Abstract
A pressure filter includes a hydraulic device, a pressing device, and two filter plates. A guide beam is fixed to the hydraulic device and the pressing device. The hydraulic device has a piston rod movably mounted on the guide beam. The piston rod is connected to a push plate. The filter plates are mounted on the guide beam. The push plate and the pressing device are disposed at two sides of the set of the filter plates. The pressing device has a first feed inlet. The push plate has a second feed inlet. Each filter plate has a material through hole. Two adjacent filter plates are connected end to end. The material through hole forms a material channel. The first and second feed inlets both communicate with the material channel. The feed speed is greatly increased and the filter effect is also improved.
Claims9
A pressure filter, comprising:
- a hydraulic device and a pressing device forming an assembly, and
- at least two filter plates,
- wherein a guide beam spans across the hydraulic device and the pressing device and has a first end thereof fixed at a first end of the assembly of the hydraulic device and the pressing device, and has a second end of the assembly of the hydraulic device and the pressing device,
- 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 at least two filter plates being tandem mounted on the guide beam as a group so that the push plate is located at a first end of the group of filter plates and the pressing device is located at a second end of the group of filter plates, 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 at least two 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 each of the at least two filter plates has two sides thereof peripherally provided with different ridges each ridge formed as a closed loop, so that when two adjacent of said at least two filter plates are pressed together, the ridges at contacting sides of the adjacent pressed together filter plates are offset to jointly define a vacant space there between;
- wherein at each of the sides of the at least two filter plates, columnar protrusions are evenly distributed all over an area circled by the ridge, and all of the columnar protrusions have top surfaces thereof level with each other, wherein a base level of the at least two filter plates from which the columnar protrusions are extended outward becomes thicker as it goes toward a periphery of the at least two filter plates, and the columnar protrusion near the periphery of the at least two filter plates has a height smaller than a height of the columnar protrusion far away from the periphery of the at least two filter plates.
