BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction waste sorting apparatus using a unit volume mass and a recycling aggregate production method using the same,

The present invention relates to a construction waste sorting apparatus using a unit volume mass and a method for producing recycled aggregate using the unit mass volume. More specifically, the present invention relates to a construction waste sorting apparatus using unit masses, If the unit mass of the measured construction waste is greater than or equal to the reference value, it is directly applied to the recycled aggregate. If the unit volume mass is less than the reference value, it is sent again to the impact crusher, which is the bottom crusher, The present invention relates to a construction waste sorting apparatus and a recycling aggregate production method using the same, which are capable of significantly improving the quality of recycled aggregate produced from construction waste, will be.

In this case, the unit volume mass is a value obtained by dividing the mass of the recycled aggregate by the volume of the filled container, and includes the water content of the natural state read from the measuring apparatus installed on the site. The dry mass unit volume is obtained by drying the recycled aggregate in an oven And the measured value is filled.

Where G: mass of recycled aggregate (Kg)

       V: Volume of the container (L)

Also, the unit volume mass of the recycled aggregate varies depending on the quality characteristics such as absolute dry density, particle size and porosity of the aggregate, and thus the recycled aggregate having a high unit volume is excellent in quality.

Construction of various construction and civil engineering works Industrial wastes have increased sharply, mainly due to aging of buildings and urban buildings, revitalization of reconstruction, dismantling of structures, and so on.

Generally, the term "construction waste" refers to soil, sand, gravel, earth or sand mixed with waste materials, waste materials, etc., concrete blocks, waste wood, asphalt concrete blocks and construction sludge, One of the main characteristics is that most of the construction wastes are made of inorganic materials and are harmless to the human body and that they are discharged in a mixed state of various wastes and are complicated and difficult to handle. It provides the cause of government and industry indifference about waste disposal.

The above indifference has been accompanied by a waste of valuable resources, which has led to deterioration of the quality of the recycled aggregate, and the utilization of such recycled aggregate has been mostly used as substitute for the soil, such as the embankment, the soil and the landfill.

Therefore, it is necessary to actively promote minimization of environmental pollution, replacement of scarce resources, and cost reduction in the whole construction industry by enabling practical recycling through management of such waste.

According to the statistics of the Ministry of Environment in 2006, the annual amount of construction waste in Korea is 61.8 million tons / year, and its recycling rate is 97%, which is relatively high. However, due to limitations in processing technology and recycling field, There is a low problem.

The construction industry, which accounts for the largest amount of construction waste, is construction waste, which accounts for about 79% of the construction waste. However, mixed waste of various types and characteristics is mixed in construction waste, and mixed waste The recycled aggregate is produced as a single continuous process without taking into consideration the characteristics of the imported waste, so that it is difficult to obtain homogeneous quality and efficient treatment can not be achieved.

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

Therefore, it is necessary to develop recycling aggregate production technology using screening technology of recycled aggregate considering the characteristics of construction waste materials and recycling aggregate production technology using this technology. That is, countermeasure technology is needed to enhance the processing technology of construction waste and recycle it for optimum use It is true.

While the sample volume of the unit volume mass is being filled in the unit volume mass measurement container 9 as described above, the control board 18 controls the first load cell (not shown) supporting the bottom surface of the unit volume mass measurement container 9 11, the total mass of the recycled aggregate change amount currently filled in the unit mass measurement container 9 is input in real time, and the total weight change value for the unit volume mass measurement container 9 and the recycled aggregate is used (D (mass) of the recycled aggregate (G; Kg) / volume (V; L) of the vessel) is continuously calculated to continuously determine whether the changed unit volume mass is equal to the predetermined initial unit volume mass .

In this way, while the sample circulating aggregate is filled in the unit volume mass measurement container 9, the output signal of the first load cell 11 is received in real time, and the total weight change value of the unit volume mass measurement container 9 and the recycled aggregate If the calculated unit volume mass equals the preset initial unit volume mass, the control panel 18 recognizes that a desired amount of sampling circulating aggregate is filled in the unit volume mass measurement container 9, 10 is moved in the opposite direction to the outside of the small hopper 7 along the upper surface of the container movement supporting rail 64 as shown in FIG.

