Water turbine driven microfilter

Abstract

The invention relates to the technical field of filtration equipment and relates to a hydroturbine propelled microfilter. The hydroturbine propelled microfilter comprises a holder, a filter screen component, a cleaning pipe and a hydroturbine, wherein the hydroturbine is fixedly mounted on the holder; the filter screen component which is cylindrical and can be driven by the hydroturbine to rotate around own axis is mounted on the holder; a filtered water outlet is formed in the filter screen component; the cleaning pipe located above the axis of the filter screen component is arranged in the filter screen component; water outlets all capable of jetting water in the pipe to the inner wall of the filter screen component are transversely formed in the cleaning pipe at intervals. The hydroturbine propelled microfilter is reasonable and compact in structure; the hydroturbine is capable of pushing the filter screen component to rotate around the own axis, and meanwhile, a high-pressure fluid can be input into the cleaning pipe; as a result, water returned by the hydroturbine can be effectively utilized and the utilization rate of the high-pressure water source for driving the hydroturbine is improved; besides, back washing can be completed at the same time of filtering; the filtering efficiency is high, the back washing is thorough and blockage can be avoided.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, and relates to a water turbine driven microfilter. 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 volume. When the water flows slow...
