Since the Industrial Revolution, today's industries have been developed almost entirely based on petroleum energy, and today's standard of living has improved to a level not comparable to that before the Industrial Revolution, but the environmental pollution accompanying the development of the industry It is becoming a serious problem that threatens life.

Environmental pollution can be classified into air pollution, water pollution and soil pollution. Among them, soil pollution poses a serious threat to food production. In addition to causing serious pollution, it also causes pollution of groundwater So contaminated soils must be cleared quickly.

However, today's industry is based on the mechanical industry. Almost all machines require direct oil, such as lubricating oil and fuel. Especially oil which is consumed by various vehicles, which is one of the most essential in modern life Is consumed in such a large amount that it can not be quantified, and a considerable amount of oil is leaked to the outside due to carelessness and inevitable reasons in the transportation, storage and use of the oil, and the soil is polluted.

Also, in addition to the above-mentioned oil, various organic or inorganic compounds and heavy metals contained in the tailings discharged from the mine pollute the soil, and various methods for restoring the contaminated soil have been researched and developed.

Methods for recovering contaminated soil include physical and chemical methods such as soil washing, incineration, solidification, stabilization and solvent extraction, and biological methods such as soil cultivation, composting, bioventing, It is relatively easy to sort out the above methods and the soil is washed to recover the contaminated soil quickly because of the short treatment time.

Soil washing is a technique that uses a proper detergent to weaken the surface tension of harmful organic contaminants attached to soil particles or to separate them from soil particles by changing heavy metals into liquid phase, There is an advantage to be applied irrespective of the type of bar and pollutant.

The sorting drum 240 may include a sorting drum 240 for sorting and discharging the contaminated soil by particle size.

The conveying drum 210 is not shown in detail in the drawing, but may be installed to be rotatable on an upright stationary frame 270.

The transfer drum 210 has an inlet 211 formed at one side of the transfer drum 210 so that soil to be sorted can be introduced into the interior of the transfer drum 210 while an outlet 212 is formed at the other side to transfer the introduced soil toward the discharge port 212 And then discharged.

At this time, the inside of the transfer drum 210 can be divided into the first space 220 and the second space 230 by the virtual partition area A, The soil is transported and the crushing process is performed. In the second space 230, the soil transferred from the first space 220 is refined.

As shown in FIG. 7, the conveying drum 210 includes a spiral-shaped crush blade 221 formed along the longitudinal direction on the inner circumferential surface of the first space 220, so that the solidified It is possible to transfer the soil toward the discharge port 212 by the spiral structure while crushing the soil adhering to the soil or the stone having a large particle diameter.

The sorting drum 240 is coupled to the other side of the conveying drum 210 and rotates together with the conveying drum 210 when the conveying drum 210 rotates. The selection drum 240 has openings 241 and 242 formed at one side and the other side thereof to allow the soil discharged from the discharge port 212 of the delivery drum 210 to flow through the one opening 241, And a mesh net 243 having a predetermined gap. The soil having a particle diameter smaller than that of the air is separated and discharged, and the soil having a particle diameter larger than that of the air can be discharged through the other opening 242.

Here, the particle size of the pores can be selectively determined according to the purification condition of the contaminated soil, and preferably 10 to 50 mm so that the soil passing through the pores can be separated and discharged.

A plurality of horizontal bars 244 are formed on the inner circumferential surface of the sorting drum 240 at regular intervals so that the soil contained in the driving of the selection drum 240 is seated on the horizontal bar 244, So that the separation process of the soil can be performed more efficiently.

FIG. 9 is a side sectional view showing a stagnation plate according to an embodiment of the present invention, and FIGS. 10A to 10D are views for explaining the operation state of the drum shredding apparatus of the present invention.

Meanwhile, the drum shredding apparatus 200 according to an embodiment of the present invention can perform a soil refining process in the second space 230 of the transfer drum 210 as described above.

9, the transfer drum 210 further includes a stagnation plate 231 disposed at a boundary between the discharge port 212 and the discriminating drum 240 and having a communication hole 232 formed at a central portion thereof can do.

The stagnant plate 231 forms a step between the second space 230 and the sorting drum 240. Therefore, during the transportation of the soil until the stones flow into the second space 230 are accumulated, So that it is prevented from being introduced into the discriminating drum 240 at a time and is stagnated for a predetermined period of time.

