Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and more specifically, to a device for collecting scum from wastewater treatment ponds. Background Technology

[0002] In the field of modern wastewater treatment, the collection and treatment of scum has always been an important and complex issue. Traditional wastewater treatment methods typically rely on gravity separation and mechanical scraping, but these methods have some shortcomings in terms of treatment efficiency and reliability.

[0003] Currently, there are some scum suction devices on the market, but these devices mostly rely on a single suction principle and cannot effectively adapt to changes in the scum layer. When water levels fluctuate or scum thickness is uneven, the suction capacity of these devices is greatly limited, making it difficult to achieve continuous and stable scum collection. In some small-scale wastewater treatment systems, manual periodic scum removal is still necessary. This is not only time-consuming and labor-intensive but also inefficient, failing to meet the requirements of automation and continuity in modern wastewater treatment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a scum collection device for sewage treatment ponds, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: a scum collection device for sewage treatment ponds, comprising a water storage tank, a fixed cylinder fixedly connected inside the water storage tank, a guide ring fixedly connected to the upper end of the fixed cylinder, an outer barrel inside the fixed cylinder, an inner barrel inside the outer barrel, and a collection device inside the fixed cylinder;

[0005] The collecting device includes a fixed plate, which is fixedly connected to the inside of a fixed cylinder. A rotating shaft is rotatably connected to the front of the fixed plate. A swing plate is fixedly sleeved on the outer wall of the rotating shaft. A movable groove is formed inside the swing plate. A motor is fixedly connected to the back of the fixed plate. A turntable is fixedly connected to the output end of the motor. A sliding shaft is fixedly connected to the front of the turntable. A connecting shaft is slidably connected inside the movable groove. A moving rod is fixedly connected to one end of the connecting shaft. The top of the moving rod is fixedly connected to the bottom of the outer cylinder.

[0006] Preferably, the sliding shaft is slidably connected inside the movable groove.

[0007] Preferably, a limiting frame is fixedly connected to the front of the fixed plate, and the moving rod is slidably connected inside the limiting frame.

[0008] Preferably, a fixing component is provided on the inner side of the outer tub. The fixing component includes a mounting hole, which is opened on the inner side of the outer tub. A spring is fixedly connected to the inner wall of the mounting hole. A moving block is fixedly connected to the other end of the spring. A positioning rod is fixedly connected to the other side of the moving block. Positioning holes are opened on both sides of the inner tub. A moving groove is opened at the upper end of the outer tub. A push rod is fixedly connected to the upper end of the positioning rod.

[0009] Preferably, the push rod is slidably connected inside the moving groove, and the moving block is slidably connected inside the mounting hole.

[0010] Preferably, a handle is fixedly connected to the upper end of the inner tub.

[0011] The advantages of this application are:

[0012] (1) The collection device is driven by a motor to rotate the turntable, which causes the sliding shaft to slide in the movable groove, thereby causing the swing plate to swing up and down. This swing mechanism enhances the ability to suck up scum on the water surface, ensuring that the scum can be effectively sucked into the inner tank.

[0013] (2) The setting of the fixing components and the application of springs enable the moving block to automatically return to its original position when no external force is applied. This design not only makes the inner barrel easy to remove, but also ensures accurate positioning when it is put back, reducing the difficulty of operation. The process of releasing or fixing the inner barrel by a simple pushing operation is greatly simplified and the user's work efficiency is improved. Attached Figure Description

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] See Figures 1-4 This embodiment provides a scum collection device for a sewage treatment pond, including a storage tank 1 for storing sewage to be treated. Its internal structure provides an effective working environment. A fixed cylinder 2 is fixedly connected inside the storage tank 1, serving as the central component of the entire device and ensuring the stability of other components. A guide ring 3 is fixedly connected to the upper end of the fixed cylinder 2. An outer barrel 4 is provided inside the fixed cylinder 2, and an inner barrel 5 is provided inside the outer barrel 4. A collection device is provided inside the fixed cylinder 2. The collection device includes a fixed plate 61, which is fixedly connected inside the fixed cylinder 2. A rotating shaft 62 is rotatably connected to the front of the fixed plate 61. A swing plate 63 is fixedly sleeved on the outer wall of the rotating shaft 62. A movable groove 64 is opened inside the swing plate 63. A motor 65 is fixedly connected to the back of the fixed plate 61. A turntable 66 is fixedly connected to the output end of the motor 65. A sliding shaft 67 is fixedly connected to the front of the turntable 66. A connecting shaft 68 is slidably connected inside the movable groove 64. A moving rod 610 is fixedly connected to one end of the connecting shaft 68. The top of the moving rod 610 is fixedly connected to the bottom of the outer barrel 4. The sliding shaft 67 is slidably connected inside the movable groove 64. The front of the fixed plate 61 is fixedly connected to the limit frame 69, and the moving rod 610 is slidably connected inside the limit frame 69.

[0025] In practical use, the water level inside the storage tank 1 is higher than that inside the fixed cylinder 2. When using the collection device, the motor 65 is started to drive the turntable 66 to rotate. When the turntable 66 rotates, it drives the sliding shaft 67 to rotate as well. As the sliding shaft 67 rotates, it slides inside the movable groove 64. Since the sliding shaft 67 moves back and forth between the upper and lower ends, it drives the swing plate 63 to swing within the range of vertical movement via the rotating shaft 62 through the movable groove 64. Then, the moving rod 610 can be driven to move up and down inside the limiting frame 69 through the connecting shaft 68, which is also slidably connected inside the movable groove 64. This causes the upper outer cylinder 4 and inner cylinder 5 to move up and down. When it moves downward, a pressure difference is generated, which causes the scum floating on the water surface to be sucked into the inner cylinder 5, while the water is discharged from the cylinder.

[0026] Example 2

[0027] See Figures 1-4 Based on Embodiment 1, a fixing component is provided on the inner side of the outer tub 4. The fixing component includes a mounting hole 71, which is located on the inner side of the outer tub 4. A spring 72 is fixedly connected to the inner wall of the mounting hole 71 to ensure that the moving block 73 automatically returns to its original position when no external force is applied. The other end of the spring 72 is fixedly connected to the moving block 73, and the other side of the moving block 73 is fixedly connected to a positioning rod 74. Positioning holes 77 are provided on both sides of the inner tub 5, and a moving groove 75 is provided at the upper end of the outer tub 4. A push rod 76 is fixedly connected to the upper end of the positioning rod 74. The push rod 76 is slidably connected inside the moving groove 75, and the moving block 73 is slidably connected inside the mounting hole 71. A handle 78 is fixedly connected to the upper end of the inner tub 5 for easy removal of the inner tub 5.

[0028] When the above-mentioned equipment is used to treat the scum in the inner barrel 5, the push rod 76 is first pushed to both sides to slide outward inside the moving groove 75. This will cause the positioning rod 74 and the moving block 73 to move inside the mounting hole 71. When the positioning rod 74 leaves the positioning hole 77 on the side of the inner barrel 5, the inner barrel 5 can be taken out by the handle 78. After cleaning, repeat the above operation before taking out the inner barrel 5, and put the inner barrel 5 back in. At this time, release the push rod 76. Then, under the action of the spring 72, the moving block 73 will be pushed to push the positioning rod 74 into the positioning hole 77.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
