Injection type aerator

Abstract

The invention relates to improvement of an oxygen filling injection type aerator in water treatment. In order to overcome the technical problem of existing injection type aerator in connection of the air inlet tube and the water inlet tube, the invention provides an efficient injection type aerator which comprises a gas storage chamber, a power nozzle and an outer jet flow nozzle. The power nozzle and the outer jet flow nozzle are concentrically sleeved. A gas-liquid mixing chamber is formed between the power nozzle and the outer jet flow nozzle. An air inhaling hole is formed on the nozzle wall of the outer jet flow nozzle. The aerator is characterized in that the injection type aerator further comprises a gas inlet tube hoop fixed with the gas inlet tube and a water inlet tube hoop fixed with the water inlet tube. The gas inlet tube hoop and the water inlet tube hoop respectively consist of upper and lower clamping parts which are combined to form a cylindrical tube. The novel injection type aerator is reasonable in structure with remarkably improved performance, and can be widely applied to various water aerating operations.

Description

technical field [0001] The invention is an improvement to the aerator used for oxygenation in water treatment, and particularly relates to a high-efficiency jet aerator which is independent in structure, can be flexibly installed with an air supply pipe and a water supply pipe, and can significantly improve the performance of the aerator. Background technique [0002] There are mainly two types of aerators in the prior art, one is a circular disc jet aerator with multiple mixing nozzles around it, such as Chinese patents CN2700318, CN201447385U, CN201634512U, CN201908001U, etc.; a single mixing nozzle Jet aerators, such as Chinese patents CN2825632, CN101993145A, CN202121525U, etc. The above two types of jet aerators are basically connected with flanges when they are connected to the intake pipe and water inlet pipe. If a jet aerator is connected to an intake pipe and a water inlet pipe The operation is also relatively convenient, and the connection can be realized by insta...

Problems solved by technology

However, in practical applications, multiple jet aerators are installed on one air intake pipe and one water inlet pipe. If flange connection is used, multiple branch pipes need to be separated on the air intake pipe and water inlet pipe. The flange at the bottom is connected to the jet aerator, which undoubtedly increases the construction cost and also increases the technical requirements for installation and operation.
