Technical Field

[0001] The utility model relates to the technical field of polyether processing equipment, in particular to a separation device for polyether oxidation reaction. Background Art

[0002] With the continuous development of the chemical industry, polyether, as an important chemical raw material, has an increasingly wide range of applications. However, polyether is prone to oxidation reactions during production, storage and use, which not only reduces the quality and performance of the polyether, but also may pose a safety hazard. At present, the commonly used polyether separation methods mainly include distillation and extraction. Although these methods can achieve the separation of polyether to a certain extent, they often cannot effectively reduce the risk of polyether oxidation reactions. For example, heating is required during the distillation process, and high temperature may accelerate the oxidation of polyether; new impurities may be introduced during the extraction process, and these impurities may also promote the oxidation of polyether. In order to solve the above problems, a separation device for polyether oxidation reaction is needed.

[0003] The existing polyether separation device cannot prevent oxidation reaction during operation, is inconvenient to replace the filter element, and is inconvenient to pressurize and separate the polyether solution. Therefore, a separation device for polyether oxidation reaction is urgently needed. Utility Model Content

[0013] Preferably, the pressure head is tightly fitted with the inner wall of the connecting sleeve, and the positioning rod is snap-connected with the positioning groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is equipped with an inflator, a display screen, a gas storage tank and a conduit. By starting the inflator, an inert gas such as nitrogen, argon or helium in the gas storage tank is injected into the interior of the device body through the conduit, thereby reducing the oxygen content inside the device body and preventing the polyether solution inside from undergoing oxidation reaction.

[0016] 2. The utility model is provided with a fixed disk, a sealing ring, a filter membrane core, a limit spring and a limit push rod. After the limit push rod is pressed inward and the fixed disk is placed in a suitable position inside the device body, the limit push rod is pushed out by the elastic force of the limit spring, so that the limit push rod is engaged and fixed with the device body, which is convenient for disassembly and replacement.
