technical field

The invention relates to a stirring paddle for mixing liquid-solid two-phase materials or liquid-liquid-solid three-phase materials, in particular to a high-viscosity material mixing paddle.

Background technique

In the production process of petrochemical industries such as rubber, plastics, and oil refining, it is often encountered in the mixing of viscous liquid-solid two-phase materials or liquid-liquid-solid three-phase materials. The stirring paddle is the core part of the stirring reactor, which can provide a suitable flow form for the fluid, promote the mixing of materials, and improve the chemical reaction. At present, the commonly used mixing paddles for mixing viscous materials use anchor (or frame) paddles to stir and mix. These two types of paddles have uneven mixing in the center area of the paddle and the lower end of the paddle during use, and solid materials are easy to accumulate. The phenomenon at the bottom of the tank affects the mixing effect of various materials and the efficiency of chemical reactions.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a new type of combined mixing paddle, including motor 1, coupling 2, transmission belt 3, frame type paddle (outer paddle) 4, double-layer inclined blade paddle (inner paddle) 5, transverse block Plate 6, stirring shaft 7, variable inclination propulsion paddle (inner paddle) 8, and motor 9. In terms of structure and its combination, the technical features of the present invention are: a new type of combined paddle consists of an outer frame paddle (outer paddle) 4, a double-layer inclined blade paddle (inner paddle) 5, and a variable-inclination propulsion paddle (inner paddle) 8 Composition; the frame paddle (outer paddle) 4 is provided with a transverse baffle 6, driven by the motor 9, the horizontal baffle 6 rotates together with the frame paddle (outer paddle) 4, which can increase the stirring liquid in the stirring tank The degree of mixing inside avoids the situation that the static horizontal baffle is installed on the cylinder, and the material settling area is easily formed behind the baffle; the frame paddle (outer paddle) 4 is close to the inner wall of the reactor to scrape off the material attached to the tank. The effect of viscous material on the inner wall;

Variable-inclination impeller propulsion paddle (inner paddle) 8, with different inclination angles, constantly changes the flow state of the mixed material during the stirring process, increases the turbulence of the mixed material, and promotes the mixing between materials of each phase; the inner paddle is made of variable inclination angle The propulsion paddle 8 and the double-layer inclined-blade paddle 5 are combined. The variable-inclination propulsion paddle 8 can realize the overall mixing of the fluid in the tank and eliminate the problem of material accumulation in the tank. It has good advantages in pulverization and fine mixing. The combination of two kinds of stirring blades is more conducive to the overall macroscopic mixing and microscopic mixing of materials, and at the same time eliminates the problem of uneven mixing in the central area of the tank.
