Description

Technical Field

[0001] The utility model relates to the technical field of tunnel sewage treatment, in particular to a water conservancy tunnel sewage treatment device. Background Art

[0002] With the continuous development of my country's social economy, the scale of water conservancy project construction has expanded significantly. However, the construction of water conservancy projects will have a significant impact on the natural environment. How to properly treat water conservancy project construction wastewater and reduce damage to the environment is a universal engineering practical problem. Therefore, good tunnel construction wastewater treatment methods and processes are becoming more and more important, and are also of great significance to the green construction of water conservancy projects. At present, water conservancy tunnel sewage treatment devices mostly use physical treatment technology, chemical treatment technology and biological treatment technology;

[0003] Among them, physical treatment technologies include sedimentation and filtration, chemical treatment technologies include coagulation and sedimentation and chemical oxidation, and biological treatment technologies include activated sludge and biofilm.

[0004] Existing water conservancy tunnel sewage treatment devices generally use flocculation and sedimentation to treat water conservancy tunnel sewage. Therefore, the sludge settled at the bottom of the treatment tank is often difficult to clean, which is inconvenient.

[0005] Currently, an existing water conservancy tunnel sewage treatment device (e.g., Patent No. CN220951358U) discloses a water conservancy tunnel sewage treatment device comprising: a treatment tank having an arc-shaped bottom inner wall; a water inlet pipe disposed on one side of the treatment tank; a drain pipe disposed on one side of the treatment tank; a lifting mechanism disposed on the treatment tank; a drive mechanism disposed on the top of the treatment tank; and a stirring mechanism disposed on the lifting mechanism for stirring the sewage and moving the sludge. The water conservancy tunnel sewage treatment device provided by this utility model has the advantages of facilitating the cleaning of settled sludge, achieving high treatment efficiency, and being relatively easy to operate.

[0006] However, during the implementation of the above technical solution, at least the following technical problems were found:

[0007] Although the existing device is provided with an auger, the sludge settled in the treatment box is pushed to the sewage trough by the rotation of the auger, and the sludge is discharged through the collection bucket and the sewage pipe, and the auger of the existing device can be raised and lowered, the treatment box used in the device is square as a whole, and the square treatment box has some corners that cannot be affected by the auger. A large amount of sludge will accumulate in these corners that cannot be processed by the auger and will accumulate for a long time, and there is a possibility of clogging the drainage pipe of the device. Therefore, the existing device has the problem of incomplete sludge treatment. Utility Model Content

[0032] The motor 6 is fixedly mounted on the top surface of the base plate 1 , and the output shaft of the motor 6 is fixedly connected to the first sprocket 601 .

[0033] The transmission shaft 801 is rotatably connected to the axis of the sedimentation bin 204. The end of the transmission shaft 801 away from the sludge collection bin 5 is fixedly connected to the second sprocket 8. The section of the transmission shaft 801 located on the inner side of the sedimentation bin 204 is fixedly connected to the auger 802, which contacts the inner wall of the sedimentation bin 204.

[0034] The chain 7 is engaged and clamped between the first sprocket 601 and the second sprocket 8 .

[0035] One side of the processing chamber 2 is fixedly connected to a water inlet 3, and the water inlet 3 is fixedly provided with a first solenoid valve 301.

[0039] In the second step, after the sludge is discharged, the motor 6 is turned off and the second solenoid valve 401 is controlled to be in an open state. The remaining sewage will be discharged from the water outlet 4. At this time, a round of sewage sedimentation and separation treatment is completed.
