Description

Technical Field

[0001] The utility model relates to the technical field of aeration equipment, in particular to a membrane type microporous aerator. Background Art

[0002] Aeration tanks are commonly used in municipal and industrial wastewater treatment, often equipped with aeration devices. Diaphragm microporous aerators are a well-established type of aeration device. These devices offer small bubbles, a large bubble area, uniform bubble diffusion, no pore blockage, and strong corrosion resistance.

[0003] Existing aerators have limited use cases. To use them, they must first lay pipes on the bottom of the pond and then install the aerator on the pipes. This makes them unusable in scenarios such as aquaculture, where easy disassembly is crucial. This can affect subsequent harvesting, or the pond bottom's characteristics can prevent the pipes from being laid, making them unusable.

[0004] Prior art (CN218931861U) discloses a microporous aerator comprising an air tube, a microporous aerator, and a support block. The microporous aerator is mounted at the top of the air tube, the support block is mounted internally at the top of the microporous aerator, a diffusion mechanism is mounted at the top of the microporous aerator, and a cleaning mechanism is mounted on the outer wall of the top of the diffusion mechanism. This microporous aerator achieves the goal of increasing the aeration range through the coordinated operation of the rotating rod, fan, rotating block, fixed block, and fan blades in the diffusion mechanism. However, to use this aerator, a pipeline must be laid underwater and then the aerator must be installed on the pipeline.

These channels 123 include a first air segment 1231 and a second air segment 1232. The first air segment 1231 is connected to the air inlet 124 and is a straight line extending along the diameter of the disc rack 100. The second air segment 1232 is a semicircular arc with a diameter greater than half the radius of the disc rack 100. This results in more uniform aeration. The air channels 123 of this embodiment are provided on the support disc 121. Furthermore, the top surface of the support disc 121 of this embodiment is spherical.

[0048] In summary, the embodiment of the present invention provides a diaphragm 200 type microporous aerator, which is provided by setting a mounting hole 410 on the disc frame 100, and the support tube 300 is detachably mounted on the mounting seat 400. The support tube 300 supports the disc frame 100 and the diaphragm 200, so that the disc frame 100 and the diaphragm 200 are a certain distance away from the bottom of the pool. Then, a hose is connected to the air inlet 124, and the hose is connected to the air supply port on the shore, so that air can be supplied to the aerator for aeration. When fishing is needed, the connecting hose can be directly removed and the diaphragm 200 type microporous aerator can be removed, and the aeration location can be quickly switched according to actual needs. The support tube 300 ensures that the disc frame 100 and the diaphragm 200 are at a certain distance from the bottom of the pool, which can avoid the problem of gas transmission obstruction caused by the diaphragm 200 being reversed or pressing the hose. After the support tube 300 is disassembled, the aerator can also be used on the pipeline laid on the bottom of the pool. Therefore, the aerator of this embodiment has a wider range of application scenarios.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
