Description

Apparatus for separating sand and wastes from reclaimed stones}

The present invention relates to a construction waste treatment apparatus for sediment and foreign matter selection, which can be explained in more detail as follows.

With the redevelopment of the city, the dismantling of buildings and the repair of roads due to deterioration and deterioration of the buildings have increased, resulting in a large amount of waste such as waste concrete, waste cement or construction site waste.

Although such construction wastes have to be disposed of through an appropriate treatment system, they are caused by improper disposal such as illegal landfilling and illegal dumping, causing environmental pollution and various social problems.

Therefore, it is important to separate and dispose of unnecessary waste and recycle the remaining resources among large amounts of construction waste, which is important not only in terms of resource and energy saving but also in terms of environmental protection.

However, to date, no separate alternatives or structural systems for treating construction waste have been well established, so that construction wastes are not recycled despite the fact that they can be recycled to road substrates, subsidiary base materials, concrete aggregates and good urban foundations. I cannot afford it.

In general, the construction waste recycling and treatment system consists of a system for crushing construction waste, removing soil, metals, suspended solids and other wastes, and separating only useful recycled aggregates by required particle size. Such a system will be described as a method and apparatus for crushing construction waste, a method and apparatus for separating recycled aggregates by required particle size, and a method and apparatus for separating and removing garbage.

Methods and apparatuses for separating waste from construction wastes include using buoyancy of water and wind power depending on the difference between the weight of the recycled aggregate and the waste. The device using the buoyancy of water has the advantage that the recycled aggregate is clean and dust does not occur by washing with water, but it is difficult to manage the waste water and it is difficult to manage due to high maro rate and high risk of damage if water is on the machine. There was a problem that can not work frozen. On the other hand, the device using the wind has the advantage that there is no burden of waste water treatment, but there is a problem in that a scattering facility to remove the scattering dust generated by scattering dust.

A device for separating waste from recycled aggregates that can prevent or suppress scattering dust is disclosed in Korean Utility Model Registration Utility Model Registration No. 20-0204210.

Referring to Figure 1, the separation device for recycling the conventional waste aggregate is made of a crushed aggregate of a predetermined size using a grinder 10 and then supplied to the vibration smoothing device 14 by a conveying means such as a conveyor (12) Spread the crushed aggregate evenly.

Then, the free fall to be stored in the aggregate storage tank 18 through the reservoir conveyor 16, the blower 20 injects a constant speed of air from the lower side of the vibration smoothing device 14 to lighter paper than the crushed aggregate A piece of wood and the like were separated by a separation drum 22 installed near the end of the vibration smoothing device 14 to be separated and stored in the foreign matter storage tank 24.

However, in the case of the separation device for recycling such conventional waste aggregate, using the grinder 10 to crush the construction waste, and then to separate the waste and recycled aggregate through the apparatus of the post-process, Since it is processed by shredding irrespectively, not only the power consumption due to shredding is high but also its effectiveness in treating construction waste is not good.

On the other hand, it is also known to shred the construction waste provided from the hopper in the post-process without immediately shredding, but even in this case, the waste is processed and the remaining recycled aggregate It is somewhat difficult to distinguish and regenerate by particle.

Accordingly, the present applicant is a method for compensating for the disadvantages of various construction waste treatment systems, which are variously known, before selecting and crushing construction wastes supplied from the site, and then selecting the construction wastes first and then selecting them. It was proposed to separate the aggregates from different types of aggregates, but to select the soil from the firstly selected construction wastes and to recycle it as agricultural cover.

The purpose of the present invention for solving the above problems, before the crushing and sorting the construction waste supplied from the site, the first screening of construction waste and then the segregation of different particles by proceeding separately from the sorted and not selected To sort, but to provide a construction waste treatment apparatus for the sediment screening, so that only the soil was selected and recycled, among the first selected construction wastes. Thus, the selected soil is not mixed with the waste cone and cement components, unlike the waste soil generated in the conventional construction waste treatment plant, so there is no alkali (Cl) component, so it can be used as a cover material for farmland, so that soil contamination does not occur at all.

Soil sorting construction waste treatment apparatus 500 according to the present invention may be used alone to screen the soil having a particle size of about 22mm or less from the construction waste, but a part of the construction waste treatment system filed by the applicant It can be used as.

