Micro-nano circulating oxygenation and aeration equipment

Abstract

The invention discloses a micro-nano circulating aeration and aeration device, comprising a diving aeration device and a floating system, wherein the floating system comprises a fixing bracket, a sliding bracket, a driving mechanism and a rubber airbag, and the fixing bracket is provided with a guide rail. The sliding bracket is slidably sleeved on the rail and fixedly connected to the driving mechanism, and the diving aerator is mounted on the sliding bracket and moves on the rail by the driving mechanism, the rubber The airbag is fixed on the upper end of the fixing bracket to float the fixing bracket on the water surface to ensure that the diving aeration device is at a stable water depth. The floating system can control the submersible aeration device to work under a constant water depth, thereby controlling the inhalation noise within a desired range to avoid noise pollution, and the driving mechanism can drive the submersible aerator to move underwater and expand the aeration. The range makes the aeration effect better.

Description

Technical field [0001] The invention relates to the field of aeration equipment, in particular to a micro-nano cycle oxygen-increasing aeration equipment. Background technique [0002] In the sewage treatment process, certain methods and equipment are used to forcibly add air to the sewage, so that the sewage in the pond and the air are oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, and prevent the suspension of the pond from sinking , Strengthen the contact of organic matter in the pond with microorganisms and dissolved oxygen, and oxidize and decompose the organic matter in the sewage. This equipment for forced oxygen increase in the sewage is called aeration equipment. [0003] Chinese patent (application number: 201510328652.2) discloses an underwater positioning type aeration equipment, which is characterized in that the main structure includes a diving aerator, a floating support, a fixed support, a rubber inflatable float...

AI Technical Summary

Problems solved by technology

This underwater positioning aeration equipment can make the aerator work at a fixed water depth to adapt to changes in water depth, but the aerator cannot automatically move underwater, resulting in a narrow aeration range and poor aeration effect

[0004] Moreover, the shortcomings of traditional aerators cannot be overcome. For traditional aerators, due to the difference in air-water density, the lifting force will be generated, forming a strong driving force, and forming an ascending air-water mixed flow in a small area, so a large amount of investment is required. Most of the micro air bubbles in the work overflow from the water and are discharged into the atmosphere, resulting in poor aeration effect
