Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of centrifuges, in particular to a high-efficiency centrifugal device for producing oil-based asphalt warm mix agents. Background Art
[0002] In the preparation process of oil-based asphalt warm mix agent, the warm mix agent contains a mixture of solid additives such as modifiers, stabilizers or other additives and base oil. The horizontal centrifuge can effectively separate the mixed solid and liquid phases. Through the action of centrifugal force, the solid particles with a larger specific gravity are separated from the liquid, thereby obtaining a pure oil-based warm mix agent product;
[0003] In the process of using a horizontal centrifuge to prepare warm mix asphalt, if the material viscosity is high or the solid particle size is too fine, it is easy for the material to be difficult to completely separate from the liquid phase under the action of centrifugal force, and thus it is easy to adhere to the surface of the discharge chamber wall, forming a material layer that is difficult to discharge, thereby increasing the difficulty of subsequent cleaning. At the same time, when the horizontal centrifuge is running, if a layer of accumulated material has appeared on the surface of the discharge chamber wall, as the material gradually accumulates, the effective separation area of the centrifuge is reduced, and the solid-liquid separation efficiency is significantly reduced, which may lead to a decrease in the purity of the separated solid or liquid phase of the warm mix asphalt. In addition, frequent shutdowns for cleaning and maintenance will increase additional maintenance costs and downtime losses. Utility Model Content
