Air Injection Type Sorting Apparatus of Wastes}

The present invention relates to an air jet type garbage sorting apparatus, and more particularly, to an air jet type garbage sorting apparatus for sorting the target waste by specific gravity by injecting air to the target waste to be sorted.

In general, garbage emits odors, and rats, flies, etc. breed and worsen the living environment and are also harmful to public health. It also occupies valuable living spaces, discomforting people, hurting aesthetics and discomfort. As such, the waste is detrimental to the environment and must be disposed of in a container through a series of processes such as collection, transportation, intermediate treatment, and final disposal.

In Korea, according to the Waste Management Act (March 08, 1991, Act 4363), general wastes generated in cities are responsible for the appropriate collection and disposal of municipal governments such as wards, mayors and munitions. Certain wastes are the responsibility of the head of the establishment. Details on the collection, transportation, disposal and disposal of waste are specified in the Waste Management Act Enforcement Rules. In order to reasonably dispose of general waste, it must be correctly separated and collected from each household or building that discharges it. Garbage may be compressed at a transport vehicle or at an intermediate collection point in order to save transportation costs and land area. Also in cities, garbage can be transported through collection pipes.

As the Producer Responsibility Recycling Scheme (EPR) has been expanded since 2003, the recycling of waste is becoming an urgent issue.

Collected waste should be classified by component and sent to the production plant to be recycled as a raw material. It is preferable to save resources and environmental conservation. For this purpose, it is more important to select and separate only the necessary substances from the mixed waste. .

However, the conventional waste sorting device has the following problems in performing the sorting operation.

Third, even if a person selects or uses expensive equipment, it is difficult to maintain and significantly reduce the screening ability due to the economical inefficiency or frequent overload.

Fourth, in addition to the blower, separation through vacuum adsorption is performed, but in the related art, since a separate vacuum valve for separating the vacuum and the discharge section rotates attached to the outside, high precision must be maintained to prevent air leakage. Because of this, there is a problem that it is difficult to maintain a high degree of vacuum due to the poor site environment, and there is a problem that the production cost is high due to the difficulty of manufacturing.

An object of the present invention for solving the above problems is to provide an air jet type garbage sorting apparatus capable of precisely sorting garbage according to the difference in specific gravity by precisely adjusting the air pressure injected from the injection unit.

In addition, the second guide part 134 has a relatively smaller specific gravity than the garbage separated from the first guide part 132, and thus has a small influence on the transverse pressure of the air injected from the injection unit 120. To sort out large garbage.

In addition, the separation unit 130 may be configured to further include an induction roller 136 is disposed on the top of the pair of guides to guide the falling of the garbage to any one of the pair of guides.

It is possible. Here, when the cross section of the rotating unit 151 is formed in a polygon, it is preferable to form an octagonal shape or more so that garbage can be adsorbed to the outer surface of the rotating unit 151 smoothly.

In addition, a rotation driving shaft 153 is provided at the rotation center of the rotation unit 151 and is coupled to the rotation unit 151. The rotation driving unit 157 transmits a driving force to the rotation driving shaft 153 mounted on the rotation unit 151 to allow the rotation unit 151 to rotate counterclockwise as shown in FIG. 4.

The suction unit 150 includes a suction part 155 and a driving part 159 providing suction power to the suction part. The suction part 155 serves to provide suction force to the communication hole 151a provided on the surface of the rotating part 151 in the rotation axis direction. In this case, the driving unit 159 communicates with the suction unit 155 provided in the suction unit 150 to provide a suction force to the suction unit 155. In general, the driving unit 159 is a vacuum pump, but is not limited thereto.

The discharge path of the garbage in the suction unit 150 will be described later.

By this configuration, the air compression force of the injection unit 120 and the air of the suction unit 150 by one drive motor without having a separate drive unit 159 that provides the suction force to the suction unit 155. There is an advantage that can generate the suction force at the same time.

However, it is of course also possible to configure to generate an air suction force of the suction unit 155 using a separate vacuum pump.

Although not shown, a cyclone unit may be provided on the flow path of the circulation pipe 170 to separate the foreign matter contained in the air introduced through the suction unit 150 by a cyclone method.

As such, the present embodiment can effectively separate various foreign substances contained in the air sucked into the suction unit by providing the cyclone unit on the flow path of the circulation pipe, and can supply clean air to the injection unit side.

Next, referring to Figures 1 and 2, the specific path for sorting the waste in the air-jet garbage sorting apparatus will be described as follows.

