The rotating drum 100 is formed in a cylindrical shape, rotatably supported by the support frame 110 of the apparatus, and is rotated by receiving a driving force from the drum rotation driving means 120.

The drum rotation driving means 120 will be described in detail. As shown in FIG. 3, the driven roller 121 and the driving roller 122 respectively positioned on the support frame 110 and in contact with the rotating drum 100. ; It is composed of a drive motor 124 connected to the pulley 123 to generate a driving force to transfer the driving force to the driving roller 122.

More preferably, the inner surface of the rotating drum 100 is coated with a rubber coating member (not shown). This prevents the waste of the mixed waste from being broken while falling, and reduces the corrosion and drop impact noise of the rotating drum 100 due to moisture.

The inner surface of the rotary drum 100 may further include a plurality of bucket members 150 formed at predetermined intervals in the circumferential direction so as to spread the mixed waste provided from the feeding means 300. The mixed waste introduced into the rotating drum 100 may be raised to a certain height due to friction with the inner surface of the rotating drum 100, but may be pushed up by the bucket member 150 to increase the drop height. As it is raised and dropped at a certain point in time, the mixed waste is dropped by the blowing air blown through the blowing duct 530 which will be described later, and the light waste is blown to one side of the cover duct, and the heavy waste will be described later. It is delivered to the other cover duct 520 is discharged to the outside.

The bucket member 150 is preferably made of a plurality of bucket members varying the angle of the extended end extending from the inner surface of the rotating drum 100. This makes it possible to provide a more efficient sorting operation by dispersing the dropping time by varying the fall time of the mixed waste is dropped by the bucket member 150 to fall.

That is, the plurality of bucket members 150 may be a group of straight bucket members composed of a plurality of straight bucket members formed linearly extending from an inner surface of the rotating drum 100 and a plurality of bucket members extending at different angles from the straight bucket members. It consists of an inclined bucket group consisting of an inclined bucket member. Preferably, each straight bucket member of the straight bucket member group and each inclined bucket member of the inclined bucket group are alternately arranged.

On the other hand, the bucket member 150 may be configured in a fixed manner, but when the garbage of more than a predetermined weight, the bucket member 150 can be rotated by the weight without the need to go to the highest fall point Possible bucket members 150 may be selectively configured.

Figure 4 is an example of a rotatable bucket member that can be configured in the rotating drum constituting the air flow selector of the present invention, the elastic support of the bucket strip 151 and the bucket member 150 connected in the form of a two-section link It is composed of an elastic support member 152. Such a bucket member 150, when the rotary drum 100 is rotated in a state in which rubbish having a predetermined weight or more is loaded, the weight of the elastic support member 152 (for example, leaf spring, etc.) by its weight at a predetermined height. It is possible to fall at a predetermined drop point even if it does not climb to the highest drop point while winning the elastic force.

This helps to prevent some of the trash that is likely to break, such as glass bottles, to fall from the highest fall point and bump into other trash.

Next, the closed-loop connecting duct means (510 to 550) closes one side of the rotary drum 100, the lower side is open, one side cover duct having a predetermined space therein; The other cover duct 520 which closes the other side of the rotating drum 100, has a lower portion open, and has a predetermined space therein; A blowing duct 530 connected in communication with an upper portion of the other cover duct 520 and for introducing blowing air into the rotating drum 100; A first connection duct 540 connecting the cover duct 510 to the cyclone separator 400; And a second connection duct 550 connecting the upper portion of the cyclone separator 400 and the blower duct 530. In the present invention, an embodiment in which the blower of the blower 200 described below is provided in the second connection duct 550.

The open lower portion of the one side and the other cover duct (510, 520) further includes a transport means 600 for transporting the waste falling through the lower opening. The conveying means 600 is a rectangular case 610 is formed in communication with the lower opening of the one side and the other cover duct (510, 520) as shown in FIG. A feed screw 620 rotatably provided in the rectangular case 610; And a drive motor 630 connected to the shaft of the transfer screw 620 via a connecting belt 631 to provide a rotational driving force to the transfer screw 620.

In the present invention, as an embodiment of the transfer means 600 is shown an example configured by a transfer screw method, it is not limited to this, it will be apparent to those skilled in the art that can be changed in various other ways, such as a conveyor method.

Here, the conveying means 600 of the other cover member 520 is a conveying means for discharging the heavy object to the outside, the conveying means of the one side cover member 510 is a conveying means for discharging the light weight object to the outside. .

The blowing means 200 is a general blowing means, impeller (not shown) installed at a predetermined position of the blowing duct; And a drive motor 210 providing a driving force to rotate the vane.

The injecting means 300 is not particularly limited as long as it can provide the mixed waste to the rotating drum 100 through the one side cover member 510, for example, a conveyor method or a transfer screw method may be employed. The figure shows an example of the conveyor system.

On the other hand, according to the present invention may further include a magnetic screening device (not shown) for magnetic force in the upper side of the input means 300 to be able to screen the steel waste in the mixed waste in advance.

