Description

  The present invention relates to a flexible container vehicle used for conveying powder and a method for transporting powder using the flexible container vehicle.

In general, when transporting and storing a large amount of industrial raw materials, food materials, livestock feed, agricultural fertilizers and synthetic resin pellets, etc., the weight is lighter than the load, and the flexibility is high. Foldable flexible containers are widely used. Like conventional metal containers, such flexible containers include columnar or box-type vertical and horizontal types, and both types are folded small when returned to the carrier bed of the transport vehicle. It can be stored in the vacant space, and can be transported on the return path by loading other packages in the vacant space. In addition, the handling of flexible containers is basically possible for one person by using a crane, forklift or jack for both vertical and horizontal types. In addition, it has realized efficiency and labor saving in the vehicle, and also realized energy saving in terms of transportation.
On the other hand, many of the powders that fill the flexible container are lightweight, so an extra space is created at the time of charging, and it cannot be packed densely. However, there was a problem that the powder particles were clogged in the middle, and the powder particles could not be discharged well. In order to cope with such a problem, several inventions and devices have been disclosed.

For example, in Patent Document 1, the inventor of the present application named “flexible container and flexible container vehicle and ship equipped with the same” from a double structure of an inner bag having airtightness and an outer bag having pressure resistance. Therefore, an invention relating to a flexible container provided with a blowing facility for blowing air inside the flexible container, a flexible container vehicle equipped with the flexible container, and a ship is disclosed.
In the invention disclosed in this Patent Document 1, the flexible container includes a seamless trunk portion, and an input port and a discharge port installed at both opening ends of the trunk portion. It has a shape with a small diameter toward the open end. Further, the trunk portion includes an inner bag having airtightness and an outer bag having higher pressure strength than the inner bag, and further, a blower pipe having a plurality of air supply holes formed in the inner bottom portion of the trunk portion. It is installed so that air can be taken in and out of the flexible container through the air port.

When filling the powder, with the discharge port and the air port closed, the powder is charged from the input port, and then the air port is opened and compressed air is sent from the blower pipe. Stir.
Also, when discharging the powder, with the inlet closed, open the air opening and send compressed air into the flexible container, while blowing up the filled powder to make it flowable Since the powder is discharged from the discharge port, the discharge operation can be easily performed without clogging the powder. Also, by installing a pillow bag that can be supplied from the outside between the inner bag and the outer bag, and supplying air to this pillow bag to form an angle of repose on the inner wall of the inner bag and generating vibration in the tapered portion It is also possible to discharge the powder more efficiently.
Furthermore, since the inner bag is highly airtight, it is possible to prevent the occurrence of contamination by preventing leakage of the filling material, and the outer bag is seamless and has high pressure resistance, so it is a flexible container even under high pressure. Prevents breakage of the body and leakage of the filler. And since only the inner bag can be exchanged according to the filling and the same outer bag can be used repeatedly, cleaning work inside the flexible container becomes unnecessary and work efficiency can be improved. In addition, the flexible container body is not equipped with a metal mirror, so it can be carried, and when returning, the volume of the flexible container body can be compressed to one-tenth that of powder filling, so transport efficiency is good. It has become a thing.

Further, Patent Document 2 discloses an invention relating to a flexible container for flowing a granular material by sending air into the flexible container under the name of “a flexible container for granular powder and its utilization system” and a system associated therewith. ing.

In addition, a discharge cylinder provided with a discharge cylinder valve is installed on the side plate. In addition, each of the input cylinder, the discharge cylinder and the side plate is provided with a pressure air nozzle having a pressure air pipe valve, a transport pipe nozzle having a transport pipe valve, and a fluid air nozzle having a fluid air pipe valve. ing.
And, when filling the granular material, it is possible to deaerate the inside of the flexible container by sending the pressurized air from the nozzle for pressurized air, so that the granular material is closely packed without generating an extra space Can be done. In addition, when discharging the granular material, the upper side inside the flexible container body is sent by feeding the flowing air from the fluid air nozzle into the fluidizing air chamber formed in the lower space inside the flexible container body by the dispersion plate. Since the powder particles filled in the container are fluidized so as to easily flow out like a liquid, the powder particles can be easily discharged without causing clogging.
Furthermore, since the flexible container main body can be gathered compactly at the time of return, it becomes possible to greatly open the space of the carrier bed of the transport vehicle.

Patent Document 3 discloses an invention relating to a flexible container having an air chamber for storing air inside a flexible container having a double structure of an inner bag and an outer bag under the name of “powder carrying bag”. ing.
The invention disclosed in Patent Document 3 includes an air-permeable inner bag, an air-tight outer bag, and an air slide device attached to the bottom of the inner bag. It is fixed to.
Therefore, when air is fed from the air slide device, the air passes through the inner bag and the outer bag expands, and an air chamber is formed between the inner bag and the outer bag. The inner bag is fixed so that the lower side surface forms a V shape when the air chamber is formed. Therefore, when discharging the granular material, the granular material is in the center of the V shape. It is possible to discharge smoothly without gathering together and causing clogging of powder particles. Furthermore, since only one air tube is required to feed air into the inner bag, the structure of the entire powder carrying bag is very simple.
