Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as Figure 1-2 As shown, the aeration equipment for aquaculture is set in the fish pond 1. The equipment includes a conical outer casing 2 arranged vertically at the bottom of the fish pond 1. The upper end of the outer casing 2 is open and the lower end is closed. And the upper end of the outer casing 2 does not exceed the water surface of the fish pond 1, the diameter of the upper end of the outer casing 2 becomes larger gradually to the diameter of the lower end, and the outer casing 2 is provided with the coaxial arrangement with the outer casing 2 through the pipe body positioning structure 3 and The inner casing 4 is conical, the diameter of the upper end of the inner casing 4 gradually decreases to the diameter of the lower end, an annular water outlet channel 5 is formed between the outer casing 2 and the inner cas...

The invention relates to an oxygenation device for aquaculture, which solves the problems of complex structure, slow oxygenation speed and poor effect of the existing oxygenation device. Which is arranged in a fish pond and comprises an outer sleeve, wherein the upper end of the outer sleeve is open and the lower end is closed; an inner sleeve is arranged in the outer sleeve; the inner sleeve isin a conical cylinder shape; an annular water outlet channel is arranged between the outer sleeve and the inner sleeve; the upper end of the inner sleeve is connected with a fish pond water replenishing pipe and / or gas conveying equipment; a foaming gap is formed between the lower end of the inner sleeve and the lower end of the outer sleeve; a radial shaft is arranged at the lower end of the outer sleeve; a foaming body is arranged on the radial shaft; and the foaming body respectively corresponds to the lower end of the inner casing respectively. The invention has the advantages of simple structure, ideal oxygenation effect, no influence on fish, flexible oxygenation of air and water, and the like.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aeration device for aquaculture. Background technique [0002] Aquaculture is an important field of agricultural and sideline industries. Chinese aquaculture, especially pond fish farming, is now at the forefront of the world in terms of total output, aquaculture area or average yield per unit of concentrated contiguous fish ponds. People use water to aquaculture better For aquatic products, it is necessary to always pay attention to the changes in the water quality in the fish pond, especially pay attention to the lack of oxygen in the water, which makes the existence of the oxygen increasing mechanism in the fish pond particularly important. The current aerators mainly have impeller-type structure and waterwheel-type structure. The impeller-type aerator drives the high-speed rotation of the impeller through the motor, and through the method of violent vibrati...
