Conventional pressure filters generally adopt hydraulic cylinder-driven opening/closing compression mechanisms, and have numerous disadvantages of unreliable multi-cylinder synchronous operation, bad control sensitivity and precision, and the like. The invention proposes an opening/closing compression mechanism driven by a hydraulic cylinder comprising a servo hydraulic valve or by a hydraulic motor in order to realize digital control over position, stroke, speed, pressure and other motion variables and adapt to the work characteristics and need of pressure filters better. The servo hydraulic valve has a hydraulic control valve controlled by a stepping motor, a position sensor and a pressure sensor, and is combined with the hydraulic cylinder or the hydraulic motor as a whole. The mechanism has the advantages of perfect control function, improved sensitivity, precision, work stability and reliability and use convenience. In addition, as a hydraulic system, a motion control system and an electric automatic control system are simplified and less in components, the servo hydraulic transmission mechanism is advanced, reasonable, economical and applicable.
