[0039] The cleaning part 6 includes a first rotating ring 601, which is rotatably arranged on the left side of the inner cavity of the dehydration chamber, and a first bracket 602 is fixedly arranged on the outer periphery of the first rotating ring 601; a second rotating ring 607 is rotatably arranged on the right side of the inner cavity of the dehydration chamber, and a second bracket 6071 is fixedly arranged on the outer periphery of the second rotating ring 607; a cleaning roller 603 for cleaning the filter assembly 5 is arranged between the first bracket 602 and the second bracket 6071, and bristles are arranged on the cleaning roller 603;

[0040] This device is a screw-type sludge dewatering machine; during operation, the flocculated muddy water in the flocculation box 2 flows into the filter assembly 5 of the dewatering box 3. When the muddy water passes through the filter assembly 5, the sewage will seep out along the gap between the moving ring piece and the static ring piece of the filter assembly 5 and be discharged downward into the base 1 through the drain port 302. The sewage in the base 1 is discharged outward through the drain pipe connected to the outside of the base 1; at the same time, the sludge is gradually extruded and formed in the filter assembly 5, and finally discharged outward through the mud discharge box 4;

[0041] By means of the cleaning roller 603, when the driving assembly 8 drives the cleaning part 6 to rotate, the first rotating ring 601 and the second rotating ring 607 in the cleaning part 6 rotate, thereby driving the cleaning roller 603 to rotate to clean the top of the filter assembly 5;

[0042] Specifically, the driving assembly 8 drives the cleaning roller 603 to reciprocate and periodically move left and right on the upper half of the filter assembly 5 through the first rotating ring 601 and the second rotating ring 607. The bristles on the rotating cleaning roller 603 can clean the upper side of the filter assembly 5 and remove the solid particles remaining on the top of the ring sheet.

[0043] And through the spray rod 7, the spray rod 7 can spray the bottom of the filter assembly 5 to rinse the bottom of the filter assembly 5, so as to prevent solid particles from remaining at the bottom of the ring sheet and reducing the effective gap between the ring sheets, thereby affecting the discharge of the liquid;

[0044] At the same time, using a brush instead of a spray to clean the top of the filter assembly 5 can reduce the amount of clean water that is caused by directly flushing the top of the filter assembly 5 and is affected by its own weight and penetrates into the filter assembly 5 through the gaps between the ring plates, thereby reducing the impact on the dehydration effect of mud and water.

[0045] Preferably, the left end of the cleaning roller 603 is rotatably connected to the first bracket 602, and the right end of the cleaning roller 603 is rotatably connected to the second bracket 6071;

[0047] The half gear ring 606 is a sector-shaped gear ring; when the cleaning roller 603 moves to the front side and the rear side of the filter assembly 5, the first gear 605 moves out from the half gear ring 606;

[0048] In this embodiment, the driving component 8 drives the cleaning roller 603 to reciprocate and periodically move left and right in the upper part of the filter component 5 through the first rotating ring 601 and the second rotating ring 607; during this process, the first gear 605 moves and rotates along the half gear ring 606, thereby driving the cleaning roller 603 to rotate, so that the cleaning roller 603 will continue to rotate while moving on the upper side of the filter component 5, thereby improving the cleaning effect of the bristles on the cleaning roller 603 on the filter component 5.

[0049] Preferably, the driving assembly 8 includes a driving rod 801, one end of which is rotatably connected to the left side of the inner cavity of the dehydration box 3, and the other end is rotatably connected to the right side of the inner cavity of the dehydration box 3 after passing through the support plate 301 in sequence, and the support plate 301 is rotatably connected to the dehydration box 3; a motor 803 for driving the driving rod 801 to rotate is arranged on the left side of the outer wall of the dehydration box 3; a driving gear ring 608 is arranged on the outer periphery of the first rotating ring 601, and a driving gear 802 corresponding to the first rotating ring 601 is sleeved on the driving rod 801, and the driving gear 802 is meshed with the driving gear ring 608;

[0050] In this embodiment, the motor 803 drives the driving rod 801 to rotate reciprocatingly, and the driving rod 801 drives the driving gear ring 608 and then the first rotating ring 601 to rotate reciprocatingly through the driving gear 802, thereby driving the cleaning roller 603 to reciprocate and move left and right periodically in the upper half of the filter component 5 to clean the filter component 5.

[0051] Preferably, there are two groups of spray rods 7, which are symmetrically arranged on both sides of the bottom of the filter assembly 5;

[0052] The left end of the spray rod 7 is rotatably connected to the dehydration box 3 and passes through the dehydration box 3 to communicate with the external water supply device. The other end passes through the support plate 301 in turn and is rotatably connected to the right inner wall of the dehydration box 3; the support plate 301 is rotatably connected to the spray rod 7; the spray rod 7 is provided with spray holes equidistantly on one side close to the center of the first rotating ring 601;

[0053] The spray rod 7 is sleeved with a second gear 701, and the left inner wall of the dehydration box 3 is rotatably provided with two sets of intermediate gear groups 702, which are respectively meshed with the two sets of second gears 701 on the spray rod 7, and the outer wall of the first rotating ring 601 on the far left is symmetrically provided with two sets of annular racks 609, which can mesh with the two sets of intermediate gear groups 702;

[0055] In this embodiment, after the external water supply device pumps high-pressure water into the spray rod 7, it is sprayed to the bottom of the filter assembly 5 through the spray hole on the spray rod 7 to clean the bottom of the filter assembly 5; when the driving assembly 8 drives the cleaning roller 603 to move clockwise from the uppermost side of the filter assembly 5 to the rearmost side, the annular rack 609 on the rear side is in contact and meshed with the intermediate gear 7021 on the rear side and drives the spray rod 7 on the rear side to rotate counterclockwise through the second gear 701, and the spray angle of the spray rod 7 on the rear side is adjusted to increase the spray area of ​​the filter assembly 5, and at this time, the winding spring 7023 is deformed and stores energy; when the cleaning roller 603 moves to the rearmost side of the filter assembly 5, the spray angle of the spray rod 7 on the rear side is obliquely upward to flush the cleaning roller 603, thereby cleaning the bristles on the cleaning roller 603; and at this time, the first gear 605 moves out of the half gear ring 606, and is affected by inertia. The cleaning roller 603 will rotate a certain number of times, so that the bristles on the cleaning roller 603 can be fully cleaned. When the annular rack 609 is disengaged from the intermediate gear 7021, the winding spring 7023 is released to drive the spray rod 7 to rotate and reset; similarly, when the cleaning roller 603 gradually moves to the frontmost side of the filter assembly 5, during this process, the water spraying angle of the front spray rod 7 can also be adjusted by the front annular rack 609. At the same time, when the cleaning roller 603 moves to the frontmost side of the filter assembly 5, the water spraying angle of the front spray rod 7 can also be obliquely upward to flush the cleaning roller 603; the annular rack 609 is set to make the spray rod 7 cooperate with the first rotating ring 601. As the first rotating ring 601 rotates, not only can the spraying area of ​​the spray rod 7 be increased, but the cleaning roller 603 can also be flushed, thereby increasing the service life of the cleaning roller 603 and thereby improving the cleaning effect of the filter assembly 5.
