Description

Technical Field

[0001] This utility model relates to the technical field of disc aerators, specifically to a disc aerator. Background Technology

[0002] Disc aerators are primarily used in aeration tanks of urban sewage and industrial wastewater treatment systems, and are considered key equipment in wastewater treatment. This equipment was developed and promoted by companies such as the German Jaeger Group, with Chinese manufacturers such as Wuxi Green Rhythm and Guangzhou Green Leaf also participating in its production. Its core components include an EPDM rubber diaphragm, an ABS engineering plastic body, and a ring-shaped air distribution piping system, using threaded connections.

[0003] Chinese utility model patent CN209835774U discloses a disc aerator, including a top cover, a base, and a diaphragm. The top cover is a ring with internal threads and a flange facing inward at one end. The base is disc-shaped and threaded to the inside of the top cover. An air inlet pipe is fixedly disposed in the middle of the base on the side away from the flange. The air inlet pipe has external threads. The diaphragm is pressed between the flange and the base. The diaphragm has air holes with a diameter of 0.8 mm. When the diameter of the diaphragm is 215 mm, it has 5500 to 6500 holes. When the diameter of the diaphragm is 260 mm, it has 8500 to 9500 holes. When the diameter of the diaphragm is 330 mm, it has 11000 to 12000 holes. The diameter of the air vents on the diaphragm was changed from 1.2mm to 0.8mm, and the number was doubled, which can generate smaller bubbles when the aerator is working.

[0004] However, the following problems were found in the implementation of the above-mentioned solution: when aeration stops, liquid may flow back into the air distribution branch pipe and the aerator, causing blockage. Secondly, the above-mentioned solution cannot clean the impurities attached to the air inlet during use, requiring frequent maintenance by staff, which in turn requires a lot of time and effort. Summary of the Invention

[0005] This utility model proposes a disc aerator, which solves the problem in related technologies that when aeration stops, liquid may flow back into the air distribution branch pipe and the aerator, causing blockage. Secondly, the above solutions cannot clean the impurities attached to the air inlet during use, requiring frequent maintenance by staff, which in turn requires a lot of time and effort.

[0006] The technical solution of this utility model is as follows: A disc aerator, comprising:

[0007] Base;

[0008] A diaphragm disposed on the base;

[0009] The top cover is threaded onto the base;

[0010] A plastic disc disposed within a groove on the base;

[0011] Two plastic rods are symmetrically fixedly installed on the bottom wall of the inner side of the plastic disc, and the plastic rods are inserted into the limiting ring on the base;

[0012] A sealing disc is fitted together on the two plastic rods, and the sealing disc is located below the plastic disc;

[0013] And a scraping component disposed within the ribs on the base, wherein the scraping component is connected to the plastic rod.

[0014] Preferably, the scraping assembly includes a first scraping disc that is sleeved on both of the plastic rods, two I-beams are symmetrically fixedly installed at the bottom of the first scraping disc, and a second scraping disc is fixedly installed at the bottom of the two I-beams.

[0015] Preferably, the first scraping disc and the second scraping disc have a plurality of micro-circular holes arranged in a circular array.

[0016] Preferably, a T-shaped screw is inserted into the slot on the I-beam plate, and two T-shaped openings are symmetrically opened on the rib of the base. A screw is inserted into the inner side of the T-shaped opening, and the screw end is threadedly connected to the T-shaped screw.

[0017] Preferably, a plurality of annular reinforcing ribs of different sizes are fixedly installed on one side of the base.

[0018] Preferably, the diaphragm has multiple air outlets arranged in a circular array at its center.

[0019] Preferably, one side of the base has multiple guide grooves arranged in a circular array.

[0020] The working principle and beneficial effects of this utility model are as follows:

[0021] When aeration stops, the plastic rod will descend under its own weight and water pressure. The descending plastic rod will then drive the plastic disc, which will press the sealing disc to seal the air inlet on the base. This will prevent impurities in the water from entering the aerator when it is not working.

[0022] When the plastic rod rises or falls, it drives the scraping component to rise and fall synchronously, so that the scraping component can scrape and clean the inner wall of the air inlet of the base, thereby reducing the possibility of blockage at the air inlet and eliminating the need for frequent maintenance by staff.

