Description

[0001] Apparatus for cleaning aggregate by wind power [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a technique for cleaning aggregates, and more particularly, to an aggregate wind power cleaning apparatus for separating foreign matters or stones attached to aggregates using wind power.

The materials used for civil engineering and construction work such as lecturers and marine construction could be indiscriminately harvested due to the revitalization of the construction industry. However, in recent years, the amount of harvest is limited in order to limit damage and destruction of ecosystem.

Recently, in order to solve the scarcity of soil and aggregate, recycled soil (recycling) and aggregate are being produced by producing artificial soil from mountainous areas or using waste concrete through construction waste.

The aggregate produced is usually produced by crushing, crushing, and discharging the foreign matter and then dividing it into soil and aggregate.

On the other hand, when producing aggregates from rocks, etc., the aggregate is finally washed using a hydraulic washer to obtain pure and high quality aggregates.

However, since the aggregate cleaning method using water requires a large amount of water consumption as well as a wastewater treatment facility due to the discharge of polluted water, there is a problem that the cleaning cost is increased, and in the winter season, the aggregate freezes and the aggregate production is disrupted In addition, there is also a problem that after the aggregate cleaning, moisture is present in the aggregate for a long time and the aggregate shipment time is delayed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The aggregate wind power cleaning apparatus according to the present invention can include a first wind power separation tank 10, a blowing fan F, and a second wind power separation tank 20.

1 to 5, the first wind power separation tank 10 is provided with a stepped step portion 13 at a portion where the aggregate fed from the hopper 11 falls, (13).

For example, a hopper 11 is installed at an upper end of the first wind power separation tank 10, aggregates are introduced into the first wind power separation tank 10 from the hopper 11, A step portion 13 formed by connecting a plurality of vertical surfaces and horizontal surfaces at a lower position can be formed. A lower portion of the first wind power separation tank 10 is opened and a conveyor belt is installed below the opened first wind power separation tank 10 so that the aggregate discharged from the first wind power separation tank 10 You can move to the desired point.

The blowing fan F blows air to the through holes 15 formed on the vertical surface of the step 13 to scatter fine aggregate and fine particles smaller than a predetermined size into the inner space of the first wind power separation tank 10.

At this time, driving means such as a motor may be installed for driving the blowing fan F.

The second wind power separation tank 20 is configured such that the fine aggregate and the fine particles scattered from the first wind power separation tank 10 are introduced and the inflowing fine aggregate and the fine powder are dropped on the inner surface.

For example, when the fine aggregate and the fine powder flow into the second wind power separation tank 20 from the first wind power separation tank 10, the fine aggregate and the fine powder collide with the inner surface of the second wind power separation tank 20, Can flow down on the inner surface of the tank (20). At this time, the lower end of the second wind power separation tank 20 is opened, and the second wind separation tank 20, in which the fine aggregate flowing down the inner surface of the second wind power separation tank 20 and the fine particles are opened, As shown in FIG.

According to the present invention, by removing fine aggregate and fine particles adhering to the aggregate by blowing air on the aggregate, the cost of the aggregate cleaning can be reduced as compared with the existing aggregate cleaning method in which the water washing is performed.

Particularly, in the present invention, the aggregate falling from the hopper 11 does not directly fall to the discharge port at the lower end but falls over the stepped portion 13 formed in a stepped shape and falls down along the stepped portion 13, So that the efficiency of removing fine aggregate and fine particles attached to the aggregate is further enhanced and the aggregate does not directly fall on the inner surface of the first wind power separation tank 10 and the damage of the first wind power separation tank 10 Thereby preventing danger.

2 and 3, in the present invention, a blowing space 13a may be formed in the back surface of the step portion 13 so as to communicate with the through hole 15. [

One end of the blowing pipe 19 may be connected to the blowing fan F and the other end of the blowing pipe 19 may be connected to the blowing space 13a.

That is, the wind generated from the blowing fan F is blown into the air blowing space 13a by the blowing pipe 19, and the air blown into the air blowing space 13a passes through the through hole 15 formed in the step 13, To the inner space of the first wind power separation tank (10). As a result, the fine aggregate adhering to the aggregate can be removed by dropping the fine aggregate.

