20160114266 | PRESSURE FILTER - 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. | 04-28-2016 |
20160121241 | LARGE-SIZED FILTER PLATE - A filter plate has two sides thereof peripherally provided with different ridges each formed as a closed loop, so that when two filter plates are pressed together, the ridges at contacting sides of the adjacent filter plates are offset to jointly define a vacant space having a width of 3-5 mm. The ridges at the two sides of the filter plate have a flat top surface and a pointy or curved top surface, respectively. When the two filter plates are pressed together, the vacant space formed between the flat top surface of the ridge of one of the filter plates and the pointy or curved top surface of the ridge of the other filter plate is closed, wherein the ridge having the flat top surface forms an inner-circle sealing and the ridge having the pointy or curved top surface forms an outer-circle sealing. | 05-05-2016 |
