Problems solved by technology

Using the cylinder as the actuator can realize the timely adjustment of the scraper state, but because the installation of the cylinder is relatively complicated, it is easy to cause the structure of the overall unloading device to be huge
At the same time, for highly corrosive working conditions, the seal of the moving parts of the cylinder is prone to corrosion, resulting in air leakage and failure

Abstract

The invention relates to a scraper discharging device, in particular to the scraper discharging device of filtration fabric of a rubber belt type vacuum filter. The scraper discharging device comprises a scraper support saddle and a scraper bracket arranged on the scraper support saddle, wherein the scraper bracket is pivoted with a scraper by a bearing; the scraper comprises a scraper body and a squeeze plate for squeezing the scraper body; the scraper body and the squeeze plate are positioned at the two sides of the bearing respectively; one ends of a plurality of bent levers are fixedly connected with the squeeze plate of the scraper; and the other ends of the bend levers are linked with an air bag. The output force of the air bag can be controlled by adjusting inlet pressure through a pressure regulating valve so as to conveniently adjust condition of the action of the scraper and a discharging roll and avoid damage to the filtration fabric.

Description

technical field [0001] The invention relates to a scraper unloading device, in particular to a scraper unloading device for filter cloth of a rubber belt vacuum filter. Background technique [0002] Vacuum filter is used in various solid-liquid separation equipment. [0003] The general principle of the unloading device of the rubber belt vacuum filter: the filter cake dried by vacuum suction moves continuously with the filter cloth. When it runs to the unloading roller, its curvature becomes larger (the radius of curvature becomes smaller) , so that the filter cake is easier to peel off the filter cloth, and then the filter cake is peeled off and discharged with a scraper wire or a thin plate scraper. [0004] At present, the unloading device used in the rubber belt vacuum filter has a hammer type scraper device. The composition mainly includes a scraper bracket, a scraper, a scraper support, a heavy hammer, etc., and the initial scraper adjustment is performed by the cou...