At this time, when the unit volume mass measurement container 9 is transported to the outside of the small hopper 7 along the upper surface of the container movement support rail 64 in correspondence with the operation direction of the container transport cylinder 10, A part of the sampling circulating aggregate accumulated up to the upper surface of the unit volume mass measurement vessel 9 is flattened by the action of the horizontal surface forming member 8 provided at one side of the bottom of the hopper 7, The upper surface of the unit volume mass measurement container 9 has a planar state aligned with the upper surface of the unit volume mass measurement container 9 in the vertical direction.

When the unit volume mass measurement container 9 is moved outward by a predetermined distance from the small hopper 7 while the upper surface of the sampling recycle aggregate is flattened as described above, And has a shape that is raised on the upper surface of the load cell 12.

When the unit volume mass measurement container 9 is mounted on the upper surface of the second load cell 12 as described above, the control unit 18 includes the unit volume mass measurement container 9 through the second load cell 12, And the total weight of the sampling recycled aggregate filled in the inside is measured.

Thereafter, in the control panel 18, the unit volume mass of the sampling circulating aggregate filled in the current unit volume mass measurement container 9 calculated using the weight measured through the second load cell 12 is calculated, The unit volume mass and the target unit mass mass are compared with each other.

As a result of the comparison between the unit volume mass and the target unit volume mass for the sampling circulated aggregate in the control panel 18 as described above, the volume of the unit recycle aggregate calculated using the weight for the sampling recycle aggregate measured through the second load cell 12 When the mass is equal to or more than the target unit mass, the discharge direction determination gate 14 is determined as the acceptable product circulating aggregate and blocks the bottom opening of the large hopper 13 through the discharge direction gate cylinder 15, (For example, a counterclockwise direction as shown by the imaginary line in Fig. 1) to discharge the circulating aggregate in the large hopper 13 containing one lot to the acceptance conveying conveyor 16 side.

Therefore, one lot of the accepted product recycled aggregate discharged from the large hopper 13 is automatically transferred to the acceptable storage yard through the accepted product conveying conveyor 16. [

On the other hand, as a result of comparing the unit volume mass and the target unit volume mass for the sampling recycled aggregate in the control panel 18, the volume of the unit recycle aggregate calculated using the weight for the sampling recycle aggregate measured through the second load cell 12 When the mass is less than the target unit volume mass, it is determined that the rejected product is a recycled aggregate and the discharge direction determination gate 14, which blocks the bottom opening of the large hopper 13 through the discharge direction gate opening / closing cylinder 15, For example, clockwise as shown in Fig. 2) so as to discharge the circulating aggregate in the large hopper 13 containing one lot to the conveying conveyor 17 side.

Therefore, one lot of rejected product circulated aggregate discharged from the large hopper 13 is automatically transported to the impact crusher 4 side via the transport conveyor 17, and the rejected product circulated aggregate, which is transported toward the impact crusher 4 side, (4), and then flows back to the small hopper (7) through the construction waste supply conveyor (5). Then, through the above-described series of processes, whether the product is rejected or rejected is judged again.

At this time, the initial unit volume mass, the target unit volume mass, and the unit volume mass measurement interval (unit: minute) are set such that the circulation aggregate property of the building waste to be subjected to the screening work is changed, When the volume mass is judged as a result of the successive recycled aggregate or rejected recycled aggregate, it is possible to lower or raise the preset value to the desired value, respectively.

As a result of continuously discriminating whether a rejected or rejected product is a recycled aggregate of construction waste for each lot through the present invention, it is judged that the shape of the recycled aggregate of the recycled aggregate of recycled aggregate is very good when the product lot continuously passes. The worker re-sets the target unit volume by relatively increasing the mass of the target unit through the key input unit 181 provided in the control panel 18 and repeats the selection by the above procedure. And it is possible to use the recycled aggregate having a very high quality due to another yard.

In the present invention, it is judged that the quality of the recycled aggregate of construction waste recycled aggregate is very bad when the production lots are continuously rejected as a result of determining whether the rejected or rejected aggregate of construction waste is in each lot. , The worker re-sets the target unit mass by relatively lowering the target unit mass via the key input unit 181 provided in the control panel 18 and repeats the process of re-selecting and re-conveying through the above-described procedure, It can be used as a recycled aggregate of high quality and recycled aggregate. It can also be used as a recycled aggregate of high quality, or mixed with high quality recycled aggregate to be used as recycled aggregate of desired quality. .

As described above, according to the present invention, it is possible to produce recycled aggregate of appropriate quality according to the characteristics of imported construction waste, or to produce recycled aggregate homogeneously produced by each lot according to the requirements of the customers, It is possible to produce recycled aggregate of desired quality by mixing the other yard fields with each other.
