Description
Technical field
The present invention relates to building waste recycling field, more particularly to a kind of building waste recovery system.
Background technology
With industrialization, the acceleration of urbanization process, construction industry is also simultaneously fast-developing, the building waste produced together
Increasing, the quantity of Chinese architecture rubbish has accounted for more than the 1/3 of municipal refuse total amount.Specific building waste refers to build
If, unit in charge of construction or it is personal all kinds of buildings, structures etc. are built, removed, are repaired and resident's decorative house during
Produced remaining mud, recrement, mud and other discarded objects.According to origin classification, building waste can be divided into soil excavation, road and open
Dig, old building is removed, construction and the class of production of construction materials rubbish five, mainly by dregs, crushed stone, waste mortar, brick and tile fragment,
Concrete block, asphalt blocks, waste plastics, old metal material, useless bamboo wood etc. are constituted.
Many discarded objects in building waste are sorted, reject or crush after, mostly can be again sharp as regenerated resources
With such as：The metals such as steel scrap muscle, waste iron wire, waste electric wire and various steel scrap accessories, can for sand, for masonry mortar, motar,
Concrete cushion etc. is beaten, can be also used for making the building materials such as building block, Paving brickses, lattice brick.
In the recycling to building waste, generally require by broken, sieve, sieve, the flow such as wet concentration will be mixed
Building waste together is divided into relatively pure single material.
It is sharp again that such as Publication No. CN106145731A Chinese patent literature discloses a kind of and building waste recovery
With method, comprise the following steps：(1) by the waste concrete in building waste, barren rock material, waste ceramic, useless sintered brick and tile and sand-lime
Brick etc. is sorted by species, and granularity 00mm is crushed to respectively；(2) material after crushing is sieved, by the metal of smallclothes
Class material is selected, and the cleaning that added water in material, flotation sort out wood chip and working of plastics smallclothes；(3) after to screening and flotation
Material be crushed to granularity respectively less than 60mm through machinery again, available regeneration stone material is formed, for roadbed laying；(4)
The material after further crushing can be also ground to less than 5mm, form recycled fine aggregate, cement is made after conventional treatment.
Specifically in each operating procedure, also there are problems that material waste or operation.
For example in magnetic concentration working, the material of material transportation band transport mixing is by magnetic separation conveyer belt, by being arranged on magnetic
Select the strong electromagnet in conveyer belt that metal material can be adsorbed to magnetic separation conveyer belt.As magnetic separation conveyer belt is operated metal
When transport of materials is to non-strong electromagnet region, the pulling force that metal material loses magnetic force offer falls under gravity into magnetic separation sieve
Separate in hopper, complete magnetic separation.But before the material of mixing enters magnetic separation conveyer belt, the material of mixing may nothing in a jumble
Spacing between chapter, even above magnetic separation conveyer belt and material transportation band, so that wear and tear magnetic separation conveyer belt and material transportation band, very
To the conveyer belt operation of retardance material, magnetic concentration working is influenceed.
For example in flotation operation, light material and heavier feeds can be distinguished by the buoyancy of water body.Wherein lightweight
Material half is bulky foam material, by that can absorb larger moisture toward contact after wet concentration.Therefore needed in recycling
The material block more compacted is squeezed into by squeezing process.But squeezer of the prior art can usually be deposited in squeezing storehouse
At many dead angles, meeting stacking material during operation is squeezed.Therefore it is frequently necessary to artificial dredging.And flotation water is followed
Ring is utilized also has problem always.Mix organic and inorganic impurity in flotation water, it is necessary to which multi task process could meet circulation
Using requiring.
For example in screening operation, the lump material of mixing enters screen box, and the nearly rotation for crossing screen box throws away material centrifugation.
According to the size of the sieve aperture on the side wall of screen box, the material of different-diameter size can be screened out.But in order to which screening operation is needed
To be handled successively greatly from small beat, this allows for the maximum material of diameter will operate maximum duration in screen box.Operated in screen box
During, material can collide with the side wall of screen box, have a strong impact on the service life and precision of screen box.
