[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1 , the utility model provides a technical solution:

[0025] A rotary spray cleaning device for sludge at the bottom of an air flotation machine comprises a fixed bracket 1, a fixed base 4 is installed on the top of the fixed bracket 1;

[0026] A driving device 3 is installed inside the fixed base 4, a connecting rod 5 is installed on the top of the driving device 3, a bearing 6 is sleeved on the top of the connecting rod 5, a bearing gasket 7 is installed on the top of the bearing 6, a rotating fixed base 8 is installed on the top of the bearing gasket 7, a built-in water pipe 13 is interspersed at the center position of the driving device 3, the connecting rod 5, the bearing 6, the bearing gasket 7 and the rotating fixed base 8, a rotating shaft 10 is fixedly connected to the top of the rotating fixed base 8, the rotating shaft 10 is hollow, a branch pipe 9 is fixedly connected to the outer wall of the rotating shaft 10, a main pipe 11 is fixedly connected to the outer wall of the branch pipe 9, a nozzle 12 is fixedly connected to the outer wall of the main pipe 11, a water inlet pipe 2 is fixedly connected to the outer wall of the fixed base 4, the water inlet pipe 2 passes through the fixed base 4 and is connected with the built-in water pipe 13, and the built-in water pipe 13 is rotatably connected to the rotating shaft 10.

[0027] Through the above technical solution, the main structure is made of stainless steel to ensure good durability and stability in underwater environments.

[0028] Before cleaning the bottom of the flotation machine, first make sure that the flotation machine is stopped and the discharge system is closed. At the same time, check the status of the cleaning device and ensure that all nozzles and rotating devices are operating normally.

[0029] Start the driving device 3 of the cleaning device. Once started, the driving device 3 will start to rotate the rotating shaft 10. As the rotating shaft 10 rotates, the nozzle 12 starts to spray high-pressure water. The water flows through the nozzle 12 to form a strong water column and sprays toward the bottom surface. The direction and angle of the water flow can be adjusted according to specific needs to ensure that all areas of the bottom are covered. The high-pressure water flow flushes the sludge and silt at the bottom and completely removes them from the bottom surface. At the same time, the impact force of the water flow can break up the sludge clumps and make them easier to be washed away. During the cleaning process, the sludge and silt at the bottom are driven by the water flow and gathered in the sludge collection tank or the collection port. Then it is discharged into the sludge treatment system through the drain or pipe for further treatment and disposal.

[0030] After the cleaning process is completed, the control system automatically stops the operation of the cleaning device according to the preset time interval or sludge accumulation, saving energy and maintenance costs;

[0031] Embodiment 2:

[0032] See also Figure 1 , and combined with Example 1, it is further obtained that at least four fixed brackets 1 are provided, and the four fixed brackets 1 are distributed in a circular array at the bottom of the fixed base 4, the four fixed brackets 1 are fixedly connected to the fixed base 4, the connecting rod 5, the bearing 6 and the bearing gasket 7 are all built into the interior of the fixed base 4, the connecting rod 5 is connected to the rotating shaft 10 through the bearing 6, the bottom of the rotating fixed base 8 is adapted to the top of the fixed base 4, the rotating fixed base 8 is fixedly connected to the top of the fixed base 4, at least four branch pipes 9 are provided, and the four branch pipes 9 are distributed in a circular array outside the rotating shaft 10, and a plurality of nozzles 12 are provided, and the plurality of nozzles 12 are distributed in a circular array on the outer side wall of the main pipe 11, and the plurality of nozzles 12 are arranged in the same rotation direction.

[0033] Through the above technical solution, a rotary water spraying method is adopted, and the water flow direction is adjusted to different angles through the driving device 3 to achieve all-round water spraying coverage. Multiple water spraying ports can be designed to make the water flow more uniform, thereby improving the coverage area and water spraying efficiency.

[0034] After the cleaning process is completed, the control system automatically stops the operation of the cleaning device according to the preset time interval or sludge accumulation, saving energy and maintenance costs.
