Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment sand sedimentation device. Background Technique

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and it is also increasingly entering the daily life of ordinary people;

[0003] Sewage treatment requires the cooperation of multiple steps, including sand sedimentation. After adding drugs to the sewage and mixing, it needs to precipitate for a certain period of time, so that the sediment in the water sinks downward, and the clear water on the upper layer can be pumped out, and then the precipitated sediment can be drained away;

[0004] When discharging the sediment after sand sedimentation, due to the certain adhesiveness of the sediment, it is very easy to adhere to a layer on the inner wall of the sand sedimentation tank. It is difficult to effectively and quickly drain it completely when discharging the sediment. At the same time, due to the large area of the sand sedimentation tank, relying solely on manual cleaning will increase the workload of workers, which is very inconvenient;

[0005] Therefore, this application proposes a sewage treatment sand sedimentation device. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Example, consisting of Figures 1-6Given that, the utility model includes a grit chamber 1. An annular slide rail 2 is installed on the inner side wall of the grit chamber 1. An installation seat is installed on the annular slide rail 2. The installation seat includes a vertical plate 4. One side of the vertical plate 4 is fixedly connected with a sliding sleeve 5. The sliding sleeve 5 is sleeved on the annular slide rail 2. The vertical plate 4 is slidably connected to the inside of the grit chamber 1 through the annular slide rail 2 and the sliding sleeve 5. The other side of the vertical plate 4 is fixedly connected with a horizontal plate 7. A motor 8 is fixedly connected to the top of the horizontal plate 7. The output shaft of the motor 8 is fixedly connected with a friction wheel 9. An opening 6 is formed on one side of the vertical plate 4. The friction wheel 9 penetrates through the opening 6, and the outer end of the friction wheel 9 is in contact with the inner side wall of the annular slide rail 2. An installation plate 11 is installed at the bottom of one side of the vertical plate 4. Two connecting blocks 10 are fixedly connected between the vertical plate 4 and the installation plate 11. A scraping strip 12 is fixedly connected to each side of the installation plate 11.

[0022] A plurality of fixing piles 3 are fixedly connected to the outside of the annular slide rail 2. The plurality of fixing piles 3 are distributed in a circular array around the central axis of the annular slide rail 2. And the annular slide rail 2 is fixedly connected to the inner side wall of the grit chamber 1 through the fixing piles 3. The annular slide rail 2 can be installed inside the grit chamber 1 through the fixing piles 3. The annular slide rail 2 can be stably fixed and installed inside the grit chamber 1 through the fixing piles 3 distributed in a circular array.

[0023] The scraping strip 12 is made of rubber material, and the cross-section of the scraping strip 12 is triangular. The scraping strip 12 is in contact with the inner side wall of the grit chamber 1, and the installation plate 11 does not contact the inner wall of the grit chamber 1. The rubber material scraping strip 12 has a certain elastic deformation ability. The scraping strip 12 contacts the inner wall of the grit chamber 1, so that the scraping strip 12 can always press against the inner wall of the grit chamber 1 to scrape off the attached sediment. The cross-section of the scraping strip 12 is triangular, which can more easily scrape up the sediment attached to the inner wall of the grit chamber 1.

[0024] A control box 13 is fixedly installed on one side of the grit chamber 1. The motor 8 is electrically connected to the control box 13. Electrical devices such as a controller for controlling the motor 8 are built into the control box 13.

[0025] A sand discharge port 14 is formed at the bottom of the grit chamber 1. The sand discharge port 14 can discharge the sediment after sedimentation. The sand discharge port 14 is closed during the sedimentation process and only opens when discharging sand.

[0026] Working principle:

[0027] After the sewage is introduced into the sedimentation tank 1, sedimentation begins. After the sedimentation is completed, the upper clear liquid can be pumped away, while the sediment at the bottom can be discharged through the sand discharge port 14. When discharging the sediment, it is easy for sediment to adhere to the inner side wall of the sedimentation tank 1 and is not easy to discharge. At this time, the motor 8 can be started. The output shaft of the motor 8 drives the friction wheel 9 to rotate, and the friction wheel 9 is attached to the inner side of the annular slide rail 2, so that the mounting bracket can slide along the annular slide rail 2 inside the sedimentation tank 1. When the mounting bracket slides, it will drive the mounting plate 11 to move together. The scraping strip 12 on the side of the mounting plate 11 contacts the inner side wall of the sedimentation tank 1, thereby scraping off the sediment adhering to its inner surface to facilitate discharge.
