Description

Technical Field

[0001] The utility model relates to the technical field of polyester resin synthesis cooling, in particular to a rapid cooling device for polyester resin synthesis. Background Art

[0002] Polyester resin is a general term for polymer compounds formed by condensation of diols or dibasic acids or polyols and polyacids. Polyester resin reacts and fixes during the synthesis process, and a certain amount of heat is generated during this synthesis process. In order to avoid excessive heat from causing adverse effects on synthesis equipment and products, some technologies have proposed related cooling structures to replicate the synthesis of polyester resins. For example, there is a new patent for use with a publication number of CN219968474U, which proposes a stirring and mixing device for preparing high-leveling polyester resins. Cooling water is injected into the device through a liquid inlet pipe, and the cooling water is discharged through a liquid discharge pipe, so that the cooling water circulates, and valves are provided at one end of the liquid inlet pipe and the liquid discharge pipe. Through this structural design, the interior of the tank can be cooled to avoid excessive heat from causing adverse effects on mixing equipment and products, thereby improving the practical performance of the device and the preparation quality of the polyester resin.

[0003] From the above disclosed technical contents, theoretically speaking, the implementation of the relevant technical structure is beneficial to the cooling during the synthesis process of polyester resin. However, according to the description in the above disclosed technical contents, a cooling chamber is opened inside the mixing tank. Cooling water is introduced from the liquid inlet pipe and flows into the inside of the cooling chamber and then discharged from the liquid discharge pipe, so that the cooling water circulates in the mixing tank. The cooling water not only contains cooling liquid but also easily mixed with impurities. When the cooling water is introduced into the cooling chamber, the impurities in the cooling water will fall to the bottom surface of the inner wall of the cooling chamber under the action of its gravity, and even adhere to the inner wall of the cooling chamber. The cooling chamber is in a closed space, which brings inconvenience to the staff in cleaning the impurities in the cooling chamber. As the number of impurities in the cooling chamber continues to increase, the cooling effect of the cooling chamber on the mixing tank will decrease accordingly, thereby affecting the cooling efficiency of the cooling chamber on the synthesis of polyester resin.
