Fish breeding box

Abstract

The invention discloses a fish breeding box. The box comprises a box body, a box water inlet and an overflow port are formed in the box body, and the box body water inlet and the overflow port are respectively connected with a water pipe and a discharging pipe; the water pipe is connected with a pond, the breeding box further comprises a solid-liquid separator, the discharging pipe is connected with a water inlet of the solid-liquid separator, and a water outlet of the solid-liquid separator is connected with the pond. According to the fish breeding box, pond water enters into the box body through the water pipe, a water level inside the box body reaches a certain level, the water inside the box body is discharged from the overflow port and passes through the solid-liquid separator and isdrained back to the pond, thereby forming a circulation; the pond is utilized as a buffer and water processing system, water environment quality inside the box body is ensured, the solid-liquid separator is utilized to separate larger solid particulate matters such as faeces and the like from the water inside the box body, thereby reducing the self-purification burden of the pond, the separated faeces can be recycled and used as ecological fertilizer for agricultural planting and the like, the whole breeding box is simple in structure and is applied to the field of fish breeding devices.

Description

technical field [0001] The invention relates to the field of fish breeding devices, in particular to a fish breeding box. Background technique [0002] At present, in the field of fish farming, some of them adopt box culture. Box farming is a method of assembling a box of a certain shape and specification with materials such as synthetic fibers or metals, and adding water to the box to raise fish. Box culture has the following advantages: 1. Fish are cultured in the box, with less activity and less energy consumption, which is conducive to the transformation and accumulation of nutrients; 2. It can avoid predatory fish and aquatic animals in the water area and improve the quality of life. Survival rate; 3. It is less affected by environmental factors such as terrain and weather; 4. It is easy to manage and has a high return rate. [0003] However, the existing breeding tanks have the following problems: 1. There is no water circulation in the tank, and the water quality is...

AI Technical Summary

Problems solved by technology

[0003] However, the existing breeding tanks have the following problems: 1. There is no water circulation in the tank, and the water quality is easy to drop. A purification system is installed in the tank, but it will occupy the breeding space and consume a lot of energy; 2. When the breeding water is discharged, it contains a lot of fish. Dirt like feces, increasing the purification pressure of the water environment
