[0002] Thermoplastic acrylic resin is used in ink, which can enhance pigment dispersion, improve adhesion, improve rheological property and enhance chemical resistance, and its performance is influenced by molecular weight, functional group and polymer structure, and is widely used in printing, electronics, automobile manufacturing and the like.

[0003] In the process of synthesizing thermoplastic acrylic resin, the moisture in raw materials is returned to the water segregator through the condenser tube together with the solvent and moisture during reflux. Therefore, a water segregator is needed for separation. Patent No. 2004100395214 discloses an automatic drainage water segregator for synthetic resin production. The automatic drainage water segregator adds an automatic drainage device based on the prior art. The automatic drainage pipe is connected to the water drain valve at the bottom of the water segregator, and the height of the drainage outlet of the drainage pipe is lower than that of the reflux pipe. According to the volume of the water segregator, the ratio between the volume of the water segregator and the diameter of the drainage pipe is determined, and the height of the drainage outlet of the drainage pipe is correctly selected, so that the distance between the reflux pipe and the drainage outlet of the automatic drainage pipe can ensure that the organic solvent layer is always separated by the water layer on top, returned to the reaction kettle through the reflux pipe, and the water layer is always at the bottom and discharged from the automatic drainage pipe.

[0004] However, the water segregator in the above patent uses a bottom drainage method, which requires constant control of the water level during separation to avoid the simultaneous discharge of solvent and water from the reflux pipe, thus losing the separation effect. Moreover, since the drainage outlet is located at a low position, it cannot be adjusted, which will affect the separation efficiency of the solvent. Utility model content
