Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a capsule that can be transported through a pipe by a gas flow, and a loading machine at a specific point in the pipe can transport fine powder [coal, metals, food, and other various substances]. With regard to equipment that feeds fine powder by dropping and then discharges the fine powder inside the capsule by dropping it from an unloading machine at another location, there is a risk of environmental deterioration due to the falling supply of fine powder and the flying up of dust at the time of discharge, as well as a certain concentration of fine powder contained in the capsule. To prevent self-destruction that may occur under certain conditions,
The purpose is to enable loading and unloading operations to be carried out effectively while maintaining sufficiently high work efficiency.

First, embodiments of the present invention will be described based on the drawings.

1 to 4 show the sequential operation of the fine powder loading machine 2 to the capsule 1, which can be transported in the pipeline by a gas flow, and FIGS. The sequential operation of the fine powder unloading machine 3 is shown. 4 and 5 are capsule transport pipes (not shown)
Both the loading and unloading pipelines are open at the top and can be rotated together with the capsules as needed.

The capsule 1 has rolling wheels 6 arranged radially.
... and an opening 7 for loading and unloading in the center in the width direction.
a fine powder storage container section 8 formed of a container section 8, a lid 9 swingably supported on the container section 8 to open and close the opening section 7, and an automatic lid lock installed at the outer edge of the opening section 7. device 27 and an air filter 28 for internal air suction installed on the outer periphery of the opening 7
Inside the container part 8, top plates 10, 10 connected on both sides of the opening 7 are arranged at an angle slightly larger than the angle of repose of the fine powder. 11
and 12 are attachments for airtight contact with a valve case 18 and cover 15, which will be described later.

The loading machine 2 has a fine powder supply path 13 in a vertical position that can freely move near and far at a position above the capsule 1 in an open position with the lid 9 open, and communicates with the opening 7 when approached, and a fine powder supply path 13 in a vertical position that is interposed in this supply path 13. A rotary on-off valve 14 and a cover 1 surrounding the outlet of the supply path 13.
5, and a vacuum dust suction passage 16 communicating with the cover 15, the details of which are as follows.
The supply path 13 is configured with an inner cylinder 13a and an outer cylinder 13b which are fitted to be extendable and retractable in the axial direction,
The upper inner cylinder 13a communicates with the fine powder input hopper 17, and the lower outer cylinder 13b has a case 18 of the valve 14 and the cover 15 surrounding the case 18 connected to each other at its lower end. 18,19
1 is a bellows interposed between the inner cylinder 13a and the outer cylinder 13b for the purpose of a dustproof seal; 20, 20 is a pulling wire (or a cylinder rod may be used) connected to the cover 15; 16a is the suction path 1;
29 is a vacuum suction path for dust leaking from the sliding portion that communicates with the lower part of the bellows 19, 29a is a telescopic tube that constitutes the vertical portion of the same, and 21 is a suction air volume adjustment passage. It is an outside air intake with a filter.

The operation of this loading machine 2 is as follows.

[1] After the capsule 1 taken into the loading work conduit 4 is fixed in a predetermined position by a container locking device (not shown), the lid 9 is opened.

[2] Relax the wires 20, 20 (or drive the cylinder) to move the outer cylinder 13b downward, bring the valve case 18 and cover 15 into contact with the attachments 11, 12, respectively, and insert the valve ( When the vacuum pump (not shown) connected to the suction path 16 is opened to create a negative pressure inside the cover 15 and the container section 8 by a vacuum pump (not shown) connected to the suction path 16, the valve 14 is opened. Objects enter and fall into the capsule 1 through the supply path 13 and the opening 7 and are supplied. The dust leaking from the gap between the attachment 11 and the suction path 16
is transported to a designated treatment tank.

[3] When the tank is full, close the valve 14.
During this time, the fine powder enters the capsule container section 8 all at once, communicates with the hopper 17, the supply path 13, the valve 14, and the container section 8, and fills them all. Therefore, there is almost no amount of mixed air, and there is no possibility of dust explosion, including when it falls.

[4] Move the outer cylinder 13b upward by winding up the wires 20, 20 (or driving the cylinder). During this time, the dust suction action by the suction paths 16 and 29 continues. The amount of dust leaking from the sliding parts or attachments of both the inner and outer cylinders is extremely small, so it cannot reach a self-destruct concentration. At the upper limit of the rise of the outer cylinder 13b, the valve of the suction path 16 is closed, and the lid 9 is also closed. The container lock on the capsule 1 is then released and the capsule 1 is transferred to its transport line and transported along this line to its destination by means of a gas stream.

