〔発明の利用分野〕
本発明は、主として船倉等に堆積された穀物類
を揚送する際に用いられる粉粒体揚送装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a granular material lifting device used mainly for lifting grains deposited in a ship's hold or the like.
小麦等の穀物類は、船倉等に堆積して輸送され
る場合が多く、このため荷揚げの際にはこれらの
粉粒体を揚送する装置が不可欠となる。
Grains such as wheat are often transported in piles in ship holds, and for this reason, a device for lifting these powders and granules is essential during unloading.

あるが、消費電力が極めて大きくなる欠点があ
る。 Conventionally, this type of apparatus has been known as a pneumatic transport type and a mechanical type using a bucket conveyor or a case conveyor. The former method sucks the powder through a nozzle provided at the tip of a vertical transport pipe, but it has the disadvantage of extremely high power consumption.

バケツトの取付間隔が大きく、また送り速度もあ
まり大きくできないため搬送能力を確保するため
に装置を大型化しなければならない。 A bucket conveyor has a structure in which multiple buckets are lined up on the conveyor to sequentially pull up powder and granular materials, and is advantageous in that it consumes less power and reduces power loss due to friction compared to the pneumatic transport type. However, since the intervals between the buckets are large and the feeding speed cannot be increased very much, the device must be enlarged to ensure sufficient conveying capacity.

擦による動力損失も大きくなる欠点がある。 The case conveyor lifts powder and granules by running a chain equipped with a scraping device inside a vertical case, and has the advantage that the lifting device can be made more compact because the filling rate in each case can be increased. However, it has the disadvantage that it cannot be applied to highly fluid powders and granules, and in addition, the case and chain wear is severe and power loss due to friction is also large.

209972号）。 In order to solve this problem, the applicant installed a conveyor with fins that rotates in the vertical direction, and directly below this conveyor, the powder and granules are sent to the conveyor by the rotating centrifugal force of a rotor for scraping up the powder and granules. An application has been filed for a lifting device (patent application filed in 1982).
No. 209972).
この先願発明により揚送装置の動力損失はかな

する動力が大きいという難点がある。加えて従来
装置及び先願装置では、船倉内の粉粒体が残り少
なくなつた場合に、最後の一粒まで揚送すること
が困難である。 Although the power loss of the lifting device has been considerably improved by this prior invention, there is a problem in that the power required to rotate the rotor is large because the friction loss from the time of taking in the powder to the time of scraping it up is large. In addition, with the conventional device and the device of the prior application, when there are only a few particles left in the hold, it is difficult to lift up every last particle.
本発明はかかる事情に鑑みて為されたものであ

る。 The conveyor 22 includes a belt 2 as shown in FIG.
4. A pair of side plates 2 erected on both edges of the belt 24
6. A large number of cases 30 are formed along the conveyor 22 and are configured by a plurality of fins 28 that cross the side plate 26 and receive the powder particles 14. Since the side plate 26 has flexibility and is installed in a wave shape,
The conveyor 22 can be turned over without any problem even at the upper and lower ends. The fins 28 do not necessarily have to be fixed at right angles to the belt 24, but may be inclined upward, or may be bent upward from the middle as shown in FIG. With this configuration, the powder filling rate of the case 30 can be improved.

い。 A rotor 32 is arranged directly below the conveyor 22, as shown in FIGS. 4 and 5. A plurality of blades 3 extending in the radial direction are provided on the outer surface of the rotor 32.
4 are fixed, and as shown in FIG. 6, the width dimension W 1 of each vane 34 is larger than the axial dimension W 2 of the vane 34 .

一対形成され、その口径は羽根３４の内側寸法と
ほぼ同一である。 On the other hand, the conveyor 22 and rotor 32 are covered with a casing 36 that extends in the vertical direction, as seen in FIG. The casing 36 has a discharge port 38 for the granular material 14 at its upper end and an intake port 40 at its lower end. As shown in FIG. 4, a pair of intake ports 40 for the granular material 14 are formed on both sides of the casing 36 in the rotor axial direction, and the diameter thereof is approximately the same as the inner dimension of the blade 34.
この構成により取入口４０から羽根３４の内側

３４の半径方向はケーシング３６によつて覆われ
ているから、粉粒体１４が飛散することはない。 With this configuration, the powder 14 flowing from the intake port 40 through the inside of the blade 34 is accelerated by the blade 34 and discharged upward by centrifugal force. Since the blades 34 are covered in the radial direction by the casing 36, the powder particles 14 are not scattered.

