Washing system of rare earth oxalate precipitation

The invention relates to the field of rare earth product producing apparatuses and especially relates to a washing system of rare earth oxalate precipitations. The system includes a rare earth oxalate reaction kettle and a precipitation washing apparatus. The reaction kettle is arranged above the precipitation washing apparatus and is connected to the precipitation washing apparatus through a pipeline. The precipitation washing apparatus comprises a filtering barrel, a vacuumizing apparatus and a water collecting barrel. A water discharge pipe and a gas discharge pipe are disposed on a lower part of the filtering barrel and the other end of the filtering barrel is connected respectively to the water collecting barrel and the vacuumizing apparatus. In the system, the precipitations are washed and filtered in the self-made filtering barrel and the washing process is divided into a plurality of steps, wherein water, except in a first washing step, in the other steps are all collected for washing the follow-up precipitation while the water in the first washing step is discharged out, so that utilization rate of water resource can be greatly increased and waste water discharge is reduced. By means of a vacuumizing process after the washing process, moisture in the precipitations can be effectively removed for reducing volume of the rare earth oxalate precipitations, so that a subsequent burning time can be shortened, energy required in burning is saved, a production period of a rare earth oxide is shortened and a production cost is reduced.
