Problems solved by technology

This internal grounding can only eliminate the charge formed in the liquid due to friction in the liquid. In addition, the danger of this liquid container is that when storing and transporting corrosive liquids, the grounding parts will be affected by such liquids. damage, which makes the electrical ground fail

Abstract

A conductive protruding pieces (24) made of high density polyethylene containing a conductive carbon black component is integrated into a main body (22) of the plastic-made inner container (2). The protruding pieces form an electric connecting means between the inner surface and the outer surface of the inner of the inner container (2) and its thickness is correspondent with the wall of the inner container (2). Legs (29 and 30) and a leg frame (31) of a seat (16) supporting the inner container (2) is made of a metal or a conductive plastic whereby the transporting and storing container (1) is electrically earthed via the conductive protruding piece (24) and a permanent anti-electrostatic outer layer (21) of the multi-layered plastic-made inner container (2), an outer shell (13) and the seat (16).

Description

technical field [0001] The invention relates to a liquid storage and transportation container, which has a tray-type bottom frame made of metal or conductive plastic. An inner tank made of plastic is installed on the chassis, which has four side walls, an upper bottom and a lower bottom, the upper bottom has a liquid injection port that can be closed, and the lower bottom has a liquid injection valve. The drain or upper bottom has a closable drain and an outer casing surrounding the liner with bars made of metal or sheet steel. Background technique [0002] The plastic liner of this type of storage and transport container introduced in DE 196 05 890A1 has a permanent antistatic outer layer, which is used as an electrical ground together with the metal chassis, in order to avoid friction between the liner and the metal jacket during transportation. Discharge generated on the plastic liner. Therefore, this method must be used to avoid the disch...
