Polishing Apparatus for recycling aggregate of construction wastes

The present invention relates to a grinding device for construction waste for recycled aggregate, and more specifically, when the waste concrete aggregate crushed to 20 ~ 30mm or less is input to the concrete aggregate having a crack by rubbing the mantle core rubbed. The present invention relates to a grinding device for construction wastes for recycled aggregates, which can be peeled off as well as crushed while being pressed, to separate cement paste.

In general, concrete structures or various buildings among the construction wastes are mainly made of concrete masses including reinforcing bars and earth and sand around the building. The recycling process is performed by crushing the concrete masses and soils and separating them into various raw materials. By doing this, recycled aggregate is obtained.

A typical method of producing recycled recycle aggregate using construction waste is to crush concrete waste materials in several stages with various crushers several times, and to crush them to a predetermined particle size. Intermediate aggregates (including fine aggregates of 6 mm or less) are obtained by separating and removing synthetic resins and earth and sand, and then, the fine aggregates are separated and sorted and reprocessed.

Reference numeral 60, which is not described in the drawings, is a hopper for injecting concrete aggregate to be crushed by the mantle core 30, and 61a and 61b are discharge chutes provided at the lower ends of the gab 20 and the mantle core 30, respectively. Is a conveyor belt for transferring the concrete aggregate crushed by the apparatus of the present invention.

Using the grinding device of the construction waste for the recycled aggregate according to the present invention configured as described above will be described in detail the grinding process of the concrete aggregate.

First, by applying power to the first power source 44, the hollow rotary shaft 40 connected through the first power source 44, the power transmission member 45 and the pulley 43 is rotated, but the hollow rotary shaft 40 at this time ) Is decelerated to be rotated to approximately 200 ~ 250RPM, the mantle core 30 mounted on the lower end of the hollow rotating shaft 40 is also interlocked rotation. At this time, since the inclined surface is formed on the upper surface of the first bearing 41 and the lower surface of the pulley 43, the mantle core 30 is lifted once by one rotation of the mantle core 30. .

When the mantle core 30 is stably rotated and the power is applied to the second power source 50 on the top of the frame 10, the connecting rotary shaft 40 and the gear box 53 connected to the second power source 50 are provided. Start to rotate the upright input shaft of the gearbox 53, the horizontal rotation shaft 54 of the gearbox 53 through the upright input shaft of the gearbox starts to rotate in rotation to 2,200RPM.

The horizontal rotation shaft 54 in the gearbox 53 installed in the middle of the mantle core 30 starts to rotate and acceleration is achieved, but the vibration weight weight 55 until the rotation of the horizontal rotation shaft 54 is 500 RPM at low speed. The movable weight 55b is rotated as shown in FIG. 8 due to the rotational inertia force with the ring 55c relative to the fixed weight 55a constituting the fixed weight 55a, and is positioned at opposite positions opposite to each other. Since the weight 55a and the movable weight 55b are located at both sides, the eccentric weight difference is small, so that the vibration of the mantle core 30 is weak.

At a high speed of 500 RPM or more, the horizontal rotating shaft 54 is accelerated, and the movable weight 55b is shown in FIG. 9 due to the rotational inertia force with the ring 55c with respect to the fixed weight 55a constituting the oscillating weight 55. As it is rotated and moved as one is integrated into one side, the state is biased to one side, and in this state, the fixed weight 55a and the movable weight 55b are concentrated on one side, so that the eccentric weight difference is large, the vibration of the mantle core 30 is strongly do.

At this time, since the output shaft of the second power source 50 and the upright input shaft of the gear box 53 are concentric with the hollow rotation shaft 40, the rotation of the mantle core 30 is not adversely affected, and thus the second power source ( 50 and the horizontal rotating shaft 54 from which power is transmitted can be freely rotated. In addition, the output shaft of the second power source 50 should be rotated in the same direction as the mantle core 30, but faster than the rotation speed of the mantle core (30). The reason for this is to rotate smoothly and stably without resistance with the mantle core 30.

As the rotation of the horizontal rotating shaft 54 is increased or decreased, the movable weight 55b moves and rotates with respect to the fixed weight 55a constituting the oscillating weight 55 of the horizontal rotating shaft 54. The device can prevent excessive vibration and smooth operation.

As such, the aggregate aggregate crushed to 20 to 30 mm or less, including the fine aggregate of 6 mm or less, in the state where the mantle core 30 is operated, is inside the aggregate departure preventing member 21 of the upper part of the gage 20 through the hopper 60. The upper part of the protective cover 32, which is the upper end of the mantle core 30, is injected.

The concrete aggregate thus introduced is the mantle core 30 and the mantle core 30 in a state in which the mantle core 30 is vibrated by the vibration weight 55 while the mantle core 30 is rotated and lifted at the same rotational speed as the hollow rotating shaft 40. Passes between the gave (20).

In other words, the mantle core 30 is raised and lowered once each time the mantle core 30 is rotated by the inclined surface formed on the upper surface of the first bearing 41 and the lower surface of the pulley 43. Therefore, the concrete aggregate is introduced into a wide space between the mantle core 30 and the gab 20, the concrete aggregate introduced into such a large space as the mantle core 30 is raised and lowered by its own weight, the mantle Since the gap between the core 30 and the gab 20 is narrowed, the concrete aggregates such as cracks and segregation or weak particles are broken during the crushing process of the concrete aggregates, and the crushed concrete aggregates are rubbed together as they are compacted.

In particular, the concrete aggregate passing between the mantle core 30 and the gab 20 is compacted while pressing and acting to push the spiral projection 31 of the mantle core 30 to the lower portion of the gab 20, Since concrete aggregates serve to effectively rub the crushed concrete aggregates while being hung and rotated by the circular pins 22, the cement paste is peeled while grinding the grain edges roundly.

The concrete aggregate crushed and polished in such a small particle falls down when the mantle core 30 is raised by the inclined surfaces of the upper and lower surfaces where the first housing 41 and the pulley 43 are in contact with each other. Dropped to the belt conveyor 62 through the discharge chute (61a, 61b) formed at the lower end of the 20 and the mantle core 30, the concrete aggregate is transferred to the next process or storage site by the belt conveyor (62). .
