[0002] Wastewater treatment refers to the use of physical, chemical, and biological methods to purify wastewater, reduce pollution, and achieve the goal of wastewater recycling and reuse. Wastewater treatment is widely used for treating urban sewage and industrial wastewater. Urban sewage mainly originates from domestic drainage, while industrial wastewater comes from various production processes. Effective wastewater treatment can reduce pollution, protect the environment, and simultaneously achieve water resource recycling and reuse, resulting in significant environmental and economic benefits.

[0003] Existing wastewater treatment filtration devices are designed with static filters, which are prone to clogging during the wastewater filtration process, thus affecting the filtration efficiency. Therefore, a new wastewater treatment filtration device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment filtration device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment filtration device, comprising a wastewater treatment cylinder, a filtration device disposed inside the wastewater treatment cylinder, the filtration device comprising a support ring, a drive motor fixedly connected to the top of the support ring, a rotating rod fixedly connected to the output end of the drive motor, a guide ring fixedly connected to the inner wall of the wastewater treatment cylinder, four connecting rods fixedly connected to the surface of the rotating rod, scrapers fixedly connected to one end of each of the four connecting rods, a filter screen fixedly connected to the surface of the rotating rod, a rotating connecting rod fixedly connected to the bottom of the filter screen, a bearing rotatably connected to the surface of the rotating connecting rod, four fixed columns fixedly connected to the surface of the bearing, multiple arc-shaped guide push plates fixedly connected to the top of the filter screen, a slip ring fixedly connected to the surface of the filter screen, a collecting ring slidably connected to the surface of the slip ring, a connecting pipe fixedly connected to the bottom of the collecting ring, and a sewage pump fixedly connected to one end of the connecting pipe.

[0006] By setting up the above structure, in order to ensure the filtration effect of the filter screen, the drive motor synchronously drives the scraper, filter screen and arc-shaped guide pusher to rotate. The rotation of the scraper can effectively scrape off the wastewater impurities attached to the guide ring, ensuring that the wastewater flows smoothly into the filter screen through the guide ring. The rotation of the filter screen allows it to contact the wastewater over a large area, making full use of the filtration area, reducing clogging and improving the filtration efficiency of the wastewater. At the same time, the arc-shaped guide pusher applies a pushing force to the wastewater, promoting the wastewater to flow through the filter screen more quickly and evenly and to penetrate smoothly. In addition, the centrifugal force generated by the rotation of the filter screen and the synergistic effect of the arc-shaped guide pusher can push the wastewater impurities into the collection ring for unified treatment.

[0007] As a preferred embodiment, the surface of the wastewater treatment cylinder is provided with a limiting ring, the surface of the limiting ring is provided with four supporting legs, and the interior of the wastewater treatment cylinder is provided with a treatment cavity.

[0008] As a preferred embodiment, the wastewater treatment cylinder has an inlet at the top and an outlet at the bottom.

[0009] As a preferred embodiment, the bottom of the support ring is fixedly connected to the top of the wastewater treatment cylinder, and the rotating rod rotates inside the wastewater treatment cylinder.

[0010] As a preferred embodiment, the scraper is fitted to the inner wall of the guide ring, and one end of each of the four fixed columns is fixedly connected to the inner wall of the wastewater treatment cylinder.

[0011] As a preferred embodiment, the surface of the collecting ring is fixedly connected to the inner wall of the wastewater treatment cylinder, and the connecting pipe penetrates the wastewater treatment cylinder.

