Filtering and purifying system for drip irrigation equipment

Abstract

The invention belongs to the technical field of drip irrigation equipment purifying devices and particularly relates to a filtering and purifying system for drip irrigation equipment. The filtering and purifying system comprises an anti-scale stacked filter, a cyclone dust collector, a water inlet pipe, a telescopic water inlet, a four-way valve, a blow-off pipe, a circulating pump, a circulating pump valve and a main water outlet pipe, wherein the telescopic water inlet is arranged at an inlet of the cyclone dust collector, and an outer pipe is connected with the main water inlet pipe; various ends of the four-way valve are connected with a water outlet of the cyclone dust collector, a water inlet of the anti-scale stacked filter, the circulating pump and the blow-off pipe separately; and a water outlet end of the circulating pump passes through the circulating pump valve to be connected with an inner pipe of the telescopic water inlet. Through the circulating pump device, the series stacked filter and cyclone dust collector can be at the optimum operating velocity, the equipment purifying efficiency is improved; and a cultivation structure and after-treatment structures of inactivation and ion exchange resin are arranged for the stacked filter device, so that low-cost water softening is achieved and the soil salinization possibility is reduced.

Description

Technical field: [0001] The invention belongs to the technical field of water purification devices for drip irrigation equipment, in particular to a filter and impurity removal device for drip irrigation water treatment. technical background: [0002] Drip irrigation is an irrigation method that drips water and nutrients needed by crops into the soil in the root zone of crops drop by drop through the pipeline system and the irrigator installed on the capillary according to the water requirements of the crops. Drip irrigation does not damage the soil structure, and the water, fertilizer, air, and heat in the soil are always kept in a good condition suitable for crop growth. The evaporation loss is small, there is no ground runoff, and there is almost no deep seepage. It is a water-saving irrigation method, suitable for Promote in areas that are not suitable for conventional irrigation methods such as water shortages and slopes. [0003] Due to the small size of the dripper i...

Problems solved by technology

[0003] Due to the small size of the dripper in the drip irrigation equipment, when the water flowing through the dripper belt contains particulate impurities, the dripper is easily blocked, causing the dripper to fail; therefore, the drip irrigation water needs to be filtered before pumping to prevent particulate matter from entering drip irrigation equipment

In the existing equipment, usually only the laminated filter is used for filtration, and there is still the possibility of calcium and magnesium ions in the water scaling and blocking the dripper. If the ion exchange resin is simply used to remove calcium and magnesium, it is easy to cause sodium, magnesium and...
