DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a multi-layer filter manhole cover structure for municipal drainage provided by the utility model; Figure 2 for Figure 1 A schematic bottom view of the structure shown; Figure 3 for Figure 1 The schematic cross-sectional view of the structure shown; Figure 4 for Figure 3 The schematic diagram of the partial structure shown. The multi-layer filter manhole cover structure for municipal drainage includes: a manhole cover 3, a base 8 is fixedly installed at the bottom of the manhole cover 3, two filter plates 6 are arranged in the base 8, and the two filter plates 6 can intercept debris, particles and pollutants of different sizes and types in layers and grades, an annular fixing seat 4 is fixedly installed on the top of the manhole cover 3, a second cover plate 5 is arranged on the top of the annular fixing seat 4, and the second cover plate 5 is hinged on the annular fixing seat 4, four cleaning ports are arranged on the manhole cover 3, and the first cover plate 2 is hinged on the manhole cover 3, four placement boxes 1 are fixedly installed at the bottom of the manhole cover 3, and dust collecting seats 13 are arranged in the four placement boxes 1, and handles 10 are fixedly installed in the dust collecting seats 13, a plurality of third flow ports 16 are arranged on the base 8, the first flow ports 12 are arranged on the four placement boxes 1, and the second flow ports 15 are arranged on the four dust collecting seats 13.

[0022] Four fixing columns 11 are fixedly installed at the bottom of the annular fixing seat 4, and the other ends of the four fixing columns 11 are fixedly connected to the manhole cover 3. While the four fixing columns 11 support the annular fixing seat 4, rainwater can enter the base 8 from the drainage port between the annular fixing seat 4 and the manhole cover 3.

[0023] The four placement boxes 1 are respectively located at the bottom of the four cleaning openings.

[0024] The third flow port 16 , the first flow port 12 , and the second flow port 15 are all connected. When the debris rolls around the filter plate 6 , the debris can quickly enter the dust collecting seat 13 through the third flow port 16 , the first flow port 12 , and the second flow port 15 .

[0025] The two filter plates 6 are both provided with a fourth water outlet 17 .

[0026] The bottom and both sides of the dust collecting seat 13 are respectively provided with a third water outlet 14 and a second water outlet 9. When too much debris accumulates in the dust collecting seat 13, the second water outlet 9 and the third water outlet 14 can quickly discharge the sewage in the debris to avoid excessive debris and sewage affecting the cleaning of the staff.

[0027] The two filter plates 6 are both conical. Setting the two filter plates 6 into a cone shape allows debris to roll to the four sides of the filter plates 6, making it convenient for debris to enter the dust collecting seat 13 and avoiding the debris from being concentrated in the middle of the filter plates 6, which affects the drainage efficiency and applies pressure to the filter plates 6.

[0028] The working principle of the multi-layer filter manhole cover structure for municipal drainage provided by the utility model is as follows:

[0029] First, the sewage enters the base 8 through the drain port between the annular fixing seat 4 and the manhole cover 3. At this time, when the sewage passes through the two filter plates 6, the larger particles and debris in the sewage are filtered out by the filter plates 6, and the remaining sewage is discharged into the sewer, while the larger particles and debris will roll around the filter plates 6 and enter the manhole cover 3 through the third flow port 16, the first flow port 12 and the second flow port 15. When debris accumulates in the manhole cover 3, the second water outlet 9 and the third water outlet 14 can filter the debris and sewage again. When it is necessary to clean the debris in the dust collecting seat 13, open the four first cover plates 2 on the dust collecting seat 3, and take the dust collecting seat 13 out of the placement box 1 by pulling the handle 10. In this way, the debris concentrated in the dust collecting seat 13 can be cleaned. When the filter plate 6 needs to be replaced, open the second cover plate 5 on the top of the annular fixing seat 4 to avoid debris concentrating on the filter plate 6 and causing blockage.

[0030] Compared with the related art, the multi-layer filter manhole cover structure for municipal drainage provided by the utility model has the following beneficial effects:

[0031] The utility model provides a multi-layer filter manhole cover structure for municipal drainage. Through the cooperation of the manhole cover 3, the first cover plate 2, the annular fixing seat 4, the second cover plate 5 and the fixing column 11, when the second cover plate 5 and the first cover plate 2 are opened, daily cleaning and maintenance can be more convenient. Secondly, the sundries and silt accumulated in the placement box 1 can be easily cleaned to ensure the continuous good filtering effect; through the cooperation of the placement box 1, the first water outlet 7, the second flow port 15, the dust collecting seat 13, the second water outlet 9 and the handle 10, when the sundries slide into the dust collecting seat 13 through the filter plate 6, the dust collecting seat 13 can collect a large amount of sundries and The fourth water outlet 17, the filter plate 6, the base 8 and the third flow port 16 cooperate with each other, and the two filter plates 6 can intercept different sizes and types of debris, particles and pollutants in layers and grades, thereby greatly improving the ability to remove impurities in sewage and effectively reducing pollutants entering the drainage pipe.