First, the configuration of the construction waste treatment apparatus 500 for the soil separation is as follows. Prior to the description, there are two configurations of sorting holes. The sorting holes for the construction waste treatment device for earth and sand sorting are called secondary sorting holes 516a, and the first screen 300 is sorted as a construction waste treatment system. The ball will be referred to as primary separation ball 300a.

According to the present invention, the construction waste treatment apparatus 500 for earth and sand sorting, a transport unit for transporting the selected construction waste through the primary screening hole (300a) of the first screen 300 of the construction waste treatment system shown in FIG. 510 and the secondary waste separation hole (516a) having a diameter of about 22 mm is formed in the circumferential direction, which is relatively smaller than the primary separation hole 300a in the circumferential direction. Cylindrical sorter 516 for sorting the soil 517 through the separate hole 516a, and a blower which is located at the rear end of the cylindrical sorter 516 and blows the blower air toward the construction waste discharged through the cylindrical sorter 516 ( 518 and a dust collector 520 positioned behind the cylindrical separator 516 to collect waste in the construction waste blown by the blower 518.

First and second transfer frames 512 and 514 are installed between the transfer unit 510 and the cylindrical separator 516 to introduce the construction waste transferred by the transfer unit 510 into the cylindrical separator 516 at a predetermined angle. It is.

The first transfer frame 512 is connected to the end of the transfer unit 510 which can be a conveyor to move the construction waste dropped from the transfer unit 510, the second transfer frame 514 is the first transfer frame ( The construction waste flowed along the first transfer frame 512 almost alternately with 514 to be introduced into the cylindrical sorter 516. Therefore, the second transfer frame 514 is disposed inclined at a predetermined angle with respect to the longitudinal direction of the cylindrical separator 516. The first and second transfer frames 512 and 514 are supported by separate brackets.

As described above, the second transfer frame 514 introduces the construction waste into the cylindrical sorter 516 at a predetermined angle rather than in the horizontal direction. At this time, if the construction wastes introduced into the cylindrical sorting unit 516 through the second transfer frame 514 are directly caught in the secondary sorting hole 516a of the cylindrical sorting unit 516, the earth and sand through the secondary sorting hole 516a. 517) cannot be screened. Thus, a section 516b in which the secondary separation hole 516a is not formed is formed in the inlet region of the cylindrical separator 516 so that the construction wastes are introduced into the cylindrical separator 516 through the second transfer frame 514. It is prevented to be pinched directly in the other hole 516a.

A funnel portion 516c is formed at the rear end of the cylindrical sorter 516 to collect and discharge the construction wastes that are not sorted through the cylindrical sorter 516. The discharged through the funnel portion 516c includes construction waste other than the earth and sand 517 and waste mixed with them. The end of the funnel portion 516c is located in the blowing path of the blower 518 to increase the blowing efficiency.

The dust collecting container 520 is located at the rear end of the cylindrical sorting unit 516 with a position and inclination such that the waste in the construction waste can be easily introduced by the blowing air from the blower 518.

The dust collector 520 generally has a rectangular duct shape, and an air discharge hole 520a through which the blowing air from the blower 518 is discharged is formed on the rear upper surface of the dust collector 520. The rear upper surface of the dust collecting container 520 in which the air discharge hole 520a is formed is inclined, and is formed perpendicular to the blowing direction of the blower 518 so that the blowing air can be easily discharged to the outside.

Inflowing into the dust collecting container 520 by the blowing air is waste that is not necessary among the construction wastes, and is moved to the rear of the dust collecting container 520 and then collected and disposed of in the waste receiving unit 530.

As a result, when using the construction waste treatment apparatus 500 for sediment sorting according to the present invention, it is possible to sort out the soil sand 517 of about 22 mm or less out of construction wastes, as well as construction wastes larger than 22 mm are moved to other places. The land can be reprocessed with soil, etc., which can be separated and cultivated to allow simple landfill, and the waste in the construction waste can be properly separated and disposed of.

On the other hand, if you do not use the construction waste treatment apparatus 500 for sewage sorting according to the present invention alone, but want to use as a configuration of the construction waste treatment system is applied to the system as shown in FIG.

