The bubbles generated during the reaction of cerium nitrate are located in the middle and upper part of the reactor body 1. When the bubbles contact with the multiple puncture needles 36, the bubbles will burst to achieve defoaming. At the same time, the rotating rods 35 are arranged in a uniform array on the periphery of the first sleeve 34. The first sleeve 34 drives the rotating rods 35 to rotate under the action of the rotation of the rotating shaft 21, so that the bubbles can better contact with the puncture needles 36 for defoaming, thereby improving the defoaming efficiency. The defoaming is carried out by mechanical treatment without the use of defoaming agents, which is conducive to environmental protection.

[0024] In some preferred embodiments, an annular tube 30 is provided on the outer periphery of the rotating rod 35, a nozzle 33 is provided at the bottom of the annular tube 30, and a vacuum pump 32 is provided with a connecting tube 31, and one end of the connecting tube 31 away from the vacuum pump 32 is connected to the annular tube 30.

At the same time, the first stirring rods 23 located on both sides of the second stirring rod 24 are stacked on each other, and the second stirring rod 24 is connected to a connecting plate 26 with a cleaning brush 27, and the cleaning brush 27 is in contact with the inner wall of the reactor body 1, so that when the second stirring rod 24 rotates, the cleaning brush 27 will clean and collect the reactant crystals attached to the inner wall to prevent crystallization from occurring on the inner wall of the reactor body 1. The second stirring rod 24 can be a straight rod or a movable telescopic rod, which can be selected according to actual needs.

[0030] In some preferred embodiments, a plurality of blades 25 are provided below the second sleeve 22 at the bottom. The bottom of the reactor body 1 of the utility model is bucket-shaped, so cerium nitrate and the reaction liquid are easily accumulated there, and the blades 25 can stir the bottom under the action of the rotating shaft 21, so that the reactants at the bottom are evenly mixed, thereby further improving the reaction rate.
