Description

Technical Field

[0001] The utility model relates to the technical field of polyester resin processing equipment, in particular to a reaction kettle for synthesizing polyester resin for coatings. Background Art

[0002] At present, researchers in related fields have proposed some solutions to the problem of inconvenient material removal in the reactor used in the polyester resin synthesis process. For example, the authorized patent with announcement number CN214234026U and the main name of a polyester resin synthesis reactor proposes "a liquid inlet is set on one side of the fixed sleeve, a threaded connection between the liquid collection tube and the fixed sleeve, and one end of the liquid collection tube is set at the top of the liquid inlet, which can effectively remove the reagent inside the reactor body through the liquid inlet. After the reagent is removed, the liquid inlet is sealed through the tube sleeve, which effectively solves the problem that the gas inside the reactor is easy to overflow from between the sampling liquid collection tube and the liquid collection port when taking reagent samples."

[0003] From the technical solutions and corresponding technical effects disclosed in the above-mentioned prior art, it is seen that a method for collecting samples in a relatively closed manner is disclosed, which can avoid the gas overflow in the reactor during the sample collection process. However, from the perspective of practical operation, if the operation is carried out according to the method of the above-mentioned prior art, multiple manual intervention operations are required, and the operation is cumbersome. Secondly, the sealing effect is general, because it is a manual collection operation, and the probability of gas overflow inside the reactor due to operational errors is still very high.
