Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power sorter for sorting objects to be treated, such as oversized garbage and construction waste, based on their specific gravity differences.

[0002]

2. Description of the Related Art A conventional wind sorter of this type is, for example,
As shown in Japanese Patent No. 2941600, a wind supply means comprising a blower provided with one end of a cylindrical sorter body inclined at a low angle, and a blower for supplying wind to the inside of the sorter body at one end of the sorter body. Is provided.

[0003] When an object to be processed is introduced from an inlet formed in the main body of the sorting machine, the weight of the object to be processed slides down the inner surface of the main body of the sorting machine by its own weight due to the inclination of the main body of the sorting machine. Is discharged to one end side, and the light weight object to be blown off by the wind power of the wind supply means is discharged to the other end side of the sorting machine main body.

[0004]

However, in the case of the conventional wind sorter, since the inclination angle of the sorter body, the wind force of the wind supply means, and the length of the body are all set to predetermined values, Under the fixed setting conditions, it is not possible to cope with various specific gravities, and the sorting accuracy is inferior, and the heavy and light weights are not finely sorted and are discharged in a mixed state. There are cases.

[0005] In view of the above problems, it is an object of the present invention to provide a wind separator capable of dealing with workpieces having various specific gravities.

[0006]

In order to solve the above-mentioned problems, a wind separator according to claim 1 is a cylindrical separator main body 1.
0 is provided so as to be inclined so that one end thereof is lowered, and a wind supply means 40 for sending wind into the inside of the sorter main body 10 is provided on the one end side. To be processed 5 input from the input port 13
0 is discharged to one end side of the sorting machine body 10 due to the inclination of the sorting machine body 10, and is discharged to the other end side of the sorting machine body 10 by the wind of the wind supply means 40. In a wind separator which is sorted into a lightweight object 50b, the separator main body 10 is provided to be tiltable, and the tilt angle of the separator main body 10 is adjustable.

Therefore, the tilt angle of the sorting machine main body 10 can be changed in accordance with the specific gravity of the composition of the processing object 50. For example, the weight of the processing object 5
0a and the specific gravity difference between the lightweight object 50b are large,
When the tilt angle of the sorting machine body 10 is set small and the specific gravity difference between the two workpieces 50a and 50b is small, the tilting angle of the sorting machine body 10 is set large so that the two workpieces 50a and 50b are separated. It is discharged in a state where they are surely separated without being mixed.

In the wind separator according to a second aspect of the present invention, a plurality of grooves 25 are formed on the inner surface of the separator main body 10 along the axis of the separator main body 10.

Therefore, irregularities are formed on the inner peripheral surface of the sorting machine main body 10 by the grooves 25, and the unevenness makes it difficult for the workpieces 50 to interfere with each other. The contact area between the inner surface of the sorting machine 10 and the inner surface of the sorter main body 10 is reduced, and the to-be-processed object 50 is tilted by the sorter main body 10 and the air supply means 40 is turned off. Sorting machine body 10 by wind
The workpiece 50 is discharged without stagnation.

Moreover, since the grooves 25 are along the axis of the sorting machine main body 10, the wind is rectified, and the workpieces 50 are discharged in a state of being aligned along the grooves 25. .

Further, in the wind separator according to the third aspect, the air volume of the wind supply means 40 can be adjusted, and
Is adjustable.

Therefore, in addition to changing the inclination angle of the sorting machine body 10 as well as the wind force of the wind supply means 40 and the length of the sorting machine body 10, each setting condition is adjusted or each setting condition is combined. Thus, the processing target 50 having various specific gravities can be easily selected.

Further, by increasing the axial length of the sorting machine body 10, even if the heavy workpiece 50b is blown to the other end side by wind force, it may strike the inner surface of the sorting machine body 10 and slide down to one end side. And the weight of the object to be treated 50b
Is not discharged from the other end of the sorting machine body 10.

The configuration of the wind separator will be described with reference to FIGS.
The wind separator 1 includes a frame 3, a cylindrical separator main body 10 supported to be tiltable on the frame 3, and a tilt angle adjuster 30 for adjusting the tilt angle of the separator main body 10.
And a wind supply means 40 composed of a blower for blowing wind into the inside of the sorting machine body 10.

The frame 3 has a support frame 5 having a rectangular shape in a plan view using a plurality of steel columns 4 having a U-shaped cross section.
The support frame 5 is supported by four columns 6 having a U-shaped cross section. A pair of rear support pieces 7 are erected on both rear sides of the support frame 5, and a pair of front support pieces 8 are erected on both front sides.

