[0001] This utility model belongs to the transportation industry and can be used to produce
a heavy-duty bag for shipping bulk goods with low volumetric density, such as bulk
construction materials, raw materials for the metallurgical industry, chemical products,
raw sugar, grain, coffee, and other food cargos.
[0002] Hence, there is a flexible container for transporting and storing bulk goods (Ukrainian
patent for invention No. 72054, published on 07/15/2003), which includes a receptacle
with an upper loading aperture, a lower unloading aperture, and a power frame. This
invention also comprises a locking device, a power grid with lifting loops and a bottom.
According to this well-known invention, a receptacle is arranged in a power grid and
coupled to it in the upper section by a detachable joint, which consists of sequentially
interconnected loops fixed on the receptacle and the power grid having the last group
of loops shorted by a cord tie. Moreover, the continuation of the loops fixed on the
receptacle is made as ribbons, placed obliquely to the threads of the base of the
receptacle. The power grid has a bottom with an opening and a rim element connected
to the unloading aperture of the receptacle, and the receptacle is equipped with sleeves
having tape loops and a system of valves. One of the sleeves is fixed on the loading
aperture of the receptacle.
[0003] In terms of technical nature, purpose, and achieved result, the most similar to the
claimed utility model is the Flexible Container "MK 14" (http://nttrans.net/ru/mk-14-10),
which includes a receptacle with an upper loading aperture, a lower unloading aperture,
and a power frame. This device also comprises a locking device, a power grid with
lifting loops and a bottom.
[0004] This well-known device shows such a drawback as a small volume (13 m
3), which makes it impossible to fill the whole useful space of the open wagon with
bulk cargo with a low volumetric density of 0.78 t/m3 and less due to its cylindrical
shape. This causes the loss of the useful space of the open wagon.
[0005] Thus, one cylindrical bag can hold up to 10 tons of light weight.
[0006] More specifically, one 13 m
3 sack can hold 10.14 tons of grain (with a volumetric density of 0.78 t/m
3).
[0007] The open wagon can hold 5 such bags. This means that a wagon, which can transport
up to 67 tons, carries only 50.7 tons.
[0008] In terms of logistics, this is economically unprofitable.
[0009] This utility model was primarily aimed at increasing the volume of the receptacle
and, as a consequence, increasing the payload volume of the wagon.
[0010] The set task is solved by providing the FLEXIBLE CONTAINER FOR TRANSPORTING LIGHT
BULK GOODS with a receptacle with an upper loading aperture, a lower unloading aperture,
and a power frame. According to the utility model, a receptacle is shaped as a rectangular
parallelepiped with a volume exceeding 13 m
3. It has a loading aperture on the upper base and an unloading valve on the bottom.
It comprises four soft perforated partitions located inside this container, equipped
with a sling assembly that connects to each other at the bottom of the bag. The load
loops of the sling assembly have a detachable coupling with the flexible container
at its upper base, as well as an additional load distribution sling, which in turn
has a coupling with the container at its upper base, and sling straps located on the
outer perimeter of the container.
[0011] This utility model addresses the problem of increasing the volume of the container
and, consequently, the payload volume of the wagon by creating a bag of up to 17 m
3, which has the shape of a rectangular parallelepiped that will fill the entire payload
volume of the open wagon. Thus, it becomes economically advantageous to transport
light bulk goods in the open wagon. When this target is achieved, 66.3 tons of grain
will be transported in the open wagon (17 m
3 x 0.78 t/m
3 = 66.3 tons), which is basically 16 tons more than the known cylindrical sacks in
the open wagon.
[0012] This is further enhanced by the fact that the proposed container has the shape of
a rectangular parallelepiped and a volume greater than 13 m
3 and is equipped with four perforated partitions.
[0013] The utility model can be illustrated by the following drawings:, wherein
Fig. 1 shows a general view and
Fig. 2 shows a sling assembly separately.
[0014] This multipurpose container has such basic components (see Fig. 1 and Fig. 2): Flexible
container (1) is shaped as a rectangular parallelepiped with a volume exceeding 13
m
3. It has a loading aperture (2) on the upper base and an unloading valve (3) on the
bottom. It comprises four soft perforated partitions (4) located inside this container,
equipped with a sling assembly (5) that connects to each other at the bottom of the
bag (6). The load loops (7) of the sling assembly have a detachable coupling (8) with
the flexible container at its upper base, as well as an additional load distribution
sling (9), which in turn has a coupling (10) with the container at its upper base,
and the sling straps (11) located on the outer perimeter of the container.
[0015] This device is operated as follows. Flexible container for transporting and storing
bulk goods is used according to the well-known pattern: loading, transportation to
the consumer, and unloading. Before loading the bulk check cargo whether the unloading
valve (3) is closed. Then the container is lifted, suspended by the main slings (11),
and connected to the hopper feeding bulk cargo. Then, the lower unloading valve (3)
is released, through which the container's bulk cargo is discharged.
[0016] Hence, the utility model attains the objective of increasing the volume of the receptacle
and, as a consequence, increasing the payload volume of the wagon.
