Embodiment Construction

[0023] For better understanding and implementation, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] A jet aeration oxygen tank system includes a circulation aeration device, a pressurized water tank 15, a water storage tank 16 and a controller.

[0025] like figure 1 As shown, the water storage tank 16 is located under the pressurized water tank 15, and the two are sealed and separated and communicated through the water tank water guide valve 18. The circulating aeration device is communicated with the pressurized water tank 15 to continuously provide oxygen to the pressurized water tank 15. The water, circulating aeration device includes a PSA oxygen generator 22, and the PSA oxygen generator 22 is connected in series with a gas compressor 23 and a rotameter 25, and finally communicates with the suction port of the Venturi air jet device 28 through a one-way valve II 27, A pressure gauge I 24 is provided between...

Abstract

The invention relates to a jet flow aeration oxygen irrigation system. The system comprises a circulated aeration device, a pressure-bearing water box, a water storage box and a controller; the water storage box is communicated with the pressure-bearing water box; the circulated aeration device is communicated with the pressure-bearing water box; the circulated aeration device consists of an oxygenator, an oxygen diffuser and an air ejector; the oxygenator and the oxygen diffuser are connected with the controller. Compared with the prior art, the jet flow aeration oxygen irrigation system has the following advantages: secondary aeration is conducted through combination of a Venturi air ejector device and the oxygen diffuser, the oxygen enriched property of the aerated water is improved, the fact that the prepared water and gas mixing body can maintain a stable dissolved oxygen level in the long-distance water conveying process is guaranteed, and application of oxygen-adding irrigation in the field of surface irrigation such as flood irrigation, border irrigation and furrow irrigation is realized; different valve switches are provided, so that the system also can realize the functions of water and fertilizer coupled irrigation without adding oxygen and oxygen-adding water, fertilizer and gas coupled irrigation with single-time aeration and multi-time aeration.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a jet aeration oxygen irrigation system. Background technique [0002] With the development of modern agriculture, water-saving irrigation technology has been continuously promoted, and the current water resource utilization efficiency is constantly improving. Water and fertilizer utilization efficiency, the current research on water-fertilizer-gas integrated devices mainly focuses on the oxygenation of underground drip irrigation, and the device for surface irrigation oxygenation is almost blank, which is mainly limited by the efficiency of oxygenation; in addition, the current water-fertilizer-gas integration The chemical device mainly focuses on the design of the oxygen increasing function, and seldom involves the level of automation. [0003] With the improvement of research level, the continuous development of aerobic irrigation technology, the improvement of energy s...
