Description

Technical Field

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

[0002] In wastewater treatment, aeration is a common method. Utilizing the activated sludge process, air or oxygen is added to the water to increase dissolved oxygen concentration. A certain retention time is provided within the treatment tank to meet the oxygen requirements of aerobic microorganisms and ensure sufficient mixing between the wastewater and activated sludge, thereby promoting the degradation and removal of organic matter in the water. During this process, blowers are typically used to introduce gas into the tank; therefore, blowers play a crucial role in aeration-based wastewater treatment.

[0003] In existing aeration tanks, the blower is prone to clogging after prolonged operation, which increases the blower load, increases additional energy consumption, and reduces aeration efficiency, affecting the normal operation of the entire aeration tank. Utility Model Content

[0004] The purpose of this invention is to overcome the problem in the existing technology that the blower is prone to blockage after long-term operation, which leads to increased blower load, increased additional energy consumption, reduced aeration efficiency, and affects the normal operation of the entire aeration tank.

[0005] To achieve the above objectives, this utility model provides an aeration tank, comprising:

[0006] Pool body;

[0007] A blower assembly is located outside the tank and is used to introduce gas into the tank.

[0008] Anti-clogging component, the anti-clogging component is designed to strike the fan assembly to prevent the fan assembly from becoming blocked;

[0009] An anti-uniformity component, installed above the tank and extending into it to agitate the gas, ensures uniform dispersion of the gas introduced into the tank; and

[0010] The driving component can simultaneously drive the anti-clogging component and the anti-uniformity component.

[0011] In some embodiments, the anti-clogging component includes a striking rod disposed on the side near the blower assembly, and the anti-unevenness component includes a swing plate extending into the pool body. The striking rod and the swing plate can be driven by a drive assembly so that the striking rod strikes the blower assembly and the swing plate agitates in the pool body.

[0012] In some embodiments, the driving component includes: a driver;

[0013] An incomplete gear is a gear that can be driven to rotate by a driving component.

[0014] The rack intermittently meshes with the gear of the incomplete gear when the incomplete gear rotates, and moves linearly from an initial position to an end position when meshing with the incomplete gear. An anti-blocking component and an anti-uneven component are connected to the rack and can move synchronously with the rack. The rack also includes a first reset component that can drive the rack to move linearly from the end position to the initial position when it is not meshing with the incomplete gear.

[0015] In some embodiments, the drive assembly further includes a support plate, a rack slidably connected to the upper surface of the support plate, a first reset member being a first reset spring, the first reset spring being connected to one end of the rack along a direction parallel to the rack's movement, and the other end of the first reset spring being fixedly connected to the support plate.

[0016] In some embodiments, the anti-uniformity component further includes:

[0017] The movable rod is connected to the drive assembly. The swing plate includes a linkage part disposed above the pool body and a stirring part extending vertically downward into the pool body. The movable rod is disposed on one side of the swing plate at relatively intervals. The movable rod can move toward the linkage part under the drive of the drive assembly and push the swing plate from the initial position to the end position, or away from the swing plate.

[0018] Support members, two support members are disposed opposite each other at the top of the pool body in a direction perpendicular to the swing plate, and are slidably connected to both ends of the linkage; and,

[0019] The second reset member can drive the swing plate to reset from the end position to the initial position when the movable rod is driven away from the swing plate.

[0020] In some embodiments, the ends of the two opposing support members away from the movable rod are connected to a fixed plate parallel to the swing plate, and the second reset member is a second reset spring, which is connected between the fixed plate and the swing plate in a direction perpendicular to the swing plate.

[0021] In some embodiments, the fixed plate is connected to a guide rod that extends perpendicular to the swing plate and passes through the linkage and the movable rod, so that the guide rod can guide the movement direction of the swing plate and the movable rod.

[0022] In some embodiments, the support member includes a support plate disposed on the top of the pool body. The support plate has grooves recessed inward on opposite sides. The two ends of the swing plate are embedded in the grooves and can reciprocate within the grooves. Limiting plates are provided at both ends of the grooves to prevent the swing plate from sliding out of the grooves.

[0023] In some embodiments, the movable rod includes a rod body and a pressure rod. The rod body is parallel to the swing plate, and the pressure rod is connected to the side of the rod body facing the swing plate and extends toward the swing plate.

