Description

Technical Field

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

[0002] Wastewater aeration device is an important device used to provide oxygen in the sewage treatment process. It injects air into the wastewater to increase the dissolved oxygen content in the water, thereby supporting the growth and metabolic activities of microorganisms and promoting the decomposition and removal of organic matter in the wastewater. It is mostly used in water supply and drainage systems. Jet aerator is a type of aeration device. It achieves the purpose of aeration by mixing external oxygen with sewage and jets. It is widely used in wastewater treatment.

[0003] When the existing jet aerator is in use, the aerator is installed in a submersible manner. Since the bracket used for installation at the bottom of the aerator is a fixed structure, each time the installation is performed, it is necessary to ensure that the hole position is relatively fixed for normal installation. There is a limitation of poor fault tolerance during installation. In addition, in the jet aerator, no filtering structure is set inside the sewage inlet pipe, and impurities in the sewage can easily enter the aerator and cause blockage. In some jet aerators, a filter screen is set in the water inlet pipe. However, the filter screen is installed with screws, which is not convenient for disassembly and replacement, and cannot be installed quickly, and the flexibility of operation is poor.

[0018] When installing the aeration device, the device body 1 is placed in the wastewater treatment pool, supported by the support frame 4, and fixed by the installation structure 5. The device body 1 is provided with a water inlet structure 6 and a jet pipe 7. At the same time, an air inlet pipe 3 is installed on the device body 1 through the connecting pipe 2. When aeration is performed, after the device body 1 is started, the gas enters the device body 1 through the air inlet pipe 3 and the connecting pipe 2. At the same time, the sewage enters the device body 1 through the water inlet structure 6. The sewage inside the device body 1 is mixed with the external air and finally ejected through the jet pipe 7. In this way, the purpose of aerating the wastewater is achieved, thereby increasing the dissolved oxygen content in the water, thereby supporting the growth and metabolic activities of microorganisms, and promoting the decomposition and removal of organic matter in the wastewater.

[0019] Through the above implementation scheme, the mounting structure 5 includes a fixing block 501, a threaded rod 502, a mounting plate 503 and a connecting block 504, the fixing block 501 is fixedly connected to the threaded rod 502, and the fixing block 501 is installed on the support frame 4, the mounting plate 503 is connected to the connecting block 504, and the connecting block 504 is sleeved on the threaded rod 502, the mounting structure 5 also includes a circular hole 505, a nut 506 and a mounting hole 507, the circular hole 505 is opened on the connecting block 504, and the threaded rod 502 passes through The circular hole 505 and the nut 506 are connected to the upper end of the threaded rod 502, and the nut 506 contacts the connecting block 504. The mounting hole 507 is opened on the mounting plate 503. The mounting structure 5 is arranged on the support frame 4. The mounting plate 503 is rotatably mounted on the fixing block 501 through the connecting block 504 and the threaded rod 502. When installing the entire device, the mounting plate 503 can be rotated to make fine adjustments in position to ensure adaptability and flexibility during installation without affecting the fixing effect of the device.

[0020] When installing the device body 1, after supporting the device body 1 with the support frame 4, the connecting block 504 is mounted on the threaded rod 502 through the circular hole 505. At this time, the mounting plate 503 contacts the bottom of the wastewater treatment tank. The mounting plate 503 is rotated until the mounting hole 507 is aligned with the hole on the bottom of the tank. Then, the screw is passed through the mounting hole 507 to fix it. Finally, the nut 506 is screwed onto the threaded rod 502 so that the nut 506 is against the connecting block 504. In this way, the fixing work of the device body 1 is completed. After connecting the corresponding pipeline, aeration can be carried out.

[0021] According to the above implementation scheme, the water inlet structure 6 includes a water inlet pipe 601, a filter frame 604 and a fixed end 605, the filter frame 604 is arranged inside the water inlet pipe 601, the fixed end 605 is connected to the end of the water inlet pipe 601, and the water inlet structure 6 also includes a limiting protrusion 602, an internal thread 603, a threaded joint 606 and an anti-slip strip 607, the limiting protrusion 602 is fixed in the water inlet pipe 601, the internal thread 603 is opened in the water inlet pipe 601, the threaded joint 606 is fixed on the fixed end 605, and the threaded joint 606 is fixed to the fixed end 605. The head 606 is connected to the internal thread 603 in the water inlet pipe 601, the anti-slip strip 607 is fixed to the fixed end 605, and the water inlet structure 6 is adopted. A filter rack 604 is arranged inside the water inlet pipe 601, which can effectively filter impurities and prevent impurities from entering the device body 1 and causing blockage. The filter rack 604 is pressed and fixed with a threaded joint 606 to ensure stability in use. When the filter rack 604 is damaged, the threaded joint 606 and other structures can be quickly disassembled to facilitate replacement of the filter rack 604.

[0022] When setting the aeration device, after the device body 1 is fixed, the water inlet structure 6 is set, and the filter frame 604 is set inside the water inlet pipe 601, so that the filter frame 604 is against the limiting protrusion 602, and then the threaded joint 606 on the fixed end 605 is against the water inlet pipe 601, and the fixed end 605 is rotated through the anti-slip strip 607, so that the threaded joint 606 is screwed into the water inlet pipe 601 through the internal thread 603, until the threaded joint 606 presses the filter frame 604 on the limiting protrusion 602, so that the setting of the water inlet structure 6 is completed. During use, sewage enters the water inlet pipe 601 through the fixed end 605, and finally enters the device body 1. The filter frame 604 plays a role in filtering impurities. If the filter frame 604 needs to be cleaned or replaced, the fixed end 605 is rotated to remove the threaded joint 606, and the filter frame 604 is taken out for operation. After the operation is completed, it can be installed again for continued use.
