Problems solved by technology

The nutrients needed by plant roots in hydroponics can be maintained by supplementing the nutrient solution, but the oxygen needed is difficult to supplement artificially
[0003] The following problems exist in the prior art. People often add air to the nutrient solution through an external oxygen pump to maintain a certain oxygen content in the nutrient solution. This method requires additional mechanical and electrical devices, which increases the cost of planting, and Difficult to implement in a three-dimensional multi-layer implant system

Embodiment 1

[0033] see figure 1 In this embodiment, an oxygenation device for improving the dissolved oxygen content of a nutrient solution in a hydroponic system includes a hollow support 1, the hollow support 1 is arranged as a cuboid, and the openings at the upper and lower ends of the hollow support 1 are arranged in a square shape. In other implementations In an example, it can be a cylindrical tube. The upper and lower covers of the hollow support 1 are provided with a top cover 2 and a base 3 that match the opening shape of the upper and lower ends of the hollow support 1. A deflector 10 is provided in the water inlet 4. The horizontal plane of the deflector 10 and the horizontal plane of the water inlet 4 are set at an angle α, and the range of the angle α is 0-65°. Preferably, the angle α is 15°. Specifically, the deflector The area of ​​10 is smaller than the area of ​​the water outlet 301. Preferably, the area of ​​the deflector 10 is larger or smaller than the area of ​​the wa...

Embodiment 2

[0037] see figure 1 , Figure 4 , Figure 5 This embodiment is an oxygenation device for increasing the dissolved oxygen in a nutrient solution in a hydroponic system. The structure of the oxygenation device in this implementation is basically similar to that of Embodiment 1, the only difference being that the movable automatic oxygenation device Including the rotating wheel 6, the rotating wheel 6 includes a rotating shaft 601 and a plurality of rotating blades 602, the rotating shaft 601 is perpendicular to the hollow support 1 and is arranged on the inner wall of the hollow support 1, and the hollow support 1 is located at The position fixing grooves at both ends of the rotating shaft 601, the top of the fixing groove extends along the height direction of the hollow support 1 to the opening of the hollow support 1, and the rotating shaft 601 is taken out along the fixing groove together with the rotating blade 602 for cleaning. The length direction of the rotating shaft 6...

Embodiment 3

[0040] see figure 1 , Figure 6 , Figure 7 This embodiment is an oxygenation device for increasing the dissolved oxygen content of a nutrient solution in a hydroponic system. The structure of the oxygenation device in this implementation is basically similar to that of Embodiment 1, the only difference being that the fixed automatic oxygenation device includes The grid plate 7, the grid plate 7 is perpendicular to the hollow support 1 and is arranged on the inner wall of the hollow support 1, and the grid plate 7 is provided with a plurality of drainage holes 701 along the vertical direction, and the plurality of drainage holes 701 are equidistantly distributed along the width and length direction of the grid plate 7, the flow direction of the drainage holes 701 is consistent with the flow direction of the hollow support 1, there is a gap between the adjacent drainage holes 701, the water inlet 4 The flow rate is greater than the flow rate of the drainage holes 701. In othe...

Abstract

The invention relates to the technical field of soilless culture, and especially relates to an oxygenating device for increasing the dissolved oxygen of a nutrient solution in a water culture system.The device comprises a hollow support, a top cover and a base are arranged on the upper cover and the lower cover of the hollow support, a water inlet is formed in the top cover, a water outlet is formed in the base, the water inlet, the hollow support and the water outlet are sequentially communicated, and an automatic aerator for increasing the contact area between liquid and air by taking liquid flow in the hollow support as power is embedded in the hollow support. The oxygenation device can be clamped in the middle of a pipeline, and fan blades, a rotating wheel, and a grid plate or a brush layer are arranged in the device, so that a nutrient solution is dispersed when flowing through the device, the contact area between the nutrient solution and air is increased, and the dissolved oxygen content of the nutrient solution is increased.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to an oxygenation device for increasing the dissolved oxygen content of a nutrient solution in a hydroponic system. Background technique [0002] Soilless culture, also known as nutrient solution cultivation, hydroponic cultivation, hydroponics, is a kind of cultivation that does not use natural soil, but uses nutrient solution containing essential elements for plant growth and development to provide nutrition, so that plants can normally complete the entire life cycle of cultivation. technology. Soilless cultivation breaks away from the limitation of the soil and greatly expands the space for agricultural production, allowing crops to be produced on barren land, with very broad development prospects. The output of hydroponics is much higher than that of traditional planting, and it saves fertilizer and water. It not only has good economic benefits, but also has obviou...
