Since there is a torsion spring between the uppermost sector-shaped main filter plate 500 and the sliding ring 114, And the torsion spring is in the accumulating state in the initial state, causing the uppermost sector-shaped main filter plate 500 to rotate along the second guide groove 703 of the guide rod 700. Since the second guide groove 703 has different depths and has a starting part and an ending part, When the sector-shaped main filter plate 500 slides on the guide rod 700, the limiting rod 130 keeps the filter unit coaxial with the guide rod 700. When the uppermost sector-shaped main filter plate 500 rotates, the connecting rod 111 drives the driving ring 110 to rotate synchronously. Since the fixed rod 115 does not rotate at this time and only slides up and down along the guide rod 700, the rotating gear 116 provided on the fixed rod 115 Driven by the driving ring 110, the fixed sleeve 113 is rapidly rotated through the rotating gear 116. Since the lower end of the fixed sleeve 113 is fixedly connected with the scraper 112, the end face of the scraper 112 is in close contact with the upper end face of the uppermost sector-shaped main filter plate 500, and has A certain rotational speed difference causes the scraper 112 to clean the solid impurities blocked on the upper end surface of the uppermost fan-shaped main filter plate 500 .

While the uppermost fan-shaped main filter plate 500 rotates along the second guide groove 703 of the guide rod 700, the first sliding rod provided at the lower end of the uppermost fan-shaped main filter plate 500 moves along the first sliding rod at the upper end of the adjacent lower fan-shaped main filter plate 500. The arc-shaped groove rotates, and at the same time, the radial edge of the uppermost fan-shaped main filter plate 500 scrapes the impurities on the upper end surface of the adjacent lower fan-shaped main filter plate 500, and the first sliding rod of the uppermost fan-shaped main filter plate 500 rotates to the corresponding position. When the first arc-shaped groove on the adjacent lower fan-shaped main filter plate 500 reaches the extreme position, the uppermost fan-shaped main filter plate 500 is driven to rotate synchronously with the adjacent lower fan-shaped main filter plate 500, reciprocating in sequence, and the uppermost fan-shaped main filter plate 500 is moved upward. The impurities are gradually removed.

While the uppermost sector-shaped main filter plate 500 rotates, the sector-shaped sub-filter plate 800 connected to the uppermost sector-shaped main filter plate 500 through the connecting plate 119 begins to rotate synchronously with the uppermost sector-shaped main filter plate 500 for blocking the uppermost sector. The gap opened by the main filter plate 500 prevents impurities in the sewage from being discharged from the gap opened by the uppermost fan-shaped main filter plate 500. When the uppermost fan-shaped sub-filter plate 800 rotates, the second slide of the lower end of the uppermost fan-shaped sub-filter plate 800 The rod rotates along the second arc-shaped groove of the adjacent lower sector-shaped sub-filter plate 800, and gradually unfolds the pair of sector-shaped sub-filter plates 800.

As the uppermost sector-shaped main filter plate 500 rotates, the angle of the spoiler 900 connected through the telescopic rod 118 deflects, and drives the hinge rod 117 to slide in the annular guide groove of the guide block 600, and gradually stretches the hinged rod 117. The second spring between the rod 117 and the starting end of the annular guide groove simultaneously blocks the rotation of the fan-shaped main filter plate 500, slows down the rotation speed of the fan-shaped main filter plate 500 and the scraper 112, and improves the cleaning speed of the fan-shaped main filter plate 500. Slow down, while improving the degree of cleaning of the fan-shaped main filter plate 500. As the spoiler plate 900 rotates, the direction of the sewage flow is changed, and the cleaned impurities on the fan-shaped main filter plate 500 are flushed, so that the impurities blocking the fan-shaped main filter plate 500 flow to the sewage outlet along the inclined fan-shaped main filter plate 500 Within 704.

When the uppermost sector-shaped main filter plate 500 slides to the end along the second guide groove 703, the sector-shaped main filter plate 500 has been cleaned. Since the second guide groove 703 and the third guide groove 702 are smoothly connected, at this time, the compressed Under the action of the first spring 120, the sector-shaped main filter plate 500 and the sector-shaped sub-filter plate 800 slide upward along the spiral third guide groove 702. At this time, the uppermost sector-shaped main filter plate 500 rotates in the opposite direction and will be set on the sliding ring 114. The torsion spring between the uppermost sector-shaped main filter plate 500 accumulates force, and at the same time, the second spring provided between the hinge rod 117 and the starting end of the annular guide groove begins to release force, further pulling the uppermost sector-shaped main filter plate 500 back. Rotate in the direction to quickly reset the main sector filter plate 500, reducing impurities falling onto the sub-sector filter plate 800. As the sub-sector filter plate 800 is reset, the multiple sub-sector filter plates 800 clean each other and there are fewer sub-sector filter plates 800. The impurities will accumulate on the lowermost fan-shaped sub-filter plate 800. When the fan-shaped main filter plate 500 is cleaned next time, the sewage water flow will flush the accumulated impurities into the sewage outlet 704. Repeatedly, the efficiency of sewage treatment is improved.
