Description

Technical Field

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

[0002] Wastewater treatment is a crucial link in environmental protection, vital for maintaining the ecological balance of water resources, safeguarding human health, and promoting sustainable development. Aeration, as one of the core processes in wastewater treatment, primarily functions to introduce sufficient oxygen into the wastewater, providing a favorable living environment for microorganisms in activated sludge. This enables them to efficiently decompose and remove organic pollutants, nitrogen, phosphorus, and other nutrients from the wastewater. While existing wastewater treatment aeration devices generally meet daily usage needs, some shortcomings still require improvement.

[0003] Most commercially available wastewater treatment aeration devices use aeration nozzles installed in an aeration tank to aerate the wastewater, providing sufficient dissolved oxygen to the activated sludge and thus decomposing harmful substances. However, in actual use, wastewater often contains insoluble precipitates that tend to adhere to the inside of the tank, requiring regular cleaning. Existing aeration tanks require considerable time and cumbersome disassembly of the top for cleaning. Therefore, we propose an aeration device for wastewater treatment to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an aeration device for wastewater treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aeration device for sewage treatment, comprising an aeration tank and an inlet and an outlet disposed on the aeration tank. An aeration chamber is provided at the bottom of the aeration tank. An air pump is installed on the right side of the aeration tank. Two sets of disc aeration heads are installed at the upper end of the aeration chamber. The air pump and the disc aeration heads are both connected to the interior of the aeration chamber. A top cover is provided at the top of the aeration tank. A stirring motor is installed in the middle of the top of the top cover. A stirring head is installed at the output end of the stirring motor. A fixing seat is fixed to the outside of the top cover. Guide rails are installed on both the front and rear sides of the aeration tank. Guide slides are installed in both sets of guide rails. Two sets of hydraulic lifting rods are installed on each guide slide. The output ends of the hydraulic lifting rods are connected to the bottom of the fixing seat. Linear actuators are installed at opposite ends of both sets of guide rails. The output ends of both sets of linear actuators are connected to the outer wall of the guide slides via connecting brackets.

[0006] As a further preferred embodiment of this technical solution, the input terminals of the air pump, stirring motor, hydraulic lifting rod, and linear actuator are all electrically connected to an external controller via wires.

[0007] As a further preferred embodiment of this technical solution, a sealing ring is adhesively bonded to the inner wall of the top cover.

[0008] As a further preferred embodiment of this technical solution, the outer surface of the stirring head is polished.

[0009] As a further preferred embodiment of this technical solution, both sets of disc aerators are connected to the interior of the aeration chamber via pipes, and the two sets of disc aerators are placed symmetrically along the axis of the aeration tank.

[0010] As a further preferred embodiment of this technical solution, the outer wall of the guide slide block is fully fitted with the inner wall of the guide slide rail, and the guide slide block and the guide slide rail are slidably connected.

[0011] This utility model provides an aeration device for sewage treatment, which has the following beneficial effects:

[0012] This invention features a movable top cover installed on the top of the aeration tank. A stirring motor drives the stirring head to rotate, agitating the wastewater inside the tank. When cleaning is required, four hydraulic lifting rods raise the top cover, and two linear actuators push the connecting bracket to the right. Two guide slides, under the action of the connecting bracket, move the top cover along the guide rail to the right, allowing workers to use hoses and other tools to rinse the inside of the aeration tank from above. This facilitates quick and easy cleaning of the tank's interior and maintenance of the stirring head, eliminating the need for extensive disassembly of the entire aeration tank. This significantly reduces the difficulty of cleaning the tank's interior and improves the ease of use. Attached Figure Description

If the specific posture changes, the directional indicator will also change accordingly.

