Description

Technical Field

[0001] The invention relates to a mixed film cooling technology, in particular to an isolation agent stirring-immersing system and a control method for film cooling. Background Art

[0002] In the rubber processing, cooling of the mixed rubber sheet is a key step to prevent premature vulcanization of the rubber compound and improve the efficiency of subsequent processes. At present, the cooling of the mixed rubber sheet is usually carried out by immersing it in a cooling water solution containing an isolation agent. However, the existing cooling system has some shortcomings:

[0003] Insufficient temperature control: During the long soaking process, the temperature of the cooling water solution may gradually increase, which will not only reduce the cooling efficiency but also may adversely affect the quality of the film.

[0004] Separator precipitation problem: Incompletely dissolved separators tend to form sediments at the bottom of the soaking tank, which not only wastes resources but also reduces the efficiency of the separator. In addition, regular cleaning of sediments often requires production suspension, which undoubtedly increases production costs.

[0005] Lack of automated control: Existing cooling systems usually lack effective temperature and liquid level automatic control mechanisms, which not only makes it difficult to achieve the ideal cooling effect, but also the operation process is not environmentally friendly and may pose a threat to the health and safety of operators.
