The blowing pipe 41 is piped so as not to be interfered with the surrounding obstacle.

An opening control valve 42 may be provided for controlling the amount of wind blown into the case 10 through the blowing pipe 41 and the wind speed.

The opening degree control valve 42 is, for example, a plate member which is installed in the blowing pipe 41 so as to be able to project and retract into the blowing pipe 41 to reduce the opening thereof and, on the contrary, The opening degree control valve 42 may be configured in various forms such as a butterfly valve type.

The vibrating screen 50 is a conventional vibrating screen in which a screen 51 is installed through a support stand or the like and separates and separates fine particles smaller in size than the sorting ball downward and induces a foreign substance larger in size than the sorting ball to the discharge end To produce foreign matter free from fine particles.

The vibrating screen 50 is applied with a cover 52 to prevent scattering of the foreign matter in the process of sorting out the foreign matter. Accordingly, the vibrating screen 50 has a portion corresponding to the foreign matter discharge port 13, And the other part is closed.

Here, the portion corresponding to the foreign matter discharge port 13 and the portion for discharging the foreign matter are arranged opposite to each other, and the wind flows into the portion corresponding to the foreign matter discharge port 13, flows along the screen 51, And the diffusion barrier film 53 is formed at the discharge end of the vibration screen 50 in order to prevent the discharge. The anti-scattering film 53 is disposed on the upper portion of the screen 51 so as to prevent discharge of wind and fine particles while discharging foreign matter.

In addition, the screening induction film 54 is applied to the upper portion of the screen 51 in the direction of closing the airflow so as to introduce the foreign matter and the fine particles supplied to the vibration screen 50 to the screen 51.

The screening induction film 54 is made of one or more rubber plates or the like.

Therefore, the foreign matter and the fine particles are struck on the screen 51 and dropped on the lower screen 51, thereby increasing the sorting efficiency of the fine particles.

In addition, a sprinkling facility may be provided to increase the sorting efficiency of the differential.

The water spraying facility is for spraying water toward the screen 51 from above the screen 51 of the vibration screen 50 to remove fine particles remaining in the foreign substance and one or more spray pipes 55 are installed inside the vibration screen 50 A water tank, a pump, and the like are provided to supply water to the spray pipe 55.

The foreign matter can be concentratedly discharged between the case 10 and the vibration screen 50 while the foreign substance is supplied to the vibration screen 50 inside the case 10, A bottom portion 17 may be included.

Also, since the wind flows on the inclination of the second drop plate 30 and the vibration screen 50 is opposite to the second drop plate 30, a vortex phenomenon can occur and a curved And the wind is guided to the vibrating screen 50. The vibrating screen 50 has a curved surface, The ceiling portion 18 may be straight.

It is preferable that the bottom portion 17 and the curved top portion 18 of the airless structure are formed in the form of a duct together with the right and left side walls.

The bottom portion 17 and the ceiling portion 18 of the vacuum cleaner may be integrally formed in the case 10 or the vibration screen 50 in the form of a duct or may be constituted by a separate duct to form the case 10 and the vibration screen 50 As shown in Fig.

Further, although not shown in the drawing, a circulation pipe may be included to supply the wind supplied to the vibration screen 50 back to the case 10 without discharging the air to the atmosphere.

The circulation pipe is connected to the inside of the vibration screen 50 and the blower 40 or the blower pipe on both sides thereof, that is, the blower 40, the blower pipe 41, the case 10, the vibration screen 50, The circulation path of the wind by the pipe-blower 40 (or the blowing pipe 41) is formed.

The aggregate in which the foreign matter is selected through the present invention is conveyed to the next process, for example, through the product conveyor 60, and the foreign matter is stored in, for example, a box (all collecting foreign matters as an armor box or the like) May be stored in a box (referring to all collecting the differential as an armo-box or the like) or conveyed to the product conveyor 60.

The differential conveying means 70 is a conveyor for conveying the fine particles passing through the sorting hole of the screen 51 to the product conveyor 60 and conveying the fine particles together with the aggregate through the product conveyor 60. That is, the differential conveying means 70 is applied only when the fine powder and the aggregate can be supplied together. The chute 71 can be configured so that the differential is not scattered to the outside together with the differential conveying means 70.

The method for separating foreign materials from aggregate using the foot, wind and vibration according to the present invention is as follows.

1. Input of mixture of aggregate and foreign matter.

For example, the present invention is installed at a stage before commercialization in the processing of construction waste or quarry aggregate, and is supplied with a mixture of aggregate and foreign matter by a screen, a conveyor belt, a crane, a worker or the like.

The mixture of the aggregate and the foreign matter is injected into the case 10 through the mixture inlet 11 and drops to the first drop plate 20. [

2. Foreign matter selection.

The aggregate and the foreign matter are impacted when they fall on the first drop plate 20, and foreign matter falls off the aggregate primarily by this impact.

The aggregate and the foreign matter descend along the first drop plate 20 by the inclination of the first drop plate 20 and drop onto the second drop plate 30 at the drop end.

In this process, when the dispersion stick 21 is applied, the aggregate and the foreign matter pass through the dispersion rod 21, and the aggregate falls into the second drop plate 30 through the space between the dispersion bars 21, (21).

The aggregate falling from the first drop plate (20) collides with the second drop plate (30). At this time, the foreign matter not separated from the first drop plate (20) is separated.

The foreign matter is separated from the surface of the second drop plate 30 by the adhesion preventing jig 31 without adhering to the surface of the second drop plate 30, The foreign matter is scattered to the foreign matter discharge port 13 while flowing. Therefore, it is possible to efficiently separate and discharge the foreign matter to be attached to the surface of the second drop plate 30 through its own viscosity, such as a rubber plate, to the outside of the case 10.

The wind blown into the case 10 through the blowing pipe 41 is blown by the first falling plate 20 and the second falling plate 20 through the air blowing pipe 41. [ Passes through the gap between the drop plates (30), and flows toward the foreign matter discharge port (13) by the inclination of the second drop plate (30). In this process, the aggregate which is not influenced by the wind power falls to the aggregate discharge port 12 at the bottom and is discharged to the outside of the case 10. The foreign matter flows to the foreign matter discharge port 13 by the wind- And is externally supplied to the discharge and vibration screen 50.

As a result, the foreign material produces the selected aggregate.

3. Differential sorting.

The foreign matter supplied to the vibration screen 50 includes a fine powder and the foreign matter and the fine powder flow toward the discharge end of the vibration screen 50 between the screen 51 and the cover 52 by the blowing force.

The wind is guided along the screening inducing film 54 together with the foreign matter and the fine powder to the screen 51 at the lower side and the differential and small winds of the size smaller than the screening hole of the screen 51 pass through the screening ball And is selected from foreign substances.

The fine particles selected by the screen 51 of the vibration screen 50 are conveyed to the product conveyor 60 through the differential conveying means 70 and conveyed together with the aggregate.

In addition, most of the fine particles contained in the foreign substance are removed by shaking off the foreign substance dropped on the screen 51 by the vibration screen 50 to remove the fine particles.

The foreign matter is discharged to the outside through the discharge end of the vibration screen (50).

Through the above process, aggregate, foreign matter and fine particles are selected.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood, however, that the invention is not to be limited to the specific forms thereof, which are to be considered as being limited to the specific embodiments, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. .
