Abstract

The present invention relates to a convenient wet-type sorting machine for construction waste to strengthen the content of recycled aggregate foreign substances. Existing sorting machines need a lot of land and are having difficulty in treating sludge or fine stone dust in a sorting tank. The sorting machine of the present invention is 73.8 m^3 size and additional installation is easily performed. In order to prevent sludge generation, the recycled aggregate in which the soil is completely separated through a grazing feeder (vibration screen) is put into the sorting tank. The floating foreign substances are pushed to a stainless mesh conveyor and discharged, and recycled aggregates without foreign substances are put into a stone dust cone through a transfer conveyor which removes moisture to be produced into fine dust or aggregates of 25 mm or less. The fine stone dust settled in the sorting tank is transferred to a water tank A through a scrap bar and a circulation valve, and recycled with stone dust. In a situation that recycling costs are higher than landfill costs, recycling rates and quality can be increased and costs can be reduced.

Description

Construction Waste Simpieness Wet-Type Sorting machine

The present invention relates to a construction waste wet sorting device, which makes the existing device smaller and more efficient. It is designed to have all the functions of the wet separator in 18.3㎡. The biggest problem of the existing wet sorter was the biggest problem with the large tank and sludge treatment, but the present invention is to install the grazing feeder first to prevent the sludge generation by separating the soil first, and to remove the tailings inside the sorting tank with water. Transfer to a water tank to be used with stone powder, and relates to the segregation of construction waste foreign material to clean the sediment stone in the sorting tank by using the water of the supplemental circulation pump.

The accumulation of tailings in the sorting tank was carried out by transporting the natural sediment to the outside by installing scrap bars (6) of the vehicle wheel washing machine in the existing construction site under the sorting tank. The solution was completely solved by installing a circular lever (8) at its vertices to be transferred to tank A with water.

The foreign matter suspended in the sorting tank was solved by designing it to be transported and discharged to the stainless steel mesh conveyor (3).

Wet separators currently in use are struggling with sludge treatment in water. After a certain period of time, the sludge or tailings precipitated on the floor is stopped and pumped into a large sedimentation tank to solidify it with sedimentation chemicals. In addition, due to the sludge remaining in the sorting tank, the conveyor belt drive is not natural, and the amount of water moved with the aggregate is larger than expected, so it is carried over to the next belt.

In order to prevent sludge generation by installing the grazing feeder first in front of the jocchersha, the large amount of foreign matter was sorted by hand and wind before the sorting tank, and the crushed construction waste was put into the sorting tank. .

The water inside the sorting tank was sprayed to the stainless mesh net conveyor (3) using a 0.5 hp small submersible pump spray nozzle (5) to allow foreign substances to easily ride on the conveyor and to be drained easily without draining. 3) was used, but was too sensitive to the water level, there is a phenomenon that the water is transported together, there is a hassle that the water removal work must be performed in parallel was changed to a stainless mesh conveyor.

Selected good quality aggregate is transferred to the stone mill cone by the conveying conveyor (4), which makes the water drain hole on the belt and attaches the anti-slip jaw (Fig. 5) to smooth the water drain and prevents the flow of the aggregate during transportation. Prevented.

30% of the tailings powder was discharged using a scrap bar (FIG. 6), and the remaining 70% was precipitated by going to the water tank A with water through the circulation valve 8, and the water was pumped and reused into the sorting tank.

The pumped water was designed to make the water to be transferred to the tank A from the inside of the sorting tank by spraying water toward the top of the square pyramid by making a spraying facility (Fig. 6) on the top corner of the sorting tank and the top corner of the history pyramid.

The circulation lever 8 was installed so that the amount of pumped water and the amount of overflow 9 was well controlled, and the sorting tank was always circulated with the overflow 9 so as not to accumulate tailings. Overflow is connected to the recovery pipe (12: water recovery flow from the aggregate transport conveyor) and the level control is performed so that foreign matter is well filtered through the stainless mesh strainer conveyor, and the remaining foreign matter is further sorted through this passage. have.

The water tank (Fig. 4) is divided into A and B columns. A is a compartment in which the water of the upper sorting tank (2) comes down through the circulation lever with the tailings powder and is pumped together with the overflowed water. Khan was refilled with aggregates or conveyors with supplemental water to replenish the water consumed with compartment A with a small submersible pump (10). The water in compartment B was connected to the automatic pump level control sense (11) to keep the water level constant. The width of the A space is matched to the fork-lane bucket to facilitate the extraction of tailings.

As described above, with a volume of 73.2m3 (18.3㎡ wide * 4m high), the installation and construction of a simple wet sorting machine (Figure 7), which maximizes the efficiency of sorting and produces high-quality recycled aggregates, is groundbreaking.

The present invention is better suited to the new combination of existing technologies. Separation of soil using grazing feeder, selection of debris by manpower and wind, and then debris of debris aggregate by water (selection tank) could produce high quality recycled aggregate.

Drain-free transfer processing through the floated stainless steel mesh conveyor (Fig. 3: Initially installed cylindrical foreign substance ejector (Fig. 3), but it did not work well depending on the water level, foreign matter with the water conveyor) Sending phenomenon).

Transfers using a conveyor made of perforated and non-slip jaws to move aggregates in the sorting tank without water (Fig. 5).

The amount of tailings that settled on the bottom of the sorting tank was too high than expected, and after removing the sorting machine, the sorting machine was produced as before.

The overflow of the sorting tank was designed to automatically filter the remaining foreign matter and to automatically regulate the amount of water circulated through the circulation valve.

A magnet drum is added to the input conveyor to sort out the last scrap.

Drain-free transfer treatment of foreign matters through the stainless mesh strainer conveyor (Fig. 5) (3) (Slide the suspended matter from the charged gundam to the mesh net using the 0.5 hp small pump spray nozzle (5) to filter it well) In order to move the aggregate in the sorting tank without water, the aggregate transfer conveyor 4 with perforated and non-slip jaw is used. The pumped water (7) is a supplementary water of the sorting tank and the water spraying facility is made in the square of the upper corner of the history pyramid, like a spout (Fig. 6), to be sprayed toward the corner of the square pyramid, and the unrefined fine powder on the bottom circulates the valve (8). Designed to transfer well to tank A through The circulation lever serves to control well the amount of water being pumped and the amount of overflow (9) and overflow (9) so that the sorting tank water is always circulated to prevent the accumulation of tailings. Overflow adjusts the level so that foreign matter is well filtered through the mesh network, while remaining foreign matter is further sorted through this passage. The water tank (Fig. 4) is divided into A and B columns, where A is a tank in which the water of the upper sorting tank is lowered through the circulation valve with the tailings powder, and is pumped together with the overflowed water, and B is the supplemental water. The water consumed by burying in aggregate or conveyor, etc. serves as a small water pump (10) as a supplementary water to the A compartment, and the water level was always constant by connecting an automatic pump level control sense (11). The width of A space is made easy to extract the tailings powder according to the fork lane bucket.
