[0002] A self-circulating short-range digestion wastewater treatment device is a type of equipment that uses the principle of anaerobic digestion to treat domestic wastewater. During the treatment process, it decomposes the organic matter in the wastewater into usable resources, such as biogas, through natural circulation, and effectively reduces the pollutant content in the wastewater. This device is particularly suitable for the treatment of small and medium-sized domestic wastewater and is widely used in rural areas, suburbs, and some small communities or places that are not connected to a centralized wastewater treatment system.
[0003] In some existing wastewater treatment systems, there is a filtration mechanism. When this mechanism is in use, impurities often float on its surface and need to be cleaned manually. As the impurities continue to grow, they need to be cleaned manually multiple times, which reduces the efficiency of impurity removal.
[0004] In summary, this application proposes a small-scale self-circulating short-range digestion domestic sewage treatment device to solve the aforementioned problems. Utility Model Content

Compared with the traditional fixed type, it reduces the time spent on manual impurity handling and improves the effectiveness of the device.
[0012] Preferably, both the self-circulating treatment pool and the collection box have rectangular openings, which facilitate the accumulation of impurities falling into the rectangular openings.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] Please see Figure 1-3This utility model provides a technical solution: a small-scale self-circulating short-range digestion domestic sewage treatment device, including a self-circulating treatment tank 1, a moving component, and a treatment component. A collection box 2 is installed on the self-circulating treatment tank 1. A trapezoidal grid 3 is fixedly connected inside the self-circulating treatment tank 1. Because the trapezoidal grid 3 is designed in a grid format, it can filter large impurities in the sewage. A filter screen 4 is fixedly connected to the inner side of the self-circulating treatment tank 1, which facilitates the filtration of smaller impurities. Grooves are opened on both sides of the self-circulating treatment tank 1, the positions of which correspond to the filter screen 4. This arrangement allows workers to clean the filter screen 4 using tools through the grooves. Mounting plates 5 are fixedly connected to the front and rear sides of the self-circulating treatment tank 1, which facilitates the installation of the moving component. The moving assembly, located on the self-circulating treatment tank 1, includes a bidirectional threaded rod 6, a motor 7, a connecting crank 8, and a push plate 9. The bidirectional threaded rod 6 is rotatably mounted on a mounting plate 5 located at the front of the self-circulating treatment tank 1. Two sets of connecting cranks 8 are threaded onto the outer wall of the bidirectional threaded rod 6 and are arranged opposite each other. Two sets of push plates 9 are also arranged opposite each other, with the top of each push plate 9 fixedly connected to one end of the connecting crank 8. An auxiliary rod is fixedly mounted on the mounting plate 5 located at the rear, and the mounting plate 5 on the auxiliary rod is slidably mounted on its outer wall. During use, wastewater enters the self-circulating treatment tank 1 through the trapezoidal screen 3 and undergoes filtration. Then, the wastewater undergoes secondary filtration through a filter screen 4. After filtration, large impurities remain in the trapezoidal screen 3. Simultaneously, the motor 7 is started, and the output shaft of the motor 7 drives the bidirectional threaded rod 6 to rotate. The bidirectional threaded rod 6 drives the two sets of connecting cranks 8 to move relative to each other. The two sets of connecting cranks 8 slide on the auxiliary rod, and the connecting cranks 8 drive the push plate 9 to move relative to each other. The push plate 9 pushes the impurities on the trapezoidal screen 3 to both sides. Through the coordinated use of the bidirectional threaded rod 6, the motor 7, the connecting cranks 8, and the push plate 9, the impurities remaining on the trapezoidal screen 3 can be pushed, reducing the occurrence of impurities clogging the trapezoidal screen 3 and avoiding the impact on sewage filtration. Moreover, by pushing the impurities, they are moved, making it easier for the impurities to be collected and cleaned later. The treatment component is located on the self-circulating treatment tank 1 and the collection box 2. The treatment component includes a cylindrical... 10. A lever plate 11, mounting columns 12, and a circular plate 13 are fixedly connected to the front and rear sides of the self-circulating treatment tank 1, arranged opposite each other. Lever plates 11 are hinged to the columns 10. Mounting columns 12 are fixedly connected to the front and rear sides of the collection box 2. A circular plate 13 is fixedly connected to the front side of the mounting columns 12. Lever plates 11 have notches, which engage with the mounting columns 12. The circular plate 13 contacts the lever plate 11. When impurities are pushed to both sides of the trapezoidal grid 3, they accumulate towards the rectangular opening 14 under the inclination and fall into the collection box 2. After the impurities in the collection box 2 are collected, the lever plate 11 is moved, causing the notch on the lever plate 11 to disengage from the circular plate 13, separating the self-circulating treatment tank 1 from the collection box 2. Then, the circular plate 13 is manually dragged.The collection box 2 is moved to facilitate the cleaning of impurities. Through the coordinated use of the cylinder 10, the lever 11, the mounting column 12, and the circular plate 13, the collection box 2 can be moved, making it easier to clean accumulated impurities. This prevents impurities from scattering in various areas, thus avoiding complex and tedious cleaning work. It allows operators to perform maintenance and cleaning more efficiently, ensuring the long-term efficient operation of the device. Compared to traditional fixed systems, this reduces the time spent manually handling impurities and improves the overall effectiveness of the device.
[0023] Furthermore, both the self-circulating treatment pool 1 and the collection box 2 are provided with rectangular openings 14, which are designed to facilitate the falling of accumulated impurities into the rectangular openings 14.
[0024] Working principle: During use, sewage enters the self-circulating treatment tank 1 through the trapezoidal screen 3. The sewage undergoes filtration through the trapezoidal screen 3, and then undergoes secondary filtration through the filter screen 4. After filtration, large impurities remain on the trapezoidal screen 3. At the same time, the motor 7 is started, and the output shaft of the motor 7 drives the bidirectional threaded rod 6 to rotate. The bidirectional threaded rod 6 drives the two sets of connecting cranks 8 to move relative to each other. The two sets of connecting cranks 8 slide on the auxiliary rod. The connecting cranks 8 drive the push plate 9 to move relative to each other. The push plate 9 pushes the impurities at the flat part of the trapezoidal screen 3 to both sides. When the impurities are pushed to both sides of the trapezoidal screen 3, they accumulate towards the rectangular opening 14 under the action of inclination and fall into the collection box 2. After the impurities in the collection box 2 are collected, the notch on the dial plate 11 is disengaged from the circular plate 13 by moving the dial plate 11, separating the self-circulating treatment tank 1 from the collection box 2. Then, the circular plate 13 is manually dragged to move the collection box 2, which facilitates the cleaning of impurities.
[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
