Cake removing apparatus for use in filter press

In a filter press comprising a multiplicity of filter plates each covered with a filter fabric over each of front and rear filter faces thereof, a fabric hanger bar attached to an upper edge of each of the front and rear filter fabrics, connecting members connecting together the opposed ends of the hanger bars opposed to each other between each two adjacent filter plates, and a movable frame movable forward and rearward, a cake removing apparatus characterized in that the movable frame has a pair of front and rear arms each having a main fabric beating member at an outer end thereof, the beating members being positionable above and at the respective front and rear outer sides of the filter fabrics opposed to each other as pulled outward from two open adjacent filter plates after filtration approximately to an inverted V shape when seen from one side of the press, an auxiliary fabric beating member attached to and suspended from each of the arms and disposed below the main fabric beating member, the auxiliary fabric beating members being positionable above and at the respective front and rear outer sides of the opposed fabrics, means for pivotally moving the arms so that the main and auxiliary fabric beating members beat the opposed filter fabrics each on the rear surface thereof opposite to its cake adhering surface, and a lift mechanism for reciprocatingly moving the arms and the arm moving means between an upper position between the open two filter plates and a lower position where the opposed filter fabrics are to be beaten.
