Description
Technical field
Material Field is handed over the invention belongs to disposition of solid waste and road engineering, a kind of shell class salvage property is related generally to
Source turns to the process of road engineering material.
Background technology
The seafood shell class discarded objects, only China's Along Zhejiang Coast such as global annual generation millions of tons shell, shrimp shell, crab shell
Annual production is just more than 100,000 tons of discarded objects.A large amount of shell class discarded object abandoneds cause the pressure of sternness to environment in environment.
Containing compositions such as abundant calcium carbonate, chitin, protein in shell class discarded object, feed can be processed into, for making
The shell class such as medicine, papermaking, construction material, but the processing in these zone materials and use cost mistake by shell class changing rejected material to useful resource
Height, thus digestion shell class discarded object amount it is minimum, most shell class discarded objects can only abandoned in environment.
Road engineering has the features such as extensive, simple, raw material are less demanding all the time, shell class discarded object high content
The portion of material that the roadbed of calcium carbonate and field of road, basic unit and road surface are used, such as flyash, lime, miberal powder etc.
Main component is close.Therefore, develop a kind of processing cost it is low, can resource shell class discarded object be on a large scale road engineering material
Process, existing lasting environment protection significance, has certain economy concurrently again.
The content of the invention
It is an object of the invention to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of shell class waste material turns to road
Engineering material process, this shell class waste material turns to road engineering material process can be by the shell big rule of class discarded object
Mould resource turns to road engineering material, the features such as with economic, environmental protection.
In order to realize the object of the invention, the technical scheme that this law is taken is：
Shell class waste material turns to the process of road engineering material, and its feature is comprised the following steps：It is roughing, drying, broken
Broken, calcification, it is dehydrated and grinds.
Further, the roughing step is：One or more in roughing shell class discarded object.
Further, the drying steps are：First shell class discarded object is dried in the shade under ventilated environment, environment temperature of drying in the shade is
10-25 DEG C, time span is 10d-30d；Shell class discarded object is put into 100 DEG C of -200 DEG C of baking ovens afterwards continues to dry 1h-5h.
Further, the destruction step is：To be carried out stoving process operation shell class discarded object take out, and with rush
Hammer is broken into fragment, and fragment size distribution ranges are 0-10mm.
Further, the calcification step is：Shell class discarded object after will be broken pours into calcification pond, is added in calcification pond
The quick lime of shell class discarded object quality 10%-50%, mechanical agitation mixes the shell class discarded object and quick lime after crushing, stirring thoroughly
5min-30min, stirring is with degree 1r-5r/s；Then water, amount of water are added>65% Lime Quality, stirs 30-180min, stirs
Mix speed 1r-30r/s.
Further, the dehydration is：By be stirred it is broken after shell class discarded object, quick lime and water blend
Take out, the plane for drying, cleaning is laid in, in natural environment drying >=1d；Complete that blend is put into constant temperature after spontaneously drying
Drying and dehydrating 1h-24h in drying box, thermostatic box temperature is 50-100 DEG C.
Further, the step that grinds is：After completing dehydration, blend is transferred to grinder, grinds to form chi
It is very little<0.6mm powder body materials, the powder body material for being ground can be used for road engineering material.
The present invention has advantages below：
(1) shell class discarded object characteristic and road engineering material performance have been had concurrently：Shell class discarded object in addition to also having a large amount of calcium carbonate,
Also containing a certain proportion of free water, with reference to water, and the organic matter such as chitin, protein, on the one hand for stable curing shell
Active ingredient-the calcium carbonate of class discarded object, furthermore the ingredients calcium carbonate of solidification is met road engineering material performance requirement, this
The techniques such as invention is with drying in the shade, dry, quick lime heat of hydration high temperature and calcification stabilize and solidify the carbon in shell class discarded object
Sour calcium component, and the material for meeting field of road requirement specification is processed into using broken, grinding technics.
(2) it is economical：The deep process such as feed, medicine are processed into compared to by shell class discarded object, the processing of this technique is simple,
Low cost.
(3) environmental protection：Compared to other shell class changing rejected material to useful resource processes, present invention process method does not introduce any
Additional chemical reagent and chemical materials, the quick lime only applied are also conventional engineering material, in the absence of problem of environmental pollution.This
Outward, extensive resource shell class discarded object is road engineering material, and field of road can be also greatly decreased to natural mineral aggregate
Consumption, beneficial to environmental protection.
Specific embodiment
Embodiment 1
The process that this shell class waste material turns to road engineering material is comprised the following steps：Roughing, drying, broken, calcium
