The present invention relates to an ultrasonic oscillation apparatus for recycled aggregates applied to a recycled aggregate production process obtained through a construction waste treatment process such as waste concrete, waste asphalt concrete, waste mortar, and more particularly, among recycled aggregates that have undergone washing and sorting. Selecting sand with high specific gravity and foreign matter with relatively low specific gravity, but mixing ultrasonic particles with physically separated foreign matter and sand that is mixed with recycled aggregate before going through various stages of cyclone using vortex phenomena and specific gravity. The present invention relates to an ultrasonic oscillator for recycled aggregate which can be separated and sorted more reliably by pulverizing and sterilizing washing by oscillating at the bottom.

In general, in the construction waste treatment process, coarse aggregates (gravel) and fine aggregates (sand) are screened from recycled aggregates, and as shown in FIG. 1, foreign matter and light sand sorting methods of construction wastes are selected to sort construction wastes into recycled aggregates. In the process, the sand mixture is introduced into the washing unit 311 above the washing selection body 310 so that the washing and sorting again, and the injected sand mixture is washed by the water sprayed from the water spray port 331 under the feeding unit 311. Aggregate sand having a greater specific gravity than water is moved along the conveyor belt 321 and the remnant soil and light weight waste having a specific gravity smaller than the water are moved in accordance with the flow of the injected water, and the separation plate 333 at the other end of the conveyor belt 321. The washing sorting step made by the washing sorting apparatus 100, the remaining soil and light wastes are sorted according to the specific gravity, and the washed and sorted aggregate sand is divided by the rotor mill 361. After the process, the sand screen 362 is selected by the aggregate (363) and sand (367), the sorted sand (367) is again classified by the sand unit 365, the sand (367) is sorted and lightweight sand Aggregate and sand sorting step to be moved to the sedimentation tank (366), and the washed and sorted lightweight waste through the dehydration screening process by the dewatering screen 351, the final lightweight waste (343) is screened and the remaining sand sand unit (365) Lightweight waste sorting step to be moved to the washing, and the sorted light-weight sand through the screening process using the vortex of the cyclone 370, the light sand with a high specific gravity through the dehydration screening process by the dewatering screen 352, the final light sand The sand mixture, which is screened at 355 and has a low specific gravity, comprises a light sand sorting step that is moved to the sand unit 365.

On the other hand, with the action of the screw filter for recycled aggregates look at the foreign matter and light sand sorting process of construction waste as shown in Figure 4 as follows.

The sand mixture selected in the process of sorting the construction wastes into recycled aggregates is introduced into the input part 311 of the upper part of the washing sorting body 310 to be washed and sorted again, and is introduced into the water injection hole 331 under the input part 311. As the sand mixture is washed with water, aggregate sand 341 having a greater specific gravity than water is moved along the conveyor belt 21, and the foreign particulate sand 343 mixed with xantrite having a smaller specific gravity than water is moved according to the flow of sprayed water. do.

In addition, the separated foreign matter sand (343) is separated into the foreign matter, water and mixed sand by the screw filter 210, the separated mixed sand is moved to the cyclone 220 to be separated, the specific gravity smaller than separated water And water is moved to the settling tank 221 and the separated sand is moved to the dehydration screen (260).

In addition, the screw filter 210 is a device for compressing the bulky foreign matter foamed, such as styrofoam to separate from the sand mixed with water and sand.

And the washed and sorted aggregate sand 341 and the external gravel (sealing) 345 is moved to the sand screen 230 to be sorted by sand (5 mm or less) and aggregate (5 mm or more), and the selected sand (5 mm or less) Is moved to the ultrasonic oscillator 240 and the aggregate is selected as sand (5 mm or less) and residual aggregate (5 mm or more) by the sand screen 362 through the grinding process by the rotor mill 361, The aggregate is again subjected to the grinding process by the rotor mill and the selected sand is moved to the ultrasonic oscillator 240.

Here, the sand screen which is commonly applied in the process of screening sand is used, and the detailed configuration of the rotor mill is sufficient if it is generally applied, and thus detailed description thereof will be omitted.

And the sand mixed with the foreign matter moved to the ultrasonic oscillator is sterilized and crushed by the ultrasonic oscillator is moved to the first, second, third cyclones (101, 102, 103) of the three stages to undergo a separation process.

Here, the ultrasonic oscillator 240 is an ultrasonic oscillator that generates bubbles, the sand mixed with foreign matter along the chute 40 is present in the sand while moving the upper oscillation unit housing 10 and the middle oscillation unit housing 10 upper portion of the two sides. By generating bubbles in the foreign matter, the recycled aggregate is crushed and sterilized and washed.

