Oxygen supply device for fish culture

Abstract

The invention discloses an oxygen supply device for fish culture. The oxygen supply device for fish culture comprises an air supply through pipe, the input end of the top of the air supply through pipe fixedly communicates with an air pump, the output end of the bottom of the air supply through pipe fixedly communicates with a balance weight air injection ball, the middle position of the outer portion of the air supply through pipe is fixedly connected with a supporting baffle, a floating carrier plate is slidably connected to the outer portion of the air supply through pipe and located below the supporting baffle, waste collecting mechanisms are evenly and fixedly connected to the surface of the top of the floating carrier plate at equal intervals, guiding discharge outlets are formed in the positions, close to the two sides of the bottom, of the outer side of the balance weight air injection ball, an oxygen supply dispersing mechanism is fixedly connected to the middle position of the bottom end of the outer portion of the balance weight air injection ball, and auxiliary inserting needles are evenly and fixedly connected to the surface of the bottom of the supporting baffle at equal intervals. The invention relates to the technical field of fish culture. According to the oxygen supply device for fish culture, air bubbles are dispersed and refined, and the contact area between the air bubbles and culture liquid is increased.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to an oxygen supply device for fish farming. Background technique [0002] Fish breeding, rearing and stocking. Fish farming, also known as aquaculture, pisciculture and pisciculture, is important in maintaining food supplies, fishing and expanding fishing areas. [0003] For example, the Chinese invention publication number is: a kind of industrialized fish farming oxygen supply equipment of CN111328761A, including a controller, an oxygen pump and a culture pond, and the inside of the culture pond is provided with several vertical pipes distributed in an array, each vertical pipe Extending in the vertical direction, the upper end of each vertical pipe is equipped with an explosion disc, the lower end of each vertical pipe is connected with the outlet of the oxygen pump, and each vertical pipe is equipped with an electric flow regulating valve. An oxygen content sensor is als...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an oxygen supply device for fish farming, which solves the problem that the air pump is used to supply oxygen to the fish pond at present, and the air bubbles are filled into the culture solution from the bottom of the pond, and the air bubbles will fill the pond with oxygen. The sediment and fish feces deposited at the bottom are blown up, and the traditional oxygen supply device cannot filter and screen the blown feces, which will affect the breeding environment in the pond, and the traditional oxygen supply equipment cannot evenly disperse the air bubbles into the culture solution Conducive to the problem of fully dissolved oxygen in the culture solution