In addition, the through holes 15 may be formed in at least two positions along the step portion 13. [

For example, in the case where the through holes 15 are formed at the upper and lower portions, the through holes 15 formed at the upper portion serve to primarily air shower the aggregate introduced through the hopper 11 and to spread a large amount of aggregate widely and evenly can do.

In the through hole 15 formed in the lower part, the fine aggregate, fine powder, and sand or the like smaller than the standard can be scattered together with the function of washing the aggregate spreading from the upper part again.

At this time, the cross-sectional area of the blowing space 13a connected to the through-hole 15 gradually decreases toward the through-hole 15.

That is, the wind which is discharged through the through hole 15 is formed in the same shape as the aspiration nozzle, and the wind is sprayed, so that more powerful wind is blown through the through hole 15 to improve scattering efficiency of the aggregate.

1 to 3, the present invention is characterized in that the first wind power separation tank 10 and the second wind power separation tank 20 are communicably connected by a connection portion 17, Can be formed at a portion facing the through hole (15).

That is, the through hole 15 is formed to face the connecting portion 17, so that the fine aggregate and the fine particles scattered along with the wind discharged to the front of the through hole 15 pass through the connecting portion 17 to the second wind separation tank 20, So that it can be effectively introduced into the inside.

4, a partition 21 may be provided in the second wind power separation tank 20 so as to face the connection portion 17. The partition 21 may be formed in a cylindrical shape, May be fixed to the upper end of the second wind power separation tank (20).

That is, the fine aggregate and the fine particles scattered in the first wind power separation tank 10 are introduced into the second wind power separation tank 20 through the connection portion 17. At this time, some fine aggregate is separated from the outer surface of the partition 21 And the remaining fine aggregate aggregates rotate along the outer surface of the partition 21 due to the swirling phenomenon so that they can collide with the outer surface of the partition 21 and fall down. Therefore, the fine aggregate flowing into the second wind power separation tank 20 can be filtered out.

4 and 5, the lower end of the partition 21 is opened to connect the upper end of the second wind power separation tank 20 to the inner space of the partition 21, The upper end of the partition 20 and the blowing fan F are connected by the circulation pipe 29 so that the air inside the partition 21 can be circulated and introduced into the blowing fan F. [

At this time, since the filter 23 is replaceably installed at the end of the circulation pipe 29, the air flowing into the circulation pipe 29 can be passed and the fine particles in the air can be filtered.

That is, the fine aggregate having a relatively heavy mass falls down to the lower portion while bombarding the partition 21, but the relatively light fine powder or dust is scattered in the second wind power separation tank 20 through the circulation pipe 29 And is introduced into the partition 21 by the suction force. Accordingly, the fine particles and dust mixed in the air are filtered through the filter 23, and only the purified air filtered through the filter 23 is circulated and introduced into the blowing fan F through the circulation pipe 29, Can be recycled to clean the aggregate.

The filter 23 may be coupled to the end of the circulation pipe 29 connected to the upper end of the second wind power separation tank 20 and the filter 23 may be provided with a vibration device 25, ) Can drop the filtered fine particles.

That is, since the vibrating device 25 is installed in the filter 23, fine particles and dust, etc., filtered through the filter 23 are separated from the filter 23, so that the time for replacing the filter 23 can be reduced.

In addition, the discharge door 27 may be provided at the lower end of the second wind power separation tank 20, and the discharge door 27 may be periodically opened.

For example, the discharge door 27 can be periodically opened or closed under the control of the control unit by connecting a drive means such as a motor to the discharge door 27 and providing a control portion capable of controlling the drive means .

That is, by providing the discharge door 27 that can be repeatedly opened or closed depending on a predetermined time or a certain amount of powder accumulation, it is possible to minimize the risk of dust generation that may occur in powder discharge from the second wind power separation tank 20 .

As described above, according to the present invention, by removing fine aggregate and fine particles adhering to an aggregate by blowing an aggregate material, the cost to be used for aggregate cleaning is reduced as compared with the existing aggregate cleaning method in which the aggregate material is washed with water, It is possible to produce aggregate irrespective of season, and it is possible to ship the aggregate immediately after the aggregate washing.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the specific embodiments set forth herein; rather, .
