DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to an embodiment shown in the drawings. In FIG. 2, a rice storage tank D is installed in a house, receives and stores rice grains from the upper part through the transport path 2, and discharges the same from the lower part.

In FIG. 1, a rice transport vehicle 40 is detachably connected to the rice storage tank D by a suction air path 1A and a transport path 2A, and can discharge a predetermined amount of rice. The rice transport vehicle 40 includes a car body 41, a rice grain tank 42, a weighing / discharging member 43 provided at a lower end thereof, and a detachable connector 2C connected to the weighing / discharging member and provided at the other end. And a suction blower connected via a suction air passage 1A and a connector 1C detachably connected to the suction air passage 1 of the rice storage tank D via a conveyance passage 2A connected to the conveyance passage 2 of the rice storage tank D It has a device 44. As shown in FIG. 13, the weighing / discharging member 43 is a known one. As shown in FIG. 13, discs 43b are fixed concentrically to both end surfaces of a rotating shaft 43a, and a plurality of partition plates 43c are provided at regular intervals radially from the rotating shaft 43a. When one section between the partition plates coincides with the discharge port at the lower end of the tank 42, rice enters the section and is discharged by rotation of a stepping motor (not shown).

In FIG. 2, the rice grain storage tank D includes an air flow transport device 10 having a transport path 2 from the rice transport vehicle 40 connected to an upper portion thereof, and a suction air path 1 connected to the upper surface of the air flow transport device. It has a weighing and discharging member 16 provided at the lower end.

Referring to FIGS. 3, 4, and 5, the air flow transfer device 10 is configured as follows. The device casing 13 has a cylindrical body 13a having a vertical axis, the lower part of which is conically reduced in diameter, and a lid 13b made of a disk provided at the upper end. One end of the suction air passage 1 is opened to the suction port 13c on the upper surface of the lid via the filter F, and the other end is connected to the suction blower device 44.
A transport path 2 for transporting articles such as rice to the side wall of the apparatus main body 13a in a direction intersecting with an extension of the suction air path.
Are connected through the transfer port 13d.

Between the suction port 13c and the transport port 13d, the first is such that the transport path is left perpendicular to the extension direction and the lower end substantially corresponds to the center position on the extension of the transport path.
An airflow control plate 11a protrudes downward from the lower surface of the lid 13b.

That is, the U-shaped mounting piece 1 is provided on the upper surface of the lid 13b.
1f is fixed, and a fixing plate 11a penetrates through the lid and hangs down from the lower end. The fixing plate 11a extends in a vertical plane,
It is fixed between the side walls on the diameter of the main body 13a.

The movable plate 1 is guided by the fixed plate 11a.
1b is slidable up and down. The movable plate 11b has a movable main body 11c having substantially the same shape and size as the fixed plate 11a, and the lower end thereof is an inclined surface 11d on the suction port 13c side. Further, an L-shaped bent portion 11e is integrally formed on the upper end of the movable main body 11c on the side of the transport port 13d. The lower portion of the adjusting screw rod 14 vertically passing through the upper portion of the mounting piece 11f is vertically screwed through the bent portion 11e.

The second airflow control plate 12 is connected to the first airflow control plate 11 so as to sandwich the suction port 13c together with the first airflow control plate 11.
Protruding at a predetermined angle (45 degrees in the figure) with respect to the airflow control plate 11, the tip is separated from the first airflow control plate by a predetermined minute distance, and a slit (gap) G is formed. I have. The second airflow control plate 12 is firstly moved from the lower surface of the lid 13b.
It is inclined toward the lower end of the airflow control plate 11 and is fixed between both side walls of the main body. In this way, both control boards 1
An intermediate section C is defined between sections 1 and 12 and between both side walls of the main body. The upper part of the second airflow control plate 12 is a perforated plate 12b such as a wire mesh.

Here, as the means for changing the distance between the first airflow control plate 11 and the second airflow control plate 12, the adjusting screw rod 14 is used.

