Construction waste sorting apparatus using unit volume mass and method for producing recycled aggregate using the same}

The present invention relates to a construction waste sorting apparatus using a unit volume mass and a method for producing circulating aggregate using the same. More specifically, the unit waste mass is measured by lot in a natural state of construction waste, and compared with a reference value for each lot. If the unit volume mass of the measured construction waste is greater than or equal to the standard value, apply it to the circulating aggregate immediately.If the unit volume mass is less than the standard value, send it to the impact crusher, which is the lowest crusher, and re-crush the unit volume mass. Through the construction waste sorting device using the unit volume mass and the method for producing the recycled aggregate using the same, it is possible to greatly improve the quality of the recycled aggregate produced from the construction waste and to greatly increase the recycling rate of the construction waste. will be.

At this time, the unit volume mass is the value divided by the volume of the container filled with the mass of the circulating aggregate, and includes the moisture content of the natural state read by the measuring device installed in the field, and the dry unit volume is the container by drying the circulating aggregate in an oven. Fill in the measured value.

Where G is the mass of circulating aggregate (Kg)

       V: volume of container (L)

In addition, the unit volume mass of the circulating aggregate is changed according to the quality characteristics such as absolute dry density, particle size and porosity of the aggregate, so that the circulating aggregate having a high unit volume mass is excellent in quality.

The construction industry wastes of various constructions and civil works show a sharp increase, mainly due to the redevelopment, revitalization of reconstruction, and the dismantling of structures, which are actively progressed due to the aging and deterioration of urban and local buildings.

In general, construction waste refers to soil, sand, gravel, earth or mixed soil mixed with rubbish and waste materials, concrete lumps, waste wood, asphalt concrete lumps, and construction sludge. One of the main characteristics is that most of the construction wastes are composed of inorganic materials, which are harmless to the human body, and that various kinds of wastes are discharged in a mixed state, and their treatment is complicated and difficult. It is said to provide the cause of indifference between the government and industry regarding waste disposal.

The indifference was accompanied by the waste of valuable resources, and caused the deterioration of the quality of the recycled aggregate was made, the utilization of such recycled aggregates, such as soil, cover, and landfill, but was used only for the soil.

Therefore, it is necessary to actively minimize the environmental pollution, replace the scarce resources, and reduce the overall cost of the construction industry by enabling the actual recycling through the management of such wastes.

Meanwhile, according to the 2006 Ministry of Environment statistics, the annual generation amount of construction waste in Korea is 61.8 million tons / year, and its recycling rate is 97%, which is relatively high, but due to the limitations in the treatment technology and recycling field, the economic and efficiency of resourceization is There is a low problem.

The largest proportion of construction wastes is the construction wastes, which account for about 79%. However, construction wastes contain mixed wastes of various types and characteristics, and such mixed wastes brought into intermediate treatment plants. Since the properties of the incoming waste is good, it is produced as a circulating aggregate by a single continuous process without considering the bad, there is a problem that it is difficult to ensure homogeneous quality and efficient treatment.

However, the intermediate treatment of construction waste consists mainly of crushing by crusher and sorting by wind, magnetic force and manpower. Also, equipment for removing foreign substances such as cement paste has been developed and applied. There is a problem in that it is not possible to produce a homogeneous quality recycled aggregates because the quality control is not implemented.

Therefore, it is necessary to develop the technology for sorting recycled aggregates in consideration of the characteristics of construction wastes and the technology for producing recycled aggregates using them, that is, to improve the treatment technology of construction wastes and to take measures to recycle them for optimal use. It is true.

When the input of various masses and times is completed as described above, the control panel 18 sequentially drives the construction waste supply conveyor 5 through the jaw crusher 1, the double jaw crusher 2, and the cone crusher 3. After crushed by the impact crusher (4) is finally crushed and discharged construction waste circulation aggregate discharged to the small hopper (7) side through the construction waste supply conveyor (5).

Subsequently, for every predetermined unit volume mass measurement time set by the control panel 18, the cylinder transporting cylinder 10 is operated so that the unit volume mass measuring container 9 is placed at the bottom of the small hopper 7 as shown in FIG. 1. While being positioned at the same time as the upper surface of the first load cell 11 to be moved along the upper surface of the container moving support rail 64, a portion of the circulating aggregate discharged from the small hopper 7 is measured by the unit volume mass The sample is filled into the unit volumetric weighing container 9.

As described above, while the unit aggregate mass measurement container 9 is filled with the circulating aggregate sample for unit volume mass measurement, the control panel 18 supports the first load cell supporting the bottom surface of the unit volume mass measurement container 9. 11) through the real-time input of the total weight of the circulating aggregate change, including the unit volume mass measuring vessel (9) in real time to use the total weight change value for the unit volume mass measuring vessel (9) and circulating aggregate Continue to calculate unit volume mass (D = mass of recycled aggregate (G; Kg) / volume of container (V; L)), and continuously determine whether the unit volume mass that is changed is equal to the preset initial unit volume mass. .

As such, while the sampling circulation aggregate is filled in the unit volume mass measuring vessel 9, the output signal of the first load cell 11 is received in real time, and compared to the total weight change value of the unit volume mass measuring vessel 9 and the circulation aggregate. When the calculated unit volume mass is equal to the predetermined initial unit volume mass, the control panel 18 recognizes that the unit volume mass measuring container 9 is filled with a desired amount of sampling circulation aggregate, and the container transfer cylinder ( 10) is operated in the opposite direction to the outside of the small hopper 7 as shown in Figure 2 along the upper surface of the container moving support rail 64.

