Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration device capable of lifting an aerobic pool. Background Art

[0002] In the sewage treatment process, aeration can make the liquid in the pool contact with air for oxygenation, and can stir the liquid to accelerate the transfer of oxygen in the gas to the liquid, thus completing the oxygenation; in addition, aeration can also prevent the sedimentation of suspended matter in the pool, and help the mutual contact between organic matter and microorganisms and dissolved oxygen, ensuring that the microorganisms in the pool can oxidize and decompose organic matter in the sewage under the condition of sufficient dissolved oxygen. The quality of the aeration device not only affects the effect of sewage biochemical treatment, but also directly affects the land occupation, investment and operating costs of the treatment plant.

[0003] The mainstream aeration devices in existing sewage treatment are: one is to install disc aerators on the aeration main pipe and aeration branch pipe fixed to the bottom of the pool. This aeration device is troublesome to overhaul and replace in the later stage, and it is necessary to stop production and empty the pool, which is labor-intensive and affects the normal operation of the treatment system; the other is a liftable tubular aeration device, which requires a large number of horizontal pipes to be installed on the top of the pool. The tubular aerator is suspended and fixed on the horizontal pipe by flanges and branch pipes, and the flange installed on the upper part of the water surface can realize the lifting of the aeration device, but the layout of the horizontal pipe of the device is large, the number of liftable aeration units is large, and the installation and maintenance workload is large.

[0004] Therefore, we propose an aerobic pool with an elevating aeration device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an aeration device for an aerobic pool that can be lifted to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: an aerobic pool liftable aeration device, comprising: a pool body, two lifting devices are provided on the pool body, a tubular aerator is provided at the bottom of the pool body, the lifting device lifts the tubular aerator, and the tubular aerator is connected to the main pipe through a detachable aeration riser.

[0007] Preferably, the lifting device is mainly composed of a bracket and a lifting rope, and the lower end of the lifting rope is connected to the tubular aerator.

[0008] Preferably, the upper end of the pulling rope is connected to a manual or electric winding roller.

[0009] Preferably, the upper and lower ends of the detachable aeration standpipe are respectively provided with a positive thread joint and a reverse thread joint, the detachable aeration standpipe is connected to the tubular aerator via the reverse thread joint, and the detachable aeration standpipe is connected to the main pipe via the positive thread joint.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] It breaks through the traditional fixed aeration device on the bottom of the pool. It can solve problems in time without emptying the pool, effectively reducing the workload of aeration equipment inspection and maintenance in the sewage treatment system, and effectively ensuring the normal operation of the sewage treatment system. The device greatly reduces the workload of operation and maintenance personnel, reduces sewage treatment costs and improves treatment effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: an aerobic pool liftable aeration device, comprising: a pool body 1, two lifting devices 2 are arranged on the pool body 1, a tubular aerator 6 is arranged at the bottom of the pool body 1, the lifting device 2 lifts the tubular aerator 6, and the lifting device 2 is used to lift the tubular aerator 6 out of the pool body 1;

[0018] The lifting device 2 is mainly composed of a bracket and a lifting rope, and the lower end of the lifting rope is connected to the tubular aerator 6;

[0019] One end of the tubular aerator 6 is connected to a detachable aeration riser pipe 4, and the upper and lower ends of the detachable aeration riser pipe 4 are respectively provided with a positive thread joint 3 and a reverse thread joint 5. The aeration riser pipe 4 can be detached from the positive thread joint 3 and the reverse thread joint 5 by simply rotating the aeration riser pipe 4 in the same direction. At the same time, the tubular aerator 6 arranged at the bottom of the aeration tank is separated from the main pipe, and the tubular aerator 6 can be lifted out.

[0020] Working principle: Rotate the aeration vertical pipe 4 in the same direction to make it fall off from the positive and negative thread joints, and at the same time separate the tubular aerator 6 arranged at the bottom of the pool body 1 from the main pipe, and lift the tubular aerator 6 out of the water through the lifting device 2 arranged on the pool body 1, and repair and replace the damaged or blocked tubular aerator 6.
