After the initial sealing is completed, the pitch-adjusting rack 1004 is driven to slide longitudinally by rotating the gear 2 504 on both sides, so that the rectangular pressing plate 1006 drives the circular adjusting plate 1101 to slide longitudinally, so that after the initial sealing is completed, the secondary sealing plate 1103 slides downward to achieve the effect of secondary sealing, and the secondary sealing plate 1103 is pressed against the secondary sealing plate 1104. During the downward sliding process of 03, the waste liquid in the upper part of the internal cavity of the sedimentation funnel 6 flows into the top of the secondary sealing plate 1103 through the one-way valve 12, reducing the waste liquid content at the bottom of the cavity of the sedimentation funnel 6, so that when the discharge valve 7 is opened to discharge the wastewater sediment, the discharge content of excess wastewater can be reduced; the combination of the primary seal and the secondary seal ensures the complete sealing of the sedimentation funnel 6 and avoids the leakage of waste liquid. The design of the secondary sealing plate 1103 not only enhances the sealing effect, but also guides the flow of waste liquid through the one-way valve 12, thereby reducing the content of waste liquid at the bottom of the sedimentation funnel 6. When discharging wastewater sediment, the discharge of excess wastewater can be reduced, thereby improving the efficiency and quality of waste liquid treatment.