Referring to FIG. 1, the construction waste treatment system includes a hopper 100 for storing and discharging construction waste, a feeder 200 for transferring construction waste discharged from the hopper 100 to a process back, and a feeder 200. Located in the rear of the process) to sort out the construction waste from the feeder 200 first, but the first screen 300, the first screen 300, the first screen 300 is formed in a predetermined size on the plate surface is not sorted Primary waste crusher 400 for crushing the construction waste relatively smaller and the construction waste of the relatively small particles selected through the primary screening hole (300a) of the first screen 300 to the waste and soil 517 Construction waste shredded in construction waste and primary crusher 400 having a larger particle size compared to the soil 517 that was not selected in the construction waste treatment device 500 for sediment sorting and the construction waste treatment device 500 for sorting soil and foreign matter. Line separating waste into different sized aggregates and trash The second screen 600 and the secondary crusher 700 and the tertiary crusher 800 located in the rear of the process of the second screen 600 to again crush the construction waste that is not sorted through the second screen 600 ).

Construction wastes are accommodated in the relatively large funnel-shaped hopper 100. As described above, the construction waste refers to waste concrete or waste cement or construction waste generated at the construction site as the dismantling of buildings and repair of roads increase. At the bottom of the hopper 100, a discharge port 100a through which construction waste is discharged to the first screen 300 is formed.

The first screen 300 is located behind the process of the hopper 100 serves to sort the construction waste discharged through the discharge port (100a) of the hopper 100. On the plate surface of the first screen 300, a primary separation hole 300a through which a construction waste having a size of at least 55 mm or less is selected from among construction waste having various particle sizes.

The primary crusher 400 crushes construction wastes having a size of, for example, 55 mm or more that are not sorted through the primary screening holes 300a of the first screen 300. The shredded construction wastes are directed to the second screen 600 behind the process.

The second screen 600 separates and sorts the construction waste crushed by the primary crusher 400 into aggregate and rubbish having different sizes. Aggregates of different sizes that are screened by the second screen 600 are stone powder (600a), 25mm aggregate (600b), 40mm aggregate (600c). Accordingly, the second screen 600 is divided into a plurality of different screens, respectively. In the process of selecting the 25mm aggregate 600b and the 40mm aggregate 600c, the fins 610 and 620 are used, respectively. That is, when the 25mm aggregate (600b) and 40mm aggregate (600c) in the process of sorting (휀, 610, 620) by the operation of the waste other than the 25mm aggregate (600b) and 40mm aggregate (600c) is collected in a separate waste container (630) do.

The construction waste that is not screened by the second screen 600 into the stone powder 600a, the 25mm aggregate 600b, and the 40mm aggregate 600c is transferred to the secondary crusher 700 and the tertiary crusher 800 through separate processing. Headed. At this time, the air blower 640 is operated. Among the construction wastes directed to the secondary crusher 700 and the tertiary crusher 800, the waste is collected and disposed again in the waste accommodating part 630.

On the other hand, the construction waste of particles having a relatively large particle size compared to the soil 517 which is not sorted by the soil 517 in the construction waste treatment apparatus 500 for sediment and foreign matter sorting is sent back to the second screen 600 together with the second. Through the screen 600 is again screened into stone powder (600a), 25mm aggregate (600b), 40mm aggregate (600c).

The method of utilizing the earth and sand having the configuration and the construction waste treatment apparatus 500 for sorting foreign matter together in the construction waste treatment system will be described in series.

First, construction wastes collected at various construction sites are collected in the hopper 100. After collecting, the feeder 200 is supplied to the feeder 200 through the outlet 100a of the hopper 100, and then moved to the rear of the process by the feeder 200 to the first screen 300.

Construction waste transferred to the first screen 300 is classified as having a size of 55 mm or less through the primary screening hole 300a formed in the first screen 300 and not. Construction waste of less than 55mm is directed to the construction waste treatment device 500 for sediment and foreign matter, while construction waste that does not pass through the primary screening hole 300a of the first screen 300 is directed to the primary crusher 400. . At this time, the worker may separate the scrap metal and garbage by manpower (see A of FIG. 1).