Next, the unloading machine 3 will be described. This unloading machine 3 is equipped with a fine powder loading capsule 1 which is vertically inverted with the lid 9 in a closed position in the unloading work conduit 5.
In contrast, the main part includes a fine powder discharge passage 22 in a vertical position that is movable near and far and close to the capsule 1 in a state in which it is close to the capsule 1 when approached, and a reduced pressure dust suction passage 23 that communicates with this discharge passage 22. It is said that The discharge passage 22 is composed of an inner cylinder 22a and an outer cylinder 22b which are fitted in a telescopic manner in the axial direction. opening and lid 9
The receiving hopper section 24 has a large capacity that can accommodate
is formed. Reference numerals 25 and 25 indicate a bellows for the purpose of a dust-proof seal, which is interposed between the inner cylinder 22a and the outer cylinder 22b, 23a is a telescopic tube that constitutes the vertical portion of the suction passage 23, 26 is an outside air intake port with a filter, and 30 , 30 is a pulling wire (or a cylinder rod may be used) connected to the hopper portion 24.

The operation of this unloading machine 3 is as follows.

[1] While the capsule 1 taken into the unloading work conduit 5 is fixed in a predetermined position by a container locking device (not shown), it is turned over 180 degrees in the vertical direction.

[2] By winding up the wires 30, 30 (or by driving the cylinder), the inner cylinder 22a, that is, the hopper portion 24 is moved upward and brought into contact with the capsule 1 and the lid locking device 27 on the outside of the lid 9, thereby locking the lid. When the lid 9 is released, the lid 9 is opened by the weight of the lid and the contained fine powder, and the fine powder is discharged through the hopper section 24 and the tubes 22a and 22b. At this time, since the internal fine particles fall through the sufficiently wide opening 7, they are easily replaced with outside air and discharged in a short time. In addition, since the capsule top plates 10, 10 are held at the angle of repose or higher, the entire amount is discharged to the outside of the container without any residue remaining. During this time, if vibration is applied to the hopper section 24, the falling will be further promoted.

[3] After all the fine particles in the capsule have fallen (set the timing with a timer, etc.), the suction path 23
Open the valve (not shown) located in the hopper part 2.
The rising dust inside 4 is quickly discharged to a designated treatment tank using a vacuum pump (not shown).
Close the valve again.

[4] After lowering the inner cylinder 22a, the empty capsule 1 is turned over 180 degrees vertically, and the lid 9 naturally closes and is locked.

Although the preferred embodiments have been described in detail above, the device for loading and unloading fine powder for gas transport type capsules according to the present invention is capable of loading and unloading fine powder at specific points in the pipeline for capsules that can be transported within the pipeline by a gas flow. The device is a device for supplying fine powder by a machine and dropping and discharging the fine powder in a capsule by an unloading machine at another location, and the capsule has a lid that can be opened and closed at a loading/unloading opening in the center in the width direction. The top plate connected to both sides of the opening is positioned at an angle slightly larger than the angle of repose of the fine powder, and the loading machine is movable near and far from the capsule in the lid-opening position. A fine powder supply channel in a vertical position communicating with the opening when approached, an on-off valve interposed in this supply channel, a cover surrounding the discharge port of this supply channel, and a reduced pressure dust suction channel communicating with this cover. In addition, the unloading machine is configured to be able to freely move near and far from the capsule that has been inverted in the vertical direction in the lid-closing position, and discharge fine powder in a vertical position that is in close contact with the capsule so as to surround the lid by approaching the capsule. It is characterized by having a vacuum-type dust suction passage communicating with the discharge passage, and can be used both during loading and unloading of fine particles into the capsule. The dust raised by falling particles is kept in a specific closed or nearly closed system and then vacuumed up and discharged to a designated processing section, resulting in environmental deterioration due to dust raised at loading and unloading work areas. In addition to reliably preventing this, during loading, the amount of air that enters until the container is full is extremely small.
Further, during discharge, the rising dust in the hopper portion is generated for a very short time and is highly concentrated, so that self-destruction of fine powder can be reliably prevented. Even so, while both the supply and discharge channels for fine powder are movable near and far from the capsule, negative pressure is applied inside the capsule during loading, allowing the powder to fall, and on the wholesale side, the powder is dropped through a sufficiently wide opening. Therefore, it has become possible to effectively prevent environmental deterioration and self-destruction while maintaining sufficiently high loading and unloading work efficiency.
