Energy-saving filtering device for agricultural drip irrigation water

Abstract

The invention discloses an energy-saving filtering device for agricultural drip irrigation water. The device comprises a water storage tank and a top plate, wherein the water storage tank and the topplate are spliced together, a transparent glass plate is arranged in the center of the top plate, a partition plate is fixedly connected into the water storage tank, and a piston plate is connected into the water storage tank in a sealed and sliding mode. According to the invention, raw water can be evaporated by means of photo-thermal energy contained in sunlight, and the evaporated water vapor is condensed to achieve distillation purification so as to remove impurities, acid-base property and salt contained in water, so that the filtering effect is achieved, it is avoided that the water is acidic or alkaline due to poor water quality when the raw water is directly irrigate, the adverse effects on growth of plants planted in a farmland water due to high salt content in a water body is avoided, the device is energy-saving, and reflected light can stably irradiate a substrate by adjusting the height of a reflecting ring and matching different sunlight incident angles in different time periods according to the outside air temperature.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an energy-saving filtering device for agricultural drip irrigation water. Background technique [0002] Drip irrigation uses plastic pipes to send water to the roots of crops through holes or drippers on capillaries with a diameter of about 10mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. It has been widely used in agricultural irrigation at this stage. [0003] However, during drip irrigation, since the water quality cannot be guaranteed, it is easy to affect the normal growth of planted crops due to the acidity or alkalinity of the water body and the high salinization of the water body, and the impurities contained in the water body can easily cause drip irrigation pipes The orifice or dripper of the upper capillary is blocked. Once blocked, t...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: but when drip irrigation is performed, the water quality cannot be guaranteed, so it is easy to affect the planting due to the acidity or alkalinity of the water body and the high salinization of the water body The normal growth of crops and the impurities contained in the water can easily cause the capillary orifice or dripper on the drip irrigation pipe to be blocked. Once blocked, the entire drip irrigation pipe cannot be used
