Aerating apparatus used for water oxygenation

Abstract

The invention provides an aerating apparatus used for water oxygenation and belongs to the technical field of aquatic organism. The aerating apparatus comprises an air supply total pipe, an aerating pipe (2) and an aerating pipe holder (1), wherein the air supply total pipe is provided with an air supply branch pipe, one end of the aerating pipe is closed and the other end of the aerating pipe is communicated with the air supply branch pipe by an air guide hose, and the aerating pipe holder is L-shaped or U-shaped, is hung at the top part of the wall of a water container, and is used for fixing the aerating pipe and stably disposing the aerating pipe below water; and a valve is arranged on the air supply branch pipe, and the aerating pipe is an aerating film pipe made of a flexible material and distributed with a plurality of high-density micro-pores. By adoption of the aerating apparatus provided by the invention, the aerating pipe when in a failure is restored or exchanged only by lifting the aerating pipe holder (1), without changing the water, and without affecting the normal work of other aerating pipes when being restored or exchanged. The aerating apparatus not only has the advantages of simple structure, low cost and convenience and rapidness in use, but also has significant economic benefit, and can be widely used for aquaculture and wastewater treatment fields as well.

Description

[0001] technical field [0002] The invention belongs to the technical field of sewage treatment and aquaculture, and in particular relates to an aeration device for increasing oxygen in water bodies. Background technique [0003] The aeration devices used in traditional sewage treatment and aquaculture are divided into blast aeration, surface aeration, submersible jet aeration and submerged aeration. At present, blast aeration is the most widely used, and its aeration The air diffusion device of the system, that is, the aerator is fixedly arranged at the bottom of the water body container. The aerator is usually a rigid air distribution tube with a microporous membrane fixed on the outside. Among them, usually multi-section air distribution pipes are connected by rigid pipes to form a group, and the rigid connection pipes are fixed to the bottom of the aeration tank through pipe clips, and usually the pipe clips are fixed to the bottom of the tank through bolt connections....

Problems solved by technology

But this technology also has the following problems: one is that the aeration tube used is an expandable and contractible hose, which is expensive and expensive, and is not easy to promote; the other is textile printing and dyeing, chemical medicine and papermaking, etc. The sewage in the industry is highly corrosive, and the pull rope is easily corroded and broken. Once the pull rope breaks, the water container must be emptied when the aeration pipe is replaced. It is corroded and broken. Once the pipe card breaks, the aeration pipe will float on the water surface of the treatment tank, and the aeration effect will not be achieved; the third is that the conne
