Tantalum-niobium ore acid decomposition slurry filter press and filter pressing method thereof

The invention relates to the technical field of tantalite acid decomposition slurry treatment, in particular to a tantalite acid decomposition slurry filter press and a filter pressing method thereof.The tantalite acid decomposition slurry filter press comprises a filter pressing box, and a first filter pressing plate and a second filter pressing plate are alternately arranged in the filter pressing box at equal intervals; the drawing assembly is arranged on the filter pressing box, and the drawing assembly can drive the first filter pressing plate to do reciprocating motion in the filter pressing box; the jacking assembly is connected with the first filter pressing plate and the second filter pressing plate, and the jacking assembly can enable the first filter pressing plate and the second filter pressing plate to move upwards to form a gap with the bottom of the filter pressing box when the drawing assembly drives the first filter pressing plate to move away from the second filter pressing plate; the scrapi
