detailed description

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

As shown in Figure 1, the domestic sewage purification device includes an outer cylinder pool 1, an inner cylinder pool 2, a grid plate 3, a sewage pipe 4 and a collection box 5, the outer cylinder pool 1 is in the shape of a capsule, and the outer cylinder pool 1 has a cavity, the two sides of the outer cylinder pool 1 are respectively provided with a water inlet 6 and a water outlet 7, and the water inlet 6 and the water outlet 7 are all connected with the cavity, and the position of the water inlet 6 is lower than that of the water outlet 7, and the inner cylinder pool 2 It is a cylindrical shape with both ends penetrating. The inner cylinder pool 2 is rotatably arranged in the outer cylinder pool 1 and its rotation axis coincides with the central axis of the outer cylinder pool 1. There is a circle of inner edges extending from the inner wall of the inner cylinder pool 2. This circle The distance from the inner edge to the side wall on the side where the water inlet 6 of the outer cylinder pool 1 is located corresponds to the length of the inner cylinder pool 2, and the inner edge is fixedly connected to the grid plate 3, and the grid plate 3 is densely provided with A number of through holes 8 for filtering solid impurities, one end surface of the inner cylinder pool 2 is in close contact with the side wall on the side where the water inlet 6 of the outer cylinder pool 1 is located, and the cylinder edge of the other end surface of the inner cylinder pool 2 is in contact with the inner Butted along the rotation, the grille plate 3 is just set at the end face of the inner cylinder pool 2, an inner hole 9 is provided under the inner cylinder pool 2, and an outer hole 10 is provided under the outer cylinder pool 1, and the inner hole 9, The size of the outer hole 10 and the sewage pipe 4 match each other, the sewage pipe 4 passes through the outer hole 10 on the outer cylinder pool 1 and connects with the inner hole 9, and the lower inner wall of the inner cylinder pool 2 has a certain slope and is inclined towards the inner hole 9 direction, a vibrator 11 is provided at the bottom of the inner wall of the outer cylinder pool 1. The vibrator 11 has a vibrating head 12 and the vibrating head 12 can touch the outer wall of the bottom of the inner cylinder pool 2. A drive is also provided in the collection box 5. The cylinder 13 and the sewage pipe 4 are straight pipes. The piston rod driving the cylinder 13 is located in the sewage pipe 4 and can move back and forth in the direction where the center line of the sewage pipe 4 is located. The end of the piston rod is provided with a sealing cap 14. The size of the cap 14 corresponds to the inner hole 9. After the piston rod moves up and down, the sealing cap 14 can block or deviate from the inner hole 9, the outer cylinder pool 1, the inner cylinder pool 2, the grid plate 3, the sewage pipe 4 and the collection box 5 are all detachable connections.

The outer cylinder pool 1 is buried in the ground, and the sewage directly enters the inner cylinder pool 2 through the water inlet 6. At this time, through the function of the grid plate 3, the sewage will flow out from the opening of the grid plate 3, and the large particles of solid impurities It will be intercepted by the grid plate 3 and stay in the inner cylinder pool 2. When the solid impurities in the inner cylinder pool 2 accumulate too much, the drive cylinder 13 will be activated to lift the sealing cap 14 upwards, and then the inner hole 9 and the sewage pipe will be separated. 4 connected, at this time, the solid impurities of large particles in the inner cylinder pool 2 can flow into the collection box 5 from the sewage pipe 4, and because the lower inner wall of the inner cylinder pool 2 has a certain slope towards the direction of the inner hole 9, the large particles All the solid impurities tend to move toward the inner hole 9. Now start the vibrator 11, and the vibrating head 12 will constantly knock on the bottom of the inner cylinder pool 2, so that these solid impurities are more likely to move toward the inner hole 9. It is worth mentioning that the water inlet 6 and the water outlet 7 of the outer cylinder pool 11 are at different heights, and the device can also serve as a lifting well when the sewage flow rate is slow.