Inside the apparatus main body 13a, there is provided a cushioning material 15 for buffering scattering of articles (rice, etc.) or falling. A discharge member 16 is provided at a lower end of the main body. The discharge member (shutter) 16 is a known one, and the plate body 1 that moves up and down
When the cylinder 6a is moved up and down by the electric cylinder 16b and rises, rice is discharged.

The operation state will be described above. When the air suction device 44 is activated, the first airflow control plate 11 and the second airflow control plate 12 turn the suction air into a film-like shape. The air is swirling (spiral)
It becomes an air current.

The reason for the eddy current is considered as follows. In FIG. 6, the air flow has a gap G at the boundary between the first and second control plates as a bottom side, and a transport port 13d and a suction port 13c.
To form two triangular films with. The flow velocity V1 on the center line of the triangular transport path is larger than the flow velocity V2 on both hypotenuses of the triangle. Due to these speed differences, stress (strain) is generated in the airflow film, which is transmitted as a vortex into the transport path, and generates a screw (spiral) airflow that advances in the axial direction in the transport path.

Therefore, the rice tank 42 of the rice transport vehicle 40
Through the weighing and discharging member 43, the articles such as rice are efficiently sent by the eddy current through the transport paths 2 and 2A, and are introduced into the main body 13a of the rice grain storage tank D. Then, the airflow is diverted to the suction air passage 1, the rice escapes from the airflow film, collides with the first airflow control plate 11 or the cushioning material 15, is decelerated, and is dropped and stored at the lower part of the main body. And it is discharged | emitted out of a main body from the discharge member 16 of a lower end.

In FIG. 5, the thickness t of the movable plate 11b
= 10 mm, and the distance (gap G) between the surface and the second control plate 12 is set to 0.5 mm, which is the minimum gap. Then, when the adjusting screw rod 14 is turned to raise the movable plate 11b, the interval between the inclined surface 11d and the second control plate 12 is increased, and the flow rate of the airflow therebetween is increased. When the movable plate 11b is at the upper limit position, the fixed plate 11a and the second
The distance from the control plate 12 is 10.5 mm, which is the maximum gap. When the value of the gap G is insufficient with respect to the required flow rate, the perforated plate portion 12b serving as an auxiliary flow channel provided in the second control plate 12 responds.

Next, experimental results when rice is transported in an eddy current by the method and apparatus of the present invention will be described. The diameter D of the device body 13a is 400 mm, the length H of the first control plate 11 hanging from the device lid 13b is 100 mm, the angle R of the second control plate 12 with respect to the first control plate 11 is 45 degrees,
Gap G = 0.5 mm of the second control plates, the opening diameter d ₁ = 38mm of the transport path, the distance h ₁ = 100 mm than the lid 13b,
Suction air path opening diameter d ₂ = 38 mm, capacity of air suction device 1.5 m ³ / min.

FIG. 7 shows an embodiment in which the opening position of the conveying path 2 can be adjusted up and down. The transport port 13d is formed by a vertically extending elongated hole. A mounting plate M made of a rubber plate is fixed to the end of the transport path 2 so as to penetrate the opening. Then, the mounting plate M is detachably mounted on the main body 13a with bolts covering the transport opening 13d. The vertical length of the mounting plate is considerably longer than that of the long hole 13d, and the mounting position can be changed vertically by the length. Slot 13d
Are provided with a plurality of bolt holes so that the mounting position can be changed.

If the position of the conveying path 2 is raised, the angle between the direction of the air flow from the conveying path to the lower end of the first control plate 11 and the direction of the air flow therefrom to the suction air path is, for example, about 90 degrees. Then, the air flow changes direction largely (about 90 degrees), and the degree of separation of the conveyed material from the air flow becomes extremely large.
Therefore, for example, lightweight objects such as powder and tea leaves are also efficiently separated, and the second control plate 12 and the filter F are not required on the suction port 13c side.

As described above, when the degree of the air flow direction change is large, the fluid resistance at the turning portion increases, and the flow rate of the air flow decreases, so that the transport amount (capacity) decreases.

