Structure of suspension water-lifting aerator and usage method

Abstract

The present invention discloses a suspended type water lifting aerator, which is of a straight through tubular structure that consists of a floater, a gas liquid lifting tube, an aerator (or an aerator combination), a water lifting draft tube, a dropping device, and an air releasing tube, which are mutually connected. A compressed air enters the aerator (or aerator combination) through the air releasing tube to generate air marks. The water, around the aerator or in the internal clearances of the aerator combination, is mixed with the air and lifted in the gas liquid lifting tube along with the air marks, and flows out from a liquid outlet which is submerged below the surface of the water. The aerator (or the aerator combination) is smaller than the lifting tube and the draft tube connected therewith, and thus the upward communication and flow of the water is facilitated. The device is vertically suspended and arranged in water through the suspension of the floater and the pull-down of the dropping device so as to oxygenize the water at the bottom and lift the water at the lower layer. The adopted aerator is suspended and moveable, solves the problems that the aerator requires large air pressure and is inconvenient to mount and maintain, and the like, and can be widely applied to many fields, such as the disposal of various waste waters and sewages, aquiculture oxygen addition, and the like.

Description

(1) Technical field: [0001] The invention relates to a device and a method for gas and liquid mixed treatment, especially a device and a method for raising the lower layer of liquid upward, gas-entraining and dissolving, and mixing and stirring. The invention adopts a suspended and movable aeration device, which solves the problems that the aerator requires high air pressure and is inconvenient for installation and maintenance, and can be widely used in many fields such as various waste water and sewage treatment, aquaculture oxygenation, and the like. (two) background technology: [0002] At present, when gas-liquid mixing is performed in aquaculture, most motors are used to drive the impeller to rotate, and oxygenation is carried out by means of pushing water, spraying, adding air, rotating, compressing, and directly dragging. The structure is complex, the mechanical parts immersed in the water are easy to corrode, and the power is high, the energy consumption is high, and...
