Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a liftable aeration device. Background Art

[0002] During the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool comes into contact with the air and is oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, prevent suspended objects in the pool from sinking, strengthen the contact between organic matter in the pool and microorganisms and dissolved oxygen, and oxidize and decompose the organic matter in the sewage. This process of forced oxygenation in the sewage is called aeration.

[0003] At present, most aeration devices are evenly and fixedly installed on the air duct, with an aeration plate set below at a relatively fixed height. When the aeration plate is blocked or damaged and needs to be replaced, if the sewage treatment tank is working normally, the aeration plate and the connected duct need to be removed for maintenance, which is difficult to operate. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a liftable aeration device that has a simple structure and is easy to operate.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A liftable aeration device comprises an air guide pipe arranged above a sewage treatment tank, the air guide pipe being evenly provided with air outlets, the air outlets being connected to aeration plates via hoses, the air guide pipe being evenly provided with mounting platforms, the lifting mechanisms on the mounting platforms being respectively connected to the aeration plates, the aeration plates being provided with guide plates, the air guide pipe being vertically provided with guide rods, and the guide plates being slidably provided on the guide rods.

[0007] When in use, the lifting mechanism drives the aeration plate to be raised and lowered, and the setting of the hose and guide plate can ensure the vertical movement of the aeration plate, so that the aeration plate can be operated at different heights. It has a wide range of uses and effectively improves the aeration efficiency. At the same time, when the aeration plate needs to be repaired and replaced, it can be lifted to the highest point for maintenance, which is less difficult to operate than direct disassembly.

[0008] As an optimization, the lifting mechanism includes a winding roller arranged on the mounting platform, the winding roller is transmission-connected to the drive motor, a rope is wound around the winding roller, a yield hole is provided on the mounting platform, the free end of the rope is fixedly connected to the guide plate, and the lifting mechanism is provided with two groups.

[0009] In this way, the guide plate and the aeration disc can be raised and lowered evenly and stably, and the lifting height can be accurately controlled to ensure the aeration quality.

[0010] As an optimization, the top of the guide rod is installed on the air guide pipe through a first clamp, and the bottom is fixedly installed on the bottom of the sewage treatment tank.

[0011] In this way, the guide rod can be installed stably and the aeration plate will not shake during the lifting process.

[0012] As an optimization, the mounting platform is fixedly mounted on the air duct via a second clamp.

[0013] In this way, the mounting platform can be stably installed, and if the lifting mechanism thereon fails, it can be removed for repair and maintenance.

[0014] As an optimization, each of the hoses is provided with a valve.

[0015] In this way, when carrying out maintenance, the corresponding valves can be closed individually without affecting the overall aeration work of the sewage treatment tank.

[0016] In summary, the liftable aeration device has the advantages of simple structure and easy operation. BRIEF DESCRIPTION OF THE DRAWINGS
