Description

Technical Field

[0001] This utility model relates to the field of defoaming and impurity removal equipment for aeration tanks, specifically to a defoaming and impurity removal device for aeration tanks. Background Technology

[0002] The defoaming and impurity removal device for aeration tanks is a specialized device used in wastewater treatment systems to control foam and remove impurities. Its core function is to maintain the stable operation of the aeration tank and prevent foam overflow and impurity accumulation from affecting treatment efficiency.

[0003] Currently available defoaming and impurity removal devices for aeration tanks can achieve basic foam elimination, but they cannot adjust the working position of the defoaming device in real time according to changes in the liquid level in the aeration tank. They lack the ability to adaptively adjust the water level, which greatly reduces the defoaming effect when the liquid level fluctuates. Secondly, after the defoaming device disperses the foam on the water surface, it lacks an effective mechanism for timely collection of floating matter such as grease and scum, which makes these pollutants easy to accumulate again or spread with the water flow, affecting the overall treatment effect.

The lifting frame is mounted on the movable frame and the lifting frame is slidably connected to the movable frame; Defoaming rollers, the number of which is several, are set on the lifting frame; The power unit is mounted on the lifting frame and is connected to several defoaming rollers. The power unit drives the several defoaming rollers to rotate to eliminate foam in the aeration tank body. The lifting assembly is mounted on the movable frame. The output end of the lifting assembly is connected to the lifting frame. The lifting assembly is used to drive the lifting frame to move vertically along the aeration tank body to adapt to the liquid level inside the aeration tank body. The impurity removal component is mounted on a movable frame. A filter screen is connected to the output end of the impurity removal component. The impurity removal component drives the filter screen to contact the liquid surface of the aeration tank body to collect grease and scum on the liquid surface of the aeration tank body in real time.

[0006] Preferably, the drive assembly includes two mounting plates, which are respectively fixedly mounted on the lower surfaces of two mounting brackets. A first motor is fixedly mounted on one of the mounting plates, and a screw is fixedly mounted on the output end of the first motor. The screw passes through one of the mounting plates and is rotatably connected to the other mounting plate. A moving block is threadedly connected to the screw.

[0007] Preferably, grooves are provided on the two inner sidewalls of the aeration tank body, and sliders that are adapted to the grooves are fixedly installed on the two outer sidewalls of the moving frame, with the two sliders slidably connected to the two grooves.

[0009] Preferably, the power assembly includes a second motor, which is fixedly mounted on the top surface of the lifting frame. One end of each of the several defoaming rollers is fixedly mounted with a connecting shaft. The several connecting shafts pass through the top surface of the lifting frame and are rotatably connected to the top surface of the lifting frame. Sprockets are fixedly mounted on the outer side of each of the several connecting shafts located on the top surface of the lifting frame. The several sprockets are connected to each other by chain drive. The output end of the second motor is fixedly connected to one of the connecting shafts.

By setting a driving component on the aeration tank to move a moving block along the length of the tank, it achieves comprehensive coverage of the aeration tank area. The lifting component drives the lifting frame to move up and down vertically, allowing the defoaming roller to adapt to different liquid levels in the aeration tank. This solves the problem that traditional devices cannot adjust their height according to water level changes, ensuring that the defoaming component is always in the optimal working position. The impurity removal component can adjust one of the impurity removal filters to contact the liquid surface of the aeration tank according to the direction of the moving frame. This ensures that no matter which direction the moving frame moves, there will always be an impurity removal filter following behind the moving frame, promptly collecting the grease and scum floating on the liquid surface after the foam is dispersed. This achieves simultaneous operation of foam elimination and impurity removal, ultimately realizing an integrated treatment effect of adaptive water level changes, defoaming, and impurity removal, improving the operational stability and treatment efficiency of the aeration tank.

