cause huge
The big wasting of resources, disposing bad can also generate on environment such as surrounding soil, atmosphere, underground water centainly influences, and is unfavorable for resource
Economizing type, pro-environmental society.China's construction refuse resource level is not also high, and construction refuse resource rate is also very
Low, building waste reuse ratio is less than 5%, and compared to the building waste reuse ratio that developed country is more than 90%, there are still quite big
Gap.One of the main reason for generating this gap is exactly the weakness of building waste processing technique, is mixed in building waste
Brick is mixed with concrete, lacks corresponding isolation technics means, can only be as additional after being handled by crushing and screening
It is worth lower primary bed course to use.
To solve the above-mentioned problems, existing Chinese patent application publication No. is that the patent of 108237135 A of CN discloses
A kind of equipment of building waste pretreatment system, the patent include slat feeder, brick mix separation system, level-one crushing mechanism,
The system equipments such as two-stage crushing mechanism, Multilayer vibrating screen, wet type impurity removed system, automatic dustproof cover, wherein brick mixes separation system packet
Unit containing initial gross separation and jigging chamber can separate masonry with concrete, and pass through the screening that can be complementary to one another and break
Broken equipment is rationally combined, and using a large amount of dust-proof, removal of impurities devices, reduces environmental pollution, treating construction waste production
It is high-efficient.In addition, the patent that application publication number is 106378249 A of CN discloses a kind of building castoff mixed separation of brick twice
Building waste raw material is once sorted the following steps are included: the mixed sorting of a brick, obtains the first object by technique, the patent
Material, second material and third material；Sorting, i.e., sort first material, removes the sundries in first material；It is broken, i.e.,
First material after sorting is delivered to crusher to be crushed；Screening, i.e., be delivered to the first sieve for broken first material
Separating device is sieved, and dregs, first material and the first thin material are obtained；First thin material is delivered to by secondary sorting
One flotation unit carries out secondary sorting, obtains the material of brick and concrete material, in building castoff brick and concrete separate, can
The value utilized to the greatest extent using concrete regenerating improves the utility value of monolithic architecture waste.
But relative deficiency, the technique used in these types of patent are all the methods using gravity screening to building waste
The mixed separation of brick is carried out, the mixed separation degree of brick is limited, can only be using multiple when needing farthest to obtain brick and mixing separation of material
Broken, separating for several times method, high production cost, production efficiency is low, and economic benefit is low.Therefore, this requires a kind of new skill
Art solves the above problems.
Summary of the invention
The object of the present invention is to provide one kind can continuous production, high production efficiency, the building that production cost is low, easy to operate
The mixed separation joint disposal technique of brick made from waste, can by building waste masonry and concrete be kept completely separate, be conducive to masonry,
