Description

The utility model relates to the field of transportation and storage of bulk cargo in flexible containers with a carrying capacity of 14 tons or more, such as bulk building materials, raw materials for the metallurgical industry, chemical industry products, food and other cargo.

The following solutions are known from the prior art.

Known soft container for transportation and storage of bulk cargo (RU 2132296 C1, publication date 27.06.1999). The container is made in the form of a container made of synthetic material, reinforced with a tape power frame, in the form of a power mesh, sewn onto the outer surface of the container. The soft container is hung on the hook of a crane by the loops, which are a continuation of the belt load-bearing frame. The loading opening of such a soft container is very large and equal to the diameter of the container itself, which ensures the convenience of loading, but does not allow ensuring the tightness of the upper part of the container. The unloading opening due to the quick-release connection of the bottom with the tank provides instant unloading of the entire mass of the load. But in this case, unloading into the hatch of a ship, wagon or other vehicle is not ensured. At the same time, it is not possible to ensure sufficient tightness of the lower part of the flexible container, which is very important for a number of goods. In addition, during loading and unloading, spraying of bulk cargo is not excluded, which negatively affects working conditions and the environment. The design of the known flexible container reduces the convenience of its operation, especially when loaded into narrow hatches of vehicles or storages.

Also known is a soft container for transportation and storage of bulk cargo (RU 2407688, publication date 12/27/2010), containing a power grid with lifting loops, an insert located in the grid with a loading sleeve in its upper part and an unloading sleeve in its bottom part, respectively, the upper and lower fastening frames, wherein the power mesh is connected to the insert through at least one fastening unit, which contains loop garters, part of which is fixed on the power mesh, and part - on the surface of the insert.

Also known is a soft container for transportation and storage of bulk cargo (RU 2188785, publication date 09/10/2002), containing a container with an upper loading opening and a lower unloading opening, a power grid with lifting loops, a bottom and a locking device. The capacity of the known soft container is placed in the power grid and connected to it in the upper part by means of a detachable connection. The latter consists of loops connected in series, fixed on the container and on the power grid with the closing of the last group of loops with a cord tie. Moreover, the continuation of the loops fixed on the container are made in the form of tapes placed obliquely to the direction of the warp and weft threads of the container fabric.

Also known is a soft container for storage and transportation of bulk cargo (RU 2540788 publication date 02/10/2015), containing an insert with an upper loading and lower unloading openings, a frame power grid with lifting loops formed by alternating rows of vertical tapes and horizontal annular tapes with the formation of an upper and bottom parts. The frame mesh is additionally provided with obliquely arranged and crossed tapes, each of which is rigidly connected to each row of horizontal annular tapes, starting from the top and ending with the bottom row. This design provides increased rigidity of the frame mesh, which holds the soft container itself, however, there is a risk of lateral fall when the filling height is exceeded, in addition, the manufacturing process of such a frame mesh is quite complicated, which is not economically feasible.

The closest analogue of the patented device is a soft container for storage and transportation of bulk cargo (RU 2412099, publication date 02/20/2011), containing a power grid with lifting loops, an insert located in the grid with a loading sleeve in its upper part and an unloading sleeve in its bottom part. respectively, the upper and lower mounting frames, while the power grid is connected through the mounting upper frame with the insert by means of attachment points.

A common disadvantage of the known devices is that when repacking a container with cargo, a complete or partial spontaneous unloading of the unloading unit occurs, which leads to loss of cargo in terms of quality or quantity.

The technical problem consists in increasing the unloading speed by preventing the bulk medium from getting stuck during unloading, while ensuring the safety of the cargo in the transport position and preventing spontaneous opening of the entire unloading device of the container.

The problem is solved by refining the well-known design of a valve assembly with two locking devices (one for each group of four valves).

The technical result of the patented utility model is to ensure the tightness and safety of the cargo in the transport position by preventing spontaneous opening of the container unloading device.

The specified technical result is achieved due to the design of a soft container for transportation and storage of bulk cargo, containing a load-bearing mesh with lifting loops, an insert located in the mesh with a loading sleeve in its upper part and an unloading sleeve in its bottom part, respectively, the upper and lower mounting frames, in the power grid has a bottom with a hole and a rim element aligned with the discharge opening of the tank, a system of eight valves is fixed on the rim element to fix the sleeve in the folded state, the liner is fixed on the discharge opening, the system of eight valves has two locking units, each of which includes metal round or oval rings on three flaps and a metal oval ring on the fourth flap, a locking pin and locking ribbons, each locking unit connects four valves by fixing three round rings on a metal oval ring and locking them with a pin with with a locking tape, with the first group of four valves closing the connection between the valves of the second group of four valves.

In a particular case of the implementation of the utility model, the power grid is connected to the insert through at least one fastening unit, which contains loop garters, part of which is fixed on the power grid, and part - on the surface of the insert.

One of the sleeves is fixed in the upper part of the loading device, which allows you to connect the sleeve fixed on the loading opening to the loading hopper (or to the production pipeline) with maximum convenience, in a short time and with the complete elimination of spraying during loading, allows you to securely close the sleeve by means of a tape loop for pinching, which ensures the tightness of the upper part of the soft container from the effects of atmospheric moisture during long-term transportation or storage. The eight valve system has two locking devices, each of which is connected by four valves, and the first group of four valves, connected by its locking device, closes the connection between the valves of the second group of four valves, fastened by its locking device. Such a valve system, in comparison with the existing inventions of a flexible container, ensures greater safety of the cargo due to the fact that the valves are more tight, since the connections between the second group of valves are closed by the first group of valves, and prevents spontaneous opening of the entire container unloading device, since the load from the cargo on the valve is distributed evenly, and not on the entire system of valves at once (as in the designs of well-known soft containers). In addition, the use of one of the rings at the ends of the valve (an oval ring) as a means of connecting the remaining rings in the knot increases the reliability of the valve locking assembly, since, unlike the ribbon usually used for this purpose in the locking knots, the ring is not subject to abrasion with time.

