Description
Technical field
The utility model relates to the comprehensive utilization of resources technical field, is specifically related to a kind of building waste combination of extrusion innocuity disposal system.
Background technology
China's building waste harmless treatment is not simple building stones fragmentation.China's building construction rubbish processing to be harmless relates to stripping metal thing, combustible, earth three big problems, and the harmless treatment of decoration building waste is just more complicated.Practice shows that China's made from construction refuse resource is handled, and at first will solve harmless treatment.China's building waste harmless treatment need constitute characteristics and building waste residue recycling treatment needs according to China's building waste, develops suitable harmless treatment equipment and technology.
Building material sand, stone, powder, about 10% is used for roadbed material, and 90% will be converted into various concrete base material products such as cement, concrete, mortar, plate brick.The made from construction refuse resource industry development is processed into the regrown material that can be used in the concrete base material products to building waste and is seemed important day by day.The regrown material that the concrete base material products uses should not contain metal object, combustible for example wood chip or fabric, earth, and promptly metal object, combustible, earth are the harmful substances in the regrown material.Building waste is processed into the regrown material that suitable cement based building materials use, and the building waste harmless treatment is the basis.
At present, China's made from construction refuse resource is handled and is utilized business processes brick masonry structure building building waste again, substantially do not realize building waste harmless treatment and pureization processing, contain a certain amount of earth in the reclaimed sand that deals, contain foreign material such as a certain amount of wood chip in the regeneration aggregate that deals, cause the regrown material user to hang back.
Flourish along with China's made from construction refuse resource industry, building waste are disposed and are handled direction towards scale and develop.The building waste scale is handled, and needs two-part, two-step method to realize resource, commercialization processing usually, i.e. building waste harmless treatment and made from construction refuse resource, commercialization are handled.The key of building waste harmless treatment is to solve foreign material to separate, and the key that made from construction refuse resource, commercialization are handled is to solve separating of raw material and " grog ".The core that building waste is handled is an isolation technics, and it is again key technology that wherein broken grinding process is selected, and is related to the science separation that building waste is handled.Facts have proved, use traditional jaw building stones fragmentation Wiring technology broken, that strike back broken and screening machine composition to handle brick mixed building rubbish, have problems such as the building waste disposal ability is low, processing is clean, the regrown material adaptive surface is narrow.
The main architecture structure form in countries in the world has timber structure, post and panel structure, brick mix structure, xoncrete structure etc.Each national building structure difference, construction material also is not quite similar.The building waste composition constitutes different, and building waste treatment facility and treatment process also are not quite similar.Firmly build portion's political affairs center of grinding according to China and announce that before the year two thousand thirty, the old building of 20,000,000,000 square meters will be removed by China.These old buildings are the brick-and-concrete buildings that eighties of last century was built before the nineties mostly, and a spot of is that xoncrete structure is built.The building waste that is Future in China discharging in 20 years is the brick-and-concrete buildings rubbish that fired brick and concrete constitute mostly.China's brick-and-concrete buildings rubbish characteristics are that tiny reinforcing bar is more, and lightweight combustibles such as wooden unit, fabric are more, and earth is more.Realize made from construction refuse resource, will separate above-mentioned three specific admixture things exactly, realize harmless treatment, prepare qualified building waste residue.
Eighties of last century is before the nineties, China's economy is flourishing inadequately, institute's room steel using amount that builds a house is less, and an outstanding feature is that pre-stress floor, lintel prefabricated board are that the use of fine steel rib concrete slab is popularized, and tiny reinforcing bar uses more in pre-stress floor and the lintel.The rejecting of these tiny reinforcing bars is the specific questions that exist in China's made from construction refuse resource processing procedure.Long, bar reinforcement because value is bigger, just reclaim after commercial jump bit is peeled off concrete by removing at the scene of removing usually then and there, and tiny reinforcing bar can't be peeled off recovery at the construction field (site) usually.
The building waste harmless treatment is exactly the building waste preliminary treatment, prepare exactly and meet the raw material that made from construction refuse resource regeneration is handled, promptly building waste is processed into that can to satisfy next procedure be that regeneration aggregate, reclaimed sand, regeneration powder are produced needed building waste residue raw material.Be the building waste harmless treatment, should satisfy big member construction waste crushing, satisfy primary structural component reinforcing bar and concrete again and peel off, isolate impurityes such as wooden unit, earth simultaneously again.Be the building waste harmless treatment, should satisfy coarse crushing, in broken, satisfy impurityes such as reinforcing bar and wooden unit, earth again and separate.
