Description

Hydrolysis reaction kettle pressure relief device Technical Field The utility model belongs to the technical field of hydrolysis reaction kettles, and particularly relates to a pressure relief device of a hydrolysis reaction kettle. Background Mandelic acid is also called mandelic acid, is white rhombic flaky crystal, is a lipophilic fruit acid, has high affinity with skin, strong permeability and milder action than glycollic acid, and can inhibit proliferation of various bacteria due to the similar chemical structure of the mandelic acid to antibiotics, thus having wider action in the field of medicines. When the hydrolysis reaction kettle heats and cools mandelic acid for a long time, a large amount of gas can be generated in the hydrolysis reaction kettle to be piled up, and under long-time piling up, the air pressure in the hydrolysis reaction kettle is increased along with the time, so that the explosion and other problems of the reaction kettle can be caused. Through retrieval, the patent with the application number 202320376491.4 discloses a pressure relief device of a hydrolysis reaction kettle, which comprises the hydrolysis reaction kettle, wherein a recovery treatment box is fixedly connected to the top of the hydrolysis reaction kettle, an air duct is fixedly connected to the top of the hydrolysis reaction kettle, the other end of the air duct is fixedly connected to the top of the recovery treatment box, a supporting plate is fixedly connected to the inner side wall of the recovery treatment box, and a spiral blade is fixedly connected to the end part of a guide rod. However, in the practical use process, the applicant finds that the gas accumulated in the hydrolysis reaction kettle can move upwards along the spiral blade and push the first sealing plate upwards, so that the first sealing plate is tightly abutted against the second sealing plate, and the first sealing plate cannot smoothly rotate, so that the gas cannot smoothly enter the gas guide pipe through the first gas guide hole and the second gas guide hole to complete pressure relief, and in this regard, we provide a pressure relief device of the hydrolysis reaction kettle.
