Description

Technical Field

[0001] The utility model relates to the technical field of acetone glycerol processing, in particular to a continuous reaction synthesis device for acetone glycerol. Background Technique

[0002] Acetone glycerol is a chemical substance with the molecular formula C6H12O3. It is miscible with alcohol ether ester solvents and is an intermediate of batyl alcohol, a "universal solvent", a plasticizer, and a pharmaceutical excipient (a co-solvent and a suspending agent). It is used in the synthesis of mono-, di-, and triglycerides. During the production of acetone glycerol, it is often necessary to react and synthesize it through a continuous stirred tank reactor.

[0003] The "chemical reaction kettle capable of continuous reaction" disclosed in its application number "202320101261.7" "comprises a reaction kettle and a feed pipe. The feed pipe is fixedly installed on the upper side of the reaction kettle and is communicated with the reaction kettle; a motor is fixedly installed on the upper side of the feed pipe, and a loading plate is movably arranged in the feed pipe." In the utility model, a feed pipe for additionally adding materials is arranged. The feed pipe has double seals of a loading plate and a sealing ring, so that the pressure will not leak, increasing the sealing performance of the equipment and the stability during the reaction. When the user needs to additionally add materials for continuous reaction, the materials can be added to the feed pipe, so that the loading plate and the sealing ring are unsealed in sequence for addition, so that the pressure of the reaction kettle will not be greatly affected when adding materials, which is beneficial to the continuous progress of the reaction and increases the practicability of the equipment. In addition, a brush is also arranged, and the brush can clean the residual materials on the inner wall of the feed pipe during the up and down movement of the loading plate, so that the residual materials can enter the reaction kettle, improving the utilization efficiency of resources.

[0004] However, the above method still has the following defects: Materials can be additionally added for continuous reaction through the loading plate and the feed pipe. However, when the raw materials enter the reaction kettle, it is necessary to ensure the feeding space of the loading plate, which will cause the disappearance of the sealing performance, resulting in an instantaneous leakage of pressure. Moreover, it is necessary for the staff to untie the bolts of the sealing ring and remove the sealing ring, which is cumbersome to operate, time-consuming and laborious. Content of the Utility Model
