Large-flux Ultra-fine Grid System with Non-rotating Screen Plates

A grid system, comprising:

• a grid body (1) and supports (2), wherein the grid body (1) comprises a water intake module (100), a filtering module (200), a residue scraping module (300), a residue pressing module (400), and a water discharge module (500);
• the filtering module (200) is disposed at a middle-upper part of the grid body (1), the water intake module (100) and the residue pressing module (400) are coupled at a lower part of the filtering module (200), and the water intake module (100), the residue pressing module (400), the filtering module (200), and the residue scraping module (300) are located on a cylindrical barrel (3) disposed on the grid body (1);
• the water intake module (100) comprises a water inlet (5) and a water distribution area (6);
• the filtering module (200) is configured to be arranged on a slightly curved surface, and comprises a water retaining platform (7), an inflow water guide plate (8), a first aperture screen plate area (9), a second aperture screen plate area (10), and a central water retaining weir (11) located in a center of the filtering module (200), the first aperture screen plate area (9) and the second aperture screen plate area (10) are both inclined downwards in the direction of the central water retaining weir (11), with an angle of 5-10° to the horizontal plane;
• the residue scraping module (300) comprises scrapers (12), a driving motor (15), a support frame (16), a residue inlet (17), and a guide rail (18);
• the residue pressing module (400) comprises a squeezing cylinder (19), a motor (20), and a residue outlet (21);
• the water distribution area (6) is fitted to the lower part of the filtering module (200), a right side of the water distribution area (6) is aligned with a left side of the first aperture screen plate area (9), a left side of the water distribution area (6) is aligned with a right side of the water retaining platform (7), a left side of the water retaining platform (7) is coupled and integrated with the guide rail (18), the second aperture screen plate area (10) is formed between the first aperture screen plate area (9) and the residue inlet (17), and the squeezing cylinder (19) is connected to the residue inlet (17) by ways of grid residue baffles on both sides;
• the support frame (16) is disposed on the supports (2), the driving motor (15) is disposed on the support frame (16), and the scrapers (12) are driven by the driving motor (15) to rotate continuously;
• the residue outlet (21) is reserved at an outlet end of the squeezing cylinder (19), and the motor (20) and the residue outlet (21) are diagonally disposed on both sides of the cylindrical barrel (3);
• and
• the water discharge module (500) is disposed at a lower part of the grid body (1) and located on a conical barrel (4) disposed on the grid body (1), and a water outlet (23) is reserved in a bottom of the conical barrel (4).
