Anti-blocking drip irrigation filtering system

Abstract

The invention relates to a filtering device for farmland irrigation, and discloses an anti-blocking drip irrigation filtering system. The anti-blocking drip irrigation filtering system comprises a first-stage filter and a second-stage filter which are connected in series; each filter comprises a tank body and a filtering screen; the upper end of the tank body of each filter is provided with a water outlet, and the lower end of the tank body of each filter is provided with a water inlet. The anti-blocking drip irrigation filtering system is characterized in that the first-stage filter comprises at least one filter, and is internally provided with filter screens; the second-stage filter comprises at least two filters and is internally provided with filter screens and filter elements, and the filter elements are installed in the filtering screens, and are quartz sand filter elements; the filter screens and the water outlets of the tank bodies are connected. The anti-blocking drip irrigation filtering system can effectively prevent sediment in water from blocking a valve and a drip irrigation belt, and can be widely applied to irrigation of crops.

Description

technical field [0001] The invention relates to the technical field of farmland irrigation, in particular to an anti-clogging drip irrigation filter system. Background technique [0002] my country is a big agricultural country, and it is also a big country that lacks water, especially in the arid areas of the central and western regions. This also forces us to adopt drip irrigation technology more and more in agricultural production. Many drip irrigation waters carry sediment and sediment. It will block the valve and the drip irrigation belt. Therefore, a simple cyclone desander is often used at the head of the drip irrigation belt to simply treat the drip irrigation water. This method is simple, but this cyclone desander can only Part of the sediment in the water is removed, but the treated water is not clean enough, which can easily cause blockage of valves and drip irrigation belts, and also bring great inconvenience to people's work. Contents of the invention [0003] ...
