Problems solved by technology

[0002] Water and fertilizer integrated irrigation as the current main irrigation method can solve the problem of water and fertilizer waste, but there are many impurities in the irrigation water, especially in the groundwater in mountainous areas. There are a lot of sand and gravel. There are a lot of algae, and these impurities will cause blockage of fertilization and irrigation pipes, resulting in crop water shortage and fertilizer shortage, resulting in huge economic losses

Abstract

The invention discloses an irrigation water source filtering device which comprises a gravel filter, a centrifugal filter and a screen filter which are serially connected through a pipeline. A first solenoid valve is arranged at an inlet of the pipeline, a second solenoid valve and a third solenoid valve are arranged at an inlet and an outlet of the gravel filter, a back flushing water inlet pipe is parallelly arranged between the second solenoid valve and the third solenoid valve, a fourth solenoid valve is arranged on the back flushing water inlet pipe, a filtering plate is arranged in the gravel filter, a back flushing water outlet pipe is arranged above the filtering plate, an electric valve is mounted on the back flushing water outlet pipe, a water storage tank is connected between the first solenoid valve and the second solenoid valve through a fifth solenoid valve, a sixth solenoid valve and a seventh solenoid valve are arranged at an inlet and an outlet of the centrifugal filter, and a ninth solenoid valve is arranged at an outlet of the pipeline. According to the invention, the defects in the prior art are avoided, irrigation water can be effectively filtered, and economic loss of agricultural irrigation caused by impurities in the irrigation water is reduced.

Description

technical field [0001] The invention relates to an irrigation device for agriculture and forestry, in particular to an irrigation water source filtering device and a control method thereof. Background technique [0002] Water and fertilizer integrated irrigation as the current main irrigation method can solve the problem of water and fertilizer waste, but there are many impurities in the irrigation water, especially in the groundwater in mountainous areas. There are a lot of sand and gravel. There is a large amount of algae, and these impurities will cause blockage of fertilization and irrigation pipes, resulting in water and fertilizer shortages for crops, resulting in huge economic losses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an irrigation water source filtering device and its control method, which can solve the deficiencies of the prior art, can effectively filter irrigation water, and reduce the ec...