の高さ寸法（半径方向長さ）を調整して行なう。 Incidentally, according to an experiment using wheat as the powder material 14, approximately 25 t/h of wheat could be handled by a lifting device in which the diameter of the intake port 40 and the diameter of the rotor 32 were 165 mm, the width of the blades 34 was 200 mm, and the height was 25 mm. The power consumption of the rotor 32 was 0.2KW. Intake port 4
It is desirable to determine the size of 0 by experimentally determining the inflow amount of the powder and granular material 14, and the balance between the lifting capacity of the lifting device 10 and the inflow amount of the powder and granular material 14 is determined by the blade 34.
This is done by adjusting the height dimension (radial length) of.

出口３８から外部へ排出される。 Lifting device 10 of this embodiment configured as described above
works as follows. First, the lifting device 10 is hoisted up by a crane or the like (not shown), the conveyor 22 and rotor 32 are rotated, and the lower end thereof is lowered onto the powder and granular material 14 in the hold 12. Since the intake port 40 at the bottom of the casing is open, the powder and granular material 1
4 flows into the intake port 40 by gravity. The powder 14 is accelerated by the blades 34 of the rotating rotor 32 and is sent to each case 30 of the conveyor 22 by centrifugal force. The powder 14 in the case 30 is conveyed upward by the conveyor 22 and discharged to the outside from the discharge port 38.

判るように約90゜である。一方、先願装置の如く
取入口を羽根３４の外周部に設置した場合、この
角度は第７図Ａに示すように極めて大きなものと
なる。 At this time, the powder and granular material 14 flowing in from the intake port 40
is accelerated until it becomes approximately equal to the peripheral speed of the tip of the blade 34, so if the rotation speed of the blade 34 is set appropriately, a sufficient conveyance speed can be imparted to the powder or granular material 14. The rotation angle of the blade 34 from when the powder 14 flows into the blade 34 until it is discharged is about 90 degrees, as seen from FIG. 7B. On the other hand, when the intake port is installed on the outer periphery of the blade 34 as in the device of the prior application, this angle becomes extremely large as shown in FIG. 7A.
このため、本実施例の揚送装置１０は前記の角
度差分だけ摩擦損失が小さくなつて、消費動力も
その分だけ節約される。 Therefore, in the lifting device 10 of this embodiment, the friction loss is reduced by the above-mentioned angular difference, and power consumption is also saved by that amount.

分以下になることが理解されよう。 FIG. 8 shows a comparison of the power consumption of the device of the prior application and the device of the present invention, where the horizontal axis is the circumferential speed of the rotor 32 (m/s), and the vertical axis is the power consumption (wh/t).
It will be understood from this figure that the power consumption of the device of the present invention is less than half that of the device of the prior application.
なお、羽根３４の両端部は、第９図及び第１０
図のように補強リング３７を設けると、前述の機
能をそこなうことなく、羽根３４の強度を向上さ
せることができる。 Note that both ends of the blade 34 are shown in FIGS. 9 and 10.
By providing the reinforcing ring 37 as shown in the figure, the strength of the blade 34 can be improved without impairing the above-mentioned function.

取入口４０が形成されている。 FIG. 11 shows another embodiment of the present invention, in which two rotors 32 are installed in the axial direction, and intake ports 40 for the powder and granular material 14 are formed on both sides of the rotor in the axial direction below the casing 36. .
これによつて個々のロータ３２及び羽根３４を
より小型化できると共に取入口４０の数を増加さ
せることができる。 This allows the individual rotors 32 and blades 34 to be made more compact, as well as increasing the number of intake ports 40.

れ、摩擦損失を小さくすることができる。 Further, the intake port 40 may be formed as shown in FIGS. 12 and 13 as long as it is within the side surface area of the rotor 32. In FIGS. 12 and 13, since the intake port 40 is biased toward the discharge start point shown in FIG. 7, the distance from the inflow point to the discharge start point is shortened on average, reducing friction loss. Can be done.
さらに、第１４図及び第１５図に示すように、

同様な効果が期待できる。 Furthermore, as shown in FIGS. 14 and 15,
Even if the intake port 40 is circular, by installing a current plate 39 and moving the average inflow point closer to the discharge start point,
Similar effects can be expected.

いが容易となる。 FIG. 16 shows a chute 42 on one side of the intake port 40.
An example in which the two are connected is shown. In the device of the prior application, the intake port is formed on the outer peripheral portion of the blade 34, so the chute 42 cannot be used. However, in this embodiment, the intake port 40 is connected to the casing 36.
Since the chute 42 is formed on both sides of the ship, the chute 42 can be connected, and the powder 14 remaining on the floor 46 of the hold can be removed by using a shovel 44 or a vacuum cleaner, etc. It becomes easier to dredge the bottom.
