The present invention relates to a construction waste treatment apparatus that separates and sorts out concrete fragments and foreign substances that are crushed and discharged by a crusher in such a manner as to be crushed and discharged in an elongated or tattered form.

Many structures, such as bridges, roads, and other buildings, which have been created in the process of urbanization and industrialization, are gradually aging over the years, and in recent years, reconstruction and redevelopment has been actively promoted in many regions to improve the living culture. have.

Many construction wastes are generated in the process of dismantling, reconstruction, and redevelopment of old structures. If the construction wastes are reclaimed, landfills are not only difficult to secure, but also have a high cost of landfills and seriously affect the environment.

Accordingly, various measures have been taken in each country to treat construction waste in two aspects: protection of natural environment and recycling of resources. In Korea, many treatment devices for construction waste have been developed.

Construction wastes include earth and sand, construction wastes including waste concrete, waste asphalt, waste bricks, waste tiles, waste stones, waste and waste blocks, waste woods, waste synthetic resins, metals such as rebar, Waste papers, waste glass, sludge waste fibers, incineration residues and the like can be divided into mixed wastes.

As such, construction wastes containing various wastes are separated into landfill, incineration, and recycling through treatment.In recent years, construction wastes, which occupy a considerable portion of waste, are aggregated into various structures or aggregates. There is a plan to increase the recycling of waste by recycling for use.

In order to recycle waste concrete in construction waste, a method of crushing waste concrete using a concrete crusher is used. However, in general, waste concrete often contains foreign materials such as wood, non-combustible materials, heat-resistant materials, solidified waste synthetic resins, gypsum board panels with fabrics as a supporting means, and concrete pieces and foreign materials. Vibration screens, etc. are used to sort, but there is a problem that the sorting of concrete fragments and foreign matters is not properly made.

The features, advantages, preferred embodiments, and the like of the present invention are described in detail below with reference to the accompanying drawings.

1 is an overall schematic view showing the overall configuration of the construction waste treatment apparatus according to the present invention.

Referring to FIG. 1, a construction waste treatment apparatus according to the present invention includes a cone crusher 10 for crushing construction waste such as stone, and first, second and third conveyors 50 for conveying crushed or sorted construction waste. , 60, 70), consisting of a cylindrical screen (30) for sorting the construction waste crushed by the crusher (10) with stones such as stone and wood chips. An auxiliary support 52 is installed between the first conveyor 50 and the cylindrical screen 30 so that the foreign matter 22 and the concrete fragments 24 transferred from the first conveyor 50 enter the cylindrical screen 30. To be committed.

In the case of crushing the waste concrete mass 20 in the construction waste with the cone crusher 10 (in the present invention, a mill crusher), the waste concrete pieces 24 are uniform in the characteristics of the cone crusher 10. Although crushing is performed within the diameter range, in the case of foreign matters 22 such as wood, gypsum panel, plastic, etc. contained in the waste concrete mass 20, the crushing has a constant diameter, such as a piece of concrete 24. Elongated, flat, or tattered, easy to break.

The construction waste treatment apparatus according to the present invention has a width equal to the diameter of the concrete fragments 24 and the crushed concrete fragments 24 that maintain a constant diameter when they are crushed by the crusher 10, but are crushed in length. There is an advantage in that it is possible to sort out foreign matters 22, such as easy wood chips, pieces of plasterboard panels containing fabrics that are easily torn apart.

Cone crusher (10) used in the present invention is a device widely used conventionally in the field for treating construction waste, a machine for crushing using impact force and compression force as a crusher for secondary or tertiary crushing to be. An umbrella-shaped cone mantle head is mounted on a short vertical axis, and its eccentric motion causes the cone cave ball in the frame to be bitten down and broken down. The rotation speed is 430-580 rpm. The structure and the crushing movement are similar to those of the gyro crusher, but the cone is shorter, the feed water size is smaller, and the crushing is caused by the impact, so the structure is more complicated and the crushing cost is higher. Due to the large size of the outlet gap, it is suitable for mass production of fine aggregate having a certain size diameter by setting the range of crushing.

Conventional concrete crusher 10 is a crushed concrete piece having a diameter of the setting value without large deviation from the error range of ± 10% maximum if the size of the waste concrete crushed and discharged by the mechanical characteristics set to a certain diameter Field 24 is discharged. For example, when the setting value of the crushing range of the waste concrete is 30 mm, the concrete pieces 24 are discharged to have a diameter within 27 mm to 33 mm within an error range not exceeding ± 10% at most. However, foreign matters such as wood chips contained in the crushed waste concrete mass 20 are not crushed like concrete pieces 24 and have a width of 30 mm even if the setting value of the crushing range is 30 mm due to the characteristics of the material. It is crushed and crushed easily and is easy to be discharged.

