[0026] A sewage extrusion and filtration device of the utility model conveys sewage into the filter press plate 24 through the diaphragm pump 13 in the pipeline assembly. After the conveying is completed, the water inlet valve 15 is closed so that the water inlet of the filter press plate 24 is closed. The hydraulic system drives the push-pull rod 46 to move forward by the movement of the driving end of the hydraulic cylinder 45 therein. The filter press plate 24 is horizontally supported on the two connecting columns 23 by the mounting seats 27 fixed at both ends thereof. By arranging multiple filter press plates 24 adjacent to each other, stability is maintained. The pressing plate 28 slides smoothly on the two connecting columns 23 by means of two rows of rollers 25 installed on both sides thereof. The multiple filter press plates 24 therebetween are extruded by the pressing plate 28 and one side baffle 22, so that the sewage in the filter press plate 24 is extruded and filtered. The filtered clear water is discharged from the water outlet pipe 26, and all the discharged purified water flows into through the opening of the water receiving pipe 31 and is discharged from the lower end through the drainage pipeline. After the impurities in the sewage are filtered out at the filter press plate 24, after the filter press plate 24 is loosened, most of them will automatically fall off, and the remaining small part can be swept off or washed down by a high-pressure water gun, and then the above cycle treatment is continued, which can realize continuous extrusion and filtration of sewage, the overall structure of the device is reliable, and the sewage treatment effect is good.
