Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments.

As shown in figures 1 to 3, the novel recyclable aeroponics device is composed of a liquid supply system, a sprinkling irrigation system and a liquid return system, and realizes the recycling of nutrient liquid. The liquid supply system mainly comprises a liquid supply barrel 1, a main switch valve 2, a liquid supply pipeline 3, a water pump 4 and a timer 5; the sprinkling irrigation system mainly comprises a planting bucket 7, a planting cup 12, a spray head 13 and a shunt switch valve 14; the liquid return system mainly comprises a liquid discharge pipeline 8, a liquid return pipeline 9, a liquid return barrel 10 and a submersible pump 11. Wherein, supply bucket 1 provides the nutrient solution to planting bucket 7 through feed liquor pipeline 3 and water pump 4, and feed liquor bucket 1 is connected to 3 one ends of feed liquor pipeline, and the other end extends to planting bucket 7 top to be located and install shower nozzle 13 on the feed liquor pipeline 3 of planting 7 bung holes tops of bucket, shower nozzle 13 extends downwards to planting in the bucket 7, and plant cup 12 and be located around shower nozzle 13, the below of planting bucket 7 is equipped with the leakage fluid dram, and this leakage fluid dram is connected to through flowing back pipeline 8 return liquid bucket 10, is equipped with immersible pump 11 in returning liquid bucket 10, immersible pump 11's delivery port is connected to supply bucket 1 through returning liquid pipeline 9.

The working process of each system is as follows:

a liquid supply system: a white barrel with one ton capacity is used as a liquid supply barrel 1, prepared nutrient liquid is placed in the white barrel, and the nutrient liquid is transferred to a sprinkling irrigation system through a water pump 4. Because the nutrient solution is easy to have impurities, gauze can be added at two ends of a water pipe connecting the liquid supply barrel 1 and the water pump 4 for simple filtration. Furthermore, we connect the pump 4 to a timer 5 to control the time interval of the sprinkler irrigation, rather than to operate continuously.

The sprinkling irrigation system comprises: the liquid supply system and two rows of planting barrels are connected through a PVC pipeline, five round holes are uniformly formed in one circle of the barrel cover of each planting barrel 7 for placing the planting cups 12, space is saved, and the 360-degree spray head capable of uniformly spraying nutrient solution to root systems of plants in the five planting cups is arranged in the center. The branch switch valves are arranged on the pipelines between the spray heads and the liquid supply pipeline, and one branch switch valve correspondingly controls one corresponding spray head, so that the spray heads can partially work when unnecessary. And the lower end of the black planting barrel 7 is connected with a pipeline so as to discharge the residual nutrient solution to a liquid return system. In addition, in order to reduce the difficulty of liquid return, the ground column direction is designed to be slightly inclined.

A liquid return system: the liquid returning barrel 10 has the same specification as the liquid supply barrel 1, and in order to enable the nutrient solution to smoothly return from the planting barrel 7, the liquid returning barrel 10 is arranged underground to form a potential difference so as to prevent the nutrient solution from being accumulated in the planting barrel. A submersible pump 11 with a floating ball is arranged at the bottom of the liquid return barrel 10, and when the nutrient solution is accumulated to a certain height, the submersible pump 11 can automatically work to draw part of the nutrient solution back to the liquid supply barrel 1 to complete the circulation of the nutrient solution.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the scope of the present invention in any way, and all technical solutions obtained by using equivalent substitution modes and the like fall within the scope of the present invention.

The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
