[0002] Pour point depressant is an additive used to improve the low-temperature fluidity of petroleum products. It is commonly used in the production of petroleum products such as gasoline and diesel. In the processing of pour point depressant, different raw materials are generally mixed in a certain proportion, and a mixing barrel is usually used for mixing and stirring. The outer side of the rotating shaft of the existing mixing barrel is provided with multiple layers of stirring blades. When the raw material ratio changes, the density of the raw material mixed fluid changes, which will cause flow dead zones between the layers of the stirring blades. Since the position of the stirring blades and the rotating shaft is fixed, the flow rate of the mixed raw materials in the flow dead zone is slow, which will cause the raw materials of the pour point depressant to be unable to be completely dispersed, affecting the mixing processing of the pour point depressant. In order to solve this problem, a new type of processing device for mixing pour point depressants is needed. Utility Model Content
