Description

Building waste automatic treatment apparatus {Building waste automatic treatment apparatus}

The present invention relates to an automatic construction waste disposal device, and more specifically, to primarily crush construction waste input through a hopper through a jaw crusher, to sort out the primarily crushed construction waste through a magnetic separator and a trommel, and convert it into a cone. It relates to an automatic construction waste disposal device that is secondarily crushed through a crusher.

Construction waste refers to soil or sand mixed with waste materials, sand, gravel, soil, or a mixture of these, concrete lumps, waste wood, asphalt concrete lumps, and construction sludge. One of the main characteristics of construction waste is that it is harmless to the human body as it is mostly composed of inorganic materials, and that various types of waste are discharged in a mixed state.

It is said that the treatment is complicated and difficult, and this is the reason for the government and industry's indifference to the treatment of construction waste, which can be used as a useful material.

This indifference accompanied the waste of valuable resources and caused the deterioration of the quality of the recycled aggregate, which was being made, so that the utilization of the recycled aggregate was mostly used as a substitute for earth sand, such as filling, covering, and reclamation.

Therefore, it is necessary to actively promote minimization of environmental pollution, substitution of scarce resources, and cost reduction based on the construction industry by enabling practical recycling through the management of these wastes.

To this end, the 『Act on the Promotion of Saving and Recycling of Resources』 was recently enacted in Korea, and recycling of construction waste began to become mandatory.

3 is a view showing the configuration of a swing jaw 220 according to an embodiment of the present invention, and FIG. 4 is a view showing the configuration and operating state of a fixed jaw 230 according to an embodiment of the present invention. .

3 and 4, the swing jaw 220 and the fixed jaw 230 according to an embodiment of the present invention include a plurality of crushing protrusions for uniform crushing of input construction waste, In detail, the swing jaw 220 forms a lateral row on the upper surface of the surface facing the fixed jaw 230 of the swing jaw 220, and a plurality of swing jaws mounted in the downward longitudinal direction of the swing jaw 220. It includes a crushing protruding bar 221, which can be worn in the process of crushing construction waste, so it can be implemented to be detachable. Similarly, the fixed jaw 230 may be implemented such that a plurality of fixed jaw crushing protruding bars 231 are detachably formed in rows in the transverse direction on a surface of the fixed jaw 230 facing the swing jaw 220 . Each of the plurality of fixed jaw crushing protruding bars 231 protrudes low at the upper position of the fixed jaw 230 and protrudes high at the lower position, so that the upper surface has an inclination facing upward to be repeatedly provided. can In this way, when the plurality of crushing protrusions included in the swing jaw 220 and the fixed jaw 230 are adjacent to each other, the input construction waste is crushed by the downward pushing force and the pressure of the plurality of crushing protrusions pressing each other. It can be.

The plurality of fixed jaw breaking protruding bars 231 according to an embodiment of the present invention includes a first fixed jaw breaking protruding bar 232 and a second fixed jaw breaking protruding bar 233 having different areas. At this time, the second fixed jaw crushing protrusion bar 233 is located lower than the first fixed jaw crushing protrusion bar 232, and one end of the second fixed jaw crushing protrusion bar 233 is crushed by the jaw crusher 200 It includes a discharge gap through which the constructed construction waste is discharged.

The expansion and contraction rod is for preventing damage to the shielding member by absorbing the amount of impact applied to the shielding member when some of the construction waste crushed by the shielding member collides. For example, referring to FIG. When construction wastes collide, they move upward of the fixing jaw 230 to absorb the impact and at the same time guide the collided construction wastes to be put into the interior again.

The first protrusion further includes an elastic rotating shaft and a locking portion in order to more absorb the impact of the shielding member. The elastic rotational shaft is formed to be fixed by penetrating the end of the shielding member, and the shielding member can secondarily absorb an impact by an elastic body included in the rotational shaft by rotating based on the elastic rotational shaft. However, in the case where the shielding member is provided to be rotatable in this way, when some of the construction wastes crushed beyond the elastic force provided by the elastic rotation shaft collide with each other, if the shielding member rotates more than the standard value, it will no longer function as a shielding member. Since the rotation of the shield member cannot proceed beyond a certain angle, a locking portion may be further included. Through such a locking portion, the original role of preventing construction waste from being discharged to the outside of the shielding member can be continued. On the other hand, the shielding member according to one embodiment of the present invention has been described in the shape of an “a”, but this is only premised for convenience of explanation, and proceeds to prevent some of the construction waste from being discharged in the direction of being discharged to the outside. It can include all of the various forms such as “ㅡ” and “^” that allow the direction to be changed.

The first protrusion may further include a screw portion detachable from the plurality of fixed jaw breaking protruding bars 231 or the plurality of swing jaw breaking protruding bars 221 at the lower end. Through this, it is possible to easily replace the worn first protrusion among the plurality of first protrusions. In addition, the first protrusion may be detached not only from the first fixed jaw-breaking protruding bar 232 but also from the second fixed jaw-breaking protruding bar 233.

The rotational part adjusts the rotational angle of the rotation shaft 234 and the second fixed jaw crushing protrusion bar 233, which are rotatably fixed at a point on the upper side of the second fixed jaw crushing protrusion bar 233, so that construction waste is removed from the jaw crusher. It includes a gap adjustment unit 235 for adjusting the gap between the discharge gaps discharged from the first conveyor 400. The gap control unit 235 may be provided so that the second fixed jaw breaking protruding bar 233 rotates with respect to the rotation shaft 234 by a driving motor or a hydraulic device 213 .

The pressure sensor can detect the pressure when discharged from the discharge gap, and in the automatic construction waste treatment device according to an embodiment of the present invention, when the pressure sensor detects a pressure equal to or greater than a predetermined first level, the gap adjusting unit 235 Adjusts the interval of the discharge gap so that the first rotation angle of the plurality of rotation angles has a second rotation angle having a larger angle than the first rotation angle, and if the pressure sensor detects a pressure of a predetermined second size or less, the interval adjustment The unit 235 may be implemented to adjust the distance between the discharge gaps to have a third rotation angle having a smaller angle than the first rotation angle among the plurality of rotation angles. For example, if the pressure sensed by the pressure sensor is equal to or greater than a preset first level, it may be determined that the swing jaw 220 and the fixed jaw 230 inside the jaw crusher 200 have a load. In this case, the injected construction waste may be harder than before, or the injected amount is large, so that the swing jaw 220 and the fixed jaw 230 are discharged with a second rotation angle to reduce the load. It is to adjust the gap between the discharge gaps. On the other hand, when a pressure equal to or less than the preset second size is sensed, the gap control unit 235 can crush the swing jaw 220 and the fixed jaw 230 inside the jaw crusher 200 more strongly, or It is determined that the construction waste is weak compared to the prior art, and in order to make the pressure generated in the swing jaw 220 and the fixed jaw 230 stronger, the distance between the discharge gaps discharged to have a third rotation angle is adjusted.
