Structure and working principle, with reference to Fig. 1 and Fig. 2, overall technological scheme are as follows:
Step 1, vibration and sieving, this step carried out using vibrating screening machine, for example, vibrating screening machine can be selected it is mining,
Building waste special equipment obtains the concrete particle of ideal granule degree after shaking-sieving, and after sieving, granularity is straight
Diameter is generally Pyatyi: 0-5mm, 5-10mm, 10-20mm, 20-30mm, 30-40 and be no more than 40mm, for granularity be higher than 40
The material of millimeter needs crushing and screening again.Because the material size of the generation processing of different-grain diameter and surface area difference, are strengthening
In capillary cracking and additive also interfere with each other when immersing, so being divided into common five grades is conducive to strengthening effect,
One line of engineering is also helped, directly can provide material for roadbase and underlayment.
The substantially uniform consistent primary product of granularity are formed after preliminary screening, and the batch that the product point after classification is different
It is decomposed, there is more preferably effect.
Step 2, negative pressure are decomposed, by conveyer belt by sieve have crackle or complete concrete particle (such as
10-20mm grades) it is encased in negative pressure cabin 10, with reference to Fig. 2, that is to say, that in the concrete particle of this batch, have plenty of and have
Crackle, have plenty of completely, there is mixed speciality.Typically, for by complete particle also band particles having cracks
It is very difficult for directly sieve, and can carry out the two directly, quickly, accurately separating there is presently no technology
And screening.In negative pressure cabin, all into and out of behind channel after closing, the rolling first carried out ten minutes is stirred (by 20kw generator
Idler wheel is driven to provide power), revolving speed is 25 turns per minute.So that material to be fortified is evenly distributed in negative pressure cabin, is conducive in next step
Material surface cracking.The final vacuum degree of the negative pressure cabin is that (so-called vacuum degree refers to one no more than -101.325KPa
It is few under the density ratio standard state of gas molecula number in confined space), vacuum pumping pump carries out pumping and forms negative pressure shape in inside
State, after extracting internal air, at least pressure maintaining ten minutes during pressure maintaining, and combines the mode pair of far-infrared thermal radiation
Internal concrete particle is heated, and the process of heating is divided into two steps, and the first step is latter five minutes of pressure maintaining, persistently add
Heat, for the concrete particle internal temperature after heating in 100 degrees centigrades, 100 degrees Celsius described herein are only a generation
The exemplary temperature of table is lower than 80 degrees Celsius in general, such as 80 to 300 degrees Celsius of temperature space is all acceptable,
The good result further to crack cannot be then formed, if being higher than 150 degrees Celsius, energy consumption is higher in heating process, and synthesis is examined
Consider, select 100 degrees centigrades temperature be it is proper, second step be heating 35 seconds, suspend 15 seconds, continue five minutes,

During thermal expansion, slight crack can be made further to extend or Local Cracking, avalanche.
Step 3 wraps up in slurry, that is, uniformly wraps up one layer of mortar on the surface of concrete particle, firstly, opening negative pressure
The hatch door in storehouse, which is located at roller lower right, special using 18mm-25mm steel plate, and on-off mode is to open manually.At this
The process for opening negative pressure cabin hatch door should be moment, that is to say, that The faster the better for opening procedure, in open moment, and negative pressure cabin
Interior air pressure balance is by flash disruption, and cracking can occur in the case where air pressure cataclysm for the concrete particle with crackle, part collapses
It bursts, smaller particle is formed, and continuously rapidly drain into the concrete particle in negative pressure cabin in agitator, in the mistake of discharge
Cheng Zhong can further realize the explosion of defective concrete particle, can be picked by this step with the reduction of temperature
Except band particles having cracks, that is to say, that in this step, defective particle can crack to form smaller particle, this process is
Non-mechanical, and processing is fairly perfect, meanwhile, completely, do not have particles having cracks to be substantially unaffected, stills remain in
Good working condition originally.Meanwhile slurry (water and C25, C30 cement for wrapping up concrete particle are injected in agitator
The cement slurry of proportion), the proportion of the slurry are as follows: (water: cement=1:1 or 1:0.8, mass ratio) utilizes negative pressure cabin, agitator