[0025] The above technical solution employs an anti-clogging component that strikes the blower assembly, causing vibration and loosening foreign objects adhering to the blower assembly's pipes. This facilitates airflow carrying away the foreign objects, preventing blockage caused by their accumulation, and ensuring a more stable gas flow into the tank, thus improving aeration efficiency. Simultaneously, the drive component activates both the anti-clogging and anti-uneven gas distribution components, ensuring uniform gas dispersion within the aeration tank and accelerating the reaction process. The combined effect of these two components significantly improves the overall aeration efficiency of the aeration tank. Attached Figure Description

[0035] In this invention, unless otherwise stated, directional terms such as "up," "down," "left," "right," "inner," and "outer" are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] To address the problem in existing aeration tanks where blowers easily become clogged after prolonged operation, leading to increased blower load, higher energy consumption, reduced aeration efficiency, and disruption of the entire aeration tank's normal operation, this invention provides an aeration tank, such as... Figures 1-2 As shown, the aeration tank includes: a tank body 1 with an opening at the top, containing wastewater to be treated; a blower assembly 2, located outside the tank body 1, used to introduce gas into the tank body 1 to promote the decomposition of organic matter in the wastewater by microorganisms within the tank, and can introduce air or oxygen as needed; an anti-clogging assembly 4, configured to strike the blower assembly 2 to prevent blockage and allow the blower assembly 2 to introduce gas into the tank body more stably; an anti-uneven distribution assembly 5, installed above the tank body 1 and extending into the tank body 1 to agitate, so that the gas introduced into the tank body 1 is evenly dispersed, improving aeration efficiency; and a drive assembly 6, which can simultaneously drive the anti-clogging assembly 4 and the anti-uneven distribution assembly 5, so that the anti-clogging assembly 4 strikes the blower assembly 2 while the anti-uneven distribution assembly 5 agitates within the tank body 1. Through the above technical solution, the anti-clogging component 4 strikes the blower component 2, causing the blower component 2 to vibrate. This loosens foreign objects attached to the pipes of the blower component 2, allowing the airflow to carry away the foreign objects and preventing blower blockage caused by foreign object accumulation. This results in a more stable gas supply to the tank, improving aeration efficiency. Simultaneously, the drive component 6 drives the anti-uneven distribution component 5, ensuring uniform gas dispersion within the aeration tank and accelerating the reaction process. The combination of these two components improves the overall aeration efficiency of the aeration tank.

[0037] In some embodiments, such as Figures 1-2As shown, the anti-clogging component 4 includes a striking rod 41 located near the blower component 2, and the drive component 6 can drive the striking rod 41 to strike the blower component 2. The anti-uneven aeration component 5 includes a swing plate 53 extending into the tank body 1, and the drive component 6 can drive the swing plate 53 to agitate it in the tank body 1. Therefore, when the blower component 2 introduces gas into the tank body 1, the striking rod 41 continuously strikes the blower component 2, keeping the pipes of the blower component 2 unobstructed, and at the same time agitating the swing plate 53 in the tank body 1, so that the gas introduced by the blower component 2 is evenly distributed in the tank body 1, and the aeration tank as a whole maintains a high aeration efficiency.

[0038] In some embodiments, such as Figures 1-2 As shown, the drive assembly 6 includes: a drive member 61, which can be a motor as in the prior art, used to provide power; an incomplete gear 62, which is connected to the output end of the drive member 61 and can be driven to rotate by the drive member 61; a rack 63, which can mesh with the gear of the incomplete gear 62. When the incomplete gear 62 rotates, the rack 63 meshes with the gear of the incomplete gear 62 intermittently, and moves linearly from the initial position to the end position when meshing with the incomplete gear 62; an anti-blocking component 4 and an anti-uniformity component 5 are connected to the rack 63 and can move linearly synchronously with the rack 63; and a first reset component, which can drive the rack 63 to move linearly from the end position to the initial position when the rack 63 is not meshing with the incomplete gear 62. Thus, through the intermittent meshing of rack 63 and incomplete gear 62, rack 63 reciprocates between the initial position and the final position. The striking rod 41 and the oscillating plate 53 also continuously strike the blower assembly 2 and agitate the pool 1 along with the reciprocating movement of rack 63. Specifically, when rack 63 meshes with incomplete gear 62, rack 63 moves from the initial position to the final position; when rack 63 is not meshed with incomplete gear 62, rack 63 moves from the final position to the initial position under the drive of the first reset member. Alternatively, the drive assembly 6 can be configured to connect the output end of drive member 61 to a lead screw, with a sleeve screwed onto the lead screw. The sleeve is connected to the anti-blocking component 4 and the anti-unevenness component 5. Drive member 61 drives the lead screw to rotate in different directions, and the sleeve reciprocates along the length of the lead screw, causing the striking rod 41 to continuously strike the blower assembly 2, and the oscillating plate 53 to agitate the pool 1.

