Middle-sized bulk container

Abstract

The invention relates to a middle-sized bulk container, which is firm in welding points of a pipe of a peripheral framework and not easy to brake, and belongs to the technical field of a package container. The middle-sized bulk container is characterized by comprising a framework (1) and an internal barrel (2), wherein the internal barrel (2) is arranged inside the framework (1), the framework (1) is formed by welding a plurality of square pipes (3) which are distributed in transverse direction and longitudinal direction, the top surface of each square pipe (3) is provided with a groove (4), and two sides of each groove (4) are protruded to form a welding surface (5). The middle-sized bulk container is simple in manufacturing process and low in production cost; and moreover, the welding points of the pipes are firm, and the breaking phenomenon is not easy to happen.

Description

technical field [0001] The invention relates to a medium-sized bulk container. The welding points of the pipes on the outer frame of the container are firm and difficult to break, and belong to the technical field of packaging containers. Background technique [0002] Medium-sized bulk containers, because of their large capacity, safety and reliability, and small footprint, are suitable for sea, land, and air transportation. They have become one of the important liquid transportation tools in the chemical, food, and building materials industries. In terms of capacity and occupied space, an IBC occupies an area equivalent to four ordinary round drums, but can hold liquids that can only be contained in five ordinary round drums, greatly reducing transportation costs. Moreover, due to a series of safety measures in the design of the medium-sized bulk container itself, the medium-sized bulk container has higher safety, and has better anti-vibration, anti-drop and other character...

AI Technical Summary

Problems solved by technology

[0003] The peripheral frame of a traditional medium-sized bulk container is formed by welding several circular tubes after bending. Since the welding surface of the circular tubes is small, it is necessary to squeeze the welding points of the circular tubes to deform them and form local depressions. However, in There are many processes for pressing local depressions on the round tube, the manufacturing process is complicated, the production cost is high, and the round tube is easily damaged, thus affecting the quality of the intermediate bulk container

During the long-distance transportation of medium-sized bulk containers, due to the bumps, they will be subject to large vibrations, which will cause the accumulation of stress at the solder joints, and eventually cause the solder joints to fall off or the round tube to crack or even break
