Description

Technical Field

[0001] The utility model relates to the technical field of transport devices, in particular to a transport device used for the production of acrylonitrile raw materials. Background Art

[0002] Acrylonitrile is a colorless, volatile liquid with a pungent odor. It is insoluble in water but soluble in organic solvents such as alcohols, acetone and dimethylformamide. Acrylonitrile is an unsaturated hydrocarbon that can undergo addition and oxidation reactions. It can react with hydrogen at high temperatures to generate propylene and with oxygen to generate acrylic acid. It can also react with strong acids such as sulfuric acid and nitric acid to generate corresponding salts. In addition, its vapor can form an explosive mixture with air, which can easily cause combustion and emit toxic gases when exposed to open flames or high heat.

[0003] Acrylonitrile is a chemical raw material, mainly used in synthetic fiber, rubber industry and plastic industry. It can also be used as a raw material for coatings, paints and adhesives.

During use, when the storage tank 1 needs to be moved, the column 503 is pulled to the right. When the column 503 moves to the right, it drives the blocking block 505 to move to the right. When the blocking block 505 moves to the right, it drives the protrusion 506 to move in the limiting slide hole 502 and squeezes the spring 504 at the same time. When the blocking block 505 moves to the right to the rightmost end of the limiting slide hole 502, the column 503 is rotated. At this time, the column 503 is separated from the socket 206, and the protrusion 506 is rotated to the L-shaped end of the limiting slide hole 502.
