Anti-clogging reverse dredging type bar screen cleaner

Abstract

This utility model discloses an anti-clogging reverse-scoop bar screen cleaner, which relates to the field of bar screen cleaning technology. It includes: a housing, with a bar screen fixedly connected to the inner wall of the housing, a drive motor fixedly connected to the outer wall of the housing, a sprocket assembly inside the housing, and a cleaning device at the top of the housing. This utility model intercepts impurities, floating debris, and other solid pollutants in the water through the bar screen, preventing the pollutants from spreading downstream with the water flow. Simultaneously, the sliding cooperation between the bar screen and the rake rod prevents pollutants from accumulating on the bar screen surface. A linkage rod drives the grab hook to rotate synchronously. When the rake rod carries pollutants to the top of the housing, the grab hook slides through the middle of the rake rod, scraping off fibrous, flocculent, and other easily adhered pollutants from the surface of the rake rod. This prevents long-term accumulation of pollutants from causing the rake rod to malfunction, ensuring that the rake rod is always in a pollutant-collecting state without the need for frequent manual cleaning.

Description

Technical Field

[0001] This utility model relates to the field of bar screen cleaning technology, specifically to an anti-clogging reverse-fishing bar screen cleaning machine. Background Technology

[0002] In the fields of municipal sewage treatment, industrial wastewater purification, and water conveyance in water conservancy projects, bar screens are the core equipment in the water pretreatment process. Their main function is to intercept and remove solid pollutants in the water, prevent them from clogging subsequent pipes, pumps, or treatment equipment, and ensure the stable operation of the entire water treatment system.

[0003] In existing technologies, the rake bar of traditional sludge removal machines only has the single function of scooping up dirt and lacks a structure for cleaning sticky dirt. When there are fibrous, flocculent or other easily sticky dirt in the water, these dirt may adhere to the surface and crevices of the rake bar and are difficult to remove with regular scooping actions. After long-term accumulation, the scooping space of the rake bar is occupied, which leads to a gradual decline in the dirt scooping function. Eventually, the machine needs to be stopped for manual cleaning, which is time-consuming, labor-intensive, and affects the continuous operation capability of the sludge removal machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: an anti-clogging reverse-feeding bar screen cleaner, comprising: a housing, wherein a bar screen is fixedly connected to the inner wall of the housing, a drive motor is fixedly connected to the outer wall of the housing, a sprocket assembly is provided inside the housing, and a cleaning device is provided at the top of the housing; the cleaning device includes a linkage rod, a hook is fixedly connected to the outer wall of the linkage rod, and a striking assembly is fixedly connected to the outer wall of the linkage rod, the striking assembly being linearly arrayed along the central axis of the linkage rod.

[0005] Preferably, a drive rod is rotatably connected to the inner wall of the housing, and the outer wall of the drive rod is fixedly connected to the output end of the drive motor. The drive rod meshes with a sprocket assembly via gears. The drive motor drives the drive rod to rotate synchronously, and the drive rod, through gear meshing, drives the sprocket assembly inside the housing to rotate.

[0006] Preferably, a movable rod is fixedly installed on the outer wall of the sprocket assembly, and a rake rod is fixedly connected to the outer wall of the movable rod. The outer wall of the rake rod is slidably connected to the inner wall of the grid. As the sprocket assembly rotates, the movable rod fixed to its outer wall will move synchronously and cyclically with the sprocket assembly. Since the rake rod fixed to the outer wall of the movable rod is slidably connected to the inner wall of the grid, the movable rod drives the rake rod to circulate along the surface of the grid, and the rake rod will scoop up the dirt intercepted on the grid from the bottom of the grid.

[0007] Preferably, the outer wall of the linkage rod is rotatably connected to the inner wall of the housing, and the linkage rod is connected to the drive rod via a pulley assembly.

[0008] Preferably, the striking assembly includes a handle, a rotating rod fixedly connected to the inner wall of the handle, a fixing block symmetrically rotatably connected to the outer wall of the rotating rod, a torsion spring symmetrically fixedly connected to the outer wall of the handle, and a rubber block fixedly connected to the outer wall of the handle. A hook fixed to the outer wall of the linkage rod rotates synchronously with the linkage rod. When the rake rod carrying dirt moves to the top of the box, the rotating hook slides through the middle of the rake rod, scraping off the dirt adhering to the rake rod.

[0009] Preferably, the outer wall of the fixed block is fixedly connected to the outer wall of the linkage rod, the end of the torsion spring away from the handle is fixedly connected to the outer wall of the fixed block, and the outer wall of the rubber block is slidably connected to the outer wall of the moving rod. As the fixed block rotates, the handle unfolds under centrifugal force until the rubber block fixedly connected to its surface contacts the moving rod. The rubber block on the outer wall of the handle then contacts the surface of the moving rod, causing the rubber block to strike the moving rod. The vibration generated by this striking action is transmitted to the moving rod and the rake rod, shaking off small debris adhering to the gaps in the rake rod and the connection points of the moving rod.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a screen to intercept solid pollutants such as impurities and floating objects in the water, preventing the pollutants from spreading downstream with the water flow. At the same time, the sliding cooperation between the screen and the rake rod prevents the pollutants from accumulating on the screen surface. The linkage rod drives the grab hook to rotate synchronously. When the rake rod carries the pollutants to the top of the tank, the grab hook slides through the middle of the rake rod, which can scrape off the fibrous, flocculent and other easily attached pollutants adhering to the surface of the rake rod. This prevents the long-term accumulation of pollutants from causing the rake rod to malfunction, ensuring that the rake rod is always in a pollutant-collecting state and does not require frequent manual cleaning of the rake rod.

