The invention discloses a
polymer microsphere production device which comprises a reaction
tower. A first liquid is filled in the reaction
tower, the reaction
tower is in a straight cylinder shape, a plurality of liquid spraying pipes are arranged at the bottom of the reaction tower, inlets of the liquid spraying pipes are communicated with a liquid supply
pipe filled with a second liquid outside the reaction tower, outlets of the liquid spraying pipes point to the inside of the reaction tower, and the liquid spraying pipes comprise nozzles. A
nozzle impact mechanism is also arranged and comprises a driving mechanism and an
impact rod, the driving mechanism is mounted on the periphery of the reaction tower, the
impact rod penetrates through the reaction tower and points to the nozzles in the radial direction, and the number of the
nozzle impact mechanisms is consistent with that of the nozzles. The invention also provides a production method of the
polymer microsphere. Disturbance of reaction liquid during production of the
polymer microspheres can be avoided, and the polymer microspheres with
small particle size and uniform distribution can be prepared; meanwhile, the equipment is simple,
continuous production can be realized, and the production efficiency of the polymer microspheres is greatly improved.
