The top ring 51 and the bottom ring 52 are coaxial and connected by a plurality of elastic ropes 53 arranged in a ring with their axes as references, and the inner and outer diameters of the top ring 51 and the bottom ring 52 are the same. An annular filter screen 54 is fixedly connected between the top ring 51 and the bottom ring 52 and on the inner side of each elastic rope 53.

[0021] The diameter of the annular filter screen 54 is greater than the diameter of the top ring 51 , and the elastic rope 53 constrains the annular filter screen 54 so that its cross section is gear-shaped.

[0022] See also Figure 3 The driving mechanism 6 includes a cylinder 61, a motor housing 62, a driving motor 63 and a rotating shaft 64. The cylinder 61 is fixedly mounted on the upper surface of the housing 1.

[0023] See also Figure 2 , 4The cleaning mechanism 7 includes a cross bar 71, an insertion rod 72, a sealed pressure ring 73, a compression spring 74, a mounting ring 75, a spring leaf 76 and a mud scraper rubber ring 77.

[0024] The number of filtering mechanisms 5 is not less than four and is arranged in a matrix between partition 1 8 and partition 2 9 . The number of inserting rods 72 is less than the number of filtering mechanisms 5 . After the rotating shaft 64 drives the cross bar 71 to rotate, the inserting rods 72 can clean different filtering mechanisms 5 .

[0025] The upper and lower surfaces of the reed 76 are perpendicular to the axis of the mounting ring 75. The thickness of the scraper rubber ring 77 decreases from the middle to the edge. The decreasing thickness design helps the scraper rubber ring 77 to push the sludge to open the sealing rubber ring 56. During normal filtering operation, the sealing rubber ring 56 is in a closed state. When the scraper rubber ring 77 is pressed against the sealing rubber ring 56, the hole in the middle of the sealing rubber ring 56 will be expanded under pressure, so that the scraper rubber ring 77 carries the sludge through the mud outlet 11.

[0026] The edge of the scraper rubber ring 77 is provided with annularly arranged tooth grooves 14, the number of which is the same as the number of the elastic ropes 53. The diameter of the scraper rubber ring 77 is larger than the inner diameter of the top ring 51, and the bottom of the scraper rubber ring 77 is provided with a dirt collecting groove 20 for providing space for storing mud when scraping mud.

[0027] A mounting groove 15 is provided on the lower surface of the partition 2 9, and the bottom wall of the mounting groove 15 is movably connected to a movable plate 17 through a tension spring 16. The upper surface of the movable plate 17 is in contact with the lower surface of the partition 2 9. A mud discharge hole 18 is also provided on the partition 2 9. A sealing block 19 is fixedly connected to the movable plate 17 and inserted into the mud discharge hole 18. The sealing block 19 is truncated cone-shaped, and its top end is inserted into the mud discharge hole 18 to ensure that when the movable plate 17 is separated from the partition 2 9 by a small distance, the settled sludge between the partitions 1 8 and 2 9 can be discharged through the gap between the sealing block 19 and the mud discharge hole 18.

[0028] When the energy-saving and environmentally friendly water resource utilization device is working, the coarsely filtered sewage is injected into the housing 1 through the water inlet pipe 2, and the sewage enters the filter mechanism 5 through the water inlet 10 and passes through the annular filter screen 54 and then enters the space between the partition 1 8 and the partition 2 9. The sewage water level rises and is filtered through the filter screen 12 and then discharged through the drain pipe 4. The working rhythm of the driving mechanism 6 is preset, and the cylinder 61 drives the motor housing 62 to move downward, so that the insertion rod 72 is inserted into the top ring 51 and the bottom ring 52 through the water inlet 10, and the insertion rod 72 is inserted into the top ring 51 and the bottom ring 52. During the cleaning process, the sealed pressure ring 73 enters the annular groove 55 and is blocked, so that the sewage no longer enters the filter mechanism 5 in the cleaning state. Then, the scraper rubber ring 77 follows the insertion rod 72 to continue to move downward. When entering between the top ring 51 and the bottom ring 52, the scraper rubber ring 77 stretches to open the annular filter screen 54 outward, and the part of the annular filter screen 54 blocked by the elastic rope 53 is embedded in the tooth groove 14. The scraper rubber ring 77 follows the insertion rod 72 to move downward, scrapes the sludge on the annular filter screen 54 and pushes it to the sealing rubber ring 56, and the scraper rubber ring During the downward movement of the mud rubber ring 77, the sealed pressure ring 73 blocks the top ring 51, which causes the sewage in the partition 1 8 and the partition 2 9 to be sucked into the inner side of the annular filter 54 through the annular filter 54, completing a backwashing. The mud scraper rubber ring 77 continues to move downward with the mud to open the sealing rubber ring 56 and press on the movable plate 17 to complete the sludge discharge. The movable plate 17 is pushed downward to form a gap with the partition 2 9, and the sealing block 19 is separated from the mud discharge hole 18. The sludge deposited on the partition 2 9 will also be discharged. Compared with the past The sludge in the filter mechanism 5 and the sludge discharged from the sludge discharge hole 18 bring out more water, which can wash the sludge pushed on the movable plate 17, and the sludge is discharged through the sewage pipe 3. Then the cylinder 61 drives the motor housing 62 to move upward, the plug rod 72 disengages from the filter mechanism 5, the sealing rubber ring 56 is reset, the sealing pressure ring 73 disengages from the annular groove 55, and the sewage enters the cleaned filter mechanism 5. The driving motor 63 drives the rotating shaft 64 to rotate and adjust the position of the cross bar 71, and the above-mentioned cleaning operation is performed on the remaining filter mechanisms 5.
