[0038] First, the device includes a mounting frame (1), with a through connecting shaft (2) in the center of the mounting frame (1).

A connecting cylinder (3) is provided at the lower part of the connecting shaft (2) near the mounting frame (1). The connecting cylinder (3) is hollow. The structure is connected to the connecting shaft (2) via a sealed rotating connection; a spray pipe (11) is provided between the connecting cylinder (3) and the first scraper (12), the spray pipe (11) is used for high-pressure spraying of water flow and softening of sludge residue in the sedimentation tank (9); an L-shaped guide channel (19) is provided inside the first scraper (12), and a plurality of water outlets (20) are provided between one side of the guide channel (19) and the first scraper (12), for guiding water flow to the area to be cleaned through the water outlets (20); a spray head (16) is provided at the bottom of the first scraper (12), the spray head (16) is connected to the spray pipe (11) through the guide channel (19) and is used for direct spraying of water flow. The spray head (16) is equipped with a regulating valve, which is used to control the water flow rate.

[0039] The motor (7) is an adjustable speed variable frequency motor, which is used to adjust its speed according to different cleaning needs.

[0040] according to Figures 1 to 4 As shown, this embodiment provides an effective sludge residue cleaning device for sedimentation tanks. The device features a unique design, employing a combination of a first scraper (12) and a second scraper (13). During the cleaning process, the two scrapers rotate synchronously via a connecting shaft (2). To improve sludge removal efficiency, the spray pipe (11) within the device can flush the bottom of the sedimentation tank (9) with high-pressure water flow, softening the sludge residue.

The spray head (16), controlled by a regulating valve, can flexibly control the water flow rate, enabling targeted cleaning of sludge with different accumulation levels.

[0041] Through the design of this embodiment, the synergistic action of the first and second scrapers enables comprehensive cleaning of the bottom and walls of the sedimentation tank. The high-pressure spray, combined with the scraper movement, effectively softens stubborn sludge in the sedimentation tank, breaking it down into smaller pieces or a flowing state, reducing scraping resistance and improving cleaning efficiency. Furthermore, the coordination of the spray heads and guide channels effectively ensures the uniformity of the water flow, allowing every sludge point to be effectively treated, thereby significantly improving the device's working efficiency.

[0048] The bottom of the suction pipe (202) is provided with a sludge inlet (17). The softened or flowing sludge is discharged through the suction pipe (202) by the sludge pump (8). The sludge pump (8) is used to remove the sludge in a timely manner during the cleaning process.

[0049] In this embodiment, the connecting shaft (2) is equipped with an inlet pipe (201) and a sludge suction pipe (202). A through hole (14) is provided between the bottom of the inlet pipe (201) and the connecting cylinder (3). Clean water enters the connecting shaft (2) through the inlet pipe (201) and then flows into the spray pipe (11) through the through hole (14).

[0050] The greatest advantage of this embodiment lies in its dual-channel structure. The configuration of the water inlet pipe and the sludge suction pipe makes the cleaning process more efficient, while simultaneously achieving the dual functions of clean water spraying and sludge discharge. The water flow provided by the water inlet pipe (201) softens the sludge in the sedimentation tank, which is then cleaned in conjunction with the scraper. At the same time, the sludge suction pipe (202) effectively discharges the cleaned sludge, ensuring that the cleaning of the tank bottom and walls is not affected by sludge re-accumulation. The highly efficient sludge discharge design of the overall system allows the device to significantly shorten the cleaning cycle in practical applications, avoiding the cleaning difficulties caused by sludge accumulation.

[0053] In this embodiment, the first scraper (12) and the second scraper (13) are connected by a support frame (15). The support frame (15) is fixed to the connecting shaft (2) by a rotatable connection, which ensures that the scraper can rotate stably during cleaning and adapt to different working conditions. The support frame (15) enhances the support force of the scraper when cleaning the pool wall and bottom, ensuring that the scraper can maintain sufficient force for effective cleaning. The support frame (15) is also treated with corrosion-resistant materials to ensure that it is not affected by corrosion when in contact with sludge residue for a long time.

[0054] The connection between the support frame (15) and the scraper further improves the stability and durability of the scraper. During the cleaning process, the support provided by the support frame (15) enables the scraper to maintain stable performance even under high-intensity working conditions, ensuring efficient cleaning. In addition, the use of corrosion-resistant materials extends the service life of the equipment, avoids material corrosion problems caused by long-term use, and improves the overall durability and maintenance cycle of the device.

The slide rail (10) can effectively guide the movement of the pulleys (18), making the rotation of the mounting frame (1) more stable and smooth, thereby improving the working efficiency of the entire device.

[0058] This embodiment, by setting up a pulley and slide rail system, makes the device more stable during rotation, reduces motion resistance, and reduces equipment wear. The guiding effect of the slide rail allows the mounting bracket (1) to rotate more smoothly, improving the stability of scraper cleaning. This design improves the operating efficiency of the device, ensures the continuity of the cleaning process, and helps to extend the service life of the equipment.

[0059] Example 6
