Therefore, it is easy to cause the raw materials to accumulate in the discharge pipe and cannot be stirred, resulting in uneven stirring of some raw materials, affecting the mixing efficiency. For this reason, we propose a matte resin polymerization reactor. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the utility model is stirring, the electric push rod is extended to drive the connecting plate and the second discharge pipe to slide and lower along the first discharge pipe, so that the second discharge pipe is retracted into the inner cavity of the first discharge pipe, and the first discharge pipe is closed with the sealing piston, so that the raw materials will not enter the first discharge pipe and will only remain in the inner cavity of the reactor, so that the phenomenon of not being able to stir will not occur easily.