Referring to the process of treating the construction waste using the construction waste treatment apparatus according to the present invention.

In the crusher 10, the waste concrete mass 20 is crushed to set a range to be discharged. For example, when crushing the waste concrete 20 into concrete pieces having a diameter of 30 mm, the setting value of the concrete crusher is 30 mm. The cylindrical screen 30 in which the holes 110 having a diameter corresponding to the setting value of the crushing range of the crusher 10 is formed is provided.

In the construction waste treatment site, the diameter of the crushing range of the concrete 20 of the crusher 10 is hardly changed once it is set, so that the cylindrical screen 30 according to the changed setting rarely changes. Is the reality.

First, the waste concrete 20 to be crushed is put into the crusher 10 according to the present invention. A cylinder in which the waste concrete pieces 24 and the foreign matters 22, such as wood chips, which are crushed in the range of the diameter value set in the crusher 10 are placed on the first conveyor 50 and moved to rotate in the direction of the arrow. Among the shredded construction wastes 22 and 24 which are introduced into the screen 30 and into the cylindrical screen 30, the shredded concrete pieces 22 having a predetermined diameter have a rotating cylindrical screen 30. Is discharged through a plurality of holes (110) formed in the), and move apart on the third conveyor (70). Then, the foreign materials 22, such as wood chips crushed in a long way is moved along the bone 120 between the jaw 100 and the jaw 100 is installed with a certain height in a threaded manner inside the cylindrical screen (30) 2 is moved to the conveyor (60).

The diameters of the respective holes 110 formed in the cylindrical screen 30 are formed to have a diameter of 0 to 20% longer than the diameter setting value of the concrete pieces 24 crushed and discharged by the crusher 20. More preferably, a diameter close to the 10% longer diameter.

For example, if the maximum size of the concrete pieces 24 crushed and discharged through the crusher 10 is set to 30 mm, the diameters of the respective holes 110 formed in the cylindrical screen 30 are 30 mm to 36 mm. It is preferable to manufacture in the range of 32 mm, especially since 32 mm is 10% longer diameter.

The diameter of each of the holes 110 formed in the cylindrical screen 30 is set to a diameter 10 to 20% longer than the set diameter value of the concrete pieces 24 crushed and discharged by the crusher 20 This is because the concrete pieces 24 are easily discharged through the holes 110 in the case of fabrication, while the rough foreign substances 22 such as wood chips are not discharged through the holes 110.

If the diameter of each of the holes 110 formed in the cylindrical screen 30 is 10% or less than the diameter setting value of the concrete pieces 24 crushed and discharged by the crusher 20, the crusher ( The diameter size of the shredded concrete pieces 24 actually discharged through 20 may be larger than the shredded diameter setting so that it may be difficult to be easily discharged through the hole 110.

When the diameters of the holes 110 formed in the cylindrical screen 30 are 20% or more larger than the diameter setting value of the concrete pieces 24 crushed and discharged by the crusher 20, the concrete pieces ( 24) there is a problem that can be discharged through the holes 110, as well as the foreign matter 22, such as wood chips.

2 is a perspective view showing the internal configuration of the cylindrical screen of the first embodiment according to the present invention.

Referring to Figure 2, the entire inner surface of the cylindrical screen 30 according to the present invention is formed in a spiral shape jaw 100 having a constant height as shown, the direction in which the cylindrical screen 30 rotates The foreign material 22 and the concrete pieces 24 of the wood pieces of the jagged shape are configured to move along the valley 120 between the jaw 100 and the jaw 100. In addition, a plurality of holes 110 having a diameter through which the crushed concrete pieces 24 are separated may be formed in the valley 120 between the jaw 100 and the jaw 100 formed in a spiral shape.

The diameter of each of the holes 110 formed in the valley 120 is 0 to 20% longer than the diameter of the size of the size of the waste concrete pieces 24 crushed and discharged by the compactor 10 It is preferably formed to have a diameter, more preferably having a diameter close to the 10% longer diameter.

The width of the valley 120 according to the first embodiment of the present invention of FIG. 2 is preferably made equal to the diameter of the hole 110 or no more than 20% of the length of the diameter of the hole 110. For example, if the hole is 30mm, it is preferable that the width of the valleys 120 excluding the jaw 100 is 30 mm to 36 mm.

The reason why the jaw 100 is formed in a spiral shape in the cylindrical screen 30 according to the present invention is that the crushed foreign matter 22 and concrete introduced into the cylindrical screen 30 rotated in the direction of the arrow of FIGS. 1 and 4. To adjust the feed rate and feed distance inside the cylindrical screen 30 of the pieces 24.

