Floating self-cleaning microfiltration device in front of the pump

Abstract

The invention relates to the technical field of filtration equipment, and is a floating self-cleaning microfiltration device in front of a pump, which includes a fixed frame, a central shaft, a filter screen cylinder, an annular end cover and a cleaning pipe, and a central shaft is installed on the fixed frame, corresponding to the central shaft The outside of the central shaft between the left and right ends is fitted with a filter screen tube, and the left and right ends of the filter screen tube are respectively fixed with ring-shaped end caps with inner holes set on the outside of the central shaft; the central shaft includes a cleaning section and a water outlet section. The right end of the segment is fixed together with the left end of the outlet segment. The invention has a reasonable and compact structure, and can improve the stability of the transmission of the filter screen cylinder by adding a central axis; by adding a cleaning pipe, it can integrate filtering and backwashing, and can complete backwashing while filtering, improving the efficiency of filtering High, backwash thoroughly, not easy to clog, it can ensure the stability of the filtration efficiency of the filter cartridge through uninterrupted flushing of the filter cartridge, and do not need to perform backwashing for intermittent filtration operations, which can improve the filtration efficiency.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, and relates to a floating self-cleaning microfiltration device in front of a pump. Background technique [0002] There is a shortage of water resources in the north. At present, agricultural water consumption accounts for the main part of the total water consumption. Alleviating the contradiction between supply and demand of water resources, establishing a long-term water-saving agricultural mechanism, and realizing the rational use of water resources are the only ways to develop water-saving agriculture. In order to meet the water quality standard of drip irrigation for water-saving irrigation, it is required to separate raw water from sand and suspended matter during use. Currently, common methods for solid-liquid separation of raw water include: natural sedimentation, sand filtration, and mesh filtration. Natural sedimentation is to introduce raw water into a pool with a certain v...
