Suction filtration roller structure of belt-type vacuum filter

The utility model relates to the technical field of belt-type vacuum filters, in particular to a suction filtration roller structure of a belt-type vacuum filter. The suction filtration roller structure comprises a suction filtration roller, wherein a plurality of liquid suction grooves are circumferentially formed in the suction filtration roller, and the right ends of the liquid suction grooves are communicated with through holes through hoses; one end of a fixing screw passes through the first central hole of a first distribution plate to be in threaded connection with the screw hole of a shaft head end surface II at the right end; one end of a connecting shaft is closely nested into the second central hole of a second distribution plate, and the other end of the connecting shaft is closely nested into the liquid suction fixing hole of a liquid suction end; a plurality of round through holes matched with the through holes are circumferentially formed in the first distribution plate, and the arc angle between the centers of semicircles at the two ends of an arc-shaped through groove is 90-110 degrees. During use of the suction filtration roller structure, unnecessary atmosphere can be prevented from being sucked, and the vacuum suction degree of the suction filtration roller is greatly increased, so that the belt-type vacuum filtering efficiency is improved; the suction filtration roller structure has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.
