The blow-by screening part 100 includes a ballistic nozzle 120 arranged at a lower portion through which the sorting object flows through the transfer unit 10 and air is blown in one direction through a blow- May be included.

Each of the above-described configurations will be described in detail below.

The transfer unit 10 can be realized as a conveyor belt as a device which is fed in a mixed state and is conveyed in one direction with various sorting objects having various specific gravity.

On the one side, the sorting object is supplied to the transfer unit 10, and the supplied sorting object is transferred in one direction by the transfer unit 10 and transferred to the sorting unit 20.

In the embodiment of the present invention, the sorting unit 20 is roughly divided into an air-blowing filter part 100 and a vibration selecting part 200 And the sorting objects taken over through the transfer unit 10 can be moved to the vibration selecting part 200 via the blowing part 100.

The blow-by screening part 100 includes a ballistic nozzle 120 arranged at a lower portion of the sorting object which is fed through the feeding unit 10 to be introduced and falls from the feeding unit 10 and is configured to eject air to the sorting object, An air blower 110 for generating a flow of air to move the air to the stick nozzle 120, a sorting object disposed in a direction in which air is injected through the ballistic nozzle 120, A tilting housing 140 to be mounted on the tilting housing 140 and a circulation path 150 arranged to circulate the air through the upper part of the tilting housing 140 and the blower 110.

The air filtering part 100 generates a flow of air in one direction through the blower 110. The air is sprayed through the ballistic nozzle 120 and is conveyed from the conveying unit 10 to be dropped into the tilting housing 140). In this process, a screened object having a large specific gravity falls down to a lower portion or flies over a relatively short distance, and a screened object having a relatively small specific gravity flies away.

Since the objects to be selected fall immediately depending on the specific gravity or the distances to fly by the air to be injected are determined differently, the flying distance varies depending on the specific gravity, Classification may be performed.

The tilting housing 140 is provided so as to be inclined upward along the direction in which air is injected.

(Not shown) may be formed in the bottom surface of the tilting housing 140 opposite to the direction in which the air is sprayed. First, through a discharge unit (not shown), a sorting object The tilting housing 140 can be lifted up to the end of the tilting housing 140,

The sorting objects having a relatively large specific gravity can not fly to the end of the tilting housing 140 where the discharge unit (not shown) is formed but fall before the tilting housing 140 and move along the inclination of the tilting housing 140 And enters the vibration selection part 200.

Specifically, the sorting object such as vinyl having a very small specific gravity can be immediately sorted through the blowing-in selec- tive part 100, and the sorting object such as a bottle or a can having a very large specific gravity falls immediately, ), And the sorted objects having a relatively intermediate specific gravity that requires a subdivided classification are introduced into the vibration selection part 200.

The flow of the air generated through the blower 110 is connected to the ballistic nozzle 120 through the main flow path 112 to move the air in one direction. In this process, the air is branched from the main flow path 112, And the exhaust passage 114 may be formed in a manner that the amount of the air in the blowing-out part 110 can be properly maintained, A part of the sorting object that can be introduced together with the air is prevented from entering the exhaust flow path 114. [

The ballistic nozzle 120 is formed in such a manner that air passing through the main flow path 112 flows into the lower part of the transfer unit 10 in one direction.

As shown in FIG. 5, a diffusion guide 130 may be provided between the diffusion part 126 and the airflow guide part 128.

The diffusion guide 130 generates a predetermined resistance in the air in the space of the inner surface through which the air flows, so that the flow of air can be injected evenly to the right and left without concentrating only on the central portion.

In detail, a plurality of guide wings 132, one end of which is coupled to the upper and lower ends of the inner space through which the air flows, and the free ends of which extend toward the center, The guide wing 132 and the guide wing 132 coupled to the upper portion and the lower portion may be spaced apart from each other by a predetermined distance so that the guide wing 132 and the guide wing 132 coupled to the lower portion do not interfere with each other.

In FIGS. 5 and 6, the arrangement of the guide wings 132 is arranged in a tooth-like configuration with a predetermined distance from the adjacent guide wings 132. However, .

In addition, the guide wing 132 may be formed of a material having elasticity so as to generate a resistance to the flow of air, but not to entangle or adhere to the sorting object that may flow along the air flow.

As shown in FIG. 6, the guide wing 132 may be formed such that the area of the guide wing 132 is wide at the center, and the area of the guide wing 132 is gradually reduced toward both the left and right sides. So that the resistance against the air flow at the center portion is largely generated and the resistance against the air flow is relatively reduced at both the left and right sides so that the air is more effectively distributed to the left and right sides.

When the sorting object is caught while moving along with the air on the guide wing 132 made of an elastic material, it can be discharged downward through the foreign object discharge port 124 by the self weight of the sorting object, 124 and the diffusion inducing guide 130 are formed adjacent to each other.
