Self-cleaning mesh cylinder type continuous filter

Abstract

The invention relates to the technical field of water-saving irrigation filter devices and provides a self-cleaning mesh cylinder type continuous filter. The filter comprises a filtering mesh cylinder, a sewage discharge rotating shaft, a flushing pipe rack and a dirt collecting tank. The filtering mesh cylinder is a transverse cylinder with the axis arranged horizontally. A left conical cylinderring with a small left part and a big right part is fixed to the left end of the filtering mesh cylinder, a right conical cylinder ring with a big left part and a small right part is fixed to the right end of the filtering mesh cylinder, and a left spindle base is fixed to the left conical cylinder ring or the center of an inner cavity in the left end of the filtering mesh cylinder. The filter isreasonable and compact in structure and convenient to use. High-pressure water flow jetted out by the flushing pipe rack flushes the upper portion of the filtering mesh cylinder and drives the filtering mesh cylinder to rotate so that mesh holes can be prevented from being blocked, formation of filtering cakes is prevented, and the filtering area is increased. The dirt collecting tank and a sewagedischarge shaft cavity are used for continuously discharging dirt, so that filtration and sewage discharge are simultaneously performed without interfering each other, and the filtration efficiency is improved while the energy consumption is reduced. The filter is used for sediment filtration before pumping so that the loss of a water head can be significantly reduced and energy can be remarkablysaved. The filter has the advantages of a simple structure, high efficiency and energy saving.

Description
