Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an aeration device for treating wastewater. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. An aeration step is part of the wastewater treatment process. Aeration is the process of forcibly transferring oxygen from the air into the liquid, with the aim of obtaining sufficient dissolved oxygen to accelerate the oxidation and decomposition of organic matter in the wastewater.

[0003] Existing aeration devices typically use a water pump to filter wastewater through a filter screen before it enters a water tank. Air and water are then mixed by agitator blades and ejected at high speed through nozzles to form a high-speed jet. However, after prolonged use, the filter screen can become clogged, affecting the device's long-term performance. Therefore, we need to upgrade and modify the existing technology.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 As shown in Figure 5, this embodiment provides an aeration device for treating sewage, including a device body 1, a protective shell 2 inside the device body 1, a motor 3 above the protective shell 2 and a mounting base 7 on the outer wall of the protective shell 2, a connecting rod 4 below the motor 3, a stirring blade 5 below the connecting rod 4, a fixing post 8 screwed into the mounting base 7 and an extension rod 6 connected to the front end of the mounting base 7, a sleeve 9 at the front end of the extension rod 6, a suspended ball 10 inserted into the sleeve 9, a screw hole 11 in both the suspended ball 10 and the sleeve 9, a threaded post 12 screwed into the screw hole 11, a water tank 15 connected below the extension rod 6, a pump 16 on the side of the water tank 15, a water pump pipe 17 connected to the front end of the pump 16 and an inlet pipe 18 connected to the rear end of the pump 16, a filter screen 20 inside the water pump pipe 17, and a mounting buckle 21 on the filter screen 20.

[0018] Preferably, a fixing bracket 31 is fixedly mounted on the motor 3, and the fixing bracket 31 is fixedly connected to the outer wall of the protective shell 2. By setting the fixing bracket 31, the stability of the motor 3 is increased and the safety of the motor 3 during use is ensured. There are three sets of threaded columns 12, and a knob 13 is fixedly mounted on one end of each threaded column 12. Each knob 13 has an anti-slip groove 14. By setting the knob 13, it is convenient for the user to adjust the pre-tightening of the threaded column 12. By setting the anti-slip groove 14, it is possible to prevent the user from slipping or having difficulty turning the knob 13 during the process of turning it.

[0019] Preferably, high-pressure nozzles 19 are fixedly installed on the outer wall of the water tank 15. Multiple sets of high-pressure nozzles 19 are provided. By installing high-pressure nozzles 19, the aerated water in the water tank 15 can be sprayed, increasing the usability and convenience of the device. The water pumping pipe 17 has an installation groove 22, and an installation buckle 21 is provided in the installation groove 22. By setting the installation groove 22 and the installation buckle 21, the filter screen 20 can be installed, which is convenient for the user to position the filter screen 20 and saves the time of searching for the device during installation. The installation groove 22 and the installation buckle 21 have positioning holes 23, and positioning posts 24 are inserted into the positioning holes 23. The positioning posts 24, the installation groove 22 and the installation buckle 21 all have screw holes 25, and bolts 26 are screwed into the screw holes 25. By setting the positioning posts 24 and the bolts 26, the device can be installed and fixed, ensuring the safety of the device during use, and facilitating the user to disassemble and maintain the device later, thus improving the flexibility of the device.

[0020] The working principle and operation process of this utility model are as follows: First, place the device in a wastewater tank. Control the pump 16 to filter the wastewater through the filter screen 20 of the pumping pipe 17 and then into the inlet pipe 18. From there, the wastewater enters the water tank 15. Control the motor 3 to run, which drives the connecting rod 4 to rotate. The rotating connecting rod 4 drives the stirring blade 5 to stir the water in the water tank 15. During the stirring process, the wastewater and air mix rapidly, and the repeated contact between the wastewater and oxygen generates bubbles. Then, add the cleaning agent to the water tank 15 for mixing. During this mixing process, the wastewater is treated. The treated water is then sprayed from the high-pressure nozzle 19 to form a high-pressure water jet. When the filter screen 20 needs to be disassembled and replaced, the user rotates the bolts 26 through the screw holes 25 to remove them. After removal, the user pulls the positioning pin 24 out of the positioning hole 23. Then, the user removes the filter screen 20 from the mounting slot 22 using the mounting clip 21. After unloading, the new filter screen 20 can be re-fixed. This allows for the installation and removal of the filter screen 20, facilitating future maintenance and replacement by the user, extending the lifespan and stability of the device, and ensuring aeration effect. When the suspended ball 10 needs to be disassembled and replaced after prolonged use, the user can use the knob 13 to rotate the threaded column 12 from the screw hole 11 to remove it. After removal, the suspended ball 10 can be separated from the sleeve 9 for replacement. Alternatively, the fixing column 8 can be removed from the mounting base 7 to replace the extension rod 6. The suspended ball 10 and the bracket can be disassembled and installed separately without the need for large-scale disassembly and reassembly of the entire device, reducing workload and working time, lowering maintenance costs, and improving the flexibility of the device.
