Description

Technical Field

[0001] The utility model relates to the technical field of dehydration equipment, in particular to a dehydration device for di-tert-butylisopropylbenzene hydroperoxide. Background Art

[0002] Di-tert-Butylisopropylbenzene hydroperoxide (DITBHP) is an organic peroxide with a white to pale yellow appearance. It is insoluble in water but readily soluble in organic solvents such as ethanol and ether. It possesses strong oxidizing properties and thermal stability, and can decompose under certain conditions to produce free radicals, thereby initiating polymerization or cross-linking reactions. In the rubber, plastic, and other polymer materials industries, DITBHP is commonly used as a cross-linking agent, effectively improving the materials' heat resistance, mechanical strength, and chemical stability. It is also used in meltblown fabric manufacturing, enhancing the fabric's toughness and strength through cross-linking.

[0003] Chinese utility model patent authorization announcement number CN220736196U discloses a dehydration device for di-tert-butylisopropylbenzene hydroperoxide, including a feed hopper, a sealing cover is provided at the upper end of the feed hopper, a dehydration bin is provided at the lower end of the feed hopper, a stirring mechanism is provided on the inner side of the dehydration bin, an observation window is provided on the front side of the dehydration bin, a ventilation mechanism is provided on the upper end of the rear side of the dehydration bin, a low-temperature heating box is fixedly installed on the outer side of the lower end of the dehydration bin, support frames are fixedly installed on the left and right sides of the lower end of the low-temperature heating box, and a discharge pipe is provided at the lower end of the low-temperature heating box. By controlling the heating of the low-temperature heating box, the dehydration bin is heated at a low temperature. The drive motor drives the rotating shaft to rotate, causing the stirring blades to rotate and stir the di-tert-butylisopropylbenzene hydroperoxide in the dehydration bin, ensuring uniform heating while accelerating the evaporation of water. The fan operates to allow the water-laden air inside the dehydration bin to enter the air inlet bin, where the filter screen blocks the raw material powder. The air enters the condensation box through the output end of the fan, condensing the water vapor in the air into liquid and collecting it in the liquid collection box. The dry air enters the exhaust bin through the pipe and returns to the inner side of the dehydration bin, achieving circulating drying of the air inside the dehydration bin. However, if the material accumulated at the bottom of the dehydration bin is stirred only by the stirring mechanism, it may still cause uneven heating, resulting in incomplete dehydration or low dehydration efficiency.
