Solid dissolving and injecting system with circular flushing and accurate dissolution control functions

Abstract

The invention discloses a solid dissolving and injecting system with the circular flushing and accurate dissolution control functions. The solid dissolving and injecting system comprises a spray flushing and dissolving pond with the upper portion opened, a spray head is correspondingly arranged above an opening of the spray flushing and dissolving pond and is connected with a spray water supply pipeline, and a spray tank filtering net is laid in the spray flushing and dissolving pond and divides the spray flushing and dissolving pond into an upper spray flushing and dissolving pond body and a lower spray flushing and dissolving pond body; a dissolving solution collecting pond is arranged below the spray flushing and dissolving pond and is connected with a dissolving solution injecting pipeline, a spray flushing and dissolving pond outlet is formed in the bottom of the lower spray flushing and dissolving pond body, and the dissolving solution collecting pond is connected with the spray flushing and dissolving pond outlet. By means of the own hydrodynamic force of the head of an irrigation system, solid fertilizer (pesticide) is dissolved and injected, circular flushing and accurate control are achieved, and it is ensured that being dissolved thoroughly, the solid fertilizer or pesticide does not block a drip irrigation pipe.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilization, pesticide application and irrigation, and in particular relates to a solid dissolution injection system for circular flushing and precise control of dissolution. Background technique [0002] With the development of agricultural modernization, the water-fertilizer (pesticide) integration technology based on drip irrigation has been recognized in the vast rural areas. The water-fertilizer (pesticide) integration technology can realize water-saving irrigation and realize the comprehensive coordination and integrated management of water and nutrients. , has the advantages of improving crop yield and quality, strong adaptability to terrain and geology, and being able to maintain water and soil, and has become an important symbol of modern agriculture. However, at present, the dissolution of fertilizers (pesticides) is not complete or it is easy to cause clogging, which has been pla...

AI Technical Summary

Problems solved by technology

The disadvantage of using a mixer to stir the dissolved fertilizer (pesticide) is that the dissolved fertilizer (pesticide) solution needs clarification time by stirring, and it is often not clarified after the irrigation is over; There is a lot of waste residue in the pipeline, which is easy to block the filter at the head of the drip irrigation and the drip irrigation pipe at the end of the drip irrigation system

However, these fertilization devices all have shortcomings such as incomplete dissolution of solid fertilizer, large waste residues, and long time for fertilizer injection.
