Embodiment Construction
[0016] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0017] like figure 1 The shown guide rod type liftable dissolving device includes an aeration frame 1, the aeration frame 1 is welded by stainless steel pipes, and a plurality of aerators are arranged on the aeration frame; according to different requirements , the aerator is a disc aerator or a tube aerator, figure 1 The aerator described in is a disc aerator 2.
[0018] The aeration frame 1 is connected to the air pipe 7 through the air connection pipe 10 and the flange 4, and the aeration frame 1 and the air connection pipe 10 are connected through the fixed guide rod 3; in order to improve the stability during lifting, t...

The invention relates to a guide rod type liftable air dissolving device which comprises an aeration frame that is formed by welding stainless steel pipes, and a plurality of aerators are arranged onthe aeration frame; the aeration frame is connected with the air pipe through an air connecting pipe; the aeration frame is connected with the air connecting pipe through a fixed guide rod; a fixed ring is arranged at the bottom of the air connecting pipe, is connected to a fixed rod arranged in the activated sludge tank in a sleeving manner, and is fixed with one end of a steel wire rope, and theother end of the steel wire rope is connected with an elevator. The whole frame structure is high in stability and not prone to deformation, and the service life is prolonged; due to the combinationof a plurality of aerators, the service area is larger, and the aerators can be lifted integrally during later equipment replacement and maintenance, so that maintenance is convenient and rapid, the elevator can be electrically and manually lifted, and safety and labor saving are achieved; during maintenance, a worker do not need to go into a pool, risks are reduced, and life safety is protected.
Description
technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a guide rod type liftable air-dissolving device. Background technique [0002] In the operation of the existing liftable aeration device, a single aerator is connected to the air branch pipe through a connecting pipe, and the service area is small. During installation and maintenance, it is necessary to remove the aerator to be overhauled together with the connecting pipe from the air branch pipe, and lift the aerator out of the water for maintenance and replacement. During this process, the loading and unloading speed is slow, and the connecting pipe is easily deformed during use, resulting in uneven aeration. [0003] Moreover, the existing activated sludge tank aeration device has weak stability, short service life, insufficient service area, and heavy post-maintenance workload, which poses certain dangers to maintenance personnel.
