Rotary aerator

Abstract

The invention discloses a rotary aerator. The aerator comprises a floating rack and an air pump, wherein the air pump is fixed on the floating rack, and the air outlet of the air pump is connected with an air outlet pipe; the aerator also comprises an air distributing pipe, and the air inlet end of the air distributing pipe is connected with the air outlet pipe through a rotary joint; the annular part of the air distributing pipe is connected with more than two main air supply pipes at intervals in the circumferential direction, and the free ends of the main air supply pipes are connected with air supply branch pipes extending downwards; the bottom of each air supply branch pipe is connected with a sprayer, and the sprayers of the air supply branch pipes jet airflow in the same rotation direction; the bottom of each the main air supply pipe is provided at intervals in the lengthwise direction with at least two air distributing branch pipes extending downwards, and at least one nano aerator pipe is connected between the two adjacent air distributing branch pipes. The rotary aerator has the advantages of integrating aeration, water stirring, oxygen increasing, wave making into one body, and being less in energy consumption and higher in oxygen aeration efficiency.

Description

Technical field [0001] The invention relates to the field of aerators, in particular to a rotary aerator. Background technique [0002] Since the beginning of the 21st century, the freshwater aquaculture industry has made considerable progress, which is both an opportunity and a challenge. Mechanized aquaculture is gradually being developed, which has qualitatively improved the output of domestic freshwater products. However, as the output of freshwater products increases and the upgrading of breeding equipment is promoted, farmers hope to improve the efficiency of freshwater aquaculture, hoping to increase the yield of aquaculture per mu. In this way, it is necessary to increase the stocking density per mu of water surface. As the density of fish fry increases, the small biosphere originally formed in the pond will be broken, and the natural bait in the fish pond will not be sufficient for the growth of the fish, and compound feed must be fed into the fish pond. When the farme...

Problems solved by technology

However, the functions of the above aerators, such as free single or stirring water, or making waves, or spraying water, all have problems such as high energy consumption, low efficiency, uneven water stirring on the upper and lower layers, etc.
