Description

Apparatus for crushing of construction wastes}

The present invention relates to a crushing device of construction waste, more specifically, to the waste concrete aggregate crushed to 40mm or less by crushing into aggregate less than 25mm or fine aggregate less than 6mm and then compacted and rubbed The present invention relates to a crushing device for construction wastes capable of peeling cement paste while grinding and grinding concrete aggregates of weak particles having vibrations and segregation.

In general, among the construction waste, concrete structures and various buildings discharge various wastes including concrete masses including reinforcing bars mostly, earth and sand around buildings, wood generated from various waste furniture and wooden door frames installed in buildings, and the like.

As these wastes are simply disposed of, environmental pollution is generated, so that they can be recycled to prevent energy resources and reduce costs, and the waste concrete is shredded and separated into various raw materials. By doing this you are gaining recycled aggregates.

The conventional method of producing recycled aggregates using construction wastes is to crush concrete waste materials step by step several times with various crushers 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, earth and sand, and the like. Efforts have been made to separate and screen the waste concrete crushed aggregate, which is the intermediate aggregate, and reprocess it to obtain high quality aggregate.

Existing shredders used in the production method of the recycled aggregates have been presented a variety of devices, but among them are presented in the Republic of Korea Patent No. 0461084 having some of the same technical idea as the present invention.

As shown in FIG. 4, the input concrete aggregate is supplied to the state of containing moisture in the state of being injected by the water supply means of one side of the hopper, and the state is eccentric in the hollow gab at the bottom of the hopper. The input concrete aggregate is small according to the change in the gap between the inner circumferential surface of the gab and the mantle core generated by moving the mantle core through a bevel gear of a mantle core paired with a bevel gear of a counter shaft which is a horizontal axis. It is crushed into particle size.

In addition, due to the vortex action of the high-pressure air is injected from the air compressor on one side of the gab, the input concrete aggregate is guided to collide with the mantle core and the inner circumferential surface of the glove to crush more finely.

The crushing device of the patent configured as described above is absorbed by the input concrete aggregate absorbed by the water supply means on one side of the hopper, so that the dust generated as the input concrete aggregate is crushed is significantly reduced. In addition, due to the vortex action of the high-pressure air injected from the air compressor, the input concrete aggregate more strongly collides with the mantle core and is broken finely.

However, in the crushing device as described above, the cone-shaped mantle core is simply eccentrically moved inside the glove to crush the input concrete aggregates, so that the crushing into large particles is not a problem, but thick aggregates for concrete and Since cracking or segregation occurs during the crushing process of fine aggregates, there was a problem that it is difficult to obtain high-quality aggregates as circulating aggregates of coarse aggregates and fine aggregates for concrete.

Therefore, a separate crusher such as a roll crusher or a sand mill is provided, and a peeler for removing a separate cement paste is used. However, in order to obtain a high quality recycled aggregate, There was a problem in that the work of splitting the concrete aggregate into a single model was weak and the grinding and peeling of the grain edges of the crushed concrete aggregate was weak, but a lot of equipment investment cost, power loss, and a large installation place were required.

For this reason, in order to obtain high quality concrete aggregates, the concrete aggregate splitting process and the polishing process of the grain edges of the concrete aggregates were once again required. Consequently, additional processing time and processing time are required as the concrete aggregates are processed again. There was a problem that the longer work efficiency and productivity is also reduced.

The present invention has been researched and developed in order to solve the conventional closed and problems as described above, the purpose is to provide a lower mantle core in the lower portion of the upper mantle core, the lower mantle core rotates with the axis of rotation of the upper mantle core By adding vibration means, the concrete aggregates such as cracks, segregation and weak particles are broken during the crushing process, and the particles of crushed concrete aggregates are compacted and rubbed together. It is to provide a shredding device for construction waste to obtain aggregate.

The aggregate through hole 14 is eccentrically moved in the upper and lower gages 20 and 60 installed on the upper and lower surfaces of the flat base 12 so that particulates or dust of the concrete aggregate crushed by the upper and lower mantle cores 40 do not penetrate. It should be formed in consideration of the moving distance of the upper and lower mantle cores (40, 50).

The lower base 60 is mounted on the lower surface of the flat base 12 so as to receive the lower mantle core 50 at a predetermined interval in a state in which the lower mantle core 50 is rotated. The height can be adjusted via 16b). The adjustment of the lower gage 60 is because the particle size of the crushed concrete can be adjusted by adjusting the spacing with the lower mantle core 50.

