Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a device for treating algae in a secondary sedimentation tank. Background Technology

[0002] In wastewater treatment, the sedimentation tank used for wastewater settling after biological treatment is usually called a secondary sedimentation tank or final sedimentation tank. It is an important component of the activated sludge system and is often used for sludge-water separation and sludge thickening. Because the effluent from wastewater treatment plants is eutrophic water containing large amounts of nutrients such as nitrogen and phosphorus, under suitable light and temperature conditions, a large amount of algae will grow on the effluent weir and tank walls of the secondary sedimentation tank. The falling algae can clog the filter membrane of the microfiltration tank, causing the microfiltration tank to overflow and affecting wastewater treatment. Therefore, it is necessary to clean the algae in the secondary sedimentation tank regularly.

[0003] There are currently several ways to clean moss, such as manual scrubbing, installing shade nets, and sun exposure. Manual scrubbing is labor-intensive, inefficient, and requires a lot of investment. While installing shade nets to reduce sunlight has some effect, the overall effect is not obvious. Sun exposure will delay the sewage treatment time, and the moss is prone to recurrence after being exposed to water, resulting in poor moss treatment effect. Utility Model Content

[0021] Please see Figure 1-3This utility model provides a technical solution: a device for treating algae in a secondary sedimentation tank, including a track 1. Several positioning plates 2 are fixed to the side of the track 1 for support and positioning. The track 1 is positioned at the edge of the secondary sedimentation tank by bolts or anchors. The positioning plates 2 increase the contact area between the track 1 and the ground, improving its structural strength and stability during use. A mounting frame 3 is slidably mounted on the track 1, and the mounting frame 3 is equipped with a traveling mechanism that drives it to move on the track 1. A connecting frame 4 is mounted above the mounting frame 3, and a connecting frame 4 is mounted on its side. The positioning frame 7 is equipped with a cleaning component. The cleaning component is used to treat the moss on the walls of the secondary sedimentation tank. During the treatment process, the walking mechanism can be controlled as needed. The walking mechanism drives the mounting frame 3 to move, so that the mounting frame 3 moves the cleaning component on the positioning frame 7 through the connecting frame 4, which facilitates the cleaning of the entire tank wall and ensures the effective treatment of moss on the walls of the secondary sedimentation tank. The height of the positioning frame 7 is in the same plane as the track 1, so that the cleaning component is set in a recessed position. After the track 1 is fixed, the cleaning component is located in the secondary sedimentation tank and is set close to the tank wall.

[0022] The cleaning assembly includes a water spray pipe 71 installed on the lower side of the positioning frame 7. Several high-pressure nozzles 72 connected to the inner cavity of the water spray pipe 71 are installed on the side of the water spray pipe 71, and the high-pressure nozzles 72 are evenly arranged along the length of the water spray pipe 71. A protective frame 75 covers the outside of the water spray pipe 71, and the high-pressure nozzles 72 are located on the open side of the protective frame 75. A water supply assembly connected to the inner cavity of the water spray pipe 71 is provided on the side of the positioning frame 7. High-pressure water is supplied to the water spray pipe 71 through the water supply assembly. The high-pressure water entering the water spray pipe 71 is sprayed out through the high-pressure nozzles 72. The sprayed water acts on the moss and removes it from the pool wall. This treatment device uses high-pressure water to clean moss, which has high cleaning efficiency and cleaning quality, and can be used for cleaning at any time as needed.

[0023] The water supply assembly includes a high-pressure pump set 73 installed on the side of the positioning frame 7. A water inlet pipe 74 is installed at the water pumping end of the high-pressure pump set 73, and the water outlet end of the high-pressure pump set 73 is connected to the inner cavity of the spray pipe 71.
