Description

Technical Field

[0001] This utility model relates to the field of polyacrylonitrile technology, specifically to a distillation kettle for polyacrylonitrile production with a stirring function. Background Technology

[0002] Polyacrylonitrile is a polymer compound obtained by free radical polymerization of acrylonitrile monomer. It appears as a white or slightly yellowish opaque powder with a density of 1.184 g / cm³. 3 Polyacrylonitrile (PAC) is insoluble in most organic and inorganic solvents, with a melting point of 317℃. It exhibits stable chemical properties and resistance to chemical reagents, particularly inorganic acids, bleaching powder, hydrogen peroxide, and general organic reagents. While PAC is insoluble in most organic and inorganic solvents, it is soluble in polar organic solvents such as dimethylformamide, dimethyl sulfoxide, sulfolane, and ethyl nitrate, as well as concentrated aqueous solutions of inorganic salts such as thiocyanate, perchlorate, zinc chloride, and lithium bromide, and special solvents such as concentrated nitric acid. Furthermore, PAC exhibits good resistance to chemical reagents, especially inorganic acids, bleaching powder, hydrogen peroxide, and general organic reagents. However, the production of PAC requires the use of a distillation vessel. Currently, commercially available distillation vessels have relatively simple structures, making them inconvenient for lifting and transportation. Therefore, a distillation vessel with a stirring function for PAC production is proposed. Utility Model Content

There is a lifting ring 8. Two clamps 9 are fixedly installed on the outside of the vessel body 1. The vertical plate 7 is fastened inside the clamps 9. Both ends of the clamps 9 are integrally machined with limit protrusions 10. The outside of the vessel body 1 is provided with a support structure. When the vessel body 1 is hoisted and transported, the vertical plate 7 is connected to the outside of the vessel body 1 through the mounting base 6. The vertical plate 7 is separated from the clamps 9. Then, the lifting ring 8 at one end of the vertical plate 7 is connected to the external hook to hoist the vessel body 1. After hoisting, the vessel body 1 is installed. Then, the raw materials are poured into the vessel body 1. The motor 3 is started to drive the transmission rod 4 to rotate. Multiple stirring rods 5 are fixedly installed on the outside of the transmission rod 4. The stirring rods 5 will rotate with the transmission rod 4 to stir the raw materials inside the vessel body 1.

[0022] The supporting structure includes a first annular plate 11, which is fixedly installed on the outside of the vessel body 1. Multiple threaded rods 12 are threadedly connected to the inside of the first annular plate 11. Circular plates 13 are fixedly installed at both ends of the multiple threaded rods 12.
