Description

The utility model relates to elastic containers (soft) tanks designed for storage and transportation of liquids, including petroleum products, and can be used in all sectors of the economy.

Various liquid tanks are known in the art.

For example, a fluid reservoir (patent RU 2134225) is known, containing an elastic closed shell consisting of upper and lower panels, on the top of which there is a manhole cover with a filler neck and a device inside the shell for increasing the drainage completeness with flow openings, characterized the fact that the device for completeness of discharge is made in the form of a spatial rigid structure, fixed around the perimeter of the manhole and having a diametrical rigid vertical partition. Also known is a mobile elastic tank for petroleum products (patent RU 2304553), containing a pallet on which a closed shell consisting of a fuel-resistant, light-shielding and power layers, and having a drain and filler neck, characterized in that the fuel-resistant layer is placed on the upper surface, is fixed made of two layers of polymer material with a thickness of 80-150 microns with a mass of not more than 0.3 kg / m2, a breaking load of at least 200 N, a brittle temperature of at least minus 50 ° C, and a maximum temperature of the stored oil deposit kta not higher than 70 ° C, permeability not more than 10 g / m2 per day, the light-protective layer is made of an electrically conductive fathom-filled polyethylene film with a thickness of 80-150 μm, the power layer is placed on the outside of the tank and is made of one or two layers of folded polypropylene fabric with a surface density 200 ± 20 g / m2 and the number of threads per 10 cm of fabric on the warp and weft 54 ± 2 and 50 ± 2, respectively, while the inside of the pallet is made of a material identical to the material of the fuel-resistant layer and represents a closed airtight cavity for filling with air or another agent, and the outer one is made of material identical to the material of the power layer, the side walls of the outer part of the pallet have a height equal to at least 0.7 of the height of the filled elastic tank and are located relative to the bottom at an angle of 65-75 °.

Also known is a soft reservoir for liquids (patent SU 1559617), comprising a closed shell with ends, a coating and a bottom, drainage nozzles located at one of the ends, a heating device with a unit for folding the tank into a roll made in the form of flexible elements, characterized in that , in order to reduce the time of liquid unloading while reducing labor costs, it is equipped with an elastic partition located above the bottom with the formation of a cavity for the coolant, flexible elements are made of material with eff including shape memory have different lengths and mounted in the partition, wherein the initial portion of each of the flexible elements located at the same distance from the end face, located opposite slivonalivnym nozzles. All known solutions of soft tanks have disadvantages associated with the need to use them in open spaces. They occupy areas (plots of land) that are not always available and renting the area of such plots is often expensive. In addition, in the event of an active external impact or a man-made accident when the tank is damaged, oil products spill onto the ground, violating the local environment.

Known soft liners in the barn for storing oil (VASN) from oil-resistant material (http://www.specposhiv.com/vkladysh_myagkii-jz_neftestoikogo_materiala_v_ambar_dlya_ne fti_vasn.html).

A soft liner of oil-resistant material in the BACN oil barn is used to store oil, oil products and aggressive liquid waste at an ambient temperature of -40 ° C to + 40 ° C.

A soft liner in a barn for storing oil from oil-resistant material prevents the penetration of oil, oil products and aggressive liquid waste into the soil during their temporary storage in a soil barn.

A soft liner made of oil-resistant material is an environmentally friendly material and helps protect the environment from pollution by toxic aggressive waste products, prevents the discharge of waste oil products into the soil, into water bodies and sewer systems. A soft BACN oil barn liner is made from a gas-resistant environmentally friendly polymer-fabric material.

Along the perimeter, the liner has eyelets (holes) for attaching to the slopes of the barn debris.

