In the polishing separation apparatus according to the present invention configured as described above, the hose or chute is installed at the outlet of the screw pump 152 to guide the fine sand tank (not shown), and the upper plate 112 at the top of the separation tank 110. The hole formed in) is installed so that a certain amount of aggregates from which waste concrete is crushed can be continuously added with water. At this time, when the water is filled up to the upper portion of the separation tank 110, the lower end of the separation tank 110 and the box-shaped passage 240 of the conveyor 200 are integrally installed and thus the box-type cylinder of the conveyor 200. The furnace 240 is also filled with water as much as the height of the fluid of the separation tank (110). The reason for operating after filling with water in this way is to create the condition of the state which is still in operation, and to prevent the machinery from being overwhelmed.

In this state, power is applied to the first and second motors 114 and 140 to be driven, and the conveyor 200 including the vibration motor 253 is also driven. When the first motor 114 is driven, the rotary shaft 116 connected to the first motor 114 is rotated, the rising vortex fan 118 of the rotary shaft 116 also rotates together, the separation tank 110 The internal water (wash separation water) is vortexed by the rising vortex fan 118.

At the same time, when the second motor 140 is driven, the drive shaft 144 is interlocked through the reduction gear 142 and the ring gear 130 on the top of the rotating drum 120 meshed with the drive gear 144. Is rotated, and the rotating drum 120 integrated with the ring gear 130 is rotated at a high speed. At this time, the rotating drum 120 should be rotated in the opposite direction to the rotating shaft 116. The reason is that the aggregate moved radially by the centrifugal force of the rising vortex collides more firmly with the striking rod 122 on the inner surface of the rotating drum 120 and rolls along the protrusion 124 to be polished.

Gravel, sand, etc., obtained by crushing the waste concrete in this state is supplied from the upper portion of the separation tank 110 with water and rotates inside the separation tank 110 through the hole of the upper plate 112 on the top of the separation tank 110. Injected into the drum 120, the fine sand or suspended matter in the gravel and sand introduced in this way is floating due to the rising vortex generated as the rising vortex fan 118 of the rotary shaft 116 is rotated.

As such, the fine sand and the floats do not sink due to the rising vortex and remain in the floating state, and are collected into the collecting device 150 above the rotating drum 120, and the collected floats or particulates are driven by the screw pump 152. As it is sucked into the product and discharged, it is discharged to the fine sand tank through the hose.

The fine sand introduced into the fine sand tank is a rapid laminar flow of water in the fine sand tank and is simply flowing laminar and settles to its bottom, which can then be used as a mass using a screw conveyor.

On the contrary, while the fine sand and the coarse sand are overcome by the rising vortex and are dropped by their own weight and are radially dispersed toward the inner surface of the rotating drum 120 by the centrifugal force of the rising vortex, the striking rod 122 of the inner surface of the rotating drum 120 It is hit several times in succession, thereby separating the foreign matter (floating material, etc.) or paste on the gravel surface between the sharp edges of the crushed gravel surface, as well as bluntly sharpening the sharp edges.

Simultaneously repeating the falling process while rolling along the triangular protrusion 124 formed on the inner surface of the rotating drum 120, the edges of the sharp particles become rounded and blunted.

As described above, the striking rods 122 and the protrusions 124 of the inner surface of the rotating drum 120 rotated at high speed continuously strike the gravel and the coarse sand falling into the water along the inner surface thereof, as well as rolling continuously. This is possible and thereby better quality aggregates can be obtained.

As described above, the residues of coarse sand and coarse sand are dropped through the lower portion of the rotating drum 120 to fall on the belt 230 of the conveyor 200. Thus, the coarse sand and coarse sand dropped on the belt 230 are belts 230. Driven by the roller 220 of the conveyor frame 210 is transported to the top of the bucket conveyor 200 by the bucket of the belt 230 and then discharged. At this time, the bucket on the belt 230 is a plate-shaped plate 231 and el-shaped plate 232 having a plurality of holes perforated, so that when the water rises higher than the surface of the separation tank 110, only water and coarse sand and coarse sand remain. When passing through the upper roller 220, the residue and coarse sand falls and is collected.

As such, when the fine sand and coarse sand falls, vibration is also transmitted to the plate-shaped plate member 231 and the el-shaped plate member 232 of the belt 230 by the vibration motor 253 of the vibrator 250. It does not remain on the plate 232 and falls clean.

The residue and coarse sand discharged in this way can be utilized as it is or after being sorted by a sorting machine.

Figure 7 is a cross-sectional view showing another embodiment of the abrasive separation apparatus according to the present invention, the rising vortex fan 118 of the rotating shaft 116 is a shape of both ends higher than the center of the rotating shaft 116, that is, the overall shape is V-shaped Except as provided, the configuration is the same as the configuration of FIGS. 1 to 4 of the present invention. At this time, the striking rod 122 should also be careful not to interfere with the rotation of the rising vortex fan 118.

According to the configuration of another embodiment as described above, when the rising vortex fan 118 is rotated by the first motor 114, the water level increases as the fluid in the rotating drum 120 moves away from the center, thus rotating drum 120 ) Even though the water level of the inner surface portion is increased, since both ends of the rising vortex fan 118 are highly V-shaped, they can be efficiently stirred, so that the particles to be separated from the gravel and sand become uniform, and thus, fine fine sand can be obtained. will be.

The power of the second motor 140 is shown and described as a drive gear 144 and a ring gear 130 driven through the reduction gear 142 as a power transmission means for driving the rotary drum 12 in the apparatus of the present invention. However, it will be obvious that the pulleys may be mounted on the output shaft of the second motor 140 and the pulleys are also mounted on the upper end of the rotating drum 120 to connect the pulleys to each other with a belt.

As described in detail above, the abrasive separation device according to the present invention, the gravel and sand crushed waste concrete is hit by the striking rod of the inner surface of the rotating drum rotated at high speed by the rising vortex and rolled along the projection of the inner surface During the natural fall in the water while repeating the process, it is possible to separate the suspended matter stuck between the paste on the gravel surface or the sharp particles on the surface of the gravel, and dull the sharp particles to discharge to the bottom.

In another aspect, the present invention by providing a water collecting device having a screw pump in the upper center of the rotating drum is separated from the gravel by the rising vortex of the rising vortex fan to discharge the suspended matter and fine sand collected in the center, thereby It has the effect of obtaining high quality gravel and coarse sand falling to the bottom.

And the present invention is to install the conveyor integrally in the lower part of the separator, but the box-type passage in the conveyor from the bottom to the top so that the fluid in the separator does not leak, the separator and the conveyor can be installed on the ground rather than the water tank can be used Because of this, it is a useful invention that can minimize the construction cost and occupied space according to the construction of the tank.
