Description

 The invention relates to the field of transportation and storage of bulk cargo, such as bulk construction materials, raw materials for the metallurgical industry, chemical products, raw sugar, grain, coffee and other food cargoes.

 The closest to the claimed invention is a soft container for transporting and storing bulk cargo (RU 2132296 C1, M.L. 7 B 65 D 88/22, 06/27/1999).

 The known 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 grid sewn onto the outer surface of the container. A soft container is suspended on a crane hook by loops that are a continuation of the tape power frame. The loading opening of such a soft container is very large and equal to the diameter of the container itself, which ensures ease of loading, but does not allow for the tightness of the upper part of the container.

 The unloading hole due to the quick disconnect connection of the bottom with the tank provides instant unloading of the entire mass of the cargo. But in this case, unloading into the hatch of a ship, wagon or other vehicle is not provided. However, it is not possible to ensure sufficient tightness of the lower part of the soft container, which is very important for a number of cargoes. In addition, when loading and unloading, atomization of bulk cargo is not excluded, which negatively affects working conditions and the environment. The design of the known soft container reduces the convenience of its operation, especially when loading into narrow hatches of vehicles or storages.

 The technical result of the claimed invention is to improve ease of use by providing a tight load from production pipelines and unloading the container into the narrow hatches of vehicles or storages while ensuring the required working conditions and protecting the environment from pollution.

 The specified technical result is achieved in that in a soft container for transportation and storage of bulk cargo containing a container with an upper loading hole and a lower discharge opening, a power grid with lifting loops, a bottom and a locking device, including tape loops with a metal ring at one end for pinching, a stud for checking and locking ribbons to protect against spontaneous stripping, the container is placed in the power grid and connected to it in the upper part by a detachable connection consisting of loops connected in series, mounted on the container and on the power grid with the closure of the last group of loops with a cord, and the extensions of the loops mounted on the container are made in the form of tapes placed obliquely to the warp and weft fabric threads, in the power grid there is a bottom with an opening and a rim element, combined with the discharge opening of the container, while the tank is equipped with sleeves with tape loops for pinch and a valve system, one of the sleeve in mounted at the top on the loading opening of the tank to ensure the loading process without spraying bulk cargo and sealing the upper part of the container during transportation and storage of bulk cargo, and the other sleeve has a locking device and is mounted on the lower discharge opening of the tank with the ability to refuel its output section when unloading in hatches vehicles and storages and eliminating the spraying of bulk cargo into the environment, the valve system has a stop device and is mounted on the rim lemente bottom power grid holes for fixing the sleeve in the folded state, hardened at the discharge opening of the container.

 This design of the claimed soft container allows you to connect the sleeve fixed to the loading hole to the loading hopper (or to the production pipeline) with maximum convenience, in a short time and with the complete exception of spraying during the loading process, it allows you to reliably close the sleeve through a belt loop for pinching, which provides tightness of the upper part of the soft container from exposure to atmospheric moisture during prolonged transportation or storage.

 The design of the (lower) sleeve fixed to the discharge opening, its geometric construction, the system of valves and locking devices allow filling the sleeve directly into the hatch of a railway carriage, ship, tank truck or storage, etc., which ensures quick unloading of a soft container and eliminates the spraying of loose the product into the environment, since upon delivery to the place of unloading, sequential actions are taken to suspend a soft container onto the crane hook, and to hold valves, I hold and their rolled zachekovanny (lower) sleeve, the sleeve then refilling a vehicle hatch or storage, and only then popping your pinched sleeve, which causes the unloading of the soft container.

 The design of the soft container in the form of independent elements - the container and the power grid, interconnected by a detachable connection from sequentially closed groups of loops belonging to both the tank and the grid, allows you to quickly unmount the soft container, repair damage and re-assemble 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.

 The fastening (stripe) of the tapes, from which the detachable connection loops are formed, onto the fabric of the container with an inclination towards the direction of the warp and weft causes a more even distribution of the load on the fabric of the tank due to the loading of both warp and weft threads.

 The fastening of the valve system on the pole collar in the opening of the bottom of the power grid provides the convenience of folding rolled up (folded) and fixing the sleeve fixed to the discharge hole.

 The invention is illustrated by drawings, where in Fig.1 shows a soft container, General view; figure 2 is the same, a view in profile; FIG. 3 is a view A of FIG. 2; figure 4 - soft container during loading from the production line (pipeline); figure 5 - loaded soft container with a clamped sleeve, mounted on the loading hole of the container; figure 6 - loaded soft container before unloading in the hatch of a railway carriage; Fig.7 - soft container during unloading in the hatch of the tanker; on Fig - soft container during unloading in the hold of the ship.

 A soft container for transportation and storage of bulk cargo (figure 2) contains a container 1 with an upper loading hole 2 and a lower discharge opening 3, a power grid 4 with lifting loops 5 and a bottom 6 with an opening 7 aligned with the discharge opening 3, and having a rim element 8. The container is placed in the power grid 4 and connected to it in the upper part by means of a detachable connection 9, consisting of loops 10 of the tank 1 and loops 11 of the power grid 4 connected in series, the last group of loops 10 and 11 being closed by a cord howl complication 12. Loops 10 are formed 13, ribbons, strength (sewn) to fabric 14 of the container 1 obliquely to the direction of the warp and weft fabric. At the loading opening of the container 1, a (upper) sleeve 15 is fixed with an output end portion 16 and a tape loop 17 (FIG. 1) for pinching. At the discharge opening of the container 1, a (lower) sleeve 18 is fixed with an output end portion 19 and with a belt loop 20 for pinch clamping, which is notched by a pin 21. On the rim element 8 of the opening of the bottom of the power grid, a valve system 22 is installed, which has a pin 23 for valve check. Sleeve 15 provides a loading process without spraying bulk cargo and sealing the upper part of the soft container during transportation and storage of bulk cargo. The sleeve 18 provides the ability to refuel its output end section when unloading in the hatches of vehicles or storage and eliminating the dispersion of bulk cargo into the environment.

 The soft container for transporting and storing bulk cargo works according to well-known technology.

 Figure 4 shows a soft container, (upper) sleeve 15 of which the output end section 16 is connected to the factory line. Through the sleeve 15, the container is filled with bulk material.

 The upper sleeve 15 of the filled soft container (figure 5) is pinched by a tape loop 17, creating a sufficiently tight container.

 The loaded soft container, delivered to the place of unloading, is suspended by the lifting loops with a crane above the hatch of the vehicle (Fig. 6). In this position, the valve system 22 is detached, the (lower unloading) sleeve 18 is released and hangs freely above the hatch of the vehicle. The sleeve 18 is clamped by a tape loop 20 and is riveted with a pin 21.

 Further (Fig. 7), the soft container is lowered so that the output end portion 19 of the sleeve 18 enters the hatch of the vehicle, the pin 21 is stripped, the tape loop 20 releases the clamped area of the (discharge) sleeve 18, and the bulk material is poured from the soft container into the vehicle .

 The same process is shown in Fig. 8 for the case of unloading the container into the hold of the ship.

The implementation of this invention provides:
- the ability to load soft containers directly from production pipelines and silos;
- the possibility of unloading into narrow hatches of vehicles;
- tightness of the container in the areas of the upper (loading) and lower (discharge) holes;
- increase the resource and service life of soft containers;
- convenience of replacing damaged parts of soft containers;
- increase maintainability of soft containers;
- simplification of operation of soft containers;
- the elimination of environmental pollution by spraying bulk materials during loading and unloading.
