Required concrete, concrete product is obtained using roller, wallboard production line, then will be described mixed
Solidifying soil product feeding maintenance bin is conserved to finished product, and the finished product is put to product stockyard.
As an embodiment, second fine aggregate and the fine powder are fed directly to sand
Workshop is starched, its moisture is dried to less than 0.5% by horizontal drying machine, coordinates cement
Corresponding dry method premixing mortar is produced into premixing mortar production line, mortar silo is sent into by elevator.
Compared with prior art, building castoff regeneration technique of the invention solves building
The contradictory problems of rubbish, turn waste into wealth simultaneously, realize that construction refuse resource is recycled, meet
Country is on developing a circular economy, the policy of environmental protection.
Embodiment
With reference to embodiment, the present invention is further illustrated.
The embodiment of building castoff regeneration technique of the present invention, comprises the following steps：
S1, pretreatment building waste, the building waste by pretreatment is packed with forklift pushing and sent
Enter mixing bunker and carry out preliminary screening, obtain the first primary finished product.Wherein, to the pre- of building waste
Processing, can be artificial or machine preliminary selection, by the metal material of bulk, wood materials,
Plastic material, paper scrap and glass etc. are separated and classified；Being beaten using forklift pushing will pass through
The building waste homogeneity of pretreatment, is easy to subsequent treatment；
S2, the primary finished product of preliminary treatment first, the first primary finished product is transported to by forklift and shaken
Dynamic dispenser, aggregate workshop is delivered to after except iron by belt, vibratory sieve again；
S3, the primary finished product of deep processing first, the first primary finished product Jing Guo preliminary treatment is entered
Row aggregate deep processing, obtains coarse aggregate, fine aggregate and fine powder.Obtain the bone of different thicknesses
Material can carry out classified use, expand the regeneration scope of building castoff, can such as supply
The use of concrete product, premixing mortar etc..
The building castoff regeneration technique solves the contradictory problems of building waste, same to time-varying
Waste be changed into values, realize construction refuse resource recycle, meet country on developing a circular economy,
The policy of environmental protection.
Wherein, the step of carrying out aggregate deep processing to the first primary finished product includes：
S31, broken first primary finished product simultaneously carry out preliminary screening, obtain loess, primary dcreening operation mixing
Thing.Wherein, the loess that preliminary screening is obtained can provide afforestation soil；
S32, impurity separation and postsearch screening are carried out to primary dcreening operation mixture, impurity separation includes use
Tramp iron separator separates metal object, and postsearch screening includes obtaining thick with the sifter screening of different pore size
Aggregate, fine aggregate；Fine powder is obtained by selection by winnowing simultaneously during postsearch screening.
Preferably, the particle diameter of coarse aggregate is 5-31.5mm, and part of coarse aggregates is screened by three times
To the second coarse aggregate that particle diameter is 5-10mm；The particle diameter of fine aggregate is 1-5mm, the thin bone in part
Material obtains the second fine aggregate that particle diameter is 1-2.5mm by sand making machine.
It is as one embodiment, coarse aggregate, the second coarse aggregate, fine aggregate and fine powder is direct
Concrete product workshop is delivered to, is mixed and stirred into mixing plant and obtains required concrete, is utilized
