High-position water source drip-irrigation gravity turbine desilting filter system

Abstract

The invention relates to a high-position water source drip-irrigation gravity turbine desilting filter system. The system comprises an approach channel, an annular desilting filter tank, a sand accumulation and discharge tank, a clean water tank and laminated filter systems, wherein a front end inlet of the approach channel is connected with the sand accumulation and discharge tank through a coarse filter screen; the approach channel is provided with a water inlet gate, and the tail end is provided with an approach channel transition section; the approach channel transition section communicates with the desilting filter tank; a primary five-stage filter screen set, a secondary five-stage filter screen set, a tertiary five-stage filter screen set, a quaternary five-stage filter screen set and a quinary five-stage filter screen set are sequentially arranged in the desilting filter tank; the inner wall of the desilting filter tank is provided with an overflow filter screen, and connected with the clean water tank; the bottom of the clean water tank is respectively provided with two clean water tank water outlets and one clean water tank sand outlet; the two clean water tank water outlets are respectively connected with the two laminated filter systems; and the two laminated filter systems are connected with a micro irrigation system through an outlet pressure maintaining valve. The system has the advantages of low operating cost and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural water-saving irrigation filtering equipment, in particular to a high-level water source drip irrigation gravity turbine sand sedimentation filtering system. Background technique [0002] The filtration system is an indispensable water purification treatment equipment for the micro-irrigation system, which is directly related to the normal operation of the micro-irrigation system and the service life of the system. With the continuous progress of energy-saving technology, reducing operating costs and developing automatic cleaning and filtering devices with a high degree of automation have become the main direction of research and development of filtering equipment in various countries in the world. In recent years, with the rapid development of modern agriculture, the laminated self-flushing filters produced in Israel, Spain and other countries have been widely used in micro-irrigation systems...

Problems solved by technology

In recent years, with the rapid development of modern agriculture, the laminated self-rinsing filters produced in Israel, Spain and other countries have been widely used in micro-irrigation systems. The cleaning of the filters can be completed during the operation of the system, which is more convenient and has a high degree of automation. High, but due to the high price of the equipment itself and the need to place it in a dedicated management room, the input cost is virtually increased, which greatly restricts the development of agriculture
