The lower end of the drain pipe 4 penetrates the housing 1 and extends to the inside, and the drain pipe 4 is fixedly connected to the housing 1. The drain pipe 4 The upper end is L-shaped;

The interior of the housing 1 is located below the drainpipe 4 and is provided with a filter screen 7, and the edge position of the lower surface of the filter screen 7 is fixedly connected with evenly distributed first springs 6, and the lower end of the first spring 6 is fixedly connected There is a fixed block 5, one end of the fixed block 5 is fixedly connected with the inner wall of the housing 1, the lower end of the water injection pipe 3 runs through the filter screen 7, and the two are slidably connected.

One end of the paddle 10 is fixedly connected with a second spring 11, and one end of the second spring 11 is fixedly connected with a small steel ball. 12.

Specifically, as shown in FIG. 5 , two sets of U-shaped pipes 13 are fixedly connected to the lower end of the water injection pipe 3 , and the open ends of the U-shaped pipes 13 face upward.

Specifically, as shown in Fig. 6 and Fig. 7, the upper end of the U-shaped tube 13 is provided with a cover plate 14, and a first connecting block 17 is fixedly connected to one side of the outer circular surface of the cover plate 14, and the first The inside of the connecting block 17 is provided with a rotating shaft 18, and the rotating shaft 18 is fixedly connected with the first connecting block 17. The side surfaces of the two ends of the rotating shaft 18 are wound with torsion springs 19, and the two ends of the rotating shaft 18 are fixed to rotate. Two connection blocks 20, one end of the second connection block 20 is fixedly connected to the U-shaped pipe 13, one end of the torsion spring 19 is fixedly connected to the second connection block 20, and the other end of the torsion spring 19 is connected to the first connection block.

Specifically, as shown in FIG. 1 , the lower end side surface of the housing 1 is gradually gathered and has an inclined design, and the lower end edge of the housing 1 is fixedly connected with support legs 2 that are evenly distributed.

By adopting the above technical scheme, in order to quickly extract the suspended solids in the black water, the black water added with flocculant is passed into the water injection pipe 3, and the black water flows into the U-shaped pipe 13 along the water injection pipe 3, and finally flows from the U-shaped pipe 13 The open end of the casing 1 is discharged, and the black water is gradually filled in the housing 1. As the black water gradually rises, it is finally discharged from the drain pipe 4. The drained black water will push the cover plate 14, and the cover plate 14 will turn up and drive the first connection. The block 17 rotates together with the rotating shaft 18, and the torsion spring 19 also twists at the same time, and the black water will be filtered through the filter screen 7 when it rises. Compared with the traditional filter, the filter screen 7 is installed below the opening of the water injection pipe 3. This will easily lead to blockage of the filter screen 7. The utility model utilizes the water pressure rise in the housing 1 to filter the black water through the filter screen 7. The sediment in the black water will drop due to its own gravity and settle to the bottom of the housing 1, thereby The problem of clogging of the filter screen 7 is reduced, and compared with the suspended solids in the naturally deposited black water in the sedimentation tank, the solid-liquid separation can be quickly realized and the production efficiency can be improved. When the filtered black water enters the drain pipe 4, it will push the paddle 10 to rotate. The curved design of the paddle 10 can increase the contact area with the black water, so that the black water can push the paddle 10, and the paddle 10 is rotating. Can drive second spring 11 and small steel ball 12 to rotate when rotating, and small steel ball 12 can knock filter screen 7 when rotating, and filter screen 7 can vibrate up and down after being knocked, the first spring 6 that filter screen 7 bottoms are installed It is convenient for the filter screen 7 to vibrate up and down, and the filter screen 7 can further reduce the sediment in the black water to block the filter screen 7 when it vibrates up and down. The sediment settles to the bottom of the shell 1 with gravity, and the U-shaped pipe 13 is installed with the opening facing upwards to prevent the black water entering the shell 1 from impacting the sediment at the bottom of the shell 1, because the sediment will be suspended in the shell again after being impacted 1, thereby increasing the settling time. By observing the sewage pipe 16, we can know whether there is sediment in the sewage pipe 16. When there is sediment in the sewage pipe 16, it is necessary to open the sewage valve 15 to discharge the sewage, and then close the sewage valve 15 after the sediment is discharged. The lower end of the housing 1 The folded design facilitates the sediment at the bottom of the housing 1 to slide into the sewage pipe 16 along the slope of the bottom of the housing 1, thereby facilitating sewage discharge.

When stop injecting black water in water injection pipe 3, the open end of U-shaped pipe 13 no longer has black water to discharge, and cover plate 14 is no longer subjected to the impact force of black water simultaneously, twisted torsion spring 19 can restore original state simultaneously and can drive The first connecting block 17 rotates and cooperates with the gravity of the cover plate 14. The cover plate 14 will quickly seal the opening of the U-shaped tube 13, which can avoid the problem that the sediment in the housing 1 will flow back into the U-shaped tube 13 when it sinks. .
