Embodiment Construction

[0012] Such as figure 1 As shown, the conical aerator is composed of a section of cylindrical round pipe 2, a section of gradually expanding truncated cone-shaped outer barrel 5 and a section of tapering truncated truncated outer barrel bottom 15, wherein the round pipe 2 and the outer barrel 5 pass through flange C , D (18, 19) connection, the water flows through the round pipe 2 (there is a flange A1 at the entrance of the pipe), and passes through an inverted hemispherical water distribution plate 3, which is installed on the round pipe 2 The junction with the outer barrel 5 is welded and fixed to flange D19. The water distribution plate 3 is covered with small holes, the diameter of the small holes is 10mm, the hole center spacing is 15mm, and the microporous aerator A4 is set at a height of 150mm from the bottom of the water distribution plate. The diameter of the micropores of the aerator A4 is 100 microns, and its diameter is determined by the amount of water and the requir...

Abstract

The present invention relates to the water treatment technology in aquaculture, and is especially one pure oxygen aerator for high-density fish culture. The aerator includes one section of cylindrical pipe, one section of gradually expanding truncated cone and one section of gradually reducing truncated cone bottom, which are connected successively to constitute one sealed container. Inside the container, there are one aeration unit connected to oxygen pipe and water draining pipe in the bottom stretching beyond the container. Inside the sealed container, oxygen can dissolved repeatedly without escape and this results in high oxygen solubility and low power consumption.

Description

Technical field [0001] The invention relates to the field of water treatment in aquaculture, in particular to a cone-type aerator that is suitable for high-density fish farming and uses pure oxygen to aerate water bodies. Background technique [0002] Oxygen enhancement is a key issue in aquaculture. There are many ways to increase oxygen in fish ponds, such as chemical methods and mechanical methods. The mechanical aeration method is divided into two types: inflatable aerator and aerator. The inflatable aerator uses an aerator, a blower and an air compressor to press oxygen or air into the diffuser set in the fish pond. In order to release fine air bubbles into the pool water for aeration and oxygenation. The method has simple equipment, convenient operation and low operating cost. The disadvantage is that a large number of bubbles roll during aeration, and feces, uneaten feed, etc. are also carried by the water flow to freely diffuse in the water, reducing the sedimentation eff...
