However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] Reference Figure 1-4 As shown: a municipal drain outlet filtering device with a filtering function, including a filter box 4, a cover plate 1 is clamped on the top of the filter box 4, a rectangular hole is opened on the top of the cover plate 1, and one side of the filter box 4 is fixedly connected with a drain pipe 5, and one side of the drain pipe 5 is provided with an auxiliary mechanism, the auxiliary mechanism includes a limit clamp 2, a connector 9 and a limit clamp 20, the limit clamp 2 and the limit clamp 20 are connected by bolts, one side of the limit clamp 20 is slidably connected with a guide plate 3, one side of the guide plate 3 is fixedly connected to the filter box 4, one side of the inner wall of the filter box 4 is fixedly connected with an elastic sealing ring 19, the outer ring surface of the elastic sealing ring 19 is fixedly connected to the connector 9, and the inner ring surface of the connector 9 is fixedly connected with a dividing knife 16.

[0024] An internal block 6 is fixedly connected to the bottom of the inner cavity of the filter box 4 , and a collecting basket 7 is arranged on the top of the internal block 6 . The collecting basket 7 is slidably connected to the filter box 4 .

[0025] The rectangular hole on the top of the cover plate 1 can accelerate the air flow inside the filter box 4, thereby avoiding the accumulation of odor inside the filter box 4. The drain pipe 5 is located between the two built-in blocks 6. The two built-in blocks 6 can assist the accumulation of filtered water at the bottom of the inner cavity of the filter box 4. The water flow can be quickly discharged through the drain pipe 5. The limit clamp 1 2 and the limit clamp 2 20 are both arc-shaped, and their inner walls can fit with the outer ring surface of the pipeline. The bolts between the limit clamp 1 2 and the limit clamp 20 can be rotated to change the distance between the limit clamp 1 2 and the limit clamp 20, so as to lock and fix the pipeline. The elastic sealing ring 19 is sleeved on the outside of the pipeline, and the end of the pipeline It is sleeved inside the connector 9, and the thickness of the inner wall of the connector 9 is thicker on the side close to the elastic sealing ring 19 and thinner away from the elastic sealing ring 19. Therefore, the water discharged through the pipe can be quickly discharged after entering the connector 9. There are two groups of dividing knives 16, three in each group, and the three dividing knives 16 are distributed at 120° intervals, and the two groups of dividing knives 16 are staggered. The sewage and internal impurities are discharged before the dividing knives 16. The flowing sewage can generate thrust on the impurities, thereby accelerating the crushing of the impurities and reducing the volume of the impurities. The treated impurities are discharged with the sewage, thereby avoiding blockage inside the connector 9. Example

[0026] like Figure 1-Figure 4 As shown, a support plate 10 is fixedly connected to the inner wall of the filter box 4 , a filter screen 12 is embedded inside the support plate 10 , and a buffer plate 8 is fixedly connected to the top of the support plate 10 .

[0027] The bottom of the support plate 10 is connected to a filter screen 11 via a spring, and the filter screen 11 has an arc-shaped longitudinal section.

[0028] A scraper 18 is slidably connected to the top of the support plate 10 , a rack 15 is fixedly connected to one side of the scraper 18 , and a gear 14 is meshed with the bottom of the rack 15 .

[0029] The gear 1 14 is rotationally connected to the filter box 4 , and one side of the gear 1 14 is meshed with the gear 2 17 , and one side of the gear 2 17 penetrates the side wall of the filter box 4 .

[0030] One side of the gear 2 17 is fixedly connected to the output shaft of the motor 13 , and one side of the motor 13 is fixedly connected to the filter box 4 .

[0031] The support plate 10 is connected with the two filter nets 12 to facilitate the installation and use of the filter net 12 by the support plate 10. The sewage above the support plate 10 can be initially filtered through the filter net 12. The filter net 11 and the support plate 10 are connected by a spring. When the sewage passes through the filter net 12, a force is applied to the filter net 11. The spring is elastically deformed to drive the filter net 11 to move downward, change the distance between the filter net 11 and the filter net 12, and use the filter net 12 to filter the sewage again. There are two scrapers 18, both of which are arranged on one side of the two filter screens 12. The motor 13 can be driven regularly by an external control switch, and the motor 13 drives the gear 2 17 to rotate. Since the gear 2 17 is meshed with the gear 1 14, the gear 14 can rotate when the gear 2 17 rotates, thereby driving the rack 15 and the scraper 18 to move synchronously. When the scraper 18 moves, the impurities remaining on the top of the filter screen 12 can be scraped off, and the scraped impurities fall into the collection basket 7 for collection, without the need to manually disassemble the filter structure for cleaning.

[0032] The method of use and working principle of the device are as follows: first, insert the water inlet pipe through the elastic sealing ring 19 and the connector 9, then move the limit clamp 20 between the two guide plates 3, adjust the distance between the two limit clamps 20, and then install bolts between the limit clamp 20 and the limit clamp 1 2, fix the limit clamp 1 2 and the limit clamp 20, so as to clamp and fix the water inlet pipe, and the sewage enters the connector 9 through the inlet pipe, and the larger impurities in the sewage can be broken by the dividing knife 16, and the processed debris and impurities are discharged from the connector 9 and fall after being buffered by the buffer plate 8. On the support plate 10, it is then filtered by the filter screen 2 12 and the filter screen 1 11 in turn and collected at the bottom of the inner cavity of the filter box 4, and finally discharged through the drain pipe 5. The impurities and debris remain on the filter screen 2 12. The motor 13 drives the gear 2 17 to rotate, and the gear 17 drives the gear 14 to rotate. The gear 14 engages with the rack 15 to drive the rack 15 and the scraper 18 to reciprocate on the top of the filter screen 2 12, and the debris on the filter screen 2 12 is scraped into the collection basket 7. The collection basket 7 can be pulled out at the end of the mobile collection basket 7, and the impurities inside the collection basket 7 are cleaned regularly.
