Description

The proposed utility model refers to the means of transport and road-building equipment and is intended for the transportation (storage) of solid and viscous oil products (oil bitumen, tar, oil mastics, paraffins, etc.).

A characteristic feature of solid and viscous petroleum products used for road and construction works is that they are packed by filling in a liquid (hot) form in a container, and storage and transportation - in a solid or viscous (softened) form, after cooling in a container. ...

From the prior art, various containers are widely known for storing and transporting solid and viscous petroleum products (bitumen, mastics, etc.) to the place of use.

For example, a medium-tonnage container is known for storing and transporting solid and viscous petroleum products, characterized in that it includes a hollow vertical shell made of multilayer cardboard, closed in a horizontal cross section and open throughout this section from the upper and lower horizontal ends, a pallet, a lid with a loading opening, vertical racks for holding the shell, fixed between the pallet and the lid, while the pallet has a metal bottom with vertical sides 30-100 mm high along the entire perimeter, the vertical shell is placed on the metal bottom, adjacent to the sides from their inner side , the junction points are treated with a heat-resistant sealing compound, at least one plate is installed from the inside of the shell at the level of the bottom sides, rigidly fastened to the shell and bottom by means of self-tapping screws twisted into the outer surface of the bottom sides, and on the inner surface of the shell and the upper horizon The flax surface of the metal bottom, bounded by the shell, was coated with an anti-adhesive coating (RF Patent No. 193707, published on 11.11.2019).

Also known is a medium-tonnage container for storing and transporting solid and viscous petroleum products, including a hollow vertical shell made of multilayer cardboard, closed in a horizontal cross section and open throughout this section from the upper and lower horizontal ends, a pallet, a lid with a loading opening, vertical racks for holding the shells, fixed between the pallet and the lid, and on the inner surface of the shell and the upper horizontal surface of the pallet, bounded by the shell, an anti-adhesive coating is applied (RF Patent No. 116843, published 10.06.2012).

The closest analogue of the patented solution is a Soft container for medium-tonnage transport containers, containing a shell having vertical walls and a bottom, the mentioned vertical walls consist of several layers of paper: the first being internal, the second being intermediate and the third being external, while said first layer is provided with an anti-adhesive coating from the inside, said second layer is made of sack paper, and the ends of said layers are glued together and with said bottom overlapping. The container is of a closed type with a certain geometric shape and additionally contains a lid. The mentioned cover is made of a three-layer corrugated cardboard and is equipped with four sides, separated from the cover plane by means of scoring so that when installed in a shipping container, said sides have the ability to bend (RF Patent No. 192029, published on 08/30/2019).

The general disadvantage of the known solutions is that their design limits the possibility of optimal / complete filling of the volume of a medium-tonnage container, based on the properties of hot liquid bitumen to expand its own volume, and cold to reduce its own volume. Filling the container to the upper edges of the flexible container often leads to leakage beyond the outer layers of the container, and after cooling, the medium-tonnage container leaves a free volume not filled with bitumen, which leads to an uneven distribution of the entire volume of bitumen solution in containers and an increase in the required number of containers for the transportation of bitumen.

The technical problem solved by the claimed utility model consists in the development of a medium-tonnage container for filling / packing, storage, transportation of bituminous materials with the possibility of maximum filling its volume with a molten solution of bituminous materials, while excluding its leakage beyond the outer layers of the container.

The task is solved due to the design of the medium-tonnage container, which makes it possible to fill bitumen up to the upper edge of the frame, the use of an anti-adhesive liner and a shell, the material of which excludes leakage of liquid bitumen through the outer layers of the container during the destruction of the liner materials.

The technical result of the patented utility model is the most complete filling of the medium-tonnage container without the use of additional mechanical means that are not part of the medium-tonnage container, and by eliminating leaks of liquid bitumen during the production process through the outer layer of the medium-tonnage container during the destruction of the container materials.

The claimed technical result is achieved due to the design of a medium-tonnage container for bituminous materials, including a frame made of solid materials connected to a pallet of solid materials along the contour, a shell made of a material based on cellulose with valves in the lower part inserted into the body, and a release liner made of polymeric materials , the upper part of which is attached to the upper edges of the shell, while the upper edges of the shell are located at the level of the upper edges of the frame.

In a particular case, the implementation of the frame is pulled together in the middle with a tape made of inelastic material.

In the particular case of implementation, a high-temperature sealing material is applied along the lower part of the shell.

In a particular case of implementation, the high-temperature sealing material is applied along the fold lines or along the seams of the valves of the lower part of the shell.