The cyclone separation device 400 induces the air flowing through the one side cover member 510 to generate a swirl flow, and the ultra-light rubbish is separated from the ultra-light rubbish by using the centrifugal force generated by the swirl flow. Settled downward and discharged to the outside, the air is moved to the blowing duct 530 through the first connecting duct 540 and reused as blowing air provided to the rotating drum 100.

In addition, the lower side opening of the cyclone separator 500 further includes a discharge means 450 for discharging to the outside light weight that is separated from the air in the cyclone separator 500 to fall down.

On the other hand, the present invention is further provided with a filtering means 700 for filtering the air circulated on the connection duct (especially the blowing duct).

The filtering means 700 is composed of a rotary filter (not shown) located inside the connection duct (especially the blowing duct 530) and a drive motor 710 for rotating the rotary filter (not shown).

One side of the filtering means 700 is provided with a discharge means 750 for discharging the filtrate filtered by the filtering means.

The operation of the air volume selector according to the present invention configured as described above will be described with reference to FIG. 5 is an operational state diagram for explaining the operation of the air flow rate sorter according to the present invention. Arrows in the figure indicate the circulating flow of blown air.

As shown in FIG. 5, the operation of the air volume sorter according to the present invention is first introduced into the rotating drum 100 through which the mixed waste is rotated through the input means 300. In this case, when the magnetic separator is provided above the feeding means 300, the mixed waste is subjected to a process of sorting the steel waste among the mixed waste before being introduced into the rotary drum 100.

Subsequently, the mixed waste put into the rotary drum 100 is spun up by the bucket member 150 formed in the rotary drum 100 because the rotary drum 100 rotates, and falls at a predetermined height. At this time, since the extended end of the bucket member 150 is formed differently, the drop time is also dispersed.

In this manner, in the process of mixing and dropping the mixed waste by the bucket member 150, the blowing air supplied by the blowing means 200 is guided through the blowing duct 530 of the closed-loop connecting duct means to cover the other side. Heavy light weight (e.g., soil, sand, light plastics, thick paper, etc.) and light weight waste (small labels) among the wastes blown into the rotating drum 100 through the duct 520 and dropped by the blowing air. Paper, lightweight vinyl, etc.) is moved to one cover duct 510, and the waste of weight continues to move to the other side of the rotary drum 100 and falls through the lower opening of the other duct cover 520 to the conveying means 600. Is discharged to the outside.

Subsequently, among the light and light weight wastes moved to the one side cover duct 510, the light weight waste falls out through the lower opening of the one side cover duct 510 and is discharged to the outside by the transport means 600. The lightweight garbage is moved to the upper side of the one side cover duct 510 by the flow of blowing air and is moved to the cyclone type separator 400 through the first connection duct 540.

The lightweight waste moved to the cyclone separator 400 is settled downward by the swirl flow generated in the cyclone separator and discharged to the outside by the discharge means 450.

Thereafter, the blowing air moving upward of the cyclone separator 400 is guided to the blowing duct 530 through the second connection duct 550 by the blowing means 200 again, and the recycling of the blowing air continues.

At this time, the ultra-light rubbish mixed into the blowing air moving upward of the cyclone separator 400 is filtered by the filtering means 700 provided on the blowing duct 540, and the filtered filtrate is discharge means 750. Is discharged to outside.

Summarizing the sorting method using the air flow rate sorter according to the present invention operating in this way, to put the mixed waste into the rotating drum installed obliquely; Rotating a rotating drum such that the mixed waste falls; Firstly sorting ultra-light / light weight garbage and heavy weight garbage among mixed waste falling by blowing air from one side of the rotary drum to the other side; Secondly sorting the ultralight rubbish and the light matter rubbish moved to the other side by the blown air; Directing the ultra-light garbage to the cyclone sorting apparatus together with the air blown to sort the air and the ultra-light garbage three times; Guiding the air used in the tertiary sorting to be used as the blower air of the primary sorting, wherein the air blown in each process is to form a recirculation flow through the connecting duct means of the closed loop form.

The air flow rate sorter according to the present invention configured as described above is closed in the circulation cycle duct (connection duct) to which the blowing air is moved to the outside environment, so that dust or dust generated does not fly to the outside. In addition, since the screen is multiplely selected by the rotating drum, one side and the other cover duct, the cyclone separator, and the filtering means, there is an effect of increasing the sorting accuracy.

The sorting accuracy that can be implemented by the air flow sorting device according to the present invention is more effective to sort out only the sorting waste to be separated by separating the first sorted waste with other lightweight and ultra-lightweight waste in the preceding process, Particularly in the case of waste plastics that can be used as diesel alternative fuels, the waste plastics that have been screened can be reliably sorted from other lightweight waste such as paper labels, soil, dust, etc. Can be used directly in recycling systems without additional screening.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes within the scope not departing from the technical spirit of the present invention are possible in the art. It will be evident to those who have knowledge of.