The disadvantage of the liner is the need for its use in open spaces only the area of the oil storage. In addition, the liner is open to external influences, which increases the risk of fire of petroleum products. The closest solution is the Flexible Container Tanks “Flexitank Container” (see http://www.neftetank.ru/products-gibkie/konteynernie-fleksitanki-2.html). Flexitank is a polymeric elastic plug-in tank of a pillow shape. The flexitank shell is made of several layers of polymer high-barrier films hermetically connected to the outlets of the drain and bulk fittings and the air pipe placed inside the power shell made of thick polypropylene fabric of increased strength. Drain-and-fill fittings are made of chemically resistant reinforced polymers and include a branch, ball valve, pressure-suction hose and quick-assembled “camlock” coupling. The diameter of the drain and bulk fittings is 2 ”or 3” (50-72 mm).

The air nozzle is designed to release air that enters the interior of the sealed enclosure during filling.

The supporting boards of the doorway are designed to fix the flexitank inside the container with the door half open during filling (discharge).

The disadvantage of the solution is the need to use supporting boards of the doorway to fix the flexitank inside the container with the door half open during filling (discharge). Also, when the container walls are not strong enough, for example, when using box garages, where a thin sheet of metal is used as side walls, the container walls may not withstand the burst pressure of the tank.

The purpose of the claimed utility model is to eliminate the shortcomings of known reservoirs and to create such a design that would be able to be placed inside any type of container without the need for additional support of the doorway to fix the tank inside the container with the door half open during filling (discharge).

The technical result of the claimed utility model is a soft liner device that allows you to quickly and reliably place the liner inside garages, cellars, caravan containers and railway wagons of container type, without destroying their walls and without the need to erect additional doorway supports to fix the liner inside the container with open half of the door during loading (discharge).

The specified technical result is achieved due to the fact that the container is a soft tank containing a container of a polymer bottom and walls, a drain and filler valve, an air pipe, characterized in that at least one air chamber is fixed along the perimeter of the tank.

Brief Description of the Drawings

Figure 1 shows the constructive structure of a tank placed in a container (a is a top view, 6 is a sectional side view), where 1 is a container, 2 is a soft tank, 3 is a drain pipe, 4 is an air pipe, 5 is an air chamber .

Soft tanks can be made of a single-layer polymer material (depending on the purpose) using a double seam. They have a pillow shape, can be placed on an unprepared surface.

The principle of manufacture of the tank - individual sheets of polymer material are welded together to form a rectangular container. When filling, it takes the form of a pillow. All seams are double.

Air chambers can be fixed to the shell of the tank, for example, by gluing.

The process of deployment of the tank may be, for example, the following.

As a rule, soft tanks are rolled up during transportation. This allows you to place the roll in any tank, whether it is a warehouse, garage or container of a railway car (see Figure 1).

After placing the roll of the tank (2) in the container (1), it is quickly and simply deployed by blowing the air chambers (5) with an electric pump, which stretch the shell of the tank, giving it the desired shape, ready for filling with liquid products.

Since there is no load (even minimal) on the tank in any case, the self-weight of the tank, which as a rule does not exceed 150-200 kg, even for large tanks, is maintained by inflated air chambers (5).

After filling the tank (2), it is kept from bursting by the pressure of the chambers (5), enveloping it around the perimeter.

When placing the tank (2) inside the container (1), filling and draining of the product from the tank is possible through the filler pipe (3).

The discharge and discharge pipe (3) can be made of reinforced chemically resistant polymers and include a branch, ball valve, pressure-suction hose and quick-assembled “camlock” coupling. The air pipe (4) is designed to release air that enters the interior of the sealed enclosure during filling.

If it is necessary for service personnel to move inside the container (1) to insert the drain hose into the pipe (3) and open the air pipe (4), people can easily move in the area under, above or between the air chambers (5) (if there are more than one ) This eliminates the need for any doorways or the need to erect additional supports for the doorway to fix the tank inside the container with the door half open during filling (discharge).

Thanks to the inflated air chambers (5), the soft reservoir is quickly and reliably located inside garages, cellars, caravan containers and railway wagons of container type, without destroying their walls.
