Problems solved by technology
[0005] When the above-mentioned secondary venturi tube is in use, it is necessary to ensure that the opening of the second valve is smaller than the opening of the fifth valve, which consumes the water head of the drip irrigation system of 3m to 5m and increases the operating cost of the drip irrigation system; at the same time, the secondary venturi The pipe is sensitive to the liquid flow and pressure changes of the main pipeline during use, which is not conducive to the precise control of irrigation indicators (such as irrigation time); at the same time, when the prior art controls the blockage of the emitter, the process of adding acid and chlorine Asynchronous, can not guarantee the effectiveness of adding chlorine to the greatest extent, reducing the effectiveness of acid / chlorination method to control system blockage

Abstract
The invention discloses a system and a method for preventing blockage of drip irrigation emitters, belonging to the field of irrigation. The system includes: a water pump, a main pipe connecting the water inlet port with the water pump outlet. The system also includes: a mixer, an acid storage tank, a chlorine storage tank, a first metering pump, and a second metering pump; the mixer is arranged at On the main pipeline, it includes: the first mixing tube and the second mixing tube connected in sequence according to the direction of water flow, and both the first mixing tube and the second mixing tube include: a conical tapered section and an equal-diameter section connected in sequence according to the direction of water flow , conical gradual expansion section; the inlet and outlet of the first metering pump are communicated with the water inlet of the acid storage tank and the first mixing pipe respectively; the inlet and outlet of the second metering pump are respectively connected with the chlorine storage tank and the second mixing pipe The water inlet is connected. The system for preventing clogging of drip irrigation emitters provided by the present invention can not only realize precise control of irrigation indicators, but also effectively prevent clogging of drip irrigation emitters and reduce operating costs.
Description
technical field [0001] The invention relates to the field of irrigation, in particular to a system and method for preventing blockage of drip irrigation emitters. Background technique [0002] At present, the use of drip irrigation system to irrigate farmland has been widely used to solve the problems of agricultural water shortage and low utilization rate of water and fertilizer. Since the irrigation water contains solid particles, algae, chemical ions, microorganisms and other impurities, and these impurities are easy to block the drip irrigation emitter in the drip irrigation system, it is not conducive to irrigation. Therefore, it is very necessary to provide a system for preventing the clogging of drip irrigation emitters. [0003] The prior art provides a system for preventing blockage of drip irrigation emitters. The system includes: a water pump, a main pipeline, a first branch pipeline, a second branch pipeline, a third branch pipeline, a secondary Venturi tube, a ...
