Description
Technical field
The invention belongs to construction material and resources circulation technical field, particularly to the production work of a kind of ecological dry-mixed mortar
Skill.
Background technology
Along with national economy stable development and the propelling of urbanization paces, building trade is fast-developing, construction
In journey, various mortar demands are also increased dramatically.Natural sand, as the primary raw material of preparation mortar, is a kind of non-renewable resources,
A large amount of exploitation heavy damage ecological environmenies.In recent years, along with the attention of Environmental protection, each place government formulates in succession
Limit the policies and regulations of natural sand exploitation so that natural sand market supply is not enough, holds at high price.
According to statistics, China produces building waste about 1,000,000,000 tons the most every year, and a large amount of building wastes stacked or fill are occupied
Soil, contaminant water soil resource and atmospheric environment, cause serious ecological load.Containing substantial amounts of construction waste in building waste
Sand, utilization rate is extremely low.Sand discarded in building waste is prepared reclaimed sand by reasonable process, is used for preparing ecological dry-mixed mortar,
Not only can alleviate the ambient pressure that building waste brings, the problem also solving the problem that dry-mixed mortar industry natural sand inadequate resource.
Summary of the invention
It is an object of the invention to provide the production technology of a kind of ecological dry-mixed mortar, building waste sorting obtained is useless
Abandoning sand material, sieving approach prepares reclaimed sand, uses reclaimed sand to substitute natural sand preparation varying strength etc. with the ratio of 30～50%
The ecology of level is built by laying bricks or stones, is plastered and ground dry-mixed mortar.
To achieve these goals, the technical solution used in the present invention is:
The production technology of a kind of ecological dry-mixed mortar, comprises the steps:
Step 1, prepared by reclaimed sand: construction waste sand material is finished product through bolting, minus mesh, and oversize is through disintegrating machine
Row screening again after Po Sui, until all by vibrosieve, minus mesh is prepared reclaimed sand；
Step 2, reclaimed sand drying: reclaimed sand drying equipment is dried, moisture content≤0.5%；
Step 3, natural sand drying: natural sand drying equipment is dried, moisture content≤0.5%；
Step 4, additive mixes: different additive blended equipment mix homogeneously, prepares mixing additive；
Step 5, the ecological dry-mixed mortar of preparation: by the natural sand dried, cement, flyash, regenerated fiber, the regeneration of drying
Sand, mixing additive are hybridly prepared into ecological dry-mixed mortar through mixing equipment in proportion.
In described step 1, construction waste sand material obtains in the following way:
By loader, building waste is fed apron feeder, and building waste is sent into separator by apron feeder, profit
Sand discarded in building waste, discarded clay brick, discarded concrete being separated by volumetric method, formation construction waste sand material, building are useless
Abandon clay brick material and three kinds of primary product of construction waste concrete material；Wherein, described construction waste sand material be mainly composed of useless
Abandon building mortar, also comprise broken clay fragment of brick and the concrete block of very small amount particle diameter≤40mm.
In described step 1, vibrosieve be screen size be the single-deck screen of 2.36mm.
In described step 1, also include, except ferrum, light materials separate and dust collecting process, before feed of crusher, being filled by magnetic separation
Putting and remove irony material and light materials with light materials sorting unit, the light materials sub-elected is by the standby regeneration of high-speed fibre release mechanism
Fiber, during sieving approach, by atomising device dedusting.
In described step 3, described additive is hydroxypropyl methyl cellulose and sodium lauryl sulphate, the consumption of each component
