Stirring device for solid-liquid mixing under high-viscosity condition

Abstract

The invention relates to the technical field of chemical stirring, and discloses a stirring device for solid-liquid mixing under a high viscosity condition. The stirring device comprises a stirring shaft, an upper layer inclined blade downward pressing stirrer, a middle layer frame type stirrer, a lower layer bottom scraping upper stirrer and a fourth hub. The fourth hub is fixed on the lower side of a stirring shaft body. Paddles are evenly arranged on the outer side of the fourth hub. According to the scheme, the stirring device suitable for solid-liquid mixing under the high-viscosity condition can be designed through combined use of the stirrers and improvement and innovation of the blade form of the stirrers. Due to the fact that the viscosity of liquid in the reaction kettle is high, the flow pattern formed by fluid rotating around a shaft is laminar flow, surface tension among liquid molecules prevents mixing of solid media, so that the mixing effect is poor, the edge of a blade of each stirrer is designed to be of a tooth-shaped structure, optimization design is carried out, the shearing force of the blade is increased, the surface tension among the liquid molecules can be damaged, and the stirring effect is improved. Therefore, the solid-liquid mixing effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of chemical industry stirring, in particular to a stirring device for solid-liquid mixing under high-viscosity conditions. Background technique [0002] With the rapid development of the domestic chemical industry in recent years, the demand for chemical mixing has become more and more diversified and complicated. The core component in the mixing tank is the agitator, which completes the physical and chemical processes of the medium (such as suspension, Dispersion, emulsification, mixing, dissolution and absorption, extraction, chemical reaction, heat transfer, etc.) process tools, after the shape of the reactor, material properties and other factors are determined, the flow pattern is related to the structure of the agitator. [0003] At present, many domestic reactions such as the resin industry involve the problem of high-viscosity liquid and solid reaction, because the two phases are relatively special, ...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a stirring device for solid-liquid mixing under high-viscosity conditions, which effectively solves the problems of high-viscosity liquid and solid reactions in many domestic reactions such as the resin industry. Because the two phases are relatively special, the liquid phase has a high viscosity, and the other phase is solid, the reaction time of the two mixed reactions is long, which indirectly causes the problem of large energy consumption, which is very inconsistent with the national energy conservation and emission reduction. policy requirements
