Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a screen cleaning device. Background Technology

[0002] In the process of domestic sewage treatment, the bar screen is a pretreatment unit. The main function of the bar screen is to intercept large particulate pollutants in the sewage, such as twigs, stones, feathers, and bits of meat. If these debris are not removed in time, they will gradually accumulate and clog the bar screen, obstructing water flow and potentially causing equipment damage or shutdown of the sewage treatment facility. For example, blockage by foreign objects can increase the liquid level difference before and after the bar screen, increasing the flow velocity through the screen and thus reducing the removal efficiency of the bar screen.

[0003] In existing technologies, bar screen cleaners are devices used to remove large solid objects from wastewater within bar screen tanks. Their main function is to intercept larger particles such as branches and stones in wastewater through metal bar screens, thereby protecting subsequent treatment equipment from damage and reducing the environmental impact of pollutants. However, when using a bar screen cleaner, if the influent contains a large amount of debris (such as fibers, plastic bags, hair, etc.), this debris can easily become entangled or stuck on the bar screen bars or rake teeth, causing blockages and affecting the subsequent treatment effect of the bar screen cleaner. Therefore, we propose a bar screen tank cleaning device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a bar screen cleaning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, a bar screen cleaning device is disclosed, including a bar screen cleaning machine body 1. Two protective plates 2 are hinged to the outer wall of the bar screen cleaning machine body 1. The outer walls of the two protective plates 2 are provided with mounting holes 3. The protective plates 2 are fixed to the inner wall of the bar screen by existing screws passing through the mounting holes 3, which serves to guide the sewage flow. An inclined frame 4 is fixedly connected to the outer wall of the bar screen cleaning machine body 1. The interior of the inclined frame 4 is inclined to facilitate the discharge of debris. A frame is fixedly connected to the outer wall of the inclined frame 4. A motor 5 is fixedly connected to the top of the frame. A round hole is provided on the outer wall of the inclined frame 4. The inner wall of the round hole is rotatably connected to the outer wall of the output shaft of the motor 5.

[0023] A rotating roller 6 is fixedly connected to one end of the output shaft of the motor 5. A bearing is fixedly sleeved on the outer wall of the rotating roller 6. The outer ring of the bearing is fixedly connected to the inner wall of the inclined frame 4. Multiple brushes 7 are evenly fixedly connected to the outer wall of the rotating roller 6. The operation of the motor 5 drives the rotating roller 6 and the multiple brushes 7 to rotate.

[0024] An electric push rod 16 is fixedly connected to the outer wall of the bar screen cleaner body 1. A sliding hole is opened on the outer wall of the bar screen cleaner body 1. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod 16. A water inlet tank 8 is fixedly connected to the outer wall of the output end of the electric push rod 16. The operation of the electric push rod 16 drives the water inlet tank 8 to move back and forth, so that the high-pressure nozzle 12 can evenly wash the metal bar screen or rake teeth. Two hollow ear plates 9 are fixedly connected to each other on the outer wall of the water inlet tank 8. Four supports 14 are fixedly connected to the outer wall of the bar screen cleaner body 1. The bottom of each of the four supports 14 is fixedly connected to a foot plate 15.

[0025] The outer wall of the water inlet tank 8 is provided with a water inlet assembly, which includes two water inlet pipes 10. The outer wall of the bar screen cleaner body 1 has two through holes. The inner walls of the two through holes are slidably connected to the outer walls of the water inlet pipes 10 respectively. The two through holes assist the two water inlet pipes 10 in moving.

[0026] One end of each of the two water inlet pipes 10 is fixedly connected to the outer wall of the two ear plates 9. The inner walls of the two water inlet pipes 10 are slidably connected to the same U-shaped pipe 11. The contact surface between the U-shaped pipe 11 and the water inlet pipe 10 is designed with a sealing ring to ensure the sealing between the two. The U-shaped pipe 11 is fixedly supported by the existing pipe bracket to prevent it from moving when the water inlet pipe 10 moves. Multiple high-pressure nozzles 12 are fixedly connected to the bottom of the water inlet tank 8. A fixed pipe 13 is fixedly connected to the outer wall of the U-shaped pipe 11. A water pump is fixedly connected to one end of the fixed pipe 13. The water inlet pipes 10, U-shaped pipes 11 and fixed pipes 13 are all made of stainless steel.

[0027] Working principle: During use, the bottom of the bar screen cleaner body 1 is placed in the bar screen tank. After the sewage passes through the metal bar and rake teeth on the bar screen cleaner body 1, the debris in the sewage is carried upwards. At the end of the movement, the debris falls downwards due to its own weight and is transported out by the existing belt conveyor. The debris adhering to or wrapped around the metal bar and rake teeth is driven by the motor 5 to rotate the rotating roller 6 counterclockwise. The rotation of the rotating roller 6 drives multiple brushes 7 to rotate, which clean the outer wall of the metal bar and rake teeth and scrape it downwards. At the same time, the water pump operates to pump external water into the fixed pipe 13, and the water flows... The water enters the U-shaped pipe 11 through the fixed pipe 13, and finally flows into the two inlet pipes 10. It then enters the two ear plates 9 through the two inlet pipes 10 and finally flows into the water tank 8. The water is sprayed out by multiple high-pressure nozzles 12 below to wash the metal grid and rake teeth. The electric push rod 16 drives the water tank 8 to move back and forth. The back and forth movement of the water tank 8 drives the two ear plates 9 and the two inlet pipes 10 to move back and forth. When the two inlet pipes 10 move back and forth, the two ends of the U-shaped pipe 11 are located inside the two inlet pipes 10. When the water sprayed by the high-pressure nozzles 12 impacts downwards, it is combined with the rotation of the brush 7 to improve the cleaning effect on the metal grid and rake teeth.
