DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for producing various types of powders (for example, in large plants and small-scale test facilities).
A powder or granule transporting powder having a particle diameter of 0.5 μm to 14 mm, a stone block, and the like, a powder and granule supply device for discharging the powder in the powder and particle transport container, The present invention relates to a method for discharging a granular material using a body transport container and a granular material supply device.

2. Description of the Related Art Conventionally, this type of powdery and granular material transport container has
Those having an inlet formed at the upper part of the casing were often used. Then, when the granular material is transported from the first point to the second point using the granular material transport container, at the first point, the granular material to be transported is thrown into the casing from the input port, After putting the lid on the charging port, it was transported to the second point, the casing was turned upside down with the charging port facing down, the lid was opened, and the powder was discharged from the charging port to the outside of the casing.

[0003]

However, this has the following disadvantages.

First, since the casing must be turned upside down when discharging the granular material at the second point, the operation is troublesome especially when the casing is large.

[0005] Secondly, with respect to the powdery material having a strong jetting property,
At the time of discharge, the particles are scattered and soar, so that not only the working environment is deteriorated, but also it is necessary to wait for sedimentation of the soared particles, and it takes a long time to complete the discharge of the particles. These problems are particularly acute in industries dealing with highly toxic and expensive granules, and their countermeasures require considerable capital investment, time and effort.

Third, in the case of a powder having poor fluidity or a powder having a high adhesiveness, even if the lid is opened with the input port facing downward to discharge the powder, the upper portion of the inside of the casing is not affected. As a result, a bridge of the granular material may be generated, and a part of the granular material may remain without being discharged from the casing.

[0007] In view of such circumstances, the present invention can easily carry out the discharging operation of the granular material even in a large casing, and is not affected by the type (jet flow) of the granular material. Powders and granules that can realize environmental conservation and rapid discharge, and that can prevent the generation of bridges and discharge all particles regardless of the type (fluidity, adhesion) of the powders An object of the present invention is to provide a transport container, a granular material supply device, and a granular material discharging method.

That is, the present invention according to the present invention, which relates to a container for transporting a granular material, has a casing, and an inlet and an outlet are formed at an upper portion and a lower portion of the casing, respectively. A lid is openably and closably mounted on the casing, and a cone-shaped valve is detachably attached to the discharge port with its apex facing upward, and the valve is gripped by the casing.
And a valve holding means that can be used . By employing such a configuration, it is possible to eliminate the necessity of turning the casing upside down when discharging the granular material.

Further, a seal member is provided at a contact portion between the casing and the valve. With such a configuration, the gap between the casing and the valve is closed by the seal member, which acts to improve the sealing performance of the granular material transport container.

[0010] On the other hand, the invention relating to the powder and granular material supply device of the present invention is a powder and granular material supply device applied to the above-mentioned powder and granular material transport container, which has a body, and a table can be moved up and down on the body. , A table elevating means for elevating and lowering the table, a lock means for fixing a casing of the granular material transport container on the table, a valve for supporting a valve of the granular material transport container on the machine body A supporting member is provided , and the bag is held by the valve gripping means of the granular material transport container.

The valve release means is provided . By adopting such a configuration, only by lowering the table by the table elevating means, the discharge port of the granular material transport container on the table is opened, and the granular material in the casing is discharged downward from the discharge port. The casing is fixed on the table by the lock means, and acts so that the casing does not rise from the table even when the table is moved up and down.

Further, constituted a valve of the powder or granular material transport container in accordance with the descent of the table is provided a valve fixing means for fixing to the valve supporting member. With this configuration, the valve is fixed to the valve support member by the valve fixing means, and acts so that the valve does not drop off from the valve support cylinder even when the table moves up and down.

[0012] Further, according to the invention of the method for discharging a granular material in the present invention, when the granular material in the granular material transport container is discharged using the granular material supply device, the granular material is discharged. The transport container is placed on the table of the granular material supply device so that its valve is located on the valve support member of the granular material supply device. The granule supply device is fixed on a table of the granular material supply device by locking means, and then the table is lowered together with the casing while the valve is held on the valve support member. By adopting such a configuration, when a bridge of the granular material occurs in the casing, when the casing is lowered, the apex of the valve acts so as to break the bridge from below.

