Description

Apparatus for separating recycled gravel from waste building products}

The present invention relates to a recycled aggregate sorting device for building wastes applied to the process of extracting recyclable gravel and sand from the building wastes generated when the building is torn down for the purpose of reconstruction or repair of the building.

Conventionally, a sorting device for the same purpose as the present invention has been developed and widely used.

The sorting device handled in the present invention is applied to a widely known regeneration process as shown in FIGS. 6A and 6B, and regenerates by recycling gravel and sand from concrete solidified in mortar by crushing construction waste. Aggregate extraction process.

Looking at the conventional general process as described above in detail as follows.

First process; The usual foreign matter is removed by the input process (A) for supplying construction waste.

Second process; It is a primary grinding process (B) that grinds relatively large building wastes to a diameter of about 10 cm.

This process exposes large pebbles and rebars that are firmly contained in Maltar.

Third process; As a primary metal removal process (C) for removing metals included in concrete, metals having a relatively large size are selected and removed.

Fourth process; The washing step (D) to remove the dust generated in the second step includes a step of weakening the strength of the mortar forming the concrete.

Fifth process; In the fourth process, the secondary grinding process (E) is performed to grind the concrete, which is weak in strength, to be smaller, so that gravel and sand are sorted.

In this crushing process, sand and various sizes of gravel included in the mortar are selected by the crushing shock.

Sixth process; In the above process, the secondary metal removal process (F) removes small metals contained in the concrete crushed to a smaller size.

7th process; An important process to which the present invention is applied is a screening process (G) for sorting the gravel and sand that have been crushed and selected in all processes.

That is, the first screen through which large gravel can pass, the second screen through which small gravel passes, and the third screen through which sand passes, are arranged at predetermined intervals above and below to sort the gravel and sand passing from the upper side. It should be pit.

Eighth process; In the seventh step, a regrinding process (H) for recovering and crushing again the larger construction waste that has not passed through the first screen passing large gravel.

In this process, most of the reconstructed building waste can pass through the first screen to filter out large gravel, and in some cases, to recover the collected building waste.

The series of known processes as described above can be improved through the device or process of a more effective process as a process that can extract the recycled aggregate most efficiently from the construction waste.

Accordingly, the present invention relates to an apparatus for effectively performing the screening process (G), which is the seventh process, and includes a utility model registration No. 301996 and a utility model registration No. 302005 registered in advance.

In the conventional pre-registered design as described above, the configuration and principle of selecting the aggregate by the screen structure that is gradually smaller from the larger through-hole inside the case vibrated by the vibration device is the same.

However, the material of the screen is mainly made of hard steel plate, which causes the construction waste to be thrown out of the device by vibration, and the maintenance process is complicated and long time use such as replacing the worn screen as a whole. There was a problem that productivity is lowered.

The present invention has been devised to solve the conventional problems as described above, the screen is made of a rubber material inserted into the core material of the lattice-shaped inside to excellent tensile force as a material having elasticity and cushion, even when installed in the case It is installed in 3 pieces, and it consists of a sorting device that is fixedly supported by 2 center press plates and 2 edge press plates, and when only part is worn out, only the pieces are replaced so that maintenance can be managed very quickly and at low cost. The purpose is to provide a sorting device.

On the upper part of the supporting frame 23 as described above, the first to third screens 20, 30 and 40 divided into three parts are raised, and then the middle part is fixed by using two central pressure plates 21, and the edges are two edge pressure plates. (22) is a sorting device (10) having a configuration in which the first to third screens (20, 30, 40) are fixed and supported by compression.

The first to the third screen (20, 30, 40) is a material with elasticity and cushioning is composed of a rubber material inserted into the core of the lattice shape to excellent tensile force, even when installed in a case 3 Composed of a sorting device 10 configured to be fixed and supported to be pressed by two central pressing plate and two edge pressing plate, if only part is worn, the maintenance can be managed very quickly and at a low cost.

