Among them, the two sides of the sewage treatment chamber 1 connected to the sedimentation tank 4 are parallel and not perpendicular to the horizontal plane, so that the sedimentation tank 4 can be rotated to be misaligned with the sewage treatment chamber 1 to discharge the sludge, thereby improving the sewage discharge efficiency of the sewage treatment device.

[0032] Furthermore, if Figure 4 As shown, the curvature of the inner surface of the sedimentation trough 4 is not less than that of the inner surface of the sewage treatment chamber 1, so that the sludge on the inner wall of the sewage treatment chamber 1 can more easily slide into the sedimentation trough 4, and because the curvature of the inner surface of the sedimentation trough 4 is not less than that of the inner surface of the sewage treatment chamber 1, the sedimentation trough 4 can deposit more sludge, making the sewage treatment chamber 1 less likely to be blocked, thereby improving the sewage discharge efficiency of the sewage treatment device.

After the rotating motor 3 is started to reset the sedimentation tank 4, the cleaning nozzle 10 is started to clean the sedimentation tank 4 and the inner wall of the sewage treatment chamber 1, so that the sludge on the inner wall of the sewage treatment chamber 1 falls into the sedimentation tank 4. At the same time, the sludge that has not fallen in the sedimentation tank 4 is also washed away. After the washing is completed, the rotating motor 3 is started to pour the sludge in the sedimentation tank 4 into the sludge treatment chamber 8, thereby achieving the purpose of cleaning the sewage treatment chamber 1 cleanly and efficiently, avoiding the filter screen and the sewage treatment chamber 1 being blocked by sludge, causing obstacles to sewage treatment, and improving the efficiency of sewage treatment.

The water outlet pump is started to discharge the water in the water purification chamber 11 through the water outlet pipe, thereby avoiding manual operation and reducing the workload of the staff.

[0040] In order to facilitate a deeper understanding of the technical concept and advantages of the underground sewage treatment device of the present application, the following Figures 1 to 4 Describe the structural form of the underground sewage treatment device with relatively comprehensive and relatively preferred features of the present application.

[0041] A sewage treatment chamber 1 is arranged in the sewage treatment box, and filters are arranged in sequence inside and at one end of the sewage treatment chamber to treat sewage. A water inlet pipe 2 is arranged at the other end of the sewage treatment chamber 1, and a rotatable sedimentation tank 4 is arranged at the bottom of the sewage treatment chamber 1. A mounting block is arranged at the lower end of the filter, a rotating motor 3 is arranged on one side of the mounting block, and a rotating tank 7 is arranged on the other side of the mounting block, wherein the rotating motor 3 is connected to the sedimentation tank 4, and a rotating shaft 6 is arranged at one end of the sedimentation tank 4 away from the rotating motor 3, and the rotating shaft 6 is installed in the rotating tank 7. A sealing gasket is arranged between the rotating shaft 6 and the rotating tank 7 to prevent sewage from entering between the rotating tank 7 and the rotating shaft 6, to prevent sludge in the sewage from hindering the rotation of the rotating shaft 6, and to protect the connection between the rotating shaft 6 and the rotating tank 7 from being damaged by silt. The service life of the equipment is improved. At the same time, a sludge treatment chamber 8 is arranged at the lower part of the sewage treatment chamber 1. The sludge in the sedimentation tank 4 can be poured into the sludge treatment chamber 8 for treatment by rotating the rotary motor 3. No manual operation is required. A sewage pipe 9 is arranged on one side of the sludge treatment chamber 8. A sewage pump is arranged on the sewage pipe 9. A sewage outlet is arranged at one end of the sewage pipe 9 away from the sludge treatment chamber 1. The sewage outlet is connected to a storage device. The sludge discharged from the sewage pipe is discharged and stored through the storage device to prevent the sludge from harming the environment. The sewage treatment chamber 1 and the sedimentation tank 4 form a cylindrical sewage treatment space. The sludge deposited on the inner wall of the sewage treatment chamber 1 will naturally slide into the sedimentation tank 4 due to the inner wall of the cylinder, so that the sewage treatment chamber 1 is not easy to be blocked, which improves the drainage of the sewage treatment device. The sewage treatment chamber 1 has a sewage treatment efficiency in which the two sides connected to the sedimentation tank 4 are parallel and not perpendicular to the horizontal plane, so that the sedimentation tank 4 can be rotated to be misaligned with the sewage treatment chamber 1 to discharge the sludge. The inner surface curvature of the sedimentation tank 4 is not less than the inner surface curvature of the sewage treatment chamber 1, so that the sludge on the inner wall of the sewage treatment chamber 1 is easier to slide into the sedimentation tank 4, and because the inner surface curvature of the sedimentation tank 4 is not less than the inner surface curvature of the sewage treatment chamber 1, the sedimentation tank 4 can deposit more sludge. A vibrator 5 is arranged on the outer wall of the sewage treatment chamber 1 to facilitate shaking the sludge on the inner wall of the sewage treatment chamber 1 into the sedimentation tank 4. A plurality of cleaning nozzles 10 are arranged on the upper part of the sewage treatment chamber 1, and a water pipe is connected to the plurality of cleaning nozzles 10. After the sewage treatment is completed, the sedimentation tank 4 The sludge in the sedimentation tank 4 is rotated to fall into the sludge treatment chamber 8. After the sedimentation tank 4 is reset by starting the rotating motor 3, the cleaning nozzle 10 is started to clean the sedimentation tank 4 and the inner wall of the sewage treatment chamber 1, so that the sludge on the inner wall of the sewage treatment chamber 1 falls into the sedimentation tank 4. At the same time, the sludge that has not fallen in the sedimentation tank 4 is also washed away. After the flushing is completed, the rotating motor 3 is started to pour the sludge in the sedimentation tank 4 into the sludge treatment chamber 8, so as to achieve the purpose of cleaning the sewage treatment chamber 1 cleanly and efficiently, avoid the filter and the sewage treatment chamber 1 being blocked by sludge, hinder the sewage treatment, and improve the efficiency of sewage treatment. The end of the sewage treatment chamber 1 away from the water inlet pipe 2 is embedded in the water purification chamber 11, and the water purification chamber 1 is provided with a water outlet pipe, and the water outlet pipe is provided with a water outlet pump.Start the water outlet pump to discharge the water in the water purification chamber 11 through the water outlet pipe, avoiding manual operation and reducing the workload of the staff.

[0042] It can be seen from the above description of the present application that a rotatable sedimentation tank 4 is arranged at the bottom of the sewage treatment chamber 1. The sedimentation tank 4 is driven to rotate to discharge the sludge deposited in the sedimentation tank 4 after the sewage is filtered into the sludge treatment chamber 8 below the sewage treatment chamber 1. There is no need to remove the sludge manually, thereby reducing the workload of the staff. At the same time, the present application also improves the structure. The sewage treatment chamber 1 and the sedimentation tank 4 form a cylindrical sewage treatment space, and the curvature of the inner surface of the sedimentation tank 4 is not less than the curvature of the inner surface of the sewage treatment chamber 1, so that the sludge on the inner wall of the sewage treatment chamber 1 can more easily slide into the sedimentation tank 4, thereby improving the sewage discharge efficiency and cleaning effect of the sewage treatment device.

Within the technical concept of the present application, the technical solution of the present application can be subjected to a variety of simple modifications, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present application will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed in the present application, and all belong to the protection scope of the present application.