That is, the crushed foreign matter 22 and the concrete fragments 24 introduced into the cylindrical screen 30 must be transported and discharged to the opening opposite to the opened opening of the cylindrical screen 30. For this purpose, the tilt of the cylindrical screen is inclined. If the system adopts a method of conveying the crushed foreign matter 22 and the concrete fragments 24 by vibrating the cylindrical screen 30 or the cylindrical screen 30, the crushed foreign matter 22 and concrete fragments introduced into the cylindrical screen 30. It is impossible to adjust the feeding distance and the feeding speed per second of (24).

In addition, if a large amount of foreign matter 22 and concrete fragments 24 at once are introduced into the cylindrical screen 30, the concrete fragments 24 and the foreign matter through the cylindrical screen 30 is simply tilted or vibrated. Separation of (22) will be difficult.

The above problem can be solved through the jaw 100 formed in a spiral.

Figure 3 is a perspective view showing the internal configuration of the cylindrical screen of the second embodiment according to the present invention.

Referring to FIG. 3, the spacing of the valleys 120 between the jaws 100 and the jaws 100 within the cylindrical screen 30 of the second embodiment is within the cylindrical screen 30 according to the first embodiment of FIG. 2. Twice as much as the space | interval of the bone | tube 120 between the jaw 100 and the jaw 100 is formed.

In some cases, the waste concrete mass 20 may contain a larger amount of foreign matter 22 such as tree branches than concrete. In this case, since there is a large amount of foreign matter 22 to be sorted separately as much as the concrete pieces 24 to be discharged through the holes 110, the grooves 120 between the jaws 100 and the jaws 100 are placed in the valleys 120. All the concrete pieces 24 and the foreign substances 22 are not placed, but the foreign substances 22 are laid over the jaw 100.

In particular, the above problems are more likely to occur when the foreign matter 22 is a gypsum board or the like containing a large amount of fabric.

In addition, when the rotational speed of the cylindrical screen 30 is increased, the concrete fragments 24 and the foreign substances 22 are mounted on the jaw 100 between the jaws 100 and the jaws 120 that are formed by a thread, rather than the jaw ( 100), the possibility of lifting up inside the cylindrical screen 30 is high.

As a solution to the above problem, the cylindrical screen 30 of FIG. 3 according to the second embodiment has doubled the width of the bone 120 between the jaw 100 and the jaw 100 as shown in FIG. 3. .

In the cylindrical screen 30 of the second embodiment of FIG. 3, when the waste concrete 20 containing 20% or more of the foreign matter 22 in the waste concrete 20 before crushing is crushed by the concrete crusher 10 of FIG. More effectively than the cylindrical screen 30 of the first embodiment, the foreign matter 22 and the concrete pieces 24 were separated and sorted.

The width of the valleys 120 of the second embodiment according to the invention of FIG. 3 is equal to the length of the sum of the diameters of the two holes 110, or 20% more than the length of the sum of the diameters of the two holes 110. It is desirable that it is not exceeded. For example, if the diameter of the hole is 30mm, it is preferable that the width of the bone 120 except for the jaw 100 is 60 mm to 72 mm.

Figure 4 is a perspective view showing the internal structure of the cylindrical screen of the third embodiment according to the present invention.

Referring to FIG. 4, only two thirds of the entire length of the cylindrical screen 30 based on the portion into which the crushed foreign matter 22 and the concrete pieces 24 are introduced by the first conveyor 50 is opened. The field 110 is formed, and the third part of the direction in which the foreign matter 22 is discharged is the configuration of the cylindrical screen 30 in which the holes 10 are not formed.

Holes 110 through which concrete fragments 24 are discharged only in a portion into which the foreign substance 22 and the concrete fragments 24 crushed in the cylindrical screen 30 are introduced to lengthen the entire length of the cylindrical screen 30. Is formed to discharge the concrete fragments 24 so that holes 110 are not formed in the opposite portion of the cylindrical screen, and only the foreign matter 22 is formed in the shape of a thread while the cylindrical screen 30 rotates in the direction of the arrow. ) And is transported along the bone 120 between the jaw 100 and discharged to the second conveyor 60.

According to the construction waste treatment apparatus according to the present invention, the waste concrete mass crushed by the crusher containing foreign matter such as wood, non-combustible materials, heat-resistant materials, solidified waste synthetic resin, gypsum board panel containing the fabric as a support means It has a remarkable effect with high yield of screening with pure concrete fragments and foreign matter.

In addition, since the cylindrical screen itself can be manufactured at a low cost, even if the value of setting the diameter value of the concrete pieces discharged by the crusher is different, it is possible to set the pieces of concrete discharged by the crusher without adding much cost. Since a cylindrical screen having a hole size corresponding to the diameter value can be manufactured, there is a remarkable effect.

While preferred embodiments of the present invention have been described using specific terms, such descriptions are for illustrative purposes only and it is understood that various changes and modifications may be made therein without departing from the spirit and scope of the following claims. You must lose.
