Further, be provided with the moisture automatic regulating apparatus in the described mixing roll.
The utlity model has following advantage: this system simple and reasonable, help adopting cement solidification technology and adopt high-molecular chelating agent the capable curing of flying dust, stabilization processes, the ability of handling flying dust is strong, so that landfill, prevent the flying dust contaminated environment, particularly prevent the pollution of flying dust, environmental protection to air.
Description of drawings
Fig. 1 is the system flow chart of the utility model embodiment.
The specific embodiment
With reference to figure 1, a kind of flyash curing stabilizing treatment system is characterized in that: comprise flying dust warehouse, cement warehouse and mixing roll, described flying dust warehouse is given through a batcher and is expected the flying dust bucket; Described cement warehouse is given through another batcher and is expected the cement bucket; Described flying dust bucket and cement bucket are arranged on the charging aperture top of mixing roll, and the charging aperture top of described mixing roll also is provided with the chelating agent bucket.
In the present embodiment, the discharging opening of above-mentioned mixing roll below is provided with the maintenance conveyer, and above-mentioned maintenance conveyer below is provided with haulage vehicle; Above-mentioned flying dust bucket and cement bucket are by PLC control material level separately; The charging aperture of above-mentioned mixing roll is provided with material detector; Be provided with the moisture automatic regulating apparatus in the above-mentioned mixing roll.
In the present embodiment, above-mentioned flying dust warehouse can a conveying worm be fed to the flying dust bucket through a batcher to expecting earlier again; Described cement warehouse another conveying worm is fed to the cement bucket through another batcher to expecting earlier again, and above-mentioned batcher can be a star-shaped feeding machine etc.
With reference to figure 1, system of the present utility model mainly comprises five unit, is respectively flying dust feed unit, cement feed unit, stabilization processes unit, instrument air element and maintenance unit, and the concrete processing step of handling is as follows.
(1) by the star-shaped feeding machine under the flying dust warehouse and conveying worm quantitatively to the quantitative flying dust of flying dust bucket supply, meanwhile star-shaped feeding machine under the cement warehouse and conveying worm provide quantitative cement to the cement bucket simultaneously, wherein the star-shaped feeding machine of cement warehouse has the delayed startup regulatory function, so that adjust flying dust and quantitatively mixing simultaneously of cement.
(2) flying dust bucket and cement bucket are controlled by PLC, when material reaches material level, close flying dust, cement batcher, simultaneously to the mixing roll feed.
(3) when material detector detected material arrival mixing roll, the mixing roll startup mixed material.
(4) while chelating agent mixed solution sprays into mixing roll with the pressure of 1.5MPa, the moisture automatic regulating apparatus is by monitoring the addition that material characteristic is adjusted chelating agent and water in real time, flying dust, chelating agent, cement mix in mixing roll, heavy metal class in the flying dust and chelating agent generation complex reaction, thus it is stabilized to generate water-fast material.
(5) drop on the maintenance conveyer through the material of mixing roll after mixing, fall into the haulage vehicle under the maintenance conveyer afterwards, corresponding laydown area was stacked maintenance and is got 10 groups of specimen and carry out assay in haulage vehicle was transported in the factory flying dust between the discharging storage, through 48 hours stacking assays and draw the whole qualified backs of 10 groups of samples and flying dust is transported to landfill factory landfill by haulage vehicle, if do not reach the security requirement of stabilizing fly ash thing, should take the proper extension curing time; If any one group of sample leaches the defective then material that whole day is handled of toxicity monitoring and transports mixing roll back and handle again in 10 groups of samples.
Need to prove that especially some inessential contents and prior art content among Fig. 1 do not repeat them here.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