Further, when discharging the granular material in the granular material transport container by using the granular material supply device, the valve of the granular material transport container is provided with a valve of the granular material supply device. It is placed on a table of the granular material supply device so as to be located on a support member, and then the casing of the granular material transport container is locked by the locking means of the granular material supply device. Then, the table is repeatedly moved up and down together with the casing while holding the valve on the valve support member. By adopting such a configuration, when a bridge of the granular material is generated in the casing, the top of the valve acts so that the bridge abruptly breaks down from below every time the casing is lowered.

When lowering the table,
The distance is adjusted to control the discharge amount of the granular material. With such a configuration, it works so that the discharge amount of the granular material can be easily controlled.

[0027] Powder and granular material transport container 1 and powder and granular material supply device 2
1 has the above-described configuration, and the following procedure is used to transport and discharge the granular material from the first point to the second point using the granular material transport container 1.

That is, the powder and granular material supply device 21 is located at the second point.
Is installed, at the first point, the granular material transport container 1
Is opened, and the granular material is charged into the casing 2 through the charging port 3. Thereafter, the granular material transport container 1 containing the granular material is transported from the first point to the second point. At this time, as described above, since the granular material transport container 1 has a high hermeticity, it does not occur that the granular material in the casing 2 leaks outside during transportation.

When the granular material transport container 1 arrives at the second point in this way, the granular material transport container 1
From the powder.

First, the locking means 41 is driven to fix the granular material transport container 1 on the table 23 of the granular material supply device 21. To do this, as shown in FIG. 8A, the table 23 is located at the container attaching / detaching position P1, and
As shown in (b), with the ram 46a of the air cylinder 46 protruding, the granular material transport container 1 is set on the table 23, and the ram 46a of the air cylinder 46 is retracted.
Then, as shown in FIG. 6A, the lock arm 43 is engaged with the handle 6 of the casing 2, and the casing 2 is fixed on the table 23 by the lock means 41. At this time, as shown in FIG. 5A, in a state where the flange portion 2b of the casing 2 and the seal member 9d of the valve 9 are in contact with the seal member 23a of the table 23 and the seal member 53c of the valve support cylinder 53, respectively. Powder transport container 1
Is fixed to the granular material supply device 21.

Next, the valve 9 is fixed to the valve support cylinder 53 by driving the valve fixing means 61, and the pin plunger release mechanism 31 is driven to release the gripping state of the valve 9, thereby powdering the valve 9. It is delivered from the granular material transport container 1 to the granular material supply device 21. To do so, the table elevating means 24 is driven to lower the table 23 from the container attaching / detaching position P1 by a predetermined distance D1 (for example, 5 mm) as shown in FIG. . Then, as shown in FIG. 7B, as the table 23 is lowered, the valve support cylinder 53 and the valve 9 are also lowered by the same distance D1, and the ball 56 is moved to the lower corner portion of the small diameter portion 52a of the shaft 52. To the outside of the valve fitting cylindrical portion 53a (to the side of the valve 9).
In this case, the valve 9 is fixed to the valve support cylinder 53 via four balls 56. Further, as the table 23 descends, FIG.
As shown in (b), the roller 37 is connected to the small-diameter portion 3 of the dog 32.
2b, the plunger engaging portion 33a of the arm 33 moves the pin plunger 12 into the spring 1
In order to push down against the elasticity of the pin 3, the pin plunger 12
Retreats away from the plunger engagement groove 9e of the valve 9, and the gripping state of the valve 9 is released. As a result, the valve 9 is transferred from the granular material transport container 1 to the granular material supply device 21.

