Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solid material transfer device that mainly transports solid materials such as fish, ham, and sausages using a liquid such as water as a transport medium, and in particular, the present invention relates to a solid material transfer device that transports solid materials such as fish, ham, sausage, etc. using a liquid such as water as a transport medium, and in particular, the present invention relates to a solid material transfer device that transports solid materials such as fish, ham, sausage, etc. using a liquid such as water as a transport medium. This invention relates to a transfer device that transfers solids by sucking them into and discharging them into a tank.

The conventional solid-liquid transfer device shown in FIG. 1 consists of a vacuum tank 1 and a vacuum pump 2.
The intake and exhaust lower at the upper end is connected to a vacuum pump 2 via a four-way valve 8, and its operation is performed by first discharging the air in the vacuum tank 1 with the vacuum pump 2. The solids are sucked into the vacuum tank 1 along with the liquid through the hose 5, and when the vacuum tank 1 is full, the four-way valve 8 is switched and the vacuum pump 2 pumps air into the vacuum tank 1. , solids and liquid are sent out together through a delivery hose 6.

Unlike ordinary pumps, this type of transfer device has the advantage of being able to transport solids without damaging them, as there is no impeller or the like in the path of solids. This type of transfer device, which is often used for transportation, requires a large-capacity vacuum tank because it is stored in a vacuum tank before being transferred, which severely limits the installation location and makes it difficult to use with other transfer devices. Despite having many excellent features, the places and applications in which they can be used have been severely restricted due to lack of space, difficulty in installation, and difficulty in transporting them.

This is because, for example, in the case of ships where this type of transfer device is most often used, it cannot be loaded on small ships that do not have space for a large vacuum tank, and even in the case of medium- to large-sized ships, it is difficult to carry the main ship from the hatch to the cabin. The current situation is that the equipment cannot be brought in, so the deck has to be cut with gas etc. before being brought in.

Fish pumps in which part of the vacuum tank is tubular are known.

(Utility Model Application No. 49-95195) However, by forming part of the vacuum tank into a tubular shape, it is impossible to install it in a confined space, which is the biggest drawback of this type of device. be.

In particular, when installing the tower on a small ship later, the ship itself needs to be significantly modified, making installation extremely time-consuming.
In addition, even with modifications, there were times when it was not possible to mount a vacuum tank of the required volume.

Furthermore, a vacuum tank formed in the shape of an elongated tube has the disadvantage that the bent piping is deteriorated in order to increase the volume, and the bent portions are more likely to be clogged with solid matter than conventional vacuum tanks.

Solids stuck in the pipe cannot be completely removed without disassembling the pipe.

However, once a long and narrow vacuum tank is installed on a ship, it cannot be removed from the tower, and if the vacuum tank becomes clogged with solid matter, subsequent processing becomes extremely time-consuming. .

In other words, conventional systems have the disadvantage that a large-volume vacuum tank cannot be easily and smoothly installed in a limited space divided into various shapes, and that it takes considerable time and effort to dispose of clogged solid matter. Ta.

As mentioned earlier, this type of solids transfer device has the excellent property of being able to transfer solids without damage, which cannot be achieved with other pumps, but due to the transfer principle, it requires a large volume vacuum tank. However, it has the disadvantage of being severely restricted in its installation location.

Therefore, if this drawback were eliminated, pumps of this type could be used in a significantly wider range of applications and their ideal characteristics could be exploited.

In order to eliminate this drawback, the present invention uses a flexible hose for the vacuum tank.An important object of the present invention is that the hose can be bent, curved, spirally wound, or straightened depending on the installation location. We provide a solid material transfer device that allows a vacuum tank to be installed in an empty space, can be installed in almost any location without being limited by installation space, and is easy to transport to the installation location. There is something to do.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The solids transfer device shown in FIG. 2 includes a flexible hose 9, which is a vacuum tank for sucking solids and water, and a branch pipe 23 and a check valve 10, 11 connected to the lower end of this hose 9. a suction hose 12 and a delivery hose 13 connected together;
The air means includes a four-way switching valve 15 connected to an air intake/exhaust port 14 which is an air port opened at the upper end of the hose 9, and a vacuum pump 16.