The lower mantle core 50 is provided with a horizontal rotating shaft 54 which is rotationally driven by a motor, which is a second second power source 51, and a vibration weight 55 is provided on the horizontal rotating shaft 54 to impart vibration. Vibration means for adding is added.

In the drawing, reference numeral 65 is a hopper for injecting concrete aggregate to be crushed into the upper mantle core 40, and 66a and 66b are discharge chutes provided at the lower ends of the lower gage 60 and the lower mantle core 50, respectively. , 67 is a conveyor belt for transferring the concrete aggregate crushed to a predetermined particle size by the apparatus of the present invention.

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

First, since the rotary shaft 30 connected through the first power source 31 and the power transmission member 32 by applying power to the first power source 31 is rotated, the lower mantle core 50 mounted at the lower end thereof is also interlocked. Will be rotated. At this time, the rotating shaft 30 is decelerated to rotate at approximately 150 ~ 200RPM.

When power is applied to the second power source 56 on the frame 10 in a state in which the lower mantle core 50 is stably rotated, the gear is driven through an upright input shaft of the gear box 53 connected to the second power source 56. The horizontal rotation shaft 54 of the box 53 starts to rotate in rotation and rotates at 2,200 RPM.

The horizontal rotation shaft 54 of the lower mantle core 50 starts to rotate and is accelerated to the fixed weight 55a constituting the vibration weight 55 up to 200 RPM at which the rotation of the horizontal rotation shaft 54 is low. With respect to the movable weight (55b) is rotated by the rotational inertia force with the ring (55c) to be located opposite to each other, such a state, the fixed weight (55a) and the movable weight (55b) on both sides Since the position of the eccentric weight is small, the vibration of the lower mantle core 50 is weak.

At a high speed of 500 RPM or more, the horizontal rotating shaft 54 is accelerated and the movable weight 55b is rotated by the rotational inertia force with the ring 55c with respect to the fixed weight 55a constituting the vibration weight 55. It is biased to one side as one is integrated, 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 lower mantle core 50 becomes strong.

At this time, since the output shaft of the second power source 56 and the upright input shaft of the gear box 53 are concentric with the rotation shaft 30, the rotation of the lower mantle core 50 does not adversely affect the second power source ( 56 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 56 should be rotated in the same direction as the lower mantle core 50 but faster than the rotation speed of the lower mantle core 50. The reason is to rotate smoothly and stably without resistance with the lower mantle core 50.

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.

In this state, the upper and lower mantle cores 40 and 50 are operated, and the concrete aggregate crushed to 50 mm or less over several times is introduced into the upper mantle core 40 in the upper gage 20 through the hopper 65. . When the concrete aggregate to be crushed into the upper mantle core 40 in the upper gage 20 is input, the upper mantle core 40 is rotated in all directions on the plane by the eccentric cam 33 below the rotating shaft 30. In addition to the eccentric movement, an operation of lifting and lowering due to the inclined surface formed on the lower surface of the first housing 41 of the upper mantle core 40 and the upper surface of the second housing 43 below the rotating shaft 30 is performed.

Therefore, the concrete aggregate is introduced into a wide space between the upper mantle core 40 and the upper gage 20, and in this state, the upper mantle core 40 is gradually raised, and the upper mantle core 40 and the upper gave 20 Since the gap between the narrow narrow concrete aggregate is pressed between them, so that the crushed concrete aggregate is lowered when the upper mantle core 40 is lowered when a wide gap is formed.

As it is crushed as described above, the small aggregate concrete aggregate is dropped to the lower portion of the upper mantle core 40 and the upper gage 20, so the crushed falling concrete aggregate aggregate aggregate hole 14 of the flat base 12 Through the drop gage 60 and the lower mantle core 50 is dropped through.

The concrete aggregate passed between the upper mantle core 40 and the upper gage 20, the lower mantle core 50 is rotated at the same rotational speed as the rotation shaft 30, as shown in the lower mantle core 50 vibration weight In the state vibrated by the weight 55 is passed between the lower mantle core 50 and the lower gauge (60). While passing between the lower mantle core 50 and the lower gage 60, the concrete aggregate breaks the concrete aggregate such as cracks and segregation or weak particles during the crushing process in the upper mantle core 40, and the crushed concrete aggregates It grinds and rubs the edges of the grains by peeling cement paste, etc., with compacting and rubbing at high pressure.

The concrete aggregate crushed and polished to a predetermined small particle size is dropped onto the belt conveyor 67 through discharge chutes 66a and 66b formed at the lower ends of the lower gage 60 and the lower mantle core 50, and the concrete Aggregate is conveyed to the next process or stockyard by the belt conveyor (67).
