Energy-saving aeration system with speed regulation function and wide action range

Abstract

The invention relates to an energy-saving aeration system with a speed regulation function and a wide action range. The system comprises an aeration tank, wherein the aeration tank is provided with anaeration device. The aeration device comprises a drive mechanism and two aeration mechanisms. The drive mechanism comprises a first motor, a first driving shaft, a telescopic assembly, a movable plate, two sliding assemblies and two fixed rods. The aeration mechanism comprises an air inlet pipe, an aerator, a branch pipe, a plurality of nozzles and two air outlet pipes. The aerator is equipped with a speed regulation assembly, a first bevel gear, a rotating shaft, two bearings and two air guiding assemblies. The energy-saving aeration system with the speed regulation function and the wide action range drives the aerator to rotate and move by the drive mechanism, and changes the rotation range of the aerator, allows the aerator to act in various places in the aeration tank, and improves the purification range. Moreover, the rotation speed of the rotating shaft in the aeration mechanism can be automatically regulated according to the sewage treatment progress to adjust the quantity of generated bubbles and reduce energy consumption, so that the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an energy-saving aeration system with a speed regulating function and a wide range of action. Background technique [0002] Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen. In addition, aeration can prevent the suspended matter in the pool from sinking and strengthen the contact between organic matter in the pool and microorganisms and dissolved oxygen, so as to ensure that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen to achieve sewage purification. Purpose of processing. [0003] As an important part of the aeration system, the aerator mainly relies on the rotation of the impeller to inject external air into the sewage, but in the actual sewage treatment process, the sp...

Problems solved by technology

[0003] As an important part of the aeration system, the aerator mainly relies on the rotation of the impeller to inject external air into the sewage, but in the actual sewage treatment process, the speed of the impeller is fixed. As a result, the suspended solids in the sewage gradually decrease. At this time, in order to maintain the fixed speed of the impeller, the aerator will consume a lot of energy, which will lead to an increase in the cost of sewage treatment. Not only that, because the aerator is fixedly installed in the aeration tank , resulting in a limited purification range of the aerator, and the aerator cannot treat the sewage in a distant place (such as around the pool wall), which leads to a reduction in the practicability of the existing aeration system