The design of the lower sleeve, fixed on the discharge opening, its geometric construction, the system of valves and locking devices make it possible to fill the sleeve directly into the hatch of a railway car, ship, tank truck or storage, etc., which ensures quick unloading of the flexible container and eliminates the spraying of bulk product the environment, since during delivery to the place of unloading, successive actions are performed to hang the flexible container on the crane hook, to uncheck the valves holding the rolled and buckled (lower) sleeve, then to fill the sleeve into the hatch of the vehicle or storage, and only after that the pinched sleeve is unchecked , which causes the unloading of the soft container.

The execution of the soft container in the form of independent elements - the liner and the power grid, interconnected by a detachable connection of series-closed groups of loops belonging to both the liner and the grid, allows you to quickly disassemble the soft container, eliminate damage and re-mount the soft container to continue operation, which allows you to turn a disposable container into a reusable one by replacing an element that can withstand only a single use with a new one.

Further, the solution refers to the figures, which show the following.

A soft container for transportation and storage of bulk cargo contains an insert 1 with an upper loading opening 2 and a lower unloading opening 3, a power grid 4 with lifting loops 5 and a bottom 6 with an opening 7 aligned with the unloading opening 3 and having a rim element 8.

The insert 1 is placed in the power grid 4 and is connected to it in the upper part by means of the attachment 9 located along the upper mounting frame of the power grid 4, in which each restrictive element (not shown in the drawing) is fixed on the insert 1 and put on the corresponding loop of the garter 10 preloaded inserts attached to this garter loop. Also, the liner additionally contains a fastening unit in its side and/or lower part, the specified unit also contains loop garters, the first part of which is connected to the liner, and the other part is fixed on the mounting frame of the power mesh, while the loops of the garters mounted on the liner are connected to loops of garters, reinforced on a power grid, tie elements. Said additional attachment point in the side and/or bottom part to prevent tearing of the liner material and tearing off of the garter loops also contains restrictive elements, each of which is fixed on the liner and put on the corresponding liner garter loop with an interference fit.

On the loading hole 2 of the liner 1 is fixed (upper) sleeve 11 with the outlet end section 12 and tape loop 13 for pinching. On the discharge opening 3 of the liner 1, the (lower) sleeve 14 is reinforced with an outlet end section 15 and with a tape loop 16 for pinching, which is secured with a pin. A system of valves 17 is fixed on the rim element 8 of the opening of the bottom of the power grid.

The valve system 17 out of eight valves is conditionally divided into two groups of four valves, each of which has its own locking unit, including metal round or oval rings 18, fixed at the ends of three valves, and one oval metal ring 19, pin 20 and locking tape 21. The system of eight valves has two locking units, each of which connects four valves, and the first group of four valves (22), connected by its locking unit, closes the connection between the valves of the second group of four valves (23), fastened by its locking unit. The second group of four valves 23 is connected by fixing three metal round rings 18, fixed at the ends of the three valves, on the oval ring 19, fixed on the fourth valve of the group. Each of the valves of the first group 22 is located between two valves from the second group in such a way as to overlap the edges of these two adjacent valves from the second group 23, while the locking of the valves of the first group is carried out similarly to the locking of the valves of the second group (Fig. 6, 7).

The sleeve 11 ensures the process of loading without spraying bulk cargo and sealing the upper part of the flexible container during transportation and storage of bulk cargo. The sleeve 14 provides the possibility of refueling its output end section during unloading into the hatches of vehicles or storage and avoiding the spraying of bulk cargo into the environment.

The flexible container for transportation and storage of bulk cargo works according to known technology.

The upper sleeve 11 of the container outlet end section 12 is connected to the hopper (or to the production pipeline). Through the sleeve 11, the container is filled with bulk material. Next, the upper sleeve 11 of the filled soft container is pinched with a tape loop 13, creating a sufficiently tight container (the process is shown in Fig. 2-5).

The loaded flexible container delivered to the place of unloading is suspended by lifting eyes by a crane above the hatch of the vehicle or receiving hopper. The sleeve 14 is pinched with a tape loop 16 and pinned with a pin 21 and additionally fixed by a valve system 17. In this position, the valve system 17 is pinned, the lower unloading sleeve 14 hangs freely above the vehicle hatch.

Next, the soft container is lowered so that the outlet end section 15 of the sleeve 14 falls into the hatch of the vehicle or the receiving hopper, the pin is disengaged, while the tape loop 16 releases the pinched zone of the (unloading) sleeve 14, and the bulk material is poured from the soft container into the vehicle or receiving bunker.

The implementation of this invention provides:

the possibility of loading soft containers directly from production pipelines and bunkers;

the possibility of unloading cargo in bulk on open and covered storage areas, as well as in narrow hatches of vehicles, as well as intermediate storage bins; - tightness of the container in the areas of the upper (loading) and lower (unloading) openings;