[0012] By setting up a flow guide ring, the wastewater can be effectively guided to flow along a specific path, avoiding turbulence during the treatment process and ensuring that the wastewater can flow to the filter screen in an orderly and efficient manner, thereby maximizing the efficiency and quality of wastewater treatment.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by incorporating a drive motor, scraper, filter screen, and arc-shaped guide plate, ensures the filtration effect of the filter screen. The drive motor synchronously drives the scraper, filter screen, and arc-shaped guide plate to rotate. The rotation of the scraper effectively removes wastewater impurities adhering to the guide ring, ensuring that wastewater flows smoothly through the guide ring into the filter screen. The rotation of the filter screen allows it to contact the wastewater over a large area, fully utilizing the filtration area, reducing clogging, and improving filtration efficiency. Simultaneously, the arc-shaped guide plate applies a pushing force to the wastewater, promoting faster and more even flow through the filter screen and facilitating penetration. Furthermore, the centrifugal force generated by the rotation of the filter screen, combined with the synergistic effect of the arc-shaped guide plate, pushes wastewater impurities into a collection ring for unified treatment.

[0015] This invention, by setting a flow guide ring, can effectively guide wastewater to flow along a specific path, avoid turbulence during the treatment process, and ensure that the wastewater can flow to the filter screen in an orderly and efficient manner, thereby maximizing the efficiency and quality of wastewater treatment.

A connecting pipe 714 is fixedly connected to the bottom of ring 713, and a sewage pump 715 is fixedly connected to one end of the connecting pipe 714. By configuring a drive motor 702, scraper 706, filter screen 707, and arc-shaped guide plate 711, the drive motor 702 synchronously drives the scraper 706, filter screen 707, and arc-shaped guide plate 711 to rotate in order to ensure the filtration effect of the filter screen 707. The rotation of the scraper 706 effectively scrapes away wastewater impurities attached to the guide ring 704, ensuring smooth wastewater flow. The wastewater flows into the filter screen 707 through the guide ring 704. The rotation of the filter screen 707 allows it to contact the wastewater over a large area, making full use of the filtration area, reducing clogging, and improving the filtration efficiency of the wastewater. At the same time, the arc-shaped guide push plate 711 applies a pushing force to the wastewater, promoting the wastewater to flow through the filter screen 707 more quickly and evenly, and to penetrate smoothly. In addition, the centrifugal force generated by the rotation of the filter screen 707 and the synergistic effect of the arc-shaped guide push plate 711 can push the wastewater impurities into the collection ring 713 for unified treatment.

[0025] The surface of the wastewater treatment cylinder 1 is provided with a limiting ring 2, and the surface of the limiting ring 2 is provided with four supporting legs 3. The interior of the wastewater treatment cylinder 1 is provided with a treatment chamber 4.

[0028] The scraper 706 is attached to the inner wall of the guide ring 704, and one end of each of the four fixed columns 710 is fixedly connected to the inner wall of the wastewater treatment cylinder 1.

[0029] The surface of the collecting ring 713 is fixedly connected to the inner wall of the wastewater treatment cylinder 1, and the connecting pipe 714 passes through the wastewater treatment cylinder 1. By setting the guide ring 704, the guide ring 704 can effectively guide the wastewater to flow along a specific path, avoid turbulence in the wastewater during the treatment process, and ensure that the wastewater can flow to the filter screen 707 in an orderly and efficient manner, thereby maximizing the efficiency and quality of wastewater treatment.

[0030] The working principle and usage process of this utility model are as follows: To ensure the filtration effect of the filter screen 707, the drive motor 702 is started to drive the rotating rod 703 to rotate. The rotation of the rotating rod 703 will synchronously drive the scraper 706, the filter screen 707 and the arc-shaped guide push plate 711, so that they work together. The rotation of the scraper 706 acts on the guide ring 704, effectively scraping off the attached wastewater impurities, ensuring that the wastewater can flow smoothly into the filter screen 707 through the guide ring 704. The rotation of the filter screen 707 allows it to contact the wastewater over a large area, making full use of the filtration area and reducing clogging. The arc-shaped guide push plate 711 applies a pushing force to the wastewater, promoting the wastewater to flow through the filter screen 707 more quickly and evenly. In addition, the centrifugal force generated by the rotation of the filter screen 707 and the synergistic effect of the guide push plate push the wastewater impurities into the collection ring 713 for unified treatment. Finally, the sewage pump 715 extracts the wastewater impurities from the collection ring 713 through the connecting pipe 714.
