Description

Technical Field

[0001] The utility model relates to the field of aeration equipment, in particular to wastewater aeration equipment with an anti-blocking mechanism. Background Art

[0002] The aeration disc is one of the common aeration devices. It is usually made of materials such as rubber, silicone or polymer, and has many small holes or pores. The aeration disc is connected to the air source to pass the gas into the wastewater through the holes. After the gas enters the wastewater, bubbles will form and float up, thereby providing oxygen and stirring effects, and promoting the biodegradation process in the wastewater. However, the wastewater contains suspended solid particles, such as soil, sediment, suspended matter, etc. If these particles enter the aeration disc, they will adhere to the surface of the aeration disc, block the pores, affect the passage and distribution of gas, and reduce the aeration effect.

[0003] For example, the utility model disclosed in the publication (announcement) number: CN220951431U discloses a wastewater aeration device with an anti-blocking mechanism. Its technical solution includes: a ventilation main pipe, a four-way pipe is provided at the bottom end of the ventilation main pipe, each end of the four-way pipe is connected to a ventilation branch pipe, a non-return mechanism is provided in the air inlet pipe, a cleaning brush is provided on the inner ring of the sprocket wheel, a support plate is provided on the top of the ventilation branch pipe, and a waterproof motor is provided on the top surface of the support plate. By providing a non-return mechanism, the utility model can prevent wastewater from flowing back into the aeration disk, prevent particles and dirt in the wastewater from entering the aeration disk, reduce the blockage of the aeration disk by bubbles, keep the aeration disk unobstructed, and can clean the surface of the aeration disk regularly or at any time to scrape off the dirt and biofilm attached to the aeration disk, reduce the occurrence of bubble blockage, and improve the reliability and stability of the equipment. At the same time, it reduces the workload of manual intervention and cleaning, and improves the efficiency of the wastewater treatment system.

[0004] The equipment structure of the above-mentioned utility model is complex. Its anti-blocking mechanism drives the meshing transmission of the sprocket chain through the motor drive to enable the cleaning brush to clean the surface of the aeration disk. However, the sprocket chain is immersed in water for a long time, which will cause its surface to rust and affect its use. At the same time, the brush can only clean the surface of the aeration disk, and impurities and other pollutants will still enter the interior of the aeration disk through the holes of the aeration disk. Utility Model Content

[0008] Preferably, a mounting sleeve is sleeved and fixed on the outer side of the rotating shaft, and connecting rods are fixedly connected to both sides of the mounting sleeve.

[0009] Preferably, the other two sides of the mounting sleeve along the horizontal direction perpendicular to the two connecting rods are respectively fixedly connected with cutting blades, and the two sides of each cutting blade are respectively arranged as cross-sectional blade-shaped structures.

[0010] Preferably, each of the cleaning components comprises a cleaning plate which is arranged to fit the inner side of the annular filter in the vertical direction, and the cleaning plate is fixedly connected to the end of the connecting rod which is away from the mounting sleeve at the center position of one end away from the annular filter.

[0011] Preferably, each cleaning plate is fixedly provided with a cleaning brush near the inner side of the annular filter.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model discloses an air inlet pipe connected to an air source at one end, and the air source conveys the air into the installation cover through the air inlet pipe, and forms bubbles through the air holes of the aeration plate and flows into the waste water to be treated. An annular filter is arranged on the top of the installation cover to isolate pollutants, and a top cover is arranged on the top of the annular filter, so that the airflow sprayed from the aeration plate can only be discharged from the filter holes of the surrounding annular filter.

At the same time, the mesh annular filter is arranged to block the airflow sprayed from the aeration plate, and prevent large bubbles from directly entering the aeration plate. The air bubbles formed by the installation sleeve are further improved by the waterproof motor driving the rotating shaft to rotate, so that the installation sleeve fixed on the outside of the rotating shaft can drive the two connecting rods to rotate, so that the cleaning plate and the cleaning brush fixedly connected to the inner side of the annular filter at one end of each connecting rod can clean the large particles of impurities attached to the surface of the annular filter to avoid clogging of the filter holes. At the same time, the two cutting blades arranged can cut the airflow ejected by the installation sleeve as the installation sleeve rotates, and can cut large bubbles into small bubbles, thereby further improving the oxygen dissolution efficiency.
