Next, if necessary, a second separation mechanism 40 for separating the discharged water with the recycled aggregate and sand adjacent to the discharge mechanism 3 of the recycled aggregate from which impurities are removed from the waste concrete is provided. In the case of 40, the perforated plate, net or various round rods are formed in the form of a beak member 44 which is installed to have a predetermined gap in front of the support 42, and the recycled aggregate is a hole in the perforated plate or net of the separating member 44. Alternatively, the gap and the discharged water passing through the separation member 44 are prevented from passing through the gap so that the sand and the discharged water may be rapidly connected to the second immersion tank 50-2 of the immersion tank 50. Do. At this time, the feed pipe line 48 is connected via the hopper 46 located in the lower portion of the separating member 44 in order to prevent the sand and water to be moved to the second settling tank (50-2) blocked during feeding. ) Is preferably formed to have a U-shaped cross-sectional shape.

In addition, if necessary, the first and second immersion tanks 50-1 and 50-2, which are part of the immersion tank 50, may be manufactured in a cylindrical shape, and the first and second immersion tanks 50-1 and 50-2 may be formed. At the bottom of the center, an opening recess 52 is formed, and on one side of the immersion tank 50, a guide frame 56 having a discharge port 54 is formed at the top in the same direction as the opening recess 52, and the immersion tank ( Inside the 50, a sediment discharge mechanism 60 for discharging the sediment and a sediment collection mechanism 70 for collecting the sediment to one side are provided, in the case of the sediment discharge mechanism 60, the first and second As the inner side of the needle tank (50-1, 50-2) is installed adjacent to the inner side of the opening recess 52 and the guide frame 56, the scraper 62 is installed at regular intervals, and is usually driven by a drive motor It is configured in the form of a conveyor, the sediment collection mechanism 70 is the rotary shaft 72 mounted on the upper portion of the first and second settling tank (50-1, 50-2) The lower portion of the scraper 74 is installed to operate in contact with the bottom of the first and the second needle tank (50-1, 50-2) and the rotating shaft 72 is installed in the drive motor 76 It is configured to be made to rotate slowly by.

It is possible to control the operation of.

The vibratory chute 20, the first and second separation mechanisms 30 and 40, the sediment discharge mechanism 60, the sediment collection mechanism 70, and the heating mechanism 80 described above may be simultaneously installed or otherwise necessary. It is possible to apply and install selectively in the city.

Reference numeral 22, 24, 26 denotes a pump, 28 denotes a sediment discharge mechanism of the sump tank 1, 50-3 denotes a sediment discharge mechanism 60 or a sediment collecting mechanism 70 is not installed 3 Indicates a tide tank.

In the case of the treatment device of the present invention made as described above can be made as follows.

First, water is supplied to the water tank 1 using a feeding line 9 up to a predetermined level to prepare water for treatment, and the water pocket 10 is pumped by pumps 14 and 14 and feeding lines 16 and 16. The vibratory chute 20 is supplied by the feeding conveyor 8 to the crushed waste concrete in the state where the high pressure water is supplied and the injection of the high pressure water through the nozzle 12 is directed toward the water surface and the vibrating chute 20 is operated. When falling to the top of the) is dispersed in accordance with the specific gravity of the waste concrete falling by the vibrating action of the vibrating chute 20 is dropped into the input mechanism (5). At this time, since the high-pressure water is injected through the nozzle 12 from both sides of the water pocket 10 of the inlet mechanism 5 to fall into the water in the inside of the water collecting tank 1, it is dropped in the dispersed state by the vibrating chute 20 The waste concrete and other impurities are subjected to surface washing and separation of suspended impurities early by the high pressure water.

Thus, the impurities that float to the upper surface of the water is discharged to the outside by the suspended air discharge mechanism (7) that was operating in the air, the water coming out along with the impurities through the separation plate 34 of the first separation mechanism (30) Falling into the furnace, only the pure floating impurity which flows to the first settling tank 50-1 and has some water removed is discharged to the outside.

In addition, the pure waste concrete in which suspended impurities are separated and removed and falls to the bottom of the water is placed on the upper part of the discharge mechanism 3, such as a conveyor at the lower part, which has been in standby operation beforehand. In this case, in the case of the waste concrete from which the washing and the impurities are removed, the recycled aggregate and the sand below the predetermined size are kept mixed, so that the separating member of the second separation mechanism 40 is discharged to the outside. (44) to pass through it and the sand and water falling to move to the second settling tank (50-2) to obtain a pure recycled aggregate discharged without passing through it.

The sand, soil, and water moved to the first and second sedimentation tanks 50-1, 50-2 and the first, second and third sedimentation tanks 50-1, 50-2, 50-3 and As a result of the multi-stage removal of sand or soil, it is preferable to re-supply it to the water collecting tank 1 for the treatment of waste concrete in a state where it is purified to some extent, whereby recycling is performed. Sand or soil that sinks to the bottom of the 50-1, 50-2 is discharged to the outside by the sediment collection mechanism 70 and the sediment discharge mechanism (60). That is, the sediment and the second sedimentation tank (50-2) and the like sediment accumulated in the first sedimentation tank (50-1) by the scraper 74 attached to the lower portion of the rotary shaft 72 of the sediment collection mechanism 70 Sediment, such as pure sand accumulated at the bottom of the scrape scrapes the bottom of each of the first and second sedimentation tank (50-1, 50-2) and sweeps the inside of the opening recess (52), the opening recess 52 The sediment collected into the inside of the) is gradually discharged to the outside according to the conveyor operation by the scraper 62 of the sediment discharge mechanism 60, and eventually the first and second sedimentation tanks 50-1 and 50-2. The sediment precipitated therein is discharged to the outside step by step and the internal purification of the first, second and third sedimentation tanks 50-1, 50-2, 50-3 forming the sedimentation tank 50 is sequentially performed. .

In particular, the sand discharged to the outside by the sediment discharge mechanism 60 from the second settling tank (50-2) is already washed, so it is possible to collect it and recycle it to fine aggregate.

In addition, when the temperature of the outside air drops, such as in winter, the water inside the sump tank 1, the water pocket 10, and other pipe feeding lines 9, 16, 18 is frozen, and the damage is expected. By operating the 80 to prevent the water passing through the components (1, 10, 9, 16, 18), etc., it is possible to prevent damage in advance.

As described above, according to the treatment device of the present invention, the water chute 10 having the spray nozzle 12 is installed on the rear surface of the feeding mechanism 5 installed adjacent to the water collecting tank 1, 20, or the sediment discharge mechanism 60 and the sediment collection mechanism 70 of the first and second separation mechanisms 30 and 40, and the first and second sedimentation tanks 50-1 and 50-2. In addition, the heating mechanism 80 may be installed as a whole or selectively, and the process of re-utilizing the impurities, aggregates and sands from the removal of impurities, and reprocessing the discharged water may be carried out in whole and continuously. Improve the efficiency of the work by improving the removal process periodically and preventing the freezing of water existing inside the sump (1) or other components even in winter, and when work is stopped at night or temporarily Even if To resume has excellent effects such as to prevent damage due to freezing.