Finally, the table elevating means 24 is driven to discharge the granular material in the casing 2 of the granular material transport container 1. To do so, as shown in FIG.
A predetermined distance D2 (for example, 1
00 mm), and is positioned at the granular material discharge position P3. Then, while the valve 9 is held on the valve support member 51, the casing 2 moves down by the same distance D2 in conjunction with the table 23. As a result, the valve 9 is relatively pushed up in the casing 2, the outlet 7 of the casing 2 is opened, and the valve 9 and the casing 2 are opened.
A drop passage 14 is formed between the chute portion 2a and the chute portion 2a, so that the granules fall from the discharge port 7 through the fall passage 14 and are discharged below the granule supply device 21. Here, when controlling the discharge amount of the granular material, by adjusting the distance D2 for lowering the casing 2,
The discharge amount can be easily controlled by increasing or decreasing the opening area of the falling passage 14. At this time, since the casing 2 is fixed on the table 23 by the lock means 41, the casing 2 does not rise from the table 23 as the table 23 is lowered, and the valve 9 is fixed to the valve support cylinder by the valve fixing means 61. Since the valve 9 is fixed to the valve 53, there is no possibility that the valve 9 will fall off from the valve support cylinder 53 when the table 23 is lowered.

As described above, since the inlet 3 and the outlet 7 are formed in the upper and lower portions of the casing 2 in the granular material transport container 1, respectively, the conventional granular material transport container (the upper portion of the casing is charged). Only the mouth is formed)
Unlike this, since the casing 2 does not need to be turned upside down when discharging the granular material, the discharging operation of the granular material is simplified regardless of the size of the casing 2.

In addition, when the jetting property of the granular material is strong, there is a concern that the working environment may be deteriorated or the required time may be prolonged due to the scattering of the granular material. However, as shown in FIG. The flange portion 2b of the casing 2 even when the
The seal member 23a is interposed at the contact portion between the table and the table 23, so that there is no possibility that the powder in the casing 2 leaks to the outside through the gap between the table 23 during the discharge of the powder. Regardless of the strength of the jet of the body, the granular material can be discharged in a short time while maintaining the working environment.

By the way, with regard to the powdery material having poor fluidity or the powdery material having strong adhesion, since the bridging of the powdery material tends to occur at the upper portion in the casing 2, the casing 2 is repeatedly raised and lowered. Thus, the powder is discharged while collapsing such bridges. In other words, the table elevating means 24 is driven to move the table 23 up and down several times with a constant amplitude around the granular material discharge position P3. Then, the casing 2 moves up and down in the same manner in conjunction with the table 23. At this time, since the valve 9 is stationary on the valve support member 51, when a bridge of the granular material occurs in the upper part in the casing 2, , Casing 2
Each time is lowered, the apex of the valve body 9a of the valve 9 breaks this bridge from below. Therefore,
Even for powders with poor fluidity or powders with strong adhesion,
The bridges in the casing 2 can be prevented from remaining, and the powder can be entirely discharged. Also in this case, since the casing 2 is fixed on the table 23 by the lock means 41, the casing 2 does not rise from the table 23 as the table 23 moves up and down, and the valve 9 is supported by the valve fixing means 61. When the table 23 is moved up and down, the valve 9 is fixed to the cylinder 53.
From the valve support cylinder 53,
The discharging operation of the granular material is performed without any trouble.

Thus, the casing 2 of the granular material transport container 1
When all of the powdery particles in the container have been discharged, the valve is closed in a procedure reverse to the procedure described above. That is, the table 23 is raised from the powder discharge position P3 to the valve delivery position P2. Then, the casing 2 rises, and the valve gripping means 10 reaches the height of the body 9b of the valve 9. Further, the table 23 is raised from the valve transfer position P2 to the container attaching / detaching position P1. Then, the valve 9 is transferred from the granular material supply device 21 to the granular material transport container 1.

