Description

The scattering dust removal apparatus for the recirculation aggregate transfer conveyor of the construction waste

The present invention relates to an apparatus for removing scattering dust and fine dust for a conveying conveyor for circulating aggregate transport of construction waste, and more particularly, to dust scattered and fine particles stuck in circulating aggregate in the process of transporting circulating aggregate of construction waste by a transport conveyor. Dust and fine dust separation and removal device for circulating aggregate transport conveyor of construction waste that separates and treats the dust and prevents the dust and fine dust from leaking to the outside and separates them separately and collects them by wet or dry methods is about

In general, various types of construction waste are discharged due to the deterioration of building structures, and since they are disposed of in a waste treatment plant, various environmental pollution problems and resource waste problems are serious.

Accordingly, there is a need to actively promote the replacement of scarce resources and cost reduction of the construction industry base while minimizing the problem of environmental pollution by enabling practical recycling through the management of the construction waste.

The construction waste refers to soil, sand, gravel, earth and sand mixed with garbage, waste materials, or a mixture of these, concrete lumps, waste wood and construction sludge, and the like. Because wastes were mixed, it was difficult to use them as useful materials.

In particular, recycled aggregate that can be reused as construction materials from the building waste was wasted more seriously due to the indifference of the government and industry.

Of course, several companies are producing recycled aggregate separately from the above-mentioned construction waste, but the quality of recycled aggregate deteriorates due to lack of technology and awareness. This results in a huge waste of resources.

That is, since the recycled aggregate of the construction waste has a lot of foreign substances such as earth dust on the surface, which lowers the quality of the recycled aggregate, it is necessary to remove fine dust, etc. attached to the surface after crushing the recycled aggregate.

To this end, a number of technologies have been disclosed to improve the quality of recycled aggregate by spraying washing water on the surface of the recycled aggregate while transporting the recycled aggregate by a conveying conveyor to wash and remove fine dust, etc. attached to the recycled aggregate. became

However, reusable recycled aggregate is obtained through a process of separation, crushing, and washing by a separation, sorting, crushing and washing device while transporting the recycled aggregate by the conveying conveyor. The amount of dust scattered around or outside the workplace increases, which not only disturbs the work environment, but also causes pollution of the surrounding air, soil, and water (environmental pollution), and the problem of deteriorating the surrounding residential environment. induced.

On the other hand, the conveyor means 10 of the present invention continuously installs at least one and continuously works while transferring the circulating aggregate. Between the conveyor means 10 located in the front and the conveyor means 10 located in the rear As in 8, by installing a screen mesh type vibrating body 70 that is inclined downward but vibrating by the vibrator 72, the circulating aggregate transported by the conveyor unit 10 in the front is transferred to the conveyor unit 10 in the rear. ) to shake off the fine dust by the vibration of the vibrating body in the process of transferring it to the unit.

At this time, the upper and lower portions of the vibrating body 70 are installed to be covered by the cover 75 , and a discharge hole 76 is formed in the lower portion of the cover, but the discharge hole is the wet or dry type dust of the above-described embodiment. It is connected to the separation means and configured to be processed together with the dust separated and collected by the conveyor means (10).

As an unexplained reference numeral, 42 denotes a discharge pipe.

Next, we will look at the operation and operation of the present invention configured as described above.

The apparatus of the present invention is to perform a process of recycling the recycled aggregate of construction waste while transferring it to the conveyor belt 15 of the conveyor means 10 at a horizontal or inclined angle.

In this process, the upper cover 20 completely surrounds the upper part of the conveyor means 10, so that the scattering dust of the circulating aggregate transported by the conveyor belt 15 and fine dust attached to the circulating aggregate are prevented from leaking to the outside. it will be done

In addition, in the process of being transported by the conveyor means (10), the scattering dust of the circulating aggregate and the fine dust attached to the circulating aggregate are peeled off, and then all are sucked and treated to separate and collect.

To explain this in more detail, the recycled aggregate of construction waste is transported and supplied by the conveyor belt 15 of the conveyor means.

At this time, since the upper cover 20 surrounds the upper part of the conveyor means 10, scattering dust, etc. falling from the circulating aggregate is prevented from leaking to the outside.

In particular, the first and second blowers 35 (35) ( 36), the fine dust is prevented from leaking to the outside through the inlet 21 and outlet 22 of the upper cover by the air blown into the upper cover from the discharge hole 37).

In addition, fine dust adhered to the circulation aggregate of construction waste is peeled off by the air blowing from the discharge hole 37 of the first and second blowers 35 and 36 to the inside of the upper cover.

As described above, the scattering dust scattered inside the upper cover 20 and the fine dust separated from the circulating aggregate are all sucked by the suction power of the suction pump 32 through the suction pipe 31 connected to the upper center of the upper cover, so they are collected separately. it will be done

As described above, scattered dust and fine dust collected by suction through the suction pipe 31 are introduced into one end (upper side of the inclined portion) of the dust discharge guider 40 installed under the conveyor means 10 .

And, the dust introduced into the dust discharge guide 40 is discharged from one side end to the discharge hole 41 of the other side end (lower side of the inclined portion) while weakening the suction power of the dust, so that the dust is gradually discharged.

In particular, left and right dust collision plates 45 and 45 ′ that are inclined downward to left and right are installed on the upper surface of the dust discharge guide 40 , and the inside of the left and right dust collision plates are vertically overlapped and spaced apart from each other. Since the part 46 is formed, the fine dust moves through the gap portion 46 through the collision that continuously collides with the left and right collision plates 45 and 45', thereby further weakening the suction power of the dust. The discharge is gradually guided to the discharge hole 41 by the inclination of the discharge guider.

At this time, the suction power of the dust discharge guider 40 is weakened and the dust gradually discharged by the inclination of the discharge guider is smoothly moved and discharged to the discharge hole 41 by the vibration of the vibrator 60 additionally installed under the dust discharge guider. that can make you do it.

In this way, the dust gradually discharged together with air through the discharge hole 41 of the dust discharge guide 40 is dropped into the water contained in the water tank 51 as shown in FIG. It is separated by precipitation and only pure air is discharged to the outside.

In addition, as in FIG. 7 , the dust gradually discharged along with the air to the lower part through the discharge hole 41 of the dust discharge guider 40 is separated and collected by the dry method by the cyclone 58, and only pure air is discharged to the outside. it might be released.

In addition, the dust discharge guide 40 is provided with a transparent opening/closing window 48, so that the operator can visually monitor the emission of fine dust or digitally monitor the fine dust at any time by a separately installed CCTV. is accumulated, the opening/closing window 48 is opened to easily perform internal cleaning and forced discharge of undischarged fine dust.

On the other hand, the conveyor means 10 is continuously installed at least one or more to work while continuously transporting the circulating aggregate. It will work while continuously moving the recycled aggregate like in the above.

At this time, the vibrating body 70 transfers the circulating aggregate by vibration by the vibrator 72 at the bottom and shakes off the fine dust of the circulating aggregate to the lower part of the screen mesh type vibrating body.

As such, the fine dust falling from the vibrating body 70 is guided downward by the cover 75 covering the upper and lower parts of the vibrating body and discharged through the lower discharge hole 76. ) is to be collected and processed by a wet or dry method in the tank 51 or cyclone 58 together with the dust separated and collected from the recycled aggregate transferred by the
