[0018] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a domestic sewage treatment device with efficient sedimentation function, including a support column 1 installed at the center of the sewage pool, a reduction motor 2 is embedded on the top of the support column 1, a feed hopper 3 is installed on the rotating shaft of the reduction motor 2, tubular screw conveyors 4 are installed on both sides of the feed hopper 3, a plurality of discharge pipes 12 are installed on the bottom surface of the tubular screw conveyor 4, a hose 13 is installed at the lower end of the discharge pipe 12, a storage barrel 5 is installed at the other end of the hose 13, a plurality of discharge holes 6 are provided below the storage barrel 5, and an adjusting mechanism for driving the storage barrel 5 to rotate synchronously is installed on one side of the plurality of discharge barrels.

[0020] In this embodiment, a fixing plate 14 is provided on both sides of the storage barrel 5, one end of the fixing plate 14 is mounted on the tubular screw conveyor 4, and a sealed bearing is embedded in the other end of the fixing plate 14. A shaft is installed at the outer wall surface of the storage barrel 5 facing the inner ring of the sealed bearing, and the other end of the shaft is installed in the inner ring of the sealed bearing. The shafts on one side protrude outward and are installed with gears 9, and the adjustment mechanism is arranged above the plurality of gears 9;

[0021] The material storage barrel can be positioned by the fixing plate, the sealing bearing and the shaft rod, so that the material storage barrel can only rotate around the shaft rod as the center.

[0022] In this embodiment, the adjustment mechanism includes a rack 8, a cylinder 10, a fixed frame 11 and a slider 15. The rack 8 is meshed and connected with multiple gears 9. The piston rod of the cylinder 10 is installed on one end of the rack 8. A fixed frame 11 is installed between the cylinder 10 and the tubular screw conveyor 4. A slide groove is axially provided on the top surface of the rack 8. There are multiple sliders 15, and the sliders 15 are all slidably set in the slide grooves. The upper ends of the sliders 15 are installed with connecting plates 7, and the other ends of the connecting plates 7 are installed on the outer wall surface of the tubular screw conveyor 4.

[0023] In this embodiment, the cross-sections of the slider 15 and the slide groove are both arranged in a "T"-shaped structure, so that the rack can only move back and forth along the slider, thereby ensuring the stability of the rack during movement.

[0024] In this embodiment, one end of the screw conveying rod inside the tubular screw conveyor 4 extends to the inside of the feed hopper 3, so that the tubular screw conveyor can smoothly discharge the sewage treatment agent in the feed hopper to the outside.

[0025] A ladder is set up between the sewage pool and the feed hopper, so that the staff can approach the feed hopper along the ladder and pour the sewage treatment agent (polyaluminium chloride) into the feed hopper. During the process of entering, the tubular screw conveyor is started, and the sewage treatment agent in the feed hopper can be input into the interior of the tubular screw conveyor through the tubular screw conveyor, and enter into different storage barrels along various discharge pipes and hoses;

[0026] After the above is completed, the reduction motor is started to rotate back and forth continuously. The start of the reduction motor drives the feed hopper and the tubular screw conveyor. The rotation of the tubular screw conveyor drives the storage barrel, so that the storage barrel rotates in the sewage pool with the support column as the center, and the sewage treatment agent is quickly dissolved in the sewage through the discharge hole, and the uniformity of distribution is increased by stirring;

[0027] During the stirring process, the cylinder can be started to make the piston rod of the cylinder continuously extend and retract back and forth. The movement of the piston rod pushes the rack, causing the rack to continuously move back and forth along the slider. The movement of the rack can drive the gear to rotate. The rotation of the gear drives the shaft and the storage barrel, so that the storage barrel can be continuously lifted or lowered, and the height of the storage barrel in the sewage can be changed to ensure that the sewage treatment agent is distributed in the sewage at different depths, further increasing the sedimentation effect.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
