[0027] REFERENCE Figures 1-4 A kind of high-density precipitation device of reclaimed water treatment, including sediment tank 1, sewage tank 11 and water collecting tank 7;

[0028] Supporting legs 10 are fixedly welded at the four corners of the bottom of the sediment tank 1, a plurality of groups of installation grooves 2 are arranged on the inner wall of the sediment tank 1, a first inclined plate 3, a second inclined plate 4, a third inclined plate 5 and a fourth inclined plate 6 are respectively inserted and installed in each group of installation grooves 2, and the heights of the inclined plates in each group increase from left to right in sequence;

[0029] Among them, the first inclined plate 3, the second inclined plate 4, the third inclined plate 5 and the fourth inclined plate 6 are all inclinedly installed in the sediment tank 1, and the inclination angles of the inclined plates in each group are all 45°;

[0030] Secondly, a water collecting tank 7 is installed inside the sediment tank 1 and at the rear side of the fourth inclined plate 6;

[0031] In addition, a water inlet 8 is installed on the side wall of the sediment tank 1 and close to the side of the first inclined plate 3, and the water inlet 8 penetrates the inside of the sediment tank 1, a water outlet 9 is arranged at the rear side of the water collecting tank 7 and penetrates the sediment tank 1.

[0032] In this embodiment, the reclaimed water is injected into the sediment tank 1 from the water inlet 8, because the first inclined plate 3, the second inclined plate 4, the third inclined plate 5 and the fourth inclined plate 6 increase in height from left to right in sequence and the inclination angle is 45°, the impurity particles in the water gradually precipitate to the surface of the inclined plate under the action of gravity during the flow of the water between the inclined plates, and slide along the inclined plate to the sewage tank 11 below, the clean water after the precipitation treatment flows into the water collecting tank 7, and finally is discharged from the sediment tank 1 through the water outlet 9.

[0033] Reference Figures 1-4 A sewage tank 11 is arranged at the bottom of the sediment tank 1 and below the inclined plates in each group, a lead screw 14 is rotatably installed inside the sewage tank 11, a scraper 15 is movably installed inside the sewage tank 11, a screw hole 17 is centrally and penetratively arranged in the scraper 15, the lead screw 14 penetrates the screw hole 17, a servo motor 12 is fixedly installed on the front wall of the sewage tank 11, the output shaft of the servo motor 12 is in transmission connection with the lead screw 14, and a sewage outlet 16 is arranged at one side of the bottom of the sewage tank 11;

[0034] Secondly, the outer wall thread of the lead screw 14 and the inner wall thread of the screw hole 17 are in mutual engagement, and the scraper 15 can be driven by the lead screw 14 to slide in the sewage tank 11;

[0035] Secondly, a gate 13 is fixedly installed at one side of the bottom of the sewage outlet 16.

[0036] In this embodiment, when it is necessary to clean the deposits in the sewage tank 11, the servo motor 12 is started, the lead screw 14 is driven by the servo motor 12 to rotate, because the outer wall thread of the lead screw 14 and the inner wall thread of the screw hole 17 of the scraper 15 are in mutual engagement, the scraper 15 will slide in the sewage tank 11 under the drive of the lead screw 14, the deposits in the sewage tank 11 are scraped and gathered at the sewage outlet 16, at this time the gate 13 is opened, and the deposits can be discharged from the sewage tank 11.

[0037] Working principle: the treated water enters the sedimentation tank 1 through the water inlet 8, and first starts the preliminary sedimentation process in the first inclined plate 3 area. Due to the inclination of the inclined plate by 45°, the water flow forms a laminar state between the inclined plates, the flow rate slows down, and the larger particles in the water start to settle on the surface of the inclined plate under the action of gravity. As the water flow continues to flow to the right to the second inclined plate 4, the third inclined plate 5 and the fourth inclined plate 6 area, the sedimentation process continues, and different particle size impurities are gradually separated and deposited on the inclined plate, and slide along the inclined plate to the lower sewage tank 11. In this process, the height of the inclined plate is designed to increase in turn, so that the water flow can be uniformly distributed and maintain a stable flow state between the layers of inclined plates, avoiding short flow or turbulent flow phenomena, further improving the sedimentation efficiency. The clear water after sedimentation by multiple layers of inclined plates will naturally rise and flow into the water collecting tank 7 located at the rear side of the fourth inclined plate 6, and finally be discharged from the sedimentation tank 1 through the water outlet 9, completing the purification process of the water. When a certain amount of sediment accumulates in the sewage tank 11 and needs to be cleaned, the servo motor 12 is started, and the output shaft of the servo motor 12 drives the screw rod 14 to rotate. Due to the close engagement between the threads on the outer wall of the screw rod 14 and the threads in the screw hole 17 in the center of the scraper 15, under the action of the thread transmission principle, the scraper 15 will slide linearly in the sewage tank 11 along the axial direction of the screw rod 14. During the movement of the scraper 15 from one end to the other end of the sewage tank 11, the sediment deposited at the bottom of the sewage tank 11 is gradually scraped and gathered at the sewage outlet 16. At this time, the gate 13 fixedly installed at the bottom of the sewage outlet 16 is opened, and the sediment is discharged from the sewage tank 11 through the sewage outlet 16 under the action of gravity, thereby realizing the automatic cleaning function of the sewage tank 11, ensuring the continuous and stable operation of the sedimentation device. The whole device is compact in structure, stable and efficient in operation, can effectively improve the quality and efficiency of water treatment, and reduce the operation cost and maintenance difficulty.

[0038] It can be understood that the servo motor driving mode in the present application can be driven by an external power line. The servo motor can be programmed and controlled by a master control system, and its control principle can be realized by existing control technology. The type of servo motor is not limited to a single type and can be any suitable type available on the market.