In addition, the oscillating part housings 10 on both sides are ultrasonic generators that generate 20 KHz of oscillation and are directly excited with ultrasonic waves at the bottom of the mixed sand moving with water. If the excitation of 20 KHz presented in the present invention, it is possible to grind the cracks of the recycled aggregates, so that the cracked recycled aggregates are washed again by continuously moving water.

And the middle oscillating part housing 10 is about 40 KHz through the excitation to not only mixed sand but also to sterilize the foreign matter contained with the water, in particular the oscillating part housing 10 located in the middle of the oscillating part housing ( It is formed at a lower position than 10), so that sand and xanthus, which have a relatively low specific gravity, are gathered at this low position, so that the sterilization and washing action of sand and xanthone having a relatively low specific gravity can be more surely performed.

In addition, the frequency control switch can be adjusted to adjust the frequency. Pressing the sweep button generates aeration in the 50Hz-1KHz band to clean the aggregate, and separate the crushed foreign matter from the sand to float upwards. And it also removes bubbles generated during the cleaning process.

And the sand mixed with the foreign matter passed through the ultrasonic oscillator is introduced into the inlet 111 of the first cyclone 101 as shown in Figure 5 rotates in a spiral due to the vortex phenomenon, the sand and water having a large specific gravity lower outlet 121 ) Is discharged to the foreign matter discharge port 132 through the upper side of the separation plate 134 and is introduced into the dehydration screen 211.

In addition, although the specific gravity is relatively small, the unseparated foreign matter and sand are discharged through the unseparated discharge outlet 133 and then injected into the inlet 111 of the second cyclone 102.

In addition, the foreign matter and sand introduced into the second cyclone is rotated in a spiral like the first cyclone by vortex phenomena, and the large specific gravity sand and water are discharged to the lower outlet 121, and the foreign matter having a relatively small specific gravity is separated from the separator 134. ) Is discharged through the upper side of the foreign matter discharge port 132, the specific gravity is relatively small, but the unseparated foreign matter and sand is discharged through the non-separated water discharge port 133 to the inlet 111 of the third cyclone 103 Is committed. Like the first cyclone, foreign substances discharged from the upper side of the separator are directly introduced into the dehydration screen 211.

In addition, the introduced foreign matter and sand are rotated helically by the vortex phenomena, and the sand and water having a large specific gravity are discharged to the lower outlet 121, and the foreign matter having a relatively small specific gravity is discharged to the side outlet 131.

In addition, in the third cyclone 103, the xantho soil having a smaller specific gravity than the water mixed with the foreign matter and water is moved to the dehydration screen 211 through the side discharge port 131, so that the foreign matter is separated separately, and the xantholite having a specific gravity smaller than the water mixed with the water is separated. Is moved to the settling tank 221.

Sand and water are moved to the dehydration screen 260 through the lower outlet 121 of the second and third cyclones 102 and 103, so that the light sand having a specific gravity of 1 or less is separated and the sand and water having a specific gravity of 1 are sand. The dehydration screen 250 is moved.

Here, the dewatering screen 260 is composed of an aggregate transfer screen (not shown) having a vibrating reverse slope, and finally, the dehydrated lightweight sand is discharged from the aggregate transfer screen. The aggregate transfer screen uses a 0.3 mm urethane net.

In addition, the light weight sand separated separately has a specific gravity of 1 or less, the specific gravity is low, and the light absorption rate is 4% or more, the water absorption rate is high and the curing action does not occur, so the sand is not suitable for use as ordinary sand, the light sand referred to in the present invention is Quoted with the same definition.

In addition, sand and water are moved to the sand dehydration screen 250 through the lower outlet 121 of the first cyclone 101, and the reclaimed sand is separated separately and the remaining clay having a smaller specific gravity than the water mixed with the remaining sand and water is another cyclone ( After moving to 370, the sand is moved back to the sand dewatering screen, and the residual soil having a smaller specific gravity than water mixed with water is moved to the settling tank 221.

The cyclone 370 is shown in FIG. 4. In other words, the sand and the residual soil mixed with water are introduced into the inlet 371 of the cyclone, it is preferable that the inlet 371 is configured in a spiral so as to form a vortex. While forming a vortex, the water and fine sand having a smaller specific gravity flow into the upper outlet 372 to be moved to a thickener, a sedimentation tank 221, through the process of solidification of sludge and discharge of waste water, and the specific gravity is relatively As a result, the large lightweight sand is discharged downward to the lower discharge port 373. Since the cyclone falls from the top, it is possible to operate without a force.

The reclaimed sand separated in the reclaimed sand separation step is separated into a state suitable for use as general sand with an absorption rate exceeding 4%.