Conversely, if the position of the transport path is lowered, the degree of the direction change of the air flow from the transport path to the suction port is reduced, and the transport capacity is increased. Practically, the range where the air flow from the conveyance path to the lower end of the first control plate and from there to the suction air path has a maximum angle of about 120 degrees (direction change of about 60 degrees) is superior.

In the above embodiment, the lower end of the first control plate 11 is straight and the gap G is also straight, and the airflow film has a flat shape on the side of the conveying path and on the side of the suction air path. But,
It is not always necessary to do so, and for example, as shown in FIG. 8, the boundary between the first and second control plates 11 and 12 may have an arc shape, and a curved film is formed accordingly. . Also, as shown in FIG. 9, in the case of a triangular mountain-shaped gap,
A triangular-shaped film is formed accordingly. As a result, the spread width of the film (length in the direction orthogonal to the center flow direction of the airflow) increases, and the degree of spiral airflow generation in the transport path increases. Thus, other forms of gaps G may be applied.

FIG. 10 shows the formation of the airflow film.
As described above, two control plates 11 and 12 are provided on the other side wall of the apparatus main body 13a at an angle to each other so as to leave a gap G therebetween. in this case,
The airflow film does not divert the flow. Also in this case, a spiral airflow is generated in the transport path.

FIG. 11 shows a state in which two control plates 11 and 12 are opposed to each other on one plane and approached with a gap G left therebetween.
Alternatively, a slit (a long hole) corresponding to the gap G in one plate
May be provided.

FIG. 12 shows a state in which the conveyance path and the suction air path are connected to the main body of the apparatus with a single plate as a boundary, with the conveyance path and the suction air path formed at an angle to each other or substantially in a straight line.
Also in this case, an airflow film is generated.

As described above, the present invention also includes the following three airflow conveying methods. (1) A plate-like member is protruded from a wall surface in a section, and with the plate-like member as a boundary, the conveyance path and the suction air path are formed at an angle to each other or substantially in a straight line so as to face each other. An air flow conveying method, wherein the air flow is formed by connecting to a wall and circulating air over the tip of the plate-shaped member to form an air film. (2) A plate-like member having a slit is provided on a wall surface in the section,
With the plate-shaped member as a boundary, the conveying path and the suction air path are connected to the partition wall at an angle to each other or substantially linearly opposed to each other, and the air film is passed through the slit of the plate-shaped member. Forming an air flow. (3) A conveyance path is connected to one wall of the section, and a suction air path is connected to the other wall of the section on a line intersecting an extension of the conveyance path, near a position where the extension lines of both paths intersect. And a control plate having a slit disposed therein, air is circulated through the slit to form an air film, and the air flow in the air film is changed in direction at the slit.

FIGS. 14, 15, and 16 show an embodiment of an air flow transfer device particularly suitable for transferring powder such as flour, but it is needless to say that the present invention can be applied to granules such as rice. The apparatus main body has a substantially rectangular parallelepiped shape with the upper wall horizontal, and the upper part of the side wall opposite to the side where the transport path 2 is connected is inclined toward the transport path 2 and connected to the upper wall. The first control plate 21 is made of three, to the extension line L ₂ of the inflow pipe plane wall position of the transport path 2, the left plate 2
1a is h _1, the middle plate 21b is h _2, the right plate 21c may lower the h ₃ up position. The second control plate 22 at right angles to the first control plate 21 comes close to exist a gap (slit) G, the slit G is positioned higher by h ₃ from the extended line L _2. The lower end of the right plate (adjustable movable plate) 21c is inclined at 45 degrees with respect to the vertical plane, and the tip of the second control plate 22 approaching it is inclined at 45 degrees upward with respect to the horizontal plane. Also, the second control plate 22
Also serves as the upper wall of the apparatus main body, and the first control plate 21, the second control plate 22, and the auxiliary plate 23 form an intermediate section C just above the gap G and above the upper wall of the apparatus main body, A suction air passage 1 is vertically connected to the center of the upper surface.