[0039] In some embodiments, such as Figures 1-2As shown, the drive assembly 6 also includes a support plate 65, which provides support for the rack 63. The rack 63 is slidably connected to the upper surface of the support plate 65. The first reset element is a first reset spring 64, which is connected to one end of the rack 63 along a direction parallel to the movement of the rack 63. The other end of the first reset spring 64 is fixedly connected to the support plate 65. When the rack 63 meshes with the incomplete gear 62, the rack 63 slides away from the first reset spring 64, the first reset spring 64 is stretched, and the rack 63 moves from the initial position to the end position. When the rack 63 does not mesh with the incomplete gear 62, the first reset spring 64 uses its elastic force to move the rack 63 from the end position to the initial position. Figures 1-3 As shown, the drive component 61 is fixedly connected to the outer wall of the pool body 1, and a support column is also provided below the support plate 65 to support the entire drive device. A slide rail can be provided on the upper surface of the support plate 65, and the rack 63 slides along the slide rail, thereby slidably connecting to the upper surface of the support plate 65. Alternatively, a groove can be provided on the upper surface of the support plate 65, allowing the rack 63 to slide in the groove and guiding the movement direction of the rack 63. The first reset component can also be a cylinder, which replaces the first reset spring 64 and is connected to the rack 63. When the incomplete gear 62 is not engaged with the rack 63, the drive rack 63 is reset from the end position to the initial position.

[0040] In some embodiments, such as Figures 1-2 As shown, the anti-unevenness component 5 further includes: a movable rod 51 connected to the drive component 6; the swing plate 53 includes a linkage part 531 disposed above the pool body 1 and a stirring part 532 extending vertically downward into the pool body 1; the movable rod 51 is disposed on one side of the swing plate 53 at relative intervals; the movable rod 51 can reciprocate under the drive of the drive component 6, move towards the linkage part 531 and push the swing plate 53 from the initial position to the end position, or away from the swing plate 53; two support members 52 are disposed opposite to each other on the top of the pool body 1 in a direction perpendicular to the swing plate 53 and are slidably connected to both ends of the linkage part 531; the support members 52 are slidably connected to the swing plate 53 during the stirring process and provide support for the swing plate 53; and a second reset member, which can drive the swing plate 53 to reset from the end position to the initial position when the movable rod 51 is driven away from the swing plate 53. Specifically, the movable rod 51 reciprocates under the drive of the drive assembly 6. When the movable rod 51 approaches the swing plate 53, the swing plate 53 moves from its initial position to its final position under the push of the movable rod 51. When the movable rod 51 moves away from the swing plate 53, the second reset member drives the swing plate 53 to reset from its final position to its initial position, causing the stirring part 532 to stir back and forth in the pool 1, and the gas in the pool 1 is evenly dispersed. Alternatively, the lower end of the movable rod 51 can be connected to the swing plate 53, eliminating the need for the second reset member. The movable rod 51 drives the swing plate 53 to move synchronously, stirring in the pool 1.

[0041] In some embodiments, such as Figures 1-2 As shown, the ends of the two opposing support members 52 furthest from the movable rod 51 are connected to a fixed plate 57 parallel to the swing plate 53. The second reset member is a second reset spring 55, which is connected between the fixed plate 57 and the swing plate 53 in a direction perpendicular to the swing plate 53. When the swing plate 53 is pushed from the initial position to the end position by the movable rod 51, the swing plate 53 moves closer to the fixed plate 57, and the second reset spring 55 is compressed. When the movable rod 51 moves away from the swing plate 53, the elastic force of the second reset spring 55 causes the swing plate 53 to return from the end position to the initial position, repeating the cycle. Alternatively, the second reset member can be a cylinder, which is fixed to the fixed plate 57. The output end of the cylinder is connected to the swing plate 53. When the movable rod 51 moves away from the swing plate 53, the cylinder drives the swing plate 53 to return from the end position to the initial position.

[0042] In some embodiments, such as Figures 1-2 As shown, a guide rod 54 is connected to the fixed plate 57. The guide rod 54 is perpendicular to the swing plate 53 and passes sequentially through the linkage part 531 and the movable rod 51 along the fixed plate 57, guiding the movement direction of the swing plate 53 and the movable rod 51. The guide rod 54 is fixedly connected to the fixed plate 57 and slidably connected to the linkage part 531 and the movable rod 51, allowing the swing plate 53 and the movable rod 51 to slide along the length of the guide rod 54. A spring guide rod is also provided inside the second return spring 55. The spring guide rod is connected between the fixed plate 57 and the linkage part 531 along the length of the second return spring 55. The spring guide rod is fixedly connected to the fixed plate 57 and slidably connected to the linkage part 531, guiding the stretching and compression directions of the second return spring 55.

