Embodiment Construction

[0017] As used herein, the term "profile" is interchangeable with "tube" (or duct) (ie: an elongated object with an open cross-section). "Open" means any one or more geometric shapes. In general, the cross-section of the particularly preferred material, or at least a part of said cross-section, is rectangular or substantially rectangular, but it may also be round or elliptical. Said open cross-section may be formed by one or several of the aforementioned geometries.

[0018] By "structured wall" is meant a wall constructed by helically wound tubing, thereby including non-solid walls which are lighter than solid walls but are still equally strong.

[0019] "Lightweight" as used with the walls of the container means that the structured walls are formed from tubes or profiles with an open cross-section.

[0020] According to the invention, a cylindrical light-walled structure is formed from a tube comprising a coextruded material of the aforementioned type by helically winding ...

Abstract

Container for dry powders, granules, pellets, gas and other ignitable substances and method of producing the same. The container comprises a wall (11-13) formed by a spirally wound profile having an open cross-section, wherein adjacent windings of the profile are attached to each other. According to the invention, the profile comprises a first thermoplastic layer forming the inner surface (11) of the profile and a second thermoplastic layer (12) placed about the first thermoplastic layer and forming the outer surface of the profile, said second layer being antistatic. The present containers have good mechanical strength properties and accumulation of electric charges inside the container can be efficiently avoided. The container can be used, e.g., as a drier for material / powder / pellets.

Description

technical field [0001] The invention relates to a container according to the preamble of claim 1 for storing dry powders, granules, granules, gases and other flammable substances. [0002] Such containers generally comprise a cylindrical wall with end caps at opposite ends of the wall, the wall and end caps defining an enclosed space. [0003] The invention also relates to a method of producing a container according to the preamble of claim 10 . Background technique [0004] Large containers in the form of tanks and silos, typically used for long-term or intermediate storage of bulk materials such as dry powders, fines and granules. They can also be used to store liquids and gases. Typically, the tanks and silos have a volume from 100 to 5000 hectoliters or even more. [0005] In some industrial processes, memory cells of processing equipment are at risk of generating static charges. As such, the electrostatic charge will stick the particulate matter to the walls of the ...
