[0002] Reagent grade potassium nitrate refers to high-purity potassium nitrate with a weight percentage of 98.5% or above. To prepare reagent grade potassium nitrate, the existing process is to dissolve raw materials, then evaporate, crystallize, wash, and perform solid-liquid separation, etc., to finally obtain the finished product. The solid-liquid separation is usually achieved by a centrifugal machine.

[0003] According to the search, the application with patent publication number CN118663430B discloses a solid-liquid separation device for reagent grade potassium nitrate production, which includes a shell and a liquid inlet pipe. A rotating drum with one open end is horizontally arranged in the shell. A filter screen is arranged on the side wall of the rotating drum. The rotating drum is connected with a hollow shaft. A piston rod is movably arranged in the hollow shaft along the radial direction. One end of the piston rod is connected with a pusher plate in the rotating drum. A distribution plate is coaxially arranged on the pusher plate. A liquid outlet pipe and a discharge pipe are arranged on the shell. This can reduce the probability of abnormal material pushing of the centrifugal machine and facilitate material discharge.

[0004] However, due to the arrangement of the centrifugal machine, the solid centrifuged out is easy to adhere to the inner wall of the centrifugal machine, resulting in unclean material discharge and affecting the solid-liquid separation effect.