The construction waste of 55 mm or less that has passed through the primary screening hole 300a of the first screen 300 is transferred through the transfer unit 510 of the construction waste treatment apparatus 500 for soil and foreign matter selection, and then, the first transfer frame ( After falling to the second transfer frame 514 via 512 is introduced into the cylindrical separator 516 at a predetermined angle. Since the section 516b in which the secondary sorting hole 516a is not formed is formed in the inlet region of the cylindrical sorting machine 516, the construction wastes introduced at a predetermined angle through the second conveying frame 514 are secondary sorting holes ( 516a) is blocked.

Next, the cylindrical sorter 516 rotates to sort out the construction wastes introduced therein. Since the secondary sorting hole 516a having a diameter of about 22 mm is formed on the circumferential surface of the cylindrical sorting machine 516, the construction waste that is sorted and dropped through the secondary sorting hole 516a is classified as the soil 517 of 22 mm or less. Collected separately and recycled.

Construction wastes that have not been sorted through the secondary sorting hole 516a of the cylindrical sorter 516 are discharged through the funnel portion 516c of the cylindrical sorter 516. At this time, the blower 518 is operated, and only the relatively light waste of the construction wastes is introduced into the dust collecting container 520 by the blowing air.

Blowing air introduced into the dust collecting container 520 together with the waste is discharged through the air discharge hole 520a formed on the inclined surface of the rear end of the dust collecting container 520, and the garbage moves to the rear of the dust collecting container 520. It is collected in the waste accommodating part 530 and discarded. At this time, the size of the particles is 22mm or more of construction waste is not affected by the blowing air, the construction waste discharged through the cylindrical separator 516 as it is falling and sent to the second screen 600 together.

On the other hand, construction waste of 55mm or more that does not pass through the primary screening hole (300a) of the first screen 300 is directed to the primary crusher 400 through the first screen (300). Then, it is crushed by the primary crusher 400 and then directed to the second screen 600. Before heading to the second screen 600, the worker may separate scrap metal and waste by manpower (see FIG. 1B).

The construction waste crushed in the primary crusher 400 is selected as the stone powder 600a, 25mm aggregate 600b, 40mm aggregate 600c of different sizes through the second screen 600. At this time, in the process of selecting the 25mm aggregate 600b and the 40mm aggregate 600c, the fins 610 and 620 are operated. That is, when the 25mm aggregate (600b) and 40mm aggregate (600c) in the process of selecting the 휀 (610, 620), the unnecessary waste other than the 25mm aggregate (600b) and 40mm aggregate (600c) is collected in a separate waste container 630 Discarded.

In the second screen 600, the construction waste that is not sorted by the stone powder 600a, the 25mm aggregate 600b, and the 40mm aggregate 600c is directed to the secondary crusher 700. Before heading to the secondary crusher 700, the worker can separate scrap metal and waste by manpower (see C of FIG. 1), in which case the air blower (640) is operated to only the construction waste of the shredding target 2 The crusher 700 and the tertiary crusher 800 are sent. Of course, the waste separated by the air blower 640 is collected in the waste accommodating unit 630 and disposed of. While moving from the secondary crusher 700 to the tertiary crusher 800, the worker may separate scrap metal and waste by manpower (see D in FIG. 1).

The construction waste crushed by the secondary crusher 700 and the tertiary crusher 800 is fed back to the second screen 600, and then, the second and second stones 600 of the different sizes of stone powder 600a, 25mm aggregate (600b), 40mm aggregate (600c) to be screened. At this time, in the process of operating the air blower 640, the secondary crusher 700 and the tertiary crusher 800 may be a separate spray pump.

As such, according to the present invention, before crushing and sorting the construction waste supplied from the site, the first screening of the construction waste, and then the screening and the non-selected to proceed separately to screen the aggregate of different particles, 1 Among the construction wastes selected as cars, only the soil 517 can be selected and recycled as uncontaminated farmland cover material.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

As described above, according to the present invention, before crushing and sorting the construction waste supplied from the site, the construction waste is first screened, and then the screening and the unscreened are separately selected to be classified into aggregates of different particles. In particular, there is provided a construction waste treatment apparatus for screening soil and foreign matters, which enables the recycling of uncontaminated farmland soils by selecting only soils, among the firstly selected construction wastes.