On both sides of the rear peripheral surface of the main body 10, a pair of shafts 11, 11 are coaxially protrudingly provided.
11 is rotatably supported by the two rear support pieces 7.

The tilt angle adjusting section 30 includes a pair of annular inserts 12 and 12 fixed to both sides of a front peripheral surface of the sorting machine main body 10, and a base of each of the inserts 12, 12. Two long adjusting rods 31 rotatably supported on
There are a plurality of adjustment holes 32 formed at a front end of the two adjustment rods 31 at a predetermined interval.

Then, a pin 33 is inserted into the adjusting hole 32 of the adjusting rod 31 and the insertion body 12 of the sorting machine body 10, and the sorting machine body 10 is moved to the rear end (one end) of the sorting machine body 10. And the front end (the other end) is supported at a high inclination.

In the case of FIG. 1, the angle formed between the main body 10 of the sorting machine and the horizontal plane is approximately 30 degrees. However, the adjusting hole 32 is appropriately formed according to the specific gravity of the object to be put into the main body 10 of the sorting machine. By making a selection, the tilt angle of the sorting machine main body 10 can be freely changed.

The sorting machine body 10 includes the sorting machine body 1
An inlet 13 is formed in the upper part of the peripheral surface of the central part of the machine 0, a hopper 14 is fixed to the periphery of the inlet 13 and an outlet 15 is formed at the rear end of the main body 10 of the sorting machine. A discharge pipe 16 is drawn out from the outlet 15 in a vertical direction, and a storage box 17 is provided below the discharge pipe 16. The distance A between the rear edge of the inlet 13 and the front edge of the outlet 15 so that the outlet 15 is not located immediately below the inlet 13.
Is 0 or more.

And, on the inner surface of the sorting machine body 10,
A plurality of V-shaped grooves 25 along the axis of the sorter body 10.
Are formed. By the groove 25, the sorting machine body 10
Is deformed into a corrugated shape rather than a simple arcuate surface, and the objects to be processed put into the sorter main body 10 are hardly overlapped with each other, and the frictional resistance with the inner surface of the sorter main body 10 is reduced. The processed material can be discharged smoothly.

Further, since the groove 25 is formed along the axis of the sorting machine main body 10, the air flow in the outer peripheral portion of the above-described sorting machine main body 10 is rectified, and the object to be processed is formed in the groove 25. It is discharged from the sorting machine main body 10 in a state of being aligned along.

Further, the sorting machine body 10 is configured so that the distance from the input port 13 of the sorting machine body 10 to the front end side can be changed. That is, as shown in FIG. 3, a cylindrical body 20 having a peripheral surface having the same shape as the inner surface of the main body 10 is inserted into the front end portion of the main body 10 of the sorting machine. (Not shown) automatically. The state of the cylindrical body 20 in FIG. 1 indicates a state in which the cylindrical body 20 is retracted, and the distal end portion of the cylindrical body 20 slightly protrudes from the front end side of the sorting machine main body 10.

The wind supply means 40 is provided in the sorting machine main body 1.
0 is provided via a funnel-shaped duct 41 at the rear end, and for example, the wind power can be switched according to the magnitude of the current supplied to the blower by a strong, medium, or weak switch (not shown). .

Then, the wind of the wind supply means 40 is blown from the rear end side to the front end side of the sorting machine main body 10, and this air flow becomes faster toward the center of the cylindrical portion of the sorting machine main body 10. The closer to the outer periphery, the slower due to friction loss with the inner surface of the sorting machine body 10.

Next, a description will be given of a sorting operation of the processing object of the wind separator 1 having the above-mentioned configuration with reference to FIG.

First, when the difference in specific gravity between the weight of the workpiece 50a and the light weight of the workpiece 50b constituting the workpiece 50 is large, for example, the tilting angle of the sorting machine body 10 is 30 degrees, The air volume is set to “medium”, and the cylinder 20 is retracted as shown in FIG. That is, the tip of the cylindrical body 20 is made to slightly protrude from the front end of the sorting machine main body 10. Under these setting conditions, the hopper 14 of the sorting machine body 10
When the object 50 is put into the sorting machine body 10, the processing object 50 falls into the inside of the sorting machine body 10 through the inlet 13 of the sorting machine body 10.

At this time, the heavy object 50a is not scattered by the wind due to the inclination of the sorting machine main body 10 and the groove 25, and the inner surface of the sorting machine main body 10 is aligned with the groove 25a.
And is stored in the storage box 17 via the discharge port 15 and the discharge pipe 16 of the sorting machine main body 10.

