Abstract

The invention provides a stirrer for a reaction kettle. The stirrer comprises a base arranged above a reaction kettle, wherein a rotary output device is fixed on the base and drives a main shaft to extend downwards along the axis of the reaction kettle; a sleeve of which the upper end and the lower end are both closed surrounds the circumference of the main shaft and is coaxial with the main shaft; the sleeve can rotate freely around the main shaft; a spiral wing extending in the axial direction is arranged on the section, in the sleeve, of the main shaft, and only extends to the middle upper part of the section, in the sleeve, of the main shaft; the minimal radial distance between the inner wall of the sleeve and the spiral wing is 0.5-1.0 mm; through holes are formed in the side wall of the sleeve from bottom to top, and the number of the through holes at the same height does not exceed 2. The stirrer for the reaction kettle not only is convenient to mount but also has a favorable material uniform mixing effect.

Description

technical field [0001] The invention relates to the field of chemical machinery, in particular to a reactor mixer. Background technique [0002] For the current reactor mixer, the stirring rod structure is basically adopted, and its principle is very simple. The rotating spindle drives a vertical stirring rod extending into the inside of the reactor, so that the stirring rod rotates around the longitudinal axis of the reactor. The materials in the reaction kettle are stirred to make the materials evenly mixed. [0003] Obviously, the disadvantage of this kind of stirring mechanism is that, because the stirring rod is an off-axis structure, it is difficult to put it into the reactor, or even enter the inside of the reactor for assembly; on the other hand, because the stirring area of ​​the stirring rod is very limited, Cause stirring and mixing effect is not ideal. Contents of the invention [0004] In view of the above problems, the object of the present invention is ...