In the drawings, reference numeral "50" is an input conveyor, "20b" is a recovery conveyor, "30b" is a large gravel conveyor, "40b" is a sand conveyor, "40c" is a sand hopper.

Referring to the operation of the present invention configured as described above are as follows.

1, 4 to 6a, 6b through the input conveyor 50 located on the upper side through the secondary grinding process (E) of the fifth process and the secondary metal removal process of the sixth process ((F After finishing), the second milled waste concrete is dropped on the first screen 20.

The waste concrete dropped as described above is rolled along the slope because it is inclined in the longitudinally open direction.

In the process of rolling down as described above, the whole screening device 10 including the screens 20, 30, 40 is shaken by a constant width by the case 11 vibrating by the vibration device 15.

As described above, the building waste put into the upper part of the sorting device 10 vibrated by shaking is rolled down while being evenly dispersed in a tangled state.

As described above, the pieces having a diameter of about 50 mm or less in the process of rolling down at a predetermined speed by a constant vibration in the upper part of the case 11 are sieved holes of the circular first screen hole 20a drilled in the first screen 20. Through the first screen is made by falling to the upper portion of the second screen 30 located below.

On the other hand, a relatively large building waste having a diameter of 50 mm or more that cannot pass through the sieve hole of the first screen hole 20a of the first screen 20 in the first screening process is installed at the lower side of the side plate 11b. It is moved to the regrinding process (H) by the recovery conveyor (20b).

As described above, the building waste regrind in the regrinding process (H) passes through the metal removal device located in the middle and is loaded into the input conveyor 50 to be introduced into the sorting device 10.

Therefore, as the above regrinding process (H) is repeated, most of the building waste is selected by the first screen (20).

However, building wastes that are not screened even after multiple regrinding may be disposed of by separate manual operations, and in some cases, if the main material of the building wastes is desired to be disposed of, it may be disposed of immediately without regrinding.

In addition, pieces having a diameter of about 25 mm or less among construction wastes having a diameter of 50 mm or less dropped on the second screen 30 are lowered through a sieve hole of a circular second screen hole 30a drilled in the second screen 30. Building wastes dropped on the upper part of the third screen 40 located in the building and not passed through are dropped into the large gravel conveyor 30b and transferred to the yard position. The size of the large gravel having a diameter of about 25 to 50 mm is Mostly.

In addition, among the construction waste of 25 mm or less dropped on the upper portion of the third screen 40, those having a diameter smaller than about 9 mm are located in the bottom hopper 40c which is passed through the sieve hole of the circular third screen hole 40a. ) Is put into the sand conveyor (40b) to be moved to the yard as these are mostly small sand.

In addition, the building waste which does not pass through the screen hole of the third screen hole 40a is dropped into the small gravel conveyor 40a installed at the end as small gravel and moved to the yard. Most of it is gravel.

As described above, the action of sorting by the size of the circular first to third screen holes 20a, 30a and 40a through the sieve holes perforated in each of the first to third screens 20, 30 and 40 is applied to the construction waste. Sorted by large gravel and small gravel and sand included.

Aggregates selected as described above do not cause any problems in strength even when recycled because there is no deformation of the material.

The sorting device 10 of the present invention, which acts as described above, is fixed to the first to third screens 20, 30, and 40 by using two central pressing plates 21 as shown in FIG. 2A. And the edge is configured to support by pressing and pressing the two edge pressing plate 22, which is to replace the worn pieces only when a portion of the wear out of use to reduce the maintenance cost and to repair quickly.

In addition, the horizontal support bars 24 installed in the transverse direction at regular intervals in the middle of the support frame 23 supporting each of the first to third screens 20, 30, and 40 are elastic first to third screens. It prevents deflection of (20, 30, 40) as well as supports each connection part.

In addition, a pair of longitudinal support bars 25 side by side have a function to more firmly support the state in which the three rubber screens are connected, and has a function to prevent being pushed by the building wastes put in a large amount.

The rubber screen of the present invention can be used in various pieces apart from those shown in the drawings as necessary.
