Description

Technical Field

[0001] The utility model relates to the technical field of grille cleaning, in particular to an automatic grille cleaning device. Background Art

[0002] The grating plate, also known as the steel grating, is a steel product made of flat steel that is cross-arranged at a certain interval and cross bars and welded into a grid in the middle. In the process of treating sludge (solid, semi-solid and liquid waste produced after sewage treatment), the sludge treatment plant will install a grating at the inlet of the sludge treatment facility, mainly using physical treatment methods to intercept larger floating or suspended matter.

A slide groove 73 adapted to the slide rail 21 is provided at the bottom of the movable seat 7, and a slider 72 for cooperating with the side wall of the slide rail 21 is provided on the inner wall of the slide groove 73.

[0059] By setting up a sliding assembly, when the grille needs to be cleaned after being used for a long time, the movable seat 7 on the sliding assembly is first slid to the outside of the protective shell 1, and then the grille is placed on the movable seat 7 in the sliding assembly, and then the grille is fixed by the limiting assembly, and then the movable seat 7 is pushed to drive the grille into the inner cavity of the cleaning chamber 4, and the brush roller 3 drives the brush 31 to brush one side of the grille, while multiple water spray seats 6 can simultaneously flush the other side of the grille, so that the grille is fully cleaned, replacing the traditional manual cleaning. At the same time, due to the heavy weight of the grille itself, it is difficult to turn it over during manual cleaning, resulting in low efficiency and incomplete cleaning during the grille cleaning process.

[0060] Furthermore, the materials of the movable seat 7 and the slide rail 21 are both polytetrafluoroethylene. When the movable seat 7 slides on the slide rail 21, the wear-resistant material of the polytetrafluoroethylene can ensure stable sliding operation.

[0061] The length between the outer ends of each group of two movable seats 7 is adapted to the length of the grid.

[0062] By setting the slide groove 73, when installing the sliding component, the moving seat 7 is first slid and installed through one end of the slide rail 21, and then the slide rail 21 and the fixed plate 22 are fixed. In combination with the I-shaped setting of the slide rail 21, the slider 72 of the moving seat 7 is inserted into the grooves on both sides of the slide rail 21, which is more stable when moving.

[0063] First, place the grille on the movable seat 7, and the bracket 74 supports the grille. After the grille is fixed with the limit assembly, the grille is then pushed so that the grille slides on the slide rail 21 through the bracket 74 and moves to the inner cavity of the cleaning chamber 4. Then, when the movable seat 7 drives the grille to the specified position, the drive motor 51 is started to drive the lower transmission shaft 52, so that the lower transmission shaft 52 drives the upper transmission shaft 54 ​​to rotate synchronously through the pulley assembly 53. Then, the upper transmission shaft 54 ​​drives the brush roller 3 to rotate, so that the brush roller 3 drives the brush 31 to brush the surface of the grille, and the high-pressure nozzles 61 on the multiple water spray seats 6 continuously flush the grille with high-pressure water flow to clean the mud and dirt on the surface of the grille.

[0064] Furthermore, the limit assembly includes a limit seat 71 and a pressing assembly.

The end of the rotating rod 76 located outside the limit seat 71 is fixedly mounted with a rotating disk 77. The surface of the rotating rod 76 located in the inner cavity of the limit seat 71 is provided with a thread. The surface of the rotating rod 76 is threadedly connected to the limit plate 75. One end of the limit plate 75 extends to the outside of the limit seat 71. The surface of the limit seat 71 is provided with a movable groove for vertical movement of the limit plate 75.

[0065] When the limiting assembly is working, when the grille is slid inward from one side of the moving seat 7 and placed on the moving seat 7, the bracket 74 then supports the grille, and the surface of the bracket 74 matches the surface of the grille. Then, the rotating disk 77 is rotated to rotate the rotating rod 76, and then the rotating rod 76 drives the limiting plate 75 to move downward through the thread, so that the lower surface of one end of the limiting plate 75 located outside the limiting seat 71 fits the surface of the grille for fixation.

[0066] Furthermore, the sliding assembly also includes a threaded rod 23 and a servo motor 24. The two ends of the threaded rod 23 are rotatably connected to the fixed plate 22 and the support plate 2 respectively. The servo motor 24 is fixedly mounted on the support plate 2 and is transmission-connected to the threaded rod 23 through a coupling. The interior of the movable seat 7 is fixedly provided with an internal threaded sleeve that passes through the front and rear end surfaces. The movable seat 7 is mounted on the threaded rod 23 through the internal threaded sleeve and is threadedly connected to the threaded rod 23.

[0067] By setting up the servo motor 24, when the grille is placed on the moving seat 7, the servo motor 24 is started, so that the servo motor 24 drives the threaded rod 23 to rotate, so that the threaded rod 23 can be threadedly matched with the internal threaded sleeve inside the moving seat 7, thereby driving the moving seat 7 on the threaded rod 23 to move inward. At this time, the other two moving seats 7 will also move inward due to the force of the grille moving inward, thereby replacing the manual pushing of the grille to move, with a simple structure and saving time and effort.