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0035] Please see Figure 1 - Figure 7 A disc aerator, comprising:

[0036] Base 1;

[0037] The diaphragm 2 is mounted on the base 1;

[0038] The upper cover 3 is threadedly connected to the base 1;

[0039] A plastic disc 4 is set in a groove on the base 1;

[0040] Two plastic rods 5 are symmetrically fixedly installed on the inner bottom wall of the plastic disc 4, and the plastic rods 5 are inserted into the limiting ring on the base 1;

[0041] A sealing disc 6 is fitted together on two plastic rods 5, and the sealing disc 6 is located below the plastic disc 4;

[0042] And a scraping component 7 is provided in the rib on the base 1, and the scraping component 7 is connected to the plastic rod 5.

[0043] This utility model provides a disc aerator. When gas enters from the air inlet of the base 1, the gas pushes the sealing disc 6, and then the sealing disc 6 synchronously drives the plastic disc 4. This allows the sealing disc 6 and the plastic disc 4 to rise stably under the action of the plastic rod 5 and the limiting ring in the base 1. This allows the gas to enter the base 1 and the diaphragm 2 from between the limiting ring and the sealing disc 6. When aeration stops, the plastic rod 5 and the plastic disc 4 will descend under their own weight and water pressure. The descending plastic disc 4 will then press the sealing disc 6 to seal the air inlet on the base 1, thereby preventing impurities in the water from flowing back into the aerator. Furthermore, when the plastic rod 5 rises and falls, it will drive the scraping component 7 to rise and fall synchronously. This allows the scraping component 7 to scrape and clean the inner wall of the air inlet of the base 1, thereby reducing the possibility of blockage at the air inlet and eliminating the need for frequent maintenance by personnel.

[0044] Furthermore, the scraping assembly 7 includes a first scraping disc 71 that is commonly mounted on two plastic rods 5. Two I-beams 72 are symmetrically fixedly mounted on the bottom of the first scraping disc 71, and a second scraping disc 73 is commonly fixedly mounted on the bottom of the two I-beams 72.

[0045] Specifically, when gas enters through the air inlet of base 1, the gas pushes the second scraping disc 73 upward. The rising second scraping disc 73 then drives the first scraping disc 71 to rise synchronously via the I-beam plate 72. When aeration stops, the first scraping disc 71 and the second scraping disc 73 descend under their own gravity, thus enabling them to scrape and clean the inner wall of the air inlet of base 1. In addition, when the plastic rod 5 is raised or lowered, it also drives the first scraping disc 71 to rise or fall. The rising and falling first scraping disc 71 then drives the second scraping disc 73 via the I-beam plate 72, thereby scraping and cleaning the inner wall of the air inlet of base 1. This reduces the possibility of blockage at the air inlet and eliminates the need for frequent maintenance by personnel.

[0046] Furthermore, the first scraping disk 71 and the second scraping disk 73 are provided with a plurality of micro-circular holes in a circular array.

[0047] Specifically, through multiple micro-circular holes on the first scraping disk 71 and the second scraping disk 73, it is ensured that gas can enter the base 1 and the diaphragm 2 after passing through the first scraping disk 71 and the second scraping disk 73.

[0048] Furthermore, a number of annular reinforcing ribs 10 of different sizes are fixedly installed on one side of the base 1.

[0049] Specifically, the ring-shaped reinforcing rib 10 makes the aerator more stable during underwater aeration.

[0050] Furthermore, multiple air outlets 11 are sequentially arranged in a circular array at the center of the diaphragm 2.

[0051] Specifically, the air outlet 11 can ensure aeration efficiency and achieve a mixed flow effect.

[0052] Furthermore, a plurality of flow channels 12 are sequentially formed in a circular array on one side of the base 1.

[0053] Specifically, the flow channel 12 facilitates gas dispersion. Example

[0054] Based on Embodiment 1, in this embodiment: a T-shaped screw cylinder 8 is inserted into the strip-shaped opening on the I-beam plate 72, and two T-shaped openings are symmetrically opened on the rib of the base 1. A screw 9 is inserted into the inner side of the T-shaped opening, and the screw end of the screw 9 is threadedly connected to the T-shaped screw cylinder 8.

[0055] The technical solution provided in this embodiment is as follows: by manually inserting the screw 9 into the T-shaped opening and connecting the screw end of the screw 9 to the T-shaped screw cylinder 8, and then under the action of the strip opening on the I-beam plate 72, it can be ensured that the scraping component 7 is stably installed on the base 1, and the lifting process of the first scraping disc 71, the I-beam plate 72 and the second scraping disc 73 will not be affected.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
