Description

Separation apparatus for reproducing used-aggregate}

The present invention relates to a waste aggregate recycling apparatus, and in detail, a device for separating foreign substances such as papers contained in the waste aggregate in the process of recycling the waste aggregate, mainly the waste aggregate generated in construction for reconstruction or expansion of buildings. Technology for the purpose of recycling.

In general, the waste aggregate discussed in the present design refers to the aggregate of concrete cured to form a wall or skeleton of a building. When the building is formed, various kinds of interior materials such as paper, wood, and gypsum are used in the cured concrete wall so that the interior materials that cannot be recycled are included. The waste aggregate is aggregate after use because the composition is mineral. The nature of itself is not deformed, the separation of the above foreign matter will be possible to recycle the waste aggregate.

Conventionally, in order to separate such foreign matter from the waste aggregate, relying costs are mostly consumed as labor costs because relying on manual labor using manpower has a problem of very low regeneration efficiency. Therefore, the waste aggregate was disposed of as waste without being recycled, or part of it was disposed of in land reclamation projects.

Most of the aggregates for building are minerals of gravel and sand, and in recent years, it has become a major factor in the destruction of the natural environment due to indiscriminate harvesting in nature.

Therefore, the recycling of waste aggregate is urgently required, and various waste aggregate recycling apparatuses have been developed.

The conventional recycling apparatus is generally recycled through the operation of separating the fine aggregate and the separation of foreign matter by manpower to collect and recycle the waste aggregate, as described in the introduction is difficult to separate the foreign matter and its efficiency is very high Due to the low problem, a large amount of regeneration is difficult and the separation of foreign matter is not perfect, there is a problem of low quality of the waste aggregate. In addition, a separator for separating foreign matters has been developed by a mechanical device. The principle is a separation device that separates light debris by blowing away heavy aggregates.

However, the conventional separation device has a problem of degrading the quality of recycled aggregates because the foreign matters of very light paper are easily separated, but the wood chips having a relatively long length are not separated.

The present invention aims to improve the quality of recycled aggregates by completely separating foreign substances having a length as devised to solve the conventional problems as described above.

The present invention for achieving the above object is made of a conventional grinding means for pulverizing the waste aggregate to a certain size and a separation means for easily separating foreign matters such as papers and wood chips lighter than the aggregate in detail with reference to the accompanying drawings. Explain.

Figure 1 is a representation of the overall configuration of the subject innovation and Figures 2 to 4 is a detailed view of the main part of the subject innovation, finely crushed by a pulverizing device (1) for collecting the waste aggregate 100 and crushing to a predetermined size It is made of pulverized aggregate 101 and transferred to the smoothing device 11 using the crushed aggregate conveyor (4), and the smoothing device 11 freely falls the pulverized aggregate 101 to the separating device 10, pulverized aggregate 101 From this, a series of work steps are performed to separate and regenerate the foreign matter 300 such as paper 102 and wood chips 103 and the recycled aggregate 200.

The grinding device 1 is composed of a waste aggregate hopper (2) and a grinder (3),

The smoothing device 11 is provided with a vibrator 16 on the side of the vibration smoothing plate 15 supported by the free flow spring 17a on the upper side of the base 17, and at the end of the vibration smoothing plate 15. A plurality of wood carving guide pins 15a are laid.

In addition, the separating device 10 is composed of a blower 19 having a cylindrical separation drum 12, a rotating device 10a, and a blower 18 having air blocking plates 13 attached to both ends thereof.

The foreign matter storage tank 30, the storage tank conveyor 20 and the aggregate storage tank 40 are installed at the lower side of the separation device 10 to separate the foreign matter 300 and the recycled aggregate 200 separated by the separation device 10, respectively. It is configured to store in another storage.

The operation and effects of the present invention configured as described above will be described in more detail.

First, in order to regenerate the waste aggregate generated as a by-product of the reconstruction or extension of the building, only the aggregates are collected by separating various metal materials and wood.

