Description

Lightweight garbage disposal apparatus of construction wastes {The constructive equipment of reclaimed waste}

The present invention efficiently sorts and sorts out various types of solid waste such as waste concrete, waste wood, and waste plastic paper, iron pieces, and glass, which are a kind of construction waste, removes fine powder, and forms urban-based materials such as concrete aggregates. The present invention relates to a method for recycling construction waste, and a device (selection application No. 2000-23608, filed date of application date 2000.05.02.) Characterized in that it can be recycled.

In other words, this paper is a kind of dry specific gravity sorter, which is used to remove lightweight solid wastes such as cloth and glass pieces, as well as lightweight aggregates with durability problems. It can be separated and sorted, and it is a device that sorts and sorts by a kind of vacuum flotation method which has the advantage that it is excellent in the unit weight increase and decrease of aggregate.

Conventional methods for sorting lightweight garbage include collecting lightweight waste from the tank and placing a small amount of waste on the tank after passing a conveyor carrying crushed materials including waste into the water of a tank equipped with a wooden tank. It was transferred to the ship. Therefore, this has the advantage that dust is not scattered, but as the conveying conveyor passes through the water, there is a high possibility of mechanical corrosion due to the sludge treatment of discharged water after passing. There was a problem such as a high installation cost because there must be a separate device to be dried even if collected in the collection box by aeration tank.

The present invention is made dry in view of the above-mentioned conventional problems, and the front end direction of the fixed drum is about 30 ° from the center of the upper surface of the fixed drum, so that it is relatively light waste plastic, waste plastic paper, waste cloth, etc. The vacuum flotation and the specific gravity of 1 ~ 1.8 light aggregate is separated by the discharge conveyor over the fixed drum, so that it can be sorted in a single operation at a time, which is described in detail according to the accompanying drawings as follows.

Figure 1 is a schematic cross-sectional view showing the overall configuration of the present invention.

Figure 1 of the accompanying drawings is a schematic cross-sectional view showing the overall configuration of the present invention, Figure 2 is an enlarged cross-sectional view of the 'A' portion of Figure 1 upper center of the fixed drum (2) fixed to the inner wall (O) (O) A) (30) point (A) in front of the wind generator (3) to match the direction point (B) (C) of the wind guide tube (4) and move the debris including waste directly above the wind generator (3) The conveyor 5 is provided.

Directly below the fixed drum (2), the discharge conveyor (6) is installed at a slight interval to discharge the light garbage and lightweight frame that has passed over the fixed drum (2), and the aggregate having a weight of 4 or more is discharged from the fixed drum (2). Rolling is carried out to the conveyance conveyor 7 by rolling at the space | interval D of the conveyor 6. At this time, the wind power of the wind generator 3 is about 24000m³ / h. In the drawings, reference numeral 8 denotes a garbage and light frame collector, 9 a support frame of the body 1, and 10 a chute of the conveying conveyor 7.

The present invention constituted as described above mainly relates to a device for sorting lightweight waste and light aggregate in the process of crushing, sorting, washing and separating to recycle construction waste. 40 ~ After crushing about 80 degrees, the rebar is separated and put in the washing process. That is, the crushed matter including the light garbage put into the hopper installed at the rear end of the mobile conveyor 5 of the main body 1 moves in the mobile conveyor 5 and falls directly above the wind generator 3, wherein the wind generator ( The position of the direction point (B) (C) of the tip wind guide tube (4) of 3) coincides with -30 ° point A in front of the center (A) of the fixed drum (2) fixed to the body (1). Lightweight garbage such as waste plastic, waste plastic paper, waste cloth, waste wood, etc., which are weaker than the generated winds, are blown to the ceiling side of the aircraft (1). Along with the fixed drum (2) to fall to the upwardly inclined discharge conveyor (6) will be collected in the collection box (8) through the tip outlet of the gas (1) together with the lightweight waste.

In addition, heavy aggregates having a specific gravity greater than 2.2 due to the strong wind power of the wind generator 3 can not be discharged by the inclined discharge conveyor 6 and rolled backward to the chute 10 of the transfer conveyor 7. Dropped to the side) is transferred to the next process with the fractured bones that win the wind. Of course, by adjusting the number of revolutions of the wind generator (3) can be adjusted according to the sorting the wind to sort the main can double the screening efficiency.

As described above, the present invention is a process for recycling construction waste materials, and the lightest waste such as waste plastic, waste plastic paper, waste cloth, waste wood, etc., which were the most problematic among the processes, is selected by vacuum flotation and unit weight of aggregate. The lightweight aggregate that has a great influence on the wind generator (3) can be sorted by use according to the wind control of the wind generator (3). The scattering of dust is more than the underwater buoyancy selection method, but it can be prevented to some extent by spraying water around and the efficiency is underwater. Compared to the buoyancy screening method, it has a superior effect and has various effects to maximize the screening efficiency.
