Water falling oxygen increasing device for aquaculture and fish tank filtering system

Abstract

The invention relates to the technical field of pet breeding, in particular to a water falling oxygen increasing device for aquaculture. The device comprises a first partition plate (D1), a second partition plate (D2) and water outlet pipes (CSG); micropores (WK) are formed in the periphery of the first partition plate (D1); the micropores (WK) are higher than a liquid flow channel; the center ofthe second partition plate (D2) is closed; the outer surfaces of the lower ends of the water outlet pipes (CSG) are connected with the upper surface of the second partition plate (D2), and the lower ends of pipe cavities of the water outlet pipes (CSG) are connected with the lower surface of the second partition plate (D2); and at least two water outlet pipes (CSG) are arranged. The invention further relates a fish tank filtering system. The water falling oxygen increasing device for aquaculture is connected to a water discharging position of the system. According to the device and the system,the beneficial effects that the oxygenation efficiency is high, the appearance is attractive, and the fish health is facilitated are achieved, and a new technical thought is provided.

Description

technical field [0001] The invention relates to the technical field of pet breeding, in particular to a silent fish tank water injection aerator. Background technique [0002] Maintaining the oxygen content of the water body is an important technical issue for aquaculture. Falling water oxygenation refers to the use of filtered water to hit the liquid surface of the fish tank when it returns, generating air bubbles and increasing the oxygen content in the water of the fish tank. The noise of falling water oxygenation is generally relatively loud, and water splashing is serious. [0003] CN201820355726.0 Silent fish tank water injection aerator provides a way to eliminate the noise of falling water aeration. Its products are commonly known as "water dumb" in the Chinese market, which can reduce the noise of falling water and eliminate splashing water. [0004] However, the CN201820355726.0 silent fish tank water injection aerator has the following technical defects. [000...

AI Technical Summary

Problems solved by technology

[0005] Technical defect 1. Bubbles do not exist long enough, and the oxygen dissolved in water is not sufficient

[0006] Technical defect 2. After the air bubbles grow larger in the river, relying on the impact of falling water to refine, the refinement of falling water impact is unstable, so there is room for improvement in air bubble refinement

[0007] Technical defect 3. The number of air bubbles overflowing from the bottom is large, and these air bubbles may be attached to the surface of the fish body floating in the fish tank, causing the fish to suffer from air bubble disease

[0008] Technical defect 4. The growth and residence time of bubbles depends on the impact of falling water, which is unstable