Various foreign matters are attached to the collected waste aggregate 100, and the aggregate mainly used as a wall of the building is attached with a part of interior materials such as paper, paint, plaster, and the like.

Therefore, before entering the regeneration operation, a relatively large volume of foreign material such as wood chips, rebars, etc. may be performed in the first step of separating the lumps in the wild and breaking the large aggregates of waste aggregates into smaller pieces.

Full-scale regeneration of the waste aggregate 100 subjected to the primary separation process is performed by the pulverizer 3 operated at the lower side when the waste aggregate 100 is put into the waste aggregate hopper 2 as shown in FIG. 2. Grinded finely into a crushed aggregate 101 of a constant size.

At this time, the crushed waste aggregate 100 is pulverized while the crushed aggregate 101 and paper 102, the wood chips 103, etc. are separated, and the paints attached to the surface are also separated into powder.

The paper 102 is mostly in the form of small pieces, and the wood chips 103 are separated into small pieces that are broken or split into branches having a length in a grain direction.

The pulverized aggregate 101 pulverized as described above falls to the crushed aggregate conveyor 4 being operated and is transferred to the smoothing device 11 as shown in FIG. 3.

The smoothing device 11 is supported on a free flow spring 17a fixed to an upper side of the base 17 so as to be freely flowable, and the vibration smoothing plate 15 which is slightly inclined toward the separating device 10. A plurality of vibrators 16 are formed on the upper side, and a plurality of vibrators 16 are attached to the side, and the vibrators 16 are conventional vibrators 16 in which a motor for rotating an eccentric weight is built.

Therefore, when the vibrator 16 is operating, the upper vibration smoothing plate 15 vibrates finely.

When the pulverized aggregate 101 and the foreign matter 300 transferred from the pulverized aggregate conveyor 4 are put on the upper side of the vibration smoothing plate 15, the pulverized aggregate 101 is unfolded evenly by vibrating and pulverized aggregate 101. ) And foreign matters 300 to work so as not to get tangled with each other.

The crushed aggregate 101 and the foreign matter 300 is evenly spread as described above is gradually moved in the inclined direction in the vibrating vibration smoothing plate 15, at this time, installed at the end of the vibration smoothing plate 15 as shown in FIG. After contacting and aligning the twig guide pin 15a at a predetermined interval, the free fall to the separation device 10 installed on the lower side.

At this time, the action of the branch guide pin (15a) has a function to put the wood chip 103 moving in the horizontal direction in the vertical direction, the purpose of which is the surface when the wood block 103 falls in the horizontal direction This is because it is a small and weighted object so as not to be separated from the separation device 10 so as to span the upper portion of the separation drum 12 which is rotating in the foreign matter storage tank 30.

The separation device 10 allows the separation drum 12 to rotate the rotation device 10a in the direction of the foreign matter storage tank 30 and the blower 19 installed below the end of the vibration smoothing plate 15 is the separation drum 12. It is configured to inject the compressed air generated by the blower 18 in the lateral direction of the air is injected into the foreign matter storage tank 30 riding on the surface of the separation drum (12).

Therefore, the crushed aggregate 101 and the foreign matter 300 falling from the vibration smoothing plate 15 passes between the blower 19 and the separating drum 12 of the separation device 10, wherein the heavy crushed aggregate 101 ) Is continuously blown to the lower side without blowing to the blowing air of the blower 19 and the foreign matter 300 of the light paper 102 and the small piece of wood 103 is blown into the blowing air and falls into the foreign matter storage tank (30).

The pulverized aggregate 101 passing through the separation device 10 acting as described above is separated from the foreign matter 300 to become a recycled aggregate 200 and dropped to the storage tank conveyor 20 and then transferred to the aggregate storage tank 40. It can be recycled.

The present invention, which works as described above, is a very advanced design that has the effect of effectively separating the wood chips contained in the waste aggregate into the regeneration device. Compared with the recycled aggregates, it is designed to recycle recycled aggregates of very good quality.
