Embodiment

[0012] Example: refer to figure 1 , an airless stone cultivation aeration device, which has an upper conical flow guide 12 and a lower conical flow guide 13 placed oppositely up and down; Near the center of the axis between the pipes 25 is provided with a water spray port 26; the water spray port 26 is dynamically connected with the water pump 2 through the oxygen-increasing water spray pipe 25; . The water nozzle 26 of the oxygen-increasing water spray pipe 25 is turned up and down as required, and the oxygen-containing water flow gushing out through the water nozzle 26 meets the upper and lower cone-shaped flow guides 13 and the upper cone-shaped flow guide 12 respectively, and the water tank 1 Three-dimensional oxygenation is carried out to make the upper and lower water flow in the water tank circulate, which has the functions of uniform oxygenation area, balanced oxygenation level, activating the water body and inhibiting the growth of anaerobic bacteria in the water.

Abstract

The invention discloses an air-free stone breeding oxygen-adding device. The air-free stone breeding oxygen-adding device is provided with an upper tapered flow guide part and a lower tapered flow guide part which are oppositely arranged in the vertical direction, wherein a water spraying port is arranged near the middle of the axis among the upper tapered flow guide part, the lower tapered flow guide part and an oxygen-adding water spraying pipe, the water spraying port is connected with a water pump in a movable matched mode through the oxygen-adding water spraying pipe, and the oxygen-adding water spraying pipe is connected with a motor through a traction wheel and a belt. The air-free stone breeding oxygen-adding device has the advantages that oxygen adding or sterilization operation is carried out on surface water and bottom water according to needs, and problem products can be destroyed under emergency situations.

Description

technical field [0001] The invention relates to a super-intensive aquaculture aeration equipment, in particular to an airless aquaculture aeration device. Background technique [0002] In aquaculture, dissolved oxygen is an important factor affecting the food intake, growth rate, feed coefficient and health status of fish and shrimp. According to relevant data, the feed coefficient of fish when dissolved oxygen is 3 mg / L is greater than that when it is 4 ppm Double, the growth rate of fish grown in dissolved oxygen 7ppm is 20%-30% faster than that of fish grown in dissolved oxygen 4PPm, while the bait coefficient is 30%-50% lower. When the dissolved oxygen in the water reaches above 4.5ppm, the appetite of the fish will be greatly enhanced. For this reason, my country's "Fishery Water Quality Standards" stipulates that the dissolved oxygen (DO) in aquaculture water must be kept at least 5mg / L for more than 16 hours in a 24-hour day, and should not be lower than 3mg / L at any...