The hose 9 is a flexible hose that is not crushed by negative pressure but can be bent freely.

A delivery hose is connected to the lower end of this hose 9, since solids and liquids are discharged from the hose by being drained.

Further, the hose 9 is arranged at a downward slope at least toward the lower end so that all the liquid in the hose 9 flows out.

By the way, the inner diameter of the hose 9 is determined by taking into consideration the size and shape of the solid material to be transferred, as well as the space for the installation location, but generally, in order to make the volume as large as possible,
It is formed to be thicker than the inner diameter of the delivery hose.

If the hose 9 is formed in a spiral shape, as shown in FIG. 2, it is possible to arrange a vacuum pump in the central cavity.

The check valves 1o and ii connected between the suction hose 12 and the delivery hose 13 are ordinary check valves,
In other words, valves that transfer fluid only in a certain direction are generally used, but it is not always necessary to use this type of valve.For example, a normal on-off valve, that is, when open, fluid moves freely in any direction. You can also use what you can.

However, when using a normal on-off valve, it is necessary to open only the check valve on the suction hose side when sucking liquid into the hose, and only open the check valve on the delivery hose side when discharging liquid.

Therefore, in this specification, a check valve is not limited to a valve that allows fluid to pass in only one direction, but also includes a valve that allows fluid to pass in both directions when opened.

A float valve 17 is provided at the upper end of the hose 9 to detect that the hose 9 is filled with liquid.

Therefore, when the inside of the hose 9 is filled with liquid, the float valve 17 is activated and the discharge of air inside the hose is stopped.

The hose 9 shown in FIG. 2 is provided with an intake/exhaust port 17 at its upper end. With this structure, air flows into the upper end of the hose 9 during discharge, so the liquid in the hose flows out more smoothly. Even when liquid is sucked in, the air is removed from the top of the hose 9 and the liquid is sucked in from the bottom, so that the air inside the hose can be more smoothly discharged.

The solid material transfer device shown in FIG. 2 uses a single hose to suck in and discharge liquids and solids for transfer, so that the transfer is intermittent.

As shown in FIG. 3, two hoses 21 and 22 are connected in parallel, and liquid is sucked into one hose and discharged from the other hose, thereby allowing continuous or nearly continuous conveyance.

As mentioned above, the solid material transfer device according to the present invention uses a flexible hose as the vacuum tank, so it can be installed in places where conventional vacuum tanks cannot be installed, that is, places where there is no space for a large volume. However, they can be placed in the unused dead space that almost always exists,
It can be installed in narrow spaces where it would have been impossible to install with conventional equipment, and since it makes effective use of unused pot space, a large vacuum tank does not get in the way after installation, and it It is also possible to install large volumes that cannot be obtained with tanks.

This is because although the diameter of the hose is small, by making it longer, you can increase the internal volume beyond imagination.

For example, if the inner diameter is 8 inches, the length is 10rrL, which is 3
004 or higher.

Additionally, both the suction and delivery hoses are connected to one end of the flexible hose, and the other end of the hose is simply connected to a thin, easily extendable air tube, making it easier to connect the thicker suction and delivery hoses. Simply install the connecting side in a convenient location for drawers, and the air piping side can be pushed deep into confined spaces.

With this configuration, the device of the present invention makes it more convenient to install the hose, and achieves the great effect that a large-volume vacuum tank can be installed simply and easily in a narrow dead space.

In addition to this, the fact that the vacuum tank is a hose means that
In cases where conventional hoses cannot be transported to the installation site, such as when installing a vacuum tank on a fishing boat as mentioned earlier, flexible hoses can be used to transport small batches. It can be carried in without expanding it, making the carrying process considerably simpler and easier, and it can be installed in almost any location.

Furthermore, even if the bent part of the hose becomes clogged with solid matter, the hose itself can be deformed. It has a number of benefits that are extremely important for this type of device, such as being able to easily pull it out from the installation location by removing it, and making it possible to unclog the vacuum tank extremely smoothly.