This is because the stone or the like having a large particle size in the second space 230 is stagnated in the space of the second space 230 due to the rotational driving of the conveying drum 210. Therefore, It is transmitted to the discriminating drum 240 through the communication hole 232 beyond the stagnation plate 231. [

As a result, the stagnant stone or the like stuck in the second space 230 strikes the soil introduced into the second space 230 when the conveying drum 210 is driven to rotate. In the first space 220, The soil that has not been separated can be hit to crush the aggregated soil and to separate the soil adhering to the stone (gravel).

Hereinafter, an operation state of the drum shredding apparatus 200 according to an embodiment of the present invention will be described with reference to FIGS. 10A to 10D.

First, as shown in FIG. 10A, the feeding drum 210 receives the soil to be sorted through the inlet 211.

At this time, the soil to be selected may be a soil having a relatively large particle size in the collected soil, which has been previously sorted through a screen (not shown) such as a primary grizzly feeder.

The sorting target soil introduced through the inlet 211 of the conveying drum 210 may include a stone having a large particle size or a solidified soil and the spiral shaped crushing blade 221 formed on the inner peripheral surface of the first space 220 And then transferred to the second space 230.

Then, as shown in FIG. 10B, the soil transferred from the first space 220 flows into the second space 230 by the action of the shredding blade 221, and at this time, The stagnant plate 231 may be moved into the second space 230 so that the stagnant plate 231 can not be moved to the discriminating drum 240 at one time. 230).

As a result, the stagnant stone or the like strikes the soil accommodated in the second space 230 when the conveying drum 210 is rotated, as shown in FIG. 10C. By this action, in the first space 220, So that it is possible to easily perform the discharge of the soil by the particle size through the mesh net 243 in the subsequent process, i.e., the sorting process, through the subdivision process.

10D, the soil subjected to the subdivision process by the second space 230 may be introduced into the selection drum 240 through the second communication hole 232 of the stagnation plate 231. [

Since the outer surface of the sorting drum 240 is composed of the mesh net 243, the soil introduced into the sorting drum 240 can be separated and discharged according to particle diameters during the rotation driving process of the sorting drum 240, The soil having a smaller particle diameter than the pores of the mesh net 243 having the relatively large diameter can be discharged to the lower portion through the pores of the mesh net 243 and the relatively large- And is gradually discharged to the other side of the drum 240 through the opening 242 formed at the other side.

11 is a view showing an example in which the spraying nozzle 280 is further constructed in the drum shredding apparatus of the present invention. The spraying nozzle 280 continuously supplies water to the conveying drum 210 and the discriminating drum 240 So as to smoothly perform the crushing and sorting operations on the contaminated soil as the selected soil is transferred.

The injection nozzle 280 includes a first nozzle 281, a second nozzle 282, and a third nozzle 283.

As shown in the drawing, the first nozzle 281 is disposed in the form of a pipe along the longitudinal direction of the conveyance drum 210, and the high pressure water is sprinkled at predetermined intervals. And the soil that has accumulated in the soil can be crushed and the soil adhered to the stone can be separated.

The second nozzle 282 is disposed on the inner side of the sorting drum 240 so that the soil having a smaller particle diameter than the pores of the soil and the stone meshes 243 flowing into the selection drum 240 passes through the mesh net 243 Can be guided smoothly.

The third nozzle 283 is a means for washing the mesh net 243 and is arranged to spray water from the outside of the sorting drum 243 toward the mesh net 243.

The mesh net 243 is configured to allow soil having a smaller size than the gap to pass therethrough. However, in the case of soil and gravel having a particle size corresponding to the void of the mesh net 243, the mesh net 243 may be trapped in the mesh net 243, The mesh network 243 is blocked and can not perform its function properly.

Therefore, the third nozzle 283 is constructed such that the high pressure water is sprayed from the outside of the mesh mesh 243, thereby restoring the mesh mesh 243 that has been clogged by leaving the gravel and soil sandwiched by the mesh mesh 243 It will be possible.

At this time, the third nozzle 283 may be configured to operate continuously or intermittently.

It is preferable that the injection nozzle 280 is disposed on the upper side of the center of the conveyance drum 210 and the sorting drum 240. This is because it is possible to prevent the soil from being removed from the conveyance drum 210 and the sorting drum 240, Gravel (stone) and the like are passed between the center of each of the drums 210 and 240 by the gravity due to gravity, so that interference between the drums 210 and 240 can be prevented.

As described above, the drum shredding apparatus 200 according to the present invention may further include a drum shredding apparatus 200 for separating the soil or the solidified soil adhered to each other in advance in the transfer drum 210, Soil or the like can be easily separated, so that an accurate and efficient sorting process in the sorting drum 240 can be performed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.
