s5, respectively conveying the stones with different diameters into different stirring machines, and stirring the stones by the stirring machines;
and S6, adopting a vibrating screen to carry out vibrating screen on the stone stirred by the stirrer, screening out the stone with small hardness after the diameter is reduced by the vibrating screen, and keeping the stone with large hardness in the vibrating screen.
As a further improvement of the invention, the method also comprises a step S7 of washing the screened stone material with water.
As a further improvement of the present invention, in step S1, the construction waste is transported to the sludge-residue treating apparatus, and water is introduced into the sludge-residue treating apparatus, the sludge-residue treating apparatus separates the first stone blocks having a volume larger than a set value from the construction waste, and the second stone blocks having a volume smaller than the set value are discharged to the storage tank together with the muddy sand and the water.
As a further development of the invention, in step S2 the first stone block is conveyed to a jaw crusher, which crushes the first stone block to a third stone block of a set size according to the actual production demand, which third stone block is discharged from the jaw crusher and falls onto a conveyor.
As a further development of the invention, in step S3, the sieving machine at the holding tank separates the second stone block from the silt and pushes the second stone block onto the conveyor.
As a further improvement of the invention, in step S4, the third stone block discharged from the jaw crusher and the second stone block discharged from the storage tank are conveyed by a conveyor to a vibrating screening device, which screens the stone material into stone materials of different diameter sizes.
The invention has the beneficial effects that: through the scheme, the building waste soil is classified into the aggregate with low hardness and the aggregate with high hardness through vibration, crushing and screening, so that the building waste soil with the same hardness is screened, and the value maximization of the building waste is favorably realized.
Detailed Description
The present invention will be further described with reference to the following embodiments.
A method for processing stones in building spoil specifically comprises the following steps:
s1, transporting building waste soil to a sludge and residue treatment device, and introducing water into the sludge and residue treatment device, wherein the sludge and residue treatment device separates large-volume stones from the building waste soil, and the small-volume stones, silt and water are discharged into a storage tank together;
s2, conveying the large stone blocks into a jaw crusher, crushing the large stone blocks into small stone blocks with preset sizes by the jaw crusher according to actual production requirements, and discharging the small stone blocks from the jaw crusher and then falling onto a conveyor;
s3, separating the stone material from the silt by using a screening machine at the storage tank, and pushing the stone material to a conveyer;
s4, conveying the stones discharged from the jaw crusher and the stones discharged from the storage tank to a vibrating screening device by a conveyor, and screening the stones into stones with different diameters and specifications by the vibrating screening device;
s5, respectively conveying the stones with different specifications to different mixers, wherein when the mixers are operated, a stirring rod of the mixer continuously beats the stones, and the stones also continuously impact the body wall of the mixer, the specific stirring time and the stirring speed are set by an operator according to the types of the stones, the stones with lower hardness are crushed due to the impact of the stirring rod and the body wall, so that the diameter of the stones with higher hardness is reduced, and the diameter of the stones with higher hardness cannot be changed too much;
s6, vibrating and screening the stone materials stirred by the stirrer by using a vibrating screening machine, wherein the vibrating screening machine can screen out the stone materials with smaller diameters and smaller hardness, and the stone materials with larger hardness are left in the vibrating screening machine due to small diameter change;
and S7, washing the various screened stones with water to remove excessive powder on the surfaces of the stones, thus finishing the treatment of the various stones.
The building waste soil contains a large amount of mud sand stones, wherein the stone stones have a plurality of stones with different hardness, and the stone stones in the building waste soil are classified into the aggregates with small hardness and the aggregates with large hardness through vibration, crushing and screening, so that the stone stones with the same hardness are screened, the proportion of the stone stones in the building waste soil is large, and the recycling of the stone stones is an important link for the building waste soil treatment; the stones contained in the stones are various in variety, and the sieving ratio of stones with different hardness is indispensable for reasonably utilizing stones with different hardness; meanwhile, in commercial operation, the value of stones with different hardness is different, and the invention can better realize the maximization of the value of stones.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
