Aeration equipment for rice field crayfish cultivation

Abstract

The invention relates to aeration equipment for rice field crayfish cultivation. The aeration equipment comprises a control processor and an aeration mechanism and is characterized in that the controlprocessor is arranged in an equipment tank, the control processor is connected with an air compressor and an air pump, and the aeration mechanism is arranged on lateral beams and a middle beam and comprises an aeration pipe, a threaded cover, a support plate, a first aeration propeller, a second aeration propeller, a middle shaft, aeration holes, a cylinder barrel and aeration channels. The aeration equipment has the advantages that the aeration equipment is simple in structure, compressed air is blown into a rice field through the air compressor and the air pump, the three-blade aeration propellers are used, the aeration holes are formed in the same side of each blade of each aeration propeller, one oblique aeration hole is formed in the end of each blade of each aeration propeller, theaeration propellers are driven to rotate under the effect of pressure to further increase oxygen dissolving speed, oxygen dissolving efficiency is increased evidently, the aeration propellers are driven through the weak air pressure, aquaculture products and the rice soil base layer can be prevented from being destroyed, and the aeration equipment is reasonable and practical.

Description

technical field [0001] The invention relates to the field of aquatic product cultivation, in particular to an aeration device for raising shrimp in paddy fields. Background technique [0002] Aeration equipment is widely used in aquaculture, mainly to increase the oxygen content in water to ensure that aquatic products will not be hypoxic, and at the same time, it can also inhibit the growth of anaerobic bacteria in water and prevent the deterioration of pool water from threatening the living environment of aquatic products. The existing oxygenation methods include the following two types: one is the air pump type oxygenation method, which uses the air pump to pump air into the water to increase the dissolved oxygen in the water; the other is the paddle wheel tumbling type oxygenation method, which uses the paddle wheel Rolling the water at the bottom makes the water at the bottom rise and come into contact with the air, thereby increasing the amount of dissolved oxygen.

Problems solved by technology

The existing oxygenation methods include the following two types: one is the air pump type oxygenation method, which uses the air pump to pump air into the water to increase the dissolved oxygen in the water; the other is the paddle wheel tumbling type oxygenation method, which uses the paddle wheel Rolling the water at the bottom makes the water at the bottom rise and come into contact with the air, thereby increasing the amount of dissolved oxygen. Shrimp and aquatic products are cultivated in paddy fields, and the tumbling paddle wheel rotates faster. Using paddle wheel to increase oxygen will damage aquatic products to a certain extent. At the same time, the water quality in the paddy field is more turbid, and it has certain damage to the base soil of the paddy field, which affects the growth of rice. Therefore, it is not suitable to use the tumbling paddle wheel for oxygenation in the paddy field. The disadvantage of the existing technology is: the air pump oxygenation After the air enters the bottom of the water, the air overflows from the pipe, and the air floats naturally due to its small weight. The contact time between the air and the pool water is short, and the oxygenation effect is poor.
