Description
Technical field
Building waste recycling field is the utility model is related to, more particularly to a kind of screening plant of building waste.
Background technology
With industrialization, the acceleration of urbanization process, construction industry is also simultaneously fast-developing, together caused building waste
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
Caused remaining mud, recrement, mud and other discarded objects.According to origin classification, building waste can be divided into soil excavation, road is opened
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. form.
Many discarded objects in building waste are sorted, reject or crush after, can be used as regenerated resources again sharp mostly
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, screening, screening, the flow such as wet concentration will mix
Building waste together is divided into relatively pure single material.
Such as to disclose a kind of and building waste recovery sharp again for Publication No. CN106145731A Chinese patent literature
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, is crushed to granularity 00mm respectively；(2) material after crushing is sieved, by the metal of smallclothes
Class material is selected, and in material plus water cleaning, flotation sort out wood chip and working of plastics smallclothes；(3) after to screening and flotation
Material be crushed to granularity respectively through machinery again and be less than 60mm, 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 screening, mixed material enters screen box, and the nearly rotation for crossing screen box throws away material centrifugation.According to screen box
Side wall on sieve aperture size, the material of different-diameter size can be screened out.But in order to which screening operation needs to beat from small
Handle successively greatly, this allows for the maximum material of diameter will operate maximum duration in screen box.During screen box operates, thing
Material can collide with the side wall of screen box, have a strong impact on the service life and precision of screen box.
