[0035] Embodiment 1

[0036] Please refer to Figures 1-5 A grid structure convenient to clean for a desulfurization wastewater sedimentation tank, comprising: a frame 1, a plurality of grid fences 2 are rotatably connected to one side of the inner wall of the frame 1, a protective shell 3 is fixedly connected to one side of the grid fence 2, a synchronous driving mechanism 4 is arranged in the protective shell 3, the driving mechanism 4 drives one of the grid fences 2 through a driving motor, the plurality of grid fences 2 are connected through a belt and a belt pulley, when the driving motor drives one of the grid fences 2, the synchronous rotation of the plurality of grid fences 2 is realized through the transmission between the belt pulleys, a spray box 5 is rotatably connected to the upper side of the inner wall of the frame 1, a plurality of high-pressure nozzles 6 are arranged on the lower side of the spray box 5, a corrugated pipe 7 is arranged on the upper side of the spray box 5, and an adjusting mechanism 8 is arranged on the upper side of the inner wall of the frame 1. One end of the plurality of grid fences 2 extends to one side of the frame 1, and the upper end of the corrugated pipe 7 extends to the upper side of the frame 1. The inner wall of the frame 1 is provided with a plurality of scraper plates 9 matched with the grid fences 2. Both ends of the scraper plate 9 are fixedly connected with a fixed block 10, and the fixed block 10 is fixedly connected with the inner wall of the frame 1 through bolts. A plurality of mounting holes 11 are formed in the two sides of the frame 1.

[0037] The implementation process: the multiple mounting holes 11 opened on both sides of the frame 1 provide convenience for the installation of the entire grid structure in the desulfurization wastewater sedimentation tank. Through cooperation with the connecting parts at the corresponding positions of the sedimentation tank wall, the frame 1 can be firmly fixed at the water inlet of the sedimentation tank by using bolts and other connecting parts, ensuring that the wastewater can flow evenly through the grid fence 2 and guaranteeing the stability of the equipment installation, preventing wastewater bypassing, effectively playing a pre-filtering role. The synchronous driving mechanism 4 (the synchronous driving mechanism 4 drives one of the grid fences 2 through a driving motor, and the multiple grid fences 2 are connected by belts and belt pulleys. When the driving motor drives one of the grid fences 2, the synchronous rotation of the multiple grid fences 2 is achieved through the transmission between the belt pulleys) drives the grid fence 2, causing the grid fence 2 to slowly rotate around the rotating connection with the frame 1. When the grid fence 2 filters the desulfurization wastewater, it will intercept a large amount of debris. The rotating process changes the attachment state of the debris to the grid fence 2, making it easier to clean. At the same time, the scraper 9 arranged on the inner wall of the frame 1 plays a key role. The scraper 9 is firmly fixed on the inner wall of the frame 1 by bolts through the two end fixed blocks 10, and tightly cooperates with the rotating grid fence 2. When the grid fence 2 rotates, the scraper 9 scrapes off the debris attached to the surface of the grid fence 2 by virtue of its rigidity. The debris falls into the bottom of the sedimentation tank under the action of gravity, completing the preliminary cleaning.

[0038] The implementation benefits: the rotating cleaning of the grid fence 2 and the washing of the high-pressure spray head 6 greatly improve the cleaning efficiency compared to the traditional grid relying on manual cleaning or single simple mechanical cleaning method.

[0039] Example 2

[0040] The adjusting mechanism 8 includes a mounting groove 81 opened on the lower side of the inner wall of the frame 1. A gas cylinder 82 is arranged on one side of the inner wall of the mounting groove 81. An installation block 83 is fixedly connected to the output end of the gas cylinder 82. A connecting rod 84 is arranged between the installation block 83 and the spray box 5.

[0041] Implementation process: when the grid fence 2 is blocked by stubborn debris and cannot be completely removed by simple rotating cleaning, the adjusting mechanism 8 starts to work. The gas cylinder 82 receives a signal and starts. Its output end pushes the installation block 83 to slide on the inner wall of the mounting groove 81. Since the installation block 83 is rotationally connected to the spray box 5 through the connecting rod 84, as the installation block 83 moves, the connecting rod 84 drives the spray box 5 to rotate on the upper side of the inner wall of the frame 1, adjusting the angle of the spray box 5. The external washing water source is connected to the spray box 5 through the corrugated pipe 7. The multiple high-pressure spray heads 6 arranged on the lower side of the spray box 5 spray high-pressure water flow, impacting the grid fence 2 from all directions and forcefully removing the tightly attached debris, further ensuring the filtering performance of the grid fence 2.

[0042] Implementation benefits: when the need for flushing, the adjustment mechanism 8 can be adjusted according to the preset program or field sensor feedback signal, automatic adjustment spray box 5 angle for high pressure flushing, greatly reduce the labor intensity of the operator, improve the automation level of the whole desulfurization wastewater treatment process.

[0043] The above embodiments are only used to illustrate the technical solutions described in the utility model and not to limit the utility model. Although the utility model has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific embodiments, and therefore any modification or equivalent replacement of the utility model, and all technical solutions and improvements without departing from the spirit and scope of the invention are all included in the scope of the claims of the utility model.
