Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1: Please refer to Figure 1 - Figure 2 . Figure 5 , a sewage treatment device, including a sewage tank 1, a water inlet tank 2 is opened at the top of the sewage tank 1, a filter plate 3 for filtering sewage impurities is fixedly installed inside the sewage tank 1, a collection tank 4 for collecting impurities is clamped on one side of the filter plate 3, a stirring structure 5 for stirring sewage condensation is installed at the bottom end of the filter plate 3, and a cleaning structure 6 for scraping impurities on the surface of the filter plate 3 is slidably installed on the top surface of the filter plate 3;

[0024] The cleaning structure 6 includes a threaded rod 600, which is installed on the top of the filter plate 3. A movable block 601 is sleeved on the outer wall of the threaded rod 600. The number of movable blocks 601 is set to two and they are symmetrically and evenly distributed at both ends of the threaded rod 600. Threaded grooves are provided on the outer surfaces of both ends of the threaded rod 600, and the rotation directions of the threaded grooves at both ends are opposite, so as to enable the two movable blocks 601 to move relatively synchronously. A push rod 602 is rotatably connected to the inside of the movable block 601 through a shaft rod. A scraper 604 for scraping impurities is rotatably installed at one end of the push rod 602 away from the movable block 601. Specifically, the push rod 602 and the scraper 604 are rotatably connected through a connecting member 603;

[0025] A scraping blade 605 is fixedly connected to the bottom end of the scraper 604. The material of the scraping blade 605 is set to silicone and it is in contact with the surface of the filter plate 3;

[0026] Specifically, the filter plate 3 is set at a certain inclination angle. When the push rod 602 pulls the scraper 604 close to the threaded rod 600, the scraping blade 605 gradually moves away from the filter plate 3, creating a gap between the two, so as to facilitate the continuous reciprocating movement of the scraper 604;

[0027] One end of the threaded rod 600 is rotatably connected to the inside of the sewage tank 1 through a bearing, and the other end is fixedly connected to a motor 606 for providing the rotational power of the threaded rod 600. The motor 606 is located on the outer wall of the sewage tank 1, and the output end of the motor 606 is fixedly connected to one end of the threaded rod 600. A moving groove for providing the movement of the movable block 601 is provided on the inner wall of the sewage tank 1, and the movable block 601 is located in the moving groove.

[0028] Please refer to Figure 2 、 Figure 5 , a plurality of water filtering holes 401 for discharging sewage are provided on the inner wall of the collection box 4. A sliding block 402 is fixedly installed on the outer wall of the collection box 4. A sliding groove for providing the sliding of the sliding block 402 is provided on the inner wall of the sewage tank 1, and the sliding block 402 is located in the sliding groove, so as to facilitate the extraction, cleaning and replacement of the collection box 4.

[0029] Embodiment 2: Please refer to Figure 2 、 Figure 3 - Figure 4 , the stirring structure 5 includes a rotating rod 501. A rotating blade 502 is sleeved on the outer wall of the rotating rod 501. A rotating rod 503 is installed at the bottom end of the rotating rod 501. A plurality of stirring blades 504 for stirring and mixing sewage are fixedly installed on the outer wall of the rotating rod 503;

[0030] Specifically, both the rotating rod 501 and the rotary rod 503 are rotatably connected to the inner wall of the sewage tank 1 through bearings at both ends, and snap rings 505 are sleeved on the outer walls of both. The rotating rod 501 and the rotary rod 503 are rotatably connected by a belt 506, and the belt 506 is located within the snap ring 505. There are two rotary rods 503 in total, which are symmetrically and evenly distributed on both sides of the bottom end of the rotating rod 501.

[0031] To ensure that the rotating blade 502 can have sufficient power to drive the rotation of the rotating rod 501, a flow guide plate 507 is fixedly installed at the top of the rotating rod 501. The flow guide plate 507 is set at a certain inclination angle, and a flow guide groove is opened inside it to facilitate guiding the flowing water towards the axis of the sewage tank 1. A baffle 508 for accumulating sewage is rotatably installed on one side of the flow guide plate 507 close to the axis of the sewage tank 1.

[0032] Specifically, the baffle 508 is perpendicular to the flow guide plate 507, and the two are connected by a spring 509 for resetting. By accumulating a certain amount of sewage on the baffle 508 until it is greater than the pulling force of the spring 509, the baffle 508 is pushed to flip. The falling sewage drives the rotating blade 502 to drive the rotation of the rotating rod 501, and then the spring 509 pulls the baffle 508 back to its original position to continue blocking the sewage flow.

[0033] More specifically, to ensure that the rotating rod 501 can still rotate when the water energy of the falling sewage is insufficient, one end of the rotating rod 501 is fixedly connected to a driving motor 510, and the driving motor 510 is located on the outer wall of the sewage tank 1.

[0034] Please refer to Figure 1 - Figure 2 As shown in, a water storage tank 7 is fixedly installed on the outer wall of the sewage tank 1. A spray head 8 for spraying flocculant is fixedly installed on one side of the water storage tank 7, and the spray head 8 is located on the inner wall of the sewage tank 1.

[0035] Please refer to Figure 1 As shown in, a drain pipe 9 is fixedly installed on one side of the sewage tank 1. A water pump 10 is sleeved on the outer wall of the drain pipe 9. A water bucket 11 is fixedly installed at one end of the drain pipe 9. A sewage discharge pipe 12 is fixedly connected to the outer wall of the sewage tank 1.

[0036] The working principle of the present utility model is:

[0037] First, sewage is injected into the sewage tank 1 through the water inlet tank 2. The impurities in the sewage are filtered by the filter plate 3. The starting motor 606 is connected to the threaded rod 600 to rotate, causing the two sets of movable blocks 601 to move along the threaded rod 600 towards its center, driving the push rod 602 to rotate, and through the connecting piece 603, pushing the two sets of scraping plates 604 and scraping blades 605 to push the impurities on the filter plate 3 into the collection box 4. When the push rod 602 pulls the scraping plate 604 close to the threaded rod 600, the scraping blade 605 gradually moves away from the filter plate 3, creating a gap between the two, so that the scraping plate 604 can continuously move back and forth. After a certain amount is collected, the collection box 4 is pulled upwards, allowing the sliding block 402 to move smoothly upwards along the sliding groove, facilitating the extraction, cleaning, and replacement of the collection box 4. Then, the filtered sewage flows down into the guide plate 507, guiding the sewage to flow towards the center of the sewage tank 1. A certain amount of sewage is accumulated by the baffle 508 until it is greater than the pulling force of the spring 509, pushing the baffle 508 to flip. The falling sewage drives the rotating blade 502 to drive the rotating rod 501 to rotate, and then the spring 509 pulls the baffle 508 back to its original position to continue blocking the sewage flow. The nozzle 8 sprays the flocculant to react with the sewage at the bottom of the sewage tank 1. The rotating rod 501 is connected to the belt 506 to drive the two sets of rotating rods 503 to rotate, causing the stirring blades 504 to rotate accordingly, stirring and mixing the sewage in the sewage tank 1. Finally, after a period of precipitation, the clear water is pumped into the water bucket 11 for storage by the water pump 10 connected to the drain pipe 9, and the sewage inside the sewage tank 1 is discharged through the sewage pipe 12.

[0038] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, should be covered within the protection scope of the present utility model.