As described above, since the operation from the attachment / detachment of the valve 9 to the discharge of the granular material can be performed only by the raising / lowering operation of the table 23, the structure of the granular material supply device 21 can be simplified, and the granular material supply device 21 can be simplified. This leads to downsizing and cost reduction of the entire system including Further, since each of the granular material transport container 1 and the granular material supply device 21 has an independently sealed structure, the granular material transport container 1 is separated from the granular material supply device 21 after the discharge of the granular material. Also, the granular material does not scatter outside from the granular material transport container 1 or the granular material supply device 21.

In the above-described embodiment, the powdery and granular material transporting container 1 in which the hollow conical valve 9 is attached to the circular discharge port 7 has been described, but the shapes of the discharge port 7 and the valve 9 are not limited thereto. Instead, for example, a square pyramid-shaped valve may be attached to a square outlet.

[0038]

As described above, according to the invention relating to the powdery and granular material transporting container, the present invention has a casing, and an inlet and an outlet are formed at the upper and lower portions of the casing, respectively. A lid is attached to the opening so that it can be opened and closed freely,
A conical valve is removably attached to the outlet with its apex pointing upward, and the valve is grasped on the casing.
Since it is configured by providing a valve holding means that can be held, it is not necessary to turn the casing upside down when discharging the granular material, so that the granular material can be easily discharged even if the casing is large. A transport container can be provided.

Further, since a seal member is provided at a contact portion between the casing and the valve, a gap between the casing and the valve is closed by the seal member, and the sealing performance of the powdery and granular material transport container is improved. Therefore, environmental protection and rapid discharge can be realized without being affected by the type (granularity) of the granular material.

On the other hand, according to the invention related to the granular material supply device of the present invention, the granular material supply device applied to the granular material transport container has a machine body, and a table is attached to the machine body. A table elevating means for raising and lowering the table is provided, a lock means for fixing a casing of the granular material transport container on the table is provided, and a valve of the granular material transport container is supported on the machine body. A valve supporting member is provided , and the powder carrier is held by a valve holding means.
Release the gripping state of the valve with the lowering of the table
Since the valve release means is provided , the discharge port of the granular material transport container on the table is opened only by lowering the table by the table elevating means, and the granular material in the casing moves downward from the discharge port. While being discharged, the casing is fixed on the table by the locking means,
Since the casing does not rise from the table even when the table is moved up and down, it is possible to provide a powder and granular material supply device capable of easily performing the discharging operation of the powder and granular material.

Further, since the valve of the powder or granular material transport container in accordance with the descent of the table which is configured by providing a valve fixing means for fixing to the valve support member, the valve is fixed to the valve supporting member by a valve fixing means In addition, since the valve does not fall out of the valve support cylinder even when the table is moved up and down, the discharge operation of the granular material can be performed without any trouble.

Further, according to the invention related to the method for discharging powdery and granular materials of the present invention, when discharging the powdery and granular materials in the above-mentioned powdery and granular material transport container using the above-mentioned powdery and granular material supply device, The granular material transport container is placed on the table of the granular material supply device so that its valve is located on the valve support member of the granular material supply device, and then the casing of the granular material transport container is removed. The powder and granular material supply device is fixed on a table of the powder and granular material supply device by a locking means, and then the table is lowered together with the casing while the valve is held on the valve support member. Therefore, if bridging of granular material occurs in the casing, the top of the valve will break the bridge from below when the casing is lowered, so that the bridge does not matter regardless of the type of granular material (fluidity, adhesion). Departure Granular material discharge method capable of by preventing drain completely granular material can be provided.

Further, when discharging the granular material in the granular material transport container by using the granular material supply device, the valve of the granular material transport container is provided with a valve of the granular material supply device. It is placed on a table of the granular material supply device so as to be located on a support member, and then the casing of the granular material transport container is locked by the locking means of the granular material supply device. Fixed on the table, thereafter, the table is repeatedly lifted and lowered together with the casing while holding the valve on the valve support member, so that when a bridge of the granular material occurs in the casing, Each time the casing descends, the top of the valve breaks the bridge from below many times, preventing the generation of bridges regardless of the type of powder (fluidity, adhesion) and leaving no powder Let out It is possible to provide a granular material discharge method.

When lowering the table,