[0043] In some embodiments, the support member 52 includes a support plate disposed on the top of the pool body 1. The support plate has grooves recessed inward on opposite sides. The two ends of the swing plate 53 are embedded in the grooves and can reciprocate within the grooves. Limiting plates 56 are also provided at both ends of the grooves to prevent the swing plate 53 from sliding out of the grooves. The support member 52 can also be configured in other ways, such as having a slide rail along the length of the support member 52, with grooves at both ends of the swing plate 53, and the grooves reciprocating on the slide rails.

[0044] In some embodiments, the movable rod 51 includes a rod body 511 and a pressure rod 512. The rod body 511 is parallel to the swing plate 53, and the pressure rod 512 is connected to the side of the rod body 511 facing the swing plate 53 and extends towards the swing plate 53. Both ends of the rod body 511 are connected to the drive assembly 6, and under the drive of the drive assembly 6, the pressure rod 512 moves towards the linkage part 531, causing the pressure rod 512 to push the linkage part 531 from an initial position to a final position. Specifically, as shown... Figures 1-2As shown, the two ends of the rod 511 are connected to the rack 63 via connecting rods, and move linearly back and forth synchronously with the rack 63.

[0045] In some embodiments, such as Figure 3 As shown, the anti-clogging component 4 also includes a striking head 42. One end of the striking rod 41 is connected to the drive component 6, and the other end is connected to the striking head 42. Under the drive of the drive component 6, the striking head 42 continuously strikes the air intake 21 of the fan component 2. Figure 3 As shown, the striking rod 41 is connected to the rack 63 and moves synchronously with the rack 63. The shape of the striking head 42 can be set to adapt to the air intake 21 to ensure the striking effect, such as... Figure 3 The shape shown is disc-shaped, but it can also be any other shape. A buffer pad can also be provided at the contact point between the striking head 42 and the air intake 21 to make the impact force on the air intake 21 more evenly distributed and prevent the air intake 21 from being damaged due to excessive local force.

[0046] like Figure 3 As shown, the blower assembly 2 also includes a blower main unit 22 and an outlet pipe 23. After gas is drawn in through the air inlet 21, the gas is discharged through the blower main unit 22 and the outlet pipe 23 into the pool body 1. The blower main unit 22 plays a role in stabilizing the airflow and preventing airflow instability caused by the continuous impact of the anti-clogging component 4. An aerator 3 is also provided at the bottom of the pool body 1. The aerator 3 includes an air supply pipe 31, a microporous aeration pipe 32, and a support rod 33. The air supply pipe 31 is evenly distributed at the bottom of the pool body 1 by the support rod 33 and is connected to the outlet pipe 23. The microporous aeration pipe 32 is connected to the top of the air supply pipe 31 and the bottom of the air supply pipe 31. The cavity of the microporous aeration pipe 32 extends vertically upward from the bottom and gradually widens. The top of the microporous aeration pipe 32 is provided with an air outlet plate with multiple through holes. Gas enters from the bottom of the microporous aeration pipe 32, is discharged through the air outlet plate at the top of the cavity into the pool body 1, so that the gas is distributed in various positions of the pool body 1.

[0047] The working process of one embodiment of this utility model is described in detail below: The driving member 61 drives the incomplete gear 62 to rotate. When the incomplete gear 62 rotates to mesh with the rack 63, the rack 63 slides on the support plate 65, moves from the initial position to the end position, and stretches the first return spring 64. At the same time, the striking rod 41 and the movable rod 51 also move synchronously with the rack 63. The striking rod 41 drives the striking head 42 to strike the air intake 21; the movable rod 51 moves closer to the swing plate 53, so that the pressure rod 512 fits against the linkage part 531 and pushes the entire swing plate 53 toward the direction close to the fixed plate 57, and compresses the second return spring 55. During this process, the stirring part 532 stirs in the pool 1, and the swing plate 53 moves from the initial position to the end position. When the incomplete gear 62 rotates to the point where it no longer meshes with the rack 63, the rack 63, driven by the elastic force of the first return spring 64, moves from the end position to the initial position. The striking rod 41 and the movable rod 51 move synchronously with the rack 63. The striking rod 41 drives the striking head 42 away from the air inlet 21, and the movable rod 51 moves away from the swing plate 53. Driven by the second return spring 55, the swing plate 53 moves away from the fixed plate 57, moving from the end position to the initial position and stirring in the tank 1. By repeating the above steps, the anti-clogging component 4 continuously strikes the blower component 2 to prevent it from clogging, and the anti-uneven distribution component 5 continuously stirs the tank 1, making the gas distribution in the tank 1 uniform and improving the aeration efficiency of the entire aeration tank.

[0048] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