In this embodiment, when the powder is transported, the transport path 1
The spiral airflow in the inside becomes a film between the first control plate 21 and the direction is changed from the left plate 21a to the middle plate 21b to separate a part of the powder. Then the middle plate 21b is diverted by a large angle between the distance h ₃ extending into the gap (slit) G between the second control plate 22, most of the powder is separated somewhat horizontally, of the device body It collides with the inclined wall and is turned downward. Therefore, the amount of powder discharged from the suction air passage 1 through the gap G is extremely small, and it is not necessary to provide a filter.

Next, the experimental results will be described. The dimensions (unit: mm) of the model device used are shown in FIGS.
The experimental results of the powder separation performance are shown in Table 1.

Now, the characteristics of the airflow in the present invention will be considered. In a general swirling flow, the velocity distribution is slow and valley-shaped at the center as shown in FIG. On the other hand, in the "spiral flow" of the present invention, as shown in FIG. 19, the velocity distribution is steep in the flow direction and has a mountain shape, and the axial flow velocity Vz is extremely fast at the center of the pipe, and is near the pipe wall. slow.

Therefore, such a "spiral flow"
The features of the airflow transfer system using the following are as follows.
Due to the velocity distribution, the pressure at the center of the pipe is lower than that at the pipe wall,
The conveyed material is drawn to the center of the pipe. For this reason, the transported object has less collision with the inner wall of the pipe and has less wear. Due to the velocity distribution, the loss of the flow due to the wear between the air and the pipe wall is small, and the vortex is hard to disappear. For this reason, transport over a long distance becomes possible. Unlike the pressure feeding method, it is a suction method, and therefore, even if a conveyed substance (eg, powder or granules) is clogged in the pipe, it is easily removed and hardly clogged. Even fine powder (or liquid fine particles) can be separated from air without a filter (no clogging).

FIG. 17 shows still another embodiment. When the lower end of the first control plate 21 is inclined toward the slit G, the angle at which the airflow passing through the lower end changes its direction along the lower end inclined surface becomes larger. , Separation performance is increased. Further, facing the auxiliary slits G ₁ , G _2, ..., The upstream side edges of the slits become descending surfaces J ₁ , J _2, ..., And from their tapered lower ends, rise surfaces K ₁ , K ₂ ,. A rectifying member 24 reaching the downstream edge of the slit is provided. Thereby, the distance is maintained from the direction change point of the flow path to the slits G ₁ , G _2, ..., The degree of powder reaching the slits is reduced, and the separation performance is improved.

Here, the flow passage area of the suction air passage 1 is represented by S ₁ ,
The flow path area of the slit G (G ₀ , G ₁ , G ₂ ,...) Is Sg,
Assuming that the passage area of the transport path 2 is S ₂ , approximately S ₁ ≧ Sg ≧
It is desirable that the relationship S ₂ is satisfied.

The present invention can be applied to pneumatic conveyance of grains, granules, powders or fine particles.

The present invention is not limited to the examples and embodiments described above, but includes various modifications without departing from the spirit and scope of the claims.

[0046]

According to the present invention, the rice is transferred from the transport tank to the rice storage tank in the residence by the eddy current transport apparatus, so that the transport worker does not need to transport the rice bags, and the transport of rice is very easy. This is a work, so that only one transport worker can be transported sufficiently, and even those who cannot perform heavy labor such as the elderly can be transported.

Since the vortex air transport device may be used to transport rice to a rice storage tank installed in a residence such as a restaurant, rice can be transported even at midnight, and a worker in each store has conventionally been able to transport rice. The delivery time is not limited as in the case of delivery (transportation) within the time, and the transport efficiency can be improved.

By the eddy current, articles such as rice grains can be stably transported for a long distance without being clogged.

By the first and second airflow control plates, the air at the end of the transfer becomes strip-like (film-like) and a slight gap is formed between the control plates, so that the suction air and the transfer article (rice, etc.) can be transferred. Since the separation can be surely performed, there is no need to provide a special device for separating the articles, so that the configuration can be simplified.
