Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chlorinated paraffin storage devices, specifically, it relates to a chlorinated paraffin storage device. Background Technology
[0002] Chlorinated paraffin, as an important chemical raw material, is widely used in plasticizers, flame retardants, and lubricant additives. Due to its molecular structure, chlorinated paraffin is extremely sensitive to temperature during storage: high temperatures easily lead to decomposition and deterioration, while low temperatures easily cause crystallization and precipitation, severely affecting product performance. Furthermore, chlorinated paraffin is highly corrosive, and long-term storage can easily erode the inner walls of containers, leading to leakage risks. Simultaneously, the material is prone to stratification when left stagnant, resulting in uneven composition and further reducing product quality. Currently, the industry generally uses conventional storage tanks for chlorinated paraffin storage, which has significant technical shortcomings: Firstly, temperature control methods are limited, relying heavily on external environmental regulation or simple heating / cooling devices, making precise constant temperature control difficult, and temperature fluctuations easily lead to material performance degradation; secondly, existing stirring devices are mostly conventional paddle structures, which easily create unidirectional material flow during stirring, making it difficult to eliminate local temperature differences and stratification, and also resulting in high stirring resistance and energy consumption. Utility Model Content