First, the waste to be sorted is moved in the direction A1 by the guide unit 110 and falls in the direction of the nozzle inlet through which the air of the injection unit 120 is injected.

The garbage dropped by the air injected from the injection unit is sorted in the A2, A3 and A4 directions according to the size of the specific gravity.

Specifically, the relatively light garbage of vinyls is blown in the air jet direction A4 by the transverse pressure of the jetted air. Relatively heavy garbage, such as glass bottles, fall along the direction of gravity A2 without being greatly affected by the transverse pressure of the injected air. On the other hand, garbage such as plastic bottles and the like whose weight is intermediate between the vinyls and the glass bottles proceed in the air injection direction under the influence of the transverse pressure of the injected air and eventually fall by gravity (A3).

The garbage dropped in the A2 direction is guided to the first discharge unit 142 through the first guide unit 132 and is discharged to the outside through the first discharge unit 142 (A8).

The waste falling in the A3 direction is guided to the second discharge unit 144 through the second guide unit 134 and discharged to the outside through the second discharge unit 144 (A9 direction).

Meanwhile, the garbage moving in the A4 direction passes through the blocking unit 160, and the waste having a large area that does not pass the gap between the plurality of blocking rods 160a of the blocking unit 160 is blocked by the blocking rod 160a. It falls in the A5 direction and falls to the 2nd discharge part 144. FIG. The wastes dropped in this way are discharged to the outside through the second discharge unit 144 together with the wastes dropped in the A3 direction.

Garbage that has passed through the blocking unit 160 is moved toward the suction unit 150 and the surface of the suction unit 150 is primarily applied as the suction force acts through the communication hole 151a provided in the suction unit 150. Is adsorbed on.

And, the garbage having a relatively high specific gravity among the garbage adsorbed on the surface of the suction unit 150 is adsorbed on the surface of the suction unit 150 rotates to fall in the direction A6 at the point where the influence of gravity is greater than the suction force. .

The garbage having a larger suction force than the gravity acting on the object waste falls in the direction of A7 at the point C2 where the suction areas C1-C2 of the suction unit end.

As a result, the suction unit 150 sucks the air injected from the injection unit 120 to facilitate the circulation of the air, and has a suction area C1-C2 and a discharge area. It blocks the communication hole 151a of the suction unit 150 and prevents the suction force from being lowered.

Meanwhile, in the present embodiment, the garbage falling from the suction region C1-C2 provided with the suction force of the suction unit (A6 direction) and the garbage falling past the suction region C1-C2 (A7 direction) are the second discharge unit 144. To the outside in the direction of A9.

 However, if the two paths (A6 and A7 directions) have independent discharge paths, further selection by the difference in specific gravity is possible.

5 and 6, the discharge unit 240 in the present embodiment includes a first discharge part 242, a second discharge part 244, and a third discharge part 246. .

The first discharge part 242 and the second discharge part 244 have a structure similar to the first discharge part 142 and the second discharge part 144 of the first embodiment 100 described above. However, in this embodiment, as shown in Figure 6, the second discharge portion is configured to vibrate in the vertical direction. Accordingly, the relatively heavy garbage and three-dimensional garbage on the second discharge portion 244 rolls down to the lower direction of the second discharge portion 244 and moves to the third discharge portion 246, and is relatively light. Garbage and sheet-type waste are discharged to the outside along the moving direction of the second discharge unit 244.

On the other hand, although not shown, the vibration movement of the second discharge portion 244 may be implemented by the rotational movement of the drive motor.

In addition, the second discharge unit 244 is configured to change the inclined angle for effective sorting according to the use conditions or installation conditions, such as the type of waste to be sorted or the moving speed of the second discharge unit 244. desirable.

Referring to Figure 5, it will be described in detail the garbage movement path of the present embodiment.

However, in this embodiment, the second discharge unit 244 is characterized by vibrating movement, and thus, unlike the first embodiment 100, the second discharge unit 244 is characterized in that additional waste sorting is possible. have.

Specifically, the wastes dropped to the second discharge unit through the paths of B3, B5, B6, and B7 are three-dimensional waste or relatively heavy waste rolled off in the direction B10 by the vibrating screening process described above, and thus the third discharge unit 246. It is discharged to the outside in the B11 direction through. In addition, sheet-shaped waste or relatively light waste is discharged to the outside along the B9 direction along the movement path of the second discharge unit 244.
