Therefore, under the action of the rotation of the stirring blades, the materials in different parts of the kettle body will have different stirring amplitudes. During the stirring process, different amplitudes are superimposed on each other. Therefore, the stirring process in the reactor is Irregular, and it is easier to mix the materials evenly.

Preferably, the runner further includes a second stirring blade, the surface of the stirring blade facing away from the rotating shaft is provided with a first through hole, and the second stirring blade is provided with a second through hole capable of matching with the first through hole. The hole and the fixing piece arranged in the second through hole.

By adopting the above technical scheme, the second stirring blade is placed on the stirring blade, and then the fixing member is used to pass through the first through hole and the second through hole in sequence, thereby completing the fixing of the second stirring blade and the stirring blade, and using Because of the lengthening of the stirring blade, the effect of strengthening the stirring is more enhanced.

Preferably, the rotating shaft includes a rotating shaft sleeve and a threaded rod screwed into the rotating shaft sleeve.

By adopting the above technical scheme, the threaded rod is screwed into the shaft sleeve, and the stirring blade is arranged on the threaded rod; when the reactor is in operation, the threaded rod can be screwed out to different lengths according to actual needs.

Preferably, the rotating shaft further includes a fixing sleeve for locking the relative position of the threaded rod and the rotating shaft sleeve.

By adopting the above technical scheme, since the threaded rod is screwed into the shaft sleeve, in order to prevent the threaded rod from falling off from the shaft sleeve during the mixing operation, the fixing sleeve can be used to fix the two to avoid the screw rod Comes off the threaded sleeve.

Preferably, the fixed sleeve is screwed onto the rotating shaft, a projection is provided on the surface of the sleeve of the rotating shaft facing the fixed sleeve, and a first groove capable of fitting with the projection is provided on the fixed sleeve.

By adopting the above technical solution, the fixed sleeve is screwed onto the rotating shaft, and then the threaded rod is screwed into the sleeve of the rotating shaft, and the protrusion is fitly inserted into the first groove.

In summary, the utility model has the following beneficial effects: after the material to be processed is introduced into the kettle body from the feed port, the power device drives the stirring paddle to rotate; during the stirring process, such as acrylic polyurethane, etc. It is difficult to mix all the materials in the kettle evenly only by the rotation of the stirring shaft, especially the materials on the edge of the reactor cannot be turned over under the stirring action of the stirring paddle; therefore, there are several on the inner wall of the kettle. The runner, the runner rotates under the driving action of the driving device, and the stirring blade turns the material close to the edge of the reactor, so as to stir faster and better.
