[0002] Reactor is a kind of equipment widely used in the fields of chemistry, chemical industry, petroleum, medicine, food, etc. It is a container for physical or chemical reactions. Reactor is usually equipped with a stirring system, which is used to fully stir the materials to make them react fully.

[0003] Generally speaking, a reactor is equipped with only one type of stirring blade. However, due to the different viscosities and dispersion levels of different reaction materials, blades of different shapes and sizes are required. Therefore, the stirring blades in a reactor can generally only be used for one type of product.

[0004] However, for factories with intermittent chemical reactions such as pharmaceutical factories, in the process of changing product series, one reactor needs to produce several products, so the viscosity, composition and dispersion requirements of the materials in the reactor are different, but the applicable stirring blades cannot be replaced, which leads to a decline in product quality and cannot be guaranteed.

The bolt holes on the flange and the bolt holes on the impeller flange are distributed on the same size circumference.

[0008] The impeller can be optionally mounted on a flange on the mixing shaft.

[0009] The diameter, number of bolt holes and diameter of the flange are consistent with the diameter, number of bolt holes and diameter of the impeller flange.

[0010] The impeller is a propeller impeller, a paddle impeller, a turbine impeller, an anchor impeller, a frame impeller, a ribbon impeller or a screw impeller.

[0011] The flanges are symmetrically distributed on both sides of the stirring shaft.

[0012] The flanges are distributed on the stirring main shaft in 2 to 5 layers.

[0024] The utility model is now further described with reference to the accompanying drawings.

[0025] See also Figures 1 to 4 The utility model provides a novel stirring paddle system for a reactor, comprising a stirring main shaft 1, a connecting piece 2, a flange 3 and an impeller. Flanges 3 are arranged on both sides of the stirring main shaft 1 through the connecting piece 2. The flange 3 on the connecting piece 2 is connected to the impeller flange on the impeller. The bolt holes on the flange 3 and the bolt holes on the impeller flange are distributed on the same size circumference.

[0026] The impeller can be optionally mounted on a flange 3 on the stirring main shaft 1 .

[0027] The diameter, number of bolt holes and diameter of flange 3 are consistent with the diameter, number of bolt holes and diameter of the impeller flange.

[0028] The impeller is a propeller impeller, a paddle impeller, a turbine impeller, an anchor impeller, a frame impeller, a ribbon impeller or a screw impeller.

[0029] The flanges 3 are symmetrically distributed on both sides of the stirring main shaft 1 .

[0030] The flange 3 is distributed on the stirring main shaft 1 in 2 to 5 layers.

[0031] The connecting piece 2 is a thick-walled tube or a solid tube.

[0032] The length of the connecting piece 2 is 5 to 20 cm.

[0033] Flange 3 at 3m 3 The following small reactors have four bolt holes when used, and at 3m 3 The above large reactor has eight bolt holes when used.

[0034] Working principle:

[0035] The utility model does not require much debugging. The flange 3 of the same material as the main shaft is provided on the stirring main shaft 1 through the connecting piece 2. The flange 3 is provided with corresponding bolt holes according to the size of the reactor used. Impellers of different types and shapes can be selected according to the viscosity of the material to be stirred. The impeller is installed as a whole with the flange 3 through the flange.

[0036] The characteristic of the utility model is that, since a symmetrical, multi-layer flange 3 is provided on the stirring main shaft 1, a refined impeller setting can be equipped according to actual personalized needs, and different impellers are equipped at the positions of the flanges 3 of different layers to form a diversified stirring system, and the blade angle on the impeller can be adjusted by adjusting the corresponding relationship between the flange 3 and the bolt holes on the flange of the impeller to further adapt to materials with different viscosities and dispersion requirements. At the same time, it can also be combined with a multi-stage variable frequency mixer to output different rotation speeds to further adapt to materials with different viscosities and dispersion requirements in the reactor.
