Description

Technical Field

[0001] The utility model relates to the technical field of drying kettles, in particular to a heating mechanism of a waterborne polyurethane chain extender drying kettle. Background Art

[0002] Waterborne polyurethane is widely used in household goods, interior decoration, medical equipment, food processing, packaging industry and other fields due to its excellent performance, environmentally friendly characteristics and low price.

[0003] In the prior art, a patent document with publication number CN220559189U proposes a heating mechanism for an oxidation reactor, including an oxidation reactor body, a support frame, a storage barrel, a connecting pipe and a discharge pipe. The utility model starts a uniform heating mechanism by setting a control panel, so that the uniform heating mechanism is adjusted and moved for uniform heating, thereby solving the problem that the existing oxidation reactor is used. Although the possibility of material spilling during the pouring process is reduced, thereby wasting materials, the oxidation reactor often needs to heat the internal materials during the reaction of the materials to increase the reaction speed of the materials inside the oxidation reactor. However, the oxidation reactor cannot heat the materials uniformly during use, resulting in different reaction rates of the materials reacting in the oxidation reactor, which greatly affects the accurate efficiency of the reaction of the reactants in the reactor. Therefore, the oxidation reactor is heated unevenly during use, which reduces the use effect of the oxidation reactor.

[0004] In order to solve the problem that the reactor cannot heat the material uniformly during use, the prior art adopts a method of starting the uniform heating mechanism by setting a control panel, and adjusting and moving the uniform heating mechanism to perform uniform heating. However, it is inconvenient for the device to heat the outer surface of the reactor during use, which reduces the practicality of the heating mechanism. Utility Model Content