[0018] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0019] Example 1: like Figures 1 to 3 As shown, this utility model provides a defoaming and impurity removal device for an aeration tank, including an aeration tank body 1, and further comprising: Mounting bracket 2, there are two mounting brackets 2, and the two mounting brackets 2 are set on the aeration tank body 1; A drive assembly is mounted on the mounting frame 2 and a movable block 3 is connected to the drive assembly. The drive assembly is used to drive the movable block 3 to move along the length of the aeration tank. The movable frame 4 is mounted on the movable block 3 and is slidably connected to the aeration tank body 1. Lifting frame 5 is mounted on the movable frame 4 and is slidably connected to the movable frame 4; Defoaming roller 6, the number of defoaming rollers is several, and several defoaming rollers 6 are set on the lifting frame 5; The power component is mounted on the lifting frame 5 and is connected to several defoaming rollers 6. The power component drives the several defoaming rollers 6 to rotate to eliminate foam in the aeration tank body 1. The lifting assembly is mounted on the movable frame 4. The output end of the lifting assembly is connected to the lifting frame 5. The lifting assembly is used to drive the lifting frame 5 to move along the vertical direction of the aeration tank body 1 to adapt to the liquid level in the aeration tank body 1. The impurity removal component is mounted on the movable frame 4. The output end of the impurity removal component is connected to the impurity removal filter screen 7. The impurity removal component drives the impurity removal filter screen 7 to contact the liquid surface of the aeration tank body 1 so as to collect the grease and scum on the liquid surface of the aeration tank body 1 in real time.

[0020] When in use, start the equipment. The drive component will move the mobile frame 4 along the length of the aeration tank. The lifting component will adjust the lifting frame 5 to the appropriate position of the aerator liquid surface to ensure that the defoaming roller 6 just contacts the liquid surface. At the same time, the power component will start, driving multiple defoaming rollers 6 to rotate at high speed to break up the foam on the water surface. During the movement, the impurity removal component will work in sync, driving the impurity removal filter 7 to move along the water surface to collect the broken foam, grease and other scum. When the equipment moves to the other end of the aeration tank, it will move from there to the starting point to carry out a new round of defoaming and impurity removal operations.

[0021] Example 2: like Figures 1 to 3As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, the drive assembly includes two mounting plates 9, which are respectively fixedly mounted on the lower surfaces of two mounting brackets 2. A first motor 8 is fixedly mounted on one of the mounting plates 9, and a screw 10 is fixedly mounted on the output end of the first motor 8. The screw 10 passes through one of the mounting plates 9 and is rotatably connected to the other mounting plate 9. A moving block 3 is threadedly connected to the screw 10. The motor drives the screw 10 connected between the two mounting plates 9 to rotate, and the moving block 3 is threadedly connected to the screw 10. When the screw 10 rotates, the moving block 3 moves back and forth along the screw 10. The forward and reverse rotation of the motor can control the forward and backward movement of the moving block 3, ensuring that the defoaming device works stably above the aeration tank.

[0022] Furthermore, grooves 11 are provided on the two opposite inner sidewalls of the aeration tank body 1, and sliders 12 adapted to the grooves 11 are fixedly installed on the two opposite outer sidewalls of the movable frame 4. The two sliders 12 are slidably connected to the two grooves 11. When the drive assembly moves the movable frame 4, the two sliders 12 on the movable frame 4 will slide smoothly along the grooves 11 of the tank wall. The cooperation between the sliders 12 and the grooves 11 ensures that the entire defoaming device can move back and forth smoothly, and avoids the movable frame 4 from rotating with the screw 10.

[0023] Furthermore, the two inner sidewalls of the movable frame 4 are each provided with a slide rail 13 in the vertical direction, and the two outer sidewalls of the lifting frame 5 are each fixedly installed with a slide block 14, which is slidably connected to the two slide rails 13 respectively. When the height needs to be adjusted, the lifting assembly drives the lifting frame 5 to move, and the slide block 14 will rise and fall along the slide rail 13, ensuring the smooth movement of the lifting frame 5. According to the changes in the liquid level in the aeration tank, the defoaming roller 6 on the lifting frame 5 is automatically adjusted to a suitable working height.

