[0002] Residents generate a large amount of wastewater in their daily lives. In order to avoid the impact of wastewater on the environment, wastewater is treated through treatment tanks.

[0003] According to CN213680079U, a wastewater treatment filter tank for urban domestic sewage includes a tank body, a fixed frame, and a base. The upper end of the tank body is fixedly connected to the sewage inlet. Wastewater treated through two processes is discharged to the outside through an outlet pipe. Under the action of a guide plate, the wastewater can be evenly sprayed onto the surface of the anthracite filter media. The aforementioned document filters the wastewater using both anthracite and quartz sand filter media on the guide plate, causing impurities to accumulate on the guide plate. Since the guide plate is fixedly installed inside the tank, it cannot be removed, making cleaning inconvenient. Furthermore, the one-piece molded tank structure makes it easy for impurities to remain on the inner wall of the tank, compromising the cleanliness of the tank. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A municipal sewage treatment tank includes a cleaning tank, which is composed of a tank body 1, a filter frame 7, a motor 8, a drive rod 9, and a stirring rod 10. When the motor 8 is powered on, it drives the drive rod 9 and the stirring rod 10 to rotate, so that the stirring rod 10 can stir the sewage and disinfectant.

[0022] The tank body 1 is provided with a cover 2, and a sleeve 3 is fixedly installed inside the tank body 1. An installation rod 4 is installed inside the sleeve 3, and the two installation rods 4 are integrally connected to a frame 5 for filtering sewage. By providing a cover 2 on the tank body 1, the operator can clean the inside of the tank body 1 after the cover 2 is disconnected from the tank body 1.

[0023] The sleeve 3 is vertically installed on both sides of the tank body 1, and the sleeve 3 is an annular structure with an open top. The frame 5 and the mounting rod 4 extend to the upper end of the sleeve 3. The mounting rod 4 is threaded with a fixing bolt connected to the sleeve 3. The mounting rod 4 is positioned by the sleeve 3 so that the frame 5 can be installed inside the tank body 1. The mounting rod 4 is installed by the sleeve 3, which allows the frame 5 to be removed from the tank body 1, further maintaining the cleanliness of the frame 5.

[0024] A filter screen 6 for filtering sewage is connected to the frame 5 by screws. A filter frame 7 is set on the frame 5, and a filter layer for filtering sewage is laid inside the filter frame 7. The filter layer consists of a quartz sand layer, a fruit shell filter layer, a granular activated carbon layer, and filter cotton. A connecting ear extending to the frame 5 is fixedly installed on the filter frame 7, and a fixing bolt connected to the frame 5 is threaded on the connecting ear. The laying of the quartz sand layer can intercept impurities such as suspended solids, organic matter, colloids, and silt. The laying of the fruit shell filter layer can intercept oil in the sewage, and the fruit shell filter layer is low in cost and easy to replace. The laying of the granular activated carbon layer can intercept organic matter in the sewage. It can effectively intercept impurities in the sewage and achieve the purpose of purifying sewage.

[0025] The drive rod 9 is vertically arranged, and the stirring rod 10 and the drive rod 9 extend to the upper part of the tank 1. The stirring rod 10 is fixedly installed with a support plate 11 and a support plate 12. The support plate 11 is fixedly installed with a cleaning plate 13 for cleaning the outer wall of the frame 5, and the support plate 12 is fixedly installed with a cleaning plate 14 for cleaning the inner wall of the tank 1. When the cleaning plate 13 rotates, it can scrape the outer wall of the frame 5, thereby maintaining the flow of sewage. When the cleaning plate 14 rotates, it scrapes the inner wall of the tank 1, thereby ensuring the cleanliness of the inside of the tank 1.

[0026] The cover 2 is provided with a cleaning structure for cleaning the inner wall of the frame 5.

[0027] The cleaning structure includes a ring frame 15 slidably fitted onto the cover 2, with a ring-shaped rack 16 and a scraper 20 for cleaning the inner wall of the frame 5 fixedly mounted on the ring frame 15. A second motor 17 is fixedly mounted on the cover 2, and the output end of the second motor 17 is fixedly connected to a rotating shaft 18 that is driven by the ring-shaped rack 16. The ring frame 15 has a ring-shaped structure, the rotating shaft 18 is vertically arranged, and a gear 19 that meshes with the ring-shaped rack 16 is fixedly mounted on the rotating shaft 18. The cover 2 guides the ring frame 15, limiting the movement direction of the ring-shaped rack 16 and the scraper 20 when the ring frame 15 moves. When the scraper 20 rotates, it can scrape the inner wall of the frame 5, removing impurities attached to the inner wall of the frame 5, thereby improving the efficiency of sewage filtration.

[0028] It should be noted that the specific model and specifications of motor 18 and motor 217 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] Wastewater enters tank 1 through the inlet;

[0031] When the sewage flows inside the tank 1, it will pass through the frame 5, filter screen 6, filter layer and filter frame 7 in sequence, which can intercept impurities in the sewage.

[0032] At the same time, the output end of motor 17 drives the rotating shaft 18 to rotate, and the rotating shaft 18 drives the gear 19 to pull the meshing ring rack 16, so that the ring rack 16 drives the ring frame 15 to rotate on the cover 2. When the ring frame 15 rotates, it drives the scraper 20 to scrape the inner wall of the frame 5.

[0033] Disinfectant is put into tank 1. The output end of motor 8 drives drive rod 9 to rotate. Drive rod 9 drives stirring rod 10 to stir sewage and disinfectant. Stirring rod 10 drives support plate 11 and support plate 2 to rotate. Support plate 11 drives cleaning plate 13 to clean the outer wall of frame 5. Support plate 2 drives cleaning plate 2 14 to clean the inner wall of tank 1.

[0034] When it is necessary to clean the frame 5, remove the cover 2, and then remove the frame 5, filter screen 6, and filter frame 7 for cleaning.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