[0012] 2. This utility model, by setting up a striking component, unfolds under the action of centrifugal force when the linkage rod rotates. The rubber block strikes the moving rod, and the vibration is transmitted to the rake rod and the screen through the moving rod. On the one hand, it can shake off small dirt from the gaps of the rake rod and the connection of the moving rod, preventing the parts from getting stuck; on the other hand, it can prevent dirt from clogging the gaps of the screen, ensuring smooth water flow, eliminating the need to stop the machine to unclog the screen, and reducing the equipment blockage rate.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example:

[0020] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an anti-clogging reverse-feeding bar screen cleaner, comprising: a housing 1, a bar screen 3 fixedly connected to the inner wall of the housing 1, a drive motor 6 fixedly connected to the outer wall of the housing 1, a sprocket assembly 2 arranged inside the housing 1, and a cleaning device 8 arranged at the top of the housing 1; the cleaning device 8 includes a linkage rod 81, a hook 82 fixedly connected to the outer wall of the linkage rod 81, and a striking assembly 83 fixedly connected to the outer wall of the linkage rod 81, the striking assembly 83 being linearly arrayed along the central axis of the linkage rod 81.

[0021] The inner wall of the housing 1 is rotatably connected to a drive rod 7, and the outer wall of the drive rod 7 is fixedly connected to the output end of the drive motor 6. The drive rod 7 meshes with the sprocket set 2 through gears.

[0022] A movable rod 4 is fixedly installed on the outer wall of the sprocket assembly 2. A rake rod 5 is fixedly connected to the outer wall of the movable rod 4. The outer wall of the rake rod 5 is slidably connected to the inner wall of the grid 3.

[0023] The outer wall of the linkage rod 81 is rotatably connected to the inner wall of the housing 1, and the linkage rod 81 is connected to the drive rod 7 through the pulley set 9.

[0024] The striking assembly 83 includes a handle 831, a rotating rod 834 fixedly connected to the inner wall of the handle 831, a fixing block 832 symmetrically rotatably connected to the outer wall of the rotating rod 834, a torsion spring 833 symmetrically fixedly connected to the outer wall of the handle 831, and a rubber block 835 fixedly connected to the outer wall of the handle 831.

[0025] The outer wall of the fixed block 832 is fixedly connected to the outer wall of the linkage rod 81, the end of the torsion spring 833 away from the handle 831 is fixedly connected to the outer wall of the fixed block 832, and the outer wall of the rubber block 835 is slidably connected to the outer wall of the moving rod 4.

[0026] Working principle:

[0027] When in use, start the drive motor 6 fixed on the outer wall of the box 1. Its output end is directly fixed to the drive rod 7 rotatably connected to the inner wall of the box 1. The drive motor 6 drives the drive rod 7 to rotate synchronously. The drive rod 7 drives the sprocket group 2 inside the box 1 to rotate through gear meshing, and drives the linkage rod 81 to rotate synchronously through the pulley group 9, providing power to the cleaning device 9.

[0028] The grid 3 fixed to the inner wall of the tank 1 serves as the first line of defense. When water containing contaminants flows through the tank 1, the gaps in the grid 3 will intercept impurities and floating objects in the water, preventing contaminants from flowing downstream with the water. As the sprocket assembly 2 rotates, the movable rod 4 fixed to its outer wall will move synchronously and cyclically with the sprocket assembly 2. Since the rake rod 5 fixed to the outer wall of the movable rod 4 is slidably connected to the inner wall of the grid 3, the movable rod 4 drives the rake rod 5 to move cyclically along the surface of the grid 3. The rake rod 5 will scoop up the contaminants intercepted on the grid 3 from the bottom of the grid 3 and transport the contaminants to the top of the tank 1, completing the separation of contaminants from the water.

[0029] The hook 82 fixed on the outer wall of the linkage rod 81 rotates synchronously with the linkage rod 81. When the rake rod 5 carries dirt to the top of the box 1, the rotating hook 82 will slide through the middle of the rake rod 5 to scrape off the dirt stuck on the rake rod 5, preventing the dirt from adhering for a long time and causing the rake rod 5 to malfunction. When the linkage rod 81 rotates, it drives the fixed block 832 to rotate synchronously. When the handle 834 rotates with the fixed block 832, the handle 831 rotates and unfolds under the action of centrifugal force until the rubber block 835 fixedly connected to its surface contacts the moving rod 4. The rubber block 835 on the outer wall of the handle 831 will contact the surface of the moving rod 4, causing the rubber block 835 to strike the moving rod 4. The vibration generated by this strike will be transmitted to the moving rod 4 and the rake rod 5, shaking off the small dirt attached to the gaps of the rake rod 5 and the connection of the moving rod 4, while preventing the dirt from clogging the gaps of the grid 3. When the linkage rod 81 stops rotating, the handle 831 will rotate and reset through the torsion spring 833.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
