Saltwater-freshwater mixing irrigation equipment

Abstract

The invention belongs to the technical field of irrigation equipment, and particularly relates to saltwater-freshwater mixing irrigation equipment. The saltwater-freshwater mixing irrigation equipment comprises a saltwater storage tank, water desalting equipment, a pure water storage tank, a mixer and a buffer box, wherein the water outlet end of the buffer box is communicated with an irrigation pipeline through a pipeline; a stirring device is arranged in the mixer and comprises a rotary shaft which is vertically mounted in the mixer; a spiral blade which spirally extends around the rotary shaft is arranged on the rotary shaft; an anchor blade is arranged at the bottom of the rotary shaft; the shape of the anchor blade is matched with that of the conical bottom of the mixer. According to the saltwater-freshwater mixing irrigation equipment, saltwater and freshwater are mixed, so that the requirement on irrigation water is met, the salt content of the saltwater can be improved and reduced, the influence on the plant safety and the soil environment is smaller, and saltwater resources can be fully utilized.

Description

technical field [0001] The invention belongs to the technical field of irrigation equipment, in particular to a salty and fresh water mixed irrigation equipment. Background technique [0002] my country is a country with a shortage of water resources, and the distribution of water and land resources in our country is extremely unbalanced, and drought and water shortage are very serious in most areas. Soil salinization and shortage of fresh water resources are important factors restricting agricultural development in arid and semi-arid regions, and saline-alkali land is an important reserve cultivated land resource in my country, and its rational development is of great significance to ensure the safety of cultivated land in my country. The current saline-alkali land treatment methods mainly include hydraulic engineering measures combining wells, ditches, and canals; surface covering; application of chemical amendments; soil improvement and fertilization, and planting of salt...

AI Technical Summary

Problems solved by technology

In these areas, if the salt water is directly used for agricultural irrigation, the granular structure of the soil will be deteriorated, which will affect the air permeability and water retention performance of the soil.

At the same time, long-term use of salt water for irrigation will cause sub-salt biochemical in the soil, so that the crops cannot grow normally, or even wither

In addition, due to the limited fresh water resources, it is impossible to use fresh water for agricultural irrigation for a long time
