Problems solved by technology

Aquatic products must be equipped with an oxygenation system to ensure that live fish will not die during transportation. There are many ways to add oxygen to the water. One is to directly flush air into the water so that the air dissolves in the water to increase the oxygen content in the water. Although the cost of this method is low, the effect is not obvious enough, because the oxygen content in the air is limited, and the air bubbles will directly rush out of the water surface and the contact area with the water is limited; The method increases the oxygen content in the water, but the reaction of the oxygen enhancer in the water is too fast, and the maximum dissolved oxygen in the water is low, so it is necessary to add the oxygen enhancer several times, which still cannot solve the problem of oxygen deficiency in the water.

Embodiment 1

[0020] like Figure 1-2 As shown, a self-moving aeration equipment for aquatic product cultivation includes a disc-shaped housing 1 filled with a catalyst 2, and the catalyst is MnO 2 , the lower end of the housing 1 is fixedly connected with an airbag 3, the airbag 3 is an elastic rubber airbag with good deformability, and the airbag 3 is filled with an oxygen-making liquid, specifically, the oxygen-making liquid is H 2 o 2 , Catalyst 2 is MnO 2 , capable of catalyzing H 2 o 2 The following reaction occurs: 2H 2 o 2 =2H 2 O+O 2 ↑, the side wall of the airbag 3 is provided with a one-way valve 4 communicating with the outside. The one-way valve 4 can only allow outside water to enter the airbag 3. The airbag 3 communicates with the inside of the housing 1 through the one-way tube 5. The one-way tube 5. Only the liquid in the airbag 3 is allowed to enter the housing 1. The overall density of the device is slightly higher than that of water, and it can sink slowly in the...

Embodiment 2

[0026] like image 3 As shown, the difference between this embodiment and Embodiment 1 is that a plurality of air holes 8 are arranged on the side wall of one side of the fan blade 6, and the plurality of air holes 8 are arranged in an equidistant array. 7 are connected.

[0027] When the fan blade 6 rotates, a local low-pressure area is generated on the back of the fan blade 6, which forms a large pressure difference with the inside of the exhaust passage 7, so that the oxygen in the exhaust passage 7 can quickly pass through the air hole 8, and at this time, the air discharged from the air hole 8 Oxygen bubbles will be hit and scattered by the next rotating fan blade 6, which increases the contact area between oxygen and water, improves the dissolution rate of oxygen in water, and further improves the utilization rate of oxygen.

Abstract

The invention belongs to the technical field of transportation of aquatic products, and particularly relates to self-propelled aeration equipment for breeding of aquatic products, comprising a disc-shaped casing filled with a catalyst. The lower end of the casing is fixedly connected with an air bag filled with oxygen generation solution; a check valve communicated with the external is arranged onthe side wall of the air bag, and the air bag is communicated with the inside of the casing through an unidirectional pipe; a plurality of blades are fixedly connected to the side wall of the casing,and are arranged in a circular array; and exhaust pipes communicated with the inside of the casing are arranged in the blades respectively. In application of the self-propelled aeration equipment forbreeding of aquatic products, catalysis reaction can be performed in deep water to generate oxygen for the fish in water, and meanwhile, the oxygen generated can be ejected to drive the whole deviceto move in the water; further, oxygen can be distributed in the water uniformly, which is good for growth of fish; the device floats up and down to supply oxygen intermittently so that oxygen releaserate is reduced greatly and oxygen utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a self-moving aeration equipment for aquatic product aquaculture. Background technique [0002] There are many kinds of fish, which are often used as food or ornamental objects by people. Fish meat is rich in animal protein and phosphorus, rich in nutrition, delicious in taste, easy to be digested and absorbed by the human body, and plays an important role in the development of human physical strength and intelligence. Other parts of the fish body can be made into cod liver oil, isinglass, fish meal, etc., which have extremely high nutritional value. Some fish, such as goldfish and tropical fish, have various shapes and bright colors, have high ornamental value, and are deeply loved by most people. [0003] With the improvement of social level, in order to seek the freshest fish ingredients, people mostly choose live fish transportation when transporting aquatic...
