Pre-pump floating self-cleaning microfiltration device

Abstract

The invention relates to the technical field of filtration equipment and provides a pre-pump floating self-cleaning microfiltration device. The pre-pump floating self-cleaning microfiltration device comprises a holder, a center shaft, a filter screen cylinder, annular end covers and a cleaning pipe, wherein the center shaft is mounted on the holder; the filter screen cylinder sleeves the center shaft correspondingly to a position between the left and right ends of the center shaft; the annular end covers with inner holes sleeving the center shaft are fixedly mounted on the left and right ends of the filter screen cylinder, respectively; the center shaft comprises a cleaning section and a water outlet section; the right end of the cleaning section is fixed with the left end of the water outlet section. The pre-pump floating self-cleaning microfiltration device is reasonable and compact in structure; the center shaft is added to improve the transmission stability of the filter screen cylinder; the cleaning pipe is added to integrate filtration and back washing, and the back washing can be completed at the same time of filtration; the filtration efficiency is high, the back washing is thorough and the blockage is avoided; the filter screen cylinder is flushed continuously to ensure the stability of the filtration efficiency of the filter screen cylinder, the special back washing by virtue of intermittent filtration operation is avoided, and the filtration efficiency can be improved.

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...