In a particular case, the implementation of the high-temperature sealing material is applied along the contour of the abutment of the bottom, made of a material based on cellulose and the shell body, or valves of the lower part of the shell.

In a particular case, the implementation of the frame is made of fiberboard or chipboard or OSB boards or boards of deciduous or boards of coniferous trees.

In the particular case of implementation, the pallet is made of fiberboard or chipboard or OSB boards or boards of deciduous or boards of coniferous trees.

In the particular case of the implementation of the release liner is made of polyolefin or polyamide or lavsan.

In the particular case of implementation, the shell is made of corrugated cardboard or multilayer paper.

In a particular case of implementation, the upper part of the shell, partially protruding beyond the upper edges of the frame, are flaps.

In the particular case of implementation, the insert is made with an open top.

In a particular case, the implementation of the insert is made with a cover in the upper part, including the filler neck.

In the particular case of the implementation of the insert is made with a cover of the upper part, including the filler hole.

In a particular case, the liner cover is made of the same material as the liner, or from a material based on cellulose or from chipboard or wood, and may have a release coating.

In a particular case, the implementation of the insert contains an anti-adhesive coating on the inner surface.

In a particular case, the implementation of the liner is made with a closed top and a filler neck or filler hole.

In a particular case, the implementation of the release coating is a material with a siliconized surface.

In the event of destruction of the polymer liner materials and the occurrence of leaks, liquid bitumen is absorbed by the fibers of the shell cellulose, based on its properties of hygroscopicity and heat resistance and does not fall behind the outer layers of the medium-tonnage container. These features ensure almost 100% filling of the container with bitumen after cooling and optimization of the bitumen transportation process, taking into account the elimination of leaks and deformation of the container shape.

Further, the solution is explained by references to the figures, which are shown:

FIG. 1 is a general view of a medium-tonnage container for bituminous materials in the version with an open liner.

FIG. 2 is a general view of a medium-tonnage container for bituminous materials in the version with a closed liner.

A medium-tonnage container for bituminous materials includes a frame 1 made of solid materials such as fiberboard, chipboard, OSB, hardwood or softwood boards. The frame is attached along a contour to a pallet made of hard materials such as fiberboard, chipboard, OSB, hardwood or softwood boards. For strength, the frame is pulled together at the side edges with an inelastic metal or polypropylene tape.

A shell 2 made of cellulose material, for example, corrugated board or multi-layer thick paper, is installed in the body. The shell can include four valves or a cover in the lower part, while along the fold lines or seams of the valves of the lower part of the shell or along the joints between the shell of the shell and the lower cover, a high-temperature sealing material is applied to seal the structure, for example, a high-temperature sealant, silicone, high-temperature adhesives. In addition, for additional sealing, the high-temperature sealing material can be applied along the contour of the abutment of the bottom made of cellulose-based material and the shell body, or the valves of the lower part of the shell.

The upper edges of the shell 2 are located at the level of the upper edges of the frame, these edges can be either a continuation of the side surfaces of the shell, or be four flaps.

Inside the shell 2, there is a release liner 3, which is a bag that repeats the shape of the shell. The liner is made of a polymer material that can withstand a temperature of about 200 ° C, for example, polyolefin, polyamide, lavsan. The upper part of the liner 3 is fixed on the upper edges of the shell 2 by bending the liner material onto the outer surface of the upper part of the shell or by stitching the liner material with the upper part of the shell by fastening with metal staples. The liner can be made with an open top (Fig. 1), and there are also versions of the liner with a closed top or with a removable top cover. In this case, on the closed upper surface or on the cover 4 of the liner, a filler hole 5 is provided (this option is shown in Fig. 2), or a filler neck for pouring bitumen.

The utility model is implemented as follows.

A shell is inserted into the assembled frame with open top flaps or with the height of the side surfaces at the level of the upper part of the frame. A polymer liner is inserted into the shell, the upper part of which is attached / wrapped on the valves or the upper edges of the shell to prevent the liner from losing its shape when pouring liquid bitumen. Bitumen is poured to the required level - to the upper edges of the shell. In this case, the pressure of liquid bitumen presses on the upper valves or the upper edges of the shell from the inside, and the liner restrains the pressure from the outside. Thus, the structure of the container is stable when filled with bituminous material. Then the filled container is transported to the place of temporary storage / cooling. After lowering the bitumen temperature, the liner is removed from the upper valves or the edges of the shell, placed inside the medium-tonnage container. The upper valves of the shell are closed; in case of execution without valves, the shell of the shell is bent inside the medium-tonnage container to the level of the cooled bitumen. After that, the products are ready for transportation.