At this time, when the unit volume mass measuring container 9 is transported to the outside of the small hopper 7 along the upper surface of the container moving support rail 64 in correspondence with the operation direction of the container transport cylinder 10, A part of the sampling circulation aggregate accumulated up to the upper surface of the unit volume mass measuring container 9 is cut flat by the cutting action of the horizontal surface forming member 8 provided on one side of the bottom part of the hopper 7 so that the sampling circulation aggregate is flattened. The upper surface of 를 has a planar state coincided in the vertical direction with the upper surface of the unit volume mass measuring container 9.

On the other hand, as described above, when the upper surface of the sampling circulating aggregate is flattened and the unit volume mass measuring container 9 is moved outward by a predetermined distance from the small hopper 7, the unit volume mass measuring container 9 is arranged in a second manner. It has a form raised on the upper surface of the load cell 12.

When the unit volume mass measuring container 9 is placed on the upper surface of the second load cell 12, the control panel 18 includes the unit volume mass measuring container 9 through the second load cell 12. The total weight of the sampling circulation aggregate filled inside is measured.

Subsequently, the control panel 18 calculates the unit volume mass for the sampling circulation aggregate filled in the current unit volume mass measuring container 9 calculated using the weight measured by the second load cell 12, and then calculates the unit volume mass. The calculated unit volume mass and the target unit volume mass are compared with each other.

As a result of comparing the unit volume mass and the target unit volume mass of the sampling circulation aggregate in the control panel 18 with each other, the unit volume calculated using the weight of the sampling circulation aggregate measured through the second load cell 12. If the mass is equal to or greater than the target unit volume mass, the discharge direction determination gate 14 which judges that the end product circulation aggregate and blocks the opening of the bottom surface of the large hopper 13 through the discharge direction gate opening and closing cylinder 15 Rotate in one direction (for example counterclockwise as in the imaginary line of Figure 1) to discharge the circulating aggregate in the large hopper 13 containing one lot to the side of the conveyance of the conveyed product 16.

Accordingly, one lot of the passed product circulating aggregate discharged from the large hopper 13 is automatically transferred to the accepted product storage yard via the passed product conveying conveyor 16, and is stacked.

On the other hand, as a result of comparing the unit volume mass and the target unit volume mass for the sampling circulation aggregate in the control panel 18, the unit volume calculated by using the weight for the sampling circulation aggregate measured through the second load cell 12 If the mass is less than the target unit volume mass, it is judged as a rejected aggregate circulating aggregate and the discharge direction determination gate 14 blocking the bottom opening of the large hopper 13 through the discharge direction gate opening and closing cylinder 15 is moved in the other direction ( For example, it rotates in a clockwise direction as shown in FIG. 2 to discharge the circulating aggregate in the large hopper 13 containing one lot to the conveying conveyor 17 side.

Accordingly, one lot of rejected circulating aggregate discharged from the large hopper 13 is automatically conveyed to the impact crusher 4 side through the conveying conveyor 17, as well as the reject circulated aggregate conveyed to the impact crusher 4 side is the impact crusher. After being crushed again through (4), it is flowed back to the small hopper 7 side through the construction waste supply conveyor 5, and then judged again as a pass or fail product through the above-described series of processes.

At this time, the initial unit volume mass, the target unit volume mass, and the unit volume mass measurement interval (unit: minutes), the characteristics of the circulating aggregate of the construction waste to be input to the sorting operation is changed or the unit of the sample circulating aggregate in the control panel 18 When judging the volume mass, it is possible to reset the predetermined value by raising or lowering the preset value to the desired value, if it is judged continuously as a circulating aggregate or rejected circulating aggregate.

On the other hand, according to the present invention as a result of continuously determining whether the lot or the pass for the construction waste recycled aggregate for each lot, if the production lot is passed continuously, it is determined that the characteristics of the recycled construction waste recycled aggregate is very excellent, If the operator resets the target unit volume mass relatively upward through the key input unit 181 provided in the control panel 18, selects it again and again through the above-described procedure, and recognizes it as a higher-quality recycled aggregate. It is possible to use the recycled aggregate with high quality because it is stored in another yard.

In addition, according to the present invention as a result of continuously determining whether the lot or the pass for the construction waste recycled aggregate for each lot, if the production lot is continuously rejected, it is determined that the properties of the recycled construction waste recycled aggregate is very poor If the operator fails, despite the fact that the target unit volume mass is reset relatively downward through the key input unit 181 provided in the control panel 18, and the screening and retransmission is repeated through the above-described procedure. It can be used as a recycled aggregate of the desired quality by mixing it with a high-quality recycled aggregate or by mixing it with a high-quality recycled aggregate by transferring it to another yard that recognizes it as a recycled aggregate with only high quality and only rejects it. .

In this way, if the present invention is applied, it is possible to produce recycling aggregates of appropriate quality for each lot according to the characteristics of imported construction waste, and after homogeneously produced recycling aggregates are collected by lot for each yard, and according to the demand of the yard, respectively. Different yards can be mixed with each other to produce recycled aggregates of the desired quality.