[0024] Furthermore, the power assembly includes a second motor 15, which is fixedly mounted on the top surface of the lifting frame 5. A connecting shaft 16 is fixedly mounted at one end of each of several defoaming rollers 6. These connecting shafts 16 pass through and are rotatably connected to the top surface of the lifting frame 5. Sprockets 17 are fixedly mounted on the outer sides of each connecting shaft 16 on the top surface of the lifting frame 5. These sprockets 17 are connected by a chain 18. The output end of the second motor 15 is fixedly connected to one of the connecting shafts 16. The second motor 15 is mounted on the upper surface of the lifting frame 5 via a mounting frame. It drives one of the defoaming rollers 6 to rotate via the connecting shafts 16. The other defoaming rollers 6 are linked by the top sprockets 17 and the chain 18. When one defoaming roller 6 rotates, the others rotate synchronously.

[0025] Furthermore, the lifting assembly includes two first electric telescopic rods 19, which are respectively fixedly installed on the bottom surface of the movable frame 4, and the telescopic ends of the two first electric telescopic rods 19 are respectively fixedly connected to the top surface of the lifting frame 5. When the height needs to be adjusted, the two telescopic rods will extend or retract synchronously, moving the entire defoaming roller 6 device smoothly up and down, ensuring a stable and balanced lifting process.

[0026] Furthermore, the impurity removal assembly includes two fixed plates 20, which are respectively fixedly installed on both sides of the movable frame 4. A second electric telescopic rod 21 is fixedly installed on the lower surface of each of the two fixed plates 20. There are two impurity removal filter screens 7, each with a mounting base 22. The telescopic ends of the two second electric telescopic rods 21 are respectively fixedly connected to the two mounting bases 22. When the defoaming roller 6 moves, the filter screen located behind the moving direction descends to contact the water surface, while the other filter screen remains raised, ensuring that only one filter screen is always behind the defoaming roller 6 to collect the broken foam residue and floating grease immediately. When the defoaming roller 6 moves back and forth, the two filter screens work alternately. When moving forward, one filter screen is responsible for collection, and when returning, the other filter screen takes over. This alternating operation ensures continuous collection and avoids mutual interference between the two filter screens.

[0027] Furthermore, the two impurity removal screens 7 are semi-circular and inclined. When the device is running, the alternately descending screens cut into the water surface at an inclined angle. This semi-circular and inclined structure can more effectively catch floating grease and debris during movement.

[0028] Furthermore, several protrusions 23 are evenly arrayed on the outer circumferential surface of the defoaming roller 6. When the motor drives the defoaming roller 6 to rotate, these densely arranged branches agitate the water surface at high speed, breaking the foam into small pieces. This even array design ensures that the foam in each area is fully processed.

[0029] The working principle of the defoaming and impurity removal device for an aeration tank described in this application is as follows: The motor drives the screw 10 to move the mobile frame 4 back and forth along the length of the aeration tank. The mobile frame 4 is equipped with a height-adjustable bracket. The height can be automatically adjusted according to the water level by an electric telescopic rod to ensure that the defoaming roller 6 is always in the optimal working position. The defoaming roller 6 is driven to rotate by the motor through the sprocket 17, which can effectively break up the foam on the water surface. At the same time, the device is also equipped with height-adjustable impurity removal filter screens 7 on both sides. The height is controlled by the electric telescopic rod. When the impurity removal filter screens 7 on both sides move with the mobile frame 4, only one of them falls down, ensuring that the fallen impurity removal filter screen 7 always follows behind the mobile frame 4 in the direction of movement. While the defoaming roller 6 on the mobile frame 4 breaks up the foam, it also collects the grease and scum on the water surface in time.

[0030] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
