High-pressure water mist ecological cultivation system

A high-pressure water mist ecological cultivation system, wherein the high-pressure water mist ecological cultivation system comprises:

• a nutrient solution supply system assembly, a cultivation rank assembly, and a nutrient solution back-flow system assembly, wherein the nutrient solution supply system assembly comprises a nutrient solution storage tank and pressurizes a nutrient solution from the nutrient solution storage tank and then delivers the nutrient solution to the cultivation rank assembly, the cultivation rank assembly plants and cultivates a crop seedling, and the nutrient solution back-flow system assembly recovers the nutrient solution that is not absorbed by the crop seedling for recycled use,
• wherein a solution outlet of a high-pressure pump set of the nutrient solution supply system assembly is provided with an overflow valve, and one overflow opening of the overflow valve is connected to the nutrient solution storage tank via a second duct, so as to form a loop, an other exit of the overflow valve is provided with a pressure gauge for observing a pressure, and the overflow valve and the pressure gauge are configured for unloading of the system and control of a pressure of the system, so as to ensure stability of pressure during operation of the system and achieve safety protection of the high-pressure pump set and
• wherein the cultivation rank assembly is provided with a plurality of cultivation ranks, a bottom of each of the plurality of cultivation ranks is provided with nutrient solution collection openings, the nutrient solution collection openings are respectively provided with corresponding nutrient solution back-flow ducts, each of the nutrient solution back-flow ducts is connected to a back-flow main duct, a nutrient solution collected by the back-flow main duct flows back to a nutrient solution back-flow tank of the nutrient solution back-flow system assembly, and the nutrient solution back-flow tank is connected to the nutrient solution storage tank, for recycled use of the nutrient solution collected by the back-flow main duct.
