Embodiment 1

[0019] A kind of agitator, its stirring main paddle 1 has a first-level dispersion stirring branch 2, a second-level dispersion stirring branch 3 is arranged on the first-level dispersion stirring branch 2, and there are two first-level dispersion stirring branches 2 on the stirring main paddle 1, one The angle between the primary dispersing and stirring branch 2 and the secondary dispersing and stirring branch 3 is 90°, and there is a tertiary dispersing and stirring branch 4 above the secondary dispersing and stirring branch 3, which forms a certain angle with the secondary dispersing and stirring branch 3. Its shape is jagged.

Embodiment 2

[0021] A kind of agitator, its stirring main paddle 1 has a first-level dispersion stirring branch 2, a second-level dispersion stirring branch 3 is arranged on the first-level dispersion stirring branch 2, and the number of first-level dispersion stirring branches 2 on the stirring main paddle 1 is four, two The angle between the stage dispersing and stirring branch 3 and the primary dispersing and stirring branch 2 is 30-150°, and its shape is tree-like.

[0022]

[0023] The present invention will be described in detail below in conjunction with specific test examples. The test examples are saw-toothed stirring paddles and tree-shaped stirring paddles, and the prior art is anchored stirring paddles, but not limited thereto.

Abstract

The invention discloses a stirrer. A stirring paddle has a multi-level structure and comprises a stirring main paddle, wherein a first-level dispersing stirring branch is arranged on the stirring main paddle; second-level dispersing stirring branches arranged on the first-level dispersing stirring branch; the plurality of second-level dispersing stirring branches and the first-level dispersing stirring branch form a certain angle; third-level dispersing stirring branches are arranged above the second-level dispersing stirring branches; and the third-level dispersing stirring branches and the second-level dispersing stirring branches form a certain angle. The stirrer has the advantages of increasing the shearing force of the stirring paddle and improving dispersive capacity and also has the advantages of high stirring effect and high efficiency particularly for a solid liquid crystallization system. More importantly, through stirring, products can be prevented from being left over for many times and the resin color is improved.

Description

technical field [0001] The invention relates to a stirrer, especially a stirrer for stirring high-viscosity resin. Background technique [0002] Stirring device is a kind of material mixing and dispersing equipment commonly used in chemical production. During the reaction process, it can promote the flow of materials in the kettle, make the materials evenly distributed, increase the mass transfer and heat transfer coefficient, etc., and sometimes even affect the To the reaction speed and reaction conversion rate, the stirring paddle used for stirring plays a greater role in it. A well-designed stirring paddle can not only promote the chemical reaction process, but also reduce energy consumption and improve efficiency. [0003] The shapes of conventional stirring paddles include anchor type, paddle type, turbine type, propulsion type, frame type, etc. Different shapes of stirring paddles correspond to different reaction conditions and use environments to meet different use re...
