Fig. 1 is a process flow sheet of the present invention.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
When existing building waste is pressed materials classification, building waste can be divided into metal species (iron and steel, copper, aluminium etc.) and non-metal kind (slag clay, crushed stone, waste mortar, brick and tile fragment, concrete blocks, asphalt blocks, plastic waste, useless bamboo wood etc.), but building operation rubbish and old building are removed the rubbish moiety and are differed bigger, in general, the refuse composition that accounts for more than 80% mainly contains: earth/dust, stone/rubble, concrete, fragment of brick, sand, pitch etc.; The refuse composition that accounts for less than 20% mainly contains: bamboo/timber, waste metal, other organism, plastics tubing, glass and other foreign material etc.
Utilize the technology of these rubbish for the raw material production environment friendly component, its building waste includes discarded metal, timber, waste plastic and base-material, described base-material is the sandstone brick, and its technical process is as follows: A, collection fragmentation: building waste is discarded to collect to deliver to carry out fragmentation in the crusher;
B, screening: the building waste after the fragmentation is put into the machine of screening, and this machine carries out building waste with metal, timber and waste plastic automatically and base-material is classified and the various article delivery that classification is come out are arrived specified stacking place;
C, stirring: deliver to after the base-material that screens measured out and force to stir after adding water in the stirrer;
D, batching: the base-material in stirring adds additive and stirs fully;
E, moulding: the mixed base-material that will stir is again delivered in the main frame of compression molding and is vibrated into needed shape;
F, will pass out in the laydown area at the building slab of vibration moulding in the main frame and place the regular hour and can finish.Wherein said base-material includes aggregate and fines, and described aggregate is exactly after fragmentation, and its particle is bigger, but base-material up to specification; Fines is exactly after fragmentation, those base-materials that its particle is smaller.
Above the fragmentation of described A step can be divided into one-level fragmentation, two-stage crushing and three grades of fragmentations, will carry out base-material after the one-level fragmentation and filter out a part of aggregate and a part of fines and those metals, timber and waste plastic are elected; The base-material that a part of in addition particle is bigger carries out two-stage crushing again, aggregate behind the two-stage crushing rescreens selects a part of aggregate and a part of fines, the base-material that a part of in addition particle is bigger carries out three grades of fragmentations again, some aggregate of base-material and a part of fines after three grades of fragmentations are delivered to measure in the gauger to deliver in the stirrer after the aggregate after the fragmentation and fines got up by 1: 1 mixed again and are stirred; In the present invention, also independent aggregate directly can be delivered in the gauger and be measured, independent fines directly can also be delivered in the gauger and be measured, described aggregate and fines can be used as raw material separately; Described additive is formed by cement and a spot of water glass colloid, and the ratio that described additive accounts for whole base-material weight is about 5%～10%; Base-material after the stirring is delivered to finished product laydown area borough chief's time at the building slab of vibration moulding in the main frame can obtain finished product after stacking, perhaps the building slab in vibration moulding in the main frame is sent in the curing kilns, be heated between 80 ℃～100 ℃ by water vapour in the curing kilns, after stacking the short period of time under this condition, can obtain finished product, the heat that is used for adding the hot steam of the present invention is to utilize the timber that screens after the one-level fragmentation to burn to get, described probably is seven day time for a long time, and the described short period of time probably is the time; Described metal is screened from timber and waste plastic is to select with a magnetic separation machinery, and this method is fast and make things convenient for.
Principle of the present invention is that cement hydrolysis in hydration process goes out that active ion (SiO2/Al2O3/CaO etc.) reacts again in Ca (OH) 2 and water glass colloid and the aggregate, generate calcium silicate hydrate and calcium aluminate hole with the gel form filler aggregate, strengthened the cohesive force of the storeroom of aggregate, gel further dewaters simultaneously, promoted the long-term growth of block strength, make cured article have weather resistance and stability preferably, theory and practice proves that its later strength constantly increases, work-ing life is generally also long than clay brick, so the present invention can also provide a kind of good composition brick outside the whereabouts problem that solves building waste.
