Detailed Description

A stirring reactor as shown in fig. 1 to fig. 3, comprising a reactor body 11, a central shaft 26 is fixed in the center of the reactor body vertically and downwardly in a rotatable manner, an upper stirring vane 21 and a lower stirring vane 22 which are parallel to each other are fixed on the central shaft 26, the upper stirring vane 21 and the lower stirring vane 22 are opposite in rotation direction, a top paddle 23 is fixed on the central shaft 26 at a position higher than the upper stirring vane 21, a bottom paddle 25 is fixed at a position lower than the lower stirring vane 22, and a side paddle 24 is fixed on the side paddle 24 or the bottom paddle 25 at a position opposite to the outer side of the outer ends of the upper stirring vane 21 and the lower stirring vane 22. The main principle of uniform stirring is that the upper stirring blade 21 and the lower stirring blade 22 cause opposite flow directions, liquid is oppositely flushed between the upper stirring blade 21 and the lower stirring blade 22 and then diffused to the side, and is stirred by the side blades 24, the top blades 23 and the bottom blades 25 to form turbulent flow, meanwhile, the top blades 23 and the bottom blades 25 are used for firstly stirring the opposite flow of the upper stirring blade 21 and the lower stirring blade 22, so that regular flow directions are avoided, and the bottom blades 25 are used for taking up part of the liquid at the bottom of the kettle body 11 to avoid forming deposition, thereby effectively ensuring uniform stirring.

Further, in order to ensure the stirring effect of the side blades 24 on the liquid and avoid the side blades 24 from rotating to form a side surface regular flow direction, the distance between the outer side edge of the side blade 24 and the inner wall of the kettle body 11 is less than 50 mm.

Specifically, the number of the side blades 24 is two, and the side blades are symmetrically distributed.

Further, in order to ensure the driving effect of the bottom blades 25 on part of the liquid at the bottom of the kettle body 11, the distance from the lower edges of the bottom blades 25 to the bottom in the kettle body 11 is less than 70 mm.

Furthermore, the bottom paddle 25 is a left-right symmetrical structure with a single-side middle section bent downwards.

In order to ensure the structural stability of the top blade 23, the side blades 24 and the bottom blade 25, the top blade 23, the side blades 24 and the bottom blade 25 form a closed frame structure.

As a most preferable scheme for ensuring the stirring rotation stability, the top end of the central shaft 26 is fixed on the output shaft of the stirring motor 27, and the stirring motor 27 is fixedly arranged at the center of the top of the kettle body 11 facing downwards.

As the most preferable realization scheme of the heating function requirement, the kettle body 11 is provided with an inner wall and an outer wall, and a heating pipe is arranged between the inner wall and the outer wall.

Specifically, the heating pipe is a longitudinal heating pipe 31 installed longitudinally and/or a transverse heating pipe 32 installed transversely.

Generally speaking, a manhole 13 is arranged at a non-central position on the top of the kettle body 11; the central position of the bottom of the kettle body 11 is externally connected with a liquid outlet pipeline 14; an observation window 15 is arranged at the non-central position of the top of the kettle body 11.

Generally, the kettle body 11 is fixedly installed through a fixed seat 12 on the outer side wall.

Example 1

By adopting the scheme, the stirring motor 27 is fixed on the side of the top of the kettle body 11.

By adopting the mode, better stability can be kept in high-speed stirring, but fasteners such as screws and the like are easy to fall off in long-time low-speed stirring work.

Example 2

By adopting the above scheme, the bottom paddle 25 is a straight-line strip structure with bilateral symmetry.

In this way, in order to ensure that the liquid at the bottom of the kettle 11 can be uniformly stirred, the stirring motor 27 needs to be started to start stirring before the liquid is added.
