Anti-clogging capillary drip irrigation emitter with flat plate superimposition structure

Abstract

The invention discloses an anti-clogging capillary drip irrigation emitter with a flat plate superimposition structure. On basis of a physical phenomenon that water in a narrow slit rises up under the action of capillary force, at least two n-shaped flat plates are used to form a stable narrow slit to enable water in a container to move upwards and diffuse outside the container along the narrow slit, and then the balance between gravity of water and surface tension of the narrow slit to water is broken, as a result, the required drip irrigation speed is obtained, water is enabled to move from the inside of the container to the outside of the container at a low speed, and water-saving irrigation is performed on a targeted plant. The capillary force only works on water and has no effect on solids such as sandy soil, and meanwhile, the uninterrupted drip irrigation scheme is adopted, so that salt substances are diluted continuously to prevent salt accumulation; and further, a micro water delivery device is placed in a working environment insolated from sunlight, so that microbes are prevented from breeding. In this way, the capillary drip irrigation emitter can be prevented from being clogged by sandy soil, salt and microbes, and meanwhile, a super-large size drip irrigation system free from limitation of pressure attenuation can be constructed by utilizing the theory of communicating vessels.

Description

technical field [0001] The invention relates to a drip irrigation device, in particular to an anti-clogging capillary drip irrigation device with a flat plate superimposed structure, which can realize the function of running water from the inside of the container to the outside of the container at a slow speed to perform water-saving irrigation on target plants. Background technique [0002] In order to meet the needs of production and life in human society, various water conservancy irrigation projects have been invented. However, due to the increasing shortage of water resources, people are forced to adopt more economical irrigation methods. Water-saving irrigation in human society has made a significant contribution. [0003] Drip irrigation is to use a set of special equipment to filter the pressure water (which can be pressurized by the water pump or the pressure generated by the terrain drop), and then pass through the water delivery pipe network at all levels to th...
