[0029] Please refer to Figures 1-3 This embodiment provides a sedimentation separation device for wastewater treatment, including: a support frame 1; a sedimentation mechanism, the sedimentation mechanism including a sludge thickening tank 2, a sedimentation channel 3, a water flow separation component, a guide channel 4, and a collection tank 5. The sludge thickening tank 2 is disposed on the support frame 1, the sedimentation channel 3 is disposed above the sludge thickening tank 2, the sedimentation channel 3 has two sedimentation zones 7, and there is a conveying gap 6 between the two sedimentation zones 7 for conveying the liquid to be settled to the sludge thickening tank 2. The water flow separation component is disposed in the sedimentation channel 3, the guide channel 4 is disposed at the input end of the sedimentation channel 3 and is connected to the conveying gap 6, the collection tank 5 is disposed at the output end of the sedimentation channel 3, the output end of the sedimentation channel 3 is provided with a drain outlet 8 connected to the collection tank 5, the collection tank 5 is provided with a drain pipe, and the guide channel 4 is provided with an inlet pipe 9. The water flow separation component includes several inclined plates 10 arranged parallel to each other in the sedimentation channel 3 and a drive frame for adjusting the angle of the inclined plates 10.

[0030] In this embodiment, the support frame 1 is used to provide stable support to ensure that the equipment will not tilt or collapse due to factors such as gravity or water flow impact during operation.

[0031] In this embodiment, the aforementioned sedimentation mechanism utilizes gravity to gradually settle suspended particles in the wastewater during the sedimentation process, thereby achieving solid-liquid separation. Specifically, the aforementioned sludge thickening tank 2 is used to reduce the water content of the sludge, allowing water to be separated from the sludge through natural sedimentation, thus increasing the sludge concentration. The aforementioned sedimentation channel 3 is used to transport wastewater upwards in a bottom-up manner. Due to the gravity of the particles in the wastewater, water and particles are separated within the sedimentation channel 3.

[0032] In the embodiment, the water flow is evenly distributed by the mutually parallel inclined plates 10 in the water flow separation assembly, avoiding local accumulation or short circuit of water flow in the sedimentation area 7, so as to ensure uniform water flow conditions in the entire sedimentation area 7 and improve the sedimentation effect. During the sedimentation process of the inclined plates 10, the suspended particles gradually deposit on the inclined plates 10 under the action of gravity to form a sludge layer. With the thickening of the sludge layer, part of the sludge will slide along the inclined plates 10 to the bottom of the sedimentation tank, and the clear water will rise through the gaps between the inclined plates 10 to realize solid-liquid separation.

[0033] In the embodiment, the setting of the flow guide groove 4 ensures that the liquid to be settled can uniformly enter the sedimentation flow channel 3, and the water collecting groove 5 is responsible for collecting the settled clear water and discharging it through the drainage pipeline. The water flow path is optimized, avoiding short circuit and dead zone of water flow, and improving the drainage effect.

[0034] It should be noted that the inclined plate 10 is a telescopic structure for adapting to the angle change in a fixed space.

[0035] Please refer to Figures 1-3 In some embodiments of the embodiment, the driving frame includes a support cross bar 11 and an adjusting sliding cylinder 12, the support cross bar 11 is arranged at the top of the sedimentation flow channel 3, the adjusting sliding cylinder 12 is slidingly sleeved on the support cross bar 11, and the inclined plate 10 is hinged to the adjusting sliding cylinder 12.

[0036] In the embodiment, the inclined angle of the inclined plate 10 is adjusted by driving the adjusting sliding cylinder 12 to slide with the support cross bar 11, so as to facilitate the user to adjust the inclined angle of the inclined plate 10 according to the use requirement.

[0037] Please refer to Figures 1-3 In some embodiments of the embodiment, a locking knob 13 is arranged between the support cross bar 11 and the adjusting sliding cylinder 12, the locking knob 13 is threadedly connected with the adjusting sliding cylinder 12, and the locking knob 13 can abut against the support cross bar 11.

[0038] In the embodiment, the locking knob 13 is threadedly connected with the adjusting sliding cylinder 12, and the locking knob 13 is continuously close to or away from the support cross bar 11 by rotating, so as to realize the fixation and sliding of the adjusting sliding cylinder 12.

[0039] Please refer to Figures 1-3 In some embodiments of the embodiment, a sludge concentration tank 2 is arranged at the bottom of the sludge concentration tank 2, and the sludge concentration tank 2 includes an arc-shaped groove 14 and a feeding auger 15, the arc-shaped groove 14 is arranged in the sludge concentration tank 2, and the feeding auger 15 is rotationally arranged in the arc-shaped groove 14.

[0040] In this embodiment, the above-mentioned feeding auger 15 rotates in the arc-shaped groove 14, effectively transporting the sludge settled at the bottom of the sludge thickening tank 2. The sludge can be continuously and stably discharged from the sludge thickening tank 2, avoiding the accumulation and blockage of the sludge. The cooperation of the feeding auger 15 and the arc-shaped groove 14 makes the transportation and settling process of the sludge more efficient. This helps to reduce the time required for sewage treatment and improve the overall treatment efficiency.

[0041] Please refer to Figures 1-3 In some embodiments of this embodiment, the above-mentioned sludge thickening tank 2 is provided with a driving element 16, and the output end of the driving element 16 is connected with the feeding auger 15.

[0042] In this embodiment, the above-mentioned driving element 16 is the basis for the normal operation of the sewage discharge mechanism, which provides stable power to ensure that the feeding auger 15 can continuously and stably rotate in the arc-shaped groove 14, thereby effectively discharging the sludge from the sludge thickening tank 2.

[0043] Please refer to Figures 1-3 In some embodiments of this embodiment, the above-mentioned driving element 16 is a servo motor.

[0044] In this embodiment, the above-mentioned servo motor refers to the engine that controls the operation of mechanical elements in the servo system, which is an auxiliary motor indirect speed change device. The servo motor can control the speed and the position accuracy is very accurate, and can convert the voltage signal into torque and speed to drive the control object. The excellent control accuracy of the servo motor is an ideal material as the driving element 16, but it is not limited to the above-mentioned servo motor material, and other materials with similar performance can also be used.

[0045] Please refer to Figures 1-3 In some embodiments of this embodiment, the above-mentioned sludge thickening tank 2 is of a conical structure.

[0046] In this embodiment, the above-mentioned sludge thickening tank 2 of a conical structure helps the settling and thickening of the sludge. Due to the design of the conical bottom, the sludge will gradually gather to the center during the settling process, thereby improving the settling efficiency and thickening effect of the sludge. The conical structure of the bottom makes it difficult for the sludge to remain. During the settling process, the sludge will gradually slide down the conical wall to the bottom, reducing the adhesion and residue of the sludge on the wall, and helping to keep the sludge thickening tank 2 clean and efficient.

[0047] In use, the liquid to be settled enters the guide groove 4 through the water inlet pipe 9, and enters the sludge thickening tank 2 through the conveying gap 6, and continuously accumulates and settles in the sludge thickening tank 2. With the continuous input of water, the water flows out through the settling flow channel 3. Due to the gravity of the particles in the sewage, the particles continuously accumulate in the sludge thickening tank 2, and the water continuously flows out through the settling flow channel 3, and then is separated by settling in the settling flow channel 3, and then is output to the water collecting tank 5 through the water outlet 8 and conveyed to the next work station.

[0048] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