China's made from construction refuse resource is handled and is utilized enterprise more at present, is mostly to adopt the broken Wiring technology of traditional jaw building stones broken and the broken combination of counterattack to handle building waste.Tradition jaw broken and the broken building stones of counterattack suitable suitable broken building stones of broken toe-in or broken plain concrete, but handling brick mixed building rubbish often can not satisfy the demand.Adopt jaw problem broken and that brick mixed building rubbish is handled in the broken combination of counterattack to be: first, jaw is broken to be that one one of " crocodile mouth " formula is closed intermittent attrition crushing, tiny reinforcing bar can not thoroughly separate with concrete, pre-stress floor concrete discontinuous after the fragmentation wrapping up in reinforcing bar, magnetic plant is difficult to absorption, magneticly elects and wrapping up in concrete tiny reinforcing bar, and is wrapping up in concrete fine steel rib by what the manual sorting came out, needs artificial the hammering peel off concrete, very trouble, and inefficiency.Be that the broken attrition crushing of one-level jaw is difficult to make tiny reinforcing bar and concrete thoroughly to be peeled off.Second, the broken impact grinder that belongs to high speed rotor impact, interior lining panel counterattack of counterattack, so contain tiny long reinforcing bar in the taboo material, because tiny long reinforcing bar can twine rotor or bar reinforcement can block rotor, simultaneously, the broken concrete of high speed rotor rotated repeated stock, brick also are broken into chip to wooden, fabric, separate thereby cause the lightweight combustible to be difficult to letter sorting.Made from construction refuse resource is handled, because reinforcing bar can cause shutdowns of getting stuck of next procedure equipment, reinforcing bar separates the whether clean natural labor that relates to the made from construction refuse resource deep processing equipment, and whether the impurity separation totally relates to the regrown material quality.
To sum up analyze, China will realize made from construction refuse resource, need develop suitable treatment process and equipment according to China's building waste characteristics.
Through patented technology retrieval, there is not the building waste combination of extrusion harmless treatment patent documentation of being correlated with.

Embodiment 3
Building waste combination of extrusion innocuity disposal system is used for handling the decoration building waste
As shown in Figure 1, the difference of present embodiment and embodiment 1 is that described secondary attrition crushing equipment 5 is matsurface oppositely rolling roller crushers.
Described roller bearing separates conveyer 6 to be handled when decorateing building waste, and roller gap is adjusted to 10-15mm, is used for building slag and separates with the lightweight combustible.
When described system handles is decorate building waste, be provided with charging gear between one-level foreign material Sorting ﹠ Picking System 3 and the secondary attrition crushing equipment 5, described charging gear is a rod formula charging gear, and described rod gap is 50mm.
In the described processing decoration building waste combination of extrusion method for innocent treatment, the decoration building waste carries out the one-level attrition crushing with one-level attrition crushing equipment 1, brickbat, gravel-concrete are crushed to granule, and wooden unit, fabric be crushed, and the manual sorting goes out the electric wire that should not act as a fuel, plastics etc. on the one-level foreign material Sorting ﹠ Picking System 3; On secondary attrition crushing equipment 5 tops charging gear is set, this charging gear is the rod formula, the rod gap is 50mm, after entering charging gear by one-level foreign material Sorting ﹠ Picking System 3, the material less than 50mm of one-level attrition crushing equipment 1 output falls into 5 fragmentations of secondary attrition crushing equipment, the material greater than 50mm of one-level attrition crushing equipment 1 output enters collection bucket by charging gear, being the granule based on brickbat, gravel-concrete less than the material of 50mm, is material based on combustibles such as wooden units greater than the material of 50mm.
The compound of secondary attrition crushing equipment 5 enters cage drum sieve and isolates and build slag and combustible, builds slag and can be used as light partition wall production of articles raw materials such as regeneration brick, building block, has characteristics such as light weight, intensity height.Combustible can be compressed into cubic block and regard fuel use etc.Enter the combustibles such as wooden unit of collection bucket, can directly pack, compress the use that acts as a fuel, perhaps be broken into chip again, isolate through rotary screen and recompress into uses such as cubic block acts as a fuel after building slag.
The harmless treatment of decoration building waste, adopt the technical solution of the utility model, because brickbat, gravel-concrete belong to fragile material, combustible such as wooden unit, fabric belongs to flexible material, so brickbat, gravel-concrete be basically by the roll-in fragmentation, and wooden unit, fabric can be flattened by roll-in and do not have overbreak.
Present embodiment can solve each big and medium-sized cities decoration building waste harmless treatment problem.Decoration building waste characteristics are broken, little, and composition is more complicated.Decoration building waste brickbat and gravel-concrete remain leading composition, and weight ratio is brickbat, gravel-concrete more than 90%, but combustibles such as wooden unit, fabric are obviously more than building construction rubbish.So remaining, decoration made from construction refuse resource direction obtains brickbat, gravel-concrete waste residue.The combustible calorific value that separates is higher, can be used as manufacture of cement fuel or uses as house refuse power plant combustible energy and material.Relevant achievement in research shows, the combustible that China's decoration building waste is peeled off out, and the avirulence basically of burning suits to use as manufacture of cement fuel or as house refuse power plant combustible energy and material.