[0020] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0021] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, an aeration device for sewage treatment includes an aeration tank 1 and an inlet 2 and an outlet 3 disposed on the aeration tank 1. An aeration chamber 4 is disposed at the bottom of the aeration tank 1. An air pump 5 is installed on the right side of the aeration tank 1. Two sets of disc aeration heads 6 are installed at the upper end of the aeration chamber 4. Both the air pump 5 and the disc aeration heads 6 are connected to the interior of the aeration chamber 4. A top cover 7 is disposed at the top of the aeration tank 1. A stirring motor 8 is installed at the center of the top of the top cover 7. A stirring agitator is installed at the output end of the stirring motor 8. The head 9 and top cover 7 are fixed with a fixed seat 10. The aeration tank 1 is equipped with guide rails 11 on both the front and rear sides. Guide slides 12 are installed in both guide rails 11. Two sets of hydraulic lifting rods 13 are installed on each guide slide 12. The output ends of the hydraulic lifting rods 13 are connected to the bottom of the fixed seat 10. Linear actuators 14 are installed at opposite ends of the two guide rails 11. The output ends of the two linear actuators 14 are connected to the outer wall of the guide slide 12 through the connecting bracket 15.

[0023] Two sets of disc aeration heads 6 are installed at the bottom of the aeration tank 1, allowing the air pump 5 to pressurize the aeration chamber 4 and the two sets of disc aeration heads 6 to discharge air from the aeration chamber 4. This ensures that the micropores on the disc aeration heads 6 can evenly aerate the wastewater. A movable top cover 7 is installed at the top of the aeration tank 1, which can activate the stirring motor 8 to rotate the stirring head 9, agitating the wastewater inside the aeration tank 1. This ensures sufficient movement of the wastewater inside the aeration tank 1, allowing the activated sludge in the wastewater to decompose harmful substances. When cleaning of the aeration tank 1 is required, the hydraulic lift on the guide slide 12 can be activated. The lifting rods 13 allow the four sets of hydraulic lifting rods 13 to lift the top cover 7 upwards. When the top cover 7 and the stirring head 9 are completely removed from the aeration tank 1, the two sets of linear actuators 14 can push the connecting bracket 15 to move to the right. Under the action of the connecting bracket 15, the two sets of guide slides 12 can move the top cover 7 to the right along the guide slide rail 11, allowing the top cover 7 to leave the top of the aeration tank 1. Then, the staff can use water pipes and other tools to rinse the inside of the aeration tank 1 from above, which facilitates quick cleaning of the inside of the aeration tank 1 and maintenance and cleaning of the stirring head 9. This effectively reduces the difficulty of cleaning the inside of the aeration tank 1 and improves the convenience of using the device.

[0024] In other embodiments, the input terminals of the air pump 5, the stirring motor 8, the hydraulic lifting rod 13, and the linear actuator 14 are all electrically connected to an external controller via wires.

[0025] This design allows an external controller to control the start and stop of the air pump 5, the stirring motor 8, the hydraulic lifting rod 13, and the linear actuator 14 in real time, ensuring that the air pump 5, the stirring motor 8, the hydraulic lifting rod 13, and the linear actuator 14 can be used normally for a long time.

[0026] In other embodiments, a sealing ring is adhesively bonded to the inner wall of the top cover 7;

[0027] This design effectively improves the sealing effect of the top cover 7 on the top of the aeration tank 1, thereby preventing sewage from seeping out from the top of the aeration tank 1.

[0028] In other embodiments, the outer surface of the stirring head 9 is polished;

[0029] This design effectively reduces the adhesion between the surface of the mixing head 9 and the condensate in the wastewater, thereby enabling rapid cleaning of the condensate on the surface of the mixing head 9.

[0030] In other embodiments, both sets of disc aerators 6 are connected to the interior of the aeration chamber 4 through pipes, and the two sets of disc aerators 6 are placed symmetrically along the axis of the aeration tank 1.

[0031] This design allows the air pump 5 to pressurize the inside of the aeration chamber 4, enabling the two sets of disc aeration heads 6 to provide stable aeration through the pipes of the aeration chamber 4.

[0032] In other embodiments, the outer wall of the guide slide 12 is fully fitted with the inner wall of the guide slide rail 11, and the guide slide 12 and the guide slide rail 11 are slidably connected.

[0033] With this design, when the linear actuator 14 drives the guide slide 12 to move laterally along the guide slide rail 11 via the connecting bracket 15, it can effectively prevent the guide slide 12 from shaking significantly during the movement, and can effectively ensure the stability of the guide slide 12 when it drives the top cover 7 to move.

[0034] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
