1. A pressure filter, comprising:
a hydraulic device, a pressing device, and at least two filter plates, wherein a guide beam spans across the hydraulic device and the pressing device and has two ends thereof fixed at two ends of the assembly of the hydraulic device and the pressing device, respectively, the hydraulic device having a front end provided with a piston rod, the piston rod being movably mounted on the guide beam, the piston rod having a front end connected to a push plate, the filter plates being tandem mounted on the guide beam as a group so that the push plate and the pressing device are located at two ends of the group of the filter plates, respectively, and the pressure filter being characterized in that the pressing device is provided with a first feed inlet, and the push plate is provided with a second feed inlet, wherein each of the filter plates has a material through hole, and the adjacent two filter plates are connected end to end so that the material through holes jointly form a material channel and the first and second feed inlets are both communicated with the material channel; wherein the filter plate has two sides thereof peripherally provided with different ridges each formed as a closed loop, so that when two said filter plates are pressed together, the ridges at contacting sides of the adjacent filter plates are offset to jointly define a vacant space there between. |
