Description of drawings
Fig. 1 is the structural representation of production system of a kind of construction refuse regenerated adulterant of the utility model.
Embodiment
As shown in Figure 1; The production system of this construction refuse regenerated adulterant; Comprise: sand washer 1, crusher 2, lift 3, feed bin 4, feeding machine 5, micronizer main frame 6, powder collector 7, fly-ash separator 8, air compressor machine 9, blower fan 10, an outlet of said sand washer 1 is connected with the inlet of said crusher 2, and another outlet of said sand washer 1 and the outlet of said crusher 2 are connected with the inlet of lift 3; The outlet of said lift 3 links to each other with said feed bin 4; The inlet of said feeding machine 5 is connected with said feed bin 4, and the outlet of said feeding machine 5 is connected with the inlet of said micronizer main frame 6, and the outlet of said micronizer main frame 6 is connected with the inlet of said powder collector 7; Said powder collector 7 is provided with the secondary product outlet; Said powder collector 7 is connected with said fly-ash separator 8, and said air compressor machine 9 is connected with said fly-ash separator 8, and said fly-ash separator 8 is connected with said blower fan 10.
In the production process; After useless fragment of brick in the building waste and concrete blocks are broken into the small-particle below the 5mm through sand washer 1, crusher 2; Dry, send into feed bin 4 by lift 3 then, through feeding machine 5 material is evenly delivered in the bulk cargo dish on the rotating disk of little abrasive dust main frame 6; When little abrasive dust main frame 6 was worked, tens grinding rollers were in circuit internal rotation, rolling.Material looses to periphery under the action of the centrifugal and falls into mill chamber, in circuit by the grinding roller punching press, roll rollings, grind along with the inner air of high pressure positive blower 10 continuous pumping equipments, the material after the pulverizing of process multilayer is with the air of continuous entering; Be brought into the powder separating machine in little abrasive dust main frame 6; Tell the impeller of rotation that it is screened, underproof material falls after rise to be refaced, and qualified material gets into whirlwind powder collector 7 with air-flow; Dust falls, and is discharged by the discharge valve of its bottom and is finished product.The small portion fine dust gets into fly-ash separator 8 with air-flow, sticks to the filter bag surface.The high voltage pulse air-flow that air compressor machine produces is from the inner moment injection of filter bag, and the dust that adheres on it then falls because of the unexpected shake of filter bag, and the material that the transfer roller of bottom is then collected two places is seen off and carried out finished product packing.Uncontaminated air is after filtering finally discharged in the pure qi (oxygen) outlet, and the pure qi (oxygen) outlet is provided with sourdine.
Preferably, the production system of said construction refuse regenerated adulterant also comprises isolator 11, is installed in the outside of micronizer main frame 6.
Preferably; The production system of said construction refuse regenerated adulterant also comprises control computer, and it is connected with sand washer 1, crusher 2, lift 3, feed bin 4, feeding machine 5, micronizer main frame 6, powder collector 7, fly-ash separator 8, air compressor machine 9, blower fan 10, isolator 11 through Ethernet.
Use the production system of this construction refuse regenerated adulterant can produce a kind of construction refuse regenerated adulterant; This construction refuse regenerated adulterant can directly add according to a certain percentage makes mixed earth in the cement; Because the building waste later stage is corroded; Active substance quicklime wherein loses activity basically; Changed into calcium hydroxide and other compounds, wanted to utilize again the adulterant of these building wastes, must replenish an amount of quicklime to discarded concrete as new concrete; Active substance is wherein activated and replenishes insufficient active substance; Adopt alum, caustic soda, unslaked lime and aluminum oxide to do the compound activator of construction refuse regenerated adulterant, wherein alum, caustic soda are the active material quicklime that loses in the discarded concrete in order to activate, and unslaked lime and aluminum oxide are in order to increase the content of contained active substance quicklime in the discarded concrete.
Steel mill's grain slag that this construction refuse regenerated adulterant is can admixture an amount of and an amount of flyash are together as concrete admixture.
Test as follows for verifying construction refuse regenerated adulterant result of use:
The design orthogonal design table is following:
Orthogonal test table (annotate: % represents content, A-unslaked lime, B-alum, C-caustic soda, D-aluminum oxide)
Experimentation is following:
1, the building waste below the 5mm that pulverizes is put into micronizer main frame 6 and grind two kinds of 10min and 30min;
2, replace cement with 0,15%, 30% building waste respectively;
3, utilize a certain amount of alum, caustic soda, unslaked lime, aluminum oxide to do compound activator;
4, survey every group 7d, the folding strength of 28d, ultimate compression strength respectively.
Experimental result is following:
The anti-folding of cement paste 7d, 28d, the ultimate compression strength (grinding 10min) that contain 15% building waste
The anti-folding of cement paste 7d, 28d, the ultimate compression strength (grinding 30min) that contain 15% building waste
The anti-folding of cement paste 7d, 28d, the ultimate compression strength (grinding 10min) that contain 30% building waste
The anti-folding of cement paste 7d, 28d, the ultimate compression strength (grinding 30min) that contain 30% building waste
Experimental analysis: contain 15% and 30% grind the building waste adulterant of 10min 7d, 28d ultimate compression strength in, unslaked lime is bigger to the extreme difference of cement paste ultimate compression strength, the factor that just has the greatest impact.Can find out that through ultimate compression strength it is the highest to contain the intensity that 3% unslaked lime, 2% alum, 2% caustic soda, the proportioning of 2% aluminum oxide reaches, so can select this proportioning to use the effect of compound activator best.
Contain 15% and 30% grind the building waste adulterant of 30min 7d, 28d ultimate compression strength in, caustic soda is maximum to the extreme difference of cement paste ultimate compression strength, factor just has the greatest impact.Can find out that through ultimate compression strength to contain the intensity that 3% unslaked lime, 2% alum, 2% caustic soda, the proportioning of 2% aluminum oxide reaches the highest, so can select this proportioning to use the compound activator effect best.
Utilize building waste to do in the concrete admixture research; Because the active substance of building waste has lost activity; We adopt the mode that adds compound activator to activate the active substance in the building waste; This makes under certain proportioning situation, and intensity can reach requirement, so can come rationally to utilize building waste as the regeneration adulterant with the compound activator that adds an amount of proportioning.Draw in test with the building waste of content 15%, milling time 10min as the regeneration adulterant; And 3% quicklime, 2% alum, 2% caustic soda, 2% aluminum oxide have been used; Make that clean slurry intensity of test block is maximum, so in actual production, can this conclusion directly be used.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