On the other hand, the lightweight crushed object 50b is blown off by the wind of the wind supply means 40 and discharged from the front end opening of the sorting machine body 10 while drawing a parabola.

Next, when the difference between the specific gravity of the heavy workpiece 50a and the specific gravity of the light workpiece 50b is small, for example, the tilt angle of the sorting machine body 10 is 60 degrees, and the air volume of the air supply means is "strong".
And the state where the cylindrical body 20 is advanced. That is, the cylindrical body 20 is made to protrude forward from the front end of the sorting machine main body 10,
The sorter main body 10 is set in a longer state. Under these setting conditions, the object 50 to be processed is placed in the hopper 14 of the sorter main body 10.
Is thrown in, the heavy processing object 50a may be blown off by strong wind, but since the tilting angle of the sorting machine body 10 is large and the sorting machine body 10 is long,
The processing object 50a hits the inner surface of the sorting machine body 10 and the groove 2
5 and is stored in the storage box 17 in the same manner as described above.

On the other hand, even if the tilting angle of the sorting machine body 10 is large or the sorting machine body 10 is long, the lightweight crushed object 50b is blown off by strong wind, and the front end of the sorting machine body 10 It is discharged from the opening.

Here, a cyclone may be attached to the front end of the sorting machine body 10 to separate the air and the object 50 to be processed.

As described above, according to the above-described embodiment, the tilting angle of the sorting machine main body 10 is adjusted and the air supply means 40 is controlled by the difference in specific gravity between the heavy workpiece 50a and the light workpiece 50b. It can be easily dealt with by changing each setting condition of the adjustment of the wind force and the length of the sorter main body 10 individually or in combination. Further, the frictional resistance between the workpiece 50 and the inner surface of the sorting machine main body 10 is reduced by the groove 25, and the workpiece 50 at the time of discharge by the groove 25 is reduced.
, The sorting accuracy can be remarkably improved.

In the above-described embodiment, the shape of the sorting machine main body 10 is a cylinder, but may be a triangular, square or other rectangular cylindrical body.

Further, in the case of the above embodiment, the groove 2
Although the shape of 5 is V-shaped, it may be arc-shaped or concave. In short, the groove 25 deforms the inner surface of the sorting machine main body 10 so that the workpieces 50 do not easily interfere with each other, and the contact area between the workpiece 50 and the inner surface of the sorting machine main body 10 can be reduced. Any shape can be used.

The mechanism for tilting the sorting machine body 10 and the mechanism for adjusting the tilt angle of the sorting machine body 10 can be appropriately changed depending on the design, and is not limited to the illustration. For example, the sorter main body 10 may be rotated using a motor, and the sorter main body 10 may be inclined by controlling the rotation angle of the drive shaft of the motor. May be tilted using a cylinder.

Furthermore, a cylindrical body 20 is provided at the front end of the main body of the sorting machine 10 so as to be able to move back and forth so as to change the length of the main body 10 of the sorting machine. The length of the main body 10 may be changed by adjusting the distance between the main body 10 and the outlet 15.
However, in this case, as described above, the distance A between the rear peripheral portion of the inlet 13 and the front peripheral portion of the discharge port 15 is set to 0 or more, and the sorting machine main body 1 is expanded and contracted in accordance with the expansion and contraction of the sorting machine main body 10.
It is necessary to provide a mechanism for expanding and contracting the structure of the frame 3 supporting the “0”.

As means for changing the length of the sorting machine main body 10, a cylindrical body 20 having a peripheral surface of the same shape as the inner surface of the sorting machine main body 10 is provided at the front end of the sorting machine main body 10 so as to be freely retractable. However, a cylindrical body having the same cross-sectional shape as that of the sorting machine body 10 may be attached to and detached from the front end of the sorting machine body 10 with bolts or the like.

The object 50 includes, for example, crushed bulky waste, building waste, and the like.

[0040]

As described above, the wind separator according to the first aspect of the present invention is capable of freely adjusting the tilt angle of the main body of the separator, so that it is effective for selecting an object to be processed having a desired specific gravity. is there.

According to the second aspect of the present invention, since the groove is formed along the longitudinal direction on the inner surface of the separator main body, the contact area between the workpiece and the inner surface of the separator main body is reduced. Since the discharge of the objects to be processed is guided by the grooves, interference between the objects to be processed is prevented, so that there is an effect that sorting can be performed efficiently.

Further, in the wind power sorter according to the third aspect, by changing the wind power of the wind supply means or the length of the main body of the wind separator, the factors of the set conditions are increased, and the objects to be processed having various specific gravities are increased. Can be easily handled, and a more effective sorting effect can be expected.
