Transport trough for transporting and heating of chemical substances

A transport trough for transporting and heating of chemical substances, which comprises:

• a flat bottom comprising an upper surface and a lower surface,
• a circumferential frame, which together with the flat bottom forms a trough-shaped cavity for receiving the chemical substances, wherein the circumferential frame is connected to the flat bottom in a non-destructively detachable manner,
• wherein the circumferential frame comprises a plurality of flat frame sections and a plurality of corner sections that are arranged such that two adjacent flat frame sections are connected to each other by one corner section of the plurality of corner sections, said circumferential frame further comprising a plurality of flanges for attaching the flat bottom to the circumferential frame,
• wherein at least one flange of the plurality of flanges is formed at least in part by a lower portion of a flat frame section of the plurality of flat frame sections and/or by a lower portion of a corner section of the plurality of corner sections and said at least one flange having an upper surface and a lower surface and is arranged either (a) at a location of one corner section of the plurality of corner sections such that said at least one flange extends outwardly away from a center of the transport trough and said one corner section is set back inwards towards the center of the transport trough relative to said at least one flange, said at least one flange defining a portion of an outer periphery of the transport trough at the location of said one corner section or (b) along at least part of a length of the flat frame section such that said at least one flange extends inwardly towards the center of the transport trough and the upper surface of said at least one flange supports the lower surface of the flat bottom or (c) along at least part of a length of the flat frame section such that said at least one flange extends outwardly away from a center of the transport trough and said one frame section is set back inwards towards the center of the transport trough relative to said at least one flange.
