Problems solved by technology

But this device air inlet 7 is straight-through type, and 4 air inlets 7 vertical throat pipes 6 are arranged, and 4 air inlets 7 are distributed successively at intervals of 90°, specifically as Image 6 As shown, the cross-sectional area of ​​the air intake hole 7 is much larger than the original cross-sectional area of ​​the throat pipe 6, which is equivalent to forming a diffusion section at the air intake hole 7, and the liquid flow rate decreases, resulting in too small negative pressure formed, making it difficult for the outside air to It is efficiently sucked into the microbubble generating device, which reduces the oxygenation effect, and even makes the water flow overflow through the air inlet 7, so

Example Embodiment

[0026] Combine below Figure 1 to Figure 4 The specific structure of the self-pressure suction, oxygen, and water discharge pipe in the first embodiment of the present invention will be described in detail.

[0027] in Figure 1 to Figure 4 The self-pressure suction and oxygenation and discharge pipe shown in the first embodiment of the present invention includes a water inlet section 2, a contraction section 3, a throat pipe 4, an aeration and aeration section 10 and an elbow 9, and the front end of the water inlet section 2 There is a screw port 1 for connecting the high-pressure water pipe; the inner diameter of the constricted section 3 gradually decreases along the water flow direction, and its length is the same as the inner diameter of the throat pipe 4; the upper end of the throat pipe 4 near the aeration and oxygenation section 10 has a longitudinal section An arc-shaped suction chamber 7 is connected to an intake pipe 6 at the upper part of the suction chamber 7. The ...

Abstract

The invention relates to a self-pressed suction oxygen-aeration blow-off pipe which comprises a water inlet section (2), a contraction section (3), a throat tube (4), an air-entraining oxygen-aeration section (10) and a bend (9), wherein the bend (9) is connected to the tail end of the air-entraining oxygen-aeration section (10); an air suction cavity (7) of which the longitudinal section is arc-shaped is formed in the upper part, which is close to one end of the bend (9), of the throat tube (4); the cross sectional area of the air suction cavity (7) is gradually reduced from the exterior to the interior; an opening in the bottom of the air suction cavity (7) faces one side of a nozzle (10); the upper part of the air suction cavity (7) is connected with an air inlet tube (6); a vibrating plate (8) is fixed in the bend (9); and the vibrating plate (8) generates high-frequency vibration under water flow impact so as to break air bubbles, and the formed micro bubbles are dissolved in water so as to realize oxygen aeration. The self-pressed suction oxygen-aeration blow-off pipe is convenient to operate and maintain, low in construction cost and capable of stably and continuously increasing oxygen content in water, and has wide market prospects.

Description

technical field [0001] The invention relates to the technical field of modern agriculture, in particular to a self-pressurized air-breathing oxygen-increasing and oxygen-increasing water-discharging pipe which can increase the oxygen content of irrigation water supply or breeding water supply. Background technique [0002] Studies have proved that the increase of oxygen content in irrigation water can activate microbial activities in the root zone and mineral transformation, promote the growth of adventitious roots, water and nutrient absorption, play a role in saving water, increasing production, reducing non-point source pollution and preventing soil salinization . Increasing the oxygen content in the water supply for aquaculture can promote the growth and development of aquaculture organisms, degrade COD and other harmful substances in the water, purify the water environment, and improve the efficiency of aquaculture. [0003] In agricultural planting, the development of...
