Description

Technical field

The utility model relates to transport containers and can be used for storage and transportation of bulk cargoes, including aggressive, as well as unit-piece and liquid cargoes in specialized containers.

State of the art

When transporting goods using standard steel containers, the latter quite quickly fail due to corrosion. This problem is especially relevant when transporting chemically aggressive cargo.

One solution to this problem is the implementation of the container from a corrosion-resistant material, such as aluminum. However, such containers have a high cost and are difficult to manufacture.

The closest analogue of the claimed utility model is a container for transportation of bulk materials, disclosed in the publication of application for US patent US 2003089742, 05/15/2003. The container contains a steel steel frame and a body made of corrosion-resistant material placed inside the frame. In the places of contact between the body and the frame, holes are made in which bushings are installed with coupling bolts placed in them for connecting the elements.

The disadvantage of this design is the possibility of electrochemical corrosion of the frame due to its direct contact with the elements of the body, which reduces the life of the container.

Utility Model Disclosure

The objective of the claimed utility model is to increase the service life of the container.

The technical result of the utility model is to reduce the corrosive effects of aggressive environments (transported material or the environment) on the container elements.

The specified technical result is achieved due to the fact that the container contains a power frame made of structural material, placed in the body frame and housed in the body of the inner lining layer of corrosion-resistant material, the body is made of electrically insulating material, while the power frame, body and lining layer are placed with ensuring electrical insulation of the frame relative to the inner facing layer.

In addition, there are private options for implementing the utility model, according to which:

- the body is made of plywood sheets connected to the frame by means of fasteners;

- places of joining of sheets of body plywood are insulated with glue;

- body openings for fasteners are insulated with glue;

- the inner facing layer is made of sheet material connected to the body by means of double-sided adhesive tape;

- the inner facing layer is additionally connected to the body by means of self-tapping screws passing through the facing layer into the body, but not reaching the frame;

- the inner facing layer is made in the form of a coating applied to the body;

- the inner facing layer is made of a metal material, plastic or fabric;

- power frame (1) is made of steel.

Thanks to the use of the power frame, the body and the corrosion-resistant facing layer, corrosion of the walls and bottom of the container is reduced while maintaining its strength and load-bearing properties. In this application, in the body structure providing electrical insulation of the frame from the facing layer, electrochemical corrosion of the container elements is excluded.

Brief Description of the Drawings

The utility model is illustrated by drawings, where:

in FIG. 1 shows a General view of the claimed container;

in FIG. 2 schematically shows the conjugation of the container layers;

in FIG. 3 schematically shows a variant of joining sheets of the inner facing layer.

Utility Model Implementation

The claimed container contains a power frame (1) located in the frame of the body (2) of electrically insulating material and located in the body (2) of the inner facing layer (3) of corrosion-resistant material.

The power frame (1), as a rule, includes a rigid frame (4) in the form of a substantially rectangular parallelepiped with corner fittings (5) and reinforcing ribs (6) in the area of the walls and bottom. The frame is made of a structural material capable of absorbing power loads, for example, of steel.

The body (2) of the container is installed inside the frame (1) and is a container with a bottom and walls, ensuring the transfer of loads from the transported cargo to the frame. The body (2) is made of electrically insulating material. It is preferable to use sheet material, in particular plywood, with a thickness of about 10-20 mm. However, it is possible to use other materials that provide electrical insulation.

The body (2) is connected to the frame (1) by means of fasteners, in particular bolts (7) and screws (8). Moreover, these fasteners (7, 8) are recessed into the body material (2), and the holes in which the fasteners (7, 8) are located are insulated from above with glue (sealant) (9). When performing the body (2) from separate sheets, the places of their joint are also insulated with glue (not shown in the drawings).

The inner facing layer (3) is designed for direct contact with the material of the transported or stored cargo and is made of corrosion-resistant material. It is preferable to use a metal material, for example stainless steel, aluminum, etc. However, it is possible to use other materials, such as plastic, fabric, etc. The thickness of the facing layer (3) can be from 0.5 to 5 mm.

In one embodiment of the utility model, the inner lining layer (3) is made of sheet material (Fig. 2), which is connected to the body (2) by means of double-sided adhesive tape (10). As an example, a 3M VHB tape 1.1 mm thick can be used. In the places where the sheets of the inner facing layer (3) are joined, grooves are made passing into the body layer (2). Moreover, these grooves are filled with glue (11), which provides sealing of the facing layer (3) and its isolation from the body. In addition to joining with adhesive tape, self-tapping screws (12) can be used, which are screwed into the locations of the specified tape through the sheet of the facing layer (3) into the body (2), but do not reach the frame (1). Such a connection additionally strengthens the connection of the facing layer (3) with the body (2) and does not violate the joint tightness. Self-tapping screws (12) are made of a material that excludes corrosion between it and the sheet of the facing layer (3) or does not form an electrochemical pair with the facing layer of the material. For example, stainless steel or aluminum may be used.

In another embodiment, the inner facing layer (3) is made in the form of a coating applied to the body layer (2). In particular, plywood can be used, in which, as the last layer of “veneer”, an aluminum layer is applied, forming a facing layer (3).

The container may also include a top cover (13) and / or an end hatch (not shown) for loading and unloading bulk material.

The claimed design has the following advantages:

1. High strength.

2. Complete tightness.

3. Corrosion resistance provided by isolating the frame from the facing layer, eliminating the welding of body elements, as well as the rejection of end-to-end connecting elements.

The specified container can be successfully used for transportation of various types of goods, including aggressive ones, for example fertilizers, sulfur, hot briquetted iron, etc.
